Travertine tile over wood subfloor
I’m wanting to install travertine tile (Sandcastle, 1/2”x16”x16”, factory filled and semi-polished) in my small bathroom (7’x10’). The bathroom has been completely gutted, including new treated 2x10 treated floor joists (16” oc, 14’ span) with ¾” plywood flooring.
My plan – add additional 3/8” plywood with 30# builder felt between plywood (3/4”+3/8”=1 1/8” sub floor). I plan to then use a modified thinset (3/16” v-notched trial) under Ditra and then apply a white un-modified thinset (1/2” v-notched trial) under the buttered tile. I plan to use a non-sanded grout to fill the 1/16” spacing between the stones. I do not plan to seal the travertine. Should I seal the grout?
Am I on the right track? Overkill? Beef it up? Go with vinyl? Lol
What a great forum! Thanks, as I plan to do this 1 (one) time!
