In the end, you will likely have to replace your tiles. Hence, to save yourself from such a costly job and extra effort, it’s best if you seal the grout in your shower tile.

All of this is especially true for shower tiles because they are exposed to the most moisture compared to other parts of the bathroom. By sealing shower tile grout, you will be blocking the moisture from being absorbed by the grout, making this an absolutely essential step in maintaining your tiles.

Which Shower Tiles Don’t Need to Be Sealed

There are some exceptions to the rule depending on the type of tiles in your bathroom. That is, some tiles require sealant while others don’t.
