Vintage warmth in an Antique Brass Mushroom Mortice Knob

The Mushroom Mortice Knob in Antique Brass brings rich vintage charm to any door. Because antique brass has a warm, aged tone, it adds instant depth and character. The mushroom-shaped design feels smooth and comfortable in the hand, while the gentle curves suit older homes as well as modern interiors that need a touch of warmth.

Solid brass core with refined turning action

Although the surface carries an aged look, the knob is crafted from solid brass. This provides durability, reassuring weight and long-lasting performance. Each turn feels smooth, and the aged finish softens further over time. Since antique brass ages naturally, it develops a unique patina that enhances your interior rather than detracting from it.

Mushroom Mortice Knob coordination with Old English finishes

This Harrogate design pairs beautifully with warm metals across the Old English range. For a consistent look, explore the Antique Brass Old English range.
Because antique brass blends naturally with polished tones, it also pairs well with the Polished Brass collection.
These combinations allow you to create a warm, unified theme across multiple rooms.

Easy installation with flexible door pack options

Installing your Mushroom Mortice Knob is simple, and our three door packs make the process even easier. Each pack includes hinges, a spindle and all required fixings.

  • Latch Pack (3” or 4”) – Great for doors that do not need locking.

  • Bathroom Pack (3” or 4”) – Includes a turn & release and deadbolt for privacy.

  • Lock Pack (3” only) – Ideal for bedrooms or studies that require key access, complete with keys and escutcheons.

You can choose between Grade 7 fire-rated hinges or Grade 13 fire-rated hinges, both supplied in packs of three. This ensures your installation is secure and consistent with your chosen finish.

Antique brass finish with warm expressive depth

The mushroom shape brings gentle comfort and timeless simplicity. Meanwhile, the antique brass finish adds soft depth that changes beautifully with natural and artificial light. Its mellow tones bring warmth to bedrooms, hallways and living spaces. Because the finish ages gracefully, it creates a relaxed, lived-in feel that complements traditional and rustic interiors.
