I'd get down to sub floor. If you can get a shovel under the luan it will just come up in big chunks
Ceramic tile in bathroom with vinyl flooring
Hi guys, I'm a carpenter by trade trying to update my house and wanting to install some 18 x 18 tile in my second floor bathroom , I did it in my basement over concrete floor and came out great but just wanted to see what are my options for the second floor the house is 13 years old the floor beams are TGI's 16" oc with 3/4" tongue and groove ply as underlayment now the bathroom floor has 1/4" luan standard builder sheet vinyl over it and then I installed vinyl tiles on top (bad economy) of it but its time to improve I'm planning to install 18" x 18" tiles, the total area is 16' x 8' with some angles , should I remove everything to bare plywood or can I install a backer board /cement board with thinset and the right nails /screws over it and the tile on top? please advice.
Thanks,
Thanks,

Thanks! what do you think about Ditra over the ply? or the cement/backer board is better?
Take an old blade on one of your skill saws set it to the depth of the vinyl and underlayment, Slice it into 1sf squares and pry it up, should be easy unless it is glued down, if it is slice it into 6" squares. if you have a diamond cup wheel grind off the staples otherwise pound down or pull em out. 1/4 backer board, 1/4 notch thinset, and nail with a roofing nailer. Schluter is a fine product but Durock is more than sufficient. With 18" tile I would use Mapei LFT or Ultraflex 2 with 1/2 notch and back butter.
Ditra over plywood, need a minimum of 3/8 plywood over T&G planks of planks are 3/4 thick. I'd go with 1/2 inch then ditra.. but you should use strata mat considering this is only your second tile job. Ditra requires two different thin set .. modified bottom and unmodified top.. strata mat is by LATICRETE.. go with that
Thanks a lot guys, I will follow your advice ,I just want to do it once.
