This cottage-style master bathroom, an addition that hugs the existing structure of this charming Jamestown, Rhode Island, bungalow, features soft blue walls, white wainscoting and built-in cabinets that flank the mirror. Lighting is installed directly on the mirror inside a built-in niche, adding to the room's cozy ambiance. Nautical-style light fixtures and beadboard paneling are among the many details that tie this room to its location and give it a breezy, coastal vibe.
