Rust Tower Base Design (2026)

Tower Base build cost

The reference build we cost is a 2x2 footprint, four storeys, sheet metal throughout — 52 building blocks plus doors and a tool cupboard. Every rate below is what the game charges for that piece: the twig it is placed as, then the upgrade. A floor or roof costs half a wall, a doorway or window 70%.

Tower Base upkeep

Rust bills upkeep by building-block count: 10% of build cost per day for the first 15 blocks, 15% for the next 50, 20% for the next 125 and 33.3% after that. At 52 blocks this design pays a blended 13.6% a day, doors included; the tool cupboard itself costs nothing to keep.

Over a full seven-day wipe cycle that is 8,694 metal frags — the number worth checking before you commit to a size. Work out how long your TC lasts.

What it costs to raid

Cost of the cheapest route from outside to the loot room, searched by the base planner on the exact piece list above — doors included, because a door on the outside is what a raider actually breaks.

That is 2,800 sulfur in rockets, or 2,200 sulfur in C4. The cheapest method that can break the whole path is 63× explosive 5.56 ammo at 1,575 sulfur. Compare every explosive.
