bathroom knee wall plan

The bathroom space seems awkward and I decided it needed a knee wall to be able to place furniture in a more pleasing manner. I dug through all sorts of things in my stash and came up with this wainscoting that I had pre-stained. I can't even recall what the original intent was but I have enough to make it work here. This is all simply laid out, I haven't done anything yet. I did pick up a couple 3" bass wood strips to build the knee wall so I just need to make a template (for the angle on the right side) and build it. The pre-stained wainscoting will be attached to the basswood and I'll finish it with a chair rail strip.
