The Mini Ceramic Fan Heater by Plus Minus Zero may be one of the very few portable heaters that has some design sense. This minimal heater bares nothing but the essentials, air in/out vents, on/off switch, and an electrical cord. The mini (more like micro) heater measures in at roughly 4” wide by 8” high, and is designed to heat small spaces that require a portable heater, rather than larger rooms. This heater would be perfect for a tiled bathroom in the dead of winter. Get em here.
