The Blanco Precis 24" Compact Undermount Kitchen Sink in Anthracite (model 440151) is engineered for small kitchens, islands, and prep stations where space is at a premium but design standards remain high. Made from Blanco's proprietary Silgranit composite, this single-bowl undermount sink delivers a clean, contemporary look while standing up to the rigors of daily cooking. This review covers what makes the Precis 440151 distinctive, how it installs, how it compares to other compact undermount sinks, and how to keep it looking new for years.
TL;DR: The Blanco 440151 is a compact 24-inch undermount sink in Anthracite Silgranit—durable, scratch- and stain-resistant, and ideal for small kitchens, islands, or prep stations. Its single-bowl design maximizes usable basin space, and the matte stone-like finish hides water spots better than stainless steel.
Overview of the Blanco Precis 440151
The Precis collection is Blanco's modern, geometric line, characterized by tight radius corners and clean lines. The 24-inch compact model is the smallest single-bowl size in the family, making it a strong fit for small kitchens, secondary prep zones, bar areas, and tight-galley layouts where a full 30- or 33-inch sink isn't practical.

What Is Silgranit?
Silgranit is Blanco's signature material, composed of approximately 80% natural granite blended with high-performance acrylic resins. The result is a non-porous surface that resists scratches, chips, stains, heat (up to 536°F), and impact far better than enamel-coated cast iron or thin-gauge stainless. The matte finish is consistent throughout the material, so minor surface wear doesn't reveal a different color underneath.
Why Anthracite? Anthracite is one of Blanco's most popular Silgranit colors—a deep, neutral charcoal that pairs well with both warm wood cabinetry and cool modern palettes. It hides water spotting and food residue between cleanings noticeably better than lighter tones.
Design and Build Highlights
- Tight-radius corners maximize the usable basin area within the 24-inch footprint.
- Sloped basin floor directs water to the drain, reducing standing water.
- Pre-drilled rear drain placement leaves more clear space below the sink for storage and disposal plumbing.
- Sound-dampening is inherent to the dense Silgranit material—no added pads required.
- Hygienic surface resists bacteria growth thanks to the non-porous composition.
Pros and Cons
Pros
- Compact 24" size fits small cabinets and islands
- Silgranit is highly durable and stain-resistant
- Anthracite hides water spots and minor smudges
- Heat-resistant up to 536°F
- Modern, low-profile undermount aesthetic
- Naturally quiet—no extra dampening needed
Cons
- Single bowl only—no separate prep basin
- Heavier than stainless; requires solid mounting support
- Hard objects dropped at speed can chip dishware (sink itself stays intact)
- Requires granite, quartz, or solid-surface countertop—not compatible with laminate
Installation Considerations
Because the 440151 is an undermount sink, it must be installed beneath a countertop with a cutout that matches Blanco's template. Plan for the following:
- Countertop type: Granite, quartz, solid surface, or other waterproof materials. Laminate is not suitable for undermount installation.
- Cabinet base: A 27-inch base cabinet is the minimum recommended width to accommodate the sink and mounting hardware comfortably.
- Support: Silgranit sinks are heavy. Use proper undermount clips, brackets, or a plywood support cradle attached to the cabinet sides.
- Faucet drilling: Faucet holes are drilled into the countertop, not the sink itself, giving you flexibility in faucet placement.
- Sealing: Use a quality 100% silicone sealant between the sink rim and the underside of the countertop.
Pro tip: Have the sink on hand before your countertop fabricator templates the cutout. Even small variations in sink dimensions matter, and fabricators prefer to measure the exact unit being installed.
Best Use Cases
Small Primary Kitchens
In apartments, condos, or compact homes where the run of countertop is limited, a 24-inch sink keeps prep space available on either side. If you're outfitting a full small-kitchen remodel, pair the sink with a quiet, space-efficient dishwasher—our Bosch 300 Series SHPM88Z75N buying guide covers a strong option in the same design tier.
Kitchen Islands
The Precis 440151 makes an excellent island prep sink—small enough not to dominate the island, deep enough to wash a sheet pan or fill a stockpot.
Bar and Beverage Stations
The clean lines and dark Anthracite finish look upscale in entertaining areas and wet bars. For a fully equipped entertaining zone, consider pairing it with a premium compact dishwasher like the one covered in our KitchenAid KDTM354ESS guide.
Secondary or Auxiliary Sinks
Use it as a dedicated coffee station, butler's pantry, or laundry-room utility sink.
Care and Maintenance
Silgranit is low-maintenance, but a few habits will keep it looking pristine:
- Daily: Rinse and wipe with a soft cloth or sponge after use.
- Weekly: Clean with mild dish soap and warm water, or a non-abrasive cleaner formulated for composite sinks.
- Hard water spots: A diluted vinegar solution or a Silgranit-specific cleaner removes mineral buildup.
- Restoring sheen: Periodically apply a small amount of mineral oil or a Silgranit conditioner to revive the matte finish, especially in hard-water areas.
- Avoid: Steel wool, harsh abrasives, and bleach-heavy cleaners used continuously.
Compatible Accessories
Blanco offers accessories tailored to the Precis line that can transform the sink into a workstation:
- Custom-fit cutting boards sized to span the sink rim
- Stainless steel bottom grids to protect the basin and elevate dishes for drainage
- Coordinating colander and drainer baskets
- Matching Silgranit-finished faucets in Anthracite for a fully unified look
How It Compares to Other Compact Sinks
Compared with stainless undermount sinks in the same size class—such as the Kraus Standart PRO 33-inch single bowl or the Ruvati Gravena 33-inch 16-gauge—the Blanco 440151 offers a quieter, warmer aesthetic and avoids the visible scratching and water spotting that plague brushed stainless. Versus enamel-coated cast iron (which can exceed 100 lbs for a comparable bowl), Silgranit weighs significantly less, won't chip down to a contrasting substrate, and offers a wider range of modern colors. Against fireclay options like the Ruvati Fireclay 30-inch farmhouse sink, Silgranit is more impact-tolerant, noticeably lighter (fireclay sinks in this size class often weigh 40–60 lbs), and easier to install due to precise, machined dimensions.
Considering a Larger Sink Instead?
If you decide 24 inches is too small for your primary kitchen, two strong upgrades from the same undermount category are worth a look. The Kohler Vault 35-1/2" single bowl (K-3942-1-NA) offers a much larger basin with a similar clean undermount profile, while the Blanco Empressa 1-3/4 low-divide undermount keeps you in the Blanco family if you'd prefer a split-bowl configuration for prep and rinsing.
Frequently Asked Questions
Will the Anthracite color fade over time?
No. Silgranit color runs through the entire material and is UV-stable, so it won't fade or change shade with normal use and cleaning.
Can I place hot pans directly in the sink?
Silgranit handles brief contact with hot cookware well. For best long-term results, run cool water when transferring very hot items.
What's the minimum cabinet size needed?
A 27-inch base cabinet is recommended to allow room for the sink body, mounting hardware, and plumbing connections.
Is a garbage disposal compatible?
Yes. The 440151 is designed for standard drain configurations, and most major garbage disposals are compatible—confirm the exact drain opening spec with Blanco or your plumber before purchasing a disposal unit.
How do I remove a stubborn stain?
For tough stains, make a paste of baking soda and water, apply it to the area, let it sit for 10–15 minutes, then scrub gently with a non-abrasive sponge and rinse.
Does it come with mounting hardware?
The 440151 typically ships with a mounting kit that includes undermount clips. Your countertop fabricator may supplement or replace these with hardware suited to your specific countertop material, so confirm the approach with them before installation.
Final Thoughts
The Blanco Precis 24" Compact Undermount Sink in Anthracite (440151) is a thoughtful choice when you need a smaller sink that doesn't compromise on durability or aesthetics. The combination of Silgranit's resilience, the timeless Anthracite color, and the clean modern geometry of the Precis line makes it equally at home as a primary sink in a small kitchen or as a stylish secondary basin in a larger one. With minimal maintenance, it should remain a striking, functional centerpiece for many years.
