It depends…

[Sauerkraut57]

The first question is how high is going to be installed? If it is only a foot or two then there should not be a problem. The second question is what is it going to be installed to? Cinder block, brick, or wood? If you are planning on do it to wood, then don’t do it. This will lead to a bad moisture problem behind it. The third question is, do you have any idea how much work you are talking about? Stones are a lot harder to cut than tile. First of all they are round and can be slippery. When you go to cut them, they are going to want to turn. If it were me, I would you cultured stones that are made for this purpose.
