Hello, Vicky. Thanks for your interest in the project. Not sure which white wall you are referring to but perhaps the wall under the orange glass splashback? That is a solid man-made stone product. Hope this helps and good luck with your project.

Hi, is the solid man-made stone wall below orange inset a one-piece. Or is the top counter separate from the wall? Is it something like white silestone or quartz?

Hello, kvs9.

It is a quartz type product applied to a hob, if that makes sense. Bit like a benchtop but vertical.

Hope that helps.

Thanks so much for your reply! Beautiful bathroom with an impeccable finish.
