Here's a few photos of the latest work. The starboard wall is finished, the shower head plumbing is installed for the wall-side shower head (there will be 2, one on each side of the shower), the rear wall is now covered in luan, and about half of the front wall is installed. The project is moving along nicely! Here's a few pics...
This is part of the spray foam system (Froth-Pac) we bought to do the interior insulation.Here's the shower valve and piping for the spray head. You'll notice the "T" and piping going up the wall. That will go to another shower head on the opposite side. As opposed to spraying from the center towards the shower curtain, or from above, small heads on either side will spray and hopefully keep most of the water in the shower stall.
