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 KOHLER K-6428-0 Memoirs Stately Comfort Height Toilet is designed for comfort and efficiency, making it a solid choice for those looking for a reliable one-piece toilet. Its compact elongated bowl provides added sitting comfort while maintaining a smaller footprint, which is great for tighter spaces. The comfort height feature elevates the seat to a chair-like height, facilitating easier use for most adults, particularly the elderly or those with mobility issues.

One of the standout features is its AquaPiston flush technology, which allows water to enter the bowl from all sides. This design not only enhances the flushing power but also reduces the chances of clogs, making it effective in terms of performance. The 1.28 gallons per flush (GPF) water consumption meets WaterSense certification, indicating it is water-efficient and can help save on utility bills.

There are a few points to consider. At 114.49 pounds, this toilet is quite heavy, which may complicate installation if you're not experienced. Although it includes a quiet-close seat, it does not come with a supply line, so you may need to purchase one separately, adding to the overall cost. While the left-hand trip lever may suit most users, some may prefer a right-hand option based on their bathroom layout.

The KOHLER K-5172-0 San Souci is a one-piece toilet designed for comfort and efficient performance. It features a compact elongated bowl that offers more seating comfort than a round bowl while occupying similar space, making it a smart choice for bathrooms where space is limited but comfort matters. This model has a Comfort Height of about 28 inches, which is slightly taller than standard toilets, facilitating easier sitting and standing for most adults.

It utilizes KOHLER's Aqua Piston flushing system, a strong gravity-powered flush that cleans the bowl thoroughly with just 1.28 gallons of water per flush. This low water usage contributes to water bill savings and environmental friendliness. The toilet also includes a concealed trapway and Clean Caps, making it easier to clean and providing a sleek appearance without exposed pipes. Made from durable vitreous china ceramic, it has a smooth white finish that resists stains and scratches. The included seat is a high-density polyethylene Quiet-Close type that prevents slamming and remains securely in place. The left-hand trip lever is standard and easy to operate.

Weighing 94 pounds, the toilet is somewhat heavy and may require two people for safe installation. While the flushing system is powerful, some users might prefer dual-flush models for more water-saving flexibility during light use. Additionally, the left-hand lever placement may not suit all bathroom layouts, so verifying compatibility before purchase is recommended. This KOHLER toilet is suitable for those seeking a comfortable, efficient, and easy-to-clean one-piece toilet with a modern design, especially in smaller bathrooms where space-saving is important.
