How To Support A Laundry Room Countertop Over A Washer And Dryer
How do you build a counter over a washer and dryer?
That is one of the challenging questions we faced when renovating the laundry
room. A countertop in the laundry room is a necessity. Whether you have a
small laundry room or a large one, you want to make ever inch count!
A countertop above the washing machine and dryer provides counter space for
folding clothes, a great place for placing detergent and other cleaning
products, a work surface when you're at the sink, and - as is the case in our
house - room to stack the folded clothes for weeks until you put them away ;).
In fact, having a countertop is a priority for our laundry room makeover and
one of the reasons we didn't opt for a top load washer and dryer.
We debated a few different options for the countertop material - a butcher block countertop, laminate, Corian, natural stone. In the end, we went with a stainless steel countertop in our laundry room and I thought I'd share the steps we took to install and support the countertop over our front load washing machine and dryer.
How To Build A Counter Over A Washer And Dryer
Determining how to install a laundry countertop is not complicated and is an easy DIY project. If you are installing your own counter over front loaders, no matter what material you use for the countertop, the supporting structure beneath will pretty much be the same.
In fact, the method I am sharing here can be used to install any kind of
floating horizontal surface. You can use it for a desk, counter, or floating
bench.
What's the best way to support a countertop across a washer and dryer?
Typically, laundry rooms have a counter over the top of the washer and dryer.
In order to support a laundry room countertop, you may need two components:
something to affix the countertop to the wall, and something to hold the
countertop above the laundry machines.
This easy method uses a combination of cleats and gables to
achieve that. The cleat provides a brace to hold the countertop up on the
wall, and the gables provides support on the side and underneath a long counter so it won't
sag.
If our washer and dryer was in a niche and had walls on three sides,
depending on the weight of the countertop, we could install the countertop
just using cleats.
In our situation, we had a sink beside the washing machine and dryer so we
used a pre-made gable (an Ikea panel from the As Is section) to support one side
of the countertop, a DIY gable hidden between the machines to provide additional
support, and cleats on the back and right side walls.
Countertop Materials for the Laundry Room
The cleat and gable method can be used to support most any kind of
countertop including butcher block countertops, laminate countertops to
natural stone.
Now depending on countertop material you choose, the first thing you need to
determine is if you need a substrate as well. Here's a few options:
- if you are using a plywood countertop, you do not need a substrate. The plywood sits on the cleats and is supported by the gable
- if you are building a countertop out of individual pine boards, you do not need a substrate. The boards span the width and are affixed directly to the cleats
- if you are using a pre-fabricated laminate countertop you purchased at Home Depot or the like, you do not need an additional substrate. The laminate (plastic) is already fused onto a substrate (either plywood, MDF or particleboard. See here for differences about the materials.)
- if you are using wood countertops like a butcher block countertop, you do not need a substrate. The butcher block sits on the cleats and is supported by the gable
- if you are using a natural stone or engineered stone solid surface countertops (e.g. Corian or quartz countertop), you may or may not need a substrate. The stone may be strong enough on its own to span the area above your washer and dryer. Consult with your stone fabricator to see what is needed
- if you are making your own countertop and covering it with laminate or stainless steel, then yes, you need to build the substrate first.
Floating Countertop Support
In addition to using this method for a counter over a washer and dryer, you
can also use cleats and gables for:
- installing floating shelves in a closet
- installing a floating countertop in a three sided nook
- installing a floating desktop between cabinets like this
- installing a floating bench
Generally, you can use a combination cleats and gables anywhere you want to
install a horizontal surface. Installing and supporting a floating
countertop of any kind is not difficult. Here's how we did it.
How To Install A Countertop Over A Washer And Dryer:
1. Draw a Level Line
First step to installing a counter over a washer and dryer is to draw a level
line to indicate the underside of the countertop. If you want to be able to
move your washing machines in and out, you'll want to ensure you have enough
room so don't have the countertop touching the tops of the machines. We had
about a 3" gap above our machines.
2. Install a cleat on the wall
Under this line, install a cleat.
A cleat is a strip of material to which the countertop will be attached and
which provides horizontal support.
Sean used a scrap 3/4" piece of plywood cut into 2" strips to create the
cleats. He affixed the cleats with construction adhesive (you could also use
wood glue) and used a stud finder and screwed the cleats into the wall studs.
Since we were using an end panel on the left side of the washer, we only
needed to install cleats along the back and right wall.
Cleats provide extra support whenever you want something to appear "floating".
Here's an example where we used cleats to
mount an IKEA bookcase to the wall.
You'll notice that the right side cleat is mitred at the end and is set back
from the face of the countertop. By doing this, the cleat won't be visible
once the countertop is installed. You could even paint the cleat your wall
colour to make it less visible.

3. Support the countertop with a gable
If your countertop spans a wide area, or if one end of your countertop is not against a wall, you'll also need to install gables. For our laundry room, we used two gables:- one gable to the left of the washing machines (between the sink cabinet and the washer). We used a panel from the IKEA As Is section and cut it to size
- one centre gable in between the washing machines (to provide additional support underneath the countertop). We made this gable out of plywood.
Gables are also known as cabinet end panels. End panels can be used for
decorative purposes (for example, to hide the unfinished sides of a kitchen
cabinet) or for structural purposes (to create a niche or box around your
refrigerator). See this post for tips on building DIY gables/cabinet end panels.
Countertop Support Gable:
The photo below shows the centre gable we created out of plywood. This gable
is placed vertically between the washer and dryer set and is positioned with
the horizontal piece running from the front of the machines to the back
wall, with the vertical pieces against the back cleat.
Ensure that the height of the gable is level with the top of the cleat and that the depth of the gable is shorter than the depth of your countertop. Again, you'll want to make your gable less deep than your counter so it isn't visible once fully installed. Because this gable is not visible once the counter and machines are installed, it does not need to be finished or painted.

Because this gable is not visible once the counter and machines are installed, it does not need to be finished or painted.
The top short vertical piece will screw into the cleat. For the bottom
vertical piece, you will first need to screw a spacer piece (the same
thickness as the cleat) at the base of your wall, and screw into that. The
long horizontal piece will be screwed into the underside of the
countertop.
Once the countertop has been attached to the cleat and gables, slide the washer and dryer back in place. Here's our plywood countertops installed!

There's more to come in this room, hence the missing paint in the corners. But we'll leave those surprises for another post.
How to build a countertop base or substrate:
If you are building your own countertop, say out of plywood, here is an
example of how you can structure it.
What you are looking at is the underside of the countertop. This
countertop is built out of a sheet of 3/4" plywood with additional
3/4"strips around the perimeter and middle. The middle strip is what the
centre gable will screw upwards into.
4. Affix the countertop to the cleats and gable
Use a combination of L-brackets, construction adhesive, and screws to affix the countertop and gable. This task is best done with two people.First, if you have a side gable, put it in place. If it is beside a cabinet, attach it to the cabinet with cabinet screws from inside the cabinet.
Next, put your countertop in place resting it on the cleat and side gable. Have one
person hold the countertop while the other person attaches L-brackets
around the perimeter of the countertop. Screw one side of the L into the
countertop and the other into the cleat.
Next, slide the centre gable in place. Use L-brackets
along the top of the gable with one side screwed into the underside of
the countertop (along the middle horizontal piece) and the other into the
gable.
Once the countertop has been attached to the cleat and gables, slide the washer and dryer back in place. Here's our plywood countertops installed!
You might be wondering where our water shut-off valves are. We've brought them into the hidden storage room that sits behind this laundry room. See the washing machine supply lines in this post.
If we had sanded and sealed the plywood, we could call this project
done. A plywood countertop is affordable but not exactly the most
durable or water resistant in a laundry room. So, we took that plywood
substrate to a metal fabricator and had it clad with stainless steel.
Stainless Steel Countertop
The more we thought about it, the more stainless steel countertops in
the laundry room made sense. They are resistant to water and heat
damage, hygienic, and would create a nice integrated look with the
stainless steel sink. Plus, they are reflective and nicely bounce the
light around this windowless laundry room.
Stainless steel can be expensive but we called around and found a local
fabricator with an amazing price and very quick turnaround. Because we
built the substrate ourselves and did the install too, we saved on the
cost.
We've already done tons of loads of laundry and I have to say it feels
great to fold clothes and have this counter over the washer and dryer.
There is enough space between the counter and the upper cabinets. This
is quickly becoming one of our favourite rooms in the house :)

There's more to come in this room, hence the missing paint in the corners. But we'll leave those surprises for another post.

UPDATE: We used the cleat & gable method once again for the countertop in our latest laundry room. However, this time, instead of using a pre-made panel as a gable, we made our own gable.
