Plans have been released for the world's most luxurious submarine which can dive as deep as 328 feet underwater for up to seven days at a time.
Dubbed the Deep Sea Dreamer and shaped like a fish, the sub features a viewing orb - fitted with recliner chairs - to explore the breathtaking ocean views.
The groundbreaking vessel can cruise underwater for up to 100 miles, powered by a silent, electric motor which doesn't disturb marine life.
Thanks to the onboard batteries, it is able to remain stationary on the ocean floor for up to seven days, offering a rare chance to experience seabed serenity.
The concept, created by California-based Steve Kozloff Designs, is fully operational both above and below the water, boasting a 2,440 square feet observational deck upon resurfacing.
The luxurious interior extends across two levels, offering 1,500 square feet of living space and enough room for a gourmet kitchen and laundry room.
There is a large master suite, complete with an en-suite bathroom and walk-in closet space. Guests are offered their own cabin, with private bathroom facilities.
