I posted this in heating and a/c but that was wrong so I think thiss may be the right forum....I have an old wall rectangle bathroom exhaust fan that I need to replace. The bathroom has melamine walls so I can not use a different size and leave a hole as I could not match it up. It is not a large bathroom and it looks like the fan is only on the bottom of the rectangle. The approximate size of the the outside of the fan (around the grille) is 11x9. Does anyone know where I could get a fan to fit those dimensions. It seems everything is square or round now and I think an 11" square would be too much for the bathroom.

Someone somewhere must sell older models of fans. I just can't find them. Thank you.
