This is a question that our clients ask us almost every day.
The cost of a modern floating staircase can vary from $ 4,000 for the very basic design up to $ 40,000 and more for the best luxury all-glass cantilever staircase. The suspended steel staircases are the cheapest with an average cost from $ 4,000 to $ 6,000 depending on their layout and material. The straight flight floating staircase is the most popular and also the most cost effective. The railing style play an important role when calculating the floating staircase price, often called cantilever staircase. A simple steel railing fitted on one side of the staircase is much cheaper than a toughened glass railing. This is due to the cost of the raw material but also to the engineering involved in the manufacturing.
Floating central spine staircases – the price of a floating staircase

All you need to know before choosing your floating staircase is explained in our article “How do floating staircases work”. Depending on the structural elements of your building we can design different systems to reach the floating effect you want. Some of our client are happy to have a steel central spine as structural support under the treads and they consider this design as a floating staircase. We call this design quasi-floating staircase as the steps are not really suspended but supported by a structural element (the central spine). With a steel railing the average price of this quasi-floating staircase is around $ 4,500.

Other possible designs are a zig zag steel stringer fixed to wall and painted in the same colour as the wall, to make it almost invisible. This is a good cost effective option. The price of this floating staircase is around $ 4,700.

This floating staircase design does not need any supporting element or stringer. The steps are fixed to wall on one side and to the ceiling on the opposite side with stainless steel hangers that serve as railing too. The price for this option could be around $5,500.
Real Floating staircases
Suspended staircase at average prices – The price of a floating staircase
What we believe to be the “real” floating staircase system is the one with a steel structural cantilever element hidden into the wall. This gives a very strong and rigid staircase also with glass railing. In this case the floating stairs price is higher and vary from $ 8,000 to 14,000 $ depending on the type of railing and staircase layout.
Structural glass floating staircases
Suspended high value staircases
Here we come to the king of the cantilever staircases: The all-glass floating staircase. The cost of this design is high because there is a lot of engineering involved both in the design phase and also during manufacturing. The glass panels serve as structural support for the whole staircase and have to be manufactured following structural engineering calculations to be sure they resist to the staircase load requirements. If you go for this staircase design option you need to take into account that for the staircase installation you will need manpower and proper tools to handle the glass which is really heavy. The average price of an all-glass staircase could start from $ 15,000.
