What’s Included in the Box

When the delivery arrived, I was surprised by the number of boxes: four large, heavy cartons. Inside, I found:

• Galvanized steel roof panels and wall panels
• 18-gauge steel trusses and beam components
• Base floor kit with steel frame sections and hardware
• Polycarbonate skylight panels (4 pieces)
• Ventilation grilles (4 pieces)
• Front double doors and side door with hinges and locks
• Hardware bags with bolts, nuts, washers, and anchors
• Assembly instructions (paper manual + QR code for video)
• Gloves and a basic tool kit (though you’ll need better tools)

The packaging was sturdy, and all parts arrived without significant damage. The first impression: the steel panels are thick and heavy, and the powder coating looks uniform. However, the manual could be clearer—more on that later. If you’re wondering if the WACASA shed review honest opinion matches the unboxing, so far so good.

How to Use WACASA 13x20x8.3 FT Large Metal Garage Shed with Base Floor Kit, Ultra-Reinforced 18-Gauge Powder-Coated Steel Frame, 100 PSF Snow & 150 MPH Wind Rated, Skylight Dual-Entry Carport & Workshop: Complete Guide

Step 1: Site Preparation & Foundation

Choose a level location. For permanent installation, a concrete slab is best. I poured a 13×20 slab and let it cure for a week. If using soil or gravel, you’ll need to buy heavy-duty auger anchors (30-36 inches long) separately. Mark the footprint, lay out the base frame pieces, and bolt them together. Ensure squareness using diagonals.

Step 2: Assemble the Floor Kit

WACASA provides a steel floor frame that sits on the slab. Assemble the perimeter beams and cross supports. The kit includes pre-drilled holes for the anchors. I used the included concrete anchors (expansion bolts) to secure the base to the slab. Level the frame with shims if needed.

Step 3: Build the End Walls

The instructions recommend assembling each end wall on the ground and then raising it. Attach the vertical posts, door frames, and truss connectors. The side door goes on one end. Use the supplied bolts—do not overtighten at first. Raise the wall and temporarily brace it.

Step 4: Install Side Walls & Trusses

Attach side wall panels to the base and the end walls. Then lift the double-reinforced trusses into place. This step requires at least two people; the trusses are heavy but manageable. Secure them with the provided brackets. The truss system is the key to the wind rating—make sure every bolt is tight.

Step 5: Add Roof Panels & Skylights

Lay the roof panels starting from one end, overlapping per the manual. Insert the polycarbonate skylights into the designated cutouts. Seal the edges with the included weatherstripping to prevent leaks. Install the ridge caps and vent grilles. The vents align with the truss openings to create a passive airflow path.

Step 6: Install Doors & Hardware

Hang the front double doors and the side single door. Adjust the hinges for smooth operation. Install the lock cylinders and handles. Both doors close securely with a positive latch.

Step 7: Final Anchoring & Adjustments

Go back and tighten all bolts fully. If using auger anchors (for dirt), drive them into the ground through the base frame holes. Add the corner braces and any optional wind ties. Seal any exposed gaps with silicone caulk (not included).

Step 8: Daily Use & Maintenance

Once assembled, you can park a car, ATV, or store equipment. The 8-foot peak allows standing room for most people. The skylights provide adequate light for daytime tasks. Wipe down panels occasionally, and check bolts twice a year. Lubricate door hinges annually. The base kit’s ventilation channels help prevent moisture buildup, but adding a dehumidifier is wise in humid climates.

Performance & Real-World Testing

Testing Methodology

I installed this shed in early spring on a concrete slab in an area that gets moderate winds (up to 40 mph typical) and occasional heavy rain. Over four weeks, I monitored structural stability, water ingress, and daily temperature/humidity inside. I also simulated snow load by stacking sandbags on a small section (not the full 100 PSF due to safety concerns, but enough to test deflection).

Structural Performance

The shed feels incredibly solid. During a 35 mph windstorm, I noticed no flexing or rattling. The truss system distributes loads well. The 18-gauge internal frame makes a significant difference compared to thinner 28-gauge kits. The base floor kit supports my riding mower and workbench without deflection.

Moisture & Ventilation

With the vents open, interior humidity stayed within 10% of outdoor levels. Condensation on the metal panels was minimal, thanks to the ventilation channels and roof slope. The skylights don’t leak; I tested with a hose. However, in heavy driving rain, a few drops came in around the door seals—I added extra weatherstripping to solve it.

Claims vs. Reality

WACASA claims 100 PSF snow load and 150 mph wind. While I couldn’t test those extremes, the engineering (heavy trusses, multiple connection points) is convincing. For typical residential use, this shed will outperform any non-reinforced structure. The WACASA 13x20x8.3 FT garage shed review verdict is that it delivers on its promise of durability. The only performance gap I found is the instruction manual—it lacks detail for some steps, especially anchoring. Novice builders will need online videos.

Pros and Cons

What We Loved (Pros)

• Exceptional Build Quality: The 18-gauge internal truss system is overbuilt for the price. This is why the WACASA metal garage shed review and rating stands out.
• Weather Resistance: High wind and snow ratings give peace of mind. Properly anchored, it can handle severe storms.
• Natural Lighting: Four skylights make the interior usable without electricity during the day.
• Dual Entry: The side door is great for quick access without opening the big doors.
• Included Base Kit: Many competitors charge extra for a floor frame. WACASA includes a robust one.
• Generous Size: 260 sq ft fits two cars or a car plus workshop area.

What Could Be Improved (Cons)

• Complex Assembly: The manual is mediocre. Expect 12-20 hours with two people. Clearer diagrams would help.
• Missing Hardware for Non-Concrete Ground: Auger anchors are not included. You must buy them separately for soil/gravel.
• Door Seals: The standard weatherstripping could be thicker; I recommend upgrading.
• Price: At $1,899.85, it’s not cheap, but it’s competitive for the quality. See the WACASA shed review honest opinion on value below.

Expert Tips for Maximum Value

Tip #1: Plan Your Foundation Carefully

A concrete slab with proper rebar and a level surface will maximize the shed’s wind resistance and longevity.

Tip #2: Upgrade Door Seals During Assembly

Buy a roll of 1/2-inch thick rubber weatherstripping and apply it before hanging doors. It reduces dust and water ingress.

Tip #3: Add LED Strip Lights

The skylights help, but for evening work, install battery-powered or wired LED strips along the trusses. Use magnets for easy mounting.

Tip #4: Use Threadlocker on Critical Bolts

Apply blue Loctite to bolts that connect trusses to walls, and those near the doors. Vibration from wind can loosen them over time.

Tip #5: Buy Extra Anchors

If installing on soil, get six heavy-duty auger anchors (30-36 inches) rather than the minimum four. It’s cheap insurance.

Tip #6: Seal the Base Frame Contact Points

Apply a bead of silicone caulk under the base frame where it sits on the slab. This prevents water from seeping under the steel.

Tip #7: Consider a Interior Floor Coating

The steel base is strong, but applying an epoxy floor coating makes it easier to clean and protects against chemical spills.

Common Mistakes to Avoid

1. Mistake: Skipping the foundation prep → Solution: Always level the ground or slab; uneven bases cause panel gaps and leaks.
2. Mistake: Overtightening bolts during initial assembly → Solution: Hand-tighten only until all parts are aligned, then fully torque to avoid stripping threads.
3. Mistake: Not using sealant on roof panel overlaps → Solution: Apply the included (or additional) sealant tape; otherwise, water can wick through.
4. Mistake: Assembling alone → Solution: Recruit at least one helper, especially for raising trusses and roof panels.
5. Mistake: Ignoring anchoring for soil → Solution: If not on concrete, purchase and install auger anchors per manufacturer guidelines.

Frequently Asked Questions

Is WACASA 13x20x8.3 FT Large Metal Garage Shed with Base Floor Kit, Ultra-Reinforced 18-Gauge Powder-Coated Steel Frame, 100 PSF Snow & 150 MPH Wind Rated, Skylight Dual-Entry Carport & Workshop worth the money?

Absolutely. Priced around $1,900, it delivers a 260 sq ft building with a heavy-duty steel frame that competes with sheds costing $2,500+. The included base kit and high wind/snow ratings add significant value. Over 10+ years of use, the cost per year is minimal compared to replacing cheaper carports every few seasons.

How does it compare to Arrow steel sheds?

Arrow sheds typically use thinner gauge steel (28 ga vs. 23 ga panels) and lower snow loads (40 PSF vs. 100 PSF). WACASA’s truss system is also more robust. Arrow is cheaper but not designed for severe weather. If you need a budget-friendly light-duty shelter, Arrow; if you need longevity and storm protection, WACASA wins.

What’s the learning curve for beginners?

Moderate to high. If you have basic DIY skills (using a power drill, reading measurements), you can manage. Plan on two weekends with a helper. The main challenge is raising the trusses and roof panels – they’re heavy but manageable. Online assembly videos help fill gaps in the manual.

What accessories or additional items do I need?

For concrete: concrete anchors (included), but you may want extra if your slab is uneven. For soil: heavy-duty auger anchors (30-36 inch) purchased separately. I also recommend extra weatherstripping, silicone caulk, and a threadlocker. Optional: LED lights, shelving, and a dehumidifier. See our solar battery kit for power independence.

What warranty and customer support does it offer?

WACASA provides a 1-year limited warranty on structural parts. Customer support via Amazon messaging; I received a response within 24 hours. Returns are handled through Amazon’s 30-day policy. Extended warranty options aren’t available directly, but Amazon’s A-to-Z coverage applies.

Where can I buy WACASA 13x20x8.3 FT Large Metal Garage Shed with Base Floor Kit, Ultra-Reinforced 18-Gauge Powder-Coated Steel Frame, 100 PSF Snow & 150 MPH Wind Rated, Skylight Dual-Entry Carport & Workshop at the best price?

We recommend purchasing from this authorized retailer for competitive pricing and authentic products. Amazon often runs deals, and Prime members get free shipping. Check the price regularly for fluctuations.

Can this shed be assembled on a gravel base?

Yes, but you must use heavy-duty auger anchors (30-36 inches long) to secure it. The gravel should be compacted and leveled. The included base kit sits on top. The shed’s wind rating applies only when properly anchored; without anchors, it’s much less stable.

Does the shed come with a floor?

Yes, it includes a galvanized steel floor frame kit that provides ventilation channels and supports heavy items. You do not need a separate plywood or concrete floor, though many users add a plywood overlay for aesthetics.
