Mounting a ceiling bathroom fan in a wall?

Hello all.

I have a crappy old Broan bathroom fan that sounds like a jumbo jet taking off. It is wall mounted, not ceiling mounted. I have been looking for a replacement fan that would fit but it is very hard to find the same exact size.

The size of my fan is 8 x 8.25 x 5.75
This is the only decent and quiet fan that i've found fitting my mount size.

However I found out that that model cannot be wall mounted, only ceiling mount. That was confirmed by the customer support. This leaves me without any other options, as the Broan fan at home depot is loud at 6.0 sones. What i was wondering is could I still mount that Delta Breez fan in a wall? Would I be taking a risk by doing that?

You could try getting the information from the fan motor and simply replace the motor. Otherwise you are pretty much stuck with abandoning the existing fan and putting a new one in the ceiling, or having some patch work to do after installing a new thru-wall fan.

edit: even if you could/would mount the fan in the wall, the fan you posted won't work the way you are thinking

1) The fan is too deep to fit in a 2x4 wall
2) you would have to patch the outside siding/brick
3) you would have to run a new duct from the fan's port which is on the side of the fan

You may also be able to use a 12 vac or 24 vac "muffin" fan.

I put one of these (Fantech) in my master bath with two grills. They are fabulously quiet, can barely tell they are on. Then just drywall over the old fan location.

If you are looking for a through-the-wall fan, this one may work

If you are looking for a wall mount fan that has a duct, you can try this one:

You will likely have to enlarge your opening, but that is pretty easy.

Panasonic fans are very quiet. Use Google shopping and you can find a good price.
