FOUR LENGTHS

Square undermount bathroom sink: the SN029 size ladder

Design detail first: SN029A, at 400 × 360 mm, is the closest the series gets to a square undermount bathroom sink, and each larger model stretches the length while the width barely moves.

Length steps from 400 mm (15 3/4 in) on SN029A to 455 mm (18 in) on SN029B, 495 mm (19 1/2 in) on SN029C and 605 mm (23 3/4 in) on SN029D.

Width stays between 355 and 400 mm and overall height between 170 and 180 mm. That keeps one bowl character from a compact guest bath to a longer primary vanity.

If the bowl must read as a true square, specify SN029A. The longer models are rectangular in proportion.

SIZE TABLE

All four SN029 models, length × width × height

SN029A: 15 3/4 × 14 1/4 × 6 7/8 in (400 × 360 × 175 mm)
SN029B: 18 × 14 × 7 1/8 in (455 × 355 × 180 mm)
SN029C: 19 1/2 × 15 1/4 × 6 3/4 in (495 × 385 × 170 mm)
SN029D: 23 3/4 × 15 3/4 × 7 1/8 in (605 × 400 × 180 mm)
Drain: 1.8 in (45 mm) opening, 2.8 in (70 mm) reference
Mounting: Undermount
Material: Vitreous china ceramic
Finish: Glossy White
MOQ: 20 pcs

Each figure is the overall exterior size. The store offers the series as nominal 16, 18, 20 and 24 inch choices, matching SN029A to SN029D in order.

BEFORE ORDERING

Cutouts, drains and unbranded supply by model

A cutout for each size

Every model has its own cutout footprint. Matching cutout dimensions and mounting templates are provided on request for fabricators.

Overflow decides the drain

A basin without overflow takes a free-flow drain, one with overflow a standard pop-up drain. We confirm the setup for each model at quotation.

CAD cutout files

Spec sheets and CAD cutout files are available on request, useful for specification and listing work.

Unbranded supply

Private-label and own-brand programs can take unbranded product, with carton marking and packaging set per program.

MIXED SIZES

Mix the four sizes in one 20 ft container

MOQ: 20 pcs
Container: Mixed 1×20 ft accepted

MOQ is 20 pcs and a mixed 1×20 ft container is accepted, so a showroom or developer can range several undermount bathroom sinks together. Spec the model letter on every line. Adjust branding through the SANIKB OEM and ODM service.

Material and Finish: White Glazed Ceramic Undermount Basin

Each ceramic undermount basin is finished in a glossy white glaze and supplied in color White across the full range. The glazed ceramic surface gives a smooth, uniform appearance suited to both residential and commercial bathroom specifications. White-tone consistency from batch to batch matters when basins appear on a showroom wall or across repeated units in a development, and finish references are available on request to support reorders. Additional material details and finish specifications are set out on the spec sheet.

Undermount Installation and Drain Configuration

All four models are designed to mount beneath the countertop, with the rim set below the counter surface for a clean edge where the countertop meets the basin. Each size has its own cutout footprint, and the matching cutout dimensions and mounting templates are provided on request so fabricators can cut the opening accurately. The drawings show a 1.8 in (45 mm) drain opening with a 2.8 in (70 mm) reference dimension.

Overflow configuration is confirmed by model at the quotation stage. For installation planning, the drain must match the overflow condition: a basin supplied without an overflow is paired with a non-overflow free-flow drain, while a basin supplied with an overflow uses a standard pop-up drain rated for overflow basins. The correct drain pairing for each model is documented on the spec sheet before the order is placed.

OEM Ceramic Undermount Sink and Private Label Options

SANIKB manufactures this range factory-direct and supports OEM and ODM programs for distributors, importers, and private-label brands. Spec sheets and CAD cutout files are available on request for specification and listing work, and unbranded supply is available for private-label and own-brand programs. Branding, carton marking, and packaging are set per program. Send your requirements to scope a custom or private-label build.

Applications: Where This Rectangular Undermount Bathroom Sink Fits

This rectangular undermount bathroom sink is specified across multifamily and single-family residential bathrooms, hotel and hospitality guest rooms, and light commercial restrooms. The multi-size range helps match a single basin profile to different room types within one project, from compact secondary baths to primary vanities. Typical buyers include distributors and importers, multifamily and hospitality FF&E buyers, showroom dealers, general contractors, e-commerce resellers, and prefab or modular bathroom manufacturers.

Ordering and Export Packaging from a Wholesale Undermount Sink Supplier

As a wholesale undermount sink supplier, SANIKB sets MOQ, lead time, and pricing per program, with figures confirmed at the quotation stage. Export packaging and per-carton protection are scoped at the RFQ stage and sized to the destination market and order volume. Samples are available on request for evaluation ahead of a bulk order.

FAQs

Is this a true square undermount bathroom sink?

Our range classes it as square, and SN029A at 400 × 360 mm is close to it. Larger models are longer, up to 605 × 400 mm for SN029D, so they are rectangular in proportion. Check the length and width against your design before specifying a bowl-shape-critical vanity.

What sizes does the SN029 series come in?

Four models: SN029A at 400 × 360 × 175 mm (15 3/4 × 14 1/4 × 6 7/8 in), SN029B at 455 × 355 × 180 mm, SN029C at 495 × 385 × 170 mm and SN029D at 605 × 400 × 180 mm. All figures are overall exterior sizes. Request the spec sheet for bowl openings.

Does the basin come with an overflow?

Overflow configuration is confirmed by model at the quotation stage. The drain must match it: a basin without overflow takes a free-flow drain, and a basin with overflow takes a standard pop-up drain. Tell us the model letter and we confirm the correct pairing for these undermount bathroom sinks before the order is placed.

Can we buy SN029 unbranded for our own line?

Yes. We make the range ourselves and support OEM and ODM programs, including unbranded supply. Branding, carton marking and packaging are set per program. Send the model letters, quantities and artwork requirements, and we scope the program against the 20 pcs minimum.

What are the MOQ and lead time for the series?

Minimum order is 20 pcs, with mixed sizes allowed inside one 1×20 ft container. Lead time is set per program and confirmed in the quotation. Send sizes and quantities through an RFQ and we return terms for your project, plus sample options before bulk volume.
