Floating Staircase vs Kit Systems: What’s the Difference?

Most people don’t realize there are two very different ways to build a floating staircase. Some systems are sold as pre-engineered kits designed for standard layouts and simplified installation. Others are fabricated specifically for the space they’re going into.
Understanding the difference between the two is important—not just for cost, but for how the staircase fits, installs, and performs long-term.
If you're also comparing options based on budget, you can see what most floating staircases cost in this breakdown.
At Iron Timbers, we build custom-fabricated floating staircase systems designed specifically for each space—not pre-engineered kits.
What is a kit-based floating staircase?
Kit-based floating staircases are pre-designed systems built around standard dimensions and components.
These systems are typically:
Manufactured in set sizes
Designed to fit a range of common layouts
Packaged with standardized hardware and components
Because they are built for repeatability, they can be a more accessible option for straightforward projects.
Installation is usually handled by a contractor or, in some cases, a capable homeowner, depending on the complexity of the system.
What is a custom-fabricated staircase system?
Custom-fabricated staircase systems are built specifically for the space they’re going into.
Instead of adapting a standard kit to fit the opening, the system is designed around:
Exact field dimensions
Structural conditions
Desired layout and design details
This approach allows for tighter fitment, more flexibility in layout, and a more tailored final result.
At Iron Timbers, our systems are built using a refined process that balances customization with efficiency—delivering a high-end result without the unpredictability of fully one-off builds.
Key differences between kit and custom systems
Fit and precision
Kit systems are designed to work within a range of dimensions. Custom systems are built to match the exact opening.
Installation process
Kit systems are assembled on-site using pre-packaged components. Custom systems arrive pre-fabricated for more straightforward installation. These differences can also impact overall cost, especially when comparing labor and installation time. You can see what floating staircases cost here.
Material and build quality
Kit systems often use standardized materials and components. Custom systems allow for higher-end material selection and detailing.
Design flexibility
Kit systems are limited to predefined configurations. Custom systems can accommodate unique layouts, landings, and design goals.
Railing systems and integration
Kit-based stair systems often use standardized railing components that are designed to be adjusted on-site to fit a range of stair layouts. These systems typically arrive as multiple parts that are assembled and modified during installation.
Custom-fabricated systems take a different approach. At Iron Timbers, our railing systems are designed and built specifically for each staircase using steel—not standardized components. Every railing is laid out and fit in-house before shipping, ensuring it integrates cleanly with the staircase itself. This eliminates guesswork on-site and results in a tighter, more precise finished system.
This level of integration also plays a major role in safety and long-term performance. You can read more about how floating staircases are engineered for safety here.
When a kit system makes sense
Kit systems can be a good fit for:
Straightforward layouts
Budget-conscious projects
Situations where speed and simplicity are the priority
For the right application, they can provide a clean look without the need for full customization.
When a custom system makes sense
Custom systems make more sense when:
The layout includes turns, landings, or unique conditions
Fit and finish are a priority
The staircase is a central design feature
Long-term durability and performance matter
They’re also a better fit when the goal is a seamless integration into the home rather than adapting a system to fit.
The real decision
Choosing between a kit system and a custom-fabricated staircase isn’t just about price.
It comes down to how well the system fits the space, how it installs, and how it performs over time.
Both options can work—but they serve different types of projects.
For most homeowners and builders, the choice comes down to whether you want a system that adapts to your space—or one that’s built specifically for it.
If you're weighing cost, safety, and long-term performance, understanding these differences is key before making a decision.
