This 17,775-square-foot home in Lake Quivira, Kansas, seems pretty spectacular from the outside, but just wait until you find out what’s underneath the property: a wonderland for scuba divers.
The home was owner Dennis Langley’s personal water park before he passed away in 2017. “(He) was just a scuba enthusiast and a fun-loving man from all accounts," realtor Katie Casey told TODAY Home. His wife is currently selling the home for $11.8 million.

Built in 1993, the massive mansion named “The Spirit of Avalon” was remodeled when the current owners purchased it. Some of the cool features they added? A grotto, waterfall and scuba tunnels!

The new residents can cliff dive from a 30-foot waterfall into a pond that's more than 30 feet deep. The pond also includes statues, fossils and shells that are carved into the walls for divers to spot. Inside the grotto, you’ll find a heated indoor pool, shower and bathroom, wet bar, hot tub and sauna.
Then there’s the scuba tunnel that goes from inside the grotto out to the pond and a number of underground tunnels that go out from the pond. And just in case you get stuck, there are some emergency pop-up holes inside the tunnels. Safety first!

Inside the home, a breezeway room connects the library to the main house. The room has an indoor waterfall and glass tiles in the floor where you can see a creek that runs under the home. “I have been told that otters used to play in those features and you could see them swimming under the floor,” Casey said.
Of course the home won’t just appeal to water lovers.

There’s an insanely gorgeous two-story library boasting ornate stained-glass windows. And the turret on library is reported to be the highest point in the county, according to the real estate listing.
Other special details include hand-carved dragon doors and a pulpit from Salem.


And the home is definitely made for entertaining. It has a huge theater and billiards room, multiple wet bars, a wine cellar and lots of indoor and outdoor spaces to lounge with guests.

You’ll feel like royalty when you retire to the master suite which has its own private sitting area, breathtaking views from the wall of windows and a fancy bathroom with a whirlpool tub — you know, in case you tire of swimming around your house but still want to relax in water.
