More Details on Our Top Picks
HOROW HWMT-8733 Small Compact One Piece Toilet with Soft Closing Seat, Dual Flush, 12” Rough-In, White
This compact one-piece toilet stands out primarily for its space-efficient design, making it ideal for apartments or tight bathrooms where every inch counts. Compared to larger models like the American Standard H2Option, it sacrifices some size for a more streamlined footprint, though it may be too small for larger or taller users. Its powerful dual-flush system offers a reliable water-saving feature, and the soft-close seat adds a level of quiet operation that many users will appreciate in shared spaces. However, its limited size can be a drawback for bigger users or those seeking more comfort. Additionally, the small dimensions mean it may not suit everyone’s aesthetic preferences or ergonomic needs.
Pros:- Space-saving compact design suitable for small bathrooms
- Powerful dual-flush system for water efficiency
- Quiet, soft-closing seat reduces noise
Cons:- May be too small for larger or taller users
- Limited color options and aesthetic flexibility
Best for: Buyers with small bathrooms who prioritize space efficiency and quiet operation.
Not ideal for: Larger households or users seeking a more traditional, larger toilet for comfort and capacity.
- Dimensions:25″D x 13.4″W x 28.4″H
- Rough-In:12 inches
- Seat Height:16.5 inches

Our verdict“This model makes the most sense for those needing a compact, efficient toilet in limited spaces.”
American Standard H2Option Dual Flush Elongated Toilet, Chair Height, White
The American Standard H2Option offers a comfortable chair-height elongated bowl, making it a preferred choice for those valuing ergonomics and ease of use. Its dual flush options of 0.92 and 1.28 GPF deliver reliable water savings while maintaining solid performance, especially compared to simpler single-flush models. The inclusion of an EverClean surface simplifies cleaning, which is a significant advantage for busy households. However, some users may find the dual-flush mechanism less intuitive, especially if they prefer one-touch operation. Its high performance certification and dependable push-button make it suitable for families seeking longevity and ease of maintenance.
Pros:- Water-efficient dual flush system saves water
- Comfortable chair-height elongated bowl
- Easy to clean with EverClean surface
- Dependable push-button operation
Cons:- Some users may find the dual flush mechanism less intuitive

St. Tropez Comfort Height One-Piece Elongated Toilet, Vortex Dual-Flush 1.1/1.6 GPF, White
The St. Tropez combines durability with water-saving technology through its dual vortex flush system, which ensures efficient waste removal with less water. Its ceramic body is scratch-resistant, making it a good choice for high-traffic bathrooms. The elongated bowl provides additional comfort and is suitable for most users, especially those who prioritize long-term reliability. Compared with the American Standard H2Option, this model emphasizes durability and efficiency, with a slightly higher flush volume at 1.6 GPF for demanding situations. Its requirement for a standard 12-inch rough-in limits installation flexibility, but it offers a straightforward, reliable performance for everyday use.
Pros:- Water-efficient dual flush system
- Scratch-resistant ceramic for longevity
- Comfortable elongated bowl
Cons:- Requires standard 12-inch rough-in
- Potentially higher cost due to quality materials
Best for: Homeowners needing a durable, water-efficient toilet with a focus on longevity.

Our verdict“Ideal for buyers who want a durable, high-performance toilet with efficient water use and long-term reliability.”
TOTO Aquia IV Two-Piece Elongated Dual Flush Toilet with CEFIONTECT, Cotton White
The TOTO Aquia IV is distinguished by its 360-degree cleaning technology via DYNAMAX TORNADO FLUSH, which surpasses the vortex system of the St. Tropez for more thorough waste removal. Its skirted design and CEFIONTECT glaze greatly reduce waste buildup, making it easier to maintain and cleaner over time. The dual flush options of 0.9 and 1.28 GPF cater to water savings and high efficiency, especially compared to traditional models. However, this model’s price and the need for additional purchase of seat, wax ring, and hardware can add to the overall cost. It’s best suited to those willing to invest in a high-end, easy-to-clean toilet with advanced flushing technology.
Pros:- Dual flush for water conservation
- Effective 360-degree cleaning with DYNAMAX TORNADO FLUSH

- Higher price point due to advanced features
Best for: Homeowners seeking cutting-edge cleaning technology and a sleek, modern aesthetic.
Not ideal for: Budget-conscious buyers or those with non-standard rough-in sizes without the need for adapters.
- Flush Options:0.9 GPF / 1.28 GPF
- Material:Ceramic with CEFIONTECT glaze
- Design:Skirted, elongated bowl
- Flush Technology:DYNAMAX TORNADO FLUSH
- Color:Cotton White
- Height:Universal Height

Gerber Maxwell Select Elongated Two-Piece Dual-Flush Toilet, White
The Gerber Maxwell Select stands out for its split-flush dual system, providing a straightforward approach to water savings without complex mechanisms. Its soft-close elongated seat enhances comfort and reduces noise, making it suitable for family bathrooms. Compared with the more technologically advanced TOTO Aquia IV, this model emphasizes simplicity and reliability, though it might lack some of the advanced cleaning features. Its high-efficiency design aims to prevent clogs with a smooth trapway, but installation might be more challenging for those unfamiliar with plumbing, as it could require professional setup. Overall, this toilet appeals to buyers seeking a dependable, effective dual-flush with a clean design.
Pros:- Efficient dual-flush system saves water
- Soft-close elongated seat reduces noise
- Design complements various bathroom styles
- Virtually clog-free with smooth trapway
Cons:- May require professional installation
- Elongated seat might not fit smaller bathrooms

- Type:Two-piece toilet
- Color:White
- Flush mechanism:Split-flush
- Flush volume:1.28/1.0 gpf
- Seat:Soft-close elongated
Our verdict“This toilet provides a balanced mix of effectiveness and value for buyers seeking dependable performance without high-tech features.”
TOTO Aquia IV WASHLET+ Two-Piece Elongated Dual Flush Toilet with CEFIONTECT, Cotton White
This TOTO model stands out for combining a sleek, skirted design with advanced flushing technology, making it ideal for those who value both aesthetics and performance. Its dual flush options of 1.28 and 0.9 GPF, powered by the DYNAMAX TORNADO FLUSH, deliver thorough cleaning while conserving water, outperforming many traditional models like the Gerber Maxwell Select. The CEFIONTECT glaze ensures fewer stains and easier cleaning, while the SoftClose seat adds comfort and quiet operation. The main tradeoff is the higher price point, which reflects its premium features, and installation may require professional help for a clean, secure fit. Compared to the Eridanus wall-hung, this is more straightforward to install and maintain but lacks the space-saving benefits of wall mounting.
Pros:- Sleek, skirted design for a modern look and easier cleaning
- Effective dual flush system reduces water use
- Includes SoftClose seat for comfort and quiet operation
- CEFIONTECT glaze prevents stains and buildup
Cons:- Higher price can be a barrier for some buyers
- Installation may require professional assistance
Best for: Homeowners seeking a stylish, high-tech toilet that balances water efficiency with comfort
Not ideal for: Budget-conscious buyers who prioritize affordability over advanced features or modern design
- Flush Options:1.28 and 0.9 GPF
- Color:Cotton White
- Material:Ceramic
- Features:CEFIONTECT glaze, skirted design, SoftClose seat
Our verdict“This model suits those who want a high-end, aesthetically pleasing toilet with proven efficiency and comfort features.”
Gerber Maxwell Select Round Two-Piece Dual-Flush Toilet, White
The Gerber Maxwell Select offers a practical dual-flush solution with 1.28 and 1.0 GPF options, making it a strong choice for those seeking reliable water savings without premium bells and whistles. Its canister flush valve and glazed trapway deliver a powerful, clog-resistant flush that rivals the performance of more expensive models like the TOTO Aquia IV. The soft-close round seat enhances user comfort and reduces noise, though the round shape may not suit those looking for a more elongated, modern aesthetic. Compared with the Eridanus wall-hung, it’s easier to install and maintain but lacks the space-saving, wall-mounted design. It strikes a good balance between affordability and functionality, though it might not satisfy those wanting the latest in design innovation.
Pros:- Water-saving dual-flush options
- Soft-close round seat reduces noise
- Strong, clog-resistant flush system
- Simple, straightforward installation
Cons:- Round seat may not appeal to all users
- Lacks the modern, sleek design of skirted or wall-hung options
Best for: Budget-conscious households needing a dependable, easy-to-maintain dual-flush toilet
Not ideal for: Homes with limited space where a compact or wall-mounted model would be preferable
- Type:Two-piece toilet
- Color:White
- Flush options:1.28 and 1.0 GPF
- Seat:Soft-close round seat
- Features:Canister flush valve, glazed trapway
Our verdict“This toilet is well-suited for those seeking straightforward reliability at an affordable price point.”
Eridanus Wall Hung Toilet with 2×4 In Wall Tank Carrier, Dual Flush, White
The Eridanus wall-hung toilet excels in small or contemporary bathrooms where space and cleanliness matter. Its wall-mounted design creates a floating appearance, making the room look larger and easier to clean underneath—an advantage over traditional floor-mounted models like the Gerber Maxwell or TOTO Aquia. Its dual flush system is equally powerful and efficient, with adjustable height for personalized comfort. The concealed tank and rimless bowl contribute to a sleek, minimalist aesthetic, although the installation process is more complex, often requiring professional help. Additionally, since the toilet and tank are shipped separately, planning for different delivery times is necessary. While it demands a higher upfront effort to install, the space-saving benefits and modern look make it ideal for sophisticated, clutter-free bathrooms.
Pros:- Space-saving wall-hung design enhances room size perception
- Easy to clean with rimless, concealed tank and soft-close seat
- Powerful dual-flush system for water efficiency
- Adjustable height for customized comfort
Cons:- Separate shipping of toilet and tank may cause delays

Factors to Consider When Choosing Dual Flush Toilets 4
Choosing the right dual flush toilet involves more than just picking the most popular model. Several factors influence long-term satisfaction, including water efficiency, comfort, and installation complexity. Understanding these elements helps prevent costly mistakes and ensures your bathroom functions smoothly for years to come.Water Efficiency and Flush Performance
Water savings are a primary reason for choosing a dual flush system, but it’s equally important that the flush effectively clears waste. Look for models with cyclone or vortex flushing technology, which tend to prevent clogs and reduce water use without sacrificing performance. Avoid models with weak flushes that require multiple attempts, as they negate the savings and frustrate users.
Size and Space Requirements
Measure your bathroom carefully before selecting a model. Compact or wall-hung options save space but may require professional installation and specific wall support. Comfort height and elongated bowls generally enhance usability, especially for taller users or those with mobility issues, but they occupy more room. Balance your space constraints with user comfort when choosing the right size.
Ease of Installation and Maintenance
Some toilets are designed for DIY installation, featuring straightforward mounting and fewer parts. Others, especially wall-hung models, demand professional setup and maintenance. Consider the availability of replacement parts and the complexity of cleaning the bowl and trapway. A model with smooth surfaces and accessible components simplifies ongoing upkeep.
Build Quality and Durability
High-quality ceramics and sturdy flushing mechanisms extend the lifespan of your toilet. Cheaper models may develop leaks or cracks over time, leading to costly repairs. Look for reputable brands with proven durability, especially if you plan to use the toilet heavily or in a high-traffic bathroom. Remember, investing a little more upfront can pay off in fewer service calls later.
Additional Features and Aesthetic Considerations
Features like soft-close seats, quick-release mechanisms, and cleaning-friendly surfaces enhance convenience. Color matching and sleek designs can also improve bathroom aesthetics. However, prioritize functionality and durability over bells and whistles—extra features often come at a premium and may not be necessary for everyone.
Frequently Asked Questions
Can I replace my existing toilet with a dual flush model myself?
In many cases, replacing an existing toilet with a dual flush model is feasible for someone with basic plumbing skills. It involves removing the old unit, preparing the flange, and installing the new one, ensuring proper sealing and venting. However, compatibility with your current waste line and space constraints can complicate the process. If you’re unsure about plumbing codes or the complexity involved, consulting a professional can prevent potential issues later.
Are dual flush toilets more prone to clogging?
Generally, dual flush toilets are not more prone to clogging than traditional models, especially if they feature modern vortex or cyclone flushing systems. Proper installation and selecting a model with an effective trapway design are key factors. Regular maintenance and avoiding flushing inappropriate materials also help maintain optimal performance and reduce clogging risks.
How much water can I save with a dual flush toilet?
Most dual flush toilets save a significant amount of water by offering a half-flush option for liquid waste and a full flush for solids. Typical savings range from 20% to 60% compared to conventional toilets, depending on usage habits and model efficiency. Over time, these savings can lead to noticeable reductions in water bills and environmental impact.
What should I consider if I have limited bathroom space?
In small bathrooms, space-saving options like compact or wall-hung dual flush toilets are ideal. These models free up floor space and can make your bathroom feel more open. Be aware that wall-hung models require professional installation and sturdy wall support. Carefully measure your space before choosing to ensure compatibility and ease of access.
Is a more expensive dual flush toilet worth the investment?
Higher-priced dual flush toilets often provide better build quality, more reliable flushing systems, and enhanced features like soft-close seats or quicker installation. For high-traffic or long-term use, investing in a premium model can reduce maintenance and repairs. However, for occasional or budget-conscious users, well-chosen mid-range models can deliver satisfactory performance at a lower cost.
