I'm putting a darkroom in a room that has a 11x11ft hardwood floor and moulding. I need to cover it with something that's waterproof, non-permanent, and relatively affordable. I looked at linoleum yesterday that say it can be installed with a non-glue option. About $120 at lowes. I'm not sure how i'd hold it down on the edges. I could add a moulding strip i suppose.

What options for flooring am i missing?
