How to Repair a Leaking Shower Without Removing Tiles
A leaking shower is a common household issue, but many homeowners worry that fixing it will require ripping up tiles and carrying out a major renovation. The good news is, in most cases, you can repair a leaking shower without removing any tiles. With the right approach, you can stop leaks, protect your home from water damage, and restore your bathroom’s appearance.
Tools and materials you’ll need:
- Grout removal tool or multi-tool
- Utility knife or silicone scraper
- Grout float or applicator
- Bathroom-grade epoxy grout
- Mould-resistant silicone sealant
- Caulking gun
- Sponge and cleaning cloths
- Shower sealant solution (optional)
- Protective gloves and safety glasses
You can purchase the above items from most local Bunnings.
Step 1: Identify the Leak
First, confirm that the leak is coming from the shower rather than faulty plumbing. Run the water and carefully check for moisture around the floor edges, wall joints, and shower screen. Most leaks in tiled showers occur because grout or silicone has deteriorated, allowing water to seep through.
Step 2: Remove Old Grout and Sealant
The key to fixing leaks without removing tiles is to focus on the joints. Use a grout removal tool to scrape out cracked or damaged grout from between the tiles. For silicone, carefully cut and peel away the old sealant from edges and corners. This creates a clean surface for the repair materials to bond.
Step 3: Apply a Waterproof Sealant
Once the area is prepared, apply a high-quality epoxy grout or waterproof sealant. Epoxy grout is more durable and water-resistant than standard grout, making it ideal for showers. After re-grouting, use a mould-resistant silicone sealant to seal all edges, corners, and around fixtures such as taps and shower screens. This ensures no water can penetrate behind the tiles.
Step 4: Use a Shower Sealant Solution
For extra protection, you can apply a liquid shower sealant over the tiles and grout. These clear sealants penetrate into porous surfaces and create a waterproof barrier without altering the look of your bathroom. It’s a quick and effective way to reinforce your shower against leaks.
Step 5: Test and Maintain
Allow the grout and sealants to cure as per the manufacturer’s instructions. Once dry, test the shower to make sure no water escapes. Regularly check grout and silicone for wear, and reapply sealant when necessary to keep your shower watertight.
