Are your basement stairs looking worse for wear? Do you need to build exterior stairs to your front door? Or, maybe you have an old staircase that needs a new, modern look to match the rest of your home. Whatever the reason, you’re probably wondering, "How much does it cost to remodel stairs?"

We wish that question were straightforward, but sadly it’s not. The cost of stair installation varies significantly because it is dependent on the material and construction type.

To help answer the question, "How much does it cost?" we will discuss the approximate costs of different parts of your new staircase and the cost of the entire staircase depending on its style.

The Different Parts of Stairs & Their Cost

To help get to the bottom of the cost of your new staircase, we disassemble stairs into their main parts, discussing the approximate cost of each piece. Keep reading below to estimate your interior staircase installation cost.

Steps

The steps on your staircase are made up of two components: tread and risers.

Tread

Stair tread is the upper horizontal area where you put your feet when ascending or descending a staircase. There are many options for your tread including wood, metal, and concrete. Wooden steps are the most affordable per square foot.

• Concrete stairs: A concrete staircase will cost approximately $300 per step.
• Wood stairs: The cost of wooden stairs depends on the type of wood you select. For example, red oak costs approximately $60-$120 per step, whereas maple costs $60-$90 per step. The wood stain can also factor into the cost.
• Metal staircases: Stainless steel staircases run at approximately $200 per step.
• Marble staircases: Custom stairs made out of marble typically cost $100 to $120 per step.

Risers

Risers are vertical boards or sections of the step. They help connect and support successive treads.

Most interior staircases use the same material for tread and risers. However, floating stairs will not have any risers whatsoever.

Nosing

Nosing is the protruding part beyond the riser. It’s typically rounded to give an aesthetically pleasing appearance to the treads. Nosing can also make most interior stairs easier to use.

Nosing will cost approximately $3-$5 per foot. Make sure to add the cost of nosing to your staircase cost unless you are making a glass staircase or a stone staircase.

Stair Railings

Staircase railings provide extra security and safety with each step. You can hold onto the railing as you descend the staircase, holding on for more balance. Whether they are railings or wall-mounted handrails, they help decrease the risk of falls and can make your home a safer place.

There are various types of railings that you can choose from for your staircase remodel. Here are some examples and what you can expect to pay for them:

• Glass railing: Glass is an aesthetically pleasing choice for your railing, but it will cost quite a pretty penny. The average glass staircase cost is $130 per linear foot.
• Wood railing: Wood railing is the more affordable option for your renovation. Wood costs approximately $10-$30 per linear foot.
• Wrought iron stair railing: Wrought iron is a timeless choice for your staircase railing. It will cost approximately $100-$350 to install an iron railing on your new staircase.

Costs For Custom Staircase Designs

There are many staircase styles to choose from. We have included the approximate installation costs of various main staircases without labor costs. Other factors may affect these costs, such as whether the contractors remodel the old stairs or replace the staircase.

• Straight staircases: A straight staircase is one of the most common designs for interior stairs. It will cost you approximately $700-$1,500.
• Floating staircases: If you are looking to make a statement with floating stairs, you can expect to have to pay for it. The approximate floating staircase cost is $2,000-$5,000.
• Spiraling staircases: If you want to make a statement with a grand spiral staircase, you will have to be ready to open your wallet. A spiral staircase can cost approximately $1,600-$4,000.
• L-shaped stairs: Installing stairs that are L-shaped will cost approximately $900-$1,800.
• Curved staircases: A arched or U-shaped staircase will be a grand main staircase in your home, leading elegantly from one level to the next. U-shaped stairs will cost approximately $1,200-$2,000.
• Winder stairs: These stairs curve around the walls surrounding the staircase and are narrower on one side than the other. The purpose of these stairs is to fit them in a narrow room. You can expect to pay approximately $2,000-$5,000 for a winder staircase.
