The marmoleum is installed in my trailer and it looks great. It wasn't cheap having it professionally done, they worked all day and back for a few hours the next morning, but so glad we didnt have to contemplate doing it. I saved a bit off my "budget" (I have a budget? I think that ran away a few months ago) by not going with my original "gotta have" stainless steel countertops. I used the same marmoleum on my counters and it looks great. Just now in the process of acquiring the retro style metal trim around the edges.
I went with Marmoleum Graphic sgraffito. black with off white flecks for appropriate 50's retro look.
My shelves are also lined with it.
Appreciated all of the input.
