Shaftless vs. Shafted Elevators: Which is Best for Your Home?

From simple two-story constructions to high-rise condos, residential elevators are an essential home accessibility solution for seniors with mobility issues. However, with seemingly countless home elevator models to choose from, it can be difficult for senior homeowners to find the best option. After all, do you need a small footprint or additional weight capacity for a wheelchair?

When comparing different types of elevators, one of the most prominent things to consider is whether the model requires a shaft or not. Both shafted and shaftless systems have unique pros and cons that impact your existing home, monthly expenses, and overall accessibility.

Below, we’ve compared these two distinct types of home elevators, along with the specific models they encompass, so you can find the best residential lift for your situation.

What is a Shafted Elevator?

Shafted lifts, or traditional elevators, require a dedicated elevator shaft to operate. In new construction, an area is measured and framed to house the elevator, while in existing homes, a space between floors is carved out and carefully renovated. Inside the enclosed shaft, the elevator car, powered by either a traction or hydraulic system, travels on guide rails.

While needing to carve out this space is an expensive, upfront investment, operating within the elevator shaft allows the car to travel multiple stories, support higher weight capacities, and offer smoother, more stable rides. Their installation is also highly customizable, allowing senior homeowners to choose from a wide range of car sizes, door styles, and interior finishes.

Types of Shafted Home Lifts

Generally, the two most common types of shafted elevators are traction and hydraulic drive systems. Both have unique pros and cons:

• Traction elevators: The elevator shaft and car are fitted with a motor, a pulley (sheave), a counterweight, and steel cables to provide lift. The motor and pulley raise the elevator along guide rails inside the shaft, while the carefully balanced counterweight reduces the amount of energy needed to move the car. This makes traction systems more energy-efficient and eco-friendly than their hydraulic counterparts, while achieving the highest possible travel distances.
• Hydraulic elevators: Instead of counterweights and cables, these systems use pressurized hydraulic fluid (usually oil) to lift and lower the elevator car inside the shaft. An electric motor powers a hydraulic pump that forces fluid into a cylinder, moving the piston that raises the car. To descend, the system releases the fluid back into where it’s typically stored. The resulting powerful lift and smooth ride are ideal for carrying wheelchairs and other heavy loads.

What is a Shaftless Elevator?

Shaftless elevators are perfect for tight spaces because they eliminate the need for a costly, intrusive elevator shaft. In fact, these installations move between floors without even demanding a separate machine room.

Instead, a small cutout with guided rails, just big enough for the elevator car, is made between floors, so minimal renovation is required. Depending on the type of elevator, the car is powered either electrically or through specialized air pressure systems (PVE). Built-in safety systems and interlocks keep seniors secure by providing emergency stops, power outage backups, and more.

This overall design makes shaftless elevators more space-saving and simplifies the installation process, but comes at the cost of reduced weight capacity and travel distance.

Types of Shaftless Home Lifts

No shaftless home elevator requires a full-height enclosed shaft, instead relying on self-contained support structures and floor cut-outs. Three of the most common types you’ll see in a modern home include through-the-floor elevators, pneumatic elevators (PVE), and vertical platform lifts (VPLs). Each comes with distinct benefits and limitations:

• Through-the-floor elevators: Popular for two-story homes, these compact lifts travel through a precisely cut floor opening, supported by a small guide rail system. When not in use, the opening is sealed with a safety lid or panel. This option offers quick installation, minimal structural changes, and a small footprint, but has a lower weight capacity and usually only travels between two floors.
• Pneumatic elevators: PVEs are self-supporting systems that don’t require a pit, machine room, or hoistway to function. Instead, they use air pressure and vacuum technology to raise and lower the cab within a clear vertical tube. Removing air from above the cap creates a pressure difference that causes lift, while gradually releasing air back into the chamber creates a smooth descent. The result is an energy-saving system that’s fast to install, takes up minimal space, and is also one of the most expensive shaftless options.
• Vertical platform lifts: Often referred to as wheelchair lifts, VPLs are a stair-lift alternative that’s often installed right next to the staircase—both indoors and outdoors. They can be an open or enclosed platform that moves between two floors along a mast or guide column. They’re often the most affordable shaftless option, but travel fewer floors, move more slowly, and lack the finished cab feel of a traditional elevator.

Shafted vs. Shaftless Elevators: Pros and Cons

Deciding between a shafted or shaftless elevator installation? Understanding the unique pros and cons of each type can help you and your loved ones make an informed decision:

Shafted Elevators

Pros

• Higher weight capacity: Shafted elevators, and especially hydraulic drive models, provide strong lifting power that can easily support wheelchairs, several passengers, and other heavy loads.
• More travel distance: Generally have better travel distance capabilities, with hydraulic lifts capable of reaching 60 feet (4-6 stories), while traction lifts can travel well over 100 feet.
• Smoother operation: Associated with smoother movements and faster speeds that improve the quality of life while aging in place.
• Increased home value: Built-in, permanent home features that resemble commercial lifts, potentially increasing resale value in areas with a high senior population.

Cons

• Space-consuming: Requires a dedicated elevator pit and shaft, and potentially a separate machine room, making them less viable for homes with limited space.
• Less energy efficient: Uses lifting mechanisms that require more electricity over time (1.0–5.0 kWh/day) than shaftless models, raising long-term utility costs.
• Complex installation: Building a pit, shaft, and machine room not only takes longer but requires more structural modifications, permits, and inspections. This means shafted installations are usually more costly, disruptive, and time-consuming.

Shaftless Elevators

Pros

• Energy efficient: Both through-the-floor lifts and PVE installations are more energy-efficient than traditional options, consuming only 0.5–1.5 kWh/day on average.
• Space-saving design: Shaftless elevators require neither a shaft or a machine room to function, giving them a compact design that works well in small buildings or areas where the underlying structure can’t be changed.
• Less maintenance: Compact and less complex parts require less maintenance and eliminate risks associated with oil leaks, fluid replacement, cable adjustments, motor servicing, and pulley or counterweight repairs.
• Cost-effective installation: Avoiding structural changes means that retrofitting a shaftless elevator into your existing home is faster and more cost-effective than other options.

Cons

• Reduced travel height: Through-the-floor elevators and VPLs are only reliable for travel between two floors, and even advanced PVE installations can’t rise above 50 feet.
• Lower weight capacity: While VPLs are designed to handle wheelchair transport between two floors, most shaftless systems have a lower weight capacity than shafted options.
• Slightly Rougher Ride: Despite the potentially panoramic views, most models have slow, jerky, and noisy rides compared to shafted lifts.

Which Type of Elevator Is Best For Your Home?

The best residential elevator installation for your home depends on your budget, mobility needs, the available space, number of floors, and more. Here are some questions to ask yourself before you invest:

1. How much space do I realistically have?

Take a close look at your home’s layout, measurements, and underlying structure. Shafted lifts need a minimum of 5×5 feet (25 sq ft) for the shaft, 8-12 inches for the pit, and between 7-10 feet of overhead clearance. All of this construction can be expensive and difficult in homes with limited space, so we generally recommend shaftless lifts for smaller homes, and shafted options for high-rises or new construction.

Reaching out to a professional elevator company for measurements and recommendations is also helpful here.

2. How many floors will the elevator need to serve?

Do you live in a high-rise condo or a two-story suburban home? Traction elevators have a maximum travel distance of over 100 feet, making them the go-to solution for buildings with many floors. However, given that most homes only have one to three floors, VPLs and through-the-floor elevators are both more affordable ways to address mobility concerns.

3. What are my current and future mobility needs?

Beyond assessing your current needs, you should also consider future accessibility. If you’re currently disabled and already rely on a wheelchair, caregiver, or important medical equipment, investing in a high-weight-capacity shafted elevator or VPL helps you age in place safely. However, even if you’re not currently disabled, investing in a heavy-duty system now can save you time and money if you face health concerns later on.

Otherwise, if you have lighter mobility needs and don’t suspect these needs growing in the future, it’s often beneficial to save money on an easy-to-install, shaftless system.

4. What is my upfront and long-term budget?

When it comes to installing a residential elevator, ongoing expenses matter as much as the initial installation cost. Those on a budget often consider shaftless options because they’re not only more affordable to install, but also consume less energy and have fewer long-term maintenance requirements. On the other hand, shafted elevators can last longer (up to 30+ years with proper maintenance), reducing the risk of needing a replacement for seniors aging in place.

Our Takeaway: Shafted and Shaftless Elevators Fit Different Homes, Budgets, and Mobility Needs

Both shafted and shaftless elevators are worth it in certain homes, especially for seniors with mobility issues. However, the best installation for your situation depends on several factors, including whether you need it to travel more than two floors, support a wheelchair, or meet limited space requirements.

Shaftless lifts are an excellent choice for seniors with limited budgets who only need to travel short distances, while shafted elevators provide a higher weight capacity and travel distance for those who need it. Ultimately, reaching out to local, trusted elevator companies can help you determine the best lift based on its requirements and safety features.
