How to Use a BBQ Prep Tub: A Step-by-Step Guide from Prep to Cleanup

Quick answer: To use a BBQ prep tub:

1. Expand it to the height your cut needs.
2. Trim and season the meat on the built-in cutting board.
3. Add your marinade, lock the lid and refrigerate it on the bottom shelf.
4. Carry the sealed tub to the grill.
5. After cooking, wash it, dry it fully and fold it flat for storage.

One container handles the whole cook, from raw prep to slicing.

You bought a prep tub, or you're thinking about one, and you want to get the most out of it. This guide walks through the full workflow, from expanding the tub and trimming a brisket to marinating, transporting, slicing and cleanup. It also covers which height setting suits which cut, and the mistakes that shorten a tub's life.

If you're still deciding, start with what a prep tub is. The steps below assume a collapsible BBQ prep tub with a locking lid and a built-in cutting board.

How to Use a BBQ Prep Tub, Step by Step

Step 1: Trim on the built-in cutting board

Start with the tub collapsed or at its lowest setting so the cutting board sits at a comfortable working height. Trim fat caps, silver skin and loose edges right there. Juices and trimmings stay inside the walls instead of running across your counter. 

Step 2: Expand to the right height

Pull the walls up to the setting that fits your cut (see the height guide below). For dry rubs, a lower wall gives you room to work. For wet marinades or brines, go taller so the liquid covers more of the meat.

Step 3: Season or marinate

Apply your binder and rub, or pour in the marinade and turn the meat to coat it. Lay pieces flat in a single layer so every surface makes contact. Before the marinade touches raw meat, set aside a cup to use for basting later.

Step 4: Lock the lid and refrigerate

Snap the locking lid closed and slide the tub onto the bottom shelf of the fridge. Always marinate in the refrigerator, never on the counter, and keep your fridge at 40°F or below (Utah State University Extension). Flip the meat once halfway through for even flavor.

Step 5: Transport to the grill

Carry the sealed tub straight from the fridge to the smoker, the truck or the campsite. The lid keeps juices in, so there are no drips on the patio or in the car. Discard any used marinade instead of pouring it over cooked meat.

Step 6: Rest, slice and serve

Wash the tub, or use a second one, before cooked meat goes in. Never put cooked food back into a container that held raw meat. For a long rest, wrap big cuts in a resting blanket first, then slice over the tub so the juices are caught for serving.

Step 7: Switch to cooler mode

Once the meat is on the grill, a clean tub can hold ice and drinks or keep sides and salads cold until it's time to eat.

Step 8: Clean, dry and collapse

Wash it in hot, soapy water or the dishwasher with the walls fully expanded so the folds get clean. Let it dry completely before folding it flat. Trapped moisture in the creases leads to odors.

Which Height Setting and Size to Use

The Havenity tub has three height settings and expands to as much as 5.7" deep. Match the setting to the job:

Size: choose the 8 L tub for weeknight cooks of chicken, steaks and veggies. Choose the 16 L tub for full racks of ribs, pork shoulders and cookouts. For oversized cuts like a whole packer brisket, measure the meat first, or step up to the 30 L tub in the 3-pack.

6 Mistakes to Avoid with a Collapsible Prep Tub

1. Putting it in the oven or smoker. Prep tubs are for prep, storage and transport, not for cooking. Keep the tub away from direct heat.
2. Marinating on the counter. Bacteria multiply fastest between 40°F and 140°F. Marinate in the fridge, and don't leave raw meat out for more than 2 hours, or 1 hour above 90°F.
3. Reusing raw marinade as a sauce. Set some aside before it touches the meat, or bring used marinade to a full boil first.
4. Cutting along the folds. Do your knife work on the cutting board, not against the flexible walls, where a sharp blade can nick them.
5. Folding it while wet. Moisture trapped in the creases causes odors. Dry it fully before you collapse it.
6. Using one tub for raw and cooked food. Wash it between uses, or keep two tubs: one for raw meat, one for cooked food and sides.
