How to Build a Shower Pan on Plywood Floor: A Step-by-Step Guide

Building a shower pan on a plywood floor can be a challenging but rewarding project. It allows you to create a custom shower space that perfectly fits your bathroom and needs. This guide will walk you through the process step-by-step, ensuring a successful and leak-proof shower pan.

Materials You'll Need:

  • Plywood: ¼" or ½" thick plywood, depending on the subfloor's strength and the weight of the shower pan.
  • Shower pan liner: A pre-molded shower pan liner or a waterproof membrane like Schluter Kerdi.
  • Mortar bed: Thin-set mortar for attaching the liner and tile.
  • Tile: Choose your desired tile for the shower floor.
  • Grout: Matching grout for the tile.
  • Drainage kit: A drain assembly kit that includes a drain pipe, strainer, and a flange.
  • Waterproofing sealant: Liquid or tape sealant for waterproofing the perimeter of the pan.
  • Tools: Level, tape measure, circular saw, utility knife, trowel, mixing bucket, safety glasses, gloves, and a respirator.

Step-by-Step Instructions:

  1. Prepare the Subfloor:
    • Ensure the plywood subfloor is level and sturdy.
    • Replace any damaged or rotted sections.
    • Use screws or nails to secure the plywood to the joists.
  2. Install the Drain:
    • Locate and mark the drain position.
    • Cut the drain hole in the plywood using a circular saw.
    • Install the drain flange and ensure it is level.
  3. Install the Shower Pan Liner:
    • Pre-molded liner: Cut the liner to fit the shower area and adhere it to the plywood using construction adhesive.
    • Waterproofing membrane: Apply the membrane to the entire shower area, overlapping the seams by at least 2 inches. Use a waterproof sealant to secure the membrane to the plywood.
  4. Create a Mortar Bed:
    • Mix the thin-set mortar according to the manufacturer's instructions.
    • Spread a thin layer of mortar over the shower pan liner, ensuring it is even and level.
    • Place the drain assembly into the mortar bed.
  5. Install the Tile:
    • Use a trowel to spread a thin layer of mortar on the tile back.
    • Carefully place the tile on the mortar bed, pressing down firmly.
    • Continue tiling the shower floor, ensuring the tiles are level and even.
  6. Apply Grout:
    • Once the mortar has set, apply grout between the tiles.
    • Use a grout float to spread the grout evenly.
    • Clean up any excess grout with a damp sponge.
  7. Seal the Edges:
    • Use a waterproof sealant to seal the perimeter of the shower pan, ensuring a watertight seal.

Tips and Considerations:

  • Waterproof the entire shower area: Ensure that the walls, curb, and floor are properly waterproofed to prevent leaks.
  • Use quality materials: Invest in high-quality plywood, liner, mortar, and tile for a long-lasting shower pan.
  • Follow the manufacturer's instructions: Always read and follow the instructions provided with the materials you are using.
  • Get help if needed: If you are not comfortable with any part of this process, consult a professional contractor.

Conclusion:

Building a shower pan on a plywood floor is a challenging but achievable project that can significantly improve your bathroom. By following these steps and using quality materials, you can create a durable, waterproof, and beautiful shower space that will last for years to come.
