I still have tubs like that, Pippi, using them quite often, EXCEPT for bathing in! I don't think I'd fit in one anymore!
Great idea on the outdoor shower. I sure need one outside my shoffice, sure would be handy.
And yep, our old pump in the well house used to need priming. Nowadays we have submersible pumps that are down in the wells, in the water, that stay primed. New age, eh?
Memories sure are a good thing, aren't they!
Best to you and yours!
