Bath

Strongly contrasting colors were used to differentiate bedrooms and bathrooms. The master bath is awash in reddish hues with a custom freestanding vanity by Studio Bright.

Inax Yohen Border tiles from Artedomus line the master bathtub.

The brass fixtures are from Gessie’s GOCCIA series. Brass borders add "a sharp edge to the tiled, curved spaces." The scalloping appears in this space on a large deconstructed scale as well as in the curved detail of the floating vanity.

The showpiece in the new bathroom is the floating vanity with an integrated sink carved from a block of Nero Marquina marble.

Made from injection-molded BluStone - a durable quartzite that's nonporous, anti-microbial, and stain- and scratch-resistant - the tub is available in a glossy or matte finish.

The shower is covered in Cottonwood mosaic and penny tiles by Ann Sacks.

New plantings provide privacy for the glass-walled shower in the master bathroom. The matte black fixtures are by Phoenix.

A large en suite bathroom adjoins the principal bedroom, featuring bright-white walls that reflect natural light and high windows that frame the sky.

Antonio designed and made the Perspex towel rack in the bathroom when he couldn't find one that suited the space. The Polo stool by Anna Castelli Ferrieri for Kartell is from Bi-Rite Studio in Brooklyn.

Quarry Pavers from Seneca Tiles cover the bathroom. All of the fixtures are from Sigma, and they were originally chrome before Grey stripped and refinished them.

Large-format wall tiles create organic texture in a neutral color, consistent with the the rest of the house.

The kids' bath is playful while adhering to the home's overall color and material palettes.

Since the couple think of the addition as an “extrusion,” they “carried that theme to the rest of the house with the vertical fixtures on the stair and the vertical slats in the bathroom vanity,” says Jason. The marble sink basins are from Stone Forest. The custom shape of the mirror swirls around lights from Rich Willing and Brilliant. Faucets from Rejuvenation are mounted on white oak backplates inset into the slats.

The shared second-floor bath has a black tile backsplash that references the home’s shou sugi ban siding. The oak and cold-rolled steel vanity echoes the design of the kitchen’s furniture-like island.
