I did say if you have access, a loft with a loft ladder or other means,
would be more suitable than a switch located on a 9 ft ceiling, where by you
have to use a ladder/chair in order to use it.

Try one of these:-

providing you have access.

You can go for a switch outside the bathroom if you prefer.
