Does anyone know of a fan/light combo that can be mounted in the shower stall. I've got a wall that comes down 18" from the ceiling, separating the shower stall from the rest of the bathroom, and I'm concerned that a fan mounted in the bathroom wouldn't be very effective in venting the moist air from the shower.

Any other suggestions would be appreciated.

Fantech makes a good solution, but it may be more than you want or need: http://www.fantech-us.com/vlc.htm

I ordered the parts online from here: http://www.hvacquick.com/company.asp

With the Fantech units the fan is mounted away from the vent opening and connected with flexible duct so there is almost no fan noise. The vent/light combo uses a low voltage light so you don't have to worry about the code issues of running a 120V light above your shower.

I just installed a Fantech unit in my home and it works great. I hate loud bathroom vent fans. It may not be the right solution for you though if you cannot easily get to the space above your shower to run the appropriate duct and install the fan. They also make bathroom vent fans that install on the outside of the house to reduce noise and avoid the installation hassles.

Or, search on the web for bathroom vent fans.

Good luck!
