There isn't much space under the bathroom sink in my Cedar Creek 36CKTS for large bath, hand towels and wash cloths. After searching all local stores and finding nothing I finally hit on a web site called faucetdirect.com. It didn't take long to find what I was looking for. I opted for the 2 guest model. They also have 3 and 4 guest models.

I used 1/4" plywood behind the rack to stiffen the wall.
