Wall Mounted Linear Floor Drain, invisible Tile Insert Cover – Backwall Return Flange Only

Upgrade your shower with the DUFR-TN Series wall mounted linear floor drain from Drains Unlimited. This tile-in drain installs flush with the wall, eliminating the need for a tile strip between the wall and the drain. It secures directly to wall framing, simplifies waterproofing, and removes the need to float the finish tile — resulting in a clean, modern shower design.
