Dural Durabase XPS 48 in. x 4.5 in. x 3 in. Waterproof Shower Curb Underlayment

The Durabase XPS shower curb is a tile-able XPS foam curb that is coated on all 4 sides with a waterproof proprietary blend of synthetic polymer mortar and an alkali resistant fiber mesh. This gives it a highly rigid structure and exceptional bonding strength. At only 3 inches the curb is aesthetically pleasing and also allows ease and safety upon entry into the shower. The Durabase XPS shower curb can be easily cut down or extended by using a second curb for a custom shower entry.
