STOCK LINE
A single bowl undermount kitchen sink to stock
Fifty pieces is the entry quantity for S3018, a 30 inch single bowl in SUS304. It carries our Most Popular tag, and it is the under mount stainless steel sink to start a distributor range with.
One uninterrupted bowl
No divider, so the specification has one bowl to check and one drain location to confirm.
Small-radius corners
Small-radius corners maximize basin space and stay easy to wipe down, unlike sharp zero-radius wells.
10 inch depth
Every unit is 10 inches deep, 254 mm, so one depth figure goes on the schedule.
SUS304, 18 gauge
Steel is 1.2 mm SUS304 with a brushed stainless finish, the same on every unit.
FIT DATA
30 by 18 inch cutout and cabinet check
S3018 measures 30 by 18 by 10 inches, or 762 by 457 by 254 mm. It is tagged for sink bases from 30 to 32 inches wide.

Measure the clear inside width of the base unit and compare it with 30 inches, as you would for any of our kitchen sinks. Side panels and face frames reduce the space a sink can use.
Eighteen inches front to back leaves deck room behind the bowl for a faucet. Check the cabinet depth against the 10 inch bowl before the countertop is cut.
Ask the fabricator to confirm the cutout edge against the drawing, because the reveal is set on site and not by the sink.
APPLICATIONS
Single bowl kitchen sink for volume projects
Distributor and project orders often want one single bowl kitchen sink that every unit shares, and undermount kitchen sinks suit that brief. A single bowl removes the question of bowl split, so the specification stays short and the order list is easy to audit when cartons arrive.
Stone fabricators cut the countertop to the bowl opening, and the undermount rim leaves a clean counter edge. A single 30 inch template can repeat unit after unit.
Where a project needs a divided bowl, our double bowl undermount kitchen sinks uses the same steel and finish, so a mixed scheme looks consistent across kitchens.
WIDTH CHOICE
Where a 30 inch body wins over longer sinks
Longer single bowls give more room across the bowl but need a wider cabinet. S3018 is the 30 inch option for base units at the smaller end of the range.
The 30 to 32 inch width tag shows the span of sink bases it is made for. Buyers with mixed cabinet widths can check which kitchens fall inside that span.
If a kitchen needs a different bowl count, ask for a double bowl code in the same finish rather than a different steel.
If the cabinet is not a standard 30 inch run, send its drawing with the quantity and we confirm the options before the quotation.
SPEC WRITING
How to write the S3018 line in a specification
Name the model code, the SUS304 material and the 18 gauge thickness in one line. Add the brushed stainless finish and the undermount mounting so the schedule reads the same to the purchaser and the installer.
Attach the drawing to the line and quote the 10 inch depth on it. Installers use that figure to check the trap and disposer clearance before they plumb the sink.
Send the model code and quantity with the drawing request, and we return the drawing against the same line.
For a phased project, repeat the same code on every line. One model code, one material line and one drawing keep each delivery checkable against the first.
CERT & DRAWINGS
Certification and paperwork for S3018
Ask for the certificate details that match S3018 and your destination market.
S3018 is cUPC listed. Volume changes the delivery schedule rather than the paperwork, so give us the destination market and total quantity with the first enquiry.
The spec sheet and the dimensioned drawing are issued against S3018 on request. Both give a cabinet maker and a stone fabricator what they need to start, and both can go into the submittal pack.
MOQ & LEAD TIME
