40-Inch Wall-Adjacent Linear Drain, Polished Square Design, Backwall Return Flange, Drains Unlimited

Wall-Line Linear Drains: Premium stainless steel polished linear drains designed for seamless wall integration. These drains install flush with the wall, creating a sleek, uninterrupted finish that complements minimalist and modern shower designs. Ideal for efficient water drainage, they offer both functionality and a refined aesthetic.

The DUFR Series wall-adjacent linear drains combine sleek aesthetics with the functionality of close wall installation. Featuring an innovative wall-mounted design, they eliminate the strip of tile between the back wall and drain, simplifying waterproofing and creating a seamless aesthetic.

Important Note:

The Backwall Return Flange Only is designed for installation along one side of the shower wall, without fully extending across the full wall length to the two adjacent walls. This makes it perfect for placement anywhere along the wall, regardless of its length.
