What Affects the Cost?
The final cavity slider door cost depends on several project and product factors.
Door weight capacity such as 65kg, 125kg or 150kg systems
Wall type such as timber stud or steel frame
Door material such as timber, aluminium or glass
Installation complexity for new builds, retrofit projects, wet areas or tiled walls
Track and hardware quality, including soft-close or automatic options
65kg vs 125kg vs 150kg Cavity Slider Cost
Choosing the right cavity slider system depends on your door size, wall finish, door weight and how the opening will be used. Premium 125kg and Premium 150kg systems cost more than the 65kg option because they are more advanced systems with stronger frames, heavier-duty hardware, smoother operation and a wider range of functional options. The cheapest system is not always the best option for every installation.
Premium 65kg systems are a cost-saving option for standard lightweight internal doors. They are suitable for bedrooms, wardrobes and simple replacement projects where a simple, reliable cavity slider system is required.
Premium 125kg systems are stronger and more advanced than standard 65kg systems. They offer heavier-duty hardware, smoother operation and more functional options, making them a better choice for larger doors, glass or aluminium panels, high-use areas, wet areas and tiled walls.
Premium 150kg systems are the most advanced heavy-duty option in this range. They are designed for larger architectural doors, commercial applications, heavier panels and more demanding installations, with stronger construction, premium hardware options and automatic sliding door options where required.
For wet areas, tiled walls, large door panels or premium builds, Premium Sliding Doors generally recommends using a Premium 125kg or Premium 150kg cavity slider system rather than a standard 65kg cost-saving system.

Are Cavity Sliding Doors Worth It?
Cavity sliders are a popular choice in Australian homes because they save space, improve flow, and provide a modern look. While the upfront cost can be higher than hinged doors, the long-term benefits often outweigh the investment.
Which Cavity Slider System Should You Choose?
If you’re installing a standard internal door and need a cost-saving replacement option, a 65kg cavity slider system may be suitable. For larger doors, glass panels, wet areas, tiled walls or high-use areas, a 125kg or 150kg system provides better strength, performance and long-term durability.
Choose 65kg: standard internal doors, bedrooms, wardrobes and cost-saving replacement projects.
Choose 125kg: wet areas, tiled walls, larger doors, glass or aluminium panels and premium residential builds.
Choose 150kg: oversized doors, architectural projects, commercial applications and heavy-duty installations.
