Key Features

  • Starting Step
  • Bowed Front
  • Rounded End(s)
  • Stain-Grade
  • Customizable

Rounded End

Each side of the 8060 Bowed Starting Step that does not attach to a wall requires a decorative Rounded End to accommodate a newel.There are three configurations available: Left, Right, and Double. NOTE: If both sides of the stair treads fit against a wall, you do not need this style of starting step.

To determine if a Left or Right Rounded End is required, stand at the bottom of the stairway and look up. If the right side is exposed, then you need a Right Rounded End. If the left side is exposed, then you need a Left Rounded End.

Double Rounded End starting steps are needed when both sides of the starting step are exposed. This style requires a special measurement called the “throat cut”, which you will need to provide when you place your order. To find the throat cut, measure the length between the inside of the Left and Right Rounded End. Each Rounded End adds 14 ⅜” per side.

Additional Style Options

  • Distressed Detailing
  • Hand Scraped Textures
  • Paint Grade Risers

Note, wood products may have varying amounts of staves due to the varying thicknesses of lumber that comes in each bunk and the width of the product.

Clear Finish & Stain Information

StairSupplies™ offers several premium stain and finish options for our products, depending on the product’s use. For Starting Steps, we offer both clear finishes and stains. Select a clear finish if you want to draw out the natural beauty and colors of the wood. If you prefer deeper, richer tones, our custom-mixed stains are the ideal choice for your Starting Steps.

All tread materials and products that are used underfoot are finished with a Conversion Varnish. Strong and resilient, this varnish is standard in the hardwood flooring industry. Our team of experts apply this specialty product onto each stair tread using a spray applicator for even, flawless coverage to protect your treads against heavy wear and tear.

Wood Grain & Color Variation

At StairSupplies™ we believe that natural wood colors and visual textures add character to our products. With that in mind, we strive to match the grain and color of all of our wood products as closely as possible. However, due to the natural variation of wood products, there may be instances in which a perfect grain and color match is not possible. By ordering from StairSupplies™ , you acknowledge that you are receiving a uniquely crafted product and there may be some variation in the grain and color of your wood products.

    Is a bowed starting tread at the bottom of a straight staircase allowed by international building code?

    Hi Frank,
    Unfortunately I don’t know about international code, you’d want to check with your local building inspector to find out for sure. Please let us know if you have any other questions.

    I have a custom bowed starting step (double returns) with carpet on it. I am replacing with wood. What is the radius of the returns for a 60 inch wide starting step. Also, Do you make custom starting step- bowed with double returns. I can send picture with dimensions.

    Hi Dinakara,
    We definitely do custom! And if you’re trying to match a specific starting step I’d recommend going that direction.
    Please let us know if you have any other questions.

    what’s the dept in the center ? 11 or 14 ?

    6 years 10 months ago

    Hi Chris,

    The radius of the starting step varies depending on the size that you order and the number of returns. The sides will be approximately 11 1/4″. In most cases, the center will be around 14″. If you need measurements for a specific size of this starting step, please let us know the width you desire, and we can provide the measurements.

    Can you provide the detailed measurements for the 60″ starting step? I want to have several bowed treads prior to the starting step. Can Stairsupplies create bowed treads and risers that match the curve of the starting step?

    Hello Tina,

    We would be able to produce bowed treads and risers for your project that would match the starting step. If you email [email protected] with more details about your project, we will be able to provide you with more detailed measurements for the 60″ starting step and design the bowed treads to meet your needs. Thanks!

    Looking at a left-hand bowed starting step. Is the tread “order” width the throat width or total width (includes left return). Also, what is length of the left return (throat cut to outer edge)…and is the bull-nose tread sit std 1.5″ proud of riser?

    6 years 1 month ago

    Hi Mark,

    The measurement that you designate for your 8060 Bowed Starting Step indicates the width of the throat cut. The return on a standard 8060 Bowed Starting Step measures 14-3/8″ from the the widest point of the bowed end to the edge of the throat cut. These measurements can be found in the Specifications tab on this product page. If you require any additional information that you don’t see listed under the Specifications tab, please give our team a call at 1 (866) 226-6536 – we would be happy to assist you.
