Design

A plain round fossil limestone bowl in near black

SP178 is a round above-counter basin in fossil limestone, 16.5 in across and 5.5 in tall. The wall is left plain so the stone does the work.

01 / SURFACE

Fossil scatter on a dark body

Cream fossil rings sit across a near-black ground referenced at #25221F. The pattern is different on every piece.

02 / PROFILE

Unbroken wall, no shaping

There is no fluting, step or foot. A clean cylinder keeps attention on the fossil marks and suits plain joinery.

It is the quiet option in our stone vessel basin range when a room already carries pattern elsewhere.

Fit & Clearance

420 mm across with 140 mm above the counter

A plain cylinder gives a simple footprint. Rim diameter and base diameter are effectively the same.

Overall size Ø16.5" × 5.5" H (Ø420 × 140 mm)
Mounting Above-counter (vessel)
Material Fossil limestone

Allow the full 420 mm of flat counter plus a working margin front and back. Nothing narrows toward the base.

Dark stone shows water marks more readily than pale. A spout aimed at the drain keeps splash inside the bowl.

Drain position is confirmed on the drawing issued with the quotation.

Construction & Finish

Fossil limestone with the finish confirmed at sample

SP178 is specified in fossil limestone. The finish recorded on the specification is polished.

Limestone

One block, worked and finished

The bowl is cut from solid limestone. Surface treatment is applied after shaping, not before.

The model name carries a honed descriptor while the specification lists polished. Confirm in writing which face your order is built to, since the two read very differently in dark stone.

A honed and a polished piece can be quoted side by side if you want to compare.

Compliance

Get the finish and the paperwork in writing

DOC
Order file over verbal agreement

Finish, stone type and documentation scope are recorded on the order confirmation.

No certification appears against SP178. This page claims none. Where the order is going decides the paperwork, so raise it at RFQ stage.

Written confirmation of finish and stone type belongs in the order file. It settles a later appearance dispute with a retail customer.

Procurement

Buying SP178 for stock or for a project

Published terms for the plain fossil bowl.

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

Finish is the variable worth locking down for a house range. Alternative faces and own-brand packaging are handled on the SANIKB OEM and ODM program.

Stocking distributors take it alongside a pale bowl so the display covers both ends of the palette.

Include these details with the RFQ

  • Model SP178 and quantity
  • Finish required, honed or polished
  • Destination port and Incoterm
  • Acceptable density of fossil marking
  • Own-brand carton artwork
  • Sample approval before production

Lead time is indicative and confirmed on the quotation.

FAQs

What does the honed finish mean for the SP178 fossil limestone basin?

The honed surface is matte and non-reflective rather than polished, giving the black fossil limestone a soft, contemporary look that hides water spotting in busy bathrooms.

Are visible fossils part of this stone's natural pattern?

Yes, the fossil limestone carries embedded shell and fossil markings, so each round vessel shows unique natural inclusions across the surface.

What size is this round vessel for spec sheets?

It measures Ø16.5" × 5.5" high (Ø420 × 140 mm), a standard above-counter round that drops onto most vanity tops without modification.
