Expanded polystyrene base

Choosing the right custom shower base for a bathroom remodeling project can be tough. The options are many – the right selection for you may not be obvious.

This base is 100% waterproof base, available in standard and custom shower designs, made in one piece with no seams, and is light and quick to install.


  • 100% waterproof polystyrene base eliminates the potential of future water leaks and worries about mold/mildew.
  • Reduced installation time and labor costs– takes less than 30 minutes to install 1. Trowel out common modified latex thin-set 2. Place a bead of silicone around the drain body 3. Install the pre-designed and pre-slopped pan.
  • Choose your drain location– You won’t have to spend extra money to rework your plumbing to accommodate a pre-determined drain location – we put it where it works best for you.
  • Custom base for non-standard sizes and walk in and roll in showers– design for any size or wall shape (straight, rounded or angled walls) both with or without (barrier free entry) a curb.
  • Seamless Design
  • Wall board is installed inside the base to eliminate leakage.
  • Lower cost than a custom designed solid surface base.
  • Recessed soap dish, shampoo caddy, shower and bench seats available for a complete system.
