8 months ago I had my bathrooms redone. Floors and walls around tub were done with new tile. The shampoo inserts in each bathroom have grout that is cracking. They have been out once already to put in some silicone grout.
They sre starting to crack again. They didn't use silicone grout between the tub and wall. House is appx 25 years old. I am not sure if they supported the old tub or not.
Is this from settling of the house, poor support of tub, poor grouting, or even the structure under wall done poorly? Can I even tell that?
