A handrail is one of the few things in the home that really has to work when something goes wrong. If someone slips and grabs it, it is the fixing – not the profile itself – that decides whether it holds.
That is why a secure installation does not begin with the height, the appearance of the brackets, or the material of the handrail. It begins with finding a load-bearing substrate to which the brackets can actually be anchored.
The basic principle is that the handrail should be sized and installed to support someone falling against it – not just a hand resting on it.
What should a handrail be fixed to for a secure installation?
A handrail must be anchored to a structure capable of withstanding the load if someone loses their balance and grabs hold of it. On a stud wall, this may involve fixing into the studs or a structural reinforcement. In concrete and masonry, fixings suitable for the substrate are used.
It is therefore not enough for the fixing to be securely anchored in the surface layer. Brackets, fixings, and the underlying structure must all be able to withstand the load to which the handrail may be subjected.
-
Interior wall
Fix to a stud or structural reinforcement
- In a wall made of panel material, the bracket must be anchored to a load-bearing stud or a reinforcement that is securely fastened to the wall structure. On a solid wall, use fixings that are suitable for the material and the load.
-
Mounted directly on the staircase
Attach to the load-bearing structure
- If the handrail is mounted directly on the staircase, its fixings must be anchored to a load-bearing component, such as a stringer. Check that the material, construction, and fixings are suitable for the load.
-
Outdoors
Mounted on a sturdy structure
- On an exterior staircase, the handrail can be mounted to, for example, a sturdy post, a load-bearing staircase structure, or a solid wall. The mounting substrate must be able to support the load, and the hardware and fixings must be suitable for outdoor use.
What are the different ways to install a handrail on a staircase?
A handrail can normally be wall-mounted, post-mounted, or mounted on top of an existing balustrade. Which option is best depends primarily on what is located next to the staircase and what load-bearing substrate is available for anchoring.
When you compare different stair handrails, the fixing method is therefore just as important as the profile and material of the handrail.
| Installation | Fits | Things to Keep in Mind |
|---|---|---|
| Wall-mounted | Staircase with a wall along one side | The brackets must be anchored to load-bearing studs, a structural reinforcement, or a solid wall material using appropriate fixings. |
| Post-mounted | Staircase with no suitable wall for fixing a handrail | Posts must be stable and securely anchored in a structure capable of supporting the load. |
| On top of the balustrade | Staircase that already has a suitable balustrade | The top rail must have a grippable profile and be positioned and secured so that it functions as a handrail. |
Does the staircase already have a balustrade?
In such cases, a separate handrail is not always necessary. In certain balustrade designs, the top rail can also serve as a handrail, provided it has a shape that allows for a grip and is positioned and secured for that purpose. A top rail that merely terminates the balustrade does not automatically serve the same function.
How high should a handrail be installed, and what should the distance be between the brackets?
Around 90 centimetres, measured from the front edge of the steps, is a common starting point when planning the height of the handrail. A bracket spacing of around 80–100 centimetres can work for some handrails, but the spacing needs to be adapted to the profile, brackets and substrate.
When planning a handrail on a staircase, you also need to consider the staircase’s slope and how the handrail should be gripped. Use the dimensions as a planning guide and follow the product’s assembly instructions when determining the final placement.
Measure from the front edge of the step
Measure the height vertically from the front edge of the step to the handrail’s grip surface. Check the measurement on several steps to ensure that the handrail follows the staircase’s slope. Do not base your measurement solely on the floor level at the bottom of the staircase.
Avoid stretches with too much open space
The distance between the brackets affects how much the handrail can bend under load. A greater distance may require a stiffer profile or additional mounting points. Therefore, check which distance is recommended for your specific handrail and your brackets.
Is a handrail needed on both sides of a staircase?
A handrail on both sides allows users to hold on with either hand and can make the staircase easier to use. This is particularly valuable on wider staircases, where many people are moving about or where extra support is needed.
On a narrower staircase, a handrail on one side can be a practical solution. What matters is how the stairs are used, how easy the handrail is to reach and whether it gives a continuous, secure grip.
Handrail on one side
This could be an option for a narrower staircase where the handrail is easy to reach. It needs a shape that is comfortable to grip, secure anchoring and a profile that can be followed naturally along the staircase.
Handrails on both sides
Allows you to choose which hand to use for support and makes it easier to get a good grip both going up and down the stairs. This can be particularly useful on wide or heavily trafficked staircases.
Consider the staircase's intended use
Assess the need for support, the width of the stairs, and how handrails can be positioned. Whether you choose one or two, they need to be easy to grip, properly positioned, and securely anchored.
How do you choose handrails for an outdoor staircase?
Select materials based on how harsh the environment is and secure the handrail to a stable, load-bearing substrate. In environments with high levels of salt and moisture, corrosion resistance is particularly important. Therefore, make sure that the handrail, fittings, and fixings are suitable for the location.
-
Coast and salt
Marine-grade stainless steel, AISI 316
- A corrosion-resistant alternative that is well-suited for environments with salt and moisture. Even marine-grade stainless steel needs to be cleaned and maintained to preserve its surface.
-
Normal outdoor environment
Painted aluminium
- A lightweight and low-maintenance material suitable for many outdoor environments. Make sure that the finish, hardware, and fixings are designed for the environment where the handrail will be installed.
An exterior staircase can move
The staircase and the house may move at different rates, for example, due to settlement or temperature changes. In areas where the ground freezes, frost heave can also affect the position of the staircase, depending on how it is founded.
If the handrail is rigidly attached to both the staircase and the building wall, such movements can place stress on fixings. Therefore, plan the installation with consideration for how the structures are anchored and whether they can move independently of one another.
How do you install a handrail on a staircase?
Start by determining the mounting method and locating the load-bearing substrate. Then check the height, the placement of the brackets, and the appropriate fixings before drilling and installing the handrail. Always follow the product’s assembly instructions.
Check these points before the handrail installation is complete
-
Determine the mounting method
Choose whether to mount the handrail on a wall, posts, or on top of an existing balustrade. Make sure the selected solution is suitable for the handrail's intended use.
-
Locate the load-bearing substrate
Determine where studs, stringers, structural reinforcements, or other suitable load-bearing materials are located. Select fixings that are designed for the substrate and the load.
-
Stretch a string at the desired height
Mark a line between the top and bottom of the stairs and make sure it follows the slope. The string will help you determine the placement before you drill.
-
Measure from the front edge of the step
Check the height of the handrail vertically from the front edge of the step to the grip surface. Measure at several points to ensure that the placement follows the slope of the stairs and provides a natural grip.
-
Position the brackets at the correct distance
A bracket spacing of around 80–100 centimetres can be a practical starting point for some handrails. The final spacing must, however, be adapted to the stiffness of the profile, the brackets and the load-bearing capacity of the substrate. Always follow the product’s installation instructions.
-
Pre-drill if necessary
When installing in timber, pre-drilling can reduce the risk of cracks. Adjust the drill bit diameter and drilling depth according to the fixing and the manufacturer’s instructions. Other materials require drilling and fixing that are adapted to the substrate.
-
Finish the ends and check the installation
Install an end cap or other suitable closure so that there are no sharp edges or protruding parts remaining. Then check that the handrail is securely fastened, that all brackets are properly installed, and that the handrail is functional along the entire length of the staircase.
First, ensure the fixings are secure and correctly positioned. Drill and install once the height, angle, fixings, and bracket positions have been checked. Finish by checking that the handrail is securely fastened.
Not sure what kind of mounting your staircase needs?
Send a photo of the staircase and tell us what the wall or the supporting substrate is made of, and customer service will help you review the requirements for fixing.
What do you need to know when installing a handrail on a staircase?
The most common questions concern the height of the handrail, where to take the measurement, the distance between the mounting points, fixing in the wall, and which material is suitable for outdoor use. Here are brief answers to the questions that often need to be clarified before installation.
How high should the handrail be on a staircase?
About 90 cm, measured vertically from the front edge of the step to the handrail’s grip surface, is a common starting point. Adjust the height to the staircase’s design and how the handrail will be used.
Where do I measure the height of the handrail?
Measure vertically from the front edge of the step to the handrail’s grip surface. Check on several steps to ensure that the handrail follows the slope of the staircase.
How far apart should the handrail brackets be?
Approximately 80–100 cm may serve as a starting point for some handrails. The correct distance depends on the profile’s stiffness, the brackets, the substrate, and the product’s assembly instructions.
Can I install a handrail on a plasterboard wall?
No, not just in the plasterboard. Attach the brackets to load-bearing studs or a structural reinforcement that is securely anchored to the wall structure.
Is a handrail needed on both sides of a staircase?
It depends on the staircase's design and intended use. Two handrails provide support from both sides, while a handrail on one side can be a practical solution for a narrower staircase.
Which material suits an outdoor handrail?
Marine-grade stainless steel AISI 316 is a corrosion-resistant option for environments exposed to salt. Painted aluminium is suitable for many other outdoor environments. Fittings and fixings must also be suited to the location.
Do I need a separate handrail if the staircase already has a balustrade?
Not always. A graspable top rail can serve as a handrail if it is correctly positioned and secured for that purpose. A top rail does not automatically fulfil the same function.
