? Sorry, i'm failing to understand. You want to install a tub in an already existing shower. I got that. Isn't the shower membrane already waterproof ?

Curt...You're ahead of me, I could't get passed "install tub inside shower".

Hey guys, check out this article: https://www.houzz.com/magazine/why-you-might-want-to-put-your-tub-in-the-shower-stsetivw-vs~3149263
I want to do something similar. The article, very rightly, mentions big concerns about running the tub drain and overflow through the shower pan (you have to cut through the shower pan and it's difficult to keep watertight..); unfortunately, it doesn't give any advice or guidance on how to do this correctly.
I'm looking for help on how to do this correctly…
Make sense?

John? Where are you?

Thanks bubbasgma! I just sent john a note.

YW! Check out all his ideabooks (and blog). There are several about planning projects.

The key to this install is working with a waterproofing membrane that can be affected to the waste outlet for the tub. I make custom flashings from Noble Company's NobleSeal TS and NobleDeck for this.

Then a slit tweak to a no hub fitting and your good to go.

Properly prepared you can still preform the flood test with the fixtures or no hub fitting in place.

If you visit http://www.no-curb.com you can make a blog site donation (info top left corner) and I'll call you back with some of the design details I use for this look.

Good Luck.

This shower tub combo was part of a large barrier free shower build here in Edgemount, North Vancouver

Entire room flood tested (bathtub area and shower)



In this project we needed to flash around the tub's waste outlet and the tub filler.
