As a child, neither of my grandparents' homes had an indoor bathroom! (Rural Cornwall).
One was a council house where the council converted one of the 3 upstairs bedrooms into a bathroom (ooh! the luxury!) so at night, one didn't have to remember which of the rickety wooden doors out on the patio lead to the loo and which to the coal-shed... but my other grandad lived in an isolated, old, old cottage that had 16th century origins. Thick thatch, cobbles on earth floors and the upstairs floor was cut from the same oak, its lines swooping and buckled along with the growth of the original tree! He had a hand pump to draw water from a well outside til I was 10! A persistent skin rash and a persistent GP who blamed contamination of the ground water forced the council, eventually, to lay on 'mains water' to the house, but he never had 'hot water on tap'! He had 'a scullery' which was half buried in the soil, beyond the 4' cobb walls. It was damp, dank and smelly, so as kids, when we stayed, we'd troop up to his sister's council house up on 'The Green' where she'd charge my mum 50p a bath! 
That grandad's house had an outhouse down a muddy, dark, country lane, the loo a deep pit filled with Jeyes Fluid, that night-soil men emptied every month! ; the seat a plank of wood with a hole cut in it, a good 20m from the house, (yes, past the coal shed!). As you can imagine, us primary schoolers weren't that keen on grabbing a torch and setting out into the wind and rain lashed pitch black, trees thrashing in the wind all around us, wind howling through the eaves to relieve ourselves in an unlit, spider strewn, chemical fume-house of an outdoor loo, alone at night. So we had porcelain chamber pots.... that smelled the room out by day break! It was such an 'other' experience for us kids I could never understand how, latterly, we'd spend just a day with that grandad then head off 50 miles to spend the rest of the week with the other one, with the bathroom, but, as a mum myself,. now... I get it.
