Quick Answer

The best bidet for a round toilet is the TOTO Washlet C2 — TOTO makes a dedicated round-bowl version that fits flush without any overhang or awkward gaps.

Round toilets are shorter from front to back (under 16.5 inches from mounting bolts to bowl tip). Many bidet seats are designed for elongated bowls and will stick out past the front of a round toilet. The picks below are either made specifically for round bowls or are universal-fit models confirmed to work well on round toilets.

What You Should Know

To check if you have a round toilet, measure from the center of the mounting bolt holes (where the seat attaches) to the very front tip of the bowl. Round toilets measure about 16.5 inches. Elongated toilets measure about 18.5 inches. If you're between those numbers, go with the round-bowl bidet since a slightly smaller seat looks better than an oversized one hanging off the front. Some brands sell the same model in both round and elongated versions, so double-check you're ordering the right one.

Frequently Asked Questions

How do I know if my toilet is round or elongated?

Measure from the center of the mounting bolt holes to the front tip of the bowl. Round toilets are about 16.5 inches, elongated are about 18.5 inches. You can also eyeball it: round bowls look circular, elongated bowls look more oval-shaped.

Will an elongated bidet seat work on a round toilet?

Technically it will mount, but the seat will overhang the front of the bowl by about 2 inches. This looks bad and can be uncomfortable. Always buy the version designed for your toilet shape. Most brands sell separate round and elongated versions.

Are there fewer bidet options for round toilets?

There are fewer options than for elongated toilets, but all the major brands offer round-bowl versions of their popular models. TOTO, Alpha, Bio Bidet, and Brondell all have round-compatible seats. Non-electric attachments are typically universal and fit both shapes.
