Finding the Chest in Luigi s Mansion 3 Laundry Room: A Guide to Discovering Hidden Treasures

In Luigi’s Mansion 3, the Laundry Room can be found on the Basement 1 (B1) level of the hotel. Players often search for the hidden chest in this room as part of their ghost-hunting and treasure-collecting adventure. To find the chest in the Laundry Room, enter through the Maintenance Room or the garage, and move toward the left section where you’ll see washing machines lining the wall. Use the Poltergust G-00 to interact with the machines: some might yield coins or bills, but to reveal the hidden chest, focus on the machine that's vibrating or sparkling. Open it or smash it with a suction shot. Alternatively, shining your Dark-Light Device on suspicious areas will reveal invisible objects or open new paths. After triggering the mechanism, the chest appears and you can open it for your reward—usually a collection of cash and, occasionally, a gem.

Tips 1:

As an interior designer, I always approach these puzzles like a room layout challenge—look for clues in the room’s spatial arrangement and interactive elements. If you want to practice rearranging or designing rooms virtually, tools like a room planner can help you sharpen your layout intuition and make problem solving more intuitive in both games and real-life spaces.
