You've seen the heated seat, the self-lifting lid and the built-in bidet at a friend's house, and now your own toilet feels like a cold folding chair. The best smart toilet is either a full one-piece unit or a smart seat that goes on the toilet you already own, and the price gap is huge: about versus over ,000. Here are the four best smart toilets and smart seats in 2026, ranked by reviews, with what you'll need to install each one.

What to Look For in a Smart Toilet

Full toilet or smart seat. A one-piece smart toilet replaces everything and costs to ,100 or more. A smart bidet seat swaps onto your current toilet for about to . If your toilet is fine, the seat gets you most of the features.

An outlet nearby. Both types need a grounded GFCI outlet within reach. If there isn't one, you'll need an electrician before anything else.

Toilet shape. Seats are sold as round or elongated, and they won't fit the wrong one. Measure from the bolt holes to the front edge before you order.

Water supply and plumbing. Smart toilets connect to the existing cold-water line. A full toilet also needs the right rough-in distance (check the listing's dimensions against your floor flange).

Features you'll use. Heated seat, warm-water wash, adjustable pressure and a night light get used daily. Deodorizers and warm-air dryers are nice extras.
