Safe portable heater in bathroom
We have forced air central heat but there is no outlet in the bathroom. In fact since we live in CA and have a very well insulated condo, the heat rarely comes on we prefer a cool home. However the bathroom is uncomfortably cold for showers especially the tile floor! I have been thinking of putting a portable heater in there on the opposite side of the room from the shower- perhaps a baseboard type to get the floor warmer - but I am concerned about the safety of using one in a high moisture area, there could always be splashes. We do of course have GFCI outlets in the bath, is that enough protection or do I need to look for special safety features in a heater?
Alternative suggestions would also be welcome. We don't want to invest a lot in this Ie permanent baseboard or in-wall heat) because we really only need the heat for 1-2 months per year and there are lots of HOA restrictions on installations.
