Dan Mazzarini spent more than seven years at Polo Ralph Lauren, designing stores for the fashion empire, before he started his own firm, BHDM Design, in 2012. Flywheel Sports, the cycling gym that launched in Manhattan in 2010, sought out Mazzarini to help with a 3,400-square-foot ground-floor space in Williamsburg, Brooklyn. It would serve as a design testing ground for Flywheel studios going forward.

Mazzarini used a series of neutrals throughout. In the locker / shower room, black ceiling and 2 x 8 matte-white porcelain wall tiles with contrasting gray grout have a fashionably graphic effect–nicely shown off by gray slab flooring.
