Ware-wash sink

Gives jugs, portafilters, blender jars, brewing vessels and utensils somewhere to be properly washed, rather than rinsed at a tap and put back.

Washing is a sequence, not an event, and the fixture exists to make the sequence physically possible without the stages crossing. Soil is removed with detergent and mechanical action; the detergent is then rinsed away, because most sanitising chemistry is deactivated by the detergent it meets; and only then does the sanitising step get clean, rinsed items to work on, for whatever contact time its own label requires. A single bowl forces those stages to share one volume of water that gets progressively dirtier and progressively more contaminated with detergent, which is why a multi-compartment arrangement exists at all — it is the sequence made into furniture. Two mechanisms decide whether it works in a bar specifically. The first is DRAINING SPACE: an item that comes out of the final stage and is towelled dry has just been re-inoculated by the towel, so there has to be somewhere for a full service's worth of items to air-dry, and that space is always the thing that gets deleted from a small bar. The second is that a bar's soil is unusual — milk protein and fat, coffee oils, sugar and syrup — and each of those responds to a different chemistry and a different temperature, which is why one all-purpose detergent used cold is the most common reason a bar's jugs smell despite being washed daily. WHAT IS NOT STATED HERE, DELIBERATELY: how many compartments a given site requires, whether a mechanical warewasher may substitute for any of them, which sanitising method is acceptable, and every concentration, temperature and contact time involved. Those are set by the local food-safety authority and by the chemical manufacturer's own label, and they are the two authorities that govern — not a platform, and not a supplier's sales sheet.

• Confirm the required arrangement in writing with the local food-safety authority before the joinery is drawn — how many compartments, whether a mechanical warewasher may substitute for any of them, and what sanitising method is acceptable. This is not a design preference and it cannot be resolved from a catalogue.
• Size the bowls from the largest vessel on your own equipment schedule, then check it physically. A blender jar or a brewer server that does not fit is an item that stops being washed properly within a fortnight, and nobody will report it.
• Buy draining space at the same time as bowls, and buy more of it than looks necessary. Air-drying is part of the process; towel-drying undoes the final stage. A rack that holds one service's worth of items is the difference between a written procedure and a performed one.
• Give the bar a rinse point at the station so that the hand-wash basin does not become one. This is the most reliable way to protect the dedication of the hand-wash basin, and it is cheaper than any amount of reminding.
• Take the detergent and sanitiser decisions from the soil you actually generate — milk protein and fat, coffee oil, sugar — and follow the manufacturer's label for every dilution, temperature and contact time. The label governs; a supplier's verbal guidance and a remembered figure do not.
• Plan where dirty items are set down before washing and where clean items go afterwards, as two different surfaces. A single surface used for both is a cross-contact route that no amount of washing in between corrects, and it appears on no equipment list.
• Decide who washes and when, at design stage, because it determines the size. A bar that washes continuously through service needs less capacity and more reach; a bar that washes at close needs somewhere to stack a whole shift's items without blocking the station.
• If a mechanical warewasher is specified, treat its own cleaning cycle and its verification as part of the purchase. A machine that runs cool or with a spent chemical looks exactly like a machine that is working, which is the same silent-failure shape as the hand-wash basin with no soap.
