I am installing a Swanstone base bedded in Structolite with cultured surround over green board.

1. Is moisture/mold resistant drywall fine for this app?

2. Would insulation in the interior and exterior walls be ok? If so, what types?

3. Do you recommend a vapor barrier? If so, what kind?

4. Does anyone water seal the studs with a product like Thompson's?

Thank You
