This wine rack could fit snugly under your island top overhang. I put felt on the bottom and it is finished on all sides so that it can be moved to accommodate more seating.
Dimensions: This wine rack is 34" high by 22" wide by 14" deep. It is solid 5/8" thick material throughout, even the drawer boxes! The drawer slides are top of the line "BLUM" full extension Tandem.
