Spiral and helical staircases are visually striking but can be challenging to navigate, especially when mobility becomes a concern. Installing a stairlift on these types of staircases is possible, but it requires a curved stairlift designed for this type of staircase.
This page explains how stairlifts work on spiral and helical staircases and what to consider.
Key Takeaways
- Spiral and helical staircases require a curved stairlift
- Rails are custom-designed to follow continuous curves
- Space and clearance are critical factors
- Installation is more complex than standard staircases
- A professional survey is essential
The Short Answer: Can Stairlifts Work on Spiral and Helical Stairs?
Yes, stairlifts can be installed on spiral and helical staircases, but only with a curved stairlift designed specifically for the shape of the stairs. Because these staircases curve continuously, the rail must be custom-made to follow the full spiral.
Not all spiral staircases are suitable, which is why a detailed assessment is required.
What Is the Difference Between Spiral and Helical Staircases?
- Spiral staircases rotate tightly around a central column
- Helical staircases curve gradually without a central column
Both designs require bespoke stairlift solutions.
How Curved Stairlifts Work on Spiral Staircases
On spiral staircases, the rail:
- Wraps around the central column
- Maintains consistent spacing and balance
- Allows smooth, continuous movement
Space and safety clearances are carefully measured.
How Curved Stairlifts Work on Helical Staircases
On helical staircases, the rail:
- Follows the sweeping curve of the stairs
- Adjusts to changing stair width
- Provides stable travel across the curve
These designs often allow slightly more flexibility.
Key Factors That Affect Suitability
Surveyors assess:
- Stair width
- Diameter of the spiral or curve
- Clearance for safe seating
- Entry and exit space
If safety can’t be guaranteed, alternatives may be discussed.
Are Stairlifts Safe on Spiral and Helical Staircases?
Yes when installed correctly. Curved stairlifts include:
- Smooth start-and-stop movement
- Safety sensors
- Swivel seats for safe access
However, suitability depends on the individual staircase.
Installation Time and Complexity
Installing a stairlift on spiral or helical stairs:
- Takes longer to design and manufacture
- Requires precise installation
- Involves thorough testing
This ensures safe, reliable use.
