So you'd still have water running around all over the place.

Yes, but if any of it leaked, it wouldn't be necessary to rip up the floor to fix it (nor to fit it as a replacement in the first place).
(There is a heat recovery ventilation system which I could possibly add heating to (air source heat pump? (which, if reversible, could be air conditioning too)) to create a warm air system, avoiding hot water altogether. But keeping hot water would be easier.)
