Anna, I don't really think ANY of them are that bad, including real stone. I had a marble called pink argenta on my master bath floor when I had my house in Connecticut, and I wouldn't want to try running on it, but to walk across it, I never had any problems, nor did anyone else who used that bathroom. I don't think the Laufen is any more or less slippery than any other rectified polished porcelain. I just think that like myself, they don't see it as much of a problem as other companies might. Crossville's language might also be a legal disclaimer, much like McDonalds warning on the side of their coffee cups that contents are hot-- because some moron with no living brain cells won a law suit claiming they didn't realise...

My friend Nancy had the same problem in her bathroom. She used a company called Johnny Grip, she said it worked really well. I think the site is www.slipperytile.com you can try it out, it worked for her. Here is a link that might be useful: slippery tile

Hi Marita40! I live in Atlanta, GA and while we don't get anywhere near the snow and ice that y'all get, we had a serious winter storm last week. Once I got the buildup out of the garage, I ended throwing down some gravel (needed more traction than sand and the salt would mess up the finish on the floor). Plus it helped when everything refroze overnight. Stay warm!

Polished travertine wouldn't be suitable for most people for a kitchen floor regardless of whether or not it was slippery. It's relatively soft and porous nature which leads to scratching, staining and etching would show every bit of patina on a polished surface. It'd be OK for honed, if you were OK with a more "lived in" look, but polished would be a nightmare for most to actually live with as flooring. Add in the slipperyness factor that you are worried about, and you really need to move on to a different choice for your floor. Perhaps a honed version would work for you if you are OK with the maintainence needs.
