Definition

What is a round-nose treads stair?

A round-nose (bullnose) tread has a rounded leading edge on each step rather than a hard corner. The softer profile reads traditional and colonial, pairs well with carpet runners, and is available in both stain-grade and paint-grade.

How it compares

How does a turn-style stair save space?

The trade-off across the turning configurations is footprint versus comfort. A landing is easiest to walk; a winder is the most compact. Here is where each one sits.

Round-nose treads FAQs

Common questions about round-nose treads.

  • Q: Round-nose vs square-nose treads — which should I choose?

    Round-nose (bullnose) reads traditional and softens the look, and it's the safer feel underfoot for a carpet-runner stair. Square-nose reads modern and transitional. Match the tread nose to the rest of your trim vocabulary — bullnose with colonial, square with contemporary.

  • Q: Does a bullnose tread change the code overhang?

    Code sets a tread nosing projection (typically 3/4 to 1-1/4 inches) regardless of profile. A round-nose meets it with a rounded edge; a square-nose with a chamfer. We build the nosing to your adopted code either way.
