I use a funnel and dump some RV antifreeze in each jet, run the pump and then refill each jet and hope for the best. Not sure if this gets the water out of the pump but no problems yet and we do have minimal heat to the bathroom.
That's funny, I just finish doing exactly that as a test run, but not real sure if that is going to be enough. Kinda looks like it should be though from what I can see with the flashlight since everything slops down for self draining.
There is a small baseboard electric heater in the bathroom. Maybe I'll just close the door and set it as low as it can go. For some odd reason I don't feel real good about that option (don't know exactly why, just seems like a bad idea.)
The other way is there is a fairly large hole for the drain to go through to the basement. Maybe the escaping heat (once I pull the insulation away) coming up from the basement into the underside of the tub surround (and your trick) will be enough.
That jetted tub is shoe horned in, which will make repairing it a hard job in the spring. There must be some water in those jetted tubs since I got some nasty stuff coming out with the RV antifreeze like SuperBee stated.
