I am having a full basement bathroom installed and just wanted to ask a few questions regarding flooring choices.
Half of the basement is already finished. So, we will be breaking through the wall that separates the finished from the unfinished side and adding a bathroom there.

The current finished area is on 2x4 sleepers with 3/4 plywood and covered in carpet.
So the bathroom is framed out with 2x4 sleepers glued and red Tapcon screwed into the cement, with 3/4 tongue and groove underlayment sub-floor.

We were all set to do tile, but I found through a little bit of research that tile over concrete sleepers is a recipe for disaster. Moisture/dampness equals movement of 2x4s and therefore cracked grout/tile.

So, if we decide not to rip up the current floor and do a mudjob, then tile, what are our other options?

Can we do a engineered hardwood on top of 2x4 sleepers on concrete? Or laminate?
I'd rather not do vinyl or linoleum...

If yes, is there anything we have to do special for this type of installation?

Any advice is greatly appreciated!
