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 TOTO WASHLET+ Nexus One-Piece Toilet is an elongated-shaped toilet, which many find more comfortable compared to round bowl designs. The integrated WASHLET+ bidet seat offers a variety of luxurious features including warm water washing, an auto open/close lid, a heated seat, and a warm air dryer. These features can greatly enhance the user experience with customizable settings for temperature and pressure.

Furthermore, the EWATER+ system mists the wand and toilet bowl, helping to keep the unit clean without harsh chemicals. The toilet uses a 1.28 gallons per flush (GPF) system, making it water-efficient and eco-friendly. At 27 inches in height, it is a comfortable height for most users, and its sleek design hides water supply and power cords for a cleaner look.

The toilet and bidet are made from a combination of ceramic and plastic materials, finished in a cotton white color, which can easily fit into most bathroom decors. One potential downside is its relatively high weight at 116 pounds, which might make installation more challenging. Additionally, the bidet seat is made of plastic, which may not feel as premium as other materials. The contemporary design and array of features make it a great choice for those looking to upgrade their bathroom experience with advanced convenience and cleanliness features.

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.
