Hi guys I am finishing the bonus room above my shop and have put in a bathroom with a toilet and a sink. I am looking into the best way to heat the water. There will not be much use during the week. The kids (little) will use it as a playroom and we will use it as a games room and to watch movies. I may eventualy put a sink below in the shop but still the hot water requirments are next to zero. I am wondering if a realy small tank or a small instant heater is the way to go. I could turn the tank on if we are having a party, and then I wouldn’t be heating water all the time. If anyone out there has any other options for such a small useage I would apreciate it. Thanks Angus

Yeah, a 10-gallon electric tank heater should do the job.
I don't think that you will
I don't think that you will need much capacity. There are 4 and 6 gallon heaters that should do what you need.
Thanks for the replies guys. I suppose the instant water heater would be a waste as a 4 or 6 g tank would be almost instant anyway. Thanks Angus
Instant is rated by flow, not reserve capacity, meaning you'd need a pretty much full-sized instant unit (though on the small side), with similarly high gas/electric demands. Would be much more expensive and wouldn't save much (if any) space over a small tank. Probably more expensive to operate too, if you went electric.
We have a couple of 120v instant WH in use at couple of our facilities. They work well for a single fixture. The only caveat is water hardness. They don't like hard water.
We also have a couple of places we use the 5-6 gallon storage typ HW tanks. Not much differance in the cost of either type. About $140 t0 $180 for either.
I'd go for one of these, or
I'd go for one of these, or similar.

A small 3-5 gallon unit should fit under the sink. A reasonable choice and minimal energy use. Could do a small tankless under the sink, I suppose, but may be expensive and require e.g. a large electrical servic (and wire and breaker), which may not be desireable. But check to make sure; may get a small one w/ 20 amp service requirements.
Thanks guys I am going to check on those here tomarrow.

As cost effective as a 5 gallon tank under the sink and less obtrusive. We have had one in service for 8 years now, with no problems. 120v, so know additional pulls from the panel.
But note that the 1/2 gpm flow rate is "optimistic".
How is the flow rate on it? You don't notice a diference in that sink do you?(as compared to a normal sink)
thanks for the link.
