Spiral Stair Layouts
Click on the following diagram to see the layout of the spiral staircases in each diameter and both rotations.
The Optima Spiral Staircase kit can be installed with a clockwise or anti-clockwise rotation. You decide when you fit the staircase!
Please note that the ceiling opening size should ideally be 100mm (4") larger than the diameter of the staircase to ensure that you can use the handrail safely as you travel up the staircase.
The standard kit has 13 risers (12 treads + 1 landing tread) and the tread rise is adjustable from 210mm to 233mm, although UK regulations have a maximum tread rise of 220mm. This means that the standard kit will suit floor to floor heights of up to 3035mm (or 2860mm to comply with UK Building Regulations). If your floor to floor height is higher than this, you simply need to add additional tread kits as required. See the Accessories page for more information.
The individual tread rise is adjusted by adding ingenious shims between each tread to provide your overall correct staircase height. These are supplied in the kit, together with all fixings and fittings required plus clear installation instructions and an installation DVD!
The gap between the vertical spindles on the balustrading of the Optima spiral stair is less than 100mm to satisfy the Building Regulations' 100mm gap rule.
The staircase is delivered direct to you from Italy and the delivery timescale is approx 10 working days.
