The Oak door is a door that can be made in the dungeon of a player-owned house with the Construction skill. Building an oak door requires at least 74 Construction and 10 oak planks. Constructing these is recommended for training instead of oak larders once the level requirement is reached. When made with the Butler it is possible to make 500k experience per hour with sacred Clay Hammers, or 250k experience per hour without.

At current Grand Exchange prices, it costs 5,590 coins to build an Oak door. This is 9.32 coins/XP (without a Sacred clay hammer). With the use of a butler and a sacred clay hammer, training with oak doors costs 4.92 coins/XP or 4.85 coins/XP after completing Love Story.

Opening the door

• When the door's lock is picked, the user receives 10 Thieving experience.
• When the door is forced, the user receives 10 Strength experience.
