Well said Kach. I've installed a few heat systems, all covered with tile. No callbacks on the system, only feedback was the expense of operation.

Need to be very careful of other trades not to damage. I did them after sheetrock and trim, just before tile, by putting in pull lines for the power and sensor wires.

I would check with your flooring manufacturer to see if it is even possible under a vinyl plank. You may want to tile that bathroom floor.
