Seabases

Subnautica's seabases are created through the use of the builder, created by the Fabricator.

"[Seabases] are available now, and allow the construction of habitats on the sea floor. Bases are composed of modular units such as compartments, windows, and hatches, bases allow you to create an outpost from which you can go forth and explore Subnautica’s vast ocean."

Seabases can be customized in the same way as the Cyclops through the installation of lockers; fabricators; and fragment analysers.

Special Properties: Hull Integrity
Hull integrity refers the ability of your Seabase to withstand the pressure of the surrounding water.

Hull integrity can be increased through the use of special items called reinforced hull.

Factors that effect hull integrity
 * Number of interconnected modules
 * Windows
 * Depth at which the seabase is built

Requirements for All Seabases

 * Flat terrain
 * Builder
 * Foundation (crafted through builder)
 * Power Generator (crafted through builder)
 * Hatch to allow entrance to seabase (crafted through builder)
