Transforming a bathroom corner into a functional shower is a rewarding DIY project. This guide walks you through building a raised shower tray, complete with tiling, lighting, and enclosure. Whether you're updating a guest bath or your master suite, these steps will help you create a stylish and practical wet area.

Planning Your Raised Shower Build

Before you start, ensure you have the right tools and materials. A raised shower tray requires careful waterproofing and drainage. For inspiration, browse our home improvement collection for essential tools and fixtures.

Step 1: Demolish Old Tiling

To build a shower where none existed, first remove existing wall tiles. Use an oscillating multi-tool with a thin abrasive disc to cut through grout lines, then a flat chisel and hammer to pry tiles off. For larger areas, an electric demolition hammer speeds up the process. Work carefully to salvage tiles for reuse. Clear all debris down to the screed for a clean base.

Step 2: Install Plumbing and Framing

Create a 15 cm high threshold with a dual drainage system for both shower and toilet, connected to existing waste pipes. Pour a screed to match the shower tray height. Build a side wall from moisture-resistant plasterboard to house water supply pipes. This half-wall also screens lighting, so install a dropped ceiling with low-voltage recessed spotlights. Choose lighting that is sealed against steam.

Step 3: Fit the Shower Tray

Position the raised shower tray on the screed, ensuring proper slope toward the drain. Seal edges with silicone and connect the waste pipe. For a seamless look, consider a bathroom vanity nearby for storage. Use waterproof backer boards for any additional walls.

Step 4: Install the Shower Door

Frame the enclosure with aluminum or stainless steel profiles. Hang a hinged or sliding shower door, ensuring tight seals to prevent leaks. For a cohesive bathroom design, pair your shower with mirrors and wall decor from our collection.

Lighting and Finishing Touches

Recess low-voltage, waterproof spotlights into the dropped ceiling. Seal all gypsum fiberboard edges with silicone to block moisture. Outside the shower, add rugs for comfort and curtains for privacy. Complete the look with storage benches for towels.

FAQ

1. Can I build a raised shower tray on a concrete floor?

Yes, but you must ensure proper waterproofing and slope toward the drain. Use a screed to create the necessary gradient.

2. What type of lighting is safe for a shower?

Only use low-voltage, IP65-rated recessed spotlights. Seal all edges to prevent steam ingress. Our outdoor lighting collection offers durable, moisture-resistant options.

3. How do I waterproof the half-wall?

Apply a waterproof membrane or cement board behind the plasterboard. Seal joints with silicone and use moisture-resistant materials throughout.

4. Can I reuse old tiles?

Yes, if removed carefully with a chisel. Clean off old adhesive and reapply with fresh thinset.

5. What is the ideal height for a raised shower tray?

Typically 10–15 cm (4–6 inches) above the bathroom floor to accommodate drainage and create a subtle step.
