10 Best One Piece Toilets 2026 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 American Standard 2034314.020 Champion 4 One-Piece Toilet stands out for its powerful and clog-free flushing system, featuring a large 4-inch flush valve and a fully-glazed 2-3/8-inch trapway, ensuring reliable performance with each flush. This makes it an excellent choice for households that prioritize efficient waste removal. The toilet's one-piece design means fewer seams and crevices, making it easier to clean compared to traditional two-piece models. The EverClean surface further enhances cleanliness by inhibiting the buildup of stains and odors, which is a significant advantage for maintaining hygiene with minimal effort.

The elongated bowl shape and chair-height design add to the comfort, making it user-friendly, especially for individuals who might have difficulty sitting down or standing up from lower seats. The included slow-close seat is a thoughtful touch, preventing the annoyance of slamming lids and adding to the quiet operation of the toilet. Made from durable vitreous china, it promises longevity and a clean, white finish that fits well with most bathroom decors.

However, the toilet is quite heavy at 118 pounds, which could make installation more challenging without professional help. Additionally, its water consumption is 1.6 gallons per flush (gpf), which is higher than some of the more water-efficient models on the market that use 1.28 gpf or less. This could be a consideration for those particularly focused on reducing water usage. In summary, the Champion 4 is a solid choice for those looking for a powerful, easy-to-maintain toilet with added comfort features, although its weight and water usage might be potential drawbacks for some buyers.

The TOTO MS646234CEMFGN#01 is a one-piece toilet featuring a round bowl shape, which is typically more compact and suitable for smaller bathrooms.

Constructed from durable ceramic with a smooth cotton finish, the toilet has a clean look that fits well in most bathroom styles. It stands about 28.63 inches high, which is around standard height, ensuring comfort for most users. The package includes a plastic seat and the toilet uses floor-mounted installation, common for residential use.

Weighing 118 pounds, this is a sturdy unit that might require two people for installation. This model is a reliable, water-efficient option with basic features, especially suited for spaces where a compact design is important. The round bowl may be less roomy, and the plastic seat offers basic comfort and durability.
