Caulk by Room
Bathroom
The Room That Sees the Most Action
No room in the house demands more from its caulk than the bathroom. Constant moisture, temperature swings, soap scum, and the biological creativity of mold spores make this the toughest gig in DIY. Go 100% silicone wherever water is present. For tile-to-tile seams where flexibility isn't critical, a sanded grout caulk in a matching color is your best friend.
