231 Dune Rd

The Ocean Resort Bath & Tennis is a single-story, century-era resort complex on Dune Road in the Water Mill/Westhampton Beach area, dating to 1920. Configured largely as one-bedroom co-op units and efficiency studios, residences commonly feature cathedral or high ceilings, skylights, first-floor primary bedrooms and baths, eat-in or galley-style kitchens, and private balconies or waterside decks overlooking marina and bay views. The property is organized around resort-scale shared spaces: a large heated saltwater pool with attached kiddie pool, private sandy ocean beach with staffed towel and chair service, multiple tennis courts, marina slips with seasonal dockage, a spa and fitness center, on-site restaurant and tiki bar, and concierge/valet services. Housekeeping, laundry services, weekend shuttle to the village, and a business center supplement full-service operations. Parking and valet are available; some units are offered furnished and rentable under the co-op’s program. The complex’s low-rise massing, historic origins, and resort programming create a coastal vacation-residence atmosphere within walking distance of Westhampton Beach’s shops, restaurants, and performing arts venues.
