The cost of this mural is significantly more than other murals and requires an instillation kit. We are trying to figure out what the kit is and why this mural needs this when others do not. Our tile guy wants to know if this Is recessed into the wall, in a niche so it looks like it sits on a shelf? We are interested in installing our mural in the next two to three weeks and will be ordering mural in the next day or so. Since this takes longer to ship we would like to know as soon as possible to make sure this would work for our application, and can place our order. Thanks for your help!!
