18 sqft bathroom

Added: 11/12/2013
9.1ft long heating mat was suggested as the best mat size for this project. After installing 30" long heating mat slightly move to the left (just few inches) and runs along the tub. Last row is 11" wide by the sink, the rest of heating mat will be used as heating cable and will cover the area where mat doesn't fit.
Offered 20" wide x 9.1ft long heating mat kit is: HTMATKIT-120-15
