Dark Emperador

Dark Emperador on a Boat-Shaped Body 140mm High

SP521 is the tallest body in this vessel group at a published 140mm, set on a 600 by 360mm plan in Dark Emperador marble.

01 / HEIGHT

140mm of published height

Taller than the trough bodies beside it. Ask for the internal bowl depth, which the published figure does not give.

02 / STONE

A named brown marble

Dark Emperador is a specific stone name with a published colour reference of #43342A. Order against the name, not against the description.

The long trough formats are shown together under stone vessel basins.

Fit & Clearance

600 by 360 Fits a Conventional Vanity Top

This is the most conventional footprint in the vessel group, which makes it the easiest to place in an existing range.

Size 23.6" x 14.2" (600 x 360 x 140 mm)
Mounting Above-counter (vessel)
Colour reference #43342A

A 600mm body sits comfortably on most standard vanity widths, so it can often be substituted into a range without redrawing the cabinet.

Because 140mm of basin sits above the counter, the finished rim height needs checking against the counter height on the drawing.

Confirm rim height above finished counter before selecting the tap.

Construction & Finish

Dark Emperador Is the Material Line, Not a Colour

Dark Emperador is a stone name, not a colour description. The specification treats it as the material line.

EMPERADOR

Dark brown marble, polished

The record gives Dark Emperador, polished, and #43342A. Nothing further is published about the surface.

Note that the title describes the bowl as oval while the type field lists it as boat-shaped. Get the profile drawing and use one description consistently across your own catalogue.

Fix a single shape description before the model is listed for sale.

Compliance

Written Confirmation in Place of a Mark

DOC
Confirmation before shipment

Written material confirmation and pre-shipment photographs are the practical substitute for a certification mark.

SP521 publishes no certification of any kind. That changes what a buyer should be asking for instead.

In place of a mark, ask for written confirmation of the stone name and photographs of the pieces allocated to your order. Both are normal requests on a stone purchase.

Procurement

A Standard Footprint Makes This the Stocking Body

The minimum here matches the rest of the stone group. The footprint is what makes this one different.

Published MOQ 50 pcs
Standard Lead Time 30-45 days (typical)

A conventional 600mm footprint tends to turn faster than the specialty lengths, which makes fifty pieces a reasonable stocking quantity rather than a commitment. Other stones on the same body are quoted through the SANIKB OEM and ODM program.

Include these details with the RFQ

  • Stocking quantity and reorder interval
  • Dark Emperador confirmed in writing
  • Profile drawing settling the shape description
  • Waste opening size and where it sits
  • Photographs of the allocated pieces
  • Carton build and pallet quantity
  • Documents required at your destination

Agree the reorder interval early so stone can be reserved against it.

FAQs

What stone and shape define this Emperador basin?

It is an oval Dark Emperador marble vessel, a rich brown stone with light veining, carved into an elongated boat-shaped bowl.

Is this a wide basin for a double or feature vanity?

Yes, at 23.6" x 14.2" (600 x 360 x 140 mm) the long boat form is generous enough to anchor a feature vanity or double-bowl layout.

How is this brown stone vessel sink maintained?

As a natural marble it should be sealed and cleaned with pH-neutral products; acidic cleaners must be avoided to protect the polished brown surface.
