No. Heating elements should only be installed in usable floor areas. Avoid placing them under permanent fixtures like bathtubs, toilets, and vanities. Why Not Under Fixtures: Bathtubs: Heating under a tub wastes energy (the tub insulates the heat) Creates unnecessary heat that doesn't benefit the bathroom Difficult to access if repairs are needed Risk of damage during tub installation or maintenance Toilets: No benefit to heating under a toilet Wastes energy Complicates installation and future repairs Vanities & Cabinets: Heat is trapped and wasted Can damage cabinet materials over time Reduces system efficiency Where to Install Heating Elements: Focus on: Open floor areas where people walk barefoot In front of the vanity (where you stand to brush teeth, wash hands) Around the toilet base (for comfort and safety) Entrance areas (for that luxurious warm floor feeling) Any open floor space Measure Your Usable Floor Area: Step 1: Measure total bathroom dimensions Length and width of the room Step 2: Identify and exclude permanent fixtures Bathtub footprint Toilet base Vanity footprint Built-in cabinets or shelving Step 3: Calculate usable floor area Total square footage minus fixture areas = Heated area Example: Total bathroom: 50 sq.ft. Bathtub: 10 sq.ft. Toilet: 2 sq.ft. Vanity: 8 sq.ft. Usable heated area: 30 sq.ft.

Do you want me to go straight here or maybe just to here? I think the vanity is going to be here. Yeah, making sure that we get our toes warm is important. Okay, I think what we'll do is pull some of this cable from under the vanity and use it so we get coverage coming into the bathroom and our feet are not cold there.

So let's reconfigure it.

Perfect.
