In both of my bathrooms, whenever someone takes a shower, there is a few drops of water that makes their way to the unfinished basement floor below. My tubs were set on the sub-floor made of sheeting boards, so water finding it's way to the basement is easy. My question is, where is it leaking? It doesn't do this when one takes a bath, so it's not the drain. I have taken the faucet plates of and caulked with silicone several times, and there is still a leak. It's nothing major, but if the tubs had been put on the finished floor, I never would have known until there was a major problem. This must be common, because every time I watch one of those home make-over shows, the floor is always rotted out under the tub. How can I stop the leak?
