The Chem-Tainer 25 Gallon Plastic Portable Utility Tank is a flat-bottom, polyethylene utility tank that holds 25 gallons in a compact 17-by-24-inch footprint, standing 19 inches tall. Full of water it weighs about 208 pounds, light enough to set on a bench, truck bed, or trailer deck without a forklift. That combination is exactly why it turns up in so many "utility tank" and "25 gallon tank" searches: it is the size people reach for when they need real storage without committing to a large vertical tank.
Will it work for your job?
This is a 25-gallon flat-bottom utility tank molded from polyethylene, measuring 19 in high by 17 in wide by 24 in long with a 17.0 x 24.0-inch footprint. The flat bottom keeps it stable on any level surface, and the rectangular shape stores efficiently against a wall or in a corner. The tank carries a 1.5 specific gravity rating, meaning it is rated to hold contents up to 1.5 times the density of water. For water and similar light liquids that gives you wide margin, and 1.5 is the top of the Chem-Tainer utility line, so the real limit for any given liquid is chemical resistance, not the weight rating. One planning note: this listing specifies no pre-molded outlet, fitting, or gasket, so plan your plumbing around what the technical drawing on this page shows rather than assuming a factory outlet.
Sizing and weight
Use the listed weights to plan your support, and size to the higher number. Filled with water the tank runs about 208 pounds, but it is rated to carry up to 313 pounds of contents. Build your bench, shelf, or vehicle deck to hold the 313-pound maximum rated contents weight plus the tank itself, not the 208-pound water figure, because the day you switch to a denser liquid you will not re-read this page. If you are not certain this is the right capacity, run the numbers in our Tank Sizing Calculator or read the Tank Sizing Guide before you buy. Dimensions and any molded fitting locations are shown on the technical drawing on this page.
The mistake to avoid
The common error with a tank like this is treating the 1.5 specific gravity rating as a green light for any liquid. The rating speaks to weight-carrying capacity, not chemical resistance, and this listing carries no chemical-compatibility data. If you intend to store anything other than water, do not assume compatibility from the SG number alone: confirm the specific chemical against the manufacturer's chemical-resistance chart first, and call us if you want help. For outdoor and cold-climate placement, our guide to reservoir tank design and freeze protection covers keeping stored water usable through winter, and for grey-water or rainwater capture the water-reuse topology guide shows where a portable tank like this fits in a reuse train. For portable farm-fleet use, our guide on portable utility tanks and DOT classification walks through how these tanks are handled on the road.
This tank ships LTL freight, quoted live to your ZIP code from the nearest stocking plant. We stock it in both Marked Tree, AR and Merced, CA, so a buyer west of the Rockies ships from Merced and a central or eastern buyer ships from Marked Tree, which shortens the LTL distance versus a single-origin source.
