Why bother with a seaside massage when you can have an under-the-sea massage?
Huvafen Fushi, a luxury resort in the Maldives, is home to what it claims is the world's first underwater spa. The spa, named LIME, has added new treatments like Lose It, Tone It; Cellulite Therapy and Stress Buster.
There are also above-water treatment rooms for those who would rather be pampered above sea level.
The underwater treatment rooms took 12 months to construct and are made of a solid-cast resin to create an underwater structure that could be set in the open ocean with minimal disturbance to the ecosystem of the Maldives. The resin is five inches thick, which, the hotel said, "provides infinitely better clarity than the cheaper option of laminated glass."
The Maldives is also home to the world's first underwater restaurant: Ithaa at the Conrad Maldives Rangali Island. The restaurant is 16 feet below sea level and has 180-degree views of reef and marine life.
In Dubai, plans for an underwater hotel are in the works. Current designs call for the sleeping rooms to be underwater but the common areas to be above sea level. The design is comprised of discs, some located nearly 100 feet beneath the surface of the sea. Each is composed of 21 hotel rooms adjacent to the underwater dive center and a bar.
