Can I lay 18" x 18" Travertine tile?

I am going to install some Travertine tile in my half bath and was wondering if is can do this on top of the existing vinyl flooring without adding subfloor?

Pull up the old vinyl.

What type of flooring do you have? Concrete slab, or plywood?

If it's plywood subfloor, you need to have about 1 1/8" of subfloor in order for the floor to be sturdy enough for tile.

Use a 1/2 x 1/2 x 1/2" trowel

Make sure you have a good subfloor before doing this. If it's to thin, your tile and grout will crack on no time.

Your getting ahead of yourself here. For all natural stone installations your floor has to be twice as strong as it does for ceramic tile. Whats size floor joists do you have, what is there on center spacing and what is there unsupported span from below? At a very minimum you'll need at least two layers of plywood totalling 1 1/4" in thickness and either an isolation membrane or cement board over that. This all assumes that you meet the deflection for natural stone of L720. Answer the questions and we can help you determine this.
