The old porch of our 1898 house was converted into a bathroom, which is great, but means that we walk through the bathroom to get outside...sometimes resulting in unexpected surprises when we have a backyard BBQ.

To solve this, we want to section off the porch into a bathroom area and a mudroom area by framing out a wall. We'd like to keep our 3 piece bath (toilet, sink, shower). Is it possible to fit a shower, pedestal sink and toilet in a 37.5" x 94" space (inside dimensions, framing and dry wall already accounted for)?
