Selecting pianos and customizing at a factory question

[irrational]

Hi.

I was wondering, after browsing through several manufacturer's websites, about the selection process of a new piano.

Many pianists here indicate that they go to a showroom or factory and select a piano there.
But manufacturers also have customized casings etc. for the pianos.
So I was wondering how the process works.

For instance, say you want a Vienna design Bosendorfer, which comes in all sizes, or a Crown Jewels Steinway.
Would you choose a suitable piano and then the casing gets updated to the new specification (which I assume could have noticable effect on the sound).
Or is a whole new piano crafted? In this case, what if you are not happy with the action or sound?
I would assume that there won't be a large selection of these special designs to choose from and they are largely made on request?

Just curious.

Once a piano is manufactured, that's the end. It won't be modified to become a showpiece.

The custom-carved versions are built to order. You won't find them on the showroom floor.
