If you're outfitting a galley kitchen, prep station, or wet bar, the Blanco Precis 24" Compact Undermount Kitchen Sink in Anthracite (model 440151) is one of the most popular small-footprint single-bowl sinks on the market. Made from Blanco's proprietary Silgranit composite, it promises stain, scratch, and heat resistance in a sleek, dark finish that hides water spots better than stainless. After examining the build, dimensions, and real-world usability, here's how this compact sink stacks up.
TL;DR: The Blanco Precis 24" (440151) is a thoughtfully engineered Silgranit undermount sink ideal for small kitchens and prep stations. Its anthracite finish is durable and forgiving, the deep single bowl punches above its size class, and installation is straightforward — but you'll need a 27" minimum base cabinet and patience with the gentle slope toward the rear-set drain.
Overview
The Precis line is Blanco's modern-leaning Silgranit collection, characterized by tight radius corners, a flat bottom, and a low-divide or single-bowl layout. The 24" compact model (440151) is the smallest single-bowl option in the family, designed for kitchens where space is at a premium without giving up usable bowl depth. Anthracite — a near-black charcoal — is the most popular Silgranit color and pairs well with stainless, brass, or matte black faucets. If you're planning a broader kitchen refresh, our KitchenAid KDTM354ESS dishwasher review covers a popular pairing in the same price tier.

Design and Build Quality
Silgranit is the headline feature here. Unlike enameled cast iron or thinner composites, Silgranit feels solid and dense — the 24" Precis weighs roughly 22 pounds, which is substantial for its size. The surface has a fine matte texture that resists fingerprints, hard water spots, and minor scratches from cookware. The anthracite color isn't a coating; it's pigmented through the material, so chips (which are rare) won't reveal a contrasting substrate.
The bowl interior uses tight radius corners — not zero radius, but tighter than older Blanco models — giving it a contemporary look while still being easy to wipe clean. The bottom slopes gently toward the rear-offset drain, which keeps standing water minimal and frees up under-sink plumbing space.
Why anthracite? Among Silgranit's color palette, anthracite is consistently the most forgiving for everyday use. Lighter shades like white or biscuit can show coffee or wine residue if not wiped promptly, while anthracite blends with most countertop colors from white quartz to butcher block.
Performance in Daily Use
Capacity
At 8" deep, the Precis 24" holds a surprising amount. A standard 13" dinner plate fits flat on the bottom, and you can stack a few cookie sheets or a Dutch oven without splash issues. It's not going to swallow a half-sheet pan like a 30" sink will, but for a compact bowl, the depth is its saving grace.
Noise and Vibration
Silgranit's density makes this sink remarkably quiet. There's no need for added sound-dampening pads — running water, garbage disposals, and dropped utensils all register noticeably softer than on stainless steel.
Cleaning
Day-to-day cleaning is as simple as a wipe with soapy water. For mineral buildup or food stains that do appear, a paste of baking soda and water works well. Avoid abrasive scrubbers and prolonged use of bleach-based cleaners — occasional diluted bleach for disinfection is fine, but regular use can gradually dull the matte finish.
Pros and Cons
Pros
- Genuine Silgranit material — durable and color-fast
- Quiet operation without added pads
- 8" depth is generous for a compact sink
- Anthracite hides water spots and minor wear
- Heat resistant to 536°F
- Limited lifetime warranty
Cons
- Requires a 27" minimum base cabinet despite the 24" sink width
- Heavier than stainless — undermount support is critical
- Premium pricing vs. comparable stainless options
- Rear-offset drain placement isn't ideal for every plumbing layout
- Single bowl only — no half-bowl option in this size
Installation Considerations
Because the sink is heavy and undermount, proper support is non-negotiable. Most installers use a combination of silicone adhesive, mechanical clips, and a plywood cradle or steel brackets fastened to the cabinet sides. If you're installing under stone (quartz, granite, or quartzite), the fabricator should template directly from the sink rather than relying solely on Blanco's spec sheet to ensure a perfect reveal.
Cabinet sizing note: The 24" model number is the sink's external length, but the required base cabinet is 27" minimum. The extra 3" accounts for the cabinet's interior framing, side panels, and the mounting clearance Silgranit needs for proper undermount support. Builders frequently get this wrong on remodel jobs — confirm your cabinet width before ordering.
The 3.5" drain opening fits standard garbage disposals and basket strainers. Blanco sells matching anthracite-colored accessories (sink grids, cutting boards, and drain covers) sized specifically for this model, which can extend the sink's usability.
Who Should Buy It?
The Precis 24" is a strong fit for:
- Galley kitchens, condos, or apartments where every inch counts
- Secondary prep sinks in islands or butler's pantries
- Wet bars and coffee stations
- Laundry rooms or mudrooms wanting a more refined look than utility sinks
- Homeowners who want a darker, low-maintenance alternative to stainless
Need a larger single-bowl in stainless? The Kohler Vault 35-1/2" undermount single bowl and Ruvati Gravena 33" 16-gauge undermount are worth considering.
If you regularly wash large roasting pans, sheet trays, or stockpots, step up to the 27" or 30" Precis instead — the extra width matters more than depth for those tasks. For a larger Blanco option with a low-divide layout, see the Blanco Empressa 1-3/4 Low Divide Undermount Sink.
How It Compares
If you're cross-shopping materials, the most popular stainless alternatives in this category include the Kraus Standart PRO 33" 16-gauge undermount and the Elkay Crosstown double-bowl undermount, while the Ruvati Fireclay 30" farmhouse sink is a strong fireclay option.

| Scratch resistance | Excellent | Fair (shows scratches) | Good (can chip) |
| Color options | 9 colors incl. anthracite | Brushed or polished (no color options) | Typically white |
| Weight | ~22 lbs | ~12–15 lbs | ~40+ lbs |
Frequently Asked Questions
Does the Precis 24" work with a garbage disposal?
Yes. The 3.5" drain opening accepts standard disposals from InSinkErator, Waste King, and other major brands. Use a flexible coupling and ensure the disposal is well-supported so its weight doesn't hang on the sink alone.
Can I set hot pans directly in the sink?
Silgranit is rated to 536°F, so a hot pot from the stove won't damage the surface. That said, repeated thermal shock — like running cold water on a 500°F pan in the sink — should be avoided.
Will anthracite fade over time?
The color is integral to the Silgranit material, not a surface coating, so it won't fade with normal use. UV exposure isn't typically a concern indoors, and the matte finish stays consistent for years with routine cleaning.
Is a sink grid necessary?
It's optional but highly recommended. A bottom grid keeps cookware off the sink floor, protects the finish from heavy items, and improves drainage. Blanco sells a model-specific stainless grid for the Precis 24".
What's the difference between Precis and Diamond lines?
Both are Silgranit. Precis features tighter radius corners and a more contemporary look, while Diamond has slightly softer curves and broader bowl shapes. The Precis 24" compact has no direct equivalent in the Diamond line.
Final Verdict
A premium small-footprint sink that earns its price
The Blanco Precis 24" Compact Undermount in Anthracite (440151) is one of the best compact sinks on the market for buyers who value material quality, quiet operation, and a refined modern aesthetic. The Silgranit construction is genuinely better than budget composites, the anthracite finish is forgiving, and the 8" bowl depth makes the small footprint feel larger in use. The main caveats — required 27" cabinet, premium pricing, and weight — are easy to plan around. For compact kitchens, prep stations, and bars where you want something better than stainless, this sink is hard to beat. At roughly twice the price of a comparable stainless undermount, it's a deliberate upgrade — one that makes sense if you're keeping the kitchen long-term or simply want a material that stays looking new with minimal effort.
