Tangkula Patio Umbrella Base 4-Piece Octagon 41" x 41" — 350 lb Capacity, Water & Sand Fillable, Weather-Resistant

Tangkula's 4-piece octagon umbrella base provides a heavy, weather-resistant foundation that can reach up to 350 lb when filled, stabilizing cantilever and offset patio umbrellas. This umbrella base is a four-plate system molded from durable PE plastic that resists sun and rain exposure while staying simple to assemble and store. The plates interlock into an octagonal footprint measuring 41" x 41", and each section includes an easy-fill spout and built-in handle so you can add wet sand or water quickly and move the base when needed. With a net weight of 22 lb empty and a filled maximum of about 350 lb, it’s designed to give large outdoor umbrellas the ballast they need without expensive installation.

How does this base hold a large cantilever or offset umbrella steady?

The design spreads weight across four stacked plates to create a low, stable footprint beneath your umbrella. Filling each plate with wet sand raises the overall mass to resist tipping and shifting from gusts.

• Four separate plates lock together to form a single 41" x 41" base.
• 350 lb filled weight (wet sand) for strong wind resistance.
• Cross-height adapter and screws secure the umbrella pole tightly.

Is it easy to fill, assemble, and move when needed?

Yes—the Tangkula base is built for straightforward setup and later relocation. Each plate has a pour spout that prevents spills while filling and a molded handle for lifting one section at a time.

• Four easy-fill spouts allow quick sand or water filling without mess.
• Built-in handles on each plate aid transport and storage when empty.
• Simple slot-and-connector assembly requires no special tools.

Will this base withstand outdoor exposure and require much maintenance?

Manufactured from weather-resistant PE using an advanced blow-molding process, the base resists fading, cracking, and general UV degradation. The textured black finish is low-maintenance—wipe clean as needed and store plates dry in winter to prolong life.

• Durable PE construction resists sun and rain damage.
• Black textured surface hides dirt and is easy to clean.
• Disassemble for compact winter storage to further extend longevity.

What are the dimensions and compatibility details I should check?

The assembled footprint is 41" x 41" and 5.5" tall, while each plate measures 28.5" x 18" x 5.5". The base is intended for cantilever and offset umbrellas where a bulky ground anchor is either impractical or undesired; confirm pole adapter size and umbrella pole dimensions before purchase.

• Overall assembled size: 41" x 41" x 5.5" (L x W x H).
• Each plate size: 28.5" x 18" x 5.5"; net empty weight 22 lb.
• Holds up to ~350 lb when plates are filled with wet sand.

Who is this for? This Tangkula octagon umbrella base is best for homeowners and outdoor designers who need a portable, heavy-duty ballast for large cantilever or offset umbrellas without permanent installation. It’s a practical choice for patios, poolside lounges, garden seating areas, and rental properties where a stable, low-profile base is required. If you want a weather-resistant, easy-to-fill solution that combines high filled weight with simple assembly and discreet styling, this base fits those needs.
