Eco-Series Basins have molded columns that transfer the weight of the statuary down to the ground below it. These columns can be filled with concrete creating pillars under heavy statuary. Four access doors (on 40" and larger) allow for multiple pumps, auto-fill, underwater lights or can be used as plant pockets. Roto-molded for superior strength. Ideal for use with concrete statuary, vases, rocks and fountains. 65 gallon capacity.
