In this article we will handle the step by step process for you to take in order to stop water from coming under your sliding shower door.

How To Stop Water Splashing Under Sliding Shower Door

Find Location Of The Leak

This is the first thing to do because the shower doors are meant to prevent water from splashing outside the shower. More importantly, this is to make sure we do not just cover a crack instead of getting the root of the problem.

You should open the shower and let it run so that you can observe where the water is actually leaking from.

You should also check whether the caulk that was installed is actually intact or it has worn out so that you can remove it and apply afresh.

Lastly, check whether the sliding door was installed properly. If it was installed backwards you will need to unscrew and install it properly to solve the leak

Apply Silicone Caulk

The next thing to do is to apply the high quality silicone caulk to the outside of the sliding shower door.

Make sure the silicone caulk is waterproof so that you create a watertight seal to avoid water seeping under the shower door.

In addition, a quality one will last longer so you can forget this issue of water splashing under the sliding shower door.

Pro Tips

You must not apply silicone caulk on the inside of the shower door. Otherwise it beats the purpose of the silicone caulk. It is meant to prevent water from going outside the shower and not retain it inside.

Do not also seal the weep holes. The weep holes are there to ensure any excess moisture is released through them.

If you make the mistake of sealing the weep holes. Then excess moisture must find a way out through either the window or drywall.

Spread The Silicone Caulk

You will then proceed to spread the silicone caulk using a caulking tool or your fingers. This is to ensure you get a smooth clean finish. Otherwise it may end up lumpy and uneven which is unsightly.

You can use windex to smooth the caulk.

Take your time in this step of the process. Be slow but sure because we want the seal to be applied properly and well.

Leave The Silicone Caulk To Cure

Finally once the silicone has been spread, it will dry up quickly. However, the silicone will cure after 24 hours.

This means you must not use the shower before the silicone cures. Otherwise this will affect its effectiveness later.

Once a day has passed you can now test whether the door was sealed properly. If you followed all the advice we have provided we are sure the problem will be solved.

Final Words

When you discover water is splashing under the sliding shower door. You must act quickly to investigate and fix the issue.

In most cases, water splashing under shower door is due to the seal being broken. To fix it you need to get a high grade waterproof silicone caulk to apply on the outside of the sliding shower door.

Once you have identified the source of the leak, apply the silicone caulk on the outside and not inside. Do not also apply silicone on the weep holes as they are meant to let excess moisture out.

Lastly, spread the caulk using a caulking tool and let the silicone cure for 24 hours before you use the shower again.
