Stable 20" Umbrella Base
This 20-inch round base holds 23 litres of water to anchor a patio umbrella against wind. It is made from HDPE and steel for all-weather durability. The self-filled design keeps outdoor shade steady on gardens, patios or similar surfaces.
Fits 38mm and 48mm Poles
The base accepts umbrella poles of 38 millimetre or 48 millimetre diameter without extra adapters. It replaces lighter stands that shift in gusts and removes the need for separate ballast bags. The jump is worthwhile when a freestanding umbrella must stay put through breezy conditions.
23-Litre Capacity and Portability
When filled, the unit weighs roughly 4.8 pounds plus the water mass, giving firm hold for standard market umbrellas. Empty, it is light enough to carry and store between seasons. It runs out of headroom for oversized cantilever models or poles outside the two stated diameters.

Questions about this item
What diameter pole fits the 20.0" Costway base?
The base accepts poles of 38 mm or 48 mm diameter, so match your umbrella pole to one of those two sizes before buying.
How do I install the base and what step is often missed?
Place the empty base, insert the umbrella pole into the correct sleeve, tighten the locking knob, then add 23 L of water through the fill cap — skipping the water makes the base only 4.8 lbs and unstable.
What maintenance will the HDPE and steel base need over time?
Rinse the HDPE shell periodically, check the steel pole sleeve for rust, tighten the locking knob each season, and drain the 23 L of water before freezing weather to prevent cracking.
