Blanco 442077 – Frequently Asked Questions

1) How low is the divider on the Blanco Diamond 50/50 low divide sink, and will a baking sheet fit across it?
The divider on the Diamond double bowl undermount sits 5-1/2 inches up from the sink bottom, so large pots and baking sheets can lay across the low wall instead of being trapped in one bowl. You still get two equal 50/50 bowls for separating cleaning from prepping, but the low wall means the sink behaves closer to a single bowl when you need the length.
2) Is the Blanco Diamond DIA440DD50 an undermount sink, and what does that mean for the countertop?
Undermount only. The Diamond 50/50 low divide mounts beneath the counter so there is no rim sitting on the deck for grime to collect around, which means it needs a solid surface countertop cut and finished for an undermount, plus faucet holes drilled in the deck rather than the sink. Mounting clips are not included with the sink.
3) Does the Blanco Diamond SILGRANIT sink come with a basket strainer or drain assembly?
No. The basket strainer and the installation clips both ship separately from the Diamond 50/50 undermount sink, so a plumber ordering for a full install needs to add a strainer, clips, and the tailpiece and trap for the two bowls. Plan the order that way or the sink will land on site incomplete.
4) What is SILGRANIT and how does it hold up to heavy cookware in a rental or busy kitchen?
SILGRANIT is Blanco's composite made from quartz sand, the hardest component of natural granite. The Diamond bowls are built to take heavy cookware and hot bakeware, and the surface is non-porous and smooth, so scuff marks from utensils and stains from food and drink wipe off rather than soaking in. For a property manager turning units or a hospitality kitchen, that non-porous surface is the practical difference against a stainless bowl that dents and shows every scratch.
5) What colors does the Blanco Diamond 50/50 low divide sink come in?
Nine SILGRANIT colors: White, Soft White, Cinder, Truffle, Anthracite, Metallic Gray, Volcano Gray, Cafe, and Coal Black. If you are standardizing several units or matching an existing Blanco sink already in the building, order by the part number rather than the color name, because White (442074) and Soft White (443069) are two different shades.
6) Which Blanco part number do I order for a Coal Black or Anthracite Diamond double bowl sink?
Each color of the Diamond 50/50 low divide undermount carries its own Blanco item number: Coal Black is 442914, Anthracite is 442075, Cinder 442071, Truffle 442072, White 442074, Metallic Gray 442077, Cafe 442078, Soft White 443069, and Volcano Gray 443106. Distributors and spec writers should quote the color-specific number, since the DIA440DD50 designation covers the whole color range.
7) What accessories are made to fit the Blanco Diamond double bowl low divide sink?
Four accessories are matched to this sink and ordered separately: a left bowl grid (221008), a right bowl grid (221009), a floating dish rack (236432), and a drain cover (517666). The grids are sided, so a 50/50 double bowl takes both the left and the right part number if you want protection in each bowl.
8) Should I choose a 50/50 low divide sink or a standard full-height double bowl?
A full-height divide keeps the two bowls genuinely separate, which suits anyone who wants to soak on one side with no spillover. The low divide version splits the sink into a cleaning bowl and a prep bowl for rinsing, washing, soaking, spraying and straining, but drops the wall to 5-1/2 inches off the bottom so oversized pans and sheet pans can sit across both bowls. Pick the low divide if the complaint about your current sink is that nothing big fits; pick a full divide if you need true separation.
