A major ventilation issue was the lack of humid air vents in the two bathrooms. The guest bath window suffered from mold issues. The window was replaced with the fiberglass / fir veneer sealed with polyurethane, and ultra-quiet fans were installed in each bath/shower area, and ducted to a point under the eaves, but well below them. Despite the fact that it would have been easier to exit the house right at the master bath, about 6² below the eave, the duct was routed closer to the guest bath so it was entered on roof peak, but set far below it.

Master bathroom, vanity and the small footprint sink
In the bathroom vanity area, space issues were prominent. The vanity and closet area measured 5 feet by eight feet, with only 5 feet available for a vanity. A desire to accommodate two sinks and maximize storage space led to minimal footprint sinks (15 inches wide) and faucets, and storage drawers under the sink plumbing. Cabinet thickness was narrow at 20 inches, and height was set to 36 inches (plus counter thickness), to reduce splashing in an adult bathroom. Later remodels of the shower area will open up the wall on the right for a corner shower, reducing the intrusion of that wall into the space, a new single outswing door to the exterior replacing the small slider, and a pony wall next to the toilet, allowing more light into the master bath.
Materials choices for the cabinet were all-ply construction, cherry finish (cherry door fronts), and less-toxic polyurethane finish, sprayed on. The small countertop was seated with caulk, rather than the glues often used.
