Pure Garden Half Round Umbrella Base 34 lb Fillable Semicircle Stand — Black, Wall-Flush Space-Saving Design

The Pure Garden Half Round Umbrella Base is a 34 lb fillable, freestanding semicircle stand designed to hold half or wall-flush patio umbrellas securely while saving space on decks, balconies, and patios.

This compact umbrella base is built from high-density polyethylene with a powder-coated steel stem and dual tension screws, engineered to accept umbrella poles 1.5"–1.8" in diameter. Its flat back allows the stand to sit snug against a wall or railing so you get maximum shade with minimal footprint — especially useful where square footage is limited. With a top-fill hole, carry handle on the underside, and a simple assembly using the included Allen wrench, this stand is made for straightforward installation and seasonal repositioning.

How does this half-round base save space on small patios or balconies?

Because one side of the base is flat, it fits flush to walls and railings so the umbrella sits closer to the edge of the deck. This reduces the stand’s usable radius and frees up floor area for furniture or foot traffic.

• Semicircle design places umbrella against walls or railings
• Reduces obstruction compared with full-round bases
• Works well next to patio tables with umbrella holes for extra stability

How stable is the base in normal outdoor conditions?

The shell is molded from durable HDPE and designed to be filled with up to 34 pounds of play sand, which provides sufficient ballast for everyday use. For safety, it’s best to close the umbrella in strong gusts; the product performs best when used with a table or in sheltered spots.

• Max fill capacity: 34 lb of sand for ballast
• Recommended for sheltered or table-mounted umbrellas in winds under 10–15 MPH
• Steel stem with dual tension screws keeps poles 1.5"–1.8" secure

What is involved in setup and regular handling?

Assembly is minimal: insert the powder-coated steel stem and tighten the provided fasteners with the included Allen wrench. The top fill port and plug make adding ballast simple, and the integrated carry handle on the underside helps with moving the stand once filled.

• Includes Allen wrench for stem installation
• Top fill hole with plug for easy sand filling and sealing
• Built-in bottom handle for repositioning after filling

Will this base fit my umbrella pole and outdoor table setup?

This stand accepts poles between 1.5" and 1.8" in diameter and pairs well with patio tables that have umbrella holes to add stability. It’s optimized for half or wall-flush umbrellas rather than standalone oversized market umbrellas.

• Pole compatibility: 1.5"–1.8" diameter
• Ideal when used with patio tables featuring umbrella holes
• Stand dimensions: 19" L x 12" W x 15" H for space planning

Who this is for: Homeowners or renters with limited outdoor space who want reliable shade without a bulky base; people who use half or wall-flush umbrellas on decks, balconies, or next to patio tables; and anyone seeking a weather-resistant HDPE base that’s easy to fill, move, and store. If you need a heavy-duty freestanding anchor for very large umbrellas or constant high winds, consider a full-round, higher-capacity base instead.
