Upgrade Benches first debuted back in Fortnite Chapter 2 Season 1, and as you can expect, interacting with it lets you upgrade your weapons, increasing its Rarity up one level and improving its stats; Damage, Fire Rate, Magazine Size, Reload Time, or what have you. Aside from upgrading your weapons just for the sake of buffing them, sometimes Quests task you with upgrading them as well. Here is the list of all Upgrade Bench locations that you can find in the Fortnite Chapter 3 Season 4 battle royale island.

Fortnite Chapter 3 Season 4 –  All 18 Upgrade Bench Locations

  • Logjam Junction: North of it, in Washout Wharf
  • Logjam Junction: West of it, near a house with a green roof
  • Logjam Junction: West of it, in an unmarked gas station
  • Chonker’s Speedway (1)
  • Chonker’s Speedway (2)
  • Sleepy Sound: Southwest of the area
  • Rave Cave: West of the area, in an unmarked gas station
  • Fort Jonesy: Head east, in an unmarked gas station
  • Shimmering Shrine: Go northwest, in an unmarked gas station
  • Shroom Station: From the Reality Tree, head southeast
  • Cloudy Condos: North of the area
  • Lustrous Lagoon: Head east from the area
  • Tilted Towers: Go south from the area
  • Greasy Grove
  • Rocky Reels
  • Synapse Station
  • Launchpad
  • Coney Crossroads

When you found an Upgrade Bench in Fortnite Chapter 3 Season 4, you can use upgrade a weapon from and up to:

  • Common/Grey: Base
  • Uncommon/Green: 50 Gold Bars
  • Rare/Blue: 150 Gold Bars
  • Epic/Purple: 250 Gold Bars
  • Legendary/Orange: 350 Bars
  • Exotic: Cannot upgrade to Exotic

However, keep in mind that finding weapons laying about in Vaults or buying Exotics from NPCs are also viable options to acquire rarer weapons, so you might want to hold your Gold Bars for something else instead. Especially since Epic Games has reworked the loot system starting from Fortnite Chapter 3, finding good guns is no longer a matter of pure luck.

Fortnite is available for PC, PS4, PS5, Xbox One, Xbox Series X|S, Nintendo Switch, iOS, and Android.
