While many homes above the $10 million mark in Ontario are known to come with their own saunas, wine cellars, multi-car garages, and outdoor pools, this $25 million mansion in Kingston blows many of them out of the water with its personal two-lane bowling alley. 

Located at 81 King St. E., this iconic mega-mansion was constructed in 1841 by John Watkins, a wealthy merchant who made much of his fortune building houses in Kingston. 

Situated across from the historic City Park and steps away from Lake Ontario, the residence has since undergone an extensive four-year restoration, which has ultimately secured its status as Kingston's most prestigious address. 

The half-acre lot is accessed through wrought iron gates, with its exterior showcasing ornate woodwork, ironworks, and handmade masonry. Landscaped gardens and a roundabout driveway lead you to the home's front door. 

Inside the historic mansion, you'll find an impressive two-storey library, illuminated by a 20-foot window and a 900-pound Austrian crystal chandelier. 

Hundreds of books line the walls of the library's second floor, which can be accessed via a cast iron staircase imported from Italy. 

The home's gourmet kitchen (which also happens to be two storeys) features a stone wall, fireplace, wood ceiling beams, as well as Sub-Zero appliances. 

The mansion also boasts five primary bedroom suites with private baths, a spa retreat in the cellar with a hot tub, sauna, and massage area, a three-car heated carriage house, and a wood-panelled elevator. 

The historic property's most unique selling feature is undoubtedly its fully automated two-lane bowling alley imported from Germany. 

The entertainment space is also complete with its own storage area for bowling shoes and an on-brand vending machine stocked with snacks and drinks. 

Moving outdoors, the original two-storey stable on the property has been transformed into a rustic oasis with a heated saltwater lap pool accompanied by lounge chairs. 

As expected, having your own personal bowling alley comes with a hefty price tag. This mansion is currently on the market for a mind-boggling $25 million.
