10 Best TOTO One Piece Toilets 2026 in the United States

The TOTO MS900CUMFG#01 Neorest NX1 Electronic Dual Flush Toilet offers a blend of luxury and functionality. Its elongated bowl shape provides added comfort, while the dual flush system allows for efficient water usage with 1.0 GPF and 0.8 GPF options. The adjustable heated seat and customizable spray settings ensure a personalized and comfortable experience.

Plus, the auto open/close lid and flush functions make it both convenient and hygienic, especially for households that prioritize cleanliness. Additionally, the automatic air purifying system helps to control odors, adding to the bathroom experience. The toilet's height and trapway design are standard, making it accessible and relatively easy to maintain.

However, at 157.5 pounds, this model is quite heavy, which might make installation a bit challenging and could potentially require professional help. The modern design, finished in Cotton White, fits well in contemporary bathroom settings. While its price point and advanced features cater to a more premium market, this product is ideal for those looking for high-end features and willing to invest in a sophisticated toilet system.

The TOTO NEOREST AS Dual Flush Toilet is a high-end option in the one-piece toilet category, offering numerous advanced features. Its bowl shape is designed for optimal cleaning performance, enhanced by the TORNADO FLUSH system, which provides powerful 360° cleaning to reach all parts of the bowl. The dual flush functionality is highly efficient, utilizing either 1.0 or 0.8 GPF, contributing to water conservation.

The integrated bidet seat includes personal cleansing features, such as a warm water spray with oscillating and pulsating options, an instantaneous water heater, and a heated seat with adjustable temperature control. The PREMIST feature mists the bowl before each use to help minimize waste sticking to the surface, and EWATER+ technology keeps the wand and bowl clean after use, promoting hygiene. The universal height and ADA compliance make it accessible for a range of users, while the seamless seat design and automatic air deodorizer enhance comfort and cleanliness.

Installation might be more complex due to the advanced features, and the product's weight of 97 pounds may require additional support during setup. The remote control can be useful but may take time for users to become accustomed to its multifunctional settings. This toilet is well-suited for users looking for a luxurious, high-tech bathroom experience with efficient flush performance and extensive comfort features.

The TOTO WASHLET+ Aquia IV is a one-piece elongated toilet that combines modern design with advanced hygiene features. Its elongated bowl offers more comfort compared to round shapes, making it suitable for everyday use. The dual flush system uses 1.28 and 0.9 gallons per flush, helping save water without compromising cleaning power, though very low-flow users might prefer models with even lower usage. Installation is standard floor-mounted, fitting most bathrooms. A standout feature is the integrated S7 electric bidet seat with adjustable warm water washes for front and rear cleaning, a heated seat, air deodorizer, and warm air dryer, providing a spa-like experience. The tankless water heater ensures warm water is continuous, enhancing comfort. The toilet also has a concealed water supply and cord, giving it a neat appearance. Additionally, EWATER+ technology helps keep the bowl and wand cleaner with minimal chemicals, reducing maintenance effort.

At about 28 inches tall, the toilet is comfortable for most adults, and the trapway design, typical of TOTO’s quality, supports efficient flushing and clog resistance. On the downside, this model is relatively heavy and might require professional installation, especially to connect the electrical components. It also has a higher price point typical for bidet-equipped models, which may not be ideal for budget-conscious buyers. For those seeking a stylish, easy-to-clean toilet with high-end bidet features and efficient flushing, this model represents a strong choice.
