Did you see capitan's DIY from Lowes? I'm impressed and plan on doing our kid's bath w/ the same. He gives details towards the bottom of the link. Robin Here is a link that might be useful: link

We are almost certainly going to do this- but are also debating on door. Thinking a sliding glass door would work fine- any water that gets in would drain to the outside anyway. Probably a lot of additional cleaning required but it'd be beautiful. Alternatively thinking vinyl outswing french doors would also work. Potentially in-glass blinds for both in case somebody is worried about privacy. The idea would be that the back wall of the shower opens to a garden with a small waterfall and pond (completely private), maybe also with an outdoor shower for post hot-tub. Thoughts on the slider? The good thing is that it's a lot of glass and already tempered. Live in NorCal so minus 20 degrees isn't an issue.

Thanks much and beautiful showers! I am confused about the thermostatic valve. Is this something that I can buy separate and have it installed in the wall so that anytime I change out the shower handle/trim/valve it will automatically be there and still be accessible if it breaks and I need to change it? I hate to have more moving parts and things to break inside the walls. LIke this (although it looks like part of this would stick out of the wall?-another hole?: https://www.amazon.com/Rozin-Thermostatic-Mixing-Temperature-Control/dp/B01FAGWKTC/ref=sr_1_3?ie=UTF8&qid=1542006430&sr=8-3&keywords=thermostatic+control+valve#customerReviews  Or does do certain valves come with it like this?: https://www.amazon.com/Hansgrohe-04231000-Thermostatic-Control-Diverter/dp/B07FDFK5SM/ref=sr_1_1_sspa?ie=UTF8&qid=1542006430&sr=8-1-spons&keywords=thermostatic+control+valve&psc=1 I was wondering, also, it sets the temp but the initial issue of being cold while the water warms up since it has to run through the pipes would still be there, right? Problem is, I have chosen champagne bronze and if I need to get the thermostatic control valve built in I think that will be hard. I'm already having a hard time finding a handheld and shower head built into the same. I might have to get a separate handheld to divert water or I'm back to the initial question of do I just push the shower head over to shoot towards the wall before I turn on the H20 or go back to the idea of moving the control valve? Here's one of the options I was looking at for a showerhead before this discuss that I might need to adjust: https://www.amazon.com/58471-CZ-PK-H2Okinetic-4-Setting-Handshower-Showerhead/dp/B009MLXJN8/ref=sr_1_2?ie=UTF8&qid=1542006748&sr=8-2&keywords=shower+head+combo+with+handheld+champagne+bronze

For two shower heads and this configuration, you'll need to put a full wall next to the toilet so you can have the shower heads across from each other. The only area that closes in is the toilet, so I think it's fine. You'll still have the long side of the shower as glass, with the window providing light to the vanity, shower, and tub where you need it.
