'Empty-nesters' restructured their home to better accommodate their new lifestyle. The master bathroom was completely renovated to replace the never-used corner tub with a steam shower (including rain head). Natural light floods the space via both glass block (in the steam shower) and the Solar Tube skylight. Melanie Hartwig-Davis (sustainable architect) of HD Squared Architects, LLC.
