looking for thumbs-up for this slab/subfloor/floor option

I have spent many late night reading this forum about what to do with my laundry room floor (relatively good condition, on-grade concrete slab about 7 x 19 feet)and have come to the following decision (from bottom to top):
1 layer of landscaping fabric (to keep the delta from possibly "clicking")
1 layer of Delta-FL
2 layers of 3/8 cdx, laid perpendicular to each other stapled together to form a floating subfloor (need to build some height to match connecting floor so not worried about height too much)
1 layer of some type allure/armstrong vinyl panel stuff

Does anyone see anything glaringly wrong with this setup or have a better suggestion? I have been fretting about this for a while and am looking for the "go ahead" from an expert or two.

Thanks all contributors, this is a great site.

It would make more sense to put the vinyl directly on the concrete or use ceramic tile. Plywood on concrete is always a bad idea, even tho DIYers do it all the time, real pros don't.

Not a pro but I wouldn't put plywood down unless it was on top of a moisture barrier.

Thanks for the input.

Wouldn't the Delta-FL count as a moister/vapor barrier?

(When I was ripping the old floor out (which I probably should have just left in), it was 3/4 plywood glued directly to the concrete with a few screws in here and there. And for the number of years it had been down, it was in pretty good shape, no rotting, mold, and was very dry, so I don't think moisture is too much of a concern)

Jadester, How high is your adjoining flooring? A 3/4" height variance is normal and can be easily be compensated for with a transition molding. I agree with Sam, plywood on concrete is generally a bad idea. Aside from that though, your plan sounds like it will both double the cost and double the work of this project.

I have about a 1 3/8 inch difference between slab and adjoining room.

I know lots of contributors do not like plywood and concrete, but I couldn't really find any alternative suggestions (except using something like the delta-fl as a moisture barrier.

If you were going to put down some type of vinyl panel flooring (thought about ceramic but it is a rental and there is less maintenance with the vinyl), what you would you suggest?

This is a rental? All of our units came with vinyl flooring and we are putting in ceramic as the vinyl gets damaged because it's costing us less than putting in new vinyl.

Interesting,

I would think that the tile would be harder to maintain, especially with the grout, than it would be to mop and clean a vinyl floor. This room also lead to the back yard so I am assuming that a lot of mud/dirt would be tracked in.

We don't do the maintenance, that's for the tenants.

We pay to have it installed (which we do ourselves) and any repairs (again, ourselves) and find both are cheaper with ceramic. Keep in mind, we're not as concerned about the look of the tiles as we would be if this was our home so we buy the tile on clearance - the last batch was a pallet and a half at 50 per square foot.
