The Bathing Porch

A 1913 Colonial Revival house in Southwest Portland, Oregon, recently went through a restoration that turned an old upstairs sleeping porch into a bathroom. Sleeping porches were screened rooms once used for fresh-air sleeping, common in older homes, and this one sat behind large windows and Ionic columns on the home's gabled end. The design/build firm Arciform converted it into a primary bathroom and closet with a handmade-tile floor, a brass soaking tub, and brass console sinks topped with marble.

The bigger point for anyone with an old sleeping porch is a practical one: these rooms were built lighter than the rest of the house, since they were meant as outdoor-adjacent spaces rather than fully conditioned living areas. Turning one into year-round living space, especially a bathroom with a soaking tub, means updating the framing, insulation, and floor structure, and adding proper heating, cooling, and weather protection. This particular house is listed on the National Register of Historic Places, so the renovation was done carefully to preserve the original architectural details while making those structural and mechanical upgrades.

If you have an old sleeping porch or similar lightly built addition, the takeaway is that converting it to a full-time room isn't just cosmetic. It usually calls for real structural and insulation work before you can rely on it as comfortable, code-ready living space in every season.
