Yes, you would have more trouble than it's worth, since stacked stone does not have grout. The water would get behind the stone and eventually cause mold issues. You are better off to have one of the dry walls in your bathroom done with the stacked stone if you still like that look, but not the shower.

And, if you slip and fall against it, you may need a skin graft! Ouch!

Oooh! A science project! All of the dead skin cells and soap residue feeding the mold culture will definately take home a gold medal in the competition.

Germ factory!

do not even consider this! even heavily textured tile that is grouted creates a serious cleaning burden.

It's best to use that product around your tub surround and not in the shower. Your tile rep is correct as is everyone above.

And when some good-intentioned person tells you "but this gets used on the outside of buildings and gets wet all the time so it won't be a problem", remember that splashes of shampoo conditioner soap body wash etc... are rare outside of a shower ;).

wow, thanks! moving along to plan B rapidly... :)

It would be beautiful to put on a wall that doesn't have water on it. You need to waterproof board behind tile for shower. Or you will have big problems dn the road. With Mildred.

Bigger issue is those are made to mimic dry stacked stone so there is no grout between the stones which means the water will constantly be getting behind and in between the stones. Fine for exterior applications but questionable for interior use.

That said I guess with a properly sealed substrate and then regular sealed stones it can be done but that would lead to the big question; WHY??

I am curious with al the tiles available why this is the one? Also can you post pics of the rest of the design. I am not bashing just curious as to what the design is. Heck, I am always open to new designs and sometimes the oddest components work well together.

I recently moved into a house where this was done in one of the showers - two sides are the stacked stone, one side is glass, and the other side is completely open. The shower is AWESOME! and there have been no issues. The shower room is quite large and there is good ventilation...it might not work as well in a tiny shower. The shower was done 8 yrs ago and still looks like new. I will try to post some pictures.

What leaves this topic open is the complete lack of horror stories involving ledgestone in showers. The mildew, the mold, the the off/bad smells, surface or sealant or adhesive degradation due to constant moisture contact. Lots of tile and contract pros saying 'Don't & Never' but no clarifications from either pros or DIYers with exactly why not and what happened. & then a solo homeowner stating ZERO issues from a purchased/pre-installed situation. Interesting

So catt266... What was the decision on this year-old idea?
