The Chem-Tainer 26 Gallon PE Rectangular Open Top Tank is a compact polyethylene vessel built for batch work, parts soaking, mixing stations, and small-volume water handling where an open top keeps loading, stirring, and manual access simple. Filled, this rectangular open top tank holds roughly 217 pounds of water, so it sits comfortably on a bench, shelf, or floor stand without the structural demands of a large bulk tank.
At a glance: 26 gallons · ~217 lb full of water · atmospheric open top, gravity fill only · no installed fittings · ships LTL from Delano, MN.
Will it work for your application?
This is a rectangular open top tank molded from polyethylene by Chem-Tainer. The open top design suits work where you pour in, scoop out, or reach inside by hand: rinse stations, parts washing, dunk tanks, seed soaking, small water reservoirs, and aggregation catch basins. Because the footprint is rectangular rather than round, it nests against walls and into corners more efficiently than a cylindrical tank, which matters when floor space is tight. Plan your support surface around the full water weight of about 217 pounds; a flat, level, fully supported base keeps the walls from bowing and the tank stable in service. If you are weighing this size against other capacities, the Tank Sizing Calculator and Tank Sizing Guide help you confirm the right volume before you commit.
What to check before you buy
The most common mistake with an open top tank is treating it like a pressurized or sealed vessel. This is an atmospheric, gravity-fill container with no fittings installed on this model, so any drain, outlet, or plumbing is something you add yourself. The clean compatibility path is to source an aftermarket bulkhead fitting with a gasket sized to the wall thickness, then drill and seal it on site rather than expecting a pre-installed port. Confirm your liquid load against the 26-gallon capacity and the 217-pound full water weight, and confirm exterior dimensions with us at 866-418-1777 before ordering so the footprint fits your bench or corner. For setting a stable foundation even under a smaller tank, the concrete pad and base support guide covers how to keep the base flat and fully supported.
Where it fits in a water system
A small rectangular open top tank like this one often serves as a staging or transfer point inside a larger water handling setup, whether that is a rainwater or grey-water reuse train or a simple rinse-and-refill bench operation. If you are designing storage around water reuse or aggregation, the guide on industrial water reuse tank topology shows how small open-top vessels pair with larger bulk storage.
