The placement of a linear drain is a major design decision that dictates how the shower floor is sloped. Unlike a traditional central drain, which requires a four-way slope, a linear drain allows for a single-plane slope. This makes it a popular choice for modern, curbless, or large-format tile installations. The drain is most commonly installed along the back wall, side wall, or at the entrance threshold. Each location changes the visual and functional design of the shower floor. When positioning the drain, the main factor to consider is where the water naturally wants to travel. The floor must be sloped down consistently toward the drain's location. For a threshold installation, the drain acts as a barrier, catching water before it can escape the shower zone, which is ideal for curbless designs. For a back-wall installation, the entire floor pitches away from the entrance. Regardless of the position, it is essential to ensure that the waterproofing membrane is properly integrated into the linear drain flange to create a watertight seal. Consult your installer on the best location to minimize the impact on existing plumbing and subfloor framing.
