You most certainly can pour a new floor over your ceramic tile. If you were to use conventional concrete I would say you should pour a minimun of 3 inches both for strength and to ease leveling. Another and I think better way would be to use a self leveling concrete that can be aplied in a much thinner coat and if head room is a problem would be of help. It is a polymer modified concrete that flows to a level floor more readily. There are two types an underlayment one that would be fine if you are topping it with carpet, linoleum or laminate flooring. There also is a topping type that can be colored and even saw cut to look like tile or stone.

For regular concrete you will want either a mason or a concrete contractor and in my opinion the self leveling would be best done by one that either specializes in it or at least has experience with it. I have used it for small areas such as bathrooms and even though it sounds simple it cah be tricky to use and on a large floor special tools such as a guaging rake and a smoother are needed.

Why not just put carpet or a laminate floor over it for far less cost?

+1 to Don's feedback.


Can it be done...yes.


Is it done as an option usually...no.


If it is a basement floor, the overwhelming likelihood is that there is concrete as a base slab already.


What kind of floor do you want?


Going over top and thickening up the floor may create operational issues for the doors.

We don't like carpet so that out of the question. We really like concrete flooring and this seems like a good opportunity to get them. It's purely for aesthetics.


We prefer something light, polished but not too glossy.

The floor you just posted looks like a polished concrete floor or an epoxy floor. Both could be done with the self leveling concrete. You mayhave to cut the bottoms of your doors but that is not that big a deal. You just might have to get a carpenter to do it after the floor is done.

Looks more like polished concrete in that picture.


Why not pull up the tile, have the concrete below professionally leveled and ground (large concrete polisher) and then seal coat.


If you go that route, you don't need to add the leveling concrete or change the door heights.

All the prior comments look like good advice to me. My thoughts -

1) a thick (3-4" reinforced) overlay should work fine. I would be more leery of a thin overlay, because it is going to have basically no bond with the underlying tile (though it could be sprayed with an epoxy bonding agent to help some), so while it will not lift on its own or under foot traffic, uneven weighting by heavy furniture or installing a non-bearing divider wall could cause cracking. If you do put in new walls, I would be sure there is a foam pad (white closed cell spacing pad made for this purpose, usually used on temporary partitions over tile or laminate or hardwood where you don't want to damage the underlying flooring) underneath to prevent any point loading.

2) I would consider the effect of adding 3-4 inches of thickness - every inch counts in a normal basement whewre the headroom is commonly closer to 7 than 8 feet. I have seen several jobs where the homeowner or building owner regretted doing a concrete overlay because the even slightly lesser headroom made it look like a parking garage - a noticeably low, confining ceiling. Consider this not only from the aspect of what you like or find acceptable, but also if it will detract from resaleability.

3) Before considering an overlay, be sure you will not be impacting minimum code required headroom (usually already at a minimum in basements), or burying baseboard heating or electrical conduits, etc. Also, be sure your doorway headroom clearance will not be less than required by code - basement doorways are commonly already at code minimum.

4) since you are looking at polished or ground concrete anyway, the usual issue of having to pay a lot to fully remove the grout to provide a suitable surface for another overlay does not apply - the tile and grout can be rough removed, then the final bits of grout that are left can be ground down along with the top of the concrete to whatever finish you want. However, tile removal typically about $2-3/SF, concrete grinding/polishing about $5-10/SF depending on finish desired and if staining also, so your polished concrete look is going to cost you more than typical flooring (other than stone or exotic hardwood) at any rate.

If you go with an overlay, a specialty concrete floor contractor is what you want - I doubt you will find a residential one - this is predominately a commercial type of work. Check your yellow pages or google for local Concrete FLoor OVerlay companies, or for grinding/polishing Concrete Floor Finishing or Concrete Grinding and Polishing, then check those names on Angie's List by name for ratings and reviews, if any.
