At my fiancee's insistence we are installing heated floors in the master bath, but I don't know if I should be ordering enough to install them under the shower as well. Is that legal or safe? The electrician is doing the connections, we may do the tiling or may hire it out.
Also, is buying heating systems as a mat worth the $100+ premium vs. buying a large roll of wire with some tie downs? We re doing 100-105 sqft if no shower, 110-120 with shower.
The math is a little fuzzy because 1) we haven't nailed down the size of the shower and 2) three walls have Mansard ceilings so you can't actually stand next to the edge of the wall, so I figure why heat where you can't stand and I will stop the heat 16" before the wall. I'm also not sure if I should heat where we would like some custom cabinets built (to fit with the sloping ceiling) but I suspect it will be a long time before we can get such cabinets. I'm also not heating under the vanity.
