Kohler Neoroc vs. Blanco Silgranit: Which One Is Better?

Composite sinks are an exceptional choice for any homeowner looking to buy a durable sink. The popularity of composite granite sinks makes sense – they’re cheaper than solid granite yet offer many of the same benefits. Granite composite sinks are widely available in varying configurations, colors, styles, and designs. 

Several brands, including Kohler and Blanco, offer composite granite sinks. The Kohler Neoroc and Blanco Silgranite composite sinks are at the forefront of the industry, and for a good reason. However, most kitchens don’t feature two sinks, so most homeowners have to pick one. So, is one better? 

Kohler Neoroc

Kohler is a well-known brand in the industry. The company produces numerous high-quality kitchen and bathroom fixtures, including sinks and faucets. While the products tend to lean toward the pricey end of the spectrum, Kohler does offer a few budget-friendly options. 

There are thousands of kitchen sinks available in the market, so the competition is fierce. Despite the abundance of options, many homeowners continue to choose the Kohler Neoroc sink for their kitchens. 

Hundreds of reviews applaud this particular model for multiple factors, including its durability, appearance, and overall quality. It is worth noting that there are a few unhappy reviews from customers stating their sink feels more like plastic than stone and scratches easily from silverware. 

Despite the bad reviews sprinkled in the mix, most customers seem happy with the overall product. Kohler offers Neoroc sinks in several configurations, including single-bowl and double-bowl designs. The sinks primarily come in black and white, but there are a few other colors available. 

Kohler offers a lifetime limited warranty on its Neoroc sinks, ensuring each product will be free of defects in material and workmanship in a typical residential setting under regular use. This warranty extends as long as the original purchaser owns the home. In a commercial environment, the warranty shortens drastically to one year from the date of purchase. 

What Is The Kohler Neoroc Sink Made Of?

Kohler’s Neoroc sinks are made of strong, durable composite materials. Like most granite composite sinks, these products are made with a mixture of stone and resin. The final product is highly resistant to impacts, stains, fading, and heat.

Blanco Silgranit

Blanco is another well-known brand in the industry, although it isn’t as much of a household name as Kohler. The company produces multiple quality product lines, including its Silgranit sinks. These sinks regularly make the list as one of the best kitchen sinks, so Blanco is known for this particular material. 

These sinks are incredibly solid and well-made, making them a popular pick for busy homes. Silgranit sinks are scratch and stain-resistant, hold up well under high heat, and are easy to clean. Harsh chemicals can damage the surface, so you need to steer clear of those. Instead, all it takes to clean a Silgranit sink is mild dish detergent and warm water.

Blanco offers a wide range of Silgranit sinks, with over 30 styles and 8 color options available today. There are single-bowl and double-bowl configurations to meet the needs of almost any kitchen. 

Like Kohler’s Neoroc sinks, Blanco Silgranit sinks boast hundreds of excellent reviews across numerous platforms. The majority of reviews are top tier, with many customers raving over the aesthetics, durability, and price point of these sinks. 

Of course, there are a few negative reviews scattered throughout. The few negative reviews mention issues with scratching and chips after a few years of owning the sink. 

Like Kohler, Blanco offers a solid warranty program for its Silgranit sinks. The company warrants its products will be free from all proven manufacturing effects in material and workmanship. For interior single-family domestic applications, the warranty is a limited lifetime. The warranty shortens to five years if the product is used in a multi-residential setting. 

The warranty shortens even more in commercial settings, extending three years past the original purchase date. 

What Is The Blanco Silgranit Sink Made Of?

Blanco Silgranit sinks are composed of crushed granite and resin. Like any good-quality composite granite sink, these sinks feature a high percentage of natural granite. The sink is made up of 80% natural granite (quartz sand) combined with 20% acrylic resin. 

The result is a solid, non-porous surface that repels liquids. Unlike natural granite, you don’t need to seal these sinks after purchasing one. They’re resistant to heat, stains, and fading. The manufacturer casts these sinks in a single pouring, so the sink is pigmented all the way through. There shouldn’t be any issues with fading or color changes.

  • Heat resistant up to 536 degrees F

Pros And Cons

The Blanco Silgranit sinks, just like any other product, have a few pros and cons. A few notable advantages and disadvantages to consider include:


  • Easy to clean
  • Available in several colors
  • Variety of styles and designs
  • Durable
  • Long-lasting
  • Beautiful appearance
  • Lifetime limited warranty
  • Resistant to heat


  • Susceptible to chips and scratching
  • Can be pricey

Which One Is Better?

Narrowing down the best kitchen sink option for your home can be tricky. If you’ve narrowed it down to specific material, like granite composite, you’re almost there! Now, you just need to pick the perfect brand and model for your kitchen. 

If you’re stuck between Kohler and Blanco, you’ve narrowed it down to two solid options. As you make your decision, weigh the pros and cons of each brand’s granite composite sink. Additionally, it doesn’t hurt to comb through customer reviews on each option. After all, these customers have first-hand experience with the specific sink you’re interested in. 

As we browsed through information and customer reviews while creating this article, we noticed a few more positive reviews on the Blanco side. In terms of overall quality, customers seemed to like Blanco’s Silgranit sinks better. A few customers who had bought Kohler’s Neoroc sinks mentioned the quality of the sink pales compared to Blanco’s Silgranit. 

However, hundreds of positive reviews exist on both options, so it’s hard to go wrong with either option. Once you make your pick, be sure not to void the warranty by buying the sink from a third-party distributor. Both manufacturers offer limited lifetime warranties on their sinks, but buying the sink from certain places may void this warranty. 

So, before buying the sink, make sure the warranty is valid through the distributor. 

Which One Should I Buy?

Ultimately, the choice is up to you. Both options are excellent choices, especially in the grand scheme of composite granite sinks. Both selections boast outstanding reviews, solid durability, and a reasonable price point. 

So, it comes down to what you’re looking for. Blanco and Kohler offer several options, so you shouldn’t have any issues finding something you like. For example, if you want a few more color options, you might find something you like in Blanco’s lineup. Or, maybe you’ll find a Neoroc configuration that works perfectly for your kitchen.
