Ok, I thought that would get everyone's attention.

I'm in the process of drawing up a fantasy castle, but it's fairly realistic fantasy. Roughly how many guarderobes/latrines does a castle need per occupant? Or should that be how many occupants per latrine?

What washing/bathing facilities (if any) should I include?

Should laundry be done in the kitchen? If not, where?

As you can see my historical knowledge is a little lacking, so I'd be grateful for any help on the practicalities of castle life.

Thanks.
