Travertine ok stone for shower floor?

Q. I keep reading mixed reviews on whether Travertine stone can be used on shower floors. I was thinking about it but after reading bad experiences, I have kind of drawn back to the idea. Can I use travertine on a shower floor? Guy at the hardware store told me to seal it before and after grouting. But I read here that I should not seal? Kind of confused. Thanks

 

A. There are many types of travertine and most will work for this application as long as it is properly installed, sealed and maintained.

 

Here is what Maurizio said in a previous post...

"Travertine is an excellent stone indeed for a shower enclosure. However, your "probing" is kinda just at skin level... :-)

A stone is just as good as the installer. If the installer will not install it right on a floor or a wall, it may not be a big deal, but inside a shower stall a poor installation will only spell: F-A-I-L-U-R-E, no matter how good the stone is. The importance of sealing travertine in a shower stall is very marginal. The technique of the installation is paramount."
