It is available in 3 colors - black, white, and grey - powder coated - ready to install - clockwise as well as counter-clockwise.

With additional components, this kit can be extended to a maximum height of 12 ft. 4 in. or to a minimum of 6 ft.10 5/8 in. The standard spiral staircase kit has a 360º rotation and by adding or subtracting risers the rotation will change by approx. 30º per riser. Additional riser kits can be purchased separately. The Phoenix stair treads are manufactured from European beech wood, finished with a light natural stain and clear coat protective sealer. To allow for proper installation and full clearance, the finished (round, square or mezzanine) opening for the installation of the spiral staircase must be at least 2 in. greater than the diameter of the staircase kit. To complete your project a balcony rail kit is available. Riser bars are available in a set of 12 to close off the back of the treads.

What is the height between each riser?

Asked by dandelionmd April 27, 2019

The height between each riser is based on the height of the installation and the number of treads used. It is adjustable as the standard kit is adjustable between 99" and 120". You can visit our website at and access the landing page for the PHOENIX model and scroll down to use the staircase builder tool to enter your specific height and dimensions and it will produce a drawing showing the tread positions and the riser height.

can 2 60" stair cases be combined to go from basement floor to a first floor landing and continue...

Asked by Doc January 15, 2019

It is possible to "double stack" the Phoenix spiral staircase if there is an intermediate landing to be able to attach the landing platform at a mid-way point in the install. It is dependent on the exact measurements from finished floor to finished floor of each landing area. To be able to better advise based on the specifics on your installation, please contact our Customer Sales & Support team via our toll free telephone number at (888) 782-4758 and our team will be happy to review the complete details and offer a solution for your consideration.

How flexible is the layout of the steps?

Asked by Jeeve October 7, 2015

The steps can rotate clockwise or counter clockwise but that's about it. From the entry edge at the top of the stairs to the exit step at the bottom is a rotation of about 340 degrees, so your entry and exit directions are approximately the same. So the main question is whether or not you want the exit step to be on the left or the right of the pole as you exit the steps. For example, in the stock picture the bottom exit step is to the left of the pole but I installed mine to the right. When I first fanned out the steps I saw that the rotation was not good, so I simply fanned them out in the opposite direction. Once you put the balusters in, they fix the horizontal distance between the steps and you can't change that. So it will always rotate about 340 degrees to the left or to the right.
