Scott's Master Bathroom Remodel

I'm just starting my bathroom remodel, so I figured, why not start a new thread.

I had my first question answered (attaching CBU to the subfloor), so now on to my second.

The back wall of my bathroom is a 3 walled alcove that is 123" wide by 44" deep. I'm planning on putting a 60" tub on the left and a 38" X 44" shower on the right. I planning a transition from the tub deck (19" tall) into what is the short left wall of the shower. I want to put a seamless glass wall on top of the tub deck to form the left side of the shower, but I'm worried about leaks. How would I prevent leaks from penetrating my tub deck? Also, is it even possible to move the glass wall left of the tub/shower wall to create a shower seat? I'm planning on a granite tub top if that makes any difference.

thanks in advance,
scott

Because then we lose the history of the project, Scott. Just keep all the project questions here so folks can see what's been previously asked and answered.

Simply by not making any fastener penetrations anywhere on the horizontal portions of your structure. Ever.

Have no idea. You'll need to attach a picher or provide more description of what you have in mind. We like pichers.

My opinion; worth price charged.

I agree with CX,

no penetrations at all!

If the glass partition is positioned correctly so that the water that does not hit the deck surface at all, then thats the best way to prevent leaks.

But here's another thought I had...............

Perhaps you can make a joint in the granite deck surface *UNDER* the glass partion in order to cant the intended seat surface down towards the shower floor?

That silicone sealant they use is very resiliant material,,

Good luck!

CX - My intention of starting a thread for my project was so I could put all my questions in one place... sorry for the confusion.

As requested, I'm attaching a picture of what I would like to do.

I'm worried about leaks through the tub deck if I put the glass wall in position A or position B.

1. I understand why I shouldn't make any penetrations on horizontal surfaces, but what's to stop the "backflow" of water?
2. Do I need to build up a slope on the tub deck?
3. Should the shower pan membrane extend all the way under the shower glass?
4. Does the shower pan membrane need to be a continuous piece or can I overlap it on the short vertical wall?

thanks for all your help,
scott

Is that an undermount tub or a drop in?

I agree that a joint under the glass to allow the seat to slope to the shower is a good idea. This project sounds like a good application for Kerdi.

1. Don't worry about it. The horizontal portion will slope to the shower drain.

2. All horizontal surfaces in the wet area must slope to the drain.

3. At least.

4. Correctly done, it could overlap. The top portion is the problem area as it must be waterproofed without fastener penetrations of any kind.

I agree with Injineer Bob that yours is an excellent application for a bonded waterproof membrane system such as Schluter Kerdi.

My opinion; worth price charged.
