Best Base Locations in Subnautica 2 : Where to Build & How to Power Everything
Best base locations in Subnautica 2 ranked by depth. Complete power comparison (Solar vs Thermal vs Bioreactor), room layouts, and pro building tips.
- •Shallows is the safest first base location : abundant Titanium, Copper, Quartz
- •Solar for shallow bases (<50m), Thermal for hot zones, Bioreactor as backup anywhere
- •Build Power Storage : it prevents blackouts when solar panels go dark at night
Why Build a Base?
Your Lifepod is a cramped metal box. A real base gives you: full crafting, organized storage, vehicle docking, safety from predators, and unlimited food and power. Here's where to build and how to power it.
Best Base Locations, Ranked
Coral Gardens Early-Game Spots
| Location | Depth | Rating | Why | |----------|-------|--------|-----| | Shallows (near Lifepod) | 10-15m | ⭐⭐⭐⭐⭐ | Safest, abundant Titanium/Copper/Quartz. Perfect for your first base. | | Coral/Anemone Fields (NW of Lifepod, 100-330m) | 10-30m | ⭐⭐⭐⭐⭐ | Resource-rich, very safe, solar + hydroelectric viable. The best balanced early spot. | | Camp One (Jelly Barrens) | 20-50m | ⭐⭐⭐⭐ | Open space, food/water nearby, water currents for turbines. Good second base. | | Near Tufa Towers (E/SE 180m) | 20-40m | ⭐⭐⭐⭐ | Near wrecks for blueprints, copper cave nearby, water currents. |
Mid-Game Spots
| Location | Depth | Rating | Why | |----------|-------|--------|-----| | Near Graveyard / Hot Caves (E/SE 620m) | 50-150m | ⭐⭐⭐ | Gold, Sulfur, Lithium access. Near Karakorum entrance. Requires Heat Tolerance. | | Inside Hot Caves (under Tailings Village) | 80-120m | ⭐⭐⭐ | Infinite thermal power. Direct rare ore access. Bridge to Karakorum. |
Late-Game Spots
| Location | Depth | Rating | Why | |----------|-------|--------|-----| | Axum Observatory | 140m | ⭐⭐⭐⭐ | Central Karakorum hub, currents for power, close to Research Outpost and Coral Gardens. | | Power Plant Area (480m E of Alien Ruins) | 200m+ | ⭐⭐⭐ | Flat space, Celestine/Troilite nearby. Needs Depth Module. | | Alterra Starship Wreck (Metal Farms) | 300m+ | ⭐⭐⭐ | Direct Troilite/Bacterial Culture access. 300m deep, need advanced depth module. |
Power Systems Compared
| Power Source | Best For | Materials | Notes | |-------------|----------|-----------|-------| | Solar Panel | Shallow bases (<50m) | 2× Quartz, 1× Copper | Free, infinite. Useless at night/depth. Build 3-4. | | Hydroelectric Turbine | Bases near water currents | 2× Titanium Ingot, 1× Copper Wire, 1× Glass | Needs Power Transmitters. Best for mid-depth bases. | | Bioreactor | Any depth | 2× Titanium Ingot, 2× Copper Ingot | Needs constant fuel (plants/fish). Good backup. | | Thermal Plant | Hot zones (Graveyard, Hot Caves) | 3× Titanium, 2× Gold, 1× Sulfur | Infinite, stable. The best power source, but location-locked. |
Rule of thumb: Solar + Bioreactor for shallow bases. Thermal for hot biomes. Hydroelectric is great if you happen to build near a current.
Base Building Order
- Room (5× Titanium), Your first enclosed space.
- Hatch (1× Titanium, 1× Quartz), Entry/exit point.
- Solar Panel(s) (2× Quartz, 1× Copper each), Power.
- Fabricator (1× Titanium, 1× Copper, 1× Quartz), Full crafting access.
- Wall Lockers, Storage. Build at least 4.
- Battery Terminal (2× Titanium, 2× Quartz, 1× Copper Wire), Recharge batteries.
- Moonpool (5× Titanium), For Tadpole docking (mid-game).

Pro Base Building Tips
- Hub & Spoke model: One main base + 2-3 small forward outposts (1 room, 1 Moonpool, 1 charger, 1 locker).
- Structural integrity: Keep at least 10 points above zero. Glass windows and hatches cost integrity.
- Never rely on one power source. Solar + Bioreactor is the safest combo for early bases.
- Floor lockers hold 30 items, place them sideways against walls for maximum density.
- Grow food in your base. Plant edible flora in growbeds so you never have to hunt for meals.
- Build near resource clusters. You'll be making dozens of supply runs, minimize travel time.
