SUS304 Small Single Bowl Undermount Sink
The bowl for the 400 mm cabinet nobody makes a sink for
What This Product Is And Who It Is For
A compact square single bowl undermount sink in SUS304 stainless steel, deeper than it is wide.
It is specified for narrow base units, island prep points, bar stations and utility corners where a standard bowl will not go.
Depth is used instead of width, so the bowl still holds a stock pot.
Why Buyers Specify It
Fits where nothing else does
A short, square bowl opens up 400 and 450 mm cabinets that stock sinks cannot serve.
Depth instead of width
A deep bowl in a small footprint still takes a tall pan or a stock pot.
Second sink on an island
Gives a prep or bar point without losing island storage.
Same finish as the main sink
Brushed 304 lets a secondary bowl match the main sink in the same kitchen.
What It Fixes In A Buying Programme
Narrow cabinets have no sink option
This bowl is sized for them.
Small bowls are too shallow to be useful
Depth is used to recover capacity.
Secondary sinks do not match the main one
Same steel, same brushed finish.

Materials
SUS304 is the Japanese designation for the same austenitic grade sold as 304 — the grade to use where water quality varies.
Mounting hardware supplied to suit the worktop material.

- Bowl footprint to the cabinet width
- Depth to the plumbing available
- Drain position
- Topmount flange instead of undermount
How It Is Made
Cut the blank
A small bowl still starts from a developed flat pattern.
Form and fold
The square bowl is formed and the walls folded to the specified depth.
Weld and dress
Corners are welded and dressed so the small internal radius stays clean.
Brush
The interior is brushed in one direction and the flange is cleaned up.
Quality Control
- Bowl depth and opening are measured against the order drawing.
- Water test at the drain seat on every bowl.
- Internal corners are checked for polish continuity — small radii show defects most.

Use Guide
Step 1
Check the waste trap will fit the shallow cabinet before ordering the deepest bowl.
Step 2
Use a bowl grid if it will take pans regularly.
Step 3
Keep the drain clear — small bowls block faster.
Step 4
Wipe dry after use.
SUS304 Small Single Bowl Undermount Sink — Frequently Asked Questions
Is SUS304 the same as 304?
Yes. SUS304 is the JIS designation; the composition is the same austenitic 18/8 grade.
Can it be topmounted?
Yes — we can add a flange. Say so before production because the blank size changes.
What is the smallest bowl you make?
Small bowls are limited by the waste fitting more than by the steel. Send the cabinet width and the trap you plan to use.
