The primary suite boasts a large walk-in-closet that leads into a five-fixture bathroom with a custom double sink vanity complemented by Watermark oil rubbed bronze fittings, heated marble floors, a 6' Kohler bathtub, a glass-enclosed shower, and water closet by Toto. White oak wide plank flooring (5.5" to 9.5"), central heating and air cooling and a washer and dryer complete this residence.
