Backyard entertaining has moved well beyond the basic patio set, and the Costco bar shed has become one of the most talked-about outdoor structures for homeowners who want a dedicated serving and socializing space without a full renovation. Part storage shed, part outdoor bar, these prefab units promise a turnkey backyard upgrade. But is the reality as appealing as the warehouse floor display?
What Is a Costco Bar Shed?
Costco periodically stocks prefabricated shed structures that double as outdoor bars, typically from brands like Yardistry, Backyard Discovery, and Studio Shed. The most popular models feature a cedar or composite frame, a solid roof with shingles, a built-in bar counter with overhang for stools, interior shelving, and a lockable door for secure storage.
Sizes typically range from 8×12 feet to 12×16 feet, with the bar counter running along one exterior wall. Some models include electrical knockouts for running wiring, though power isn’t included. Prices at Costco typically fall between $3,500 and $8,000 depending on size, material, and features.
Popular Models and Features
Availability rotates seasonally, but these configurations appear most frequently:
- Yardistry Cedar Bar Gazebo (10×14 ft): Open-air design with aluminum roof, built-in cedar bar top, and storage shelving. Around $4,500-$5,500.
- Backyard Discovery Bar Shed (12×10 ft): Enclosed shed with swing-out bar counter, shingled roof, interior hooks and shelves. Approximately $5,000-$6,500.
- Studio Shed-style kits: More modern aesthetic with clean lines, composite panels, and optional sliding barn door. These premium models can reach $7,000-$8,000.
Most units come with pre-cut lumber, pre-drilled holes, and detailed instruction manuals. Hardware, fasteners, and roofing materials are included in the kit. Stain or paint is not typically included.
Assembly: What to Expect
Don’t let the “prefab” label fool you. Assembling a costco bar shed is a serious project. Most manufacturers estimate 20-40 hours of build time with two people. Realistically, plan for a full weekend with a helper, or two weekends if you’re working at a moderate pace.
You’ll need basic tools: a drill/driver, socket set, level, ladder, and rubber mallet. A second set of hands is mandatory for raising wall panels and setting roof beams. Some owners hire a handyman for the roof portion alone, which typically costs $300-$600 for a day of labor.
Foundation requirements depend on your model and local codes. Most need a level gravel pad, concrete pavers, or a poured concrete slab. Budget an additional $500-$1,500 for site preparation if you don’t already have a suitable surface.
Permits and HOA Considerations
Before ordering, check your local building codes and HOA rules. Many municipalities require permits for structures over 100-120 square feet. Setback requirements, which dictate how close you can build to property lines, vary widely. Common restrictions include:
- Minimum 5-10 feet from rear and side property lines
- Maximum height of 12-15 feet for accessory structures
- Electrical permits if you plan to run power
- HOA architectural review and approval, which can take 2-6 weeks
Skipping permits can result in fines and forced removal, so verify requirements with your local building department before the delivery truck arrives.
Adding Power, Plumbing, and Extras
A bar shed really comes alive with electricity. Running a dedicated 20-amp circuit from your main panel to the shed typically costs $500-$1,200 through a licensed electrician, depending on distance and whether the run is underground or overhead. This gives you lighting, a mini fridge, and a blender without tripping breakers.
Plumbing for a wet bar with a small sink is possible but adds significant cost, usually $1,500-$3,000 for the plumbing run plus fixtures. Many homeowners skip plumbing entirely and use a cooler for ice and a bus tub for cleanup.
Popular upgrades that don’t require contractors include string lights, battery-operated LED puck lights, a wall-mounted bottle opener, a chalkboard menu, and outdoor-rated bar stools in the $50-$150 range.
Costco Bar Shed vs. Custom Build
A custom-built outdoor bar structure from a local contractor typically runs $10,000-$25,000 for comparable square footage with electrical and basic finishes. The costco bar shed delivers roughly 60-70% of that custom experience at 30-40% of the cost. The trade-off is limited customization, standard sizing, and the DIY assembly requirement.
Where custom builds win: exact dimensions for your space, material choices, built-in appliances, and professional-grade finishes. Where Costco wins: speed (delivered in one shipment), predictable cost, and Costco’s generous return policy if the product doesn’t meet expectations.
Maintenance and Longevity
Cedar models need staining or sealing every 2-3 years to prevent graying and moisture damage. Composite and engineered wood panels require less maintenance but may fade in direct sun over time. Inspect the roof annually for loose shingles and seal any gaps around windows or the bar counter opening.
Well-maintained, a quality bar shed should last 15-20 years in most climates. In harsh winter regions, consider closing the bar opening with a removable panel during off-season months to protect the interior from snow and ice intrusion.
Is It Worth It?
For homeowners who entertain regularly and want a dedicated outdoor bar without a five-figure custom build, the Costco bar shed hits a practical sweet spot. Budget $5,000-$10,000 total including the kit, foundation, assembly help, and basic electrical. You’ll end up with a functional, attractive structure that adds genuine usable space to your backyard and a solid talking point at every gathering.
