Space, power and setup
Delta rates this size for a maximum shower volume of 75 cu ft, so measure your enclosure against that rating. It needs a 240 V single-phase supply with a 25 A breaker; have a licensed electrician confirm the circuit and a licensed plumber handle water and steam connections, following local codes and Delta's installation sheet. Our earlier listing described this model with a digital controller and square steam head, while Delta lists EP103323 as the stand-alone 4 kW generator. Please call us to confirm exactly what ships with your order, and see the SimpleSteam Square Control Package if you need a control and steam head.
