That sounds pretty great, actually. Pour a slab, put down sleepers with foam board in between, plywood and cement board on top, run hydronic pex all across it, and then pour another couple inches of concrete... I would really like that floor. Easy to clean, fireproof, toasty warm all year.![]()

Low maintenance was the thought, 10mm vapor barrier with 2in foam with 5- 300ft loops of pex staples to the foam with rebar on top of that and then 5in of 5000psi concrete hooked to a Bosch 151k btu combi boiler
