10 Best One Piece Toilets 2025 in the United States

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 HOROW T0338WM is a well-designed one-piece toilet suited for homeowners seeking a modern and comfortable option.

The matte white ceramic finish offers a sleek, contemporary look that fits well in most bathrooms.

This model features a dual flush system with 0.8 and 1.28 gallons per flush options, balancing powerful flushing—evidenced by a strong 1000-gram Max Performance score—with water savings that can reduce consumption compared to older toilets.

Installation is simplified thanks to large mounting holes and clear video instructions, making it manageable with a plumber’s help. The included high-quality, soft-closing seat with stainless steel hinges adds durability and reduces noise.

The toilet weighs around 99 pounds, which may make handling during installation somewhat challenging. Additionally, its 12-inch rough-in size is standard but should be verified against your bathroom’s plumbing to ensure compatibility. This toilet represents a strong option for those prioritizing comfort, water efficiency, and a clean modern look, especially appropriate for accessible bathroom setups.

The Kohler Leap One-Piece Elongated Smart Toilet is a modern and well-equipped choice for those looking for a comfortable and hygienic bathroom fixture.

The fully skirted trapway simplifies cleaning by hiding the pipes and reducing places where dirt can accumulate, while the quiet-close seat prevents loud slamming.

Motion-activated lid opening and closing add a touch of smart technology, enhancing the hands-free experience.

The toilet’s material is high-quality plastic with a sleek white finish that fits well in contemporary bathrooms.
