1. PlacementAccess. Choose a spot for your vanity that won't mess with your bathroom's traffic flow or block the bathroom door or shower door swing. Beth Fillerup of Native Trails advises homeowners to think about cleaning and about the vanity door swing space, too. Good questions to ask, she says, include: "Are the surrounding areas accessible for cleaning? If the vanity has doors, is the space around the vanity adequate for foot traffic when they are open?"Designer Robert Berkovich of European Cabinets & Design Studio suggests that homeowners take other architectural features into account when deciding on a spot, too. Make sure that any windows nearby will allow for a mirror and wall cabinets above the vanity. "Remember, the vanity plays an integral role in the function of the bathroom and requires the space around it to function properly," says designer Steve O'Neill of Van-i-tY.
