Medieval Castles - Water, Wells

Photo: Medieval well at Brougham Castle (protected with a modern grid to guard against tourist accidents!)
Typically water for drinking or washing would be available on each floor. This water would be provided by a cistern at a higher level which would then supply the water through piping.
Bathing would be in a wooden tub which might well be covered with a canopy in cold times.
It was quite common for the bath and bed to accompany the Lord on his travels.
Brougham Castle in Cumbria still has its well visible within the castle grounds
