This is the steam shower in the Master Bath. It is also set in a bed of mortar under neath for support. There will be doors that extend to the top of the unit to retain the steam inside the shower. The steam generator is in the basement and is plumbed to a steamhead on a side wall near the floor (it's hidden in this view). There is a time/temperature control in the shower to run the steam generator. And, there is a low-voltage light in the ceiling of the shower.
