Like in any DIY journey, you should precisely follow well-curated instructions to ensure you build a firm foundation for your shower.

What to Know Before You Begin?

Before you begin, some precursors require your attention. It is worth investing time to assess and understand the following:

  • Strength Check: The first step is critical for avoiding structural damage in the future. Inspect to ensure your floor joists and subfloor can support the weight of the mortar, tile, and water used in a shower.
  • Outline Your Vision: Use a pencil to draw the dimensions of your shower directly onto the floor and subfloor. The sketch serves as a visual reference during the construction process.
  • Clearing the Way: Remove drywall 6 feet above the intended shower space and in its immediate vicinity. This provides sufficient room for installation.
  • Solid Support: Install 2-by-6 lumber blocks between each floor-level stud space to strengthen the shower base's structural integrity. Screw these blocks tightly together to create a solid foundation.
  • Plumbing Considerations: Redesigning the entire bathroom? It is the perfect time to inspect the plumbing conditions and move or install new plumbing lines. If you want a sauna-like experience, consider wiring for a potential steam shower during this stage.

Building a Strong Foundation

Once the foundation is laid, it's time to construct the physical structure supporting your walk-in shower.

Creating the Curb

Building a curb out of 2-by-4 lumber will define the shower's perimeter and prevent water from escaping. Stack and screw these boards together to form a well-defined edge.

Crafting the Mortar Subfloor

This layer creates an inclined foundation for optimal water drainage.

  1. Mix mortar according to product specifications and pour it into the shower area.
  2. Use level and screed blocks to create a smooth surface with a slight incline that directs water down the drain.
  3. Install the drain, keeping the top half accessible for future modifications.
  4. Allow the mortar to cure overnight, giving it enough time to firm up.

Ensuring Waterproof Protection

  • Laying the Waterproof Membrane: To construct a watertight barrier, carefully roll a PVC shower pan membrane around the base and curb.
  • Securing and folding: Nail the top edge of the membrane to the wall. To ensure a seamless seal, fold the excess material neatly into the corners and caulk them.
  • Revealing the Drain: Cut the outer layer surrounding the drain to expose it for future tile installation. Caulk the cut edges, then rebuild the drain to ensure a watertight connection.

Cement Board Installation and Reinforcement

  • Vapor Barrier: Follow building codes by placing a plastic sheet or felt paper over the wall studs to prevent moisture entry.
  • Installing Cement Board: Attach cement board panels directly to the walls, ensuring a tight fit against the mortar subfloor and curb. This provides a stable foundation for tile adhesion.
  • Caulk for Protection: To prevent water seepage, fill the spaces between the cement board and mortar bed with caulk. To attain a smooth finish, conceal exposed screw heads with caulk.

Strengthening with Expanded Metal Lathe

Reinforcement Layer: Applying a layer of expanded metal lathe over the mortar flooring will improve the shower base's integrity. Leave the drain and a small border around it uncovered to make room for tile installation.

The Final Step – Pouring Mortar

Completing the Base:

  • Leveling Up: Draw a reference line 1.5 inches above the subfloor's height around the shower's perimeter. Adjust the drain height to provide optimum drainage and a flat platform for tile installation.
  • Final Touches: Mix and pour the final mortar bed, smoothing it gently to ensure a flat, even surface suitable for tiling.
  • Curing Time: Let the mortar bed cure overnight to firm the base and prepare it for the final tiling.
