After traveling the world and having three kids, these homeowners were ready to settle down in their forever home. They asked designer Taylor Harrison to create a second-floor addition that includes an elevated yet kid-friendly hallway bathroom for their young son and occasional overnight guests.

Harrison responded with an efficient setup in 70 square feet that includes a hardworking single-sink vanity, a toilet and a roomy low-curb shower. The couple referenced inspiration photos they saw on Houzz when deciding on a fresh and clean style. Glazed blue-gray ceramic wall tiles wrapping the shower complement the blue-green paint on the vanity. Large-format matte white porcelain floor tiles and white walls help reflect light and visually expand the room. A gray quartz countertop and matte black plumbing fixtures and other details lend a touch of modern flair.
