These are existing or planned underwater hotels where you can literally "sleep with the fishes". There were more of them, but these are often ambitious technical projects that struggle to get off the ground... or rather, under the water.
Poseidon Undersea Resort

Not yet built. The original plan (2006) was to build a Poseidon resort 16 metres underwater off the island of Eleuthera in the Bahamas. Now the location is slated to be a private island in Fiji. The modular plan is for around 20 air-conditioned, humidity-controlled pods with reinforced transparent walls, each a 5-star luxury suite, reachable by lifts from the surface. Guests will be able to lie in bed, or in a jacuzzi, and watch the marine activities on the surrounding reef. Other facilities in the original version included a revolving sea-floor restaurant, a library/lounge/conference room, and for certfied divers, a lock out chamber and moon pool combination so that they can go for a swim around the hotel grounds.
Utter Inn

A single (quite nicely decorated) room suspended under a pontoon 1km out in the middle of Lake Mälaren in Västerås, Sweden. The floating pontoon has a small hut and a deck from which to fish, swim, kayak, etc. You climb down a ladder to the bedroom which contains only twin beds and a table. Meals are delivered by boat. It doesn't have a website but Unusual Hotels of the World sell it and The Guardian has been there.
Update: They do now have a site for the underwater room concept and have opened a new one off Zanzibar. See Manta Resort (above).
Jules' Undersea Lodge

Florida Keys
The original underwater hotel, and still going strong. The air-conditioned 'hotel' located just of Key Largo is the size of a large caravan. It has two bedrooms, a kitchen, toilet, shower, and plenty of creature comforts such as books, VCR, stereo, etc. The only downside is that you have to be a certfied diver to stay there because to get to it you need to dive down 21 feet and enter through a moon pool opening at the bottom of the habitat.


  • The Niyama resort in the Maldives has opened (Oct 2012) a new undersea nightclub. Subsix lies half a kilometre off the beach and six metres underwater. On the surface there's a restaurant and bar.
  • Conrad Maldives Rangali resort has an all-glass undersea restaurant (opened in April 2005 when it was a Hilton). The Ithaa restaurant sits 5 meters below the waves of the Indian Ocean, surrounded by a coral reef and encased in clear acrylic offering diners 270-degrees of panoramic underwater views. It is reached by a wooden walkway from the nearby over-water Sunset Grill Restaurant. Diners begin their meal with drinks on a specially constructed deck over the ocean and then descend to the restaurant via a spiral staircase where the à la carte menu is served. The 5 x 9-metre transparent arch, which spans the entire room, seats 14 people and is set with the resort’s reef one side, and a clear lagoon on the other.
  • Huvafen Fushi resort in the Maldives has an underwater spa. The resort is built over its on lagoon and two of the spa's eight treatment rooms are underwater.
  • The French architect Jacques Rougerie constructed three underwater habitats between 1977 and 1981, though none ever made it into the water. He has also designed an undersea village for the Virgin Islands that has yet to be realised. (He is currently working on SeaOrbiter a giant drifting buoy with pressurised accommodation for 18 crew & researchers. 31 metres of its 51 metre height will hang below the surface. Its first mission, in the Gulf Stream, is scheduled for 2008.)
  • Hydropolis. There was a plan in 2006 to build an entire underwater hotel complex off Jumeirah Beach in Dubai called Hydropolis. It was delayed in 2008, and the project, along with many others in Dubai since the economic downturn, looks unlikely. A shame because the hotel resembled the underwater alien shapes in the sci-fi movie 'The Abyss' (its German designer called the architectural style "Biogenetic"). It was designed to sit half underwater and half exposed in its own 20-metre trough, connected to a reception building on the land by an electric train running in a tube. In addition to the 220 suites each costing around £3,500 per night, the complex would have housed several restaurants, a ballroom, a cinema, conference facilities, a cosmetic surgery clinic, and a spa specialising in hydrotherapy treatments. The above water exterior sections which would have provided artificial beach platforms, swimming pools and bars would be hidden from prying eyes by a curtain of waterfalls, that would also generate a fine mist helping to reduce the temperature around the hotel. A 2010 Gizmodo post has some images.

    In April 2006 the China News agency reported that an underwater hotel was planned to be built in 2009 in Qingdao, a city of Shandong Province in North China, by the same company, Crescent Hydropolis Resorts. This hotel would have combined public rooms and facilities on land (60%) with 390 suites, a spa and rotating restaurant up to 25 metres underwater. There is no news on the state of this project.
  • An underwater, or at least partially underwater, casino resort called 'City of Dreams' was planned for Macau in 2008, by a local casino company, Melco International Development. The resort would have had have three hotels totalling over 2,000 rooms, a theatre complex and an underwater casino. That project has gone quiet too.
