Please be sure and click the link at the bottom of this post and see how my kitchen floor turned out! If the old vinyl is in good shape and glued down firmly with no seams popping up or holes, then you can put a new layer of vinyl flooring over a current layer. If the vinyl tile are well attached to the subfloor and not peeling up around the edges, you should be able to tile over it. Good luck with your project! I want to retile a bathroom with ceramic or porcelain tile and the house was built in the 60’s and I am sure that the vinyl that was originally put in contains asbestos. Of course with laminate, you won’t glue the flooring down, like you would with wood or engineered wood flooring.
I would be to take up the vinyl and one layer of plywood, then put down 1/2″ cement backer board and tile on top of the 3/4″ plywood subfloor. Depending on the specific type of flooring, you may be able to lay a laminate floor directly over vinyl flooring. If the vinyl is on a concrete slab, and there is moisture under the floor, you should put down a layer of 6 mil plastic first. With the old flooring removed you should now have plain view of the bare subfloor.
As is, it looks like the new floor may be roughly an inch higher than the old, requiring quite a transition to the hardwood floor dining room (& cutting a door shorter). The problem with NOT removing, and flooring under everything, is you may end up with the dishwasher boxed in. You may then need to lift the countertop if you one day replace the dishwasher. Then on top of round gravel, there are plywood boards, and finally Vinyl flooring on top of that.
I have a subfloor, underlayment (1/4 inch) and a single layer of securely glued vinyl flooring that I am hoping to leave in place. Now I want to lay ceramic tiles on top of that in our kitchen area, the floor is pretty firm and does not bend or squeak with normal load. I want to lay ceramic tiles over a concrete floor covered in lino but this needs levelling first. It is best to shop around several home renovation stores and even tile specialty stores and make sure you pick the right stone tiles for the look you desire. Good reputable stores will let you take home full size stone tiles so you can confirm the right look and feel to match your home dÃ©cor.
The carpet is held into place along the edges by long thing wood strips laced with sharp nail tips protruding upward. It would be great to just start laying tiles but the truth is the sub floor is more than likely an uneven surface. Even if the floor looks fairly even, you should take a level and confirm there are no uneven areas that are severe enough to cause issues with laying the tiles down flat. For carpet these floor imperfections are not an issue, but for floor tiles they can cause the tiles to crack and also take away from the final appearance. This way I would not have to worry about the mortar drying before I place my tiles.
