Custom stairs in Bellevue and Renton, WA
Custom Floating Stairs in Bellevue and Renton, WA
Open risers, clean lines and treads that seem to hang in space. West Coast Stair Co. designs and builds custom floating stairs for homes across Bellevue, Seattle and the Eastside, handcrafted in our Renton shop.

What makes a floating staircase different
A floating staircase replaces the closed stringers and solid risers of a traditional stair with an open, minimal structure. Light and sightlines pass through the stairwell, which suits modern, contemporary and open-plan homes.
With so little structure to hide behind, the quality of the fabrication, fit and finish is on full display. That is why we build each floating stair around your home's architecture instead of fitting a standard product into it.
What we build
- Custom floating stairs with wood treads in species and finishes selected for your home
- Steel and metal stair and stringer options, including through our Prestige Metal resource
- Glass, cable and metal railing details that suit an open design

Frequently asked questions
What is a floating staircase?
A floating staircase uses an open structure with individual treads, so the stairs appear to hang without solid risers or a closed stringer. It creates an airy, modern look and keeps the stairwell open.
Can floating stairs be added to an existing home?
Yes. For remodels, we evaluate the existing space, photos and your design goals. Every floating stair is designed around the home, so feasibility depends on the structure and layout, which we review during your consultation.
Where are your floating stairs built?
Every component is designed and handcrafted in our fabrication shop in Renton, WA, then installed in homes across Bellevue, Seattle and the Eastside.
