What is the deepest underwater hotel in the world?

Hydropolis, Dubai Hydropolis is an underwater hotel being constructed 20m (66 feet) below the surface of the Persian Gulf, just off the Jumeirah Beach coastline in Dubai. Designed by Joachim Hauser and Prof. Roland Dieterle, the luxury hotel is set to be the world's deepest underwater hotel upon completion.



As of 2026, the Lovers Deep St. Lucia Submarine is technically the deepest and most mobile "hotel" experience, allowing guests to submerge deep into the Caribbean Sea. However, for a stationary, permanent structure, the Jules' Undersea Lodge in Key Largo, Florida, remains the most famous, requiring guests to scuba dive 21 feet (6.4 meters) down to enter their room. Many travelers often look toward the InterContinental Shanghai Wonderland, which features "underwater" guest rooms built into an abandoned quarry, or the The Muraka at Conrad Maldives Rangali Island, which sits about 16 feet (5 meters) below sea level. While there have been ambitious proposals for deeper hotels like the "Hydropolis" in Dubai or the "Poseidon Undersea Resort" in Fiji (intended to be 40 feet deep), most remain in developmental limbo or as high-concept renderings. For those seeking the "deepest" experience currently available, the submarine-based hotels offer the most literal interpretation, while the Maldives and Shanghai provide the most luxurious "sub-surface" views of marine life from the comfort of a stationary bedroom.
