Can You Use Grout Instead of Caulk for Toilet Installation?

To prevent unpleasant odors from the toilet, it is generally necessary to apply sealant at the bottom of the toilet. Now, let’s take a look at whether it’s acceptable to use tile grout instead of sealant for the toilet.

一、Can you use tile grout directly without sealant at the bottom of the toilet

No, you cannot. When applying sealant at the bottom of the toilet, you should use silicone sealant, not tile grout. This is because the main components and properties of the two are quite different. While tile grout does possess a certain level of adhesion and is visually appealing, its adhesive capacity is lower than that of silicone sealant. Additionally, tile grout cannot be submerged in water for long periods. Given that bathrooms tend to have high humidity levels, over time, tile grout is likely to crack and fall off.

If you need to apply sealant at the bottom of the toilet, it is best to use silicone sealant with good anti-mold properties. To ensure water resistance and anti-mold effects, you can also apply a waterproof sticker over the silicone sealant after application to effectively prevent mold and discoloration.

二、How to deal with mold on sealant at the bottom of the toilet

1、If the mold on the silicone sealant is not too severe, you can first apply some toilet cleaner to the affected area, wait for a while, and then scrub it with an old toothbrush. Finally, rinse it with clean water.

2、If you don’t have toilet cleaner at home, you can soak a cloth in bleach and place it over the moldy area, leaving it overnight. The next day, use the cloth to wipe the area clean.

3、If the mold is very severe, you should completely remove the old silicone sealant at the bottom of the toilet and reapply new silicone sealant to prevent any displacement or unpleasant odors.
