Salt Deposit
Salt Deposit is a common mineral resource in Subnautica 2, harvested from sandstone outcrops in shallow waters. It enables desalination, food preservation, and a wide range of advanced chemical recipes that gate mid-to-late-game progression.
Quick Info
How to Get & Where to Find
Salt Deposit is harvested by breaking Sandstone Outcrops, the pale layered rock formations found in shallow biomes. Sandstone is recognizable by its soft yellow hue and crumbly texture, and it tends to spawn in clusters along reef shelves and plateaus.
Uses & Recipes
Salt is more versatile than its common rarity suggests. It powers a small chemical branch that unlocks desalination, food preservation, and a handful of advanced recipes used in vehicle and base upgrades.
Tips & Strategies
Stack High Early
Salt stacks quickly because of its high drop rate. Spend the first hour after spawning to stockpile 30+ units so you never get caught without desalination supplies.
Combine With Cooked Fish
Preserved fish using Salt extends food value dramatically. Cook fish on a heat source, then cure it with Salt to keep your hunger bar filled on long trips.
Save Salt for Bleach
Bleach is a prerequisite for several disinfectant tools. Reserve Salt for Bleach crafting before spending it all on food, especially when preparing for deep dives.
Pin Sandstone Near Base
Identify a sandstone cluster within 200m of your base. Sandstone respawns, so a quick swimming loop near home keeps your Salt supply topped up indefinitely.

Frequently Asked Questions
Where can I find Salt Deposit?
Salt Deposit drops from sandstone outcrops in the Shallows, Kelp Forest, and Grassy Plateaus. The Shallows are the safest early source because you can farm them within seconds of your lifepod spawn.
What is Salt Deposit used for in Subnautica 2?
Salt Deposit is used for desalination via the Desalinator, food preservation curing cooked fish, and unlocking advanced chemical recipes such as Bleach for disinfectant tools.
How rare is Salt Deposit?
Salt Deposit is a common resource with one of the highest drop rates among sandstone outcrops. You can expect to collect 2–4 units per outcrop break, making stockpile targets easy to hit.
