Designing Kitchens and Bathrooms - bathroom moisture damaging wood floors outside

I have an interior bathroom (no windows) with tile floors, but with hardwood floors right outside the door. The wood flooring outside the door has absorbed some water, and has some waves to it. There is an exhaust fan which blows into the bathroom, and the stone block (I don't know what you call these) below the door to draw the humidity out.

Any suggestions on how I can prevent further damage? Having a fan remove air from the room probably won't be an option for me. I thought about placing a rug there, but that could potentially worsen the situation if water gets trapped into the rug and then seeps into the floors. I do have a small dehumidifer that I sometimes run in the bathroom, but there is no way it can keep up with the stream generated from a shower.

Thanks.

wallst32,

You are not giving enough information which would help in providing a good answer.

What is in the bathroom that is causing this much water - not moisture!

Why would you have an exhaust fan blowing into the room?

Why can't an exhaust fan be installed to be vented outside or above through roof?

I have the same arrangement as you, tiled floor and hardwood outside. I do have a window but never open it and I have an exhaust fan vented through an exterior wall.

Need more facts.

Doug- Thanks for the reply. Here is some more information; let me know if you can provide some more insight.

The humidity is coming from long hot showers. My mirror is mostly or completely covered usually after a shower.

I know they make fans that take air out of the room and vent it outside. But I live in a condo and this would not be an option for me. Most people I know with houses have the same setup; fan blowing into the room. It's rare to see someone with a vent going out the roof, probably due to costs. A fan would blow into the room, to force air/humidity out under the door.

Since my bathroom is in the interior, I have no window. The only thing I could do is open the bath room door, walk across the hall, walk into a bedroom, go about 11 feet, and open a window that is almost directly alligned with the bathroom door. This will actually work if the weather outside is cold. But on warmer days, it wil not draw the humidity towards the window.

In addition to fan (which I believe is required by code now, at least in my area), I also have a ceiling register from my HVAC in the bathroom. I could also turn this on, but again, it blows air into the room. And the return register is located far away.

wallst32,

Thanks for the information.

In this case, I cannot suggest much to assist.

Long hot showers to do what you mentioned is a problem. Possibly a bigger dehumidifer is required. Leaving the door open isn't an option in most instances but relieving the moisture is a must.

Good Luck!
