Can you put wood flooring over ceramic tiles?

Answer 1

No. Generally wood flooring needs to be nailed down. You may be able to get away with installing a floating laminate floor over the tile, but I would check with the maker of the laminate floor for it's installation recommendations. Obviously a flat surface would be ideal.

Yes but not directly. You will have to include a self leveling underlayment. Engineered wood can be installed over a self leveling underlayment with adhesive.

Answer 2

Yes, and it's important that the tile floor beneath is level and the tile is secure and in good condition. You may want to put some sound control material under the flooring so that echoing is reduced.

if you glue the flooring to the tiles fill in any low spots with leveling compound. If the wood floor is being glued to a slick tile surface, rough the tiles up a bit by sanding them to allow the adhesive to adhere better. If you plan glue your floor and do not want to grind the tile (to make it rough) you can use a special primer for tile or use floating method of installation. But anyway, make sure that you have perfect floor leveling. Also check how high will be your new floor after installation and compare it with other rooms close to this area. You should also consider the clearance under doors and possibly remove baseboards before installation.

Alternatively, you can also float the floor. Some hardwoods are clickable, and you can put an underlayment underneath, and then add the hardwood on top (clicking it together), similar to how you would install laminate flooring. If the hardwood is not clickable, then you could use a similar method and glue it at the joints.

Answer 3

Yes - however the floor must be sealed, absolutely flat so it should really be covered in self leveller and you MUST ensure there is no way of damp ingress or the flooring will pop and twist.
