Hello Paddy. Thank you for your recent inquiry with The Home Depot. We do not have a 12 in. W option but it can be special ordered through your local store. We appreciate your business and look forward to serving you in the future.
Ours fit just fine. Be sure to use a bottle to determine where to put the center lattice piece.
Unfinished isn't available at this point.
The product is not painted on back. You can paint by yourself.
3.5" by 3.5"
I think it could, with some gentle sanding and a quality high end primer applied first...It would def take some time but would be worth it I think, to match your new painted cabinets...We put up this wine rack, and luckily it matched our newly painted cabinets perfectly.
It can hold up to approximately 16 wine bottles.
