Blanco 440214 – Frequently Asked Questions

1) Can the Blanco Diamond 60/40 double bowl sink be undermounted, or is it drop-in only?
Both. The Diamond 440DDU60 is a dual mount sink, so it can be dropped into the countertop with the rim sitting on the deck, or undermounted below a stone or solid surface top. That matters on a remodel where the existing top is laminate (drop-in is the only option) versus a new granite or quartz top where you want the undermount reveal. One sink covers either method, so you do not have to re-spec if the countertop plan changes mid-job.
2) Does a basket strainer come with the Blanco Diamond double bowl sink?
No. Basket strainers are sold separately on the Diamond 60/40, so budget two of them, one per bowl, plus the tailpieces and continuous waste to tie the two bowls into one trap. Plan that into the rough-in list rather than assuming the sink ships complete.
3) What colors does the Blanco Diamond SILGRANIT 60/40 sink come in?
Nine SILGRANIT colors: White (440216), Soft White (443063), Metallic Gray (440214), Volcano Gray (443100), Cinder (441465), Anthracite (440215), Coal Black (442908), Cafe (440213) and Truffle (441283). The color runs through the material rather than sitting on the surface as a coating, which is what keeps a chip or a scuff from showing a different color underneath. For a multi-unit property, order by the part number rather than the color name so every unit matches.
4) What accessories fit the Blanco Diamond 60/40 sink bowls?
Blanco lists four accessories made for this sink: a left bowl grid (220998), a right bowl grid (231342), a floating dish rack (236431) and a drain cover (517666). The grids are bowl-specific because the bowls are different sizes, so ordering two of the same part number leaves you with one that will not seat. Order the left and the right separately if you want both bowls protected.
5) Is a 60/40 split better than an equal double bowl sink?
A 60/40 gives you one large bowl and one smaller one instead of two mid-size bowls. The point is that a sheet pan, a stock pot or a roasting rack fits in the large side while the small side stays clear for rinsing or a strainer. An equal double bowl balances the two but caps the biggest item either side will take. If the kitchen mostly washes oversized cookware, the 60/40 is the split that handles it; if it runs two simultaneous tasks of the same scale, equal bowls suit better.
6) Is a SILGRANIT sink durable enough for a rental or commercial kitchen?
SILGRANIT is made from quartz sand, the hardest component of natural granite, and Blanco builds the Diamond to take heavy cookware and hot bakeware set down in the bowl. The surface is non-porous and smooth, so it does not absorb food and drink staining the way a porous stone composite would, and utensil scuff marks wipe off. For turnovers between tenants that means routine cleaning rather than refinishing, which is the practical difference against a coated or enameled bowl that chips through to a different color.
7) Which Blanco part number is the Coal Black Diamond 60/40 sink?
Coal Black is Blanco 442908 in the Diamond 440DDU60 double bowl dual mount line. Each color is its own manufacturer number, so quote and order by that six-digit number rather than by the model designation alone, otherwise the wrong color arrives against a spec that only said Diamond 60/40.
