Insulate Unheated Bathroom
I have a ranch out in the high desert. Typical winter temperatures are 50-60F during the day and 20-35F at night. Want to turn an 8x10 made out of concrete blocks into an occasional use bathroom. I don't want to heat it because it will be very occasional use (when I'm out there). Will any amount of insulation (styrofoam/fiberglass) do the job or will the temperature from the outside eventually get into the inside? If I hermetically seal the place with insulation, what temperature can I expect (given the day/night) range?

Ayuh,... Are you talkin' 'bout a bathroom with runnin' water, 'n pipes full of water all the time,..??
On a well,..??
Where's the well pump, 'n plumbing,..??
Is there electricity,..??

Yes, a bathroom with pipes full of water, in an area where night temperatures more often than not dip below freezing, sometimes well below freezing. Water comes from a local water district. There is electricity but the question is can I do without heating exclusively by insulating the heck out of the place?

Any electric in there? There is a simple device which plugs into a wall outlet and then you plug in a heat lamp or even a small heater into it. It can be purchased for under $10 and it is activated by low temperature. (we use them everywhere here in pump houses) If you insulate well enough you won't need much heat to keep it abouve freezing. Much cheper than repairing pipes and water damage.

OK, I suppose that no matter what I'm going to need a backup heat source. What do I google or search on ebay to find these $10 plug-in heat adjusting devices? Also, while we're on the subject, how important is this 40 degree limit? Heaters that claim to have anti-freeze settings turn on when the temperature reaches 44 degrees. What's up with that? I thought 32 was the freeze point and 20 was the supercool point which is when the real serious damage starts.

Just about nothing.

If it stays cold enough, for long enough, you will need to supply some heat.

If the insulation layer it correct and sufficient, many homes can absorb enough radiant heat from the sun during the day to slowly release it at night and maintain an above freezing temperature (barring supremely low overnight temps) in the space.
