How much of the room gets heated?
Electric floor heating goes under the open floor only. It does not run under a vanity, under kitchen cabinets, under a toilet flange or under a tub, because trapping cable beneath a fixed object is both wasteful and a way to cook the element. That means the heated area of a real bathroom or kitchen commonly lands somewhere around sixty to eighty percent of the room’s footprint. A five by eight bathroom is forty square feet on paper, and after the vanity, the toilet and the tub surround it may be closer to twenty five. Quote the forty and the number is wrong by more than a third. This is the single most common budgeting mistake on a heated floor, and it is entirely avoidable: we draw the layout, subtract the fixtures, and price the mat off what is left.
