Thank you for the comment and question. In this bathroom, the electrical receptacles were kept off the corrugated walls. They were set in the back splash and sides of the vanity cabinetry.

I guess if you wanted to have electrical switches, plugs, sensors etc, one way would be to do them via galvanized electrical boxes with galvanized face plates, the boxes cut thru the corrugated siding with the face plates riding a bit in front of the corrugations. This would be basically doing the electrical as if it were running in a metal conduit system.

Hope this is helpful. Glenn

Thank you, I appreciate it!

What did you use for the magazine rack here?

It is a commercial stainless steel paper towel receptacle such as those made by Bobrick eg https://washroominc.com/product/bobrick-367-60-classicseriesr-interchangeable-receptacle/
