Straight Stairlift vs. Curved Stairlift
The single biggest factor in stairlift cost is whether the staircase is straight or has curves and landings, since curved rails require custom fabrication.

Straight Stairlift
A stairlift for a staircase with no curves, turns, or landings, using a standard-length straight rail.
- Significantly lower cost given standardized rail parts
- Generally faster to install, sometimes within a day
- Only works for a genuinely straight staircase run
Curved Stairlift
A stairlift with a custom-fabricated rail designed to follow a staircase's specific curves, turns, or landings.
- Works for staircases a straight-rail unit simply couldn't accommodate
- Custom-built to precisely fit the staircase's actual shape
- Significantly higher cost given custom rail fabrication
- Longer lead time since the rail must be custom-built and measured
Which one makes sense for you?
A straight stairlift costs significantly less and installs faster, since it uses standardized rail parts. A curved stairlift costs considerably more and takes longer due to custom rail fabrication, but is the only option for staircases with turns or landings — there's no way to substitute a straight-rail unit onto a curved staircase.
Key cost factors.
- Actual shape of the staircase — straight run versus curves or landings
- Budget available given the significant cost difference
- Lead time tolerance for custom rail fabrication if curved
- Whether a reconditioned unit is an option (more common for straight lifts)
Before you decide.
- Does our staircase have any curves, turns, or landings, even minor ones?
- What's the realistic lead time for a curved rail given custom fabrication?
- Is a reconditioned unit available for our situation to reduce cost?
Frequently asked questions.
Is a landing partway up a staircase considered curved or straight?
A landing generally requires a curved or custom rail solution, even if the two staircase sections on either side of it are individually straight, since the rail needs to navigate the change in direction at the landing.
