You would have to check if its suitable for bathroom use.

That is the exact fan heater that has just self-distructed after many
years of service - but it's also the same fan heater that only heats the
top two feet of the 7ft 6in high room :-@

If that is the exact fan then the fitting instructions suggest it can be
preset on installation for 1kW OR 2kW = it doesn't necessarily switch
from one setting to the other. The thermostat has 5 settings the higher
of which is 32 degrees C. On a down blowing fan heater 32C is bloody
hot, even at the ceiling height of the room. With a 7ft 6inch high
ceiling at 32c I would expect the temperature lower down to be in the
mid to high 20s C.

I wonder if either the thermostat was set too low on installation (the
lowest setting 7C, the highest 32C) or the safety cut out has been
kicking in on a regular basis. The safety cut-out prevents internal
overheating. Overheating may have been caused by a build up of dust semi
blocking the air flow. Luxury and soft toilet paper is a great source of
lots of fine airborne dust!

[quote from installation/operating instructions]
Ensure that dust or fluff does not accumulate inside the
heater as this could lead to overheating of the element. Use a
vacuum cleaner to remove any fluff which does accumulate.
