    GL48 Diamond Rectangle

    Diamond-cut facets scaled onto a 505 mm rectangle

    GL48 carries the faceted treatment on the larger of the two rectangular bodies in this group. The plan size is 505 by 370 mm.

    01 / SCALE

    Facets read larger on a big body

    The same cut pattern covers more surface here than on a compact round. It becomes the feature of the room rather than a detail on the counter.

    02 / CODES

    A plain GL48 line exists

    GL48, GL48-A, GL48-IR, GL48-J and GL48-L1 are published. The unsuffixed code is a real line, so an order that omits the suffix is ambiguous rather than invalid.

    Facet pattern and body size are separate choices on a shortlist. Both are visible across the glass vessel basin collection.

    Fit & Clearance

    Counter depth needed behind a 370 mm body

    Depth behind the bowl is the constraint here. The body runs 370 mm front to back on a 505 mm length.

    Overall size
    19 7/8" × 14 5/8" × 5 1/8" (505 × 370 × 130 mm)
    Mounting
    Above-counter (vessel)
    Shape
    Rectangular, diamond-cut facets

    370 mm of depth leaves little behind the bowl on a standard 450 mm top. Either the top gets deeper or the tap moves to the wall, and that decision belongs in the drawing set.

    A rectangular body wants its edges square to the counter. Set out the position from two datum lines rather than centring by eye on site.

    Issue the setting out dimensions with the counter order.

    Construction & Finish

    Weight and thickness on the larger rectangle

    The body is larger than its rectangular sibling. The material line is the same short entry.

    Color · 5

    Two figures to request early

    The material line reads tempered art glass and stops. Unit weight and wall thickness are not stated for a body this size.

    • Clear Crystal Clear Crystal
    • Black Black
    • Iridescent Iridescent
    • Gold Gold
    • Blue Blue

    On a body this size both numbers affect handling on site and the cost of getting it there. Ask for weight, packed cube and thickness with the quotation and hold them on your product record.

    Pass the unit weight to whoever handles the goods at delivery.

    Compliance

    Transit and handling paperwork on a large glass item

    Packing standard agreed in advance

    Write the packing method and the claim procedure into the order. Both are easier to settle before goods travel.

    GL48 is cUPC listed. The published specification also holds material, type, mount, finish, size and MOQ. Before it goes into a submittal, request the current listing number and certificate validity so the documentation matches your destination market.

    Large glass items usually raise packing and handling questions rather than compliance ones. Agree the packing standard and the damage reporting route in writing before the first shipment leaves.

    Procurement

    Consolidating GL48 into a mixed container

    The record lists 100 pieces as the minimum.

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

    A hundred pieces of a 505 by 370 body takes real cube, so buyers usually place this model as part of a mixed glass booking rather than on its own container.

    List every model going into the same shipment at enquiry. Carton design and own-brand printing across a mixed load are handled through the SANIKB OEM and ODM program.

    Include these details with the RFQ

    • Quantity per GL48 code including the plain line
    • Other models in the same container
    • Unit weight, thickness and packed cube
    • Packing standard and damage reporting route
    • Destination port and Incoterm
    • Requested loading window

    Send the full model list before pricing so the load can be planned once.

    FAQs

    What is GL48 and what is it made of?

    GL48 is a rectangular diamond-cut glass vessel sink, an above-counter bathroom basin cut from toughened (tempered) safety glass. It measures 505x370x130mm and sits on a standard vanity top, pairing with a vessel or wall-mounted faucet. The non-porous glass surface wipes clean and resists staining for everyday use.

    What size is GL48 and where does it fit?

    GL48 measures 505x370x130mm (W x D x H). As an above-counter vessel basin it suits powder rooms, hotel and hospitality vanities, and residential bathrooms where a decorative glass bowl is the centerpiece. Confirm faucet hole and drain placement on the spec drawing before installation.

    What colors and finishes does GL48 come in?

    GL48 is offered in 5 colors — Clear Crystal, Black, Iridescent, Gold, Blue. As a glass vessel sink OEM/ODM manufacturer we can also tailor color, texture and size to your program; share your target finish and market and we will match it.

    Is GL48 tempered safety glass and how durable is it?

    Yes. GL48 is built from tempered (toughened) glass for impact and thermal resistance, finished with smooth edges and a non-porous surface that cleans with a soft cloth and mild cleaner. Avoid abrasive pads to keep the gloss.

    What are the MOQ, OEM/ODM and private-label terms for GL48?

    MOQ for GL48 is confirmed in the current factory-direct quotation from SANIKB. OEM/ODM and private-label programs cover custom color, size, logo and export packaging engineered for ocean freight. We welcome pre-shipment inspection so your team verifies quality before goods leave the plant.

    What is the lead time and how do I request a wholesale quote for GL48?

    Lead time depends on order size, color and customization, and is confirmed with each quote rather than a generic figure. Share quantities, colors and destination for a costed quote. To see the full range, browse our glass vessel sinks collection.
