Wall-Adjacent Linear Drains, Polished Square Design, Backwall Return Flange – Drains Unlimited

These stainless-steel wall linear drains fit flush along the wall, creating a clean and modern look. Ideal for enhancing drainage in contemporary showers, they also add a stylish, refined touch. The wall-mounted design secures directly to the wall frame, eliminating the need for a tile strip between the wall and the drain. This installation simplifies waterproofing and delivers a seamless, professional finish.

Important Note:

The Backwall Return Flange Only is designed for installation along one shower wall and does not extend fully to the two adjacent walls. This allows for flexible placement anywhere along the back wall, regardless of length.
