I am happy to hear that you are adding on to your shop. (We are ALWAYS happy to see other woodworkers expanding, I think!) I look forward to the pictures – messy or not – so we can see your progress.

Congratulations! You do such beautiful work! I can’t wait to see how you do. :)

The code is to exhaust air to the exterior , ie thru roof or exterior wall. If codes not an issue do what you want, but obviously you’ll be exhaustung the fumes to the interior of the shop or an open but vented attic!

Have fun and enjoy your expansion. As for a bathroom exhaust, I live in the country so no code problem. I vented a bathroom exhaust into a very well insulated and vented attic 20-years ago and have not had any problems. Hope this helps.

Shop expansion…oh yeah…!
When the weather is good I use a exhaust fan that I place by the window….when I fart I don’t bother to turn the fan on. If you have a finishing room then a permanent fan is good but definitely vent it outside…especially if you don’t like the smell of the finish you use. I use lacquer a lot and it definitely needs venting.

I’ve been out of the construction trade for many years now, but my $0.02 might be still be relevant here. The purpose and code requirements for venting a bathroom exhaust fan via through the roof or exterior wall is to let moisture from the bathroom escape outside. Moisture from a shower for instance that’s vented into an attic could cause moisture problems. Those problems could be mold and rot on and within the structure (roof deck, framing, and insulation). If you live in a cold climate, that moisture could freeze in the attic space as well.
You’re situation is different though because this is a finishing room and not a bathroom, so moisture isn’t a concern. But fumes from your finishes is and perhaps the reason for needing ventilation. IMO, I would vent to outside versus another part of the shop or into an attic space.
If a bathroom exhaust fan is a plausible solution for removing finishing fumes then follow guidelines on sizing. A bathroom exhaust fan sizing (I think from what I remember) is based on CFM. Base the size of the room per the CFM rating on the exhaust fan, but IMO, I would size it over and get a exhaust fan rated for a bigger space.

I use a bathroom exhaust fan installed to vent through the exterior wall when I use shellac and polyurethane
to finish projects in my downstairs workshop. I brush the finish, not spray, if you are spraying, you will have
to use one of the fans with a adequate cfm rating.

That’s great your expanding your shop. If your going to use flammable materials you may want to think about an Explosion Proof Exhaust Fan they cost more but they are a lot safer than using a bathroom fan. I would not vent into the attic I would definitely vent outside.

Hey Roger, I may be completely off base here, but I get the idea that you used the word “bathroom” simply because that is the type of fan, and not necessarily having anything to do with a bathroom per se. SO, if that is the case, it seems you could vent in any direction you wanted as long as you are venting to a place with adequate ventilation. You could even consider going through a side wall and using a dryer vent hose setup if the logistics make it feasible.

Hi Roger,
When I built my shop and small finishing room, I installed a central exhaust fan used venting multiple bathrooms in a house. It delivers a lot more CFM than a single bath fan. Also, as Jim mentioned, when considering explosion proof, I found that the main element for explosion prrof was that it did not have metal parts that could cause a spark. The central exhaust fan I found was almost all plastic so I went with it. It exhausts to the outside which is a must and does the trick in my finishing room. I made a box that holds a filter to trap particles prior to hitting the fan mounted in between the ceiling joists. I think this fan was a little over $100.

I would add that you have to take into account what it will be exhausting. If there might be dust in it, it would be best to go outside or be filtered before it is dumped inside. My 2 cents worth!!...Have a great weekend…Jim

Code is certainly important, don’t want to blow yourself or the house up.
But if you’re outside the city and its a separate structure here’s a couple of thoughts.

Instead of sucking the fumes out with a bathroom exhaust fan (explosion proof blower required) consider PUSHING outside air into the space but with an exhaust port from the room to the exterior.
That would minimize the explosive vapor issue.
I’d make sure to turn the fan on before you start finishing to establish an air flow to keep any vapors from getting to the fan motor.
You could certainly use a bathroom vent fan in that case and I’ve seen some nice little axial flow fans at Northern Tools.
And I’m thinking dryer vents for the exhaust ports. You could put more than one in different locations (high and low). You can even put one from the blower on the INSIDE of the room to keep vapors away from the motor if its off.
And while I’m in creative mode a bathroom timer would let you set it and forget it for projects that you want to leave the fan on to try/cure.

Definitely exhaust to outside. Whether or not you have code issues or location isn’t a problem, exhausting in the attic is not a good idea.

Sounds like a great project Roger. I agree with PASs, you do not wan to get in to the Long Yankee Green required to do explosion proof fans, ect. Push frash air in and let it exhaust through a few vents with back draft dampers.

That push idea of Pete’s sounds like a sensible Idea to me. I might consider something like that for my shop.

hey Roger looks like you have alot of great ideals here and what Im about to type may have already been stated…If you have perforated soffits along your eves then the easiest way to vent the exhaust fan in place of going thru the roof is to vent it out by your soffit through the attic, cut you aboard to fit inbetween your trusses or rafters were they meet the exterior wall drill a hole in the center to fit the exhaust line and if you dont have a vented soffit you can always cut out a section and add a critter screen to the exterior

hope this helps, cant wait tp see the finished shop

I’ve been hard at it for about a month now. Getting things situated a little at a time. I’m liking my extra space so far. Have a way to go to get all the little sh__ put back together.
This is all my stuff crammed in together to make room to put the walls up, and a few more of along the way pics.
Thnx for lookin. Any comments, good/bad/ugly, and/or thoughts, are all appreciated. WHEW! I’m tired.

I agree with those who told you not to exhaust into the attic.
I think the pushing of air to avoid use of an explosion proof motor is a sound suggestion if you filter the air.
Somebody may have said that if you use an exhaust fan with a motor outside of the airstream like an axial fan you could avoid the EP motor, but please check that with a vendor.
As to code I suggest you not call your room a paint booth.
I do remember seeing a very nice setup in the shop section of the site when I was borrowing ideas.
