Blanco Anthracite Color Coordinated Metal Waste Flange

A decorative metal waste/disposal flange in Anthracite finish that coordinates with Blanco SILGRANIT® kitchen sinks. It finishes the sink drain opening neatly and provides a functional connection to a garbage disposal, helping prevent food debris from entering your plumbing and giving a polished look to the sink area.

Coal Black
A rich, deep dark pitch-black finish with a bold, dramatic presence. Coal Black delivers a sleek, modern look that anchors the kitchen with confidence and pairs beautifully with contemporary cabinetry and metallic accents.

Anthracite
A deep charcoal-black tone with subtle granite flecking that adds depth and texture. Anthracite offers the sophistication of black with a softer, more dimensional stone appearance.

Cinder
A dark slate gray inspired by natural stone. Cinder strikes the perfect balance between black and gray, offering a refined, grounded neutral that complements both modern and transitional spaces.

White
A crisp, clean white with a timeless appeal. Bright and versatile, this classic finish enhances light and contrast, making it an effortless choice for both kitchens and laundry rooms.

Truffle
A soft, earthy taupe blending warm brown and gentle gray tones. Truffle brings subtle warmth and organic elegance, creating a refined neutral that pairs beautifully with natural materials and layered finishes.

Café Brown
A warm, medium brown reminiscent of milk chocolate. Café Brown adds richness and comfort to the space, offering a welcoming, grounded look with understated sophistication.

Soft White
A creamy, warm white designed to complement quartz and stone surfaces. Soft White delivers a gentle, inviting tone that feels refined and cohesive rather than stark. Blanco’s newest color has been an immediate success, answering the industry’s demand for a perfectly balanced, in-between tone.

Volcano Gray
A rich mid-tone medium gray with warm undertones and a smooth, stone-inspired finish. Deeper than light gray but lighter than charcoal, Volcano Gray offers a substantial, modern look and pairs exceptionally well with stainless steel and dark metal appliances.
