Does a concrete slab floor need to be level prior to tile installation?


I'm doing my kitchen remodel. I subbed out the tile work. I am in the process of removing the old linoleum. The tile guys are set to come out for a total of two days. I've only spoken to the flooring salesman. They specialize in floors only. He stated that the linoleum floors are usually level prior to installation, so he doesn't see a problem. He said he built in a little bit into the labor costs to cover any issues with the floor level. I'm not sure if the tile guys will even have time to try to level it. Will the thinset help level the floor? I've used self leveler in other areas of my house (this was for DIY wood flooring). I've read that the floor should be flat, but I need them level as well. It will help with the cabinet install. I want the cabinets to be level as possible due to the granite countertops.

I think the tile guys will get the floor flat. You can level the cabinets with shims.

This is so typical. Contractor doesn't want to be bothered coming to look at the job. Salesman says yada, yada, yada and there is no contract and possibly not a written proposal. Then the estimated 2 days becomes +++ and more $$$ are needed and, and on and on it goes with the end result being a disappointed home owner.

Linoleum and tile does not need a level floor, it just needs to be flat and not flexing.
How does this guy even know what size, length of spans, spacing your floor joist are or what's there for a subfloor.
All that needed to be known before even thinking about installing tile.
Flexing floor = cracked tiles and grout.

This bears repeating because it is important and something tells me you aren't getting anything near a professional installation from these guys.

It is a concrete slab floor. There are some minor low spots. Should I use self leveler? I guess I'm mixing up level with the floor being flat

Don't use too much water when you mix it up. It may crack.

I kind of regret DIY the floor removal. They were going to charge me 120 for the removal of linoleum and another 60 for floor prep. It was a pain to get all the adhesive up. I don't see how a two man crew could remove the old flooring, prep the floor, and install the tile in one day. The second day was scheduled for grout.

Joists? What joists? We need to read mo better, and not worry about getting more posts answered.

I'm wondering how big an area this is since they only wanted to charge under $200 to remove and prep the floor. I wonder what's on the floor now that you removed the old sheet vinyl. Any pics?

Two days for the entire job? I too wonder how much time they'll spend prepping the slab.
