Types of Stair Lifts
Stair lifts are available for straight, curved, and outdoor staircases. The type of staircase is the biggest cost driver.
Straight Stair Lift
$2,500–$5,000 installed
For staircases with no curves or landings. The most affordable and quickest to install.
Curved Stair Lift
$8,000–$20,000 installed
Custom-built rail to follow the exact curve of your staircase. Each unit is made to order.
Outdoor Stair Lift
$3,000–$8,000 installed
Weather-resistant models for exterior steps. Require UV-resistant covers and weatherproof components.
Standing / Perch Lift
$3,000–$6,000 installed
For users who have difficulty bending their knees. The user stands or perches rather than sits.
What Installation Involves
Home Assessment
Installer measures the staircase, assesses the user's needs, and recommends the right model. Curved lifts require precise measurements for custom rail fabrication.
Rail Installation
The rail is mounted to the stair treads (not the wall), so no structural modification is needed. Straight rails arrive ready to install; curved rails are custom-fabricated.
Electrical Connection
Most stair lifts plug into a standard 120V outlet. A dedicated circuit is recommended. Battery-powered models charge from the outlet and work during power outages.
User Training
Installer demonstrates safe operation, remote controls, swivel seat, and safety sensors. Most lifts have obstruction sensors that stop the unit if something is in the way.
