HOROW T0338W One Piece Toilet with ADA Chair Height 17.3″ Dual Flush

Its 17.3-inch seat height makes it easier for seniors or those with mobility challenges to sit and rise comfortably, a notable advantage over the standard 17-inch models like the DeerValley Compact.

The DeerValley Compact One Piece Toilet is designed for small bathrooms where space is at a premium. Its skirted bowl and compact dimensions—just over 24 inches long—make it easier to fit into tight spaces compared to bulkier models like the Gerber Maxwell. The dual flush system offers water savings of up to 16,500 gallons per year, appealing to eco-conscious buyers, but its smaller size may limit compatibility in larger or more heavily trafficked bathrooms. The quiet soft-close seat and easy-to-clean skirted design enhance convenience, though professional installation could be necessary due to plumbing specifics.

- Water-efficient dual flush reduces water use

The dual-flush system—using 1 GPF/1.28 GPF—delivers water savings while maintaining a powerful flush. Heavier ceramic construction means it is durable but may be more challenging to handle during installation, making it better suited for professional setup.

The Gerber Maxwell offers a practical balance of water efficiency and affordability, making it an attractive choice for secondary bathrooms or budget-conscious buyers. Its dual-flush mechanism—using 1.28/1.0 GPF—delivers water savings comparable to more expensive models, and the elongated seat provides added comfort over round options. While it may lack the sleekness or advanced features of the premium DeerValley models, it still features a reliable, clog-resistant glazed trapway and soft-close seat to minimize noise and maintenance.

St. Tropez Comfort Height One-Piece Elongated Toilet, Vortex Dual-Flush 1.1/1.6 GPF, White
The St. Tropez Comfort Height stands out for its combination of comfort, water efficiency, and sleek one-piece construction. Its dual vortex flush system ensures reliable waste removal while conserving water—comparable to the gerber Maxwell’s dual-flush but with the added benefit of a higher seat height that minimizes strain. The elongated bowl offers extra comfort, making it a strong choice for users prioritizing ease of use. However, being a one-piece model, it typically commands a higher price and requires a standard 12-inch rough-in, which might limit installation flexibility. Its durable ceramic surface resists scratches, promising longevity. The absence of features like a soft-close seat could be a drawback for those seeking quieter operation. Compared to the DeerValley models, this toilet offers a more refined look but at a potentially higher cost.

- Elongated bowl enhances user comfort during prolonged use
- Durable, scratch-resistant ceramic surface ensures longevity
Cons:- Requires a standard 12-inch rough-in, limiting installation options
- Lacks features like a soft-close seat, which could increase noise and wear
Best for: Homeowners seeking a comfortable, water-saving toilet with a seamless look and reliable performance.
Not ideal for: Budget-conscious buyers or those with non-standard rough-ins, as the one-piece design and higher price may be prohibitive.
- Flush System:Dual Vortex
- Water Efficiency:1.1/1.6 GPF
- Rough-In:12 inches

Factors to Consider When Choosing Dual Flush Toilets For Water Efficiency And Comfort
When choosing a dual flush toilet for water efficiency and comfort, it’s important to consider several factors that influence both performance and usability. Understanding these key points can help you avoid common pitfalls and select a model that truly meets your needs, whether for a small guest bathroom or a high-traffic family space.Flush Performance and Water Savings
Look for models with proven dual flush mechanisms that deliver reliable performance across both water-saving and full flush modes. Some toilets may save water but struggle with clearing waste, leading to frequent clogs or the need for multiple flushes. Prioritize models with a good balance of low GPF (gallons per flush) ratings and strong flushing power, which often comes from better bowl design or larger trapways. Keep in mind that ultra-efficient models may require more maintenance or have a slightly higher initial cost, but can significantly cut water bills over time.
Comfort and Accessibility
Consider the height and shape of the toilet bowl. ADA-compliant or comfort-height models make sitting down and standing up easier for taller individuals or those with mobility challenges. Elongated bowls tend to be more comfortable than round ones, especially for adults. Soft-close seats enhance comfort by preventing slamming and reducing noise, which is worth investing in if bathroom serenity matters. Remember that taller or larger users may prefer models with increased bowl height for a more natural sitting posture.
Size and Space Requirements
Measure your bathroom space carefully, especially if you’re choosing a compact or skirted model. Compact toilets save space but may compromise on flushing performance or comfort. Conversely, larger, one-piece designs often add to the overall footprint but can be easier to clean and maintain. Skirted designs offer a sleek look and easier cleaning but sometimes come with higher installation complexity. Balancing size with your bathroom layout will help avoid future frustrations or the need for costly renovations.
Build Quality and Maintenance
Durability matters, especially for toilets in high-traffic areas. Look for high-quality ceramic or porcelain with a smooth glaze that resists staining and simplifies cleaning. One-piece toilets tend to have fewer crevices where dirt and mold can accumulate, making maintenance easier. Check the flushing mechanism—pressure-assisted or siphonic systems can differ in noise levels and reliability. Consider the availability of replacement parts and ease of repair, which can extend the lifespan of your investment.
Additional Features and Price
Features like soft-close seats, quick-release lids, and dual-flush buttons can enhance usability and comfort. Some models include water-saving features like larger trapways or specialized bowl shapes that improve flushing efficiency. While premium models offer these extras along with refined design and higher water savings, budget options can still perform well on core features. Be aware that added features often increase the initial cost but may provide long-term convenience and savings in water bills and maintenance.
Frequently Asked Questions
How do I choose between a one-piece and a two-piece dual flush toilet?
One-piece toilets combine the tank and bowl into a single unit, offering a sleeker look and easier cleaning, which is ideal for modern bathrooms. They tend to be more durable but can be heavier and more expensive to install or replace. Two-piece models separate the tank and bowl, making them easier and cheaper to repair or replace individually. Your choice depends on your budget, maintenance preferences, and aesthetic priorities; both can provide reliable water efficiency and comfort when selected carefully.
Is a higher toilet seat height better for water efficiency?
Not necessarily. Higher, comfort-height toilets are generally more comfortable for most users and can be easier to sit down and stand up from, especially for taller individuals or those with mobility issues. However, water efficiency depends more on the flush mechanism and bowl design rather than height alone. Some ADA-compliant models are taller and also designed to optimize water use, making them a good choice for comfort and efficiency simultaneously.
Can I retrofit my existing toilet with dual flush features?
Retrofitting is possible with dual flush conversion kits, but compatibility and performance can vary. These kits typically replace the existing flush valve and handle, allowing you to switch to a dual flush system without replacing the entire toilet. However, for optimal water efficiency and reliability, installing a dedicated dual flush toilet designed for that purpose often yields better results. Be sure to check compatibility with your current plumbing before proceeding with retrofitting.
How much water can I expect to save with a dual flush toilet?
Dual flush toilets can reduce water use significantly, typically using about 1.1 to 1.6 gallons per flush compared to older models that use 3.5 to 7 gallons. This means potential savings of over 50% on water bills in households with frequent use. The exact savings depend on your current toilet’s efficiency and your usage habits, but upgrading to an efficient dual flush model can make a noticeable difference over time.
Are dual flush toilets suitable for high-traffic households?
Yes, but choosing the right model is key. In high-traffic homes, durability and reliable flushing are essential to prevent clogs and frequent repairs. Look for models with proven flushing power, sturdy build quality, and easy-to-clean surfaces. While some water-efficient models may be slightly less powerful, many are designed specifically for high use, combining water savings with strong performance to withstand daily demand without issues.
Conclusion
For households prioritizing overall reliability and water savings, the Toilet One-Piece Water Efficient Dual Top Flush makes an excellent choice. Those seeking the best value can consider the DeerValley Compact One Piece for space-saving design without sacrificing performance. Buyers who want a premium experience might opt for models with extra features like soft-close seats or ADA compliance, such as the HOROW T0338W. Beginners or those on a budget will find the simpler, more affordable models still provide solid water efficiency and comfort, provided they match their bathroom size and user needs. With these options, you can select a dual flush toilet that meets your water-saving goals while maintaining comfort for everyday use.
