I haven't seen those heat lamps in places other than older hotels. If you are looking for something warm after a shower then consider a heated towel rack. Otherwise just open the furnaace vent a bit more.

I really like the effect of a heat lamp vs. a towel rack, underfloor heating or a heater fan. I'm going to look around and see if anyone is marketing things that are not circa-1980s in style and if I come up with anything I'll report back.
