The picture of the three items are two volume control valves and a thermostatic mixing valve, one valve controls the waterfall and the other valve controls the body sprays and overhead rain shower head.
Size of the steam shower is just under 5feet x 8 feet. With a height of a little over 7 feet. Around 280 cubic feet.
In the years before I built my shower, I was responsible for taking care of two grandparents as they neared the end of their life. I wasn't prepared for how difficult life can become in the last few months. Both my grandparents had nursing staff come to the house to help them with bathing. It was always extremely difficult since their bathrooms where not fully accessible. When I built my bathroom one of my paramount concerns was making it fully accessible so if I ever am in the same condition the nurse will have lots of room to just wheel me into the shower and we can both have our space. The shower door is a few inches wider than normal so that a wheel chair will easily fit through, the glass company took a while to source the extra heavy duty hinges required and where a little grumpy about my request. The hardest part about the construction was I made the shower curbless, very difficult considering I didn't raise my bathroom floor. Also the volume controls I mentioned above have square handles (1/4 turn), so when I am elderly I will have no problems.
The big home automation project in the bathroom was the mirror, had lots of fun with that, still having fun. Running it off a Pi, currently trying to get it to show a video of last nights hockey highlights, the first time in the morning the Jasco zwave light senses motion. LOL
