90° overhang edge
The front of the tread extends past the riser face, creating a shadow line and a clean, defined edge that reads well in any interior.
The most widely used stair tread profile in residential construction — a clean, square overhang that covers the riser face and gives any staircase a sharp, finished edge. Compatible with every flooring material FIR installs.
The standard square nose has a 90-degree front edge that overhangs the riser face by roughly an inch. That overhang hides the riser-to-tread joint, creates a defined stair edge, and gives the step a traditionally finished appearance that works in any home style — from craftsman to contemporary.
The front of the tread extends past the riser face, creating a shadow line and a clean, defined edge that reads well in any interior.
The overhang sits over the top of the riser board, hiding the joint between the two surfaces for a seamless vertical-to-horizontal transition.
LVP, hardwood, engineered wood, and vinyl plank can all be finished with a square nose profile. FIR matches the tread to the floor you already have or are installing.
The square nose is the default for a reason — it handles high foot traffic, holds up in Florida humidity, and requires no special framing or structural modification to install. For most stair makeovers, it is the correct and cost-effective choice.
When installed with hardwood, engineered wood, or quality LVP, a square nose tread resists scuffing, denting, and surface wear from daily household use.
Neither modern nor dated, the square nose reads cleanly in traditional, transitional, and contemporary interiors. It complements rather than competes with the rest of the design.
The square nose installs over the existing stair substrate without rerouting framing, adjusting stair height, or modifying the riser system — making it the most efficient profile for makeovers.
FIR selects tread material based on what you have on the floor or what you are installing. The goal is for the stair and the floor to read as a single coordinated system — same color family, same sheen, same visual weight. Square nose treads are available in LVP stair planks, solid hardwood, and engineered hardwood depending on the project.
LVP stair planks with a square nose profile offer the best moisture resistance for Florida homes. They pair seamlessly with LVP flooring and require less maintenance than wood.
Solid hardwood treads with a square nose edge add warmth and natural grain variation. Best suited for homes with hardwood or engineered wood floors on the same level.
Engineered hardwood treads hold their shape better than solid wood in Florida's humidity. Available in the same species and finishes as engineered hardwood flooring.
A standard square nose replaces the tread entirely — the old surface is removed and the new tread is installed directly on the stair substrate. A cap squarenose is installed over an existing tread without removing it, which suits situations where the stair structure is in good shape and you want to avoid a full replacement.
Yes. LVP stair planks with a square nose edge are one of the most common combinations FIR installs. The profile and the flooring are selected together so the finish, color, and sheen coordinate across the floor and the staircase.
Tread depth is measured from the back of the tread (where it meets the riser above) to the front edge of the overhang. FIR measures each step during the estimate to ensure the tread depth is correct for the stair layout and building code requirements in your area.
On its own, a standard square nose tread does not wrap around an open side. For open-concept staircases, FIR installs return treads — a separate profile that wraps and finishes the exposed side of the stair. See the Return Treads page for details.
