The Benefits of Handmade Stainless Steel Sinks

What is a Handmade Sink?

Handmade sinks are welded, not pressed — crafted from premium stainless steel with thicker walls, sharper corners, and thoughtful finishes.

Key Benefits:

  • Durability– Thicker steel (2-3x pressed sinks) with seamless welds (no silicone sealing), certified for 15kg+ load capacity (SGS/BV tested).
  • Custom Design– Adjust dimensions (±5mm), create R5 corners (15% deeper basins), or integrate multi-tier layouts via 3D CAD files.
  • Flexibility– 10pcs trial orders with quick production, ideal for niche collections or premium OEM branding.
  • Premium SUS 304 stainless steel
  • R5 tight corners, more usable space
  • Custom sizes, depths, and configurations
  • Scratch & stain resistant
  • MOQ from 10 pcs with short lead times
  • Easy to clean & maintain

Turn Your Ideas Into a Real Handmade Sink

Customizing your stainless steel sink doesn’t need to be complicated. At Matrix®, we guide you through every step — from measuring your cabinet to choosing your mounting style and sink layout.

Measure Your Cabinet Space

Start by measuring the width and depth of your kitchen cabinet — this helps determine the right sink size and fit for your space.

Choose your preferred installation method

Stainless steel kitchen sinks have three common mounting options to fit different cabinets and countertop styles:

  • Top-Mount — Easy to install, with a visible edge resting on the countertop.
  • Under-Mount — Sits below the countertop for a seamless, clean-lined look.
  • Apron Front — Also known as farmhouse style, the exposed front adds character and ergonomic comfort.
Select the sink style

Choose from a wide range of bowl configurations — single, double, equal, or with accessories like drainboards — to match your kitchen’s flow.

How We Craft Handmade Sinks?

At Matrix®, we operate two dedicated workshops for handmade and pressed sinks, each with specialized lines and full in-house testing facilities in Zhongshan, China.

Our 85-person team — including 5 engineers and 1 designer — helps turn your ideas into precise, high-performance stainless steel sinks, with efficient turnaround and consistent quality.

Material Preparation & Laser Cutting

Premium SUS 304 stainless steel coils are selected and cut to specification. Precision laser cutting ensures clean edges and accurate dimensions for all sink components.

Bending & TIG Welding

Cut panels are folded into shape using industrial bending machines. Skilled technicians then use TIG welding to form seamless joints, creating the base structure of the sink.

Corner Finishing & Polishing

Each welded unit is hand-polished, with extra attention to the R-corners. This ensures a smooth finish that balances visual appeal with easy maintenance.

Final Surface Treatment

A surface coating is applied to improve corrosion resistance, reduce staining, and deliver the desired finish — whether satin, nano black, or brushed.

Handmade Stainless Steel Sinks: A Practical Buying Guide

At Matrix®, we specialize in designing and manufacturing premium handmade stainless steel sinks that combine durable craftsmanship with tailored aesthetics. Unlike mass-produced options, handmade sinks are TIG-welded from thick SUS304 stainless steel sheets and allow for custom sizing, layouts, and finishes.

Whether you’re outfitting a residential kitchen, luxury apartment, or premium hospitality project, Matrix handmade sinks are a durable and flexible solution—engineered for both function and form.

What Is a Handmade Stainless Steel Sink?

Handmade sinks are crafted by precision-cutting and TIG welding stainless steel plates—typically SUS304 grade, with thickness from 1.2mm to 1.5mm. This process eliminates the limitations of mold stamping used in pressed sinks, offering greater freedom in size, design, and finish.

Why Choose a Handmade Sink Over a Pressed Sink?
  • Pressed sinks use thin steel (often under 0.8mm) formed by molds—lower cost, but less durable.
  • Handmade sinks feature seamless welding, sharper R-corners, and allow for:
    • Custom basin depth
    • Integrated multi-level accessories
    • Special cutouts or oversized bowls
