This is not something to be though of when you run out. Soap needs to be cured for 4-6 weeks before using. The process of leaching lye from ashes is a little difficult and can't be done while you are waiting for a bath. (Well it could but until the lye leached and the soap cured, I am not sure you would have a lot of friends left;-))
We always keep at least a 6 month supply of soap on hand, and supplies to make at least 3 batches.
I have found that super-fatting (adding at trace) with mineral oil works very well for a fraction of the cost of most oils that are commmonly used.
