01 mosby bathroom addition

The family loved the home they bought in Clayton, MO except for one thing – there was only one bathroom on the ground floor. Longing for a master suite, they enlisted Mosby Building Arts, who created the solution to build a bathroom and walk-in closet room addition to the rear of their home, thus turning their bedroom into a master suite.

There was plenty of room in the backyard (shown above) to build a 13 x 13 foot addition. City ordinance requires additions to match the existing house, so the bump out is clad in a brick that seamlessly matches the original brick. A bonus benefit of the addition is that it creates a lovely courtyard on their back patio with its outdoor kitchen and dining area.

Inside the master bedroom, what was once the window (above left) becomes the entry to the bathroom addition (above right). The existing closet and original flooring and molding of the 1947 home remain in place, though new paint and a wood floor refinish refine the look of the room.

Above is the Mosby floorplan for the master bathroom addition, and it shows how the designer divided the space for optimal function. Flanking the entry are his and hers vanities at opposite ends of the room, and the shower and water closet are across from each other, as well. This placement creates a path to the walk-in closet which also mimics opposite sides for him and her, and has a window overlooking the beautiful backyard that also sends natural light into the bathroom.

The team at Mosby created a sophisticated look, starting with Earl Grey wall paint from Jeff Lewis serving as contrasting backdrop to white cabinetry and trims, subway tiles in the shower, and sink backsplashes of black, white and grey glass mosaic tile. The 12 x 24 inch linen-look ceramic floor tile softly anchors room.

The Shaker-style vanities are custom-made of maple with a glacier white paint finish, and note that the HVAC air vent is nestled out of sight in the toe kick. To the left of this vanity is the water closet whose sliding pocket door has frosted glass for privacy.

This detail show shows how the quartz countertop meets the glass wall of the shower.  The sink is a Lacava Cube under mount style, with a Waterworks Highgate faucet in polished chrome.  The glass tile sink backsplash is also used in the 3-shelf shower niche. The walk-in shower has white subway ceramic tile walls and bench (whose seat matches the sink countertops), with a Carrara marble tile floor.

Slide open another whisper-quiet pocket door (this time with clear glass) to enter the walk-in closet with a thick and soft Shaw carpet floor, and white built-in shelving that matches the bathroom vanities. In the photo above is her side of the closet, which mirrors her side of the bathroom, as well.

Mosby designed and built this master bathroom addition to be completed before the family moved into their new home, so it looks and feels to them as if it’s always been there. They were also impressed with how meticulous the crew was with keeping construction debris from the rest of the home as they built the addition with a crawlspace below. This dust protection allowed them to begin moving items into the home during construction.

A bathroom addition is a good way to turn a bedroom into a master suite while keeping the rest of a home you love intact. If you’d like to explore your own bathroom addition, call the Mosby office at 314.909.1800 or contact them here.
