Contractor Question - can you floor over tile ?

[Deschodt]

We're looking at a property that we like for plenty of reasons, but the entire house is tiled diagonally with a tile we don't love - at least not on this scale, it's in every damn room and it's cold both physically and visually. Jackhammering it all off (or room by room) would be a massive project making moving in impossible.

Is it possible/acceptable/reasonable (assuming nice ceiling height) to put a new "real" wood floor over (some of) that ? The tile is in good shape, flat, not very textured...No floor vents or floor plugs. Can you put real wood over it ? I'm not sure how real wood floors are installed anyway, glued to what, concrete ?
I am sure I could put laminate over some of it, carpet elsewhere, rugs, and live with it - but it probably will be too loud with laminate over tile, even with a layment in between, and create transition strips everywhere....

Just wondering what the deal is... I see people generally use a jackhammer like scraper to take it all off, never knew why (assumed it was ceiling/furniture height concerns). I've seen real wood floors glued to an underlayment of plywood but how do they do it on concrete floors ? What's the benefit of taking all that tile off ? Thanks in advance !

Its possible but it depends. On how flat the tile is (some tile might curve up at the corners), on how well the tile is adhered to the subfloor. Go around and tap on tiles with the butt of a screw driver, you'll immediately hear a hollow sound of a tile is not adhered. If you find one loose tile then the whole floor is suspect and may cause noise in the future. If the subfloor is concrete then removal is much easier. Engineered (ply) hardwood is glued to a slab or can be floated (glued at the T&G with padding underneath. Cleated or stapled at the tongue or even glued to a wood subfloor if the planks are 7" or wider. I would never offer advice on going over tile without seeing it in person. My advice is to have a flooring mechanic look at it (not a flooring salesman)

We had what I thought was nice flat smooth tile, contractor got it all out before putting down LVP

I would think you’d need to put down an underlayment on the tile before the flooring. But that raises it up more. Then you need to think about base height, doors/door jambs, etc.

Short answer is no but if tiles are sound, a floating vinyl floor can go over it and many of them look just like wood now (at 3' away). Baz will install it for ya

It will mean undercutting the doors unless there's enough space already. You'll be replacing all the wall base no matter what you do.
