A curved stair lift costs $8,000 to $20,000 installed, according to Fixr's national data, compared with $2,000 to $8,000 for a straight lift. The rail is designed and made for one staircase, which is why curved lifts are the most expensive type and take longer from order to fitting.
How much does a curved stair lift cost?
Expect $8,000 to $20,000 installed.[1] Fixr describes curved stair lifts as the most expensive kind because they must be designed to negotiate the curves of your staircase, and they can take longer to install or need more costly materials.[1]
| Type | Typical installed cost |
|---|---|
| Straight | $2,000 to $8,000 |
| Standing | $2,500 to $10,000 |
| Outdoor | $4,000 to $12,000 |
| Curved | $8,000 to $20,000 |
What makes one curved lift cost more than another?
- The number of turns, and whether the stairs spiral
- Whether the rail must extend past the top or bottom step to park out of the way
- Intermediate landings that need a level stop
- Seat options such as a powered swivel
- Outdoor use, which needs weather-resistant parts
Who should fit a curved stair lift?
Fixr says curved stair lifts are more complicated to install and the job should be entrusted to the manufacturer.[1] Ask who surveys the stairs, who makes the rail and who services it afterwards.
How can you lower the cost?
If a flat landing splits the stairs into two straight flights, two straight lifts may cost less, provided the rider can move safely between them. A home with space for a through-floor lift is also worth comparing, especially if a wheelchair may be needed later.
What this means for you
If your stairs turn at all, budget $8,000 to $20,000 and ask for the survey method, the lead time for the rail and the warranty in writing before you order.

Frequently asked questions
Why is a curved stair lift so expensive?
Each rail is designed for one staircase, may need more costly materials and takes longer to install, according to Fixr.
Can you buy a used curved stair lift?
Rarely, because the rail only fits the staircase it was made for. The chair can sometimes be reused on a new rail.
Is there a cheaper option for stairs with a landing?
If the landing is flat and roomy, two straight lifts can cost less, but the rider must change chairs on the landing.
