10 Best Dual Flush Toilets 2025 in the United States

The Kohler K-5401-PA-0 Veil Comfort Height Skirted One-Piece Elongated Dual-Flush Intelligent toilet offers a mix of advanced features and modern design. It stands out with its dual-flush technology, allowing users to choose between a full or partial flush, which can be cost-effective and environmentally friendly. The elongated bowl shape and chair-height seating provide comfort, while the tankless design and integrated personal cleansing system give it a sleek, minimalist look.

The toilet also boasts a variety of high-tech features, such as a motion-activated lid, LED lighting, a heated seat with adjustable temperature, and a touch-screen LCD remote control for ease of use. Additionally, the self-cleaning function with UV light and electrolyzed water maintains hygiene, and the emergency flush function ensures usability during power outages. Installation is relatively straightforward with standard rough-in requirements and included accessories.

However, some potential drawbacks include its high price point and the reliance on electricity for many of its features, which may be a concern during power outages despite the emergency flush capability. Additionally, its complex features might require a learning curve for some users. This toilet is best suited for those looking for a high-end, technologically advanced toilet with a focus on comfort and modern aesthetics.

The TOTO WASHLET+ Aquia IV is a one-piece, elongated dual-flush toilet designed for floor mounting, making it a good fit for modern bathrooms. It uses 1.28 gallons per flush for solids and 0.9 gallons for liquids, which helps save water compared to traditional toilets. The elongated bowl shape generally offers more comfort. Made from ceramic with a cotton white finish, it’s easy to clean and fits most bathroom styles. The toilet includes a concealed water supply and power cord for the advanced S7 electric bidet seat, which adds features like warm front and rear washing with adjustable water temperature and pressure, a heated seat, automatic deodorizer, and warm air dryer.

The instantaneous water heating ensures you won’t run out of warm water during use. One potential challenge is its weight at nearly 109 pounds, which might make installation a bit more difficult for some. This model is ideal for those looking to combine water-saving dual-flush technology with the luxury and hygiene of a high-end electronic bidet seat in one integrated unit.

The WOODBRIDGE B0931S is a high-tech dual-flush toilet that blends advanced convenience with efficient performance. Its dual flush system uses 1.6 gallons for a full flush and 1.1 gallons for a half flush, helping conserve water without sacrificing cleaning power—this is supported by its excellent 1000-gram MAP flush score, indicating strong flush efficiency. The toilet’s chair-height design (around 17 inches from floor to bowl) is great for people who need extra comfort getting up and down, meeting ADA standards. Made from durable porcelain with a floor-mounted installation, it fits typical bathroom setups.

What sets this model apart are its smart features: the lid opens and closes automatically with motion or a foot sensor, promoting hands-free hygiene. Voice control allows easy operation without bending or touching controls. The bidet functions offer front and rear washes with adjustable pressure and filtered water, plus a movement drying feature that helps reduce toilet paper use, making it eco-friendly. The integrated foam shield helps keep the bowl cleaner by preventing splashes and odors.

On the downside, the toilet is relatively heavy (112 pounds) and larger than some traditional models, which could demand more careful installation. Also, while it includes a cleaning foam dispenser and extra foam is available, this adds an extra maintenance step not found in simpler toilets. The plastic seat may feel less premium compared to other materials. This toilet is ideal for users wanting a sophisticated, hygienic bathroom upgrade that emphasizes comfort, water efficiency, and smart automation. It’s well suited for those who appreciate the convenience of voice and motion controls combined with strong flushing performance. However, if you prefer a simpler, lighter toilet or have a tight installation space, this might be more than you need.
