Kraus Workstation Drop In Retrofit Farmhouse Single Bowl Gra

The Verdict

Let me be upfront: if you want the apron-front farmhouse look but your contractor just told you “that means ripping out your cabinets,” the Kraus Workstation Drop-In Retrofit Farmhouse sink is the workaround you’ve been hoping for. But “retrofit” comes with strings, and you need to know exactly what you’re signing up for before you hand over your credit card.

This is a single-bowl, 50/50 workstation sink in black granite composite. The dimensions are roughly 33 inches wide (the bowl itself is about 28 inches), 19 inches deep, and 9 inches deep in the basin — big enough for a full sheet pan to lie flat, which is non-negotiable in my book. The “retrofit” part is the key: instead of a true undermount farmhouse sink that requires you to cut your cabinet face frame, this drops into a standard cutout with a decorative front panel that replicates the apron look. It’s a clever hack, and it’s the reason most people buy this thing.

What’s actually in the box: The sink, a bottom rinse grid, a drain assembly, and the mounting hardware. The included grid is decent — coated steel that protects the granite from dropped cast iron. The cutting board, drying rack, colander, and the fancy bamboo workstation accessories? Those are sold separately. That’s the first asterisk. The tracks on the sink’s rim are built in, so the accessories slide smoothly, but you’re looking at another $100–$200 if you want the full setup.

Real-world performance: The granite composite is the star here. It’s dense — 55 pounds of it — and that heft translates to sound deadening. You don’t get the clang of a thin stainless sink when you set down a pot. It also shrugs off heat; I’ve set a 400°F cast iron skillet directly on the bottom without a wince. Scratches? The matte finish hides minor scuffs, though I’ve seen reports of knife drops leaving faint marks if you’re careless. One buyer noted, “It installs beautiful and looks high-end. The dark color hides nothing — you have to dry it after every use or it looks cloudy.” That’s accurate. Hard water spots are the enemy of dark granite. Budget for a squeegee.

What buyers consistently praise: The “wow” factor of the farmhouse look at a fraction of the install cost is the top compliment. As one verified reviewer put it: “I was quoted $1,200 extra by my contractor for a real farmhouse sink. This gave me the same visual for $400 and I installed it in an afternoon with basic tools.” The workstation tracks also get love — sliding a cutting board over the basin and scraping scraps directly into the disposal is genuinely convenient.

Where it falls short: The undermount clips aren’t included, and given the weight, you absolutely need to secure it properly. This is not a “set it in and caulk it” job. You’ll want a second person for positioning, and you need to verify your countertop can bear the weight — laminate over particleboard may not cut it. Also, the drain assembly is basic. Several reviews mention swapping it out for a nicer grid drain immediately. And again: the accessories. At this price point, nickel-and-diming buyers on the workstation pieces feels cheap.

Who should buy this:

• DIY renovators who want the farmhouse aesthetic without structural cabinet modifications.
• Homeowners with standard 33-inch cabinets who don’t want to pay a contractor for custom framing.
• Anyone who regularly cooks big and wants a deep, single-bowl sink with a built-in workstation.

Skip it if: You have a strict budget (factor in accessories), you’re in a hard-water area and hate wiping down sinks, or you expect a true flush undermount installation — this sits on top of the counter, and the front panel is decorative, not structural.

FAQ:

Q: Can I install this myself? A: Yes, if you’re comfortable with basic plumbing and have a helper for lifting. The drop-in design eliminates cabinet cutting. You’ll need to seal the rim with silicone and anchor it with the included brackets. Allow 2–3 hours.

Q: Does the granite composite stain? A: Red wine, turmeric, and coffee can stain if left for hours. The composite is non-porous enough for routine use, but wipe up aggressive pigments immediately. Baking soda paste handles most stubborn marks.

Q: Will this fit my existing sink cutout? A: Measure your current sink’s outer dimensions. The Kraus needs a 32.5-inch minimum cabinet opening and roughly 21 inches of depth. If your old sink was a standard 30-inch drop-in, this will likely fit with minor adjustments.

The Verdict:

Buy it if you want the farmhouse look without the expensive retrofit surgery, and you’re okay with the granite maintenance.

Skip it if you’re on a tight budget, hate cleaning water spots, or want a true undermount installation.

The Kraus Workstation Drop-In Retrofit Farmhouse sink earns a 4.2/5. It delivers on its core promise — the farmhouse aesthetic and workstation utility in a drop-in package — but the accessory upselling and maintenance demands keep it from perfection. Solid choice for the right homeowner.

Price check: This sink fluctuates between $350–$450 depending on season. If you catch it under $400, that’s a fair deal. Above that, wait for a sale.
