This job was for an already existing bathroom so we had to put the tubing under the floor. The ceiling below is actually an enclosed porch room, so the homeowner pulled the ceiling down and we installed the plates and tubing. The room was at one time heated by steam radiators but someone removed them. There is currently electric baseboard heat which doesn't work well. The radiant floor doesn't provide all the needed heat but there is also a very large hydronic towel warmer going in and between the two there will be sufficiant heat output.
