Thanks for the compliments! This was one of our custom designs where we set a very deep soaking tub in a hand forged stainless steel and structural steel shroud then capped it with a 3" thick slab of chiseled edged granite. The complete tub is set in a well, fitted with drains covered by a bed of black river rock to act as a safety overflow. The shower head is recessed in the dropped ceiling along with infrared heaters. The shower is controlled by a digital electronic control.
This was indeed a complicated design and engineering process , all made possible by a great team of talented trades.
