It is a tiny house with tiled bathroom and timber (possibly laminate) kitchen and living room. It will be a plywood subfloor and we are happy to do the installation ourselves. I have attached the plan of the area that we would be heating. Obviously not under kitchen cabinets, but does it go under the lounge (it won’t be a fixed lounge)? Email contact on the above address is easier than calling due to work schedules. Cheers, Tracey.
