Why Is The Caulk Around Toilet Turning Brown? (Fixed)

Sealing the base of a toilet is highly recommended.

It’s one of the best maintenance tips a property owner can follow. Having the silicone caulk set up around the base of the toilet helps prevent leaks and/or moisture from getting through.

However, things are not always as rosy as they need to be.

This can include a situation where the caulk around the toilet starts turning brown.

If the caulk around the toilet is turning brown, this means the wax ring is damaged or leaking. It causes moisture to settle along the caulk causing it to turn brown or yellow. To fix this issue, replace the wax seal and re-caulk the toilet base.

This will take care of the issue.

It is not a pleasant sight to deal with and it should be corrected as soon as possible. If you let things fester for too long, it will create a situation where the browning gets worse.

It is also possible for the water to get through and start damaging the flooring.

This article will provide a more detailed look at what to do if the caulk around a toilet is turning brown suddenly.

To do this, two screws run along the base of the toilet. Some might have more and that’s fine.

The goal is to get to the wax ring, which is set between the toilet and the drain hole. When you take off the toilet, you will see the wax ring right away.

Start inspecting the wax ring and look for damage or leaking. It will be obvious if the caulk around the toilet is brown.

After you are fully satisfied with how the toilet is set up, you can begin to re-caulk the toilet base.

Use a 100% pure silicone caulk for the toilet base.

This will be waterproof and is going to last a lot longer than any other option on the open market.
