Properly just shower Muggles.
They want to swap from bath to super sexy shower, usual plumbing headache.
Plus condensate from boiler room, all low down.
Yep, two pumps, unless a suitably large sump can be arranged for both. Condensate will be a tiny amount, easily able to be dealt with by (a type of pump whose name I have forgotten?), it uses flexible pipe, around a rotating shaft with rollers, commonly used for HVAC. A shower needs a much higher capacity pump to deal with the flow.
