Simple Outdoor Bench

Difficulty: Intermediate · Estimated time: about 5 hr of hands-on work, not counting glue and finish drying or cure time

A sturdy patio bench from 2x lumber with bolted legs — no fancy joinery.

Build a weather-ready bench using pressure-treated or cedar 2x4/2x6 stock. Through-bolted legs and a slatted seat. Intermediate mainly for size, square assembly, and outdoor fastening — still hobbyist-safe with basic power tools.

Materials

• 2x4 lumber (cedar, or PT rated for ground contact) — 6 @ 8 ft (Choose straight stock)
• 2x6 for seat slats (optional upgrade) — 2 @ 8 ft (Or use 2x4 slats)
• Carriage bolts with washers/nuts — 8 @ 3/8" x 3-1/2"
• Exterior screws — 1-1/4 lb @ 2-1/2"
• Exterior finish or leave cedar raw — 1 qt if finishing

Tools

• Miter or circular saw
• Drill/driver and 3/8" bit
• Square, tape, pencil
• Wrenches for bolts
• Clamps (optional)
• Sander (optional)
• Safety glasses and hearing protection

Safety: Power tools and finishes can cause serious injury. Read and follow every tool and product manual, use guards and push sticks, wear eye and hearing protection, and work in a ventilated area. These plans are for general information; check measurements and your own skill before cutting. You build at your own risk, and Handy at Home is not liable for injury or damage. See the Terms.

Steps

1. Cut the parts

   Typical size: seat 48" long, height ~17". Cut four legs, two long aprons, two short aprons/ends, and 4–5 seat slats. Label everything. Seal fresh PT end cuts if using treated lumber.

   • Crown boards so crowns oppose on paired parts.
   • Cut one leg and use it as a pattern for the rest.

2. Build the leg assemblies

   Assemble two end frames: legs + short apron, square and bolted or screwed. Add a lower stretcher between legs on each end for racking resistance. Predrill for bolts; use washers under nuts.

   • Assemble on a flat driveway or sheet of plywood.
   • Do not overtighten bolts into soft wood — snug plus a quarter turn.

3. Join the base and add seat

   Connect end frames with long aprons. Check diagonal measurements for square. Screw seat slats with ~3/8" gaps for drainage; countersink heads slightly. Ease all sharp edges.

   • A spacer stick keeps slat gaps consistent.
   • Sit and rock-test before finish — fix wobble by planing a high foot or adding an adjustable glider.

4. Finish and place outdoors

   Sand splinters smooth. Apply exterior oil/stain if desired. Place on level ground; use pads under feet on soft soil. Recheck bolts after the first season.

   • PT lumber must dry before many film finishes stick.
   • Store under cover in harsh winters to extend life.
