The floor is all real tile, 1/2 painted black. Walls are plywood, bead board, molding, and hand printed art paper for the wall paper. And no, not hand printed by me. I thought it would be so easy to grab some scrapbooking paper, but nothing was big enough to use, or would work to put end to end and tile the walls. Paper I ended up with was way more than I planned to spend, but seemed like the only good option I could find. It's all done with a metallic ink and looks gorgeous, so I feel like it was worth it in the end.
The whole thing is 36" x 24", and about 24" tall.
