About TrueDEK Linear Bases

TrueDEK Linear shower bases feature a fully integrated drain gulley molded directly into a structural, pre-pitched base. The drain gulley offers three drain connector locations to ease installation — choose the drain location that’s best for your job site, or choose to install multiple drains to handle high volume water flow.

As a structural shower foundation, a TrueDEK Linear base may be installed directly on joists to make a curbless shower that’s flush with the rest of the bathroom floor.

Precisely pre-sloped, each base ensures swift and accurate drainage without any demands on the installer. All you have to do is make sure the base is level.

Because the shower bases are so thin and strong, expensive joist modifications are unnecessary.

If you ever want to remodel your shower, simply remove the tile, repair the waterproofing, and lay new tile.
