Greetings;
We would like to put travertine tiles on our bathroom floor, and we
have the following questions:

- How strong is it? (It is, after all, full of holes....)
- Should we fill the holes? With what?
- How slippery is it?
- Are there different qualities (grades) of travertine? How to
judge?
- Would travertine be a good candidate for electric radiant heating?
- Any other particulars that we should be aware of?

TIA
