Square Drains

A tileable square shower drain uses a removable insert designed to receive compatible tile so much of the drain coordinates with the surrounding shower floor. Water enters through openings around the tiled insert. Tile thickness, setting material, insert depth, adjustment range, and compatibility with the underlying drain assembly should be verified.

A tileable drain incorporates compatible tile into its removable cover for a more integrated appearance, while a grate-style drain leaves a finished cover with drainage openings visible. Both direct water into the same basic drainage assembly, but available dimensions, adjustment methods, finishes, and compatibility vary by drain system.

Square drains are commonly used in tiled showers, mud bed showers, foam shower systems, bonded waterproofing assemblies, wet rooms, and properly designed curbless showers. The drain must be compatible with the specific shower construction, waterproofing method, plumbing configuration, and floor slope used for the installation.

Square drains can be used in properly designed curbless shower systems. As point drains, they commonly require the surrounding floor to slope toward the drain from multiple directions. Floor elevation, waterproofing, slope, plumbing, entry transitions, and water containment must all be coordinated to create the complete curbless assembly.

Compatible square drains can use bonding flanges, flashing components, or other specified connections to integrate with the shower waterproofing layer. The exact method depends on the drain and waterproofing system. Drain bodies, membranes, flashing, sealants, and related components should be specifically approved or designed for use together.

Drain risers and height adjustment components help position a compatible drain grate or tileable insert relative to the finished shower floor. They can accommodate differences in tile thickness, setting materials, and floor assembly dimensions. Available adjustment ranges vary, so the components must match the specific drain system.

A square shower drain can be centered or offset when permitted by the shower design, plumbing, base, and waterproofing system. Changing the drain location affects the dimensions and slopes of the surrounding floor planes, so its position should be established before constructing the shower base and planning the tile layout.

Start with the shower construction, waterproofing system, plumbing configuration, and intended drain location. Then consider drain and outlet dimensions, tile thickness, floor slope, required height adjustment, and whether you prefer a tileable insert or exposed grate. Select compatible drain components designed for the complete shower assembly.
