Keeping bait in top condition is one of the most overlooked aspects of sea fishing. The WSB Fishing Cool Boxes — available in 5L and 9.4L — are purpose-built for UK shore and boat anglers.
Ask any experienced UK sea angler what separates a good session from a blank, and bait quality will come up every time. Fresh, firm bait stays on the hook better, releases more scent into the water, and simply catches more fish. Warm, soft, or partially defrosted bait is harder to present, falls off the hook, and is far less attractive to fish.
For anglers who use frozen bait — squid, mackerel, sandeel, black lug — keeping it in the right condition from freezer to hook is essential. That's where a good cool box makes all the difference. And the WSB Fishing Cool Boxes have been designed specifically with the shore and boat angler in mind.
WSB Tackle offer two sizes of cool box, covering everything from a quick solo session to a full day's fishing with plenty of bait:
The WSB 5 Litre Cool Box is the compact option — and at 27cm x 20cm x 17cm, it's small enough to slip into your tackle bag or sit neatly in your beach trolley without taking up too much space.
Don't let the size fool you though. This box will comfortably accommodate a couple of boxes of squid and several packets of frozen bait — more than enough for a typical shore fishing session of a few hours. The sealed foam insulation keeps contents cool for up to 9 hours, so your bait will still be in prime condition when you're casting your last rig of the session.
Key features:
At £14.99, it's also exceptional value — a small investment that will pay for itself many times over in better bait presentation and more fish on the bank.
The WSB 9.4 Litre Large Cool Box is the bigger sibling — measuring 35.5cm x 24.6cm x 26cm, it's designed for longer sessions, bigger bait requirements, or anglers who like to carry a variety of bait types.
The 9.4 litre capacity gives you room for several boxes of squid, multiple packets of frozen bait, and still space for ice packs to maintain temperature throughout the session. Like the 5 litre version, the sealed foam insulation keeps contents cool for up to 9 hours — more than enough for a full day's fishing.
Key features:
At £26.99, the large cool box is the go-to choice for full-day sessions, overnight fishing, or boat trips where you need to carry a substantial amount of bait.
Choosing between the two sizes comes down to how long you fish and how much bait you typically use:
If you're unsure, go for the larger size — you can always fill unused space with ice packs, and having more room is never a problem.
A good cool box is only as effective as how you use it. Here are a few tips to maximise bait freshness:
Pre-chill the box before use. Put a couple of ice packs in the cool box the night before your session. Starting with a cold box means the insulation works harder for longer once you add your bait.
Use proper ice packs, not loose ice. Loose ice melts and creates water that can damage bait packaging and make a mess. Reusable ice packs are cleaner, more effective, and can be refrozen after each session.
Don't open the lid unnecessarily. Every time you open the cool box, warm air gets in. Take out what you need for the next rig and close it again promptly.
Keep the box out of direct sunlight. Even the best insulation struggles against direct summer sun. Keep your cool box in the shade of your shelter or beach bag where possible.
Layer your bait. Put the bait you'll use last at the bottom and the bait you'll use first on top. This minimises how often you need to rummage through the box.
The WSB cool boxes aren't just for bait. Both sizes are equally useful for:
👉 WSB 5 Litre Cool Box — £14.99
👉 WSB 9.4 Litre Large Cool Box — £26.99
