I think what I see here is a rain of the future, but the modern day showers are designed for a small room. This cocoon “shower” is definitely in a bath where there is enough space.

In fact, this shower is more than just a shower, because you might not be able to tell from this picture. Apparently the basis of this cocoon shower is big enough for a bathtub cocoon, and not just a bath, but a hydro-massage.

Still be somewhat unclear, that could contribute in this image is the “curtain” on this thing. It opens like a flower, and the curtain slides in the entire structure.

I believe my source mentioned that resembles meditation room of Darth Vader from The Empire Strikes Back, and I can not help but agree with her when she was painted black. Perhaps that's where the storm troopers come to pray to assume that these clones meditate.

This shell Cocoon is just a bath of Arina Komarova designed, and it is not for sale. However, as I too think that items such as this help to turn dreams into reality. So if you want to shower this cocoon, then you must speak with one voice, until you get it.
