Tool Cupboard Rust: Upkeep, Decay & Building Privilege

Updated August 2026

Tool cupboard Rust protection is the foundation of every secure base. You can build the prettiest bunker on the server, wall it in armored, hang a sheet metal door on every frame, and still lose the whole thing in a day. Not to C4. To a little wooden box you forgot to fill.

The tool cupboard Rust players depend on is the single most important deployable in the game, and it is the one new players understand the least. It decides who is allowed to build on your land, it quietly pays the rent that stops your walls rotting, and if a raider gets their hands on it, they own your base without spending a rocket.

This tool cupboard Rust guide covers everything: what a TC actually does, the 50 metre building privilege bubble, how upkeep and decay really work, whether you can pick one up and move it, the cheapest ways to break an enemy one (one molotov, usually), skins, and the griefing trick that ends more bases than sulfur ever will. Every number here is checked against the in game data, not guessed.

The Rust tool cupboard, the deployable that sets building privilege and pays upkeep, shown with its core stats of 100 HP, 1000 wood, 50 metre radius and 24 slots — The tool cupboard. One hundred health, a thousand wood, and the only thing standing between your loot and the void.

TL;DR A tool cupboard Rust players call a TC is a deployable that sets building privilege in a 50 metre radius. Only players authorised on it can build, upgrade, rotate or pick up structures in that area. It costs 1,000 wood, needs no workbench, has 100 HP and 24 slots that hold your upkeep resources. Keep it stocked or your base decays, tier by tier: twig in about an hour, stone in five, sheet metal in eight, armored in twelve. You cannot pick a placed TC back up, so put it somewhere you cannot reach it. Because it only has 100 HP, the cheapest way to break an enemy one is fire: one to two molotovs, which cost zero sulfur.

Tool cupboard Rust guide: what is a TC?

TC is short for tool cupboard. This essential tool cupboard Rust deployable goes inside your base, and it does two jobs that nothing else in the game does.

First, it sets building privilege. The moment you place a cupboard and authorise yourself on it, you claim a sphere of ground around it. Inside that sphere, only authorised players can build new structures, upgrade walls from wood to stone, rotate a wall, or pick up placed deployables. Everyone else gets the dreaded “Building is blocked” message. That is how you stop a stranger from door camping your loot room by slapping their own wall down inside your house.

Second, it holds your upkeep. Rust bases do not last forever on their own. Every structure slowly decays, and the cupboard pays a daily resource cost out of its own inventory to keep everything at full health. Empty cupboard, no upkeep, dead base.

So when a Rust player says “protect the TC” or “go for their TC”, they mean the cupboard. It is the beating heart of the base. Take it and the base is yours. Lose it and the base is nobody’s.

What does TC mean in Rust? TC just stands for tool cupboard. You will also hear “cupboard”, “cuppy”, or “the priv” (short for building privilege). They all mean the same wooden box. There is only ever meant to be one per base, and it should be the hardest thing in your entire build to reach.

What is building privilege in Rust?

Building privilege is the invisible claim a cupboard puts on the ground. Place a TC, authorise on it, and you own a 50 metre radius of build rights. It works both ways, and understanding both sides is what separates a base that holds from a base that gets grubbed on day one.

Rust building privilege diagram: the tool cupboard projects a 50 metre radius where only authorised players can build, while everyone else is building blocked — Inside the bubble, authorised players build freely and everyone else is locked out.

For you and your team: anyone authorised on the cupboard can place walls and floors, upgrade them, rotate them, and pick up deployables inside the radius. If a friend wants to help build, they walk up to the same TC and authorise too. No auth, no building, even for a teammate.

For everyone else: a player who is not authorised cannot build inside your privilege at all. They cannot even place their own tool cupboard within range of yours. That is why you sometimes try to build a base near a monument or another player and get “Building is blocked”. Somebody else’s cupboard is claiming that ground.

You cannot build near an enemy TC This cuts both ways when you raid. If you break into a base but leave the enemy cupboard standing, you still cannot build, upgrade or place anything inside it, which means no ramps, no shooting floors, and no sealing yourself in with loot. Destroying or authorising on the cupboard is step one of taking a base, not an afterthought.

How to place and authorise a tool cupboard Rust base

How to place and authorise a Rust tool cupboard in four steps: craft it with 1000 wood, hold E, choose authorise, then load it with upkeep materials — Four steps from a bag of wood to a base only you can touch.

Craft and place it. The cupboard costs 1,000 wood and needs no workbench, so you can make one in the first minutes of a wipe. Place it deep inside your base, ideally walled off in its own compartment.
Hold E on the cupboard. The radial menu opens with options including Authorize Me, Clear List and Show Building Privilege.
Choose Authorize. You are now on the authorised list. From this moment only you (and anyone else who authorises) can build, upgrade and pick up inside the 50 metre radius.
Load it with upkeep materials. Open the cupboard like a box and drop wood, stone, metal fragments and HQM into its 24 slots. This is the fuel that keeps the base standing while you are offline.

Clear the list before you log off a shared base If you play with randoms, remember that anyone authorised can pick your whole base apart from the inside. Use Clear List to wipe every name (including your own, so re-authorise after), and only let people you trust stay on the cupboard. A teammate who goes rogue with authorisation is worse than a raider.

Tool cupboard Rust upkeep: feeding your base

Upkeep is the daily resource cost the cupboard pays to stop your structures decaying. Think of it as rent. You stock the cupboard, and every day the game deducts a portion to keep every wall, floor and door at full health.

Rust tool cupboard upkeep: it consumes wood, stone, metal fragments and high quality metal each day, and the cost scales with how much you have built — The cupboard eats whichever materials your base is built from, and the bill grows as your base does.

Two things decide your daily bill:

What your base is made of. The cupboard consumes the same materials you built with. A stone base burns stone, a sheet metal base burns metal fragments, an armored base burns high quality metal. Keep the right material stocked or that tier will not get paid.
How big your base is. Upkeep scales with the number of building blocks in your privilege. A 2×2 costs almost nothing. A giant clan compound costs a mountain of resources every day, because the per block cost climbs the more you build. This is Facepunch’s deliberate brake on endless megabases.

As a feel for it, a single stone wall costs up to around 99 stone a day at the top bracket, while a sheet metal wall costs somewhere between 20 and 66 metal fragments a day. Upgrading from stone to sheet metal actually lowers your fragment upkeep relative to health, which is one reason metal is the sweet spot for most bases.

Twig is free, and that is a trap Twig costs no upkeep, so leaving twig spam around your base feels clever. It is not. Twig also decays fastest and can be broken by hand, so anything important sitting behind twig is barely protected. Build for real, then pay for it.

Rust decay: what happens when the cupboard runs dry

If your cupboard runs out of upkeep materials, decay begins. Decay chews health off your structures over time until they collapse. Different tiers rot at very different speeds, which is exactly why people ask how long a stone wall or a sheet metal wall lasts.

Rust decay timer chart: twig lasts 1 hour, wood 3 hours, stone 5 hours, sheet metal 8 hours and armored 12 hours once tool cupboard upkeep stops — How long a full health building block survives once the upkeep stops.

Building tier	Time to decay from full	Notes
Twig	~1 hour	Barely there, breaks by hand anyway
Wood	~3 hours	Also takes full fire damage
Stone	~5 hours	The most common base tier
Sheet Metal	~8 hours	Immune to fire, the value pick
Armored	~12 hours	Longest grace, highest upkeep

Those are the times for a single full health block to fall on its own after upkeep stops. A stacked, honeycombed base takes far longer to fully collapse because the outer layers rot first and buy the core more time. But the clock only starts when the cupboard is empty, so the real lesson is simple: never let it hit zero.

The cupboard itself decays after 48 hours Even the TC is not immune. If you place a cupboard and never feed it, it starts to decay after about 48 hours and eventually breaks, taking your building privilege with it. This is how abandoned bases eventually open up on a wipe, and it is why offline decay matters as much as any raid.

Rust upkeep and decay calculator: how to estimate your costs

There is no need to guess your daily bill, because the cupboard tells you. You do not need a separate Rust decay calculator or upkeep calculator to run a normal base. The information is baked into the game.

Hold E on the cupboard and read the panel. The tool cupboard UI shows the current daily upkeep cost for each material, and how long your stocked resources will last at that rate. That is your live decay timer.
Hit it with a hammer to see privilege info. A hammer swing on the cupboard, or the Show Building Privilege option, highlights the blocks it is paying for and confirms you are authorised.
Do the quick maths. Upkeep is charged per building block as a fraction of that block’s build cost, and the fraction climbs the more blocks you have. Roughly, a small solo base runs on a few hundred resources a day, while a large clan compound can burn thousands.

If you want a hard number before you build, community decay and upkeep calculators let you enter your wall count and tier to estimate the daily draw. They are useful for planning a big base, but for day to day play the in game cupboard panel is the only calculator you actually need. Stock it above your daily cost, check it each time you log in, and decay never touches you.

The one number to remember Keep at least three days of upkeep in the cupboard at all times. That covers a normal weekend away and sits comfortably inside every tier’s decay window, so even if real life pulls you offline, the base is still standing when you get back.

Can you pick up or move a tool cupboard Rust deployable?

This is one of the most common questions, and the answer surprises people: no, you cannot pick up a placed tool cupboard. There is no hammer pickup for it the way there is for a box or a furnace. Once it is down, it is down.

You cannot pick up a placed tool cupboard in Rust; to move it you have to destroy the old one and place a new one — No pickup on a placed TC. Moving it means destroying it and crafting another.

To move a tool cupboard, you destroy the old one and place a fresh one where you actually want it. A new cupboard is only 1,000 wood, so the cost is trivial. The annoying part is that destroying it clears its authorised list and resets your privilege, so do it when the base is safe, not mid raid.

Plan the spot before you commit Because you cannot move it later without breaking it, think about placement on the first day. The ideal cupboard sits in a sealed one by one core, surrounded by honeycomb, with no line of sight and no soft wall next to it. If a raider has to blow through your entire base just to reach the box, you have done it right.

How to break a tool cupboard Rust TC

When you raid, destroying the enemy cupboard is what unlocks the base for you, and it is shockingly cheap because a TC only has 100 HP. The catch is that it resists melee hard, so the smart tools are fire and small explosives, not your hatchet.

How to break a tool cupboard in Rust: 1 to 2 molotovs, 2 incendiary shells, 4 beancans, 1 satchel, 1 incendiary rocket or 9 explosive 5.56 rounds — The cheapest ways to break a 100 HP tool cupboard. Fire wins.

Method	Amount	Sulfur cost	Notes
Molotov Cocktail	1 to 2	0 sulfur	Fire ignores its armor, cheapest option
12 Gauge Incendiary Shell	2 shells	40 sulfur	Eoka or any shotgun, dirt cheap
Incendiary Rocket	1 rocket	300 sulfur	Instant, if you have a launcher
Beancan Grenade	4	480 sulfur	Watch for duds
Satchel Charge	1	480 sulfur	One does it, but can misfire
Explosive 5.56 Ammo	9 to 10	~225 sulfur	Any assault rifle, very reliable
Rocket	1	1,400 sulfur	Massive overkill
Timed Explosive (C4)	1	2,200 sulfur	Never do this to a bare TC

How many molotovs for a TC? One molotov does around 147 fire damage over its burn, which is more than the cupboard’s 100 HP, so a clean throw kills it. In practice, bring two in case the first does not fully ignite the box. At zero sulfur, this is the cheapest raid tool in the game.

How many spears to break a TC? If you insist on melee, expect to wear out roughly 48 wooden spears or 52 stone spears. The cupboard has heavy melee resistance, so each hit chips only a sliver and your spears break long before it does. Salvaged axes are the “best” melee at about four axes destroyed, but honestly, throw a molotov.

Break the TC, then the loot room Raiders new to the game blow the loot room first and wonder why they still cannot build a ramp inside. Kill the cupboard early. With no privilege in the way, you can place your own honeycomb, seal the base, and take your time. A dead TC is the difference between a raid and a robbery.

Tool cupboard Rust skins

Rust tool cupboard skins are cosmetic only and do not change the 100 HP health, the upkeep cost or the building privilege radius — Skins repaint the box. They never change the health, upkeep or privilege.

Yes, the tool cupboard has skins, and they are purely cosmetic. A skin swaps the wooden cabinet for something like the store’s Retro Tool Cupboard or a workshop design, but it does not touch the 100 HP, the 50 metre radius, or the upkeep cost. Nobody can tell how tanky your TC is from its paint job, because the stats are identical across every skin.

You apply a skin through a repair bench or on craft, the same as any other deployable. It is a nice touch for a base tour, but it changes nothing that matters mechanically. Do not pay for a skin thinking it protects your base better. It does not.

TC griefing: the trick that ends bases

Because a cupboard controls who can build, players weaponise it. TC griefing is when someone uses building privilege to ruin your base rather than loot it.

The classic version: a raider breaks in, and instead of just taking your loot, they place their own tool cupboard inside your base and authorise on it. Now their privilege overlaps yours. You come back online and find you cannot repair your walls, cannot upgrade, and cannot pick up your own deployables, because an enemy cupboard is claiming the ground. Your base is intact and completely unusable.

Another version happens before a raid even starts: an enemy builds twig right up against your walls, using their privilege to deny you the space to expand or add external defences.

How to stop TC griefing Honeycomb every external wall so there is no open floor space inside your base for an enemy cupboard to land on. Leave no gaps a raider can stand a TC in. And if you do get griefed, the fix is to find and destroy the enemy cupboard, which frees your privilege again. Deploying your own external TCs around the base also blocks enemies from claiming the ground next to you.

Tool cupboard Rust pro tips

One cupboard, buried deep. Never place the TC on an outer wall or anywhere with a soft side facing out. It should be the last thing a raider reaches, not the first.
Overstock before you log off. Fill all 24 slots before a long break. Upkeep only pulls what it needs, and a full cupboard can carry a small base through several offline days.
How many turrets per TC? There is no cap tied to the cupboard itself. The real limit is turret interference: only 12 powered auto turrets work within a 40 metre bubble, so space them out.
Check upkeep with the hammer. Hold E on the cupboard and pick Show Building Privilege, or hit it with a hammer, to see the daily cost and how long your current stock lasts.
Do not store loot in the TC. It is not a box for your guns. Keep it for upkeep materials only, so a raider who cracks it gets wood, not your kits.

Your upkeep clock resets on force wipe. When the map wipes, every base, every cupboard and every scrap of upkeep is gone, so know the date before you overstock for the week.

Tool cupboard Rust FAQ

What does TC mean in Rust?

TC stands for tool cupboard. It is the wooden deployable that sets building privilege and pays upkeep for your base. Players also call it the cupboard, the cuppy or the priv.

What does a tool cupboard do in Rust?

It does two things. It sets building privilege in a 50 metre radius, so only authorised players can build, upgrade or pick up structures there. And it pays upkeep from the materials stored inside it, which stops your base from decaying.

How much does a tool cupboard cost in Rust?

1,000 wood. It needs no workbench and is known by default, so you can craft one within the first few minutes of a wipe. It takes 7 to 30 seconds to craft depending on whether you use a workbench.

How much health does a tool cupboard have?

100 HP. That is very low, but the cupboard has heavy melee resistance, so tools like spears and hatchets are extremely inefficient against it. Fire and small explosives are the fast way through.

Can you pick up a tool cupboard in Rust?

No. A placed tool cupboard cannot be picked back up. To move it you have to destroy the old one and place a fresh one, which only costs 1,000 wood but resets its authorised list.

How do you move a tool cupboard in Rust?

You cannot move it directly. Break the existing cupboard, then craft and place a new one in the spot you want. Because there is no pickup, it is worth planning the placement carefully before you commit on wipe day.

How many molotovs does it take to break a tool cupboard?

One molotov does around 147 fire damage over its burn, which is enough to destroy a 100 HP cupboard on a clean throw. Bring two to be safe in case the first does not fully ignite it. Molotovs cost zero sulfur, making them the cheapest option.

How many spears does it take to break a tool cupboard?

Around 48 wooden spears or 52 stone spears, because the cupboard has heavy melee resistance and your spears wear out from durability before it dies. Melee is a poor choice. A single molotov or two incendiary shells is far cheaper.

What is building privilege in Rust?

Building privilege is the 50 metre claim a tool cupboard puts on the ground. Only players authorised on the cupboard can build, upgrade, rotate or pick up structures inside it. Everyone else sees Building is blocked and cannot place anything, including their own TC.

How long does it take for a base to decay in Rust?

Once upkeep runs out, a full health block decays in about 1 hour for twig, 3 hours for wood, 5 hours for stone, 8 hours for sheet metal and 12 hours for armored. Honeycombed bases last longer overall because the outer layers rot first.

What happens if the tool cupboard runs out of upkeep?

Your base starts to decay, losing health tier by tier until structures collapse. The cupboard itself also decays after about 48 hours if left empty, which removes your building privilege entirely. Keep it stocked and the clock never starts.

Can you have more than one tool cupboard in a base?

You are only meant to run one main cupboard per base, since privilege bubbles conflict. Players do place extra external cupboards around a base to deny nearby ground to enemies, but your core base should be paid for by a single, deeply protected TC.

Do tool cupboard skins change the stats?

No. Skins such as the Retro Tool Cupboard are cosmetic only. They do not change the 100 HP health, the upkeep cost or the 50 metre building privilege radius. Every skinned cupboard behaves identically.

What is TC griefing in Rust?

TC griefing is when an enemy uses building privilege to disable your base instead of looting it, usually by placing their own tool cupboard inside your walls after a raid so you cannot repair, upgrade or pick anything up. The fix is to find and destroy their cupboard, and to honeycomb your base so there is no space to plant one.
