At The Great Lakes Stair & Millwork Co., we get a wide variety of requests for many different styles of spiral stairs. We have designed and built many of these aesthetically different and exceptionally functional spiral staircase systems in the last 30 years of our extensive history. However, we have found that many people use the term “spiral stairs” almost generically, the same way the terms “tissue” and “Kleenex®” are often interchanged. We would like to take this opportunity to talk about spiral stairs, their advantages, and disadvantages, and how they are different from other circular, curved, or helical staircase systems.
The term “spiral stair” is widely used to describe a turning staircase such as a curved stair, circular stair, radiused stair, or a round stair. The implication is a staircase that does some type of radius turn. The actual definition of a spiral staircase is the following:
Other turning staircases can be defined as:
Thus, the key differentiator between a spiral staircase and other types of turning stairs is that a spiral staircase wraps symmetrically around a center pole.
Spiral staircases are ideal when used for ease of personal access in a small area. With a standard 5’-6” finish square opening, we can do a lot with a spiral staircase to traverse between floors with ease. Additionally, spiral staircases are great conversation pieces as they are aesthetically different from perpendicular or traditional staircases. You typically do not see spiral staircases all the time in the design of a home, so they tend to stand out when implemented.
If designed, constructed, and used properly, spiral stairs can be a beautiful and safe addition to your home or business and serves a highly functional and extremely aesthetic purpose.
What are the disadvantages of a Spiral Stair?
For the most part, a spiral staircase is an easy, attractive alternative to access a floor level in your home while utilizing minimal space. But spiral stairs do have a few minimal disadvantages. We feel it is our responsibility as a Senior Stair Manufacturer in the United States to make you aware of any potential issues you may (OR MAY NOT) encounter with the addition of a spiral stair in your home or project:
While none of the above (potential) disadvantages of a spiral stair are monumental, it is only fair to make people aware that they could encounter none, some, or all of the above while determining if a Spiral Staircase System is right for them.
Typically, spiral staircases are constructed using all wood, all metal, or made with a combination of these materials. Additionally, spiral staircases can incorporate glass or decorative iron or both. Check out our spiral stair gallery for a wide variety of examples of spiral staircases we have created at Great Lakes Stair.
The cost for a spiral staircase, like any other staircase is relative to the overall design and materials used in the construction as well as installation considerations. You can design and build a cost effective spiral staircase, or a luxury model incorporating the finest materials available. At Great Lakes Stair we will work closely with you and discuss your needs and evaluate your space and propose a spiral staircase solution that works for your home and your budget.
The average spiral stair diameter is 5’-0”. This is predominantly the most widely used size for spiral stairs. The 5’-0” diameter meets most uniform building codes around the United states and neighboring countries for code adherence / compliance. This stair fits comfortably in a 5’-6” finish square or round opening.
Typical Spiral stair diameters can start out utilizing a 4’-0” diameter (we have even completed a 3’-6” diameter spiral stair for a Doll house), but can be made to virtually any diameter up to 12’-0”. After 12’ in diameter, you would be better off putting in a circular stair. The Most common spiral staircase sizes and their respective finished openings they fit in, are as follows:

How is a Spiral Stair delivered to my project or home? How do I get it inside the home?
These are great questions and also are great concerns when purchasing a Spiral Staircase system. We have all heard the horror stories of fully assembled spiral stairs arriving at a home or jobsite with no ability to get the stair inside structure. For most applications, this process of fully assembling spiral stairs prior to arrival and delivering them completely welded or fabricated in whole, is nothing short of a catastrophic disaster. Just the logistics, packaging, additional shipping costs and potential damage that usually does occur with a fully welded or pre-fabricated spiral stair, should dissuade anyone from going that route of buying a fully assembled spiral stair.
We at the Great Lakes Stair Company do things differently than other manufacturers. Most of our spiral stairway applications will be pre- built in our shop to ensure fit and finish and then disassembled in simple sections, numbered, and labeled for ease of final jobsite installation. The stair will then be carefully packaged on a “skid”, wrapped in protective cardboard, and shipped directly from our facility to your home or project. We can arrange for tailgate delivery anywhere in the US or neighboring Countries. From here, all you need is one person to carry the lightweight sections through a 2’-6” or larger door into the room or area where the spiral stair will be installed and then reassemble. Two people are required for stair assembly, one to hold the center pole, the other person to slide the sections over the center pole.
It’s that easy!
In general, most spiral stairs can be final assembled and installed in less than a 1 day.
With over 30 years of experience in producing and installing spiral staircases, we know exactly what questions to ask about your project and through our experience, will understand your needs as a consumer. We will collaborate with our customers by sharing photos, evaluating your space, understanding your specifications and then, turn your ideas into reality. We do not produce any base or entry level products as all of our spiral staircase solutions are semi-custom to all custom designed and hand fabricated projects. Remember, one size does not fit all when it comes to spiral stairs. The inexpensive commodity spiral stair market and cheap prices will only lead to continuing problems. We routinely replace commodity spiral stair case kits that were poorly constructed and/or installed by unqualified individuals.
Please give us a call when you are considering purchasing a spiral staircase. The specialists at The Great Lakes Stair Company will ensure you get the right spiral stair for your needs, at the right price for your budget. Along with our optional expert installation we ensure a spiral staircase project that will be trouble free and will last for generations.
