10 Best One Piece Toilets 2025 in the United States

The HOROW T0338W Compact One Piece Toilet is a solid choice for anyone looking for a modern, efficient toilet solution. Its one-piece design not only makes it aesthetically pleasing but also simplifies cleaning, as there are fewer crevices for dirt to hide. The elongated bowl shape enhances comfort, especially for adults, while the chair height of 17.3 inches makes it suitable for the elderly and individuals with mobility challenges, aligning with ADA standards.

In terms of performance, the dual flush system with options for 0.8 and 1.28 gallons per flush is a standout feature, promoting significant water savings while still delivering a powerful flush rated at 1000 grams. This means you can flush effectively without using excessive water, making it environmentally friendly. Additionally, the toilet's ceramic material and glazed finish contribute to its durability and easy maintenance.

Installation is designed to be user-friendly with clear instructions and fewer complications, making it manageable for a DIY enthusiast or a quick job for a plumber. The included soft-closing seat enhances user experience by minimizing noise and providing a touch of luxury. However, some potential drawbacks should be noted. Weighing in at 99.2 pounds, the toilet is relatively heavy, which may pose a challenge during installation if you're not prepared. The seat material, while durable, is plastic, which might not feel as premium as other materials such as wood. Despite its relatively lower sales rank, the HOROW T0338W remains an excellent option for those seeking a compact, stylish, and efficient toilet that meets modern needs, particularly for smaller spaces and accessibility requirements.

The Swiss Madison SM-1T254 St. Tropez One Piece Toilet is a solid choice for those seeking a stylish and efficient bathroom fixture. It features an elongated bowl shape, providing extra comfort and luxury. The toilet's dual flush system, offering 0.8/1.28 gallons per flush (GPF), is an excellent balance between water conservation and effective flushing power. This can help in reducing water bills while maintaining good performance.

With a comfort height of 16 inches, it is easier for most adults to use, especially those with mobility issues, making it a practical option for accessibility. The seamless porcelain design and glossy white finish make it easy to clean and maintain, adding to its aesthetic appeal and hygiene standards. The soft closing seat adds a touch of convenience and prevents slamming, which can be a disturbance in quieter homes. Additionally, the quick-release feature aids in hassle-free cleaning and maintenance.

At 26.6 pounds, this toilet is relatively lightweight, which might not appeal to those seeking a heavier, more robust structure. The included components, such as the flush valve and hardware, simplify installation. On the downside, the toilet requires floor mounting, which may not be suitable for all bathroom layouts. Despite these minor setbacks, the Swiss Madison SM-1T254 is an excellent option for those prioritizing design, water efficiency, and ease of use in their bathroom fixtures.

The TOTO WASHLET+ Aquia IV is a one-piece, elongated toilet that combines effective flushing and modern bidet features. It uses TOTO's Tornado Flush system, which swirls water in a circular pattern to clean the bowl thoroughly and reduces the need for frequent scrubbing. The toilet’s CEFIONTECT glaze helps keep the surface smooth and minimizes waste sticking, making cleaning easier. It comes in a clean Cotton White ceramic finish that is durable and stylish. The toilet is floor-mounted and measures about 28.5 inches deep, 15.5 inches wide, and 27 inches tall, which fits well in most bathrooms and provides comfortable height for sitting.

Water efficiency is a highlight here, with dual flush options using 1.28 gallons for solids and 0.9 gallons for liquids, helping to save water without sacrificing flushing power. The toilet seat included is plastic and part of the WASHLET C5 Bidet Seat system, offering advanced bidet functions to improve hygiene and comfort. The elongated bowl shape tends to be more comfortable compared to round bowls, especially for adults. One thing to note is the weight, around 53.5 kg (118 lbs), which means installation might require some effort and professional help.

This toilet is well suited for those seeking a modern, water-efficient, and hygienic one-piece toilet solution that combines traditional flushing with advanced bidet features. Potential buyers should consider the relatively high price point and the requirement for an electrical connection for the bidet seat.
