Materials and Tools You Need to Build an Outdoor Storage Bench

Shopping List (Standard 48″W Bench)

This list covers the most popular beginner build, a cedar slat bench with a hinged lid and full-width storage compartment. Think of it as your complete materials list before you set foot in the hardware store.

Lumber:

• 6 × 2x4x8 cedar boards (frame and seat slats), approx. $6, $8 each at Home Depot
• 2 × 1x6x8 cedar boards (front/back panels), approx. $10 each
• 1 × sheet of 3⁄4″ exterior-grade plywood (bottom panel), approx. $30

Hardware:

• 1 × 48″ piano hinge (for the lid), approx. $15
• Box of deck screws (2″ and 3″), approx. $10
• 2 × lid support chains or lid supports, approx. $8
• Wood glue (exterior grade), approx. $5

Finishing:

• Sandpaper (80, 120, 220 grit)
• Exterior wood stain or sealer (Thompson’s WaterSeal or Minwax Helmsman)

Total estimated cost: $80, $110

Want to cut that in half? Swap the dimensional cedar for cedar fence pickets, they run about $2, $3 each at Home Depot and Lowe’s and are more than strong enough for a bench seat and frame.

Tools You’ll Need

• Circular saw or miter saw
• Drill/driver
• Kreg Jig (optional but highly recommended for pocket holes)
• Tape measure
• Speed square
• Clamps (at least 4)
• Sander or sanding block

You don’t need a full workshop. A basic drill, a circular saw, and a Kreg Jig will handle 90% of this build.

Outdoor Storage Bench Dimensions: Width, Height, and Depth Guide

Getting the bench dimensions right matters more than most people think. Build it too shallow and it’s uncomfortable to sit on. Build it too tall and your feet dangle. Here’s the breakdown.

Standard Bench Dimensions

19 1/2 inches tall is the sweet spot for most adults. It’s comfortable for sitting and matches the height of most patio chairs. If you’re building a front porch bench that doubles as a seat and step, you might go lower, around 16-17 inches.

17 inches deep gives you a comfortable outdoor bench seat without making the bench feel like a park bench. It also provides roughly 13-14 inches of usable internal storage depth.

Is 12 Inches Deep Enough for a Bench?

Technically, yes, but it’s not comfortable for most adults. A 12-inch depth feels cramped and forces you to perch rather than sit. The standard depth of an outdoor bench is 15-18 inches. Stick to at least 17 inches deep for a daily-use storage bench.

How Deep Should a Built-In Storage Bench Be?

A built-in storage bench is typically 18-20 inches deep because it’s fixed to a wall or deck railing, so you can use the full depth for seating. The storage compartment underneath can go as deep as the structure allows, usually 12-16 inches of clear interior space.

How to Build an Outdoor Storage Bench in 8 Easy Steps

This is a step-by-step guide for the most popular design: a 48-inch cedar bench with a hinged lid and open-bottom storage compartment. Skill level: beginner. These build plans follow a simple design that first-timers can tackle with confidence, no advanced joinery, no specialized equipment.

Step 1, Cut Your Lumber to Length

Start with your cut list. Using 2x4x8 cedar boards:

• 4 pieces at 48″ (seat frame front/back and interior supports)
• 4 pieces at 14″ (seat frame sides and interior supports)
• 4 pieces at 16″ (legs)
• Slats: 7-8 pieces at 48″ from 1×4 or fence pickets (lid and front panel)

Measure twice. Cut once. Yes, that’s a cliché. It’s also the most violated rule in woodworking.

Step 2, Build the Base Frame

Assemble a rectangular frame using two 48″ boards and two 14″ boards. Use deck screws (3″) and a Kreg Jig for pocket holes if you have one. This is the bottom of the storage compartment.

Step 3, Attach the Legs

Cut four legs to 16″ from 2×4 cedar. Attach one to each corner of the base frame, flush with the outer edges. Use two deck screws per leg, plus wood glue for extra strength.

Step 4, Build the Upper Frame (Seat Frame)

Repeat Step 2 to create a second rectangular frame identical to the base. This sits on top of the legs and forms the perimeter of the seat area. Attach it to the top of the legs with screws.

Step 5, Add Interior Supports

Add one or two horizontal supports across the middle of the upper frame (the 14″ pieces) to support the lid when it’s closed. These also stiffen the whole structure.

Step 6, Build the Lid

Cut 7-8 slat boards to 48″ for the slat design lid. Space them evenly (about 1⁄4″ gap between slats) across two shorter 2×4 cross pieces. Screw from below so no fasteners show on top. This is your bench seat and lid in one.

Step 7, Attach the Piano Hinge

Flip the lid upside down. Position it flush against the back of the upper frame. Attach the piano hinge along the full back edge, one side to the lid, one side to the top of the back frame board. A full-length piano hinge distributes weight evenly and prevents warping over time.

Add lid support chains or lid supports on both inside ends so the lid doesn’t swing back and stress the hinge.

Step 8, Add Panels, Sand, and Finish

Attach cedar boards or plywood panels to the front and sides of the bench frame to enclose the storage compartment. Leave the bottom open (great for ventilation) or add a plywood floor if you’re storing items that need a flat surface.

Sand everything, start with 80-grit to knock off rough edges, then 120-grit, then 220-grit for a smooth finish.

Apply two coats of Thompson’s WaterSeal or a Minwax exterior stain. Let dry fully between coats.

That’s it. Your outdoor storage bench is done.

Best Wood for an Outdoor Storage Bench (Cedar, Pine, Pressure-Treated)

This question comes up in every beginner woodworking forum, and the answer isn’t one-size-fits-all. Here’s how the main options compare.

Cedar, The Best All-Around Choice

Cedar is naturally rot-resistant, lightweight, and easy to work with. It smells great fresh-cut, holds screws well, and weathers beautifully to a silver-gray if left unfinished. It’s the go-to wood storage bench material for garden storage bench and porch storage bench projects, and for good reason.

Using cedar fence pickets instead of dimensional cedar lumber cuts your material cost significantly. Eight pickets at a hardware store typically cost $20, $30 total, less than two 2x4x8 cedar boards.

Pressure-Treated Lumber, Best for Ground Contact

Pressure treated lumber is treated with chemicals that prevent rot and insect damage. It’s ideal for a built-in storage bench that sits directly on a deck or ground-level patio. It’s heavier and harder to cut than cedar, and it needs time to dry before finishing. It’s also slightly rougher to work with, so it’s less ideal for seats where skin contact is frequent.

Pine, Budget Option with Trade-Offs

Pine is cheap and easy to find, but it’s not naturally rot-resistant. If you build with pine, you must seal it well and reapply finish every year or so. It works fine for a front porch bench that’s under cover, but it’ll struggle exposed to full weather cycles without consistent maintenance.

Design Variations: Hinged Lid, Slat Design, Pallet Bench, and More

Not every outdoor storage bench looks the same. Here’s a breakdown of the most popular styles, with honest pros and cons for each.

Hinged Lid Bench

The most popular design by far. The entire seat lifts up on a piano hinge to reveal the storage compartment below. Clean, functional, and easy to access.

Pros: Easy access, keeps contents dry, looks polished

Cons: Takes more hardware, lid can warp if not built correctly

This is the design covered in the step-by-step section above. It works for pool side storage (towels, floats), front porch (shoes, umbrellas), and backyard patios (cushions, garden tools).

Slat Design Bench

A slat design uses evenly spaced boards for the seat and sometimes the sides. It has a classic, airy look and handles rain well because water drains through the gaps.

Pros: Great drainage, classic look, easy to build

Cons: Not ideal for storing small items (they can fall through the gaps)

Many free plans on Ana White and Pinterest use this design because it’s forgiving for beginners, small gaps hide minor inconsistencies.

Pallet Bench with Storage

A pallet bench with storage uses reclaimed wood pallets as the main structure. You stack two pallets, add a simple lid, and you have a bench for almost nothing.

Pros: Nearly free, eco-friendly, rustic aesthetic

Cons: Pallets vary in size and quality, some are treated with chemicals not safe for home use. Always check the pallet markings (HT = heat treated = safe; MB = methyl bromide = avoid).

Built-In Storage Bench

A built-in storage bench is attached to a wall, deck railing, or fence. It’s fixed in place and often spans a longer run, 6 to 12 feet, for maximum seating and storage.

Pros: Maximizes space, looks intentional and custom

Cons: Requires more planning and basic carpentry skills, not portable

This style is common on decks and pergolas. If you’re building one, pressure treated lumber for the frame is recommended. It also falls squarely in the category of outdoor storage furniture that adds real value to your space, both functionally and visually.

How to Save Money: Building with Cedar Fence Pickets

If budget is a concern, and let’s be honest, it usually is, cedar fence pickets are the single best cost-cutting move in this entire project.

Standard cedar pickets are 1⁄2″ to 3⁄4″ thick and 51⁄2″ wide, sold in 6-foot lengths. At Home Depot or Lowe’s, they typically run $2.50, $4 each. Compare that to a full 1×6 cedar board at $10, $14, and the math is obvious.

A complete outdoor storage bench using cedar fence pickets for the panels, lid slats, and trim, combined with standard 2x4s for the structural frame, comes in at $40, $60 total. That’s a real build, not a downgraded one.

The 2x4s handle all the load-bearing work (frame and legs), so the pickets just need to look good and keep the structure enclosed. They do that job perfectly.

For beginner woodworking, this combo is almost impossible to beat on value. Search “DIY outdoor storage bench with cedar fence pickets” on YouTube, channels like Backyard Life have built entire tutorial series around this exact approach.

If you’d rather skip the trial-and-error and get proven outdoor furniture plans with full cut lists and shopping lists already tailored to fence picket builds, this plan pack is worth checking out, it covers multiple bench styles in one download.

Finishing, Weatherproofing, and Maintaining Your Outdoor Wood Bench

Sanding and Prep

Before any finish goes on, sand the entire bench. Work through grits: 80 → 120 → 220. Pay extra attention to the seat surface, this is where skin and fabric contact happens most.

Wipe down with a tack cloth or damp rag to remove all dust before applying any finish.

Best Finishes for Outdoor Wood

Thompson’s WaterSeal is the most common clear exterior sealer for outdoor wood projects. It repels water, resists UV fading, and dries clear. Apply two coats. It’s available at virtually every hardware store.

Minwax Helmsman Spar Urethane gives a slightly amber tone and more gloss. It’s excellent for painted or stained benches where you want a durable top coat.

For a colored finish, use an exterior-grade deck stain before the sealer. This gives you UV protection plus color in one step.

Maintenance Schedule

• Every spring: Inspect for cracks, loose screws, and peeling finish
• Every 1-2 years: Reapply exterior sealer or stain
• After heavy rain seasons: Let the bench dry fully before storing cushions or items inside

One tip most people skip: store the bench’s removable cushions inside during winter, or at least inside the storage compartment itself. The bench frame handles weather fine, cushions don’t.

Beginner Woodworking Tips Before You Start

Building your first outdoor storage bench as a beginner woodworking project is totally doable. But here are a few things that’ll save you frustration:

• Pre-drill all your holes near the ends of boards to prevent splitting, especially with cedar and pine
• Clamp before you screw, boards shift during fastening, and a clamp keeps everything aligned
• A Kreg Jig is worth it, pocket hole joints are strong, fast, and hide fasteners for a cleaner look
• Label your cut pieces with painter’s tape and a marker right after cutting, it sounds obvious until you have 22 pieces on the garage floor looking identical
• Don’t skip the finish, bare cedar lasts a few seasons; sealed cedar lasts a decade or more

Free plans from Ana White are a great starting point for true beginners. Her instructions assume you’re starting from zero and explain every step without jargon.

FAQ, Outdoor Storage Bench Plans

How much does it cost to build an outdoor storage bench from scratch?

Most DIY outdoor storage benches cost between $40 and $120 in materials, depending on the wood you choose. Using cedar fence pickets instead of dimensional lumber is the biggest money-saver, you can build a solid bench for under $50 that way.

Can I use cedar fence pickets to build a storage bench?

Yes, and it’s one of the most budget friendly options available. Cedar fence pickets are usually sold in bundles at Home Depot or Lowe’s for a fraction of the cost of dimensional cedar. They’re light, naturally rot-resistant, and easy to cut and sand.

How long does it take to build a DIY outdoor storage bench?

A beginner can finish a basic outdoor storage bench in one weekend, roughly 6 to 10 hours of work. More complex builds with a piano hinge lid or a built-in storage bench design may take an extra half-day for finishing and hardware installation.

What tools do I need to build an outdoor storage bench?

At minimum, you’ll need a circular saw or miter saw, a drill/driver, a tape measure, a square, and clamps. A Kreg Jig is extremely helpful for pocket hole joinery, especially for beginners who want clean, strong joints without visible fasteners.

How do I weatherproof a wooden outdoor storage bench?

Sand the wood smooth, then apply at least two coats of an exterior-grade finish. Thompson’s WaterSeal works well for a clear protective coat, while Minwax makes stains that add color and UV protection. Reapply every one to two years for lasting protection.

What is the ideal height for a sitting bench with storage?

The standard comfortable sitting height is 17 to 19 inches from the floor to the top of the seat. The most commonly cited target in bench plans is 19 1/2 inches tall, which works for most adults and pairs well with standard patio table heights.
