Whilst I agree with you regarding the the WBP ply, I don't agree that tile adhesive will fail. What's your thinking behind this?giselle - 1/2" exterior ply, tiled to match those on the bathroom wall. Fix tiles with Gripfill adhesive (not wall-tile adhesive 'cos it will fail), grout when dry, hold panel to underbath framework with mirror screws - those chrome domed ones. It'll look brill.
Photo opportunity.just made my own bath panel
top/bottom rail 3x1" 2 intermediate and 2 outer styles 4x1"[door on its side]
3 panels 2x1" 10mm wide rebate 12mm deep outer edge 9mm deep internal rebate for 12mm ply protruding out the back 3mm but chamfered
all edges with a small roundove[quarter round ]
the frames stick out 9mm with the ply 4mm further back
the panels are held in place by a lip at the top and gravity/friction/rubber seal at the bottom
this allows a realy nice looking bath pannel with lots of storage space and instant access to the plumbing

Also recommended is to seal the back of the ply to reduce warping with moisture.
