How to Seal an Unused Bathroom Toilet

If the toilet opening in the bathroom is no longer needed, it should be sealed to prevent any impact on future use. Here’s how to seal an unused toilet opening:

How to Seal an Unused Toilet Opening：

1、If you want to seal the drainage pipe as well, you can break the squat toilet and then stuff some newspaper into the drainage opening, ensuring it is filled to a certain depth. Next, use a leak-proof sealant to perform the sealing work. After that, apply cement mortar to smooth it out, making sure it is level with the floor.

2、If you want to keep the toilet opening flat for future installation of a toilet, you need to break the squat toilet first, then measure the diameter of the drainage pipe to check if it's DN110, DN75, or another size. Use a suitable connecting water pipe for this work. After handling this, seal the area around the drainage opening with a leak-proof sealant and smooth it out with cement mortar.

3、If the distance from the drainage pipe to the wall differs from the distance to the toilet outlet, it is necessary to add an elbow joint during the water pipe connection for adjustment. Once that is done, seal it with a leak-proof sealant and smooth it out with cement mortar.

What to Keep in Mind When Installing a New Toilet：

1、Before installing the toilet, it is essential to clean the drainage pipeline thoroughly and check for any waste paper or mud inside. If there are any, clean them up before starting the installation to prevent future blockages in the drainage pipe that could affect normal use.

2、Pay attention to checking the anti-siphon trap of the toilet to see if it has a glazed design. If not, it is very likely to trap dirt and lead to blockages over time. Additionally, the toilet you choose must have complete accessories and should not have issues such as incomplete glazing or pinholes.

In summary：this is how to seal an unused toilet opening and what to consider when choosing a toilet. Is everyone clear on this? Installing and using a toilet is very important; any problems can affect its future use.
