Bathrooms are considered as 'Special Locations' as defined in BS7671 Wiring Regulations. Within the zones of the bathroom (which creates the requirements for IP rated light fixtures, fans etc) it is not permitted to install a socket outlet within 3 meters of a body of water (i.e. a bath) This is regardless of residual current protection or IP rating being present in the installation or at the outlet with the exception of an internally fused low-output transformer shaver point.
As most peoples bathrooms are not large enough to accommodate this distance it's unlikely.
The main reason for this is to prevent people using appliances in bath tubs like hairdryers or god forbit even toasters!!! (as flex length is not normally anywhere near as long as 3 meters, preventing misuse)
So the outdoor socket cannot be used with the bathroom, unless you have a rather large bathroom which would accommodate the 3 meter rule.
