Choosing the right commercial dishwasher or glasswasher comes down to matching the machine to your volume: how many covers you’re doing, how fast items need to be back in service, and whether your water supply and drainage can support the unit you want. Get those right and the rest – plates versus glasses, softening, chemical dosing – falls into place. This guide covers what actually matters when you’re buying, our top picks across the price range, and what you should realistically expect to pay.
How to choose a commercial dishwasher or glasswasher
The first decision is undercounter versus pass-through (or hood). Undercounter dishwashers and glasswashers sit under the bar or pot wash and suit lower-volume sites – cafés, small restaurants, community pubs – where a cycle every couple of minutes keeps up with demand. Pass-through and hood dishwashers are built for busier kitchens: baskets slide through on a track or under a hood, cycle times drop, and throughput goes up considerably. If you’re regularly backing up at the pot wash during service, that’s usually the sign you’ve outgrown an undercounter unit.
Beyond volume, check three practical things before you buy: water hardness, drainage, and power supply. Hard-water areas need a water softener – either built in (often listed as an integral or inbuilt softener) or fitted separately – to stop limescale wrecking heating elements and leaving marks on glassware. If your kitchen’s drain isn’t low enough for waste water to run away by gravity, you’ll need a break tank to store and pump it out instead. And larger dishwashers, especially pass-through models with chemical dosing pumps, often need a three-phase supply, so it’s worth checking your kitchen’s electrics can take it before you order.

How much does a commercial dishwasher cost?
Prices across our commercial dishwasher and glasswasher range span a huge gap, because the category covers everything from small accessories and signage right up to industrial machines. The very cheapest listed items, from around £23, are typically small parts rather than full machines – a genuine standalone unit realistically starts more like £1,750 and up. Around a quarter of the range sits under roughly £3,344, which covers smaller undercounter dishwashers and glasswashers for lower-volume sites. The median price across the category is around £5,480 – a fair benchmark for a solid mid-range frontloading dishwasher or premium glasswasher – and three-quarters of products come in under about £7,736, which covers most single-site kitchens comfortably. Above that, pass-through and specialist units with features like chemical dosing or exhaust heat recovery run into five figures, with the largest industrial models reaching around £43,486.
Frequently asked questions
Undercounter or pass-through dishwasher — which do I need?
Undercounter glasswashers and dishwashers suit lower-volume sites like cafés and bars. Pass-through models are built for higher-volume kitchens, with faster cycle times to keep pace with service.
How much does a commercial dishwasher or glasswasher cost?
It depends heavily on volume and features. Smaller undercounter units typically start from around £1,750-£3,344, a mid-range machine sits around the £5,480 mark, and higher-volume pass-through or premium models commonly run to £7,736 and beyond – with large industrial units reaching into the tens of thousands, up to around £43,486 at the very top end.
Do I need a water softener built in?
In hard-water areas, an integral water softener protects against limescale build-up on heating elements and glassware — worth checking whether it is built in or needs adding separately.
What is a break tank and do I need one?
A break tank stores and pumps waste water where a site’s drain height is not low enough for gravity drainage — relevant mainly for sites without a suitable existing drain position.
