5' x 8' guest bathroom on demand heat

5 years ago

we will have a 40 sf guest bathroom that won't have a direct heat source. what would be the best way to heat it from an on demand standpoint ? A heat source that is the most responsive when someone enters the room. The bathroom is in the home's overall conditioned space so it wont get significantly cold - perhaps it might get 10 degrees cooler than the rest of the house at most. Maybe a heat lamp, or floor heating under the tile, or something else? We have not started the renovation.

Thanks to everyone for your recommendations. I think i'll go with the wall fan/heater unit and keep the existing heat lamp - maybe swap it out for the dual bulb/exhaust fan combo. I also like the idea of the toilet seat warmer which would provide that extra level of comfort. I can wire the fan and heat lamp to a motion sensor & thermostat. Luckily the hot water heater is directly below the floor so hot water is pretty quick.

Nancy - yes, that is a good idea to have the fan on when it's really cold out and/or when guests are over.

again, thank you everyone

Floor heat is very nice (but not fast, although it could be on a timer); or a wall mounted towel rack (Runtal is one brand) can really crank the heat it does take 10-15 minutes to heat up (can also be set on timer). Also warms/dries towels.

A ceiling fan with heater would work. You could put it on auto on and off. Some of my bathroom lights work that way and the dehumidifier of the fan is automatic based on ambient humidity.

A heated toilet seat can be a nice touch as well.

What is the bathroom mostly used for?

We used in-floor electric heat because its in the basement and the floor is concrete/tile on grade. The electric grid keeps the floor very comfortable for walking on, and for getting in and out of the shower. We used heat grid from a company called Warmly Yours. In addition we have a Panasonic heat/vent unit in the ceiling and it works really well to bring the temp up quickly in the room. The Panasonic units are much better than the Broan and Nutone units you find stocked at the big box stores.

An electric wall heater, with or without a fan. Inexpensive and effective. You don't need many BTUs so a small one that will run on a (dedicated) 120v circuit should be plenty

I agree with Elmer J Fudd because the heat will be down where you want it. Just remember that some of us are fat and our bare legs get a lot closer to side walls than slim folks do. So don't put it too close to the "throne." I think that with a ceiling heater fan you won't feel it warm the room much if you are in there for a short time. They still do make the light bulb heaters that shine red light on you, and those can work if positioned right, but need a minute to warm up, too. ( and red is warmer than the clear bulbs you can also get for them). On bitter cold days with most family home, I would leave it on in a low setting, too.

I should have mentioned:

If you want it to be easy to use, get one with an off-timer or put it on a circuit with a wall switch having a built-in variable setting off-timer function. These are standard electrical parts and easy to find at the usual sources.
