Choosing the right ice tray comes down to five things: the shape of the ice, the material of the tray, the cube size, whether it has a lid, and what you’ll actually use it for. Match those to your drinking and cooking habits and you’ll buy once instead of twice — a slow-melting large cube for whiskey, standard cubes for everyday highballs, or mini cubes for shakes and smoothies.
That sounds simple, but the sheer number of options on the market makes it anything but. A single Amazon search for heavy duty ice cube trays returns over 50,000 results, ranging from £6 silicone moulds to multi-tray systems with lids and bins (Amazon.co.uk). This guide cuts through the noise with the questions that actually matter.
Key takeaways
- Shape drives melt rate. Spheres melt slowest, large cubes are close behind, mini cubes chill fastest but water down drinks quickly, according to ice mould specialists at Küb (Küb).
- Silicone with LFGB or BPA-free certification is the most common and practical material for home freezers, with easy-release flexibility.
- A lid is worth having. Spill-resistant lids protect ice from freezer odours and let you stack trays.
- Buy for your use case: whiskey sippers want large cubes or spheres, cocktail makers want standard or mini cubes, batch cookers want trays for broth and sauce.
- Check cavity count and freezer space before you buy — a 64-piece set is great value only if you have room for it.
Why does ice shape matter so much?
Shape is the single most important variable, because it determines how quickly ice melts — and melt rate determines dilution. That’s the core argument in Küb’s ice mould buying guide, and it’s a useful framework for every purchase (Küb). Here’s how the main formats compare:
- Sphere: The slowest-melting shape, best for whiskey, bourbon and any drink you’ll sip on the rocks for 30 minutes or more.
- Large cube: Melts slightly faster than a sphere but sits flat and looks deliberate in a rocks glass — ideal for Old Fashioneds and stirred cocktails.
- Standard cube: The all-rounder. Chills a highball quickly without wrecking a mixed drink, and suits most everyday glasses.
- Mini cube: Fast melt but a high chill rate, which makes it the natural choice for shaken cocktails and blended drinks.
- Novelty shapes: Skulls, bears, tropical motifs — slower than small cubes but faster than spheres. Fun for parties and gifting rather than serious dilution control.

Which material should you pick?
Walk down the ice tray aisle (virtual or otherwise) and you’ll see hard plastic, soft silicone, and hybrids of the two. Each has trade-offs.
Silicone
Flexible silicone is the dominant material in current UK bestseller lists, appearing in products like the JRISBO 4-pack, the KEPLIN 2-pack and the Ram 4-pack silicone sets (OneClearWinner, October 2026) (OneClearWinner). Silicone’s flexibility is why these products are marketed as easy-release, and it copes with freezing liquids beyond water.
Two certifications to look for on the listing: BPA-free and LFGB. LFGB is the stricter German food-contact standard, and several leading UK trays (JRISBO, KEPLIN) advertise both. If certification isn’t stated, treat that as a question to ask the seller before buying.
Hard plastic
Traditional rigid plastic trays are cheap and stack neatly, though silicone’s easy-release and durable qualities are a big part of why it dominates current bestseller lists (OneClearWinner). If you go this route, look for listings that state food-grade or BPA-free materials.
Silicone with a lid and bin
Hybrid systems — such as the PHINOX 64-piece tray with lid, bin and scoop, or the 4-pack small stackable silicone trays with lids and bins on the OneClearWinner list — combine the tray with storage. You freeze, pop the lid on, and keep a supply of ice ready in the included bin. Great for households that go through a lot of ice in one evening.
What size and capacity do you actually need?
Size questions come in two flavours: the size of each cube, and how many the tray makes.
Cube size
Standard cubes around 2–3 cm suit most drinks. For large-format ice, products like the iNeibo silicone large ice cube tray make six 2-inch (roughly 5 cm) cubes and are marketed for whiskey and bar drinks — it’s one of Amazon’s top 10 best-selling brands in its category, with a 4.6-star rating from around 1,700 reviews at roughly £6.38 (Amazon.co.uk) (Amazon.co.uk). Do check that large cubes will actually fit the glasses you use before ordering.
Cavity count
Trays on the current UK market range widely: the Sinnsally set makes 15 large squares per tray across three trays, while multi-pack sets like the JRISBO (four trays) or the 64-piece PHINOX system suit bigger households (OneClearWinner). A simple rule: one tray per two to three ice-drinking adults for a typical evening, plus one backup. And measure your freezer shelf — stackable designs help, which is why “stackable” appears in so many of the leading UK listings.
Do you really need a lid?
In a word: usually, yes. Lids on modern trays serve three jobs. They stop spills when you carry a full, sloshing tray to the freezer; they shield ice from picking up freezer odours (onions and ice cubes are poor neighbours); and they enable stacking, which matters in a crowded UK freezer.
Most current bestsellers have them — the KEPLIN, JRISBO, Ram and PHINOX sets all feature non-spill or spill-resistant lids (OneClearWinner). One general point to consider when comparing sets: lid design varies, and many bestseller listings highlight flexible or removable lids as a feature, so check the lid construction before buying. If the lid is removable, you can also use the base tray for freezing other things.
Which tray suits which use case?
Rather than choosing a tray in the abstract, start from what you’ll freeze and drink.
- Whiskey and spirits on the rocks: large cubes or spheres. For a deeper dive on the round option, see our best sphere ice moulds review.
- Cocktails and highballs: standard cubes, possibly in a multi-tray set so you never run dry mid-party.
- Shaken or blended drinks: mini cubes, which chill fast and blend easily (Küb).
- Batch cooking: you don’t need drink ice at all — you need trays for stock, wine, herbs in oil and coffee. Silicone bases with removable lids are ideal here; our guide on freezing broth and sauce cubes walks through it.
- Parties and entertaining: novelty shapes or a lidded system with a bin and scoop so guests can help themselves.
What should you check before buying? A quick checklist
- Material and certification: BPA-free as a minimum; LFGB if you want the stricter standard.
- Shape match: sphere or large cube for slow sipping, standard for everyday, mini for shaking (Küb).
- Lid: spill-resistant and removable beats fixed and flimsy.
- Cavity count vs freezer space: stackable designs earn their keep in small freezers.
- Cleaning: several UK sets, such as the Ram 4-pack, are dishwasher safe — check before you commit (OneClearWinner).
- Reviews at volume: a 4.6-star rating across 1,700+ reviews tells you more than any product description (Amazon.co.uk).
- Price per tray, not per set: multi-packs often work out cheaper, but only if you’ll use them all.

FAQ
Are silicone ice trays better than plastic?
For most home users, yes — silicone’s flexibility makes cubes far easier to release, and it handles both water and food freezing well. Rigid plastic is cheaper but cubes can stick and trays can crack. Look for BPA-free or LFGB certification whichever way you go.
What size ice cube is best for whiskey?
Large cubes around 2 inches (roughly 5 cm) are the popular choice for spirits, as bigger ice melts more slowly and dilutes the drink less over a long sip (Küb). Spheres melt slowest of all if you want maximum longevity.
Why does my ice taste like the freezer?
Exposed ice absorbs freezer odours over time. A lidded tray solves this — it’s one of the main reasons lids feature on nearly every leading UK tray (OneClearWinner). Also avoid storing ice next to strong-smelling foods, and use ice within a week or two for best flavour.
Can I freeze things other than water in an ice tray?
Absolutely. Broth, stock, wine, coffee, fruit purées, herbs in oil and baby food all freeze well in silicone trays, which is another point in silicone’s favour. Pop frozen cubes into a labelled freezer bag to free the tray up for the next batch.
How do I get cloudy ice clearer at home?
Cloudiness comes mainly from trapped air and impurities, which freeze last in the middle of the cube. Some clear-ice techniques, such as directional freezing, are widely discussed among drinks enthusiasts, though results vary at home — for most home drinks, a clean tray, filtered water and fresh ice make a bigger practical difference.
The bottom line
Choosing the right ice tray isn’t complicated once you frame it correctly: pick the shape for your drink, pick certified food-safe silicone, insist on a sensible lid, and buy the capacity your freezer can actually house. Do that and even a modest £6–£10 tray will outperform a drawer full of mismatched plastic.
If you mostly drink whiskey, start with a large-cube or sphere mould; if you’re freezing stocks and sauces, a lidded silicone multi-pack will earn its keep every week. And once you’ve got the tray sorted, the fun part begins — experimenting with what goes in it.
