I need some ideas here.
We are trying to figure out how to vent our bathroom (the plumbing vents are going through the roof). How do I run an exhaust fan? We want to get the moisture and "fumes" out of the bathroom. We really don't want to use a fantastic fan, because then that would be offset from our straight line of AC's, and I think that would look kinda tacky.
Right now I am stumped. We don't want to run anything down through the bays (like a pipe with a fan), but I am not coming up with other solution. We don't have room to "pipe" the fan to the middle of the bus either (like if we installed the fantastic there) because we have limited headroom. We are trying to leave as much head room as possible....
ANY ideas???
God bless,
John

John, I used a Taylor glass hatch from the marine world in my bathroom fits flush with the roof also gives plenty of light and water tight never had a leak.

I put a small sliding window in mine.

I have just a regular 14" roof vent in our bath, and yes it's off center. I will install a Fantastic Fan someday, I don't care if it's off center or not, it'll do the job.
Just how we like it,
Paul

I just wonder if it'll refuse to work right "feeling out of place", since it'll be off-centered? ;D
John I couldn't resist, and other that I'm really no help on this one!
;D BK ;D

My Fantastic is off center. You can't tell though and its worth having. It looks fine from any angle, I don't have any negative issues with it at all.

Most motorhomes have the Fantastic Vents off center. Perhaps you ought to take a look at the next motorhome you see that has roof airs.
I assume you could probably get another 1.5" or 2" pipe to the middle of your coach. You could get one of those inline fans designed for plumbing vents. Not sure how effective it would really be.

I have off-center vents. I also have 2 vents in the kick board on my cabinets that have fans that exhaust air through two vents in the wall of the bathroom into the cabin. They are low cfm fans to keep air moving and reduce the chance of mildew.

Since you may not need as much flow as a Fantastic Fan offers anyway, maybe you could look into some marine vent fans like this one:

John,
I'll try this again, last post vanished just before I hit the post button. We have a marine grade exhaust fan in addition to a skylight that can be opened. The fan is aprox. 6" diameter, runs on 12VDC, is wired next to the light switch and is virtually flush with the interior (1/2" flange) while blending in with the other vent pipes on the roofline. In fact, ours is set so that all the vent pipes and it are huddled together making it almost indistinguishable. If I were looking to replace it, I would start with marine application exhaust vents because when you pull the handle to close it, it is virtually weather tight. Even on the highway we leave it open. (Has an internal screen) So far we haven't had any problems with it creating negative pressure in the comode plumbing since that is also piped to the rear of the bus creating even more vacuum in the black tank when on the highway. Hope this helps or gives you other ideas. We have a Fantastic fan in the kitchen and couldn't imagine anything that monstrous in the bath. But that's just us.
Good luck, Will

John,
I will try and to post a picture of our small (approximately 3" across) bathroom fan. I know they still sell them at RV places because we lost the outside cover to it a couple years back and they stocked them at a local place. It works on 12 volts and is small with a push up cover to keep out the elements. It has a screen built into it and the fan can both push and pull air. It works great and has a much smaller footprint than a fantastic fan.
It works great on our family and thats saying alot. We are NOT a bean free bus!!
Hope this helps,
Rick

12 volt vent fan from a stove hood. Small, 12 volts and vents out the side...Just a thought...Cable

John,
We put in a "Kool-O-Matic" , it runs slow with high pitch blade and is very quiet.
Moves a lot of air with the 3 speed fan on but the nice thing that we like is that it moves air even with the fan off.
The outside vent is shaped to move air out with the slightest breeze from any direction.
So when we dry camp there is an air flow without using electricity.
It needs a 14" sq hole.
It's what we have been using for the last 8 years.
