The best 11-foot cantilever patio umbrella with a base is a complete shade system: the canopy, offset frame and its specified ballast base must belong together. Grand Patio’s 11FT round Champagne umbrella is our first choice for a curved-arm design with a crank. Costway’s OP70377 is the alternative for shoppers who want pedal-operated rotation.
Both choices include a base that you must fill. Neither arrives as a ready-to-use, fully weighted umbrella. Our comparison uses manufacturer specifications and assembly instructions; the recommendations are editorial judgments, without hands-on testing.
Two 11-foot umbrellas with an included base
| Umbrella | Canopy and controls | Included base and filling | Best reason to choose it |
|---|---|---|---|
| Grand Patio 11FT round, Champagne; B08CVTKRRR | Nominal 11-foot round canopy; crank opening and curved offset arm | Wheeled reservoir base. This selected listing specifies 330 lb of sand plus 44 lb of water. | A curved-arm option with a clearly identified included-base listing |
| Costway OP70377, Tan | 11-foot diameter, eight-rib canopy; push-button opening and 360-degree pedal rotation | Reservoir base with four wheels. Maker lists 220 lb filled with water or 330 lb with sand and water. | Repositioning the shade without relocating the entire base |
These are nominal round canopy dimensions, not 11-foot-square footprints or guarantees of an 11-foot patch of shade throughout the day. The ribbed outlines are polygonal, and the shaded area changes with the sun.
1. Grand Patio 11FT round umbrella: our first choice
Grand Patio 11FT Round Cantilever Umbrella with Base, Champagne
As an Amazon Associate we earn from qualifying purchases.
Choose the 11FT / Champagne version of this listing. It combines a polyester canopy, aluminum pole, eight steel ribs and a large wheeled base. The curved arm keeps the main support outside the seating area, while the crank opens the canopy. Its main appeal is a complete, identifiable umbrella-and-base package rather than a frame that leaves you sourcing compatible ballast separately.
Base requirement: the selected listing calls for 330 lb of sand plus 44 lb of water. The linked Napoli assembly manual separately gives a minimum base weight of 264 lb and says to fill the reservoir and tighten its cap. That lower manual minimum is not a reason to ignore the larger fill instruction on this particular listing. Confirm the supplied instructions match the delivered base before assembly. See the exact product listing and Napoli manual, page 4.
Pros: the base is included; wheels help with positioning; the offset arm leaves the space beneath the canopy open. Cons: buying and handling the ballast is a substantial extra job, and the filled base needs a permanent patch of usable patio space. Do not assume the 12-foot version or another seller’s fill instructions apply to this 11-foot configuration.
The manual says to retract the umbrella during extreme weather, never leave it unattended, and secure its strap when unused. It excludes damage caused by failing to close it. Grand Patio’s limited warranty covers qualifying defects for one year and excludes circumstances including misuse, improper assembly and extreme weather. This is not a wind-speed guarantee.
2. Costway OP70377: best for pedal rotation
The Costway OP70377 in Tan has an 11-foot-diameter polyester canopy, a powder-coated aluminum frame and eight ribs. Its foot pedal allows 360-degree rotation, and its opening mechanism uses a button. Choose it if changing the canopy’s direction matters more to you than a conventional crank.
The included base contains fillable reservoirs beneath its cover and has four wheels. Costway lists a filled weight of 220 lb with water or 330 lb with sand and water. Those figures describe this model’s base; they do not apply to Grand Patio or to a fabric sandbag base. The assembly manual illustrates the reservoir components and their installation. See the Costway OP70377 product page and buying options and its manufacturer-linked OP70377 manual.
Pros: included fillable base, pedal rotation and an adjustable offset canopy. Cons: a large filled base still needs space; rotating the canopy requires a clear path around it. The wheels do not make an open umbrella safe to move in windy weather.
The manual requires a flat, steady surface and says to close the canopy when wind exceeds 3 Beaufort. Treat that as a closure instruction, not evidence that this umbrella has been tested safe at every lower wind speed. Costway’s standard one-year home-use warranty applies to qualifying Costway.com purchases and excludes damage from misuse, negligence and other listed causes.
What to check before ordering
- Count the base parts. “Cross base included” usually identifies the metal support frame. It does not establish that ballast plates, reservoirs or sandbags are included. Look for the exact weighted-base system in the selected model’s contents and manual.
- Budget for ballast and assembly. An included reservoir still needs filling. Use that model’s materials, weight and assembly sequence; do not substitute a generic bag of sand or borrow another umbrella’s numbers. Position the base before filling where the instructions allow.
- Measure the whole installation. Allow room for the base, curved support, fully opened canopy and its rotation or tilt. Check head clearance and nearby walls, roof edges, trees, doors and lights. Neither manual establishes a universal clearance distance for every patio.
- Keep the support system intact. Attach the umbrella to its supplied base as shown, on a level, stable surface. Deck fastening, drilling or replacement anchors need a manufacturer-approved arrangement for that model; a cross frame alone is not adequate ballast.
- Plan to close it. Close and secure the canopy when unattended and before bad weather. A vented top and heavy base do not establish storm resistance. Follow the supplied storage instructions, including protection from freezing conditions where water remains in the system.
Our verdict
Start with the Grand Patio 11FT round Champagne if you want the crank-operated curved-arm package and can accommodate its specified ballast. Pick the Costway OP70377 for its pedal rotation and manufacturer-documented reservoir base. Before paying, match the selected size, color and included base to the listing and manual, then compare the total cost with ballast and any cover you need.
Frequently asked questions
Does “base included” mean the umbrella is ready to use?
No. Both picks include fillable base systems, but you must supply the required ballast and assemble the umbrella as instructed. A listing that includes only a metal cross base may still require separately purchased weights.
How much weight does an 11-foot cantilever umbrella need?
Use the instructions for the exact umbrella and base. The selected Grand Patio listing specifies 330 lb of sand plus 44 lb of water. Costway OP70377 lists 220 lb with water or 330 lb with sand and water. These are model-specific figures, not a universal minimum.
Is an 11-foot round umbrella the same size as an 11-foot square one?
No. The two picks here use an 11-foot nominal round canopy dimension. A square canopy has a different footprint, and the actual shade beneath either shape changes with the sun’s position.
Can I leave a cantilever umbrella open in wind?
Do not rely on a heavy base or canopy vent as a wind rating. Follow the exact manual, close the umbrella when unattended and before bad weather, and secure it as instructed. Costway OP70377 specifically directs closure above 3 Beaufort; that is not a promise of safety below that threshold.
Can I put one of these umbrellas on a deck?
Check that the deck can support the assembled umbrella, its filled base and the people and furniture around it. Allow space for the canopy’s full movement and keep the base level. If structural capacity or a fastening arrangement is uncertain, get appropriate advice before installation and use only a mounting method the umbrella manufacturer approves.
