No personal experience with limestone but from reading about stone it is usually considered inappropriate for the bathroom. If you really like natural stone I'd suggest trying to find a travertine or marble instead. They are still vulnerable to surface damage -- etching -- from acidic contact, but sealing will keep them relatively safe from absorbing other liquids.

I think the best resource for doing your own reading my be www.findstone.com

I hear that there are some limestones that are much better able to resist damage than others -- the dark ones, particularly. If limestone really makes your heart go pitty-pat, I'd go to a very reputable stone yard or tile store (Walker Zanger comes to mind) and let them guide you to which stones are better-suited to your purposes.

I learned at Hard Knocks U. that some are pretty easily damaged...

Also, there are some travertines that have a very 'limestoney' look to them. Those might wear a bit better. And there are, of course, the limestone-look procelain tiles that wear like iron.

I would tend to agree with that, although right now I'm working on a hotel where every one of the bathrooms is done completely in Jerusalem Stone... floor, tub deck and splash, and shower:

Oh Bill, I'm fainting here...that is *so* beautiful. Is that that hotel you were hoping to get? I love the accent smaller rectangles. How are you finding it wrt stains as you're working with it? Does it clean up easily from grouting?

Limestone, marble and travertine are basically the same stone at different levels of density. Usually the most dense being marble followed by travertine, then limestone. I would not even think of using hair coloring products on a natural stone floor. If that is the use the bathroom is going to get I would put in porcelain.

Those little 1x6's-- they mounted them wrong-- 11 to a 12" stretch, so we have to unmount them and install them one at a time. I have nightmares about those pieces!! Something akin to the brooms marching in Walt Disney's Fantasia!!

As for clean up, get this-- it's polished limestone with Spectralock grout. And now it's time to be proud pappa for a minute-- Adam's the only one out of FIVE tile crews who's not leaving any epoxy residue behind! :-) It has alot to do with the cleaning packets they give you with each unit.

I received a sample of the Jurastone Blue-Gray limestone and I put some mixed hair coloring solution on it. Left it there for an hour, and wiped it off and there was no staining at all! Didn't even have to scrub it. This was even with no sealer. I was shocked. Then I poured some eau de tiolette on it and left it there for 15 minutes, and I couldn't really see any etching. Since these were the two things I was mainly concerned about, I think it might be OK. Also going to try some bleach and nail polish remover. So far I'm impressed with this unsealed stone. I know it's not sealed as it got quite a bit darker after I wet it and absorbed the water. I also like the enhanced color as it's a little golder.

Maybe this isn't as delicate as it seems ;-).
