SereneDrains Linear Shower Drain System

Upgrade your shower with SereneDrains™ linear shower drains, designed for modern bathrooms, curbless showers, and professional tile installations. This guide provides step-by-step instructions and expert tips to ensure proper installation, drainage performance, and long-term durability.

General Installation Tips

  • Linear drains with stainless steel grates are typically installed along a wall, shower entry, or threshold. They can also be installed anywhere as long as a ¼" per foot slope is maintained.
  • Always install waterproofing over a properly sloped base (¼" per foot), whether using a traditional mortar bed or surface-applied membrane.
  • Use reinforcing fabric with liquid waterproofing membranes for any gaps larger than 1/8". This is especially important at the drain flange and wall-to-floor transitions.
  • For curbless showers, position the drain parallel to the entry to maintain a smooth, level transition.
  • When installing against a wall, set the flange directly against studs or sill plate. The center of the waste pipe should be approximately 2 1/4" from the wall.
  • Account for thin-set, waterproofing, and tile thickness so the finished wall tile sits about 1/16" from the drain channel wall.
  • Install floor tile approximately 1/16" from the grate edge for easy removal and maintenance.

Step-by-Step Installation

Linear drain rough-in preparation

Step 1: Pre-slope the shower pan and install waterproofing according to the manufacturer’s instructions. Perform a leak test before proceeding.

Step 2: SereneDrains™ standard channel width is 2 3/4" (70mm). Ensure the rough opening is about 2" wider than the drain length to allow for backer board and tile thickness.

Step 3: Use a temporary 3" wide wood spacer cut to length as a placeholder. This creates an approximate 1/8" gap around the drain for flexible sealant.

Step 4: Build the mortar bed and install tile with a 1–2% slope toward the drain.

Step 5: (Tile Insert Models Only) Install tile into the drain’s insert tray.

Step 6: Remove the wood spacer, clean the cavity, and install the SereneDrains™ channel. Set it level and slightly below adjacent tile (about 1/16").
