Blanco 440178 – Frequently Asked Questions

1) Does the Blanco Diamond DIA440DU60 sink come with a strainer and mounting clips?
No. The basket strainer and the installation clips are both sold separately on the Diamond 60/40 undermount, so budget for them on the same order or the sink cannot be hung or drained. Grids and a drain cover are separate as well: left grid 220998, right grid 231342, floating dish rack 236431, drain cover 517666.
2) Can the Blanco Diamond DIA440DU60 be installed as a drop-in on a laminate counter?
No. The Diamond DIA440DU60 is an undermount sink, so it hangs beneath the countertop and needs a solid-surface top, stone or quartz typically, with a finished cutout edge. Laminate has an exposed particleboard core at the cutout and is not a substrate for undermount work. If the counter is laminate, you want a drop-in sink with a rim instead.
3) What colors does the Blanco Diamond 60/40 undermount sink come in?
The Diamond SILGRANIT 60/40 double bowl undermount sink is offered in nine SILGRANIT colors: White, Soft White, Cafe, Truffle, Metallic Gray, Volcano Gray, Anthracite, Cinder, and Coal Black. The color runs through the material rather than sitting on the surface, so scuffs and chips do not expose a different substrate underneath. Order by the color-specific number, for example 440180 for White, 440179 for Anthracite, and 442909 for Coal Black.
4) Which grid fits the Blanco Diamond 60/40 double bowl sink, left or right?
Both, and they are different parts because the bowls are different sizes. The large bowl and the small bowl each take their own grid: 220998 for the left, 231342 for the right. If you want the bottom of both bowls protected, you order two grids, not one.
5) Is SILGRANIT tough enough for a rental unit or a busy commercial kitchen?
SILGRANIT is built from quartz sand, the hardest component of natural granite, and the Diamond bowls are made to take heavy cookware and hot bakeware set straight down. The surface is non-porous and smooth, so it does not absorb food or drink staining, and utensil scuff marks wipe off rather than needing an abrasive. For a property manager standardizing across units, that means no coating to wear through and no rim seam collecting grime, since the sink mounts under the counter.
6) Should I get a 60/40 double bowl or a single bowl kitchen sink?
Go 60/40 when the household still washes and rinses as separate operations, or wants to soak something in one side while the other stays clear. The split gives you a large bowl big enough for oversized pans while keeping the small bowl free for rinsing, spraying, or straining. A single bowl is the better call when the priority is laying a full sheet pan or a roasting rack flat, since neither bowl of a 60/40 is as wide as the whole cabinet run.
7) Does the Blanco Diamond undermount sink have faucet holes drilled in it?
No holes are drilled in the sink itself. Undermount sinks sit below the counter, so the faucet, soap dispenser and air switch are all drilled into the countertop by your fabricator. Decide the deck layout before the stone goes to the shop, because adding a hole after templating means going back to the fabricator.
