Tiling concrete floor

[SMG]

My shower room floor is re enforced concrete, sat, I believe on polystyrene slabs, which are sat on a blue type plastic sheet, (Built 7 years ago). The concrete was covered with asphalt then tiled. My problem is that the floor is higher than the adjoining room floor, & I want it level. If I remove the tiles & asphalt, it will be at the level I need.

So, can I then re-tile onto the concrete floor?

Would there also be any problems with dampness or cold?

Thanks

Yes you can tile onto concrete but can you confirm this is not a floating floor?

Have you removed the asphalt? Do you know the condition of the floor? Is it flat? What type & size are the tiles you’re laying? Before starting, read the Tiling Forum sticky & archive posts & ask for advice, it may prevent you making disastrous & potentially expensive mistakes.
