The Challenge of Small Diameter Spiral Stairs: Comfort and Safety

In the world of interior design and architecture, spiral staircases represent an elegant and functional solution for connecting different floors of a structure.

However, a common challenge faced by many customers involves the installation of small diameter spiral staircases, particularly those with diameters of 100cm or less

Travelability and Comfort Limits

The main concern regarding small spiral staircases is their usability limitation. For example, a spiral staircase with a diameter of 70 cm is not passable. This is because, from the total diameter, we must subtract the space occupied by the railing and the central pole, further reducing the useful space for passage. It is easy to understand that a radius of less than 35 cm does not allow progress in the climb.

Tips for Tight Spaces

For customers who have a limited opening available, which is often designed for the installation of a retractable ladder, our recommendation is to consider an enlargement of the same, if possible. This would allow for the installation of a spiral staircase or space-saving staircase.

For example, for a total height (from the lower floor to the upper floor, including the attic) of 292 cm, the optimal hole for inserting:

• a straight staircase (such as the Mina staircase ) is 60 cm wide by 161 cm long.
• a spiral staircase (such as the Circula staircase, diameter 105cm ) is equal to 110cm wide by 110cm long

However, it is possible to install these ladders in even slightly narrower holes.

Square Spiral Stairs: An Alternative Solution

Another option can be represented by square spiral staircases installed between 3 walls, the 105 version of our spiral staircase has the optimal hole 105cm wide by 110cm long. These stairs offer a unique design that can better fit certain spaces, while still providing a smoother passage than a circular staircase of equivalent diameter.

Conclusion

In conclusion, while small diameter spiral staircases may seem like an attractive solution for tight spaces, it is essential to consider safety and comfort aspects. We advise our customers to carefully evaluate the dimensions of their spiral staircases, opting for dimensions that do not compromise practicability and safety. In case of doubts or structural limitations, our team is always available to provide advice and tailor-made solutions.
