10 Best One Piece Toilets 2026 in the United States

The Moen 5-Series White Tankless Bidet One Piece Toilet combines modern bidet features with the convenience of a one-piece design. Its elongated (oblong) bowl shape offers comfort for most users, and the wall-mounted style saves floor space, though it may require professional installation. The tankless system provides instant water heating, delivering continuous warm water for bidet functions such as front and rear cleansing with adjustable pressure and temperature, offering customization and enhanced hygiene. Features like UV sterilization and self-cleaning nozzles reduce maintenance needs.

The seat includes soft-close and heated sensor controls for added comfort, while various flush options, including automatic and remote controls, enhance convenience and cleanliness. The toilet is made from plastic, which may not feel as sturdy or premium as ceramic or porcelain finishes commonly found in other models.

This toilet is ideal for users seeking advanced hygiene features and comfort in a sleek, space-saving design. Potential buyers should consider the installation complexity due to its wall-mounted, tankless design and verify water efficiency if that is a priority.

The HOROW T0338WM is a well-designed one-piece toilet suited for homeowners seeking a modern and comfortable option. Its elongated bowl shape provides a spacious seating area, and the chair-height design (17.3 inches from floor to seat) makes it especially user-friendly for elderly individuals or anyone needing easier sit-to-stand transitions. 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. The fully-glazed 2-inch trapway helps maintain proper flow and reduces clogs. 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 Moen 3-Series ET1300 is a one-piece elongated toilet combined with a tankless bidet, designed to add comfort and hygiene to your bathroom routine. Its oblong (elongated) bowl shape offers more seating space, which many find comfortable. The toilet features a unique tankless flushing system, making it more compact and modern looking. The height is described as comfort height and ADA compliant, making it easier to sit and stand for most users, including those with mobility needs.

A standout aspect is its advanced bidet functionality: it offers front and rear cleansing with multiple spray options, adjustable water pressure and temperature, a heated seat, and a warm air dryer—all controlled via a remote. This model also includes features to maintain hygiene like UV self-cleaning nozzles and a pre-wetting bowl. The plastic material and white finish provide a clean, crisp look, but plastic seats might not feel as premium as other materials. The soft-close lid and seat add to the quiet, smooth experience.

Installation is floor-mounted and comes with necessary components, but being a high-tech bidet-toilet combo, setup may be more complex than a standard toilet. This product is well suited for buyers looking for a modern, comfortable, and hygienic bidet toilet with advanced features, especially valuable for those wanting ADA compliance and remote control convenience. However, if simplicity or water usage transparency is a priority, other traditional models might be more straightforward.
