I opted for FRP panels for this build. My plan to use this trailer for just a few years makes these panels easier for resale as a work trailer. I like neutral colors so I picked grey for the walls. The ceiling of the trailer was already completed. I used Behr premium paint and put two coats of white on the walls and then floated the FRP panels. In each section I have enough things to hang so I don't need to glue this down.
The bathroom is shaping up nicely and I added the extras just for the photo. The curtain partitions come later in the project.
