Have an existing bath van whose specs state the dimensions are 14.75 x 7.875 x 5.625 inches, a NuTone 668RP 70 CFM.
Looking to replace it with a higher CFM fan, don't need the light or a heater combo with the unit. But would prefer minimizing cutting & patching ceiling drywall for a new unit sized differently. More ok with cutting bigger length and/or width needed which doesn't require patching back hole/gap on the other dimension (length or width).
Any suggestions for a similarly dimension sized fan (in terms of exact size or ratio (i.e. more rectangular than square)) with higher CFM?
Or should I just deal with picking any desirable alternative fan regardless of size (assuming fits framing & ducting) & just patch up drywall?
I did some online search but didn't seem to find much option for similar dimension sizing, or maybe I haven't looked hard enough.
