In the past we have used a little electric space heater for the bathrooms in the winter while showering since we keep the house temp lower but don't want to get chilled after taking a shower and it helps but is always still chilly feeling, I guess from the humility the shower creates for some reason since it still feels cold. Or maybe just the difference in temps from the hot water to the room so it feels cold even though it isn't. I even thought about using a small Mr Heater while in the shower. Does anyone have suggestions on a type of heater that would work well in a bathroom like this?
There are electric heaters that mount under cabinets that I have thought about putting in my bathrooms. Thermostatically operated, they could take the chill off. Here is one... Cadet Perfectoe 1,000-Watt 120-Volt Fan-Forced Under-Cabinet Electric Heater Black-UC101B at The Home Depot
Baseboard heater start low and allow the heat to rise, so the heating is petty even. 220-240vt is more efficient than 110vt, and can be controlled by a thermostat. I have a similar one to install in my bathroom at the hunting cabin (to keep the pipes from freezing) Shop Fahrenheat 72-in 240-Volts 1500-Watt Standard Electric Baseboard Heater at Lowe's
Then try either gas or electric infrared heaters (wall mounted below ceiling). If you go gas, get the one that does an orange glow, not blue. Blue heats the air, orange heats the objects in it's range, as well as the air. (It will heat you). This is an outdoor unit, but it will show you what I mean.

The humidity from the steam should actually make you feel warmer because the moisture on your skin will not evaporate as quickly and cool you down. This is why 70º still feels chilly in the winter (when humidity is low) but is quite comfortable in the summer (when there is a lot of water in the air). Anyway, you should not need more than a few hundred watts to keep an average sized bathroom respectably warm. I have a 1500 watt heater in my large bedroom with a vaulted ceiling, and even the low 750 watt setting is way more than I need. I suggest that if it is too cold with what you already have, either your expectations of comfort are unusually high or your house is seriously under insulated. Also keep in mind that if you are running the vent fan, that is the same as opening a window. You're probably sucking the warm air out of the room faster than the heater can keep up. Simply not using the fan will go a long way in keeping the place warm.
You can mount an infra-red heat lamp in the ceiling. Not a lot of juice required; couple amps. But the infra-red is nice and warm as the heat hits you directly and isn't working so much to heat the room. It might be all you need to feel more comfy when exiting the shower. Pretty common feature in hotel rooms. AT
I've used a portable electric radiator heater, similar to this one: Shop Oil Filled Tower Electric Space Heater with Thermostat at Lowes.com It may not be feasible, depending upon size of the bathroom, but it works admirably to keep the temperature in the bathroom a few degrees warmer than the rest of the house. Just set it, and forget it.

Check out Northern Tools. we bought one for the shop office that works well and does not take up much space in the wall.
You can get these on sale at the end of season. I got two-for-one at Lowes a few years ago. With that said, I tried to heat a sunroom last winter with one of these when the temp got below freezing here in GA. I left the top of the screen door open for venting, and even with that, you could barely breath in the room after about 20 min. I don't recommend this product inside of a bathroom. One thing I haven't seen mentioned yet is a ceiling vent that has a heaters.
