The Necessity of High Flange Toilets: Addressing Installation Challenges and Functional Requirements
The primary reason individuals require specific toilets for high flanges stems from the architectural realities of plumbing installations. A toilet flange is the crucial connector between the toilet and the drainage system. When the rough-in dimension for the toilet, which is the distance from the finished wall to the center of the drainpipe, is larger than standard, or if the finished floor level is unexpectedly high, a standard flange might sit too low for a proper seal with a regular toilet. This necessitates a toilet designed with an extended outlet to compensate for the elevated flange, ensuring a watertight and secure connection that prevents leaks and sewer gas escape. Without a toilet designed for this specific configuration, installation would be problematic, requiring costly and intrusive modifications to the subfloor or drainage system.
From a practical standpoint, using a toilet designed for a high flange directly addresses the issue of toilet stability and functionality. A standard toilet, when connected to an elevated flange, may not sit flush with the floor. This can lead to a wobbly toilet, which is not only aesthetically unappeasing but also a safety concern. More importantly, an improper seal at the flange can result in water seepage onto the subfloor, leading to potential water damage, mold growth, and structural issues over time. A toilet engineered for high flanges typically features a longer horn or an extended outlet that ensures the wax ring creates a comprehensive seal, maintaining hygiene and preventing sanitary hazards.
Economically, investing in a toilet suitable for a high flange is often more cost-effective than attempting to rectify a low-sitting flange with a standard toilet. The alternative would involve cutting into the subfloor to lower the flange, or building up the floor around the flange to meet a standard toilet. Both of these solutions are labor-intensive, requiring skilled tradespeople, and can incur significant expenses for materials and labor. Purchasing a purpose-built toilet for a high flange represents a direct solution to the installation challenge, minimizing the need for additional, potentially more disruptive, and expensive modifications to the bathroom’s structure.
Furthermore, the availability of specialized toilets for high flanges caters to the DIY homeowner and professional plumbers alike, simplifying the renovation or replacement process. By offering a readily available product that addresses a common plumbing scenario, manufacturers contribute to more efficient and predictable bathroom renovations. This translates into reduced project timelines and a lower overall cost for homeowners undertaking plumbing upgrades or repairs, making it a sound economic decision that prioritizes both immediate functionality and long-term building integrity.
Understanding the Mechanics of High Flange Toilet Installations
A high flange toilet, often necessitated by specific plumbing configurations, presents a unique set of installation considerations. The fundamental difference lies in the height of the flange relative to the finished floor. Typically, standard toilet flanges sit flush or slightly above the finished floor. However, a high flange extends significantly higher, often due to subfloor repairs, a raised bathroom floor, or the need to accommodate a thicker finished flooring material like tile. This elevation impacts the toilet bowl’s ability to create a proper seal with the drain pipe. Understanding this mechanical interplay is crucial. The wax ring, a critical component for sealing the connection between the toilet and the flange, relies on compression to create a watertight and airtight barrier. When the flange is higher than usual, the standard wax ring might not achieve sufficient compression, leading to leaks or, worse, sewer gas escaping into the bathroom. Therefore, the design of the toilet bowl, specifically its outlet and the way it seats over the flange, becomes paramount.
The bowl’s shape and the height of its outlet are directly influenced by the flange height. To compensate for a higher flange, toilets designed for this scenario often feature a taller outlet or a slightly different bowl profile to ensure the wax ring can be adequately compressed. This isn’t about simply raising the toilet; it’s about the toilet’s intrinsic design that allows it to interface correctly with an elevated flange. Without this specialized design, installers might resort to shimming or using multiple wax rings, a practice generally discouraged as it compromises the integrity of the seal and can lead to instability. The goal is to achieve a stable, leak-free connection without resorting to makeshift solutions. The effectiveness of the seal is directly proportional to the consistent and even pressure applied to the wax ring, which in turn depends on the toilet bowl making firm contact with the flange.
Furthermore, the structural integrity of the connection is also a factor. A toilet that is not properly seated due to an incorrectly matched flange height can rock or shift, placing undue stress on the wax seal and the flange itself. Over time, this can lead to cracks in the porcelain, flange damage, or persistent leaks. The weight distribution of the toilet bowl and tank assembly needs to be evenly supported by the floor and securely anchored through the flange. A toilet designed for a high flange often has a wider base or a bowl shape that inherently provides more stability when positioned over an elevated connection point. This stability is not just about preventing wobbling; it’s about ensuring the long-term functionality and safety of the plumbing fixture.
The process of choosing a toilet for a high flange isn’t merely about aesthetic preference; it’s a technical requirement dictated by your existing plumbing. Recognizing the specific height of your flange, whether it’s 1 inch, 2 inches, or even more above the finished floor, is the first diagnostic step. This measurement will guide your selection towards toilets that are explicitly engineered to accommodate these variations. Ignoring this crucial detail can result in a costly installation process with ongoing problems, such as recurring leaks and the need for frequent repairs. Therefore, a thorough understanding of the mechanical implications of a high flange is foundational to a successful and lasting toilet installation.
Key Features to Consider in High Flange Toilets
When selecting a toilet designed for a high flange, several specific features should be prioritized to ensure a proper fit and reliable performance. The most critical aspect is the toilet bowl’s outlet height and its compatibility with the elevated flange. Toilets engineered for this situation often have a bowl outlet that is positioned slightly lower relative to the tank or base of the toilet, or a more forgiving design that allows for the necessary compression of the wax ring even with a significant flange elevation. This ensures that the toilet sits level and creates a robust seal with the drain. Manufacturers often specify the recommended flange height range for their models, making it essential to consult product specifications before purchase.
Beyond the primary fit, the type and quality of the wax ring or seal included (or recommended) are important. While many toilets come with a standard wax ring, some specialized models might include an extra-thick or reinforced wax ring specifically designed to bridge the gap created by a high flange. Alternatively, installers might opt for wax-free seals, which can offer greater flexibility and durability in compensating for minor height discrepancies. The overall stability of the toilet is also a key consideration. A toilet designed for a high flange should provide a secure and level installation, preventing rocking or wobbling that could compromise the seal. This often translates to a well-balanced design with a stable base that distributes weight effectively onto the floor and flange.
The flushing mechanism and water efficiency should not be overlooked, even with the specialized flange requirement. Modern toilets are designed to be water-conscious, and many high-flange compatible models offer excellent performance with lower gallons per flush (GPF). Look for models that meet WaterSense criteria. Dual-flush options can also be a valuable feature, allowing users to choose between a full flush for solid waste and a reduced flush for liquid waste, further conserving water. The overall build quality of the ceramic and the durability of internal components like the flush valve and fill valve are also important for long-term satisfaction and minimal maintenance.
Finally, ease of installation and maintenance is a practical advantage. While a high flange presents a unique challenge, some toilet designs are more user-friendly, with clearer instructions and readily accessible components. Features like a concealed trapway can make cleaning easier, and the availability of replacement parts can ensure the longevity of the fixture. Ultimately, the best toilet for a high flange is one that seamlessly integrates with your plumbing setup, provides a reliable and leak-free seal, operates efficiently, and is built to last, offering a comfortable and hygienic user experience.
Installation Best Practices for High Flange Toilets
Installing a toilet on a high flange requires meticulous attention to detail to ensure a secure and leak-free seal. The initial step is accurately measuring the flange height. This involves measuring from the finished floor to the top surface of the flange. This measurement is critical for selecting the correct wax ring or sealing solution. Standard wax rings are typically designed for flanges that are flush with or slightly above the finished floor. For higher flanges, you will likely need an extended wax ring or a wax ring with a built-in horn, which can provide a thicker seal. Alternatively, some plumbers opt for wax-free seals, which are often made of rubber or foam and can accommodate greater variations in flange height, offering a more forgiving installation.
Before setting the toilet, inspect the flange itself for any damage, such as cracks or warping. A damaged flange can compromise the seal and lead to leaks, regardless of the toilet or wax ring used. If the flange is damaged, it must be repaired or replaced before proceeding. The closet bolts, which secure the toilet to the flange, should also be in good condition and extend sufficiently to accommodate the thickness of the toilet base and flange. Ensure the bolts are parallel and spaced correctly to align with the toilet’s bolt holes. Once the flange is sound and the bolts are in place, the wax ring is carefully positioned onto the flange, ensuring it sits evenly and without any distortions.
When lowering the toilet onto the flange and bolts, it’s crucial to do so in a single, decisive motion. Avoid rocking or twisting the toilet bowl, as this can break the seal of the wax ring. Once the toilet is in place, apply firm and even pressure to seat it properly. A slight rocking motion may be necessary to distribute the weight evenly and compress the wax ring, but excessive movement should be avoided. The toilet should sit level and stable on the floor. If there’s any wobbling, shims can be used beneath the base to stabilize it, but this should not be relied upon to compensate for a poor wax ring seal.
After the toilet is seated, the nuts on the closet bolts are tightened gradually and evenly. Tighten them alternately, a little at a time, to ensure the toilet remains stable and doesn’t crack. The goal is to snug the toilet down, creating a secure connection without overtightening, which can damage the porcelain or the flange. Once secured, a final check for levelness and stability should be performed. It’s also advisable to fill the tank and flush the toilet a few times, then check for any signs of leaks around the base. A proper installation on a high flange should result in a stable, flush toilet with no visible leaks or water seepage.
Troubleshooting Common Issues with High Flange Toilet Installations
Despite careful selection and installation, issues can arise when fitting a toilet to a high flange. The most common problem is a leaking seal at the base of the toilet. This often occurs when the wax ring is not adequately compressed due to the flange being too high for a standard seal. In such cases, the first troubleshooting step is to disassemble the toilet and re-examine the wax ring. You may need to use an extra-thick wax ring or a wax ring with a taller horn to ensure sufficient compression. Alternatively, a wax-free seal designed for higher flanges could be a more effective solution, providing a more consistent and adaptable seal.
Another prevalent issue is the toilet not sitting level or appearing unstable. This can be a direct consequence of the elevated flange preventing the toilet from resting flush on the floor, even with a proper seal. If the toilet rocks, it indicates an uneven seating, which can compromise the wax ring over time and potentially lead to the toilet cracking. While shims can be used to level the toilet, it’s essential that the primary seal is robust. If significant shimming is required, it may suggest a more fundamental mismatch between the toilet design and the flange height, necessitating a review of the toilet model or the installation method.
A secondary, though less common, problem can be related to the toilet’s trapway height and its interaction with the drainpipe. While most toilets designed for high flanges address the wax ring compression, an unusually tall flange could, in extreme cases, affect the gravitational flow of waste if the toilet’s internal trapway is not sufficiently low relative to the flange. This is less about leaks and more about potential flushing efficiency or clogs. However, this is rarely an issue with toilets specifically marketed for high flange compatibility.
Finally, if you notice sewer gas odors emanating from around the base of the toilet, it is a definitive sign of an incomplete seal. This requires immediate attention, as it indicates a breach in the barrier between the drainpipe and the bathroom air. The troubleshooting process would involve emptying the tank and bowl, removing the toilet, inspecting the wax ring and flange, and re-installing with a correctly sized seal. It’s crucial to approach these troubleshooting steps methodically, addressing each potential cause to ensure a long-lasting and problem-free installation.
The Ultimate Buying Guide: Navigating the Best Toilets For High Flange
The selection of a toilet is a fundamental aspect of bathroom functionality and aesthetics, often taken for granted until a specific installation requirement arises. For homeowners and plumbers alike, encountering a high toilet flange presents a unique challenge that necessitates a tailored approach to toilet selection. A high flange, typically extending more than an inch above the finished floor, can complicate standard toilet installations, leading to potential issues with wax ring compression, stability, and overall sealing. Consequently, identifying the best toilets for high flange installations becomes crucial for ensuring a leak-free, secure, and aesthetically pleasing outcome. This guide offers a comprehensive analysis of the key factors to consider when purchasing a toilet designed to accommodate or effectively mitigate the challenges posed by a high flange, empowering consumers to make informed decisions that prioritize both form and function.
1. Bowl Height and Overall Toilet Profile
When addressing a high flange, the overall height and profile of the toilet itself become paramount considerations. Toilets with standard or “convenient” height bowls, often referred to as “comfort height” or “Right Height” toilets, are generally designed with a bowl height of 17 to 19 inches from the floor to the top of the seat. This slightly elevated bowl height is advantageous because it inherently raises the toilet’s base off the floor. This increased vertical clearance can often compensate for a flange that sits higher than the typical 1/4 inch above the finished floor. For instance, a toilet with a 17-inch bowl height will naturally position its exit point for the waste pipe (the bottom of the bowl’s trapway) higher than a standard 15-inch toilet. This can reduce the dependency on the wax ring’s thickness to bridge the gap and create a secure seal, minimizing the risk of improper compression and subsequent leaks.
Furthermore, the overall base design and skirted profiles of modern toilets can also play a role. Toilets with a more substantial, solid base often provide a more stable foundation, which can be beneficial when dealing with potential unevenness created by a high flange. Skirted toilets, which conceal the trapway, can sometimes offer a slightly more forgiving fit around the base of the toilet, helping to mask any minor discrepancies in fit caused by the flange height. While not a direct solution, the visual integration and perceived stability of a well-designed base can contribute to the overall success of the installation in the context of a high flange.
2. Flange Compatibility and Wax Ring Alternatives
The inherent design of a toilet’s connection to the waste pipe is a critical determinant of its suitability for high flange installations. Standard toilets rely on a wax ring that is compressed between the toilet’s flange and the toilet’s horn (the outlet at the bottom of the bowl). When a flange is significantly high, the standard wax ring may not compress adequately, leading to an incomplete seal and potential leaks. Therefore, toilets designed with specific flange compatibility features or those that readily accept alternative sealing mechanisms are highly desirable. Some manufacturers offer toilets specifically engineered to accommodate varying flange heights, perhaps with a slightly deeper or differently shaped horn.
Beyond the toilet’s design, the availability and efficacy of alternative sealing methods are crucial. While standard wax rings are the norm, specialized wax rings with extended height or reinforced collars are available. Additionally, wax-free seals, often made from rubber or foam, can provide a more consistent and forgiving seal, especially when dealing with less-than-perfect flange alignment or height variations. When considering the best toilets for high flange, it’s essential to investigate whether the toilet manufacturer recommends or offers these alternative sealing solutions, or if they are universally compatible. A toilet that can effectively integrate with a thicker wax ring or a wax-free alternative will offer a more robust and long-lasting solution for a high flange installation.
3. Toilet Trapway Design and Water Seal Depth
The internal trapway of a toilet, responsible for creating the water seal that prevents sewer gases from entering the bathroom, also influences its performance with a high flange. The depth of the water seal, typically measured from the bottom of the trapway outlet to the surface of the water in the bowl, is crucial for both hygiene and odor prevention. A toilet with a deeper trapway and a more substantial water seal can provide a greater margin of error when the flange height is elevated. This is because a deeper trapway means the toilet’s horn sits further down within the overall structure, potentially minimizing the impact of the flange’s upward extension on the crucial seal integrity.
Furthermore, the internal shape and smoothness of the trapway can impact flushing performance. While not directly related to the flange height, a well-designed trapway contributes to efficient waste removal, which is always a desirable characteristic in any toilet. When researching the best toilets for high flange, paying attention to specifications that detail the trapway diameter and the manufacturer’s claims about flushing power can be beneficial. A toilet that offers robust flushing capabilities alongside a design that can effectively accommodate a higher flange will provide a superior overall user experience.
4. Base Stability and Mounting System
The stability of the toilet’s base and the robustness of its mounting system are critical factors, particularly when dealing with the added complication of a high flange. A toilet that is not securely anchored to the floor can wobble, leading to stress on the wax ring seal and potential leaks over time. For high flange installations, where the gap between the toilet base and the flange may be larger, a toilet with a wider and more substantial base offers increased surface area for contact with the floor, promoting greater stability. This wider base provides a more solid foundation, reducing the likelihood of movement.
The quality and design of the mounting bolts and hardware are also essential. Standard toilet mounting kits typically include bolts that pass through the base of the toilet and anchor into the flange or subfloor. When a flange is high, the bolts might not engage as deeply or securely within the flange itself. Therefore, toilets that come with longer, more robust mounting bolts, or those that utilize a secure clamping system for the base, can significantly enhance the stability of the installation. Investing in a toilet with a well-engineered mounting system will provide peace of mind and contribute to the longevity of the seal.
5. Rough-In Measurement and Toilet Shape
While not exclusively tied to flange height, the standard rough-in measurement of a toilet and its overall shape can indirectly influence the ease of installation with a high flange. The rough-in measurement refers to the distance from the finished wall to the center of the flange, typically 12 inches. Most toilets are designed with this standard in mind. However, the shape of the toilet’s base and its proximity to the wall can sometimes become a factor. A toilet with a more rounded or compact base may offer more flexibility in positioning and accommodating slight misalignments that can arise with a high flange.
Conversely, toilets with very angular or closely skirted bases might present challenges if the flange is not perfectly centered or if there are minor obstructions around the flange. When seeking the best toilets for high flange, it’s advisable to consider toilets that offer a slightly more forgiving footprint around the base. Reviewing the toilet’s dimensions and comparing them to the available space around the flange can help avoid installation headaches. While the primary focus remains on the flange-to-bowl connection, a toilet’s overall physical dimensions can contribute to a smoother and more successful installation process.
6. Water Efficiency and Flushing Technology
While the primary concern with a high flange is achieving a proper seal, it’s also prudent to consider the overall performance and efficiency of the toilet. Modern toilets incorporate various flushing technologies designed to optimize water usage and waste removal. Technologies such as dual-flush systems, which offer both a low-volume flush for liquid waste and a full flush for solid waste, can significantly reduce water consumption without compromising performance. Similarly, advancements in flush valve design and trapway engineering can lead to more powerful and efficient waste removal, even in challenging installation scenarios.
When selecting the best toilets for high flange, homeowners should not overlook the benefits of water-efficient models. While the focus is on the installation mechanics, a toilet that also conserves water and performs reliably in terms of flushing is a more sustainable and cost-effective choice in the long run. Manufacturers are increasingly designing toilets that balance effective flushing with reduced water usage, and these innovations can be particularly valuable when compensating for installation complexities. A well-chosen toilet will not only solve the high flange issue but also contribute positively to the bathroom’s overall functionality and environmental impact.
Frequently Asked Questions
What is a “high flange” in the context of toilets, and why is it important for toilet installation?
A “high flange,” also known as an extended flange or raised flange, refers to a toilet flange that is positioned higher than the standard finished floor level. Typically, a toilet flange should be flush with or slightly above the finished floor for a proper seal. A high flange occurs when the flange is installed significantly above the finished floor, often due to thicker subflooring, tile, or a raised bathroom floor. This height difference can create an unlevel surface for the toilet to sit on, potentially leading to leaks at the wax ring seal or instability of the toilet itself.
The importance of addressing a high flange lies in ensuring a secure and leak-free connection between the toilet and the drainpipe. A standard wax ring, designed for a flush or slightly raised flange, will not create an adequate seal if placed on a significantly higher flange. This can result in sewage gases escaping into the bathroom and, more critically, leaks of wastewater onto the subfloor, which can lead to rot, mold, and structural damage. Therefore, selecting a toilet or using appropriate installation accessories is crucial to compensate for this height disparity.
What are the primary challenges when installing a toilet on a high flange?
The primary challenge when installing a toilet on a high flange is achieving a proper and reliable seal between the toilet base and the drainpipe. A standard wax ring, which relies on compression to create a watertight seal, may not compress sufficiently or evenly when the flange is significantly higher than the toilet’s outlet. This can lead to an incomplete seal, allowing water and waste to leak out at the base of the toilet, potentially causing damage to the subfloor and surrounding areas.
Another significant challenge is ensuring the stability of the toilet. A high flange can create an uneven surface for the toilet to rest on, causing the bowl to rock or tilt. This instability can put undue stress on the porcelain and the floor bolts, increasing the risk of cracking the toilet or loosening the seal over time. The aesthetic appearance can also be compromised, with the toilet appearing uneven or not properly seated on the floor.
Are there specific types of toilets better suited for installation on a high flange?
While most standard two-piece and one-piece toilets can be adapted for a high flange, some designs offer inherent advantages or require fewer modifications. Toilets with a more substantial and rigid base, often found in heavier gravity-flush models, can provide better stability even with a slightly uneven flange surface. Similarly, toilets with a well-designed, thick wax ring or those that come with alternative sealing methods (like rubber gaskets) might offer a more forgiving installation.
However, the key to success with a high flange is not solely dependent on the toilet type but on the installation method. The most effective solutions involve using appropriate flange extenders or taller wax rings specifically designed to bridge the height gap. These accessories, when used correctly, can compensate for the flange elevation, allowing a wide range of toilet models to be installed securely and without leaks, regardless of their specific design.
What are the recommended solutions or accessories for installing a toilet on a high flange?
The most widely recommended and effective solutions for installing a toilet on a high flange involve using specialized accessories designed to bridge the height difference. The primary solution is a flange extender or toilet flange spacer. These are typically made of durable plastic or rubber and are designed to fit over the existing flange, effectively raising its surface to meet the toilet base. They often come in various heights or are stackable to accommodate different flange elevations.
Another crucial accessory is a tall wax ring or extra-thick wax ring. These wax rings are formulated to provide a reliable seal even with a greater compression range, compensating for the extra height of the flange. Some modern toilets may also utilize a rubber gasket seal instead of a wax ring, which can sometimes offer a more consistent and adjustable seal for uneven surfaces. It is crucial to measure the height difference between the flange and the finished floor accurately to select the appropriate extender and wax ring for a secure and leak-free installation.
How do flange extenders or spacers work to solve the high flange issue?
Flange extenders, also known as toilet flange spacers or raised flange kits, work by creating a new, elevated mounting surface that sits directly on top of the existing, high toilet flange. These devices are typically constructed from durable materials like heavy-duty plastic or reinforced rubber and are designed to fit snugly over the interior or exterior of the original flange. Their primary function is to effectively “raise” the plane where the toilet wax ring will sit, bringing it closer to the level of the finished floor.
By providing this new, higher seating surface, flange extenders ensure that the toilet bowl’s outlet can properly align with the drainpipe. This allows for the necessary compression of the wax ring (or the proper seating of a rubber gasket) to create a watertight and gas-tight seal. Without an extender, the gap created by the high flange would prevent the wax ring from sealing effectively, leading to leaks and potential unsanitary conditions. The extender essentially compensates for the vertical displacement of the original flange.
What are the pros and cons of using a tall wax ring versus a standard wax ring for a high flange?
Using a tall wax ring for a high flange offers the primary advantage of potentially requiring fewer installation steps and accessories. If the height difference is moderate, a tall wax ring, which is thicker and designed to compress more, can create a sufficient seal without the need for a flange extender. This can simplify the installation process and may be a more cost-effective solution in certain situations.
However, the main con of relying solely on a tall wax ring is its limited effectiveness with significant flange height discrepancies. If the flange is too high, even a tall wax ring may not compress adequately or evenly to form a reliable seal. This can still lead to leaks and instability, potentially requiring the installation of a flange extender anyway. Furthermore, over-compressing a wax ring, even a tall one, can sometimes compromise its integrity and lead to premature failure. Therefore, while a tall wax ring can be a good option for moderate height differences, it’s not a universal solution for all high flange scenarios.
What are the signs that my toilet flange might be too high and requiring specific attention?
Several signs indicate that your toilet flange might be too high and necessitate specific installation considerations. The most common and immediate sign is difficulty in getting the toilet to sit flush and stable on the floor. If you notice the toilet rocking or wobbling after installation, even when the floor bolts are tightened, it’s a strong indicator of an uneven mounting surface, often caused by a high flange.
Another critical indicator is water leaks around the base of the toilet. If you see water seeping out from beneath the toilet, especially after flushing, it suggests that the wax ring is not creating a proper seal with the flange. This can be due to the gap created by a high flange preventing adequate compression. Additionally, the presence of foul odors emanating from the base of the toilet can signify a faulty seal, allowing sewer gases to escape. If you observe any of these issues, it’s advisable to investigate the height of your toilet flange and employ appropriate solutions like flange extenders or tall wax rings.
Final Verdict
Selecting the ideal toilet for a high flange presents unique installation challenges that necessitate careful consideration of specific design features. Our analysis has highlighted that toilets with a longer flush valve and an adjustable flange adapter are paramount. Furthermore, the tank-to-bowl seal and the overall stability of the unit are critical, as these components must compensate for the increased vertical displacement. Understanding the nuances of flange height and toilet bowl projection is essential to avoid common installation pitfalls and ensure a secure, leak-free fit.
In conclusion, the best toilets for high flange installations are those that offer both structural integrity and design adaptability. The optimal choices are characterized by their robust construction, ensuring long-term durability, and their compatibility with various flange configurations through features like extended wax rings or specialized flange connectors. Prioritizing toilets that explicitly state compatibility or offer adjustable mounting solutions will significantly streamline the installation process and prevent potential plumbing issues down the line, ultimately leading to a satisfactory and reliable bathroom fixture.
