Efficient shower stall design: Airflow?
So I’m kicking around ideas for efficient shower designs. Our master bath will have a shower stall that is recessed with three tile walls, and one glass wall with a glass door panel more or less flush with the side of the bathroom.
The glass wall will have three parts; two stationary panels and a door in the middle.
I would like to have the stationary panels go floor to ceiling and have the door go very close to the ceiling in an effort to reduce the amount of airflow through the shower. This should reduce cold air drafting and make for a more comfortable shower for a given water temperature.
Does anyone have any advise on how much area should be left open at the top of the shower? I’m planning a ventilation return to be located in the shower near the ceiling, so there should be a steady slow flow of fresh air coming in, but I’d like to keep from letting any hot steamy air out. I also don’t want it to get like a sauna and be hard to breathe.
Searching the web only led to designs suggesting the shower should be sealed completely, which I’m not a fan of. I’d like the ventilation return to pull air through the shower to dry it out after use.
