A Stylish DIY Stair Handrail For Your Home

Then, spin your TOP railing over 180 degrees so you’re looking at the bottom of the top railing; drill two more pocket holes into each side. 
Use a square to mark precisely where the baseboard needs to be cut.
Because the wall that we’re connecting to has baseboards, we’ll have to cut that out in order to fit our handrail flush against the wall itself. 

The Step-by-Step to Build a DIY Indoor Stair Handrail

Drill a hole for where you’ll place the bolt to hold the stair handrails in place.

Fill with wood filler, let it dry, then sand it smooth.
Does your stair handrail crave a new look? If so, you can easily do that yourself with some basic tools.

Materials needed for the black stair handrail project:

• Measuring tape 
• Paper and pencil
• Drill and drill bits
• Wood clamp
• Milter saw
• Sandpaper 
• Electric sander
• Dremel
• Hammer
• Screwdriver 
• Screws
• Brad nails 
• Baluster Connectors 
• Kreg jig HD

Part 1: Measure your stair handrail height & plan layout

Use a miter saw to cut your 4×4 precisely. 

These drilled sides will be the sides that face the stairs and the room; the two non-drilled sides will face the railing and wall (or whatever else lies along that handrail axis at your house). 
Important Note: 
Black pipe rails (aka balusters or spindles) are both straightforward and chic.
Take one of your vertical posts and, on the bottom end of the side that will be facing you when the handrail is installed (opposite the stairs), center and clamp the drill guide in place.



Fill the tops of your pocket holes with wood filler, because these will be visible above your 1×3 trim board. 

Part 2: Use miter saw to begin cutting railings & measure posts

Install the timber screws, taking care with the first one especially that the handrail is precisely in place and level everywhere.
Determine the level/height at which you want your timber screws to be installed, then pre-drill holes into your 4×4 at that/those positions. 
Happy creating!
Use a rubber mallet to gently tap the top railing down so it is flush with the top of your vertical posts.
This will facilitate perfection in vertically aligned rails/spindles.




These stair handrail ideas are just a few to kickstart your own process; whether it’s to make it yourself as laid out above or help you find stair handrail kits instead.

Part 3: Use the Kreg Jig to create pocket holes in your stair handrail posts

Choose the best 4×4 for the job of your top and bottom railings. 

With the handrail fitting into its perfect footprint, it’s now time to mount it.


Time to insert the baluster connectors.


Use 6” timber screws to attach the bottom part of the vertical post to the wall.

Attach the top of the vertical post to the wall via the two top-edge pocket holes.
Note: For this example 4x4s for the two side posts, 4x4s for the top and bottom rails attaching between the vertical posts, and a 1×6 as the top surface of the railing.
Same for the bottom of the bottom railing. The sides and the top of the bottom railing are going to be most visible, so choose the best 4×4 faces for these positions.

Measure your posts. (You’ll want to work backward on this.)

At this point, you should have two identical-length top and bottom railings and two identical-length side posts, all out of 4×4.

So, toward the “wall” side on the top of this vertical post, I will drill two pocket holes.
Your pocket hole wood filler sands easily and will look something like this.
Stain the wood with your preference or use a clear finish coat.
Take note if your wood filler needs hand sanding as opposed to high-speed orbital sander.
Use 2-1/2” HD pocket screws to attach the railing to the post.

You can see here the overhang of the 1×6 cap board. This adds some substance to the railing, as well as hides the holes and flaws underneath. It does have a bit of craftsman flavor, too.

The length of the pipe spindles/rails (standard are 26” and 32” rails) plus the height of your top and bottom railings PLUS the 1×6 cap piece must be to code. 
Pro Tip: 
The difference between a handrail and a stair rail is that one is optional and the other mandatory. A handrail is primarily support for elders, who may need additional support as they move about an area, be it a stairway or bathroom. A stair handrail is a necessary support along a staircase to prevent anyone from falling, providing balance.

So, the posts themselves are 39” (the height of everything except the 1×6 cap).
The trim piece will hit in the middle of these screws’ heads, you have to counter-sink them with a 1/2″ drill bit.

Part 4: Prepare the bottom and top railings

Sand this board until it’s perfectly smooth. Run a bead of wood glue along the top of your vertical posts and top railing.
Use a medium grit (120) sandpaper, and sand everything. Don’t forget the corners.
Place the drill guide accordingly.

Adjust if necessary.
You’ll need the Kreg HD jig for the 4×4 posts.

On both ends of the top of the TOP railing, drill two pocket holes. 
First, adjust the stop collar on your HD drill bit so it is 4-3/4” away from the shoulder of the bit. 
To begin installation, attach the bottom railing to the vertical posts via the two pocket holes on the bottom side of the bottom railing.
If you’re mounting the handrail to a wall, you will drill pocket holes into the top end of ONLY the post that mounts to that wall. 

Predrill through the vertical post into the top part of the bottom railing, taking care not to aim too high, which will expose the screw.



In a place that will be covered or hidden, write the piece’s orientation to your space so that you can keep your favorite lumber faces exposed and front-and-center (and the worst faces tucked away).
This post is now ready to be installed on the wall via the top, and attached to the floor (on the two sides 90-degrees from this wall-mount side) via pocket screws on the bottom sides.

Part 5: Sand all your wood

When the railing is flush with the top of your vertical posts, use 2-1/2” HD pocket screws to attach the end of the railing to the wall-mounted vertical post via the top pocket holes.
A handrail is also called a banister
Pro Tip: Place your 4x4s on a slightly raised surface to allow maximum air flow and circulation while they dry.

Part 6: Apply wood filler

Position the handrail where it’s going to go. 



Outline your plan.
Because screwing into pocket holes can sometimes (not always, but sometimes) move the entire piece a fraction of an inch, we wanted the floating end to be secured to the floor before attaching the pocket screws. So, we centered and marked where we wanted four sets of timber screws along/through the bottom railing.
Note: The most important thing with screwing these connectors in place is, aside from their actual precise placement along the board itself, to screw them in exactly straight up-and-down.

Part 7: Once wood filler sets, sand again

While we showed you how to make an interior stair handrail, you can also apply this technique to exterior stair handrails (like your pool deck stair handrail!).


Mark these rail points in the same direction on your top railing as on your bottom railing. 

Part 8: Place the Baluster Connectors

The post A Stylish DIY Stair Handrail For Your Home appeared first on Homedit.
A file or chisel and hammer should remove the baseboard chunk pretty easily.

In this project example, it exceeded code, with a 39-3/4” handrail height, floor to top. (32” rails + 3-1/2” nominal height of 4×4 top railing + 3-1/2” bottom railing + 3/4″ nominal height of 1×6 cap.) 

Part 9: Begin installation of railings

Finally, remove the bottom railing.
Start by removing the existing spindles.
Center, then lay your 1×6 on top of your modern stair handrail. Clamp into place.
For reference: 
Here is one set of timber screws.

Use 2-1/2” HD pocket screws now to attach the bottom of the now-wall-mounted vertical post to the floor, two screws on each side through the pocket holes.
Measure, mark, and cut your posts. 



Don’t worry if it doesn’t side exactly square at this unconnected point.

Part 10: Position the stair handrail, adjust as needed

You now need to prepare the top and bottom railings. 

Part 11: Remove existing stair handrail

Time to remove the existing handrail.

We hope you enjoyed this DIY stair handrail and look forward to completing it in your home!

Smooth the wood filler, but don’t stress about getting it perfect at this point. You’ll sand it down after it dries thoroughly.
Use a multi-function (Dremel) tool to cut it out.
In this example, one vertical post mounts to a wall, and the other is a freestanding post in the center of nothing, at the top of the stairs. 

Part 12: Installing stair handrail

Then, remove the top railing.


While a bit more complicated than a traditional home DIY project, you can install stair handrails yourself over a weekend. All it takes to install stair handrails is some great wood, cutting equipment, screws, and patience!

This DIY stair handrail tutorial will take you through the step-by-step process of removing your old stair railing, building a new one, and installing as well as securing it.

Use a reciprocating saw to carefully cut the post at the level of the sub-floor (or whatever level the rest of your handrail will be sitting on), then flatten and smooth the surface as needed with a file and hammer.

Pro Tip (Optional): Dry-fit the rails/spindles/balusters onto your connectors, then place your top railing onto them. 

Part 13: Flatten and smooth surface

For reference: This example shows rails spaced precisely 4” on center, which means the actual space between the rails is less than 3-1/2” because the rails themselves are 3/4″ in diameter.

These holes are for attaching the railing to the vertical posts. 

Replace all your spindles and the top railing. 

Part 14: Install timber screws

Remove the top railing and several (if not all) of your spindles.
Let them dry, then sand with 220-grit sandpaper until they are smooth and the wood filler perimeter disappears.
Let it dry. Congratulations! Your new contemporary-industrial handrail looks gorgeous.
At this point, you should have four pocket holes drilled into the two opposite sides of one vertical post. 
Tighten the stop collar into place.
This end should be secure with timber screws in place.
Wipe away the dust.



Pro Tip: Be sure to check for framing stud presence first, or the timber screws won’t be much help.
Use a miter saw to cut a 45-degree angle that leads OUT AND AWAY from the measured distance.
When you’re drilling into 4x4s, you don’t have to adjust the drill guide to get two perfectly spaced and centered pocket holes. 
Use 1-1/4” or 1-1/2” brad nails to nail cap board into place.
Apply the stain to the wood stair handrail.

Part 15: Add support to the ‘floating’ post

Double checking the flush and level lines. 
On only the bottom side of your BOTTOM railing, drill two pocket holes on each end. DO NOT DRILL POCKET HOLES INTO THE TOP SIDE OF YOUR BOTTOM RAILING, as these will be totally visible.
Predrill these holes for the 6” timber screws.
Repeat this for your bottom railing.

And repeat for the other “floating” post end, top and bottom pocket holes of the top railing into the vertical post.


Pro Tip: This is definitely a two-person job, as you’ll want to ensure level at all three dimensions before you install.
Now, use those 2-1/2” HD pocket screws and secure the floating post to the floor via the four pocket holes.

Let the wood filler dry completely. 
The side the stair handrail will be depends one where your wall falls. If you have a wall on the left, then the handrail will be on the right, and vice versa.
The bottom holes on your top railing will technically be visible, but because they’re on the bottom of the railing, you won’t actually see them. 

Use a right-angle clamp to hold the pieces in place and together, after double-checking the positioning of the vertical post.
Be sure your two left sides align and the two right sides align, and use your template moving in the same direction on each railing. 




This is how the white stair handrail looked before the DIY project was implemented.

Part 16: Secure floating posts to floor

While the choice is ultimately down to aesthetic preference, a stain will always be more durable than paint. Paint fades or chips and will require upkeep through the years.
On the facing sides of your railings (e.g., the top side of your bottom railing, and the bottom side of your top railing), use a guide to drill light holes to mark the spindle/rail placements. 

Part 17: Time for the trim

Sand your wall mounted stair rail with fine grit, then apply a second coat of stain or clear coat. 
Drill your pocket holes through the top edge.
Slide and hold the handrail in place, flush against the wall and level every other direction, then screw the timber screws into the wall.
Measure and mark the length of your top railing (minus the width of your two posts) on the 4×4. 

Repeat for the other vertical post. 
Remember that the top side of your top railing will be covered with the 1×6 piece, so you can use your worst side for the top of the top railing. 



This depends. A stair handrail can cost up to ,000 with installation on the higher end, or as low as 0. For this reason, we recommend a Home Depot stair handrail, aka, one you make yourself.
These nail holes will be visible, so you’re going to want to fill them to re-create your smooth top of your pipe stair handrail.
Nope! In fact, using complementary colors is the perfect way to give your space dimensional appeal.

Now is the time to make any obvious adjustments. 
Screw the timber screws into the vertical post all the way, so their heads fall at or below the vertical post face.

Label these accordingly.
We simply applied a few coats of matte clear Polycrylic
Your handrail cap board will be perfectly smooth and delightful after sanding. Wipe away all sanding dust.

Part 18: Add your stain to the stair handrail

Flat wall should be achieved for the post.
Apply wood filler to cracks, splits, knot holes, or any imperfections that you want to seal up on the sides of your 4x4s that will be visible.
Repeat this step on the bottom end of your other vertical post.


Take stock of all the pieces and decide which pieces will go where. 


Repeat for both sides of your handrail, then cut the top piece with two 45-degree angles to fit perfectly against them.
Next, attach the stop block to the drill guide. 


Drill into the two guide holes to create two pocket holes.

The top holes on your top railing will be covered by the 1×6 cap piece. 
Prepare all the joints that need to happen on this handrail/railing. 
Since the vertical post  is only connected to the bottom railing via two pocket screws on the bottom, you’re going to add support with two more 6” timber screws. 
Pro Tip: 
Do the same on the bottom pocket holes.
Measure, mark, and cut your 1×6 board to extend 3/4” or 1” longer than your entire top surface (vertical post end to vertical post end). 
Turn your post over, and drill two more holes on the exact opposite side of the bottom of your post. 

Conclusion:

Place the drill bit through the drill holes, and make sure that the tip of the drill bit is 3/8” away from the stop block. 
You’ll want to measure the length of your railing, from wall to the outer edge of where your post will be. 
The contrast of the black spindles of this stair railing and the blonde wood is striking. 

When the wood filler is completely dry, use a fine grit (220) sandpaper and have at it.
