Not sure if this is in the right subforum, but the moderator can move the thread if needed
We have a bathtub that is tiled, with a small shelf on the back for storing shampoo, shower gel, bath toys, etc.
Now after five years of use, the grout placed between the bathtub (the enamel) and the tiles on the shelf has become crumbly and unsightly. Can I replace the grout with silicone instead?
