Rust Bunker Guide: Every Bunker Type, Tier List & How to Build (2026)

A Rust bunker is a sealed part of your base that only you can open. Raiders who get through your walls still find the tool cupboard or the loot room closed off, with no door to blow, so they have to pay for at least one more wall or give up. Bunkers are the cheapest raid cost you can add to a base, and almost every good 2026 base design uses at least one.

This guide covers every Rust bunker type that still works on the October 2026 Livestock patch: how each one is built, how you open and close it, what it costs and how raiders beat it. You also get the bunker tier list from S to F, the bunkers that were patched, the best bunker for solos, duos and clans, the build costs and raid costs, and the 2025 and 2026 tutorials worth copying. For full bases built around these tricks, see our Rust base designs, and for the building basics start with the Rust building guide.

What Is a Bunker in Rust?

A bunker is a section of your base with no way in except through a building piece that only you can remove or place. You seal your tool cupboard, your loot boxes or your external TCs inside it, and you open it again with a twig piece, a roof or a rotated vending machine. Because placing and rotating pieces needs building privilege, a raider who is not authed on your TC can’t use the same trick. Their only options are to blow through more walls or break the piece from the soft side.

That is why bunkers matter so much for offline raids. A normal 2×2 lets raiders blow one wall and one door to reach the TC. A bunkered 2×2 makes them blow that wall, then another armored or sheet metal wall around the bunker, and many groups don’t carry enough explosives for the second one. The bunker also hides where your loot is, so raiders waste rockets guessing.

Bunkers have downsides too. They take space, some are fiddly to build, and if a raider breaks the sealing piece from the outside and you have no bag inside, you can be locked out of your own base. Every bunker also needs upkeep on its extra pieces, so check the upkeep calculator before you add five of them.

How Bunkers Work: The 4 Mechanics

Every bunker in Rust is built on one or more of four building rules. Once you understand them, you can read any bunker tutorial and know why each step is there.

Rust Bunker Tier List (2026)

The tiers follow the bunker tier list from Rust builder Crow, which RustBaseDesign keeps up to date (last updated June 2026), checked against 2025 and 2026 tutorials. A bunker gets a high rank for being cheap, simple, hard to soft side and easy to fit into any base.

Vending Machine TC Bunker (S Tier)

The Vending Machine TC Bunker is the most used bunker in Rust and the best one to learn first. A vending machine sits in the doorway in front of your tool cupboard (or lockers, boxes or a large battery). It fills the gap so nobody can walk or reach past it. If you are authed on the TC, you can rotate the vending machine out of the way, grab what you need and rotate it back. A raider who isn’t authed can’t rotate it, so they have to break it or blow the walls around it.

The vending machine crafts at a Workbench 1 for 20 high quality metal and 3 gears and is a default blueprint, so you can bunker your TC on day one. Since the Meta Madness update (May 2024) it rotates 90 degrees, which is what makes the bunker easy to open. The machine itself has 1,250 HP, so breaking it costs 3 C4 or 10 rockets, and most raiders go through the walls beside it instead.

How to build the Vending Machine TC Bunker

1. Build the room the TC goes in with a single doorway, and upgrade the doorway to stone, sheet metal or armored.
2. Place the TC a little past the doorway, in the middle of the room. Keep it close to the door and to the right so splash from a side rocket can’t reach it.
3. Rotate the vending machine and place it in the doorway, as close to the doorway as it will go.
4. Optional: hang a door on the inside for extra raid cost. Crow’s numbers put an armored vending bunker at about 15 rockets.
5. To open it, auth on the TC and rotate the vending machine. Rotate it back before you log off.

The loot room version works the same way. Add two or three triangle foundations off one side of the sealed base, wall them in, place shelves and up to four boxes, then put an upgraded doorway and the vending machine in front. Leave a little room between the machine and the doorway or you won’t reach the boxes.

Roof Bunkers: Vending Roof, Freehand and Multi TC

Roof bunkers use the roof split rule. You build a wall that is attached on only one side, and when you place a roof or triangle roof next to it, the wall opens. Remove the roof and it is sealed again. Placing a roof needs building privilege, so a raider can’t do it.

Vending Roof (shop) Bunker (S tier)

Place a wall, then place a vending machine right against it, usually on your roof as a drone shop. The back of the vending machine can only be reached once a thatch or twig triangle roof splits the wall. Upgrade the wall to armored so it can’t be soft sided. Never attach anything to every side of that wall, or it can never be opened again. An armored wall takes about 15 rockets or 8 C4.

Freehand Bunker (S tier, best for external TCs)

A square foundation is placed freehand, slightly lower than the triangles next to it, so its wall is attached on one side only. The wall’s stability must read 78 to 79 percent or you redo it. Upgrade it, cover the gaps with a triangle frame from above, and put the external TC on a metal triangle behind it. Open it by placing a triangle roof on the left side, and close it by destroying the roof. You can also disconnect the external from the main base with a square roof and reconnect it with frames. It is tricky to build, so keep a spare foundation and frame nearby so you can rebuild it if someone soft sides the foundation.

Multi TC Bunker (A tier, best for loot rooms)

A sealed loot room high in the base that belongs to an external TC instead of the main one. Build seven or eight squares out from the base with a triangle at the end, demolish the squares and build back with triangles only, then remove every triangle except the two touching the base. Build it on the second or third floor, wall it in, and seal it with a regular wall. Cover the gaps with a wall frame or door frame of the same material as the outer wall, facing the same way. It holds about four large boxes and a battery, and you open it with a twig roof, which costs nothing.

Stability, Stair and Roof Foundation Bunkers

Stability (raised foundation) Bunker (C tier)

The oldest bunker in Rust, and one that still works on PC and console. On a 3×1, place three triangle foundations, two of them raised. Build half walls on the two walls touching the bunker area and delete the bottom one; the top one stays up thanks to stability. Place the lower half wall and keep it twig, then seal the entrance with a triangle floor upgraded to metal or armored. To open it, break the twig half wall and the triangle drops. To close it, place a new half wall inside and cover it with a ceiling. It is bulky, and if more than one person uses it the last one out has to seal it.

Stair Bunker (C tier)

Stairs over the drop into the core, held up by a twig or wood triangle. Break the triangle and the staircase falls. Use wood instead of twig when you are offline, put a window above it to stop molotovs, and use it to block the first to second floor doorway rather than the ground floor opening, where twig can be splashed from below. It is “more of a blocker than a bunker”, but it is cheap and quick.

Roof Foundation Bunker (B tier)

A core entrance bunker. A roof is held up by a single raised foundation next to a square drop down into the core. Upgrade that foundation to wood, not twig: twig pokes through the sides and can be shot from outside, while wood can only be broken from inside with a couple of machete hits. Destroy the foundation and the roof collapses. Every re-seal costs about 13 high quality metal for the roof, and it needs a big footprint.

Terrain Bunker (B tier)

The twig foundation that seals the entrance sits under the terrain, so raiders can’t shoot it from outside. It has no soft side and is cheap, but you need exactly the right spot and must plan the base around it, so it suits small starter bases.

Other Bunkers That Still Work

Ladder hatch bunkers got a lot better in 2026. The Spring Clean update (April 2026) added the armored ladder hatch and made square ladder hatches flush with the floor, so builders now hide floating stability bunkers and floor stacked loot rooms under them. Floor stacking itself still works in October 2026, and the newest method uses a low wall, a ramp, a roof and two small boxes as a guide.

Patched Bunkers: What No Longer Works

At the April 2024 force wipe, every bunker that used a pixel gap between floors and foundations stopped working on PC: the offset bunker, the God bunker, the Roden bunker and the classic pixel gap bunker. Facepunch never named the change in its patch notes, but builders confirmed they became impossible to build. They still work on Rust Console Edition, which runs an older building system.

Some builders showed new pixel gap methods in 2025 and 2026, but they are fiddly, they break easily, and Facepunch can close them at any monthly update. Don’t build a base that depends on one. The old twig-above-the-roof bunker is also out: Facepunch stopped roof bunkers being opened from outside in 2020, and an incendiary rocket or molotov at the right spot burns the twig anyway.

Best Bunker for Solo, Duo and Clan

If you are a solo, don’t try to bunker everything. One vending bunker on the TC and a stair bunker on the core is plenty, and every extra bunker adds upkeep. Bigger groups get more value from bunkers, because raiders must find them all. Base designs like Limi Lab’s Aether (7 bunkers) or Nini Rust’s The Ghost (6 bunkers) spread the loot across many sealed rooms so no single raid path gets everything. Remember that since Breach and Clear (September 2026), TC upkeep goes up for groups bigger than four, so every bunker pod costs a clan more to keep than it costs a duo.

Bunker Cost and Raid Cost

A bunker itself costs very little: a vending machine, a twig roof or a twig half wall. The real cost is the extra high tier walls around it. Here is a reference sheet metal 2×2 bunker base, two storeys with a sealed bunker below (36 building blocks), costed for the Livestock patch:

Upkeep on that base is about 876 metal fragments a day, or 6,132 for a week. To raid it, a group needs 7 rockets or 4 C4 through the doors, or about 276 explosive 5.56 rounds. Use the Rust raid calculator and the raid chart to price your own layout.

Common Bunker Mistakes

• No bag inside. If a raider breaks your sealing piece from outside and you can’t open it, a sleeping bag inside is the only way back in.
• Attaching to the opening wall. Roof bunkers only open while the wall is attached on one side. One extra ceiling or wall and it is sealed for good.
• Leaving the twig exposed. Twig and wood supports must be inside the base, away from outer walls, or rocket splash and molotovs break them for the raider.
• Building a patched bunker. Old pixel gap and offset tutorials from before 2024 won’t seal on PC.
• Forgetting upkeep. Every bunker adds pieces to the TC. Watch your decay and upkeep or the base falls on its own.
• Not sealing when you leave. A bunker you leave open is just a room.

Bunkers are only worth it if your base lasts the wipe. Check when the next force wipe lands on our Rust force wipe countdown before you sink 50,000 stone into a bunkered main.
