DIY step-by-step: Build a simple planter bench
This straightforward project creates a 6-foot bench with a shallow planter behind it — ideal for small decks and beginner woodworkers.
Materials and tools
- Pressure-treated 2x4s (frame) and 1×6 decking boards (seat)
- Rot-resistant boards or composite for planter box (1×6 or 2×6)
- 3/4″ exterior plywood for planter bottom
- Galvanized screws, wood glue, exterior wood primer/paint or stain
- Landscape fabric for planter liner, drainage gravel, potting soil
- Drill, circular saw, measuring tape, speed square, clamps
Step-by-step build
- Measure your deck area and mark a 6′ bench position. Sketch dimensions: seat height 18″, planter behind at 12–16″ depth.
- Build the bench frame using 2x4s: two end frames and 1–2 center supports. Attach long rails across the top and bottom.
- Fasten decking boards to the top of the frame for the seat. Leave small gaps for drainage and expansion.
- Construct planter box: assemble four sides with exterior plywood bottom, drill drainage holes (1/2″ spaced). Line with landscape fabric and add gravel.
- Attach planter to back of bench frame with galvanized screws and brackets. Ensure weight is supported by the bench base, not just the deck railing.
- Finish: sand edges, apply two coats of exterior stain/paint or sealant. Add soil and plants once finish is fully cured.
Design tips and real-world advice
- Drainage: Always add drainage holes and a gravel layer to planter boxes to prevent root rot and wood damage.
- Weight: Planter boxes can get heavy when wet. Keep planters shallow if your deck has load limits; use lightweight potting mixes or plastic inserts to reduce weight.
- Plant selection: Use drought-tolerant and shallow-rooted plants for deck planters — succulents, sedums, herbs, and compact perennials work well.
- Material choices: Composite decking resists rot and reduces maintenance; cedar and teak offer natural resistance with beautiful grain patterns.
- Finish and color: Match bench stain to deck boards for a cohesive look or paint planters in an accent color for a pop.
- Comfort: Add cushions and backrests. Use quick-dry outdoor foam and weatherproof fabric for low-maintenance seating.
Frequently Asked Questions
1. How do I prevent water damage to my deck under planter boxes?
Place a waterproof membrane or rubber feet under planters, provide drainage holes, and add a drip edge or small gap between the planter and deck boards. Elevating the planter slightly improves airflow and prevents trapped moisture.
2. Can I build a planter bench on a second-story deck?
Yes, but consult your deck’s load rating first. Use lightweight materials and smaller planters, and avoid overly deep soil beds. If unsure, ask a structural professional before adding permanent heavy features.
3. What are the best plants for a deck planter bench in hot, sunny climates?
Choose drought-tolerant species such as lavender, rosemary, sedum, lantana, and ornamental grasses. Use a well-draining potting mix and consider installing a simple drip irrigation or self-watering inserts for consistent moisture.
