Munsen rings and copper pipe would work. If you have access to a pipe bender then you could bend the pipe to fit the alcove. The simplest and easiest to make would just be three lengths of pipe (one on each side) with no joins... but where's the fun in that?
I'd like a horse shoe shaped rail to hang utensils on, which fits in thid alcove.
What are my best options?
Inital thought was 3 peices of copper pipe with two 90° joins. The only thing is what offsets would I go for?
