Thanks.
The part beside the tub was custom made. I drew up the plans and had a shop make it. All the parts are galvanized and bolt together, so they are easy to take apart if needed. The full length panels are from a deck/patio store. They are aluminum posts that bolt into the cement pad.
Anne you are correct it still feels light and airy, we can still see the stars in the sky, but I we not have to worry about getting out of the tub naked and being seen anymore.
