Wood stair treads are offered in a standard 1-1/32″ finished thickness after surfacing and sanding. Extra thick hardwood stair treads for open rise staircases are available in any thickness. The most popular over sized wood tread sizes are 1-3/4″ and 2″ thick. We have produced treads as thick as 4″. Any stair tread thicker than 1-3/4″ will require face glue lamination(s) to meet the desired finished dimension.
