Building code window above a bathtub
I 'want' to have a window above the tub shower but building inspector says NO window. Does anyone 'know' of an building code approved window for above tub use??
Tempered glass maybe? Has anyone had a window above tub and been approved ?
My opinion is baths are too dark without some daylight. Inspector says turn on the light.
Any possible solutions to this dilema anyone can think of? Tub covers entire exterior wall here, no other space. Its a cheap rental, does one of those skylights or domes make sense? Leakproof??

I once hear that Glass block would work, but those are not cheap.

Interesting question. I personally don't like windows in tub area when that tub also has a shower, due to issues I have seen with rotting of the window sill from the shower water standing on the sill area.
Tempered glass should be permitted, since this is what a glass shower door would have.
I have to wonder about the reasoning that the building inspector is using here: Why isn't that window allowed? The answer to that would open up possibilities.
One other thing that must be mentioned. When a bathroom does not have a window, an exhaust fan is required to be installed to let the steam and moisture out. So be prepared to need one of these.


Perhaps it has something to do with the tub enclosure covering the entire wall? We have windows above our bath and shower in our home. Not sure what the big deal is. Where is this?

I see no reason why a code inspector wouldn't allow a window above a tub or shower. As others said, it must be tempered, but other than that, I don't see why there would be any issue.
I would recommend asking the inspector to tell which particular code this would be violating...I'd be surprised if it actually existed...

What kind of mood was your inspector in that day? I believe what is required is laminated glass, so that when it breaks, it flakes of in small crystal type pieces and will stick tothe lamination between the glass.
That what the picture window had to be that I put a few inches above the jacuzzi (with blinds, lol).
I would suggest calling your local building trade association, like the area Home Builders Association that contractors belong to. They might knowin the office or ask for a member contractor who builds upscale homes and then ask him. If they have been allowed and recently built (withing a few years) get the address. Then ask the building regulations office (avoid that inspector if possible) and get an answer. After you are armed with an example and a date that was good for such installation, then bring it up with your inspector. Most likely since he said no and you proved him wrong, he will probably be in a bad mood at that time, but he'll live through it. Get your ducks in a row before you confront any inspector! And, it depends on how tactful you are too. Good luck!

They used to build bathrooms like this all of the time. I spend a lot of my bathroom rehab budgets trying to fix their stupid idea. If you put it up high and it is a smoke, tempered, picture window then I guess it is okay.
Anything else you are looking for trouble. We put glass block in to repalce the old ones and even the advanced glue type block windows mold.
If you want a window to vent the room, get a bath fan.
If you want a window for natural light, get a skylight or a solar tube. This is more private and makes you feel like you are outside instead of on display (even if it is a shadow).
