A leaking shower enclosure can cause damage to your sub-flooring, and it can even lead to water damage in the rooms situated below the bathroom. If you suspect your shower is leaking, there are a few things you can do to solve the problem. For more serious leak issues, you may need to seek professional plumbing repairs.
Look For Holes In Between Tiles
If the grout surrounding the tiles in your shower has holes in it, this can lead to water seeping into the backer board and the drywall behind it. If you are handy with home repairs, you can re-grout the tiles, or you can call a contractor to handle this issue for you. A licensed plumber who also handles tile replacement can look for other signs of trouble while re-grouting your tiles.
Check The Door Seals
Over time, the rubber seals on your shower doors can become damaged. This can lead to water escaping the shower enclosure and leaking onto your floors. Use a flashlight to inspect for small holes, or place several towels on the floor and run the shower. You may be able to see exactly where the water is leaking from, and if it is the door seals, you can replace them with seals found at your local hardware store. For frameless shower doors, you'll want to choose a clear vinyl seal that prevents leaks without taking away from the seamless look of your shower enclosure.
Inspect The Plastic Tray
If your shower has a plastic tray at the bottom, inspect it for cracks or leaks. These trays are sometimes found in bathroom basements or smaller shower enclosures. The plastic can become cracked or split over time, and even with the proper sub-flooring, water from your shower can begin to seep into the space below. One sign that water is damaging the area directly below your shower is wet or damp spots on the ceiling below the bathroom. It's a good idea to inspect the tray regularly, particularly if you have an older home. The tray can be quickly replaced by a plumber, and he or she can also help you to repair any other leaks or damage in the shower area.
If you suspect your shower is leaking, whether it's from the tiles, door, or plastic tray, work to correct the problem as quickly as possible. This can prevent further damage to your home as well as mold and mildew growth.
