<< Are there hard tiles suitable for this application? Who makes them? What
colors available? What is used for adhesive (Thinset)? >>
It's all in your Yellow Pages under "Tile", "Flooring", other entries. Shut
down your computer, get out of your chair, put on your coat, grab a note pad,
get in your SUV and head down to any of the stores on your list. There will be
real live people there that know a lot about tile, techniques and materials.
Most of them will be several skill levels above the help at the box stores.
Since they supply local contractors they ought to be more knowledgeable about
what will work for your project. Go for it and enjoy. HTH
