Complete Guide to Stainless Steel Commercial Sinks

Choosing the right commercial sink is one of the most important decisions when outfitting a professional kitchen. Commercial sinks must withstand continuous use, comply with health regulations, and fit efficiently into your workflow. This guide covers everything you need to know about selecting the right stainless steel sink for your business.

Types of Commercial Sinks

Commercial kitchens typically require several types of sinks for different purposes:

  • Single Bowl Sinks: Ideal for smaller kitchens or as dedicated hand-wash stations. Available in sizes from 400mm to 1000mm widths. View single bowl sinks
  • Double Bowl Sinks: The most common configuration for commercial kitchens, allowing simultaneous washing and rinsing. Available in sizes from 1000mm to 1600mm. View double bowl sinks
  • Dishwasher Sink Units: Integrated sink and drainer combinations designed to work with commercial dishwashers. View dishwasher sink units
  • Hand Wash Basins: Dedicated hand-washing stations required by health codes in most jurisdictions. View hand wash basins

Material Grade Matters

All commercial sinks should be made from 304-grade stainless steel (18/8) for food contact surfaces. This grade offers superior corrosion resistance against food acids, cleaning chemicals, and continuous moisture exposure. Lower grades like 430 are not suitable for wet commercial kitchen environments.

Certification Requirements

Depending on your location, commercial sinks may need specific certifications:

  • WRAS Approval (UK): Required for all water fittings in the UK market. Xinhuili Metal offers WRAS-approved sink models.
  • EC 1935/2004 (EU): European regulation for materials intended for food contact.
  • CE Marking: Required for certain product categories sold in the European Economic Area.

Size and Configuration Guide

When selecting sink dimensions, consider the largest sheet pan or pot that needs to fit in the basin. Standard commercial sink bowls range from 400mm x 400mm up to 800mm x 600mm or larger. Bowl depth typically ranges from 300mm to 500mm. The drainer or platform area should accommodate your dish racks or drying trays.

Xinhuili Metal offers a wide range of commercial sinks in various sizes and configurations, all manufactured from premium 304 stainless steel with appropriate certifications for international markets. Browse our complete sink collection.
