The shower enclosure is framed with 2 x 2, cased with 1/2" OSB on the shower side, and 1/2" plywood on the non-shower wall sides. If that makes sense. :-)

We started by screwing a 2" x 2" member to the floor, then attached vertical studs anchored at the top and bottom.
Another horizontal 2" x 2" attached at the 4' elevation.
The non-shower side of the wall. This will be the left-hand wall of the kitchen.
Upper panel of OSB on the shower side of the forward wall. The gap at the top isn't much concern since it will be covered with FRP.
The completed shower enclosure. The FRP will be glued directly to the OSB (sides) and birch paneling (back). But that comes after all of the incoming & outgoing plumbing is installed and tested. We'll also finish the front of the tub at that time.
Looking forward, driver's side.
Looking aft, driver's side. Note the homemade butcher block between the counter/sink unit and the stove. We used 1" x 6" poplar, cut into 1 3/4" inch sections. Those sections were then stood on-end, staggered and glued with Titebond II wood glue (FDA approved for indirect food contact). The clamping process left a lot of glue exposed on the surface, so we utilized the services of a local woodworking shop -- Guida Woodworks, Inc. (map) -- they ran it through a jointer and left us with only a bit of sanding to finish the job.
