I am looking at installing a bathroom in my basement. The tricky issue, or at least the one I am asking about here, is that there isn't an easy way to run a vent fan. The basement is a walkout, but the bathroom would be located on the other side of the basement, so it would be difficult to run vent pipe from one end to the other. On the below grade side I'd have to drill through the foundation wall to vent out (and it is a brick face above the foundation wall).
My one thought is that the dryer vents through the concrete already...but I could foresee some problems hooking up to the existing vent...for instance blowing hot air from the dryer in to the bathroom. Is there any way to hook up to that vent and use a 1-way trap/valve/damper? If so, would this likely meet code?
