The Ancient Hot Spring is a top-tier base structure in Palworld 1.0 that restores your Pals' SAN (sanity) and Health while they relax at your base — and it delivers the highest SAN recovery of any hot spring in the game. If you are running a busy, high-workload base full of overworked Pals, this is the endgame relaxation station you have been building toward. Below you will find exactly how to unlock it, what it costs, and how best to use it.

 

What Is Ancient Hot Spring?

 

    The Ancient Hot Spring is a hot spring built with ancient technology, filled with special water infused with Paldium. In-game it is filed under the Infrastructure category, and it is designed as the ultimate comfort structure for your working Pals. Its purpose is simple but important: keep the Pals stationed at your base mentally healthy and physically patched up. A stressed Pal with low SAN works slowly, refuses tasks, and can even become depressed, so a strong recovery structure like this one pays for itself in base productivity.

 

    For reference, the structure carries the following stats: Defense 4, HP 100,000, and a SAN Rate of 2 — the SAN Rate being what makes it the best sanity-recovery option among all hot springs.

 

How to Get Ancient Hot Spring

 

    The Ancient Hot Spring is unlocked at Technology level 76, placing it firmly in the late game. Once unlocked, you build it directly from the build menu under the Infrastructure category — there is no separate workbench required, but placing it does demand a hefty Handiwork workload of 100,000 to fully construct, so bring capable Pals.

 

Here is the full build recipe:

 

Material	Quantity
Paloxite Ingot	x100
World Tree Holy Water	x10
Thermal Core	x20
Cryogenic Coolant	x20

 

 

    Note the World Tree Holy Water, which ties this structure directly into Palworld 1.0's new Sunreach and World Tree content — you will need to be progressing through that endgame material chain before you can pour the first bucket into your spring.

 

What Ancient Hot Spring Is Used For

 

Once placed, the Ancient Hot Spring serves as a recovery hub for the Pals working at your base. Its uses are:

 

• Restores SAN (sanity) for Pals — the highest SAN recovery of all hot springs in the game.
• Restores Pal Health.
• Can fully heal injured Pals.

    Because it handles both mental and physical recovery, this single structure can replace lower-tier springs and cut down on the number of separate healing setups you need to manage at your base.

 

Practical tips

• Place the Ancient Hot Spring near your production and mining stations so tired Pals can reach it quickly and get back to work with restored sanity.
• Watch the SAN meter on your working Pals — a spring with the best SAN Rate in the game is only useful if your Pals actually have downtime to use it, so keep a comfortable ratio of Pals to workload.
• Because it can fully heal injured Pals, keep this structure powered and accessible before you send Pals out on dangerous tasks or high-tier boss fights.

 

 

Running your own Palworld 1.0 server

 

    Building endgame structures like the Ancient Hot Spring is far more rewarding on a dedicated server that is online whenever you and your friends are. A hosted Palworld 1.0 server at gamever.io runs 24/7 so your base keeps ticking even when you log off, supports full crossplay so everyone can join regardless of platform, and includes one-click backups and updates so your World Tree progress and hard-earned Paloxite Ingots are always safe. That means less time wrestling with configuration and more time actually enjoying the 1.0 Sunreach content with your Pals.

 

Conclusion

 

    The Ancient Hot Spring is the definitive comfort structure for late-game Palworld 1.0 bases: unlock it at Technology level 76, gather 100 Paloxite Ingot, 10 World Tree Holy Water, 20 Thermal Core, and 20 Cryogenic Coolant, and build it from the Infrastructure menu. In return you get the best SAN recovery in the game plus full Health healing for your hardest-working Pals — a genuine productivity upgrade for any established base.
