Paul,
I have a radiant heater in my bathroom mounted on the wall opposite the tub. It's one with a tubular element, about 1kW and adjustable rear reflector.
Sorry I missed that comment the first time around.
I must say that they were rather popular here as well.
To a certain extent, I reckon that they gave a better, more even sort of heat, not a blast of hot air as with the fan-type heaters.
Just a note Dave about bathroom ventilation fans, AS/NZS 3000 requires that they be supplied by an SELV (Safety Extra Low Voltage) supply, meaning 12 or 24V.
