Three capacities cover almost every order we quote for collapsible basins: 8 litres, 16 litres and 30 litres. The difference between them is not just volume. Each size changes who the customer is, what they do with it and where it sits in a shop.
Here is what each one is for, the measurements of a typical mid-size unit so you have a reference point, and a way to plan a range rather than picking sizes at random.
Key takeaways
- 8L suits one or two people and gift channels.
- 16L is the volume size in most markets and the safest single-SKU choice.
- 30L goes to catering, group cooking, pet washing and boat use.
- If you only carry one size, carry the 16L.
The three sizes side by side
| Capacity | Typical use | Lid options | Where it sells |
| 8L | Washing small batches, marinating, food prep for one or two | Standard or sealed | Gift sets, camping, small households |
| 16L | Everyday dishwashing, vegetable prep, marinating a whole chicken | Standard, sealed, airtight locking | General retail, kitchenware, outdoor |
| 30L | Group cooking, washing large quantities, pet bathing, boat galley | Standard or sealed | Catering, hardware, marine, pet |
The lid column matters more than buyers expect. Higher capacities usually ship with a simpler lid because a latch on a 30L basin full of water is hard to close with one hand.
A reference measurement
Numbers help more than descriptions. Our 16L collapsible prep box measures 51.2 x 41.1 x 18 cm open and 51.2 x 41.1 x 4.5 cm folded. In practice that means an open footprint slightly larger than a standard oven tray and a folded height about the same as a thick laptop.
| 16L prep box | Size |
| Open | 51.2 x 41.1 x 18 cm |
| Folded | 51.2 x 41.1 x 4.5 cm |
| Capacity | 16 L |
| Material | Food-grade PP and TPR |
If you need the same sheet for the 8L and 30L models for a planogram or a retail listing, ask us for the dimension PDF. It is the document buyers usually need when they compare our unit against a competing one.
Why 16L is the volume size
A 16L basin washes a full meal for four without being awkward to carry, and it fits a standard kitchen sink surround. That combination keeps it the single best-selling capacity in kitchen, camping and outdoor ranges. When a buyer tests a market with one SKU, this is the one to test with.
It is also the size where the add-ons work best. A cutting board or a colander insert in a 16L basin is usable. The same insert in an 8L basin turns it into a crowded tray.
Where 8L and 30L earn their shelf space
The 8L gets bought twice as often in pairs. It suits camping kits, campervan drawers and gift bundles where the basin is one item among several. It is the size that turns a BBQ prep set into a boxed product.
The 30L is bought by customers who already know why they need it: a caterer washing for a service, a household processing a large batch of vegetables, someone bathing a spaniel, or a boat owner who wants a tub that folds into a locker. It is rarely an impulse purchase, so it sells better through specification and pictures than through a crowded shelf.
Planning an assortment
- Single SKU test. 16L, one colour. Lowest risk, fastest feedback.
- Standard range. 8L and 16L in two colours. Covers household and gift.
- Full range. 8L, 16L and 30L. Add the 30L only if you sell into catering, pet or marine channels.
- Colour split. Put the brighter colour on the larger size. Large basins carry a bold colour better than small ones.
Frequently Asked Questions
How many people does a 16L basin serve?
A full meal for four, or a day of dishwashing for a family of four to five. Two people camping usually find the 8L enough.
Where does a folded basin fit?
A 16L folds to about 4.5 cm, so a drawer, a campervan locker or the gap beside a fridge. A 30L folds thicker because the footprint is larger, which is worth checking against your storage before ordering.
Do all three sizes use the same material?
Yes. Food-grade PP for the body and food-grade TPR for the folding wall, rated -20 °C to 120 °C across the range.
Can I order a mixed carton of sizes?
MOQ is counted per model, so a mixed carton means meeting the minimum for each size you include. It is common for a first order and straightforward to arrange.
Bottom line
Pick the capacity by matching it to a job, not by picking the middle number. The 8L is a kit size, the 16L is the everyday size, and the 30L is a working size. Start with the 16L unless your channel already tells you otherwise.
All three are in production: the 8L collapsible BBQ prep set, the 16L collapsible prep box and the 30L collapsible prep tub. Ask us for the dimension sheet or a sample of each.
