Re: Grout Before Installing Tub?
What kind of tub is it?
Generally, a fiberglass or resin tub isn't grouted where it meets the tile, because flexing of the tub would crack the grout line and allow for water entry.
On the other hand, steel and cast iron tubs can be grouted since they are rigid.
When you set the tub, place some concrete mix underneath the tub. This will provide additional support to the tub so it's not entirely supported by the tub deck. This will also give it a more solid "feel" and help prevent flexing of the tub deck, which could crack the tile.
