OSRS POH Costume Room: Your Ultimate Guide to Storage and Style

OSRS POH Costume Room: Your Ultimate Guide to Storage and Style


The Old School RuneScape (OSRS) Player-Owned House (POH) is a fantastic feature that lets players flex their creativity and utility through the Construction skill. Among its many rooms, the Costume Room stands out as a must-have for anyone looking to save bank space while keeping their wardrobe organized. Whether you’re a seasoned adventurer hoarding Treasure Trail rewards or a casual player collecting holiday items, this guide will walk you through everything you need to know about the OSRS POH Costume Room. Let’s dive into how it works, what you can store, and why it’s a game-changer for your RuneScape experience.

The Costume Room is a specialized area within your Player-Owned House, designed to store a variety of items that would otherwise clutter your bank. Introduced as part of the Construction skill, it’s a low-competition feature that many players overlook, yet it offers incredible utility. From capes to armor sets, this room is your one-stop shop for managing cosmetic and functional gear.

Unlocking the Costume Room

To build a Costume Room, you’ll need at least 42 Construction. It costs 50,000 coins to construct, making it an affordable addition compared to other high-end POH rooms. Once built, you can place it anywhere in your house layout, though many players tuck it away upstairs or in a corner for efficiency.

Why It’s a Bank Space Savior

With a bank limit of 800 slots (as of April 2025), every item counts. The Costume Room lets you store hundreds of items—think random event gear, holiday rewards, and more—without taking up precious bank space. It’s especially clutch for Ultimate Ironmen who rely on alternative storage solutions.

Types of Storage in the Costume Room

The Costume Room isn’t just a single piece of furniture—it’s a collection of storage units, each with its own purpose. Here’s a breakdown of what you can build and what they hold.

Treasure Chest

The Treasure Chest is your go-to for storing Treasure Trail rewards. From pirate hats to elegant dresses, it keeps your clue scroll loot safe and accessible.

  • Basic Treasure Chest (Level 48): Stores easy clue rewards.
  • Fancy Treasure Chest (Level 54): Adds medium clue rewards.
  • Mahogany Treasure Chest (Level 66): Holds all clue rewards, including hard, elite, and master tiers.

Armour Case

Perfect for armor sets, the Armour Case consolidates bulky gear into one neat package.

  • Oak Armour Case (Level 46): Stores 2 sets.
  • Teak Armour Case (Level 64): Stores 4 sets.
  • Mahogany Armour Case (Level 82): Stores all available sets.

Cape Rack

For cape collectors, the Cape Rack is a dream. It stores everything from skill capes to milestone capes.

  • Oak Cape Rack (Level 54): Holds basic capes.
  • Teak Cape Rack (Level 63): Adds more variety.
  • Mahogany Cape Rack (Level 72): Stores all capes except Capes of Accomplishment.
  • Marble Cape Rack (Level 80): Stores everything, including untrimmed skill capes.

Other Storage Options

Beyond the big three, you’ve got:

  • Fancy Dress Box: For random event costumes (Level 44+).
  • Toy Box: For holiday items like Easter eggs or Christmas crackers (Level 50+).
  • Wardrobe: For cosmetic outfits like the Lumberjack set (Level 44+).
Furniture Construction Level Storage Capacity
Mahogany Treasure Chest 66 All clue rewards
Mahogany Armour Case 82 All armor sets
Marble Cape Rack 80 All capes

How to Build and Upgrade Your Costume Room

Building and upgrading your Costume Room is straightforward, thanks to the flat-pack furniture system. Here’s how to get started.

Materials You’ll Need

Most furniture requires planks and nails, with higher tiers demanding better materials:

  • Oak Items: Oak planks (e.g., 2 for an Oak Armour Case).
  • Teak Items: Teak planks (e.g., 4 for a Teak Cape Rack).
  • Mahogany Items: Mahogany planks (e.g., 3 for a Mahogany Treasure Chest).
  • Marble Items: Marble blocks (e.g., 1 for a Marble Cape Rack).

Flat-Pack Furniture Advantage

One of the best perks? All Costume Room furniture can be made as flat-packs at a workbench. This means you can craft them ahead of time, trade them, or even sell them on the Grand Exchange. No need to lug materials into your POH every time you want an upgrade.

Step-by-Step Building Guide

  1. Reach the required Construction level for your desired furniture.
  2. Gather materials (planks, nails, or marble blocks).
  3. Enter building mode in your POH.
  4. Right-click a hotspot in the Costume Room and select “Build.”
  5. Choose your furniture and confirm the construction.

Maximizing Your Costume Room’s Potential

The Costume Room isn’t just about storage—it’s about efficiency and style. Here’s how to make the most of it.

Optimal Placement in Your POH

While you can place the Costume Room anywhere, consider accessibility. Many players pair it near the entrance portal or upstairs with less-used rooms like bedrooms. For Ultimate Ironmen, keeping it close to a bank (via house teleport) is key since you’ll access it remotely.

Combining with Other Rooms

Pair your Costume Room with a Workshop to craft flat-packs on-site, or a Menagerie to store pets, freeing up even more bank space. A nearby Portal Chamber can also make your house a teleport hub, enhancing its utility.

Styling Your Costume Room

Want to flex? Use a high-level house style (like the Zenevivia Dark Stone) to give your Costume Room a sleek, thematic vibe. It won’t affect storage, but it’ll impress visitors during house parties.

Why Every OSRS Player Needs a Costume Room

Still on the fence? Here’s why the Costume Room deserves a spot in your POH.

Bank Space Management

With over 200 storable items (and growing as Jagex adds more cosmetics), the Costume Room is a lifeline for packrats. Imagine stashing every holiday item from the past decade without losing a single bank slot.

Ultimate Ironman Benefits

For UIM players, the Costume Room is a godsend. Since you can’t use banks, this room—accessible via house teleports—becomes your primary storage for non-essential gear. The 2020 Costume Room rework even boosted its capacity, making it more UIM-friendly than ever.

Cost-Effectiveness

At a base cost of 50,000 coins and minimal material investment for early tiers, the Costume Room is one of the cheapest ways to boost your POH’s functionality. Compare that to a Gilded Altar (1M+ coins) or Portal Nexus (millions more).

In conclusion, the OSRS POH Costume Room is an underrated gem that blends practicality with flair. Whether you’re saving bank space, organizing your clue haul, or just showing off your cape collection, it’s a feature worth building. So grab some planks, hit that workbench, and transform your house into a storage powerhouse. Happy scaping!
