Drop-In Basin

A rectangular drop-in bowl for counters cut on site

The RSW is a rectangular drop-in bathroom basin in matte white solid surface, supplied as a bowl for installation into a prepared counter.

01 / MOUNT

Rim carried by the counter

The basin drops into a cut-out and the counter takes the weight, so the same bowl works with stone, timber or laminate tops.

02 / FORM

Rectangular bowl, plain rim

A straight-sided bowl lines up with a rectangular cut-out and keeps the setting-out simple for the fabricator.

Published references are RSW500 and RSW600. Integrated tops that avoid cutting the counter entirely are listed in the solid surface basin range.

Fit & Clearance

Cut-out size decides whether this basin fits

On drop-in basins the cut-out is the specification the fabricator actually uses.

Mount Drop-in
Shape Rectangular
Finish Matte White
References RSW500 / RSW600

Request the cut-out dimension for the exact reference and pass it to the counter fabricator in writing. RSW500 and RSW600 are not interchangeable once a counter is machined. Check the underside clearance for the trap before the cabinet interior is fixed.

Never scale a cut-out from a drawing. Use the published figure.

Construction & Finish

Solid surface bowl with a formed supporting rim

Both RSW widths are listed as solid surface with a matte white finish.

FORMED RIM

Rim is part of the bowl

The supporting edge is cast with the basin, so the load path from counter to bowl runs through one piece of material.

The visible result depends on the fabricator as much as on the basin. A clean cut-out and a thin sealant bead give a tight line, while an oversize cut leaves a gap no product can hide.

Agree the sealant colour with the counter supplier before installation.

Compliance

Documents supplied with RSW basins

DOC
Cut-out drawing per reference

Provided in the format your counter fabricator can work from, with the market noted on the file.

The published specification lists no certification mark, so nothing is claimed for RSW500 or RSW600. Name the destination market in the enquiry and we will confirm what documentation can be issued for the reference you buy.

Fabricators and installers usually want the cut-out drawing more than anything else. It is issued per reference with the quotation on request.

Procurement

Stocking two drop-in widths

Supplied wholesale to importers, distributors and counter fabricators.

Published MOQ 300 pcs
Standard Lead Time 30–45 days (typical)

Bowl size, rim width and drilling can be adapted for a private label drop-in line through the SANIKB OEM and ODM program. Both widths can usually run together when the finish is the same.

Include these details with the RFQ

  • Quantity per reference
  • Cut-out drawing required
  • Counter material and thickness
  • Waste and pop-up requirement
  • Overflow requirement
  • Destination port
  • Carton marking requirement

RSW500 and RSW600 are separate line items on the quotation.

FAQs

What material is this drop-in basin made from?

It is cast from solid surface, a non-porous resin and mineral stone composite with a matte white finish that resists stains and is repairable by sanding. See the full solid surface basin range for material specs and color matching.

How does this rectangular basin install?

The wide flat deck rim is engineered to drop into a countertop or vanity cutout from above, with a single center drain and no overflow. We supply CAD cutout templates for fabricators on request.

Can the size and dimensions be customized for a project?

Yes. As the manufacturer we offer OEM/ODM tooling and custom bowl dimensions and rim profiles, with low MOQ for hotel, builder and distributor projects. Request a quote.
