This was a custom designed and fabricated steel pivot door (all the doors on the house match).

It shows skill in craftsmanship and design. What a great element.

Thank you! I agree it makes a big difference in the space.

then what is marble style and cut and application on floor? they look very odd size is it calcutta it has the bluish dining in it there are synthetic material looks just like this made in large tiles is that what thesis? i thought those were only for wall application or surrounds not floors- porcelanosa makes large ones these look like 18z36?

The floor is Arabescato slab marble (roughly 7/8" thick) cut into panels to work with the slope of the floor. The material comes in large slabs that are then fabricated to a specific joint layout in the bathroom and into the shower.
