We've got a jack and jill bathroom at the moment which I really don't like. Can't see how to make it into a family bathroom without fairly extensive renovations involving the bathroom and a bedroom but it wouldn't be so hard to stick a divinding wall down the middle of the room. Only problem is that the current bathroom is 6ft x 9ft so the split rooms would be max 3ft wide each and that's not taking into account the width of the dividing wall. It wouldn't be so easy to split the other way due to existing door and window placement which I'd prefer not to change.
Looking online I see 3ft x 9ft is possible for a bathroom but practically would it be much too small? Anyone have a bathroom this size? The rooms are currently kids room and spare room. Eventually they'll be both kids rooms so I feel like a smaller space though not ideal isn't as bad as if it was a shared bathroom (either family or ensuite shared by a couple).
