What kind of caulk should I use around my bathtub?
I just caulked my shower last night. I used GE Silicone II caulk from Home Depot. I read up on this a little before picking out what kind I needed. From what I can tell, silicone caulk is good for bathrooms because:


It's permanently waterproof
It doesn't crack or shrink


Another factor which may play into your choice of caulk could be whether or not it's paintable, but the most important factor for a bathroom is going to be waterproof/mold proof.
