Linear shower drains aren't the only game in town. Also known as channel drains they have been growing in popularity and now are more competitively priced. With numerous sizes and outlet locations they can fit the existing needs during a remodel. Tile-in covers can reduce the visibility of a large drain and because you only need to slope in one direction a lot less tiles need to be cut. Some great brands are: Quick drain, Infinity Drain, FreeStyle and Aquabocci
