Do Curbless Showers Leak?

Quick answer

Only if they're poorly designed or installed. With a correctly sloped pan, proper waterproofing, the right drain and good splash control, a curbless shower stays as dry as a traditional one.

What is a curbless shower?

A curbless shower (also called zero-threshold or barrier-free) has no raised lip or step. The bathroom floor flows straight into the shower, which makes it easier to use with a walker or wheelchair, or for anyone who wants a safer, open space.

Common causes of leaks and how to avoid them

Cause	How to avoid it
Incorrect slope	Slope the floor toward the drain, about 1/4" per foot
Not enough waterproofing	Use a waterproof membrane beneath tile. Prefabricated showers don't need additional waterproofing.
Poor drainage	Avoid undersized or misaligned drains, which can overflow
No splash control	Add glass panels or a weighted shower curtain to an open shower
