A bidet toilet seat swaps onto your existing bowl and adds a water wash to the seat. Some models are electric, with warm water and a remote, while others use plain water pressure and need no outlet at all.

The six seats below cover both kinds, all for elongated toilets. Sizes, controls and warranty terms come from each product’s listing page. We have not used these seats ourselves, and the features described are the makers’ own claims.
