Many of the customer's questions focus on compatibility. Most toilets are classified as round or elongated. These toilet shapes come in standard sizes, making it easier to find the right bidet seat or bidet attachment.

Typically, standard toilet sizes will meet the following ranges: Toilet Height (measured from floor to top of tank): 29 to 31 inches (73 cm to 79 cm). Toilet width (measured from the widest point when viewed from the front): 14 to 16 inches (35 cm to 40 cm). Height to seat (measured from floor to top of toilet seat): 16 to 17 inches (40 cm to 43 cm). Depth (measured from front of toilet to back of tank): 28 to 32 inches (71 cm to 81 cm)

Extended toilets are larger than round toilets and are considered more comfortable. Elongated toilets are usually easy to spot when viewed from above.To confirm your toilet size, measure the distance from the toilet seat bolt to the front of the toilet. Extended toilets measure 18.5 inches or 470 mm.

The benefit of a round toilet is a slightly smaller footprint, saving valuable space in smaller bathrooms. Round toilets don't look perfect, but they're easy to identify by specific front-to-back measurements. A round toilet measures 16.5 inches or 419 mm, measured from the toilet seat bolt to the front of the toilet.
