10 Best One Piece Toilets 2026 in the United States

The EPLO Smart Toilet Bidet U8MAX is a one-piece elongated toilet designed for those seeking advanced hygiene and comfort features. Its standout strength is the powerful but quiet flush system with a top-tier 1000 grams MaP score, which efficiently clears waste while using water economically via a dual flush option (1.6 gallons full flush and 1.1 gallons half flush). The elongated bowl shape offers added comfort over round bowls, and its ADA comfort height (about 17.4 inches from floor to seat) makes sitting and standing easier, particularly for seniors or people with mobility issues. Made from durable ceramic with a smooth finish, it includes a polypropylene seat that is heated and features an automatic open-close lid and flush for hands-free convenience, which adds a modern, hygienic touch. The innovative foam shield helps reduce splashback, keeping the bowl cleaner after each use.

This model also functions as a bidet, offering multiple wash modes with adjustable water pressure, temperature, and an upgraded air dryer that speeds up drying and reduces toilet paper use. Additional luxuries like deodorization, nightlight, and temperature sensing enhance the user experience throughout the year. On the downside, it is quite heavy (116 pounds), meaning installation may require assistance, and the advanced features might involve a steeper learning curve for first-time users. Also, it is floor-mounted, so it fits standard bathrooms but may not suit every space or plumbing setup.

This toilet suits anyone wanting a smart, luxurious, and hygienic bathroom upgrade with reliable flushing and comfort, but it might be more than necessary for those seeking a simple, budget-friendly option.

Its elongated oval bowl offers a spacious seat area, while the ADA-compliant comfort chair height of 17.4 inches makes it easier to sit and stand, especially for seniors or those with mobility issues. Made from ceramic with a smooth finish, the toilet is sturdy and easy to clean. The standout flushing system is an in-tank pump design that delivers a powerful flush without relying on water pressure, certified with a strong 1000 gram MaP score to prevent clogs and keep the bowl clean. The dual flush option helps save water by offering 1.6 gallons for a full flush and 1.1 gallons for a half flush, making it environmentally friendly and cost-effective.

The automatic lid opening/closing and unique men's urinal flush add a touch-free convenience promoting hygiene. However, being a high-tech smart toilet, it may require an electrical outlet nearby and could have a steeper learning curve for users unfamiliar with electronic controls. Also, its footprint is slightly larger than some compact toilets, so check your bathroom space.
