When planning a renovation or new build, one of the most common questions we hear is: “How much do custom internal sliding doors actually cost?” The answer isn’t always straightforward—and for good reason. Custom door manufacturing involves many variables, each contributing to the quality, performance, and overall finish of the final product.

Whether you’re specifying interior sliding doors or cavity sliding doors, understanding the key factors that influence pricing will help you budget accurately and deliver the best outcome for your client.

1. Door Type: Flush Panel, Joinery, or Veneer?

The base door type is the first major cost driver:

Flush Panel Doors

A cost-effective and versatile choice, flush panel doors suit most contemporary homes and commercial spaces. They can be produced in a variety of finishes, from paint-grade MDF to premium laminates.

Joinery Doors

These are traditionally built from stiles and rails with inset panels. They offer architectural character and are often chosen for high-end homes or statement entrances.
Because they involve more craftsmanship and more complex construction, they sit at a higher price point due to the design complexity and labour time involved.

Veneer Doors

Ideal for achieving the warmth of natural timber without the weight or cost of solid timber. Veneered doors are popular for premium interior fit-outs, especially when paired with matching timber reveals or architectural door hardware.

2. Door Construction: What’s Inside Matters

The internal construction of the door plays a significant role in both performance and pricing. Options include:

• Semi-solid Core – Lightweight and budget-friendly, suited for standard residential use.
• Solid Core – Offers improved acoustic performance and a sturdier feel. Often specified in multi-residential and commercial builds.
• Solid Timber – Premium, durable, and ideal for feature timber sliding doors, but naturally more expensive.
• Glass or Glazed Inserts – Adds natural light and enhances architectural appeal.

For projects involving cavity sliding doors or concealed track systems, the door construction must also be compatible with the selected hardware.

3. Door Size: Standard vs. Custom

Moving beyond standard heights and widths significantly affects cost.
Floor-to-ceiling architectural designs, wider openings, and oversized panels require:

• Stronger cores and sturdy sub-frames
• Reinforcement in top and bottom rails for hardware cutouts
• Specialised manufacturing processes
• Additional labour for handling and prepping for hardware
• Additional packaging or specialised freight services to ensure safe delivery of door

These custom elements contribute to the premium often associated with designer interior sliding doors.

4. Door Preparation: Hardware, Glazing & Detail Work

This is where cost variations can become more significant. Custom preparation may include:

• Routing for sliding door hardware or concealed tracks
• Pivot hinge cut-outs
• Rebate and edging work
• Glazing cut-outs or glazing beads
• Mouldings
• Machined grooves or patterns

Each step adds precision, time, and specialised skill—especially in premium architectural projects.

So… What Do Custom Internal Doors Cost?

Because every project differs, providing an exact figure without reviewing the requirements is difficult. However, most custom internal doors fall within this range:

From approximately $500 + GST anywhere through to $10,000 + GST per door.

Pricing depends entirely on the combination of materials, size, hardware preparation, glazing, craftsmanship, and architectural complexity.

Builders will typically find simpler flush or hollow-core doors at the lower end, while architects specifying full-height joinery or glazed feature doors—particularly in premium internal sliding doors or cavity sliding doors applications—will see costs increase.

Final Thoughts

Custom doors offer designers, builders, and homeowners the ability to tailor every aspect—from materials to mechanics—to elevate the functionality and aesthetics of a space. While the cost range is broad, understanding the factors behind the pricing helps ensure the right door is selected for the right application.
