Pricing spiral staircases is often difficult because they are often associated with huge commercial spaces. For this reason, it may seem like they’re out of budget for your home project. However, Salter Spiral Stair offers plenty of designs that fit into a range of budgets.

While all of our spiral staircases are custom designed, we can offer some insight into the factors that will help determine the price for your project.

Dimensions and Measurements

Like many renovation and building projects, the price for your spiral staircase is dictated by the size of your spiral stair.  The quantity of materials needed is the most significant factor when calculating the baseline price, so measuring the height and width of the space before speaking with your consultative designer will lead to the most accurate pricing estimate.

The height of the spiral staircase is determined by measuring from the baseplate (floor) to the desired landing platform.  A code-compliant one-story (or 13-foot) spiral staircase will typically require 15-to-20 treads (steps).  The number of treads will vary based on materials used, the tread shape, the angle of rotation, and the size and shape of the landing platform.  Your consultative designer will help you account for all of these variables after you provide the height measurement.

The width of your space will dictate the size of the individual treads in your spiral staircase.  A wider space will allow for elongated treads while a confined space will require narrower treads.  The width and length of each trend will impact the rotation angle around your column and, once again, your consultative designer can help you navigate this element of your project.

Spiral staircases are functional in a variety of spaces, both indoors and outdoors.  How you plan to use your future staircase plays a significant role when budgeting your project. Depending upon the stair’s location, you’re going to consider different finishes. For instance, an outdoor staircase will require a more durable finish than an indoor staircase.  The materials and finish used in your spiral staircase need to reflect the relative exposure and usage, so understanding your chosen location will help your consultative designer best gauge your estimated cost.

Product Lines

Salter Spiral Stair has different product lines based upon the five available materials. We have three interior options: Classic Steel, Forged Iron, and Solid Wood. We also have two outdoor options: Powder Coated Aluminum and Galvanized Steel. All of these different product lines have their own benefits and should be weighed against their anticipated function when pricing spiral staircases.

Our consultative designers can price your stair design in different materials to find the best fit for your budget.

Access Point

There are two access points that you can use when installing a spiral staircase: at the face of the wall or through a hole in the floor.

A spiral stair is typically installed at the face of a deck or loft with match railing to enclose the space. Your spiral staircase will have a top platform that connects to the face of your deck or loft to create a safe and stable transition between the two.

A hole in floor access point is just like it sounds. You would have an opening in the floor of the upper level that would open to your spiral stair. The hole is enclosed with well opening railing. This is commonly found with spiral stairs that are moving between two floors of the home.
