How do you plan it?

I'd love to use the white tile board, but I don't know how well the seams can be hidden.

Sheet rock is easy to hide seems, but even with the most glossy paint, it won't be very reflective. It would also get dinged up pretty quickly I think.

Plexi would have to be replaced due to wear frequently, plus it has illuminating seams and is super expensive at the sizes needed.
