Adding outdoor seating to your patio or backyard can be expensive, but you can save money by building your own DIY patio bench. With some basic tools and materials, you can create a sturdy, comfortable bench perfect for relaxing outdoors. This comprehensive guide will walk you through the entire process of constructing your own patio bench, from planning and design to finishing. Follow along to learn how to make a DIY patio bench that looks great and withstands the elements.
Planning Your DIY Patio Bench
Before you start building, take some time to plan out your patio bench project. Consider the following factors:
Desired Size
Think about how much seating space you need. A 4-6 foot bench is comfortable for 2-3 people. For additional seating, make your bench longer or build two benches.
Material Choice
Patio benches are often made of wood, metal, plastic, or a combination. Wood is attractive and durable, but requires more maintenance. Metal and plastic need less upkeep. Choose materials that fit your style, skill level, and budget.
Bench Design
Basic bench designs feature straight legs and a flat seat. You can also incorporate back rests, contoured seats, decorative details, and more. Draw sketches to visualize the look you want.
Placement
Survey your outdoor space to find the perfect spot for relaxing on your new bench. Look for level ground in a shaded area. Face the bench towards points of interest.
Build vs Buy
While building your own bench takes more time upfront, it often costs less than purchasing a ready-made bench. And you can customize your design!
Selecting Materials for a DIY Patio Bench
Once you’ve settled on the size, style, and location of your patio bench, it’s time to gather materials. Here are some of the main components you’ll need:
Wood
For the seat, legs, and supports, opt for cedar, redwood, or pressure-treated lumber. These woods stand up well to outdoor conditions. Choose 2x4s and 2x6s for the frame and 1x4s or 1x6s for slats.
Hardware
Purchase exterior-grade screws, nails, bolts, and metal braces specifically for outdoor use. Galvanized or stainless steel hardware lasts longer outside.
Tools
You’ll need basic tools – a saw, drill, sandpaper, carpenter’s square, level, tape measure, clamps, and safety gear. Many home DIYers already own these.
Concrete
For permanent placement, set the legs in concrete for stability. Quickrete or Quikrete work well.
Paint/Stain
Optional protective finishes like exterior wood stain add color and weatherproofing. Or use paint if you want a crisp, solid color.
Fasteners
In addition to screws and nails, construct with weather-resistant wood glue and exterior-rated construction adhesive.
How to Build the Frame for a Patio Bench
The frame supports the main structure of your DIY patio bench. Follow these instructions to construct a sturdy frame built to last:
Cut the Legs
Cut four equal length 2x4s for the legs using a power miter saw. Cut the legs a few inches longer than your desired bench height to allow for setting them in the ground or concrete.
Cut the Side Supports
Measure the total width of your bench seat. Cut two 2x4s to this length – these will be the side supports.
Assemble the Frame
Arrange the legs and side supports on a flat surface. Position the legs at each corner, with a side support spanning each pair of legs along the width.
Secure with Exterior Screws
Drill pilot holes and use 3-inch exterior screws to attach the side supports to the upper side of the legs so the frames lies flat. Double check the frame is square using a carpenter’s square.
Add Center Supports
For benches over 5 feet long, cut one or two 2x4s as cross supports in the middle of the frame. Attach with more screws through the side boards into the ends of the center supports.
Your bench frame is complete! Next you’ll add the seat slats.
Attaching the Seat Slats to Your Patio Bench
The seat slats provide the flat surface for sitting on your DIY patio bench. Follow this easy process:
Cut the Seat Slats
Use 1×4 or 1×6 boards for the slats. Measure and cut them to the exact width between the two side supports.
Space Slats Evenly
Lay the cut slats across the frame with small, equal gaps between each board. Even 1/4 to 1/2 inch gaps are fine.
Secure the Slats
Drill pilot holes down through the slats into the side supports. Drive in exterior screws to attach each slat securely.
Add Front and Side Edging
For a finished look, cut edging boards and attach them around the front and sides to cover the slab ends.
After attaching the seat slats, your bench is ready for sanding, finishing, and installing!
Sand and Finish Your DIY Garden Bench
Proper finishing protects your wood bench from weathering and gives it an attractive, polished look:
Sand Thoroughly
Use coarse 80 grit sandpaper to smooth any rough spots on the wood. Then switch to fine 120 grit to sand the entire bench.
Wipe Away Dust
With a dry cloth, remove all sawdust and debris after sanding so the finish adheres properly.
Apply Exterior Stain
For rich color that shows off the wood grain, use several coats of exterior stain in your desired hue. Let each coat fully dry before adding the next.
Or Use Exterior Paint
For solid, opaque coverage, apply several coats of exterior grade acrylic latex paint. Allow proper drying time between coats.
Consider a Sealer
Adding coats of water-repellent sealer or a marine varnish provides extra protection from moisture damage.
Let your finish fully cure before placing your bench outside. Apply touch up coats annually to maintain its luster.
Setting Your Patio Bench in Place
When your DIY patio bench is complete, it’s time to install it for enjoying those sunny days relaxing in your yard. Here are two options:
In-Ground Supports
Dig holes for each leg, ensuring they reach below the frost line in your climate. Place the legs in the holes and backfill with concrete to anchor the bench in place.
Surface Mounting
For movable seating, attach the legs to an existing patio or deck using strong metal brackets and bolts into the legs. Add self-adhesive felt pads under the legs to prevent sliding and scratches.
Carefully check that your bench sits level before securing the legs in position. Place your new patio bench in a shaded area and accessorize with comfy cushions!
DIY Patio Bench Ideas
Customizing your patio bench is simple. Get creative with these easy upgrade ideas:
- Add a contoured back rest for superior comfort. Attach curved 2x4s or 1x4s between the legs flush with the rear of the seat.
- Decorate the center back rest slat with mosaic tiles, carvings, metal medallions, monograms, or other personalization.
- Incorporate built-in planter boxes under the seat to hold flowers, herbs, or trailing vines.
- Opt for angled legs for a more contemporary style bench. Miter cut the legs and Experiment with different leg heights.
- Attach an overhead arbor above the bench with wood slats for a shaded resting spot. Grow climbing vines on the arbor.
- Stain or paint the bench bold, contrasting colors for added flair. Try combining colors on the legs, supports, seat, and back.
- Add removable cushions covered in weather-resistant fabric for softness. Use ties to keep cushions secured.
The possibilities are endless! The bench you can build is limited only by your imagination.
