Spiral Staircases come in many different sizes and styles. How do you know which will best fit your needs? There are several things to consider.
The most popular Spiral Stairs are made of steel. Wood treads & landings, and aluminum handrails are offered as an option. These are your best values, and we have a full line of the most common sizes available for purchase here on SpiralStairWarehouse.com. Spiral Stairs are also available in Oak and Victorian styles, but these styles — while beautiful — tend to be more costly. We currently don’t offer Oak and Victorian styles in our web store. However, if you are interested in learning more about Oak, Victorian, or other Custom Spiral Staircases, we suggest you click here.
Will your Spiral Staircase be indoors, or will it be located outdoors as a means of access to a deck or balcony? If outdoors, you can’t have optional wood treads because they would eventually deteriorate due to rain, snow, or other moist air conditions such as living near the seashore. Instead, consider adding optional galvanized treads. Galvanizing protects your staircase from the elements.
We offer a limited line of the most popular add-on items to accessorize your Spiral Staircase in our online store. Oak Treads and Landing with an Oak Top Cap can provide added beauty and elegance to your staircase. If you prefer standard metal treads, consider our Diamond Plate option for better traction while climbing or descending steps. Single, Double, or Triple-In-Between Spindles on each step add beauty and can improve stability and cut down on the space where children or small objects can “squeeze through the cracks”. Aluminum Scroll Ends for your handrail and Riser Bars under each step make your staircase even more attractive.
Installing your Spiral Staircase is relatively easy, especially if you are experienced in home remodeling or are a handy do-it-yourselfer. Standard tools are required. All kits purchased from the Spiral Stair Warehouse come with detailed, easy-to-understand instructions. There is also helpful information about parts here and a visual assembly tutorial here. If you find installation too daunting, we recommend hiring a local contractor to install your staircase.

All non-galvanized Spiral Stair Kits from the Spiral Stair Warehouse are shipped with a Black Enamel Primer Coat. You can paint your staircase any color you’d like to match your decor. Wait until your staircase is assembled before you paint to avoid scratches that might occur during installation. Always use an oil-based enamel paint — do not use latex paint. Exterior staircases should be painted with an oil-based enamel paint that contains a rust-inhibiting additive. Galvanized staircases must be allowed to weather before painting. Contact your local paint store for an appropriate primer and paint for galvanized surfaces.
Whether your Spiral Staircase is indoors or outdoors, consider how it will be used before you determine the proper diameter of the model you want to buy. Spiral Stair Warehouse offers Spiral Stairs in diameters (widths) ranging from 3-foot 6-inches up to 5-foot 6-inches. These are the most common widths in use today. While our 3-foot 6-inch, 4-foot, and 4-foot 6-inch diameter Spiral Stair Kits are very popular for a variety of uses, consider whether they are the only means of access to an upper floor or balcony. Narrower-width Spiral Staircases can be more challenging when carrying large or otherwise bulky items between floors. And if you have small children or pets that will use the staircase frequently, a wider-width staircase (such as our 5-foot model) may be more desirable.
Regardless of whichever diameter Spiral Stair model you choose, remember that the well opening you must cut in your ceiling (if not installing to a balcony) must be at least 2 inches wider than the diameter of the staircase you purchase.
If your Spiral Stairs must conform to common building codes, you must select our 5-foot diameter or 5-foot 6-inch diameter models. Diameters that are less than 5-foot are not code conforming. Our 5-foot and 5-foot 6-inch staircases come equipped with Triple-in-Between Spindles and a 1 ¼” Aluminum Coil Handrail as standard accessories. Triple-in-Between Spindles conform to code that require less than 4 inches between spindles on each step. The 1 ¼” Aluminum Handrail provides superior stability. Check with your local municipality to find out if building codes are applicable in your area.
All of our Spiral Staircase models are available in heights from 7-foot 2-inches (our 10 Riser model) up to 12-foot 8-inches (our 16 riser model). The number of risers (steps) depends upon the height of the staircase, and is automatically calculated for you in our online store. Call 1-877-782-4779 or contact us if your height falls out of this range.
- Square Well Opening
Your well opening is the square hole you will cut in the ceiling leading to the upper level where the top of your staircase will provide access (or if you’re looking at it from the top down, the square hole in the floor at your feet that you will cut).
If your staircase is leading up to a balcony or deck, you don’t have to worry about a well opening – because there is no “well”.
Occasionally some customers want to have a round well, or a round well may already exist from a previous staircase. Spiral Stair Warehouse kits come standard with square landings, however you can order a special round landing by calling 1-877-782-4779.
- Floor-to-Floor Height
This measurement is the distance between the floor on the lower level of your staircase (where you enter the staircase to go up) and the floor on the upper level of your staircase (where you exit the staircase).
If you have not yet cut a well into your ceiling, you must calculate the distance between the ceiling of the lower level and the floor of the upper level, including the height of your rafters, sub-floor (usually 3/4″ plywood) and the thickness of your finished floor (wood, tile, carpeting, or other).
- Finished Well Opening
A “finished” well opening means the width of the opening after all molding or other finishing materials are applied. Your finished well opening must always be at least 2 inches wider than the diameter of the staircase you order. This is to allow enough room for installation hardware.
In other words, if you order our 3-foot 6-inch diameter staircase, your finished well opening must be at least 3-foot 8-inches wide. Likewise if you order our 5-foot spiral, your finished well opening must be at least 5-foot 2-inches wide.
If you have a round well opening, the same 2-inch rule applies as with the standard square well opening.
- Stair Diameter
Spiral Stairs are available in several different diameters (widths) depending on how much space you have available where your staircase is going to be installed. Spiral Stair Warehouse offers Spiral Stairs in diameters ranging from 3-foot 6-inches up to 5-foot 6-inches. These are the most common widths in use today.
While our 3-foot 6-inch, 4-foot, and 4-foot 6-inch diameter Spiral Stair kits are very popular for a variety of uses, consider whether they are the only means of access to an upper floor or balcony. Narrower-width Spiral Staircases can be more challenging when carrying large or otherwise bulky items between floors. And if you have small children or pets that will use the staircase frequently, a wider-width staircase (such as our 5-foot model) may be more desirable.
Some municipalities require Spiral Stairs to conform to local building codes. If applicable where you live, you must select our 5-foot diameter or 5-foot 6-inch diameter models.
Depending upon the placement of your staircase and the direction in which you enter and exit it, your spiral can be Right-Hand Up (the handrail and spindles for each step are on your right side and the center pole is on your left as you enter the staircase from the lower floor) or Left-Hand Up (the handrail and spindles for each step are on your left side and the center pole is on your right as you enter the staircase from the lower floor).
The handrail and spindles are on the opposite side as you descend down the staircase from the upper floor.
Whether you choose Right-Hand Up or Left-Hand Up makes no difference in the price of your Spiral Stair Warehouse kit. There is no additional charge for one versus the other.
