Hi all, today I removed some caulking from between the tile and tub on a tub/shower. It suddenly donned on me that when the water gets through the grout/cement board and goes back to the tub, how does it get back in if you have that interface caulked? Then I did some googling and found this.....
"It doesn’t need to be caulked at all. Caulking at the bottom of the tub is not a required step, it’s more aesthetic than anything else. Although it does contain more water in front of the surface of the tile, you don’t NEED it."
Even if I left little area's uncaulked (weep holes) wouldn't the water get in behind the caulk and eventually get moldy?
