Home Zone Living 40lb Half Round Fillable Patio Umbrella Base Stand, 18in, Black

Half-round patio umbrella base

The Home Zone Living base weighs 40lb when filled with water or sand and measures 18in across. Its half-round shape lets it sit flush against a wall or window while supporting umbrellas from 6 to 10ft in diameter. The reinforced HDPE shell resists UV exposure and outdoor weather. An adjustable knob secures poles up to 1.9in (48mm) thick.

Stability under sustained wind load

When filled to the 16L (4.2 gallon) capacity the base reaches its full 40lb mass, providing steady ballast for daily use on decks, lawns or by the pool. The HDPE construction does not crack or fade after prolonged sun exposure. Empty weight is low enough to move the stand by hand before filling. The knob maintains grip on the pole through repeated gust cycles.

Practical limits of the pole interface

The clamping knob accepts poles up to 1.9in (48mm) only; larger commercial poles will not fit. Maximum umbrella span is 10ft, so wider canopies need a heavier or differently shaped base. The half-round footprint saves space against structures but offers less leverage than a full circle of equal weight. Buyers needing to secure cantilever or offset umbrellas should look for a base designed for that mounting style.
