Wondering if a double pocket door is an option for our upcoming bathroom renovation. The opening is 81 1/2" tall from the tile and 34 1/2" wide. The wall is currently 5" wide. There is a support beam above the opening, leaving only about 3 1/2" above the arch, so I'm not sure if there would be room for the frame.

I would like to tile around the arch, so there might be an opportunity to adjust some dimensions?
