I do somewhere between five to 8 bathroom remodels a year. One or two will be showers, but most are tubs. I use a rubber liner on the floor and spread mud over it to get my slope. On the walls, I really like Hardi.
In my experience, the leaks in showers are almost always at the drain. I find that most of them are brass, and have worked themselves loose with cracking over the years. Nothing to do for it but tear it all out and replace it.
In tubs, it's the edge of the tub where the tile comes together. Most of them have grout in there that has cracked and fallen out. Never grout around the tub, use caulking. White or the color of the grout is the only thing that works.
In every bathroom remodel that I've done, all that was under the tile has been two layers of sheetrock. Nothing else.
While my experience might be unique, I can tell you that the sheetrock is always dry and I've never had a problem with a leak anywhere in the tile. If it's not at the tub, then it's at a window or some homeowner modification.
I don't think grout sealer makes grout water proof, and I know it doesn't do anything for stains. From what I understand, it creates a chemical reaction with the grout to harden it. Don't put on a sealer and your grout will rub away. Add the sealer, wait a few days and it's as hard as the tile. In many cases, it's easier to break the tile then the grout!!!
