Classic architectural details that lend charm to a 100-year-old house can be a mixed blessing. The beauty of Tudors is that there are lots of rooflines coming together, but when you get to the interior, there’s a challenge with headroom and how the space functions. For a master bath in this 1920s Larchmont home, all the angles were worked to meet the homeowners’ wish list, turning a cramped closet into a chic shower stall and devising solutions to maximize space. The clients’ priorities included a large shower stall, a double vanity, linen storage, and a tub. From a style standpoint, they wanted something modern and distinctive.

Building this new master bath, with an adjacent walk-in closet, called for creative repurposing of rooms: They combined the space of their old closet with their daughters’ old bathroom to create the couple’s new bath and closet, then added a new bath and closet for the girls. One side of the sizeable shower is nestled into a sloped nook, an ideal spot for a built-in bench (less headroom needed) and niches to store shampoo and other products. Frosted glass between the shower stall and toilet lets in light from the window while offering privacy. On the shower floor, there’s an infinity drain that enabled a seamless install of dark, brick tiles: a modern touch that’s a nod to hotel bathrooms.

A soaking tub fits perfectly opposite the vanity, thanks in part to its top-mounted fixture (there were no inches to spare for floor-mounted hardware). Pocket doors leading to the bedroom and closet are also major space savers. While the vanity with linen tower looks custom, it’s actually two pieces of cabinetry in a cobalt blue.

The subway tiles have a subtle blue glaze at the edges. And the blue hue is picked up in the trim on the Roman linen window treatments. White walls and ceiling and the quieter white subway tiles offset the strong visual interest of the vanity and the boldly patterned floor tile that anchors the room. Mirrored medicine cabinets, trimmed in black steel, reflect the windows, making the room look bigger and more light-filled. Mixed hardware tones of brass and black really tie the room together: The drawer pulls and light fixtures add brass accents, while the tub and sink hardware and shower stall have a black metal finish.
