Individuals repairing showers should ensure the water is turned off and their work surfaces are as dry as possible. To replace a damaged shower tile, a homeowner should remove the damaged tile, leaving the underlying waterproofing undisturbed, and then install new adhesive, tile and grout. Procedures for repairing leaky shower faucets vary based on the type of faucet, but most leaks can be solved by cleaning the faucet valve and replacing any damaged parts.
To fix a dripping shower, ensure the water is off in order to avoid scalding. Next, access the shower valve by unscrewing and removing the shower handle. Remove the valve retainer, and replace any worn or misshaped parts, and free the retainer of any mineral deposits by using a wire brush.
Bathroom shower tiles may become damaged or broken over time, which can lead to moisture damage in the adjoined wall. To repair damaged tile, remove all damaged tiles and adhesive using a grout saw, chisel and masonry drill, taking care to preserve the waterproof membrane beneath the tiles. Next, apply ceramic tile adhesive to the substrate with a notched trowel or putty knife, depending on the size of the repair. Finally, push the new tile into the adhesive, grout the surrounding joints, and use waterproof caulk to repair any joints around trim or faucet fixtures.
