I had in my head that laundry could continue to dry, even in sub-zero weather, but as it happens, when it is wet and around zero and there is no wind or sun, laundry tends to get cold and clammy, and no where approaching dry.
My next thought was to hang the laundry on the small porch that Grandpa had built for us behind the sauna. We still had our drying rack from last winter, and I pressed it into service. Alas, even with the snow not actually falling on our clothes, they didn't see to be drying in any semblance of an acceptable time period.
Bringing the rack from outside the sauna to the inside improved things quite a bit on the drying front. With a fire on in the steam room and the door propped open, it only took about a day or two for most things (save mats or heavy items) to dry out to a useable degree.
Finally, Donna pressed on me a suggestion that I had first put forth before the sauna had ever been constructed.
She had observed that the sauna seemed to take quite a time to warm up. Attributing that to the fact that heat rises, and we have a rather high ceiling we both concluded that much of our warm air was spending its time up in the peak of the sauna.
Heading up there with two lengths of one by four inch boards, about five feet long, I threaded clothes line back and forth through holes in the boards, and then screwed the boards into the rafters of the ceiling. I made sure to tension the clothes line so it didn't sag too much, and then came back down to the floor.
Pressing into service a large number of clothes hangers and the hook we use in the yurts to open and close the domes, I was able to easily hang the laundry on hangers, and then raise the hangers up into the rafters and in turn hang the hanger on the clothes line.
I have to say, this worked amazingly, amazingly well. The rising heat when the sauna is in use dries clothes extremely quickly. I have certainly hung heavy items up in the early afternoon, and been able to bring them down warm and dry later in the day when we actually take sauna. This is one idea that I am going to declare a real winner.
It isn't difficult to hang everything on hangers right from the spinner of our washing machine - and it actually should be even more helpful to just bring items in on the hanger and hang them in our (as yet to be built) wardrobes.
The only challenge is oversized bedsheets or mats. I've tried putting them across multiple hangers with some success. Socks seem to work most efficiently hanging five or six on a hanger with clothes pegs before transferring them up to the rafters.
We just have to be diligent about throwing hangers into the wash baskets with the dirty clothes, so they will be available in the sauna as items come out of the spinner.
