The Modular Systems SMS-H is a heavy-gauge stainless steel single mop sink for commercial kitchens, food-service venues, hospitality cleaning stations and back-of-house wash-up areas. Built from 1.2 mm SUS304 stainless steel with a fully welded, polished bowl, the SMS-H is engineered for daily mop-bucket fills, floor-mop rinsing and chemical-resistant cleaning workflows that would corrode lighter-gauge or coated sinks. Why operators choose the SMS-H 1.2 mm SUS304 (18/8) stainless steel — full food-service grade, corrosion-resistant against bleach, degreasers and floor chemicals Fully welded bowl, polished inside and out — no joins to harbour bacteria or trap residue 90 mm drain hole — handles dirty mop water with debris without backing up 520 × 515 × 800 mm footprint — fits standard 20 L mop buckets and sits under most low-set commercial taps Hairline finish — hides surface scratches from daily wear Health-code friendly — a dedicated mop sink separates floor-cleaning from food-prep wash, as required by most council inspectors Specifications Specification Value Brand Modular Systems Model SMS-H Type Single mop / cleaner's sink Material SUS304 (18/8) stainless steel Gauge 1.2 mm Finish Hairline Bowl construction Fully welded, polished inside and out Drain hole 90 mm Ø Tap / faucet Not included — order separately Product dimensions (W × D × H) 520 × 515 × 800 mm Packed dimensions (W × D × H) 570 × 660 × 570 mm Country of manufacture China Warranty 2 Years Parts Only Venue suitability Suited to commercial kitchens, restaurants, cafés, pubs and clubs, hotels, schools, childcare centres and any food-service venue that needs a dedicated wash station for mops, floor scrubbers and cleaning chemicals — separate from food-prep sinks. Most local council health inspectors require a dedicated mop sink in commercial food premises; the SMS-H satisfies that requirement. Installation notes The SMS-H ships as a freestanding unit at 800 mm working height. Plumbing connects to the 90 mm drain via standard waste fittings; a tap or rinsing spray is plumbed in separately at the wall (the unit doesn't include a tap). Position the sink with clearance for a 20 L mop bucket and consider a wall-mounted spray hose or pre-rinse tap for filling buckets quickly. Frequently asked questions Does the SMS-H come with a tap? No — the sink ships without a tap. Plumb in a separate wall-mounted commercial tap or pre-rinse spray. Most operators use a swan-neck mixer or pre-rinse spray so the spout sits high enough to clear a 20-litre mop bucket. Why do I need a separate mop sink — can't I use the kitchen sink? Most Australian council health inspectors require a dedicated mop sink in commercial food premises so floor-cleaning chemicals and dirty mop water don't enter food-prep sinks. Using a food-prep sink for mopping is a common audit failure. Will a standard 20 L mop bucket fit inside? Yes — the SMS-H bowl is sized to take a standard 20 L commercial mop bucket for filling. The 800 mm working height also lets you tip-empty buckets without lifting them onto a bench. How does 1.2 mm SUS304 compare to lighter gauges? 1.2 mm is heavy-gauge for sink construction — it resists denting, holds shape and handles years of daily use. Lighter 0.7 mm or 0.9 mm sheet is fine for under-bench shelving but flexes under weight when used as a sink basin. What's the warranty? 2 Years Parts Only against manufacturing defects (welding, finishing). The unit is otherwise mechanical with no moving parts to fail.
