RimWorld: How to Cremate Corpses Best – The Ultimate Guide to Sanitation and Mood Management

In Ludeon Studios’ legendary colony sim RimWorld, death is not an "if" but a "when." Whether it’s a tribal raid gone wrong, a manhunter pack of boomrats, or simply a colonist who had a tantrum in the mortar shell storage, you will end up with corpses. Lots of them.

Left untreated, rotting bodies cause three massive problems: Negative mood debuffs (the dreaded "Observed rotting corpse" stacks), Disease risk (corpses inside your base cause lung rot), and Performance issues (too many unspawned items slow the game). Cremation is the most efficient, permanent solution. But how you cremate matters. Burning a single body at a time with a torch is slow; wasting components on an electric furnace is costly. This guide covers the best strategies for vanilla RimWorld and its expansions (Ideology, Biotech) to ensure you never see that "Colonist had a breakdown because of the pile of dead raiders again" message.

Step-by-Step: The Ultimate Cremation Workflow

For 95% of players, here is the best way to cremate in RimWorld right now: rimworld how to cremate corpses best

1. Build a stone room with a stone door next to your killbox.
2. Build one Electric Crematorium inside that room (or just outside the door).
3. Create a 1x1 Dumping Zone one tile outside the door. Set: Humanoid Corpse, Fresh & Rotten, Strangers only.
4. Create a second Dumping Zone inside the stone room for overflow. Set: Humanoid Corpse, Fresh & Rotten, Strangers only.
5. Priorities: Your Haulers fill the 1x1 zone. Your Crafter burns from that zone instantly.
6. If the 1x1 zone overflows, haulers move bodies into the stone room. Once a month, toss a Molotov in the stone room to reset it entirely.
7. Never allow colonist corpses in any of these zones. Build a dedicated sarcophagus room for them.

"Should I cremate mechanoids?"

No. Mechanoids (dead) cannot be cremated via the Crematorium bill unless you mod the game. They must be:

• Smelted at the Electric Smelter (for steel/plasteel).
• Shredded at the Machining Table (for components).
• Or burned in a Molotov room.

Never put a mech in your corpse freezer. RimWorld: How to Cremate Corpses Best – The

3. Electric Crematorium (Standard Mid-Late Game)

• How: Research Electric Crematorium → build (requires 145 steel, 8 components) → set bill for “Cremate corpse” (allow human/animal corpses).
• Speed: ~1 corpse per 2 hours (depends on colonist’s Manipulation).
• Pros: Automated via Work tab (Hauling + Cremation priority); produces no filth.
• Cons: High power draw (350W); requires research; components costly early on.

Method 2: The Molotov/Fire Bow (Best for Early Game)

You don't have electricity or components on day 1. How do you deal with the three raiders you just killed?

The Fire Method.

Conclusion

The best way to cremate corpses in RimWorld depends on your tech level. Early game: Molotov in a stone shack. Late game: Electric Crematorium with a 1x1 haul buffer.

Never bury raiders. Never leave them in the river. Turn off the "Observed Corpse" spam forever. Keep your pawns happy, your base clean, and your framerate high. Build a stone room with a stone door next to your killbox

Now go burn those tribals. The storyteller will send more tomorrow.

Requirements:

• A pawn with Molotov Cocktails, Incendiary Launcher, or an Incendiary bow (tribal start).
• A Stone room (wooden walls will burn the colony down).

The "Best" Way to Run It

The biggest mistake players make is letting their Doctors or Crafters waste time cremating.

1. Open the Schedule Tab.
2. Assign a "Janitor": Designate one colonist (preferably one with high physical labor but low intellectual/social skills) to handle corpse burning. Restrict their work tabs to only "Hauling" and "Cooking" (which covers cremating).
3. Night Shift: Corpses generate horror thoughts. Have your cremator work at night while the rest of the colony sleeps, keeping them away from the gruesome sight during the day.
