How to determine if your staircase is straight or curved
The single most important question in stair lift selection is whether your staircase is straight or curved. This determines which type of lift you need and significantly affects cost.
Straight staircase: Goes directly from one floor to another in a single uninterrupted run with no turns or curves. One straight line from bottom to top.
Curved staircase: Has any turns, curves, spirals, or intermediate landings (flat sections between flights). If your staircase changes direction at any point, it is curved.
Straight stair lifts
Straight stair lifts use standard rail systems that are cut to fit your specific staircase length. Because they use standardized parts, they are less expensive, more widely available, and have faster installation and delivery times.
- Cost: $3,000–$6,000 installed in Florida
- Installation time: 2–4 hours
- Delivery time: 1–2 weeks typically
- Resale value: Straight lifts can be removed and resold relatively easily
Curved stair lifts
Curved stair lifts require a custom rail manufactured specifically for your staircase's exact dimensions. Each curved stair lift is essentially a bespoke product, which is why they cost significantly more and take longer to deliver.
- Cost: $8,000–$15,000 installed in Florida
- Installation time: Half day to full day
- Delivery/manufacturing time: 3–6 weeks for custom rail fabrication
- Resale value: Very low — custom rails are specific to one staircase
Intermediate landing staircases
Some Florida homes have staircases with intermediate landings — a flat section between two straight flights. These technically require a curved stair lift rail to navigate the landing, though some installations use two separate straight stair lifts (one per flight) which can be less expensive.
Always have a licensed Florida stair lift installer assess your staircase before purchasing. Measurements and staircase type need to be confirmed in person. An installer can also advise whether a two-lift solution for a landing staircase might be more economical than a single curved lift.
Florida-specific considerations
- Outdoor stair lifts — Florida homes with exterior staircases need weatherproof outdoor models. These are available in both straight and curved configurations at slightly higher cost.
- Hurricane preparation — stair lifts include battery backup that keeps them operational during power outages — important in Florida where hurricanes frequently cause power loss
- Salt air — coastal Florida homes should specify corrosion-resistant hardware for stair lift components
