MUST be tempered glass, plexi-glass is an absolute no, and you would need some aluminum or steel structure for a ceiling. Post a floor plan and elevation drawing of yoru bathroom for better advice.

Many Thxs will post plan at weekend.Did see this here was wondering how it was done without a ceiling structure

I do not believe it is a steam shower. The steam usually comes out of a valve about two feet off the floor. There seems to be no steam valve. It is just a free standing shower I think. Slopped ceilings are also recommended for a steam shower to help prevent condensation dripping on you like rain I believe.

Many thanks for all your input. Thinking may use the Kerdi board system seems easy to use, any views plse?

Kerdi is great for steam showers - but you need someone with experience to make sure your steam stays inside the shower and not in your walls. Steam generators are sized based on the volume of the space you are steaming, so put a glass ceiling on the shower, or a lowered (and steam proofed) soffit. As mentioned above - the ceiling must be sloped. And as Sophie mentioned, steam can ruin a house quick - so find an experienced tile person. Would not diy unless you have been doing it awhile.

Kerdi is not permeability rated for steam. Waterproofing only.

Sophie isn't Kerdi DS a vapor retardant?

Fabric doesn’t meet current 2013 adopted vapor permeability standards. .5 or less is required. Kerdi is .75.

Schuelter is selling both their ds membrane and Kerdi board as steam room compatible . Scary.

DS is steamable. Just much much harder to work with. Board just barely technically squeaks in at the wire, but there are a lot more materials out there cheaper, that do it better, and are more rigid.

Excellent advice thank you

Ok folks. Second half of 2014 TCNA changed the required perm rating from less than 1.0 for residential and less than .5 for continuous use steam showers to all steam showers must be below .5 Kerdi could not meet that rating so they came out wth Kerdi DS. The kerdi board just barely makes it. The DS membrane has a .17 rating and is extremely thick. This is one of many reasons I no longer use the Kerdi system. I did go to USG as their board and membrane are rated .08. Board is triple the density of Kerdi and no washers or patches required. The membrane is thinner than the original Kerdi and holds a crease. Custom bases in a week and much denser. Less $$$ than Kerdi. There are other systems I also would use before Kerdi. I have installed many Kerdi showers without a problem but there are much better choices to consider. IMO

chrisjmat, also consider a steam shower ceiling detail for tile would be a 2" slope per foot so the condensation does not rain on you while enjoying a relaxing steam. It will run down the side wall instead. Lots of details to consider with your design idea. Hire a PRO. No short cuts!!

Many thanks for the continued advice. Went to a tile shop who purported to have a programme for a 3 D image but the person was hopeless!! Can someone suggest a program so I can post our design wishes plse?

Pencil and paper never crashes as a design tool.

My go to always. IMO yhough you need anexpert in steam showers not a glass supplier. There are many things that need to be addressed when pumping steam into an enclosure.

Update on progress. Went to another tile shop and hit gold as the designer knew a lot about steam showers. Also recommended a contractor who came round 2 days later and straight of the bat got what I wanted and suggestions that have been commented here. Quote good as allowing me to buy the hardware.
In two minds about the plumbing fixtures. One person who put a rain shower, jets and a hand shower advised only used the hand shower! Wanted to put 2 jets in but advised not really worth it? So thinking a hand shower on a rod and perhaps a rain shower head to be used on occasions?
Appreciate views on which way to go?
Thanks

Have at last finished the project! Found an excellent contractor who knew about steam!! Pitch of the glass roof wasn't a problem just 2" in 3' no drips when sitting!! The difficult part was the glass roof, but found somebody who had done it before! Only slight problem is when starting steam bounces of the floor at start of, so that side is a tad hot but ok once up to temp.

This is a 2 sink vanity. Decided to use the existing framework and spray painted it!

Further advice sought re the grout. Have porcelain tiles and a very narrow grout line. Understand that the porcelain tiles are non porous but the grout is porous. Do I need to reseal yearly he grout? Have read some say yes others no as the grout has to breath? Advice please on what product to use if I should seal it?
Many thanks

Chrisjmat: Would you mind sharing which vapor proofing system was used on your steam shower? It looks great - hope you are enjoying it!

Chrisjmat: I have the same exact plan. Wanted to know how shower especially glass ceiling holding up.

Sorry didn’t see this to now. So the vapor system was standard shower boards. The grout lines are very thin and I use 511 Porous Plus sealer, which I reapply yearly. No problems so far!

The glass is channeled into 2 walls and a stainless strap secures the other 2 glass to glass sides!

I use a squeezee to wipe the glass after use, so far glass I’d pretty clear.

if you want more information, happy to help, love the steam shower, certainly would never be without it!

Hi Chrisjmat,

Your steam room pictures look very nice. What city are you in? Can you share your glass ceiling contractor contact info. Thx.

What type of glass did you use?
