I am just about to take the plunge and order a completely new
bathroom.

I am going for a steam room.

It's about 5 times the size of a conventional shower unit and has a
seat. It electrically heats water from the cold supply to generate
steam. The unit is all digitally controlled.

I have found a local company that fits nothing but bathrooms. They
have about 15 different types of steam cabinet in their showroom.

Has anyone had any experiences with steam cabinets in the home?
