TOP TIPS

The pitch height can be adjusted with spacer rings from 19 to 23.5 cm depending on floor height. We advise you use as little spacers as possible as this will mean narrow gap between the treads, this will make your staircase more comfortable to climb.

SCULPTURE BEAUTY - these spiral stairs are easy to install with minimal heavy components. No special tools are required.

The Sigma spiral staircase comes in both 120cm and 140cm - pick the required height from the dropdown.

To give an example the spiral staircase SIGMA Ø 120cm only requires an opening of 125cm x 125cm or a round ceiling opening of 130cm. In general, subtract 10cm from your ceiling opening to get the right diameter of your new staircase.

Please consider window or door locations as well as radiator locations to prevent assembly issues. For wall niches please note the entry and exit points and be aware that the optimal ceiling opening is 10cm larger than the staircase diameter.
