Hi, I am looking for some help. We are building an outside patio and are looking to add a fire bowl in the corner ( corner stepping stone where the gas line is roughed out) and am stumped on dimensions. The stepping stones are all 42"x42" and am trying to decide between a 30" diameter bowl vs. a 36" and a particular color thinking - linen or fawn or something like that. I think the 36 might be too large for this area. Help!
