I have boarded at many different barns with indoor wash racks. Most have a plastic sort of sheet (a little bit textured and colored white) that I am not sure what it is called. It is usually installed over wood.
Some have tin, IMHO exposed tin is a huge no-no for horses. All it takes is one swift kick and a hoof or leg gets caught.
While wood is not the easiest to clean it is commonly used.
Rubber mats are also sometimes used.
I think the most important things to look for are:
-easy to clean
-sealed (sometimes people pour a concrete curb around it)
After that there are many different levels of cost and appearance. Soooo many options.
