   I say take the shortest route.

   Hope this helps.

   *If you can find a suitably effective and quiet wall vent fan, go for it. Wasn't an option for me due to problems fishing the wire through an exterior wall filled with blown cellulose.

   *And you'll want a vent with a closure that works in a vertical position (when the duct is horizontal). A lot of them only work when pointing straight up. But otherwise, yeah, shorter is better. -David

   I had to fabricate my own elbow to exit thru the wall on 2x4 wall framing because of the tight space--actually used an old fire extinguisher body and pop riveted and siliconed the joints to create a 3" heavy-wall duct with integral 90 degree bend.I used a standard dryer vent louver type cover on home exterior(vinyl). good luck!

   There's obviously less duct involved with going thru the outside wall than thru the attic. But are there any problems with going out the wall with a bath vent?

   TIA

   If the soffit is vented, always through the roof ..

   I went with a remote unit mounted in the attic, it allows multiple vents and is the quietest and most efficient I've owned. I ran vents to a few closets, too.

   Why would you vent a closet? Humidity?

   Maybe he just likes wasting money by venting heated air. That is one of the oddest things I've ever heard.Also, I cannot understand why if the soffits are vented, you would go through the roof. I always believe the fewest number of holes in a roof, the better, no matter what you do with the flashing. Just do the shortest run to the least visible area.

   "I cannot understand why if the soffits are vented, you would go through the roof."

   I've seen the steamy, moisture laden air come out the vent and then get drafted right up into the soffit vent. Causes some nasty rot & mold issues in the soffit and attic space.

   I like to avoid adding a hole in the roof too but if I have to vent thru a soffit I block the soffit vents for 4-5 feet on either side of the bath vent. Not ideal, but better.

   Good point. I knew about that, just wasn't thinking of it at the time. I also think that regardless of the venting, you need to watch the placement and make sure there is decent cross ventilation so the moisture air leaves with a light breeze.thanks for the correction.

   I have a closet with a fan, but that's only because it used to be a bathroom.

   I guess I'll have to qualify my closet venting, even though some may still think I'm nuts. Outskirts of a small Maine village. Long winters. Solar oriented ranch. Heats itself in the day if temps are above zero. I use a wood stove at night and throughout cold periods. Inside temps stay in the upper 70's. No need for air conditioning in the summer, windows are open, Sometimes I put one more log on the fire than I should and widows get opened in less cold months.I found that closets can get stale. Solid doors stay closed up for long periods along with full racks and shelves. I had some leather goods get a little green. Rather than leaving doors open, I put in 4" round vents, a 6" to the bath. When ever someone turns on the bath fan, it also vents a couple of closets. My daughters are grown so the fan isn't on very long or often. Energy loss isn't an issue for me. All exterior surfaces of the house have 1" extruded polystyrene sheets under the drywall, 6" fiberglass walls, 18" in the ceiling, tripple glazed windows with fitted window quilts. Not many leaks so I need a few. I'll run the fan when cleaning the same as I run the air scrubber in the shop. I think it has made the closets a bit fresher but I don't keep my ball glove down in the far corner anymore. The remote fan unit works much better than any other bath vent or combo unit I've used. If mounted well, you don't hear the motor, just a faint hum through the duct in the bath where it's closest. You can hear the air move through the vents, it's not silent but about 1/5 the noise of an in the room unit. Very little steam in the bath after a shower and that is soon removed. Quiet, efficient and surpassing four other units I have had in the same bath. I think it will be the last necessary replacement.Beat it to fit / Paint it to match

   My old ceiling fan is noisy and lets cold air in during the winter. I was thinking of a through the wall replacement, but maybe the remote like yours would be a better option. I hate the noise of the fan, but it does remind me to turn it off.

   It's my understanding that those remote fans vent ALL of connected rooms not just the ONE you are in. I just installed a nice thru the wall unit from Panasonic but I would not want it on the front of my house
