The 250 Gallon Doorway Water Tank (N-42337) from Norwesco solves a problem other tanks this size cannot: moving 250 gallons of storage through a standard doorway. At 29 inches wide, it clears typical residential and commercial door frames, then sits in a basement, utility room, or interior space where a round vertical tank would never go. Full dimensions are 29" wide x 62" long x 44" tall, so the name's "29 x 44" describes the front face, not the footprint - plan for the full 62-inch length when you size the room and the path in. It is molded from polyethylene with a 1.5 specific gravity rating, so it handles water and many heavier liquids alike.
Will it work for your install?
The footprint is 29.0 by 62.0 inches. Filled with water, the tank carries 2,085 pounds; the structure is rated to a maximum contents weight of 3,128 pounds. That ceiling matters for two reasons. First, the floor under the tank must support over a ton in a concentrated footprint - verify joist or slab capacity for 3,128 pounds before any upper-floor placement. Second, the gap between 2,085 lb of water and the 3,128 lb rating is real headroom for liquids heavier than water, up to the 1.5 SG limit (confirm your fluid's specific gravity x 250 gallons x 8.34 stays under 3,128 lb). If you are weighing capacity against available space, the Tank Sizing Calculator and Tank Sizing Guide walk through volume, weight, and clearance together.
Doorway clearance is the detail people miss
The mistake on a doorway tank is ordering on volume alone and treating it like any other 250-gallon unit. Measure your narrowest doorway, hallway turn, and stairwell first. This unit is sized at 29 inches across to clear standard door frames, but a tight corner or a low header can still stop it. If 29 inches does not fit your opening, there is also a 25-inch-wide version of this tank; all three are covered in our buyer's guides for the 29" x 44" white, 29" x 44" natural white, and 25" x 54" white models. For rural fire-water and reservoir setups where an interior tank feeds a private system, the fire-water reservoir design guide covers sizing discipline and freeze protection for cold-climate service.
