How Do I Make My Stair Treads Deeper?

Ever feel like your stairs are a little too narrow for comfort?

If you’ve ever worried about slipping or tripping, you’re not alone—many homeowners feel the same.

How do I make my stair treads deeper?

You can either extend your current treads using wood attachments or fully replace them with deeper, more comfortable ones.

In this guide, you’ll learn exactly how to measure, modify, and finish your stair treads with simple, effective steps.

We’ll also cover how carpet stair treads can enhance both safety and style once your treads are deepened.

Whether you're looking for a safer staircase or a more refined look, you'll walk away with the know-how to get it done confidently.

Why Deep Stair Treads Matter  

Deep stair treads aren’t just a design choice—they’re a safety feature.

When your foot doesn’t fully land on each step, you increase the chance of slipping, especially when you're carrying something, wearing socks, or moving quickly.

Here’s what deeper treads bring to your home:

• Better safety for kids, pets, and older adults

• Comfortable walking that feels natural and less strained

• A finished look that makes your staircase a design highlight

• Noise reduction when paired with the right materials

• Increased resale value, especially in older homes with narrow steps

Most building codes recommend a tread depth of 10–11 inches, but many homeowners go deeper for added comfort.

Measuring and Planning: The First Step to Deeper Treads  

Before you pick up a tool or place an order, you need to assess your current staircase.

Measure Existing Tread Depth  

Use a tape measure to check the depth of each stair tread from the front edge to the back edge.

Write down your numbers—you’ll want consistency across every step.

If you find your treads are under 10 inches, it’s time to consider an upgrade.

Decide How Much Deeper You Need  

Think about how your household uses the stairs:

• Do you have larger feet?

• Do kids or pets run up and down frequently?

• Are your stairs steep and hard to walk comfortably?

Even adding just 1.5 to 2 inches can make a big difference in how safe and natural your stairs feel.

Option 1: Extending Your Stair Treads  

If your existing treads are in good shape, you can extend them instead of replacing them.

This approach adds a bit of depth to the front edge of each tread, usually by gluing and securing a wood extension.

Tools & Materials You'll Need  

• Wood extensions or solid boards

• Measuring tape

• Wood glue (strong bonding type)

• Screws or nails

• Clamps

• Fine-grit sandpaper

• Paint or stain

• Polyurethane finish

• A saw for cutting

• Safety gear

Step 1: Cut Your Wood Extensions  

Measure how much extra depth you want.

Cut matching wood strips to fit each stair width and desired extension depth.

Make sure the material you use is sturdy and doesn't flex under weight.

Step 2: Apply Wood Glue  

Generously apply glue to the back of each wood piece.

Press the extension firmly onto the front edge of the tread.

Use clamps to hold it in place for at least 30–60 minutes.

Step 3: Secure With Nails or Screws  

Once the glue sets, reinforce the extension with nails or screws from underneath.

Avoid visible hardware on the top surface for a clean, finished look.

Some homeowners also choose to add a small amount of glue along the side seams for added support.

This is where a common question arises: do you caulk stair treads?

If there are visible gaps where the extension meets the original tread, yes—you should caulk them.

Use paintable, flexible caulk that blends well with your finishing materials.

It helps seal the join, improves appearance, and prevents dirt from collecting in seams.

Step 4: Sand the Surface Smooth  

Blend the transition between the old tread and the extension using sandpaper.

Remove any rough spots or edges.

Wipe away dust with a clean, damp cloth.

Step 5: Stain or Paint  

Use a matching stain or paint to blend the new extension with the rest of your stair.

Apply thin coats and let each coat dry fully before adding the next.

After staining or painting, many ask: how many coats of polyurethane on stair treads is enough?

We recommend at least 2–3 coats of polyurethane for durability, especially on high-traffic stairs.

Let each coat dry fully and lightly sand between coats for a smoother finish and better grip.

Option 2: Replacing Your Stair Treads Entirely  

If your stair treads are old, damaged, or too thin to extend safely, full replacement might be the better route.

Removing Old Treads  

Use a pry bar to gently remove each tread from the stringers.

Take your time to avoid damaging the surrounding structure.

Choosing New Materials  

Here are some excellent material choices for new treads:

• Hardwood – Strong, timeless, and great for stained finishes

• Engineered wood – More affordable but still durable

• Laminate – Low-maintenance and budget-friendly

• Carpeted treads – Great for added softness and slip resistance

Make sure the new treads are wider than the old ones and cut to match your staircase.

Installing New Treads  

Apply wood glue along the stringers and secure the treads with nails or screws.

Use a level to ensure each step is flush and even.

Sand edges if necessary for a tight fit.

Finish with stain or paint, and top it off with polyurethane just like you would with extensions.

Again, apply two to three coats for a durable, long-lasting finish.

Common Mistakes to Avoid When Deepening Treads  

Even a simple DIY can go sideways if you’re not careful.

Using the Wrong Materials  

Make sure the wood you use is rated for flooring, not soft pine or anything that flexes easily.

Skipping Sanding or Finishing  

A rough tread is a safety hazard—and it looks unfinished.

Sanding and sealing are crucial steps for safety and long-term wear.

Not Accounting for Riser Height  

If you make your treads deeper but don’t adjust the risers, your stair’s rise/run ratio might feel “off.”

Always check local code guidelines for total stair dimensions.

Tips for Long-Term Maintenance  

Once your deeper stair treads are in place, take care of them like any other surface in your home.

• Clean regularly with gentle, non-abrasive cleaners

• Check caulking or glue seams yearly and reapply as needed

• Recoat with polyurethane every few years if the finish wears down

• If you’re using carpet stair treads, vacuum them regularly and spot clean spills

Steps to Success  

So, how do I make my stair treads deeper?

You do it with intention, care, and the right tools. Whether you extend your existing treads or start fresh with brand-new materials, the result is a safer, more stylish, and more comfortable staircase.
