This toilet is an excellent choice for those who value water savings without compromising comfort, featuring dual flush options that are slightly higher in GPF than the One Piece Elongated. Its sleek, seamless one-piece design simplifies cleaning, much like the HOROW T0338W, but with the added benefit of a higher ADA seat at 17.3 inches, ideal for users with mobility needs. The dual flush system conserves water, though it might come at a higher purchase price, especially if the buyer doesn’t need the water efficiency features. Its water certification (WaterSense, DOE) and high MaP score make it suitable for eco-conscious households. However, it requires a standard 12-inch rough-in, limiting flexibility for some remodels. Overall, this model balances efficiency, ease of maintenance, and user comfort.

The ADA height of 17.2 inches makes it accessible, and the included full installation kit simplifies setup. While it prioritizes performance over advanced features, its lack of electric parts means fewer things to break down. Compared with dual-flush models, it offers a straightforward 1.0 GPF, which can conserve water if used correctly.

This model makes sense for bathrooms where space is at a premium, thanks to its compact design while still offering ADA height, similar to the One Piece Elongated. Its dual flush system is at the lower end of GPF, making it highly efficient, though it might not provide the same water-saving flexibility as higher GPF options. The fully skirted, stain-resistant ceramic surface ensures easy cleaning and a sleek look, but the compact dimensions could be a drawback if existing plumbing doesn’t align. The soft-close seat adds comfort and quiet operation, but professional installation might be needed to ensure perfect fit and function. Overall, it’s a practical choice for those wanting a space-saving, water-efficient toilet with ADA height comfort.

Its dual-flush system balances water efficiency with performance, comparable to the Elongated options but in a more compact, round form that fits tighter spaces. The soft-close, quick-release seat enhances user experience, while the stain-resistant glaze simplifies maintenance. Compared to the more elongated models like the One Piece Elongated with Comfort Chair Seat, this one offers a slightly lower seat height but excels in versatility for different bathroom configurations.

Unlike the TOTO Drake, which emphasizes powerful flushing and modern features, the HOROW T0338W prioritizes accessibility and ease of installation in tight quarters.

Factors to Consider When Choosing High Efficiency Toilets
Choosing the right high efficiency toilet involves more than just water savings. It’s essential to consider how well it flushes, its size and height, and the overall ease of installation and maintenance. Understanding these factors helps avoid common pitfalls like underpowered flushing or uncomfortable heights, which can lead to frustration or additional costs down the line. Here are key considerations to keep in mind:Flushing Technology and Water Use
Look for toilets with dual flush systems that allow you to select between a low-volume flush for liquids and a higher-volume flush for solids. The goal is to maximize water savings without sacrificing cleaning power. Toilets rated at 1.28 GPF or less are considered highly efficient, but some models with even lower rates may struggle with clogging if not properly designed. Consider models with pressure-assisted or tornado flush systems for more reliable performance, especially if you have older plumbing or high usage needs.
Comfort and Height
Height matters more than many realize. ADA-compliant models with elongated bowls typically offer better comfort, especially for taller users or those with mobility challenges. However, taller toilets may require more space and could be incompatible with certain bathroom layouts. Compact designs can save space but often sacrifice some comfort. Decide based on your household’s needs and available space, keeping in mind that comfort can influence long-term satisfaction and usability.
Installation and Maintenance
Ease of installation can significantly affect your overall costs and effort. Look for models with straightforward mounting and compatible rough-in sizes, usually 12 inches. Maintenance considerations include access to parts, ease of cleaning, and durability of seals and seats. Skirted models can simplify cleaning but might make repairs more challenging. Prioritize brands with readily available replacement parts and clear installation instructions to reduce future hassles.
Design and Aesthetics
Modern toilets come in various styles, from sleek one-piece designs to more traditional two-piece models. Skirted models tend to look cleaner and are easier to clean, but they often come at a premium. Consider the overall bathroom decor and your preference for visual style and ease of cleaning when making your choice. Remember that a well-designed toilet can enhance your bathroom’s look while providing practical benefits.
Price and Value
High efficiency toilets span a range of prices, from budget-friendly to premium models with advanced features. While investing more can mean better performance, durability, and comfort, it’s important to evaluate whether those features align with your needs. Cheaper models might lack some comfort features or have less reliable flushing, so weigh upfront costs against potential long-term savings and satisfaction. Prioritize models that offer the best balance of efficiency, performance, and durability for your budget.
Frequently Asked Questions
Will a high efficiency toilet clog more often?
Not necessarily. Many high efficiency toilets with advanced flushing technologies like tornado or pressure-assisted systems are designed to handle waste effectively, even at lower water volumes. However, some lower-quality models may struggle with clogging if they lack sufficient flushing power or if the plumbing is not compatible. Choosing a reputable brand and model with positive reviews for performance can help minimize clogging issues and ensure long-term reliability.
Are high efficiency toilets suitable for large families?
Yes, but with some considerations. For households with high usage, look for models with reliable flushing systems and durable construction to handle frequent use. Dual flush options can be especially beneficial, allowing each user to choose a lower water volume for liquid waste and a higher one for solids, maximizing savings. Additionally, models with larger bowls or comfort-height designs can improve user experience for everyone in the household.
How difficult is it to install a high efficiency toilet myself?
Installation difficulty varies depending on your plumbing experience and the specific toilet model. Many high efficiency toilets are designed for straightforward installation with standard rough-in sizes and include detailed instructions. Basic plumbing skills and the right tools are usually sufficient for a DIYer, but if your bathroom setup is unusual or you’re unsure, hiring a professional can ensure a proper fit and avoid leaks or other issues.
Do high efficiency toilets require special cleaning or maintenance?
Most high efficiency toilets are quite similar to traditional models in terms of maintenance. Regular cleaning with non-abrasive cleaners and inspecting seals and seats for wear can extend their lifespan. Some models with skirted designs might be easier to clean because of fewer crevices, but repair access could be more complicated. Always follow manufacturer recommendations for maintenance to keep your toilet functioning optimally over time.
Is a higher-priced high efficiency toilet worth the investment?
Higher-priced models often feature advanced flushing systems, better materials, and enhanced comfort, which can justify the initial investment if you value durability and performance. They tend to last longer and may require fewer repairs, offering savings over the long run. However, if your needs are basic and budget is a concern, a mid-range or budget model can still provide significant water savings without the premium price tag. Consider your usage habits and long-term goals when making your decision.
Conclusion
For general households seeking a reliable, water-saving toilet, the TOTO Drake stands out as the best overall choice, combining performance with durability. Budget-conscious buyers should consider the HOROW T0338W for its affordability and solid efficiency. Those with limited space or aesthetic concerns might prefer the DeerValley Skirted Toilet for its sleek design and ease of cleaning. If you want the latest in technology and comfort, investing in a premium model like the TOTO Neorest could pay off. Match your choice to your specific needs, budget, and bathroom setup for the best results.
