Blanco 440219 – Frequently Asked Questions

1) Can the Blanco Diamond 50/50 double bowl sink be undermounted, or is it drop-in only?
Both. The Diamond 50/50 is a dual mount sink, so it can be dropped into the countertop or undermounted below it. One thing to plan around: the optional cutting board (item #440229) fits the drop-in installation only. The left and right grids (items #221008 and #221009) work either way.
2) How many faucet holes does the Blanco Diamond 50/50 sink come with?
It arrives pre-drilled for a single hole faucet, with four additional knock-out holes you can open on site for accessories like a soap dispenser, air switch, air gap or filtered water tap. Punch only what the job needs, since the knock-outs stay sealed until you open them.
3) Does the Blanco Diamond 50/50 kitchen sink include a strainer or drain assembly?
No. Basket strainers are sold separately on the Diamond 50/50, so budget a strainer per bowl (two for this sink) on the same order. The bottom grids are separate too, split left and right (items #221008 and #221009).
4) What is SILGRANIT and how does it hold up to heavy pots and hot pans?
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 instead of soaking in. For a rental turn or a busy commercial kitchenette, that non-porous surface is the reason it stays looking right without a maintenance routine.
5) Should I get a 50/50 double bowl or a single bowl kitchen sink?
Go 50/50 if the dishes get done by hand. Two equal bowls let you stack dirty dishes and utensils in one while you prep, rinse or soak in the other, and each bowl handles rinsing, washing, soaking, spraying and straining. A single bowl is the better call when the household or unit runs a dishwasher and needs room for a full sheet pan or a roasting rack, since a 50/50 splits that space in half.
6) What colors does the Blanco Diamond 50/50 SILGRANIT sink come in?
Nine SILGRANIT colors: White (440221), Soft White (443067), Cafe (440218), Truffle (441285), Metallic Gray (440219), Volcano Gray (443104), Cinder (441466), Anthracite (440220) and Coal Black (442912). If you are standardizing across a building, order by that item number rather than the color name, since White and Soft White are two distinct products and so are Metallic Gray and Volcano Gray.
7) Which bottom grid do I order for the Blanco Diamond 50/50 double bowl sink?
Two different grids, one per bowl: item #221008 for the left bowl and item #221009 for the right. They are not interchangeable, so order both if you want the base of each bowl protected from pots and cast iron.
8) Is the color on a SILGRANIT sink a coating that can wear off?
No. SILGRANIT is a solid composite of quartz sand, so the color runs through the material rather than sitting on it as a surface finish. That is why utensil scuffs come off instead of exposing a different color underneath, and it is the practical difference from an enameled cast iron sink, where a chip shows the substrate.
