Any upgrade replacement options for Bath Exhaust Nutone 696N-B? I only found an option to replace the motor with the same 4.0 noise level (Part:Broan-NuTone C350BN Replacement Motor/Wheel)
I would prefer to replace it with a sleeker look however I am not looking to replace the housing. (Note this is the "B" version and not the "R-02" etc.; those have an upgrade kit made the manufacture)
For starters Call the company and see if they have anything as the same fit for the one you have. Secondly, you can change the motor like you mentioned.
As well, they sell covers, which can replace an old looking cover if you like.
I'm not sure what you're trying to do. But if you're looking to get a whole new unit, then yeah, you're going to have to rip out the old one. If it's an attic where there's crawl space, it should be pretty easy to swap out.
