You should test your shower door to know whether water is splashing around it. In case there’s water seeping behind the door frame, then you’ll need to caulk the door frame from inside the shower area. Also, apply new caulking on the joint where the tub meets the floor.
Splash leaks occur when water escapes beyond the shower door or shower curtain. Sydney Plumbers argue that this is the most prevalent bathroom leak.
While you might assume that splash leaks are a minor thing, they can lead to extensive damage in the subfloor area where the floor meets the shower or tub.
The result will be loosening of the tiles or vinyl flooring. Even worse, your plywood subfloor may delaminate and rot, thereby demanding replacement of which may be expensive.
Signs of problems:
- Water stains around the joists or ceiling.
- Flaking or peeling paint and chalky-looking wooden finishing around the shower.
- Loose tiles or curling vinyl floor around the tub.
- Water seeping past the shower curtain.
- Mold on the bathroom floor or the wall near the shower or tub.
Finding the source of the leak:
- In case your shower area has a door, splash some water around the shower door frame and the door itself. Leaks should take around 5 minutes to appear.
- In case the shower door has a door sweep made of rubber, check whether it has some gaps. If the shower door has some rubber gaskets, also check them for gaps.
- Check whether the caulk has any gaps, especially the area where the tub or shower meets the floor.
Fixing the leak:
- If your shower has a shower area curtain instead of a door, then ensure it’s completely closed when taking a shower. Else, install a fitting splash guard.
- Ensure overlapping sliding doors close properly. Ensure the inner sliding door is as close as possible to the shower faucet.
- Replace worn out door sweeps or gaskets. Take the old door sweep or gasket with you when shopping for a replacement to get a matching size.
- Seal the leaking frame with new caulking on the frame surface inside the bathroom. Seal any gaps with caulk. Wipe any excess caulk immediately. Once the new caulk dries up, test for leaking.
- In case the old caulking on the bathroom floor has some gaps, remove it and apply new caulk.
