Unlike a WetBase Standard that has a square shaped drain the WetBase Linear has an oblong (linear) drain that runs along most of the edge of the WetBase.  The drain cover can be reversed on the WetBase Linear to allow the cover to be tiled to match the rest of the floor. A linear Wetbase may be best where joists present an obstacle to drainage because the water can be drained from any one of three locations along the length of the drain. It may also be chosen for its appearance and fit with the style of the rest of the room.
