Installing laminate and tile on slab. Is this a good idea?

Hi I just pulled up my old flooring, all that was there was a layer of laminate, a layer of underlay, a layer of vinyl tiles and then the concrete slab.

Saw this video on youtube.

Good idea or waste of money?

Is your slab below grade?

Why would you install a subfloor if you are tiling? You can tile directly onto a concrete slab provided it is stable and not moving a lot.

Hi my slab is not below grade.

Most of the floor will be laminate with a small section in tile, I was just assuming that if i did install a subfloor I would want the tile and laminate to be as close to level as possible.

On that note, how do you ensure that your tile and laminate will be level to each other?

Thanks for the response.

Laminate and tile will be approximately the same height once you install them. Choose a thick tile and you should be OK. Here is a picture of a 3/8" engineered floating floor up against 1/4" granite tiles on a slab that I installed for a customer. With Laminate, you would use a transition strip or "T" molding to make the adjustment from one floor to another.

I also did the tile work around the fireplace.

That video is wrong. First there is a very good chance that the OSB will not stay flat with that few fasteners. And every fastener ruins the vapor barrier. The tapcons put holes in it. I have been in flooring since 1973 and have never seen a system that puts wood over concrete work for very long. Does your slab have a vapor barrier under it? How old is the slab?
