To get the underwater bed in Grounded 2, defeat a Diving Bell Spider in the pond, collect a Diving Bell Spider Chunk, then analyze it at a Resource Analyzer to unlock the Diving Bell Bed recipe.
The underwater bed in Grounded 2 is the Diving Bell Bed. The August 11 Into the Abyss update opened Brookhollow Park’s pond, added underwater base building, and gave players a bed built for sleeping below the surface. To unlock it, kill one Diving Bell Spider and scan its chunk.
The underwater bed is the Diving Bell Bed
The item players mean when they search for an underwater bed is the Diving Bell Bed, a sleeping spot you can place below the water’s surface. It isn’t a quest reward or a shop unlock — it’s a Resource Analyzer recipe from a single monster drop. Kill the right spider, scan what it drops, and the recipe is yours.
How to unlock the Diving Bell Bed in Grounded 2
Key This route takes you from the pond dive to the recipe unlock, and the whole job takes about a minute of in-game work.
Head to the pond
Go to the water opened by Into the Abyss, aiming for the pond near the bridge and the big tree at the water’s edge.
Find a Diving Bell Spider
Dive under and search the aquatic plants. Diving Bell Spiders live down in the pond biome and turn up in numbers.
Defeat the Diving Bell Spider
Fight it underwater, using the update’s new swimming lock-on and Burst dash to stay on target while you trade hits.
Collect the Diving Bell Spider Chunk
The kill drops a Diving Bell Spider Chunk along with some Web Fiber, so grab the chunk before you resurface.
Head to a Ranger Outpost
Swim back and step into any Ranger Outpost — you don’t need one specific location for this.
Scan the chunk at the Resource Analyzer
Analyze the Diving Bell Spider Chunk at the Resource Analyzer to unlock the Diving Bell Bed recipe.

What analyzing the Diving Bell Spider Chunk unlocks
| Unlock | Use |
|---|---|
| Diving Bell Bed | Sleeping and respawn point for a submerged base |
| Liquid Gills | Underwater gear unlocked from the same chunk |
| Diving Bell Wall Mount | Wall-mounted trophy for base decoration |
| Stuffed Diving Bell Spider | Standing trophy for base decoration |
That single scan gives you more than the bed. Put the Diving Bell Spider Chunk into the Resource Analyzer and you unlock a small set of Diving Bell recipes at once, covering the sleeping spot and a few base extras with one kill.
You only need one Diving Bell Spider Chunk — a single scan unlocks the bed and three more recipes together, so there’s no reason to farm the spiders for multiples.
Using the Diving Bell Bed in your underwater base
The Diving Bell Bed exists because Into the Abyss added underwater base building, letting you raise fully submerged outposts down in the pond. A submerged base becomes a real home once you can sleep and set a respawn there, and that is exactly the bed’s job.
Key Drop it inside a sealed underwater build and your spawn point moves below the surface, so a deep expedition doesn’t end with a long swim back from the shore every time you go down. Use it as the anchor for a submerged staging outpost near your dive sites.
Gear up before you dive for spiders
Before you go spider-hunting, kit yourself out for a real dive. Into the Abyss builds its progression around oxygen and depth — the new Diving Suit lets you stay under longer and reach the deeper, otherwise out-of-reach stretches of the pond, and finding Optical Disks unlocks upgraded Diving Suit recipes for pushing even further down. Bring underwater-ready gear and enough air before you start the fight, since the Diving Bell Spider waits in the water, not on dry land.

Frequently Asked Questions
Can you sleep underwater with the Diving Bell Bed?
Yes. The inside of an underwater base is still flooded rather than pressurized, so a normal bed would drown you mid-nap — the Diving Bell Bed is built to be used down there. Pair it with a Bubble Diffuser to keep your oxygen topped up while you rest.
Where do Diving Bell Spiders spawn?
They’re a pond creature. You’ll find them underwater among the aquatic plants, and they appear in groups around the water near the bridge and under the big tree at the pond’s edge.
Do you need a specific outpost to analyze the chunk?
No — any Ranger Outpost with a Resource Analyzer works. It’s the same station you use to break down any new material into recipes, so whichever outpost sits closest to the pond saves you the longest swim back.
