Have a look at The label on the back of the shower waste pump in the illustration it appears you can have double insulated functional isolation transformers without a PE conductor.

But they must be 30 mA RCD protected even if the transformer is mounted outside of the shower room, other manufacturers make similar shower waste pumps which are SELV, but the transformer is within the pump unit rather than a separate controller, do they still need RCD protection as the pump unit is generally within the shower room.
