At this point you are not comparing apples to apples. If these units were
fundamentally the same, they would cost the same to run. It sounds like the
one unit has a larger heater, which if nothing else would produce more
steam, faster

I'm planning to purchase a steam shower for my master bathoom and have
been doing some serious research, but I'm still hesitating between a
110V unit and 220V unit. The 110V is certainly more convenient, but
it's not ETL or UL certified. THe 220V is ETL certified but I heard
that it's very costly to run. What shall i do?
