Underwater Glass Dome

A Glass Dome is a wonderful idea for an underwater base since it allows you to enjoy the amazing scenery under the ocean. You can mix it up and add some other material into the build as you wish. Get some jack o'lanterns, glowstone, or sea lanterns to light up the space around your base.

Underwater Mountain House

Now, this is kind of a special underwater base since the base doesn't really submerge into the water. Your base is technically inside a mountain with a view looking into the ocean through the glass. The access to your base will be through the mountain instead of having underwater access.
