Van Conversion - Building The Bathroom Walls

Next up within my van was to install the walls for the bathroom. 4 had to be installed, two on either side so that when i fit a door, i have a 6 foot long shower/toilet and sink room. This was not an easy task! In order to save money I only had one shot at each cut, or it'll be another trip to a lumber yard for more costly wood. I used 12mm plywood for the walls.

First job was to spend quality time ensuring my template was accurate. Scribing by hand is a skill within itself.
Then the template (cardboard + offcuts of thinner plywood) were laid ontop of the wall to be cut.
A bit of JigSaw action!
I finished the rough edges off with sandpaper (again by hand). The edges were glued into position with some seriously strong glue (rubberdised too, so that future vibration wasn't an issue) and with a stabilising 'L' bracket on the inner wall edge to support the glue and stop any excess movement.
The bottom and top edges were screwed into place using some batons. This I felt would be very sturdy.
Bingo! Finished. I now have a 2ft wide area for a vanity unit and sink. The LED light was pre-planned earlier in the build.
Very sturdy indeed! Glad I used 12 mm and not 9 mm, or the walls would have been just too flexible along the leading edge.
All I need now is to paint the walls white and fit the other two walls on the opposite side. Plumbing will be fitted easily after the vanity unit goes in. This although simple in appearance, was no easy task for me. Planning and drawing on a white-board definately helped.

Thanks for dropping by folks... Questions, queries and comments below please (I am no DIY expert lol)!
