About Compact-Elongated (17.5") Toilets toilets

A compact-elongated bowl measures 17.5 inches from the bolt holes to the front of the bowl — halfway between a round-front (16.5") and a full elongated (18.5"). It's the design choice for bathrooms that need elongated comfort but have only round-front floor space. Increasingly the new-construction default for apartments, condos, and tight remodel layouts.

Standard US bowl shapes:

Round-front: 16.5" deep. Comfortable for quick use but cramped for longer sittings. Common in powder rooms.
Compact-elongated: 17.5" deep. Comfort comparable to elongated; floor footprint comparable to round.
