The SAMMART 19L tub is an injection-molded utility item designed for vertical storage efficiency. The rim and base are made from BPA-free Polypropylene (PP) to provide rigid geometry, while the "accordion" walls are composed of Thermoplastic Elastomer (TPE). This combination allows the tub to collapse to approximately 2 inches in height, making it a practical fit for 18-inch deep cabinetry or under-sink storage. The dual-handle design helps distribute weight more evenly than single-handle alternatives during transport.
Specifications indicate a 19L (5 gallon) capacity. While the materials are safe for food-grade ice or produce soaking, tests show that filling the tub to the brim with water can cause the flexible walls to bow outward. For long-term use with liquids, maintaining a 75% fill volume is a practical way to help prevent material fatigue. The TPE walls are calibrated for over 10,000 collapse cycles, though storing the unit in temperatures exceeding 113°F should be avoided to help maintain structural integrity.
- The rigid base helps prevent tipping even when the tub is only partially expanded.
- Emptying the tub requires manual tipping as there is no integrated drainage plug.
- Avoid using boiling water, as high heat can potentially warp the elastomer segments.
This tub is a helpful tool for various household tasks, from laundry to car washing. Its ability to fold flat ensures it doesn't take up unnecessary floor space when the job is done.
If you find the 19L size too large for your needs, the SAMMART 9.2L variant offers a more compact footprint with the same folding technology.
