Transform your backyard or patio into a welcoming space with a DIY bench to picnic table conversion. This versatile project allows you to create a comfortable seating area that can easily be converted into a dining space for al fresco meals. Here's a step-by-step guide to help you build your own bench to picnic table, complete with tips and tricks to optimize your search for the best materials and tools.
Gather Your Materials and Tools
Before you begin, make sure you have all the necessary materials and tools on hand. For this project, you'll need:
- Two 8-foot long 2x4 pressure-treated lumber boards
- One 8-foot long 2x6 pressure-treated lumber board
- One 4-foot long 2x4 pressure-treated lumber board (for the tabletop)
- 2.5-inch and 1.5-inch exterior wood screws
- Exterior wood glue
- Circular saw
- Drill with driver bits
- Tape measure
- Pencil
- Safety glasses
- Work gloves
- Stainless steel or galvanized hardware (for added durability)
Design and Cut List
First, determine the dimensions of your bench to picnic table. For this example, we'll create a bench that's 6 feet long and 18 inches deep, with a tabletop that's 30 inches wide and 18 inches deep. Here's a cut list based on these dimensions:

| Piece | Cut Size | Quantity |
|---|---|---|
| Legs | 2x4 @ 28.5 inches | 4 |
| Supports | 2x4 @ 17.5 inches | 4 |
| Backrest | 2x4 @ 58 inches | 1 |
| Tabletop | 2x4 @ 42 inches | 1 |
| Tabletop Supports | 2x4 @ 17.5 inches | 2 |
Build the Bench Frame
Start by building the bench frame. Attach two legs together using 2.5-inch screws and wood glue, creating an 'L' shape. Repeat this process to create two 'L' shaped pieces. Next, attach the supports to the legs using 2.5-inch screws and wood glue, creating a rectangular frame. Finally, attach the backrest to the top of the legs using 2.5-inch screws and wood glue.
Add the Tabletop
To create the picnic table function, attach the tabletop supports to the inside of the bench frame using 2.5-inch screws and wood glue. Ensure the supports are level and 18 inches from the ground. Next, attach the tabletop to the supports using 1.5-inch screws and wood glue. To make the tabletop more stable, you can add additional support boards underneath, attaching them to the tabletop and the bench frame.
Finishing Touches
Once the bench to picnic table is complete, you can stain or paint it to match your outdoor decor. Allow the stain or paint to dry completely before using the bench. To maintain the longevity of your DIY project, consider applying a sealant to protect the wood from the elements.

By following these steps, you'll have a versatile bench to picnic table that's perfect for relaxing or dining al fresco. Happy building!
