10 Best One Piece Toilets 2026 in the United States

The TOTO MS646234CEMFGN#01 is a one-piece toilet featuring a round bowl shape, which is typically more compact and suitable for smaller bathrooms. It incorporates the Aquia IV dual flush system, offering efficient water use with 0.9 gallons for liquid waste and 1.28 gallons for solid waste, helping save water without sacrificing performance.

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.

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.

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.
