Tools required to fix a leaky shower:

Turn off the water going to your shower. Find your shutoff valve and turn it all the way to the right. Flip the shower tap on and off to ensure that no water comes out.


If your shower came with a plug, put that in the drain now, or cover the drain with an old rag. This prevents any screws from falling into the drain, something that has derailed many home repair projects.


Take off the shower handles by removing all of the attached screws. Sometimes, these screws are located behind a cap, and you may need to pry off these caps with a Flathead screwdriver in order to continue.


Once all of the parts have been removed, you will likely find a damaged washer attached to the small pole on which the shower tap sits. Remove it and find a new one of the same size. If it helps, bring the damaged washer to the hardware store with you to compare sizes.

If there isn’t a washer beneath your shower tap, it’s okay, because we’ll be adding a new one anyway. Ideally, you want your washer to be only slightly larger than the central post.


Once you’ve found a new washer, coat the back of it with rubber spray sealer. This forms a powerful waterproof seal that will prevent your shower tap from leaking for a very long time. Don’t worry if you plug the hole in the middle of the washer, as you can simply cut it out in order to fit snugly around the central pole.


Reassemble the shower faucet and turn the water back on. Test the tap to make sure that it no longer leaks.

Other leaky shower problems

A leaky shower can be caused by more than just a tap problem. There may also be issues with pipes behind the wall, worn sealant around the edges, and other issues. Fortunately, these can all easily be fixed with rubber spray sealer. Simply point it at the place you want to seal and let the liquid rubber fly. It’s that easy.
