Let’s find the best undermount kitchen sinks!

What makes an undermount so special? Mainly, how it is installed. This type of sink is attached to the underside of your counter instead of sitting over it, as the more common overmount units do. As there is no exposed rim, the sink blends right in with your counter; you also get to sweep any food scraps or spills straight into the bowl. However, such a setting doesn’t happen easily: there are several factors to take into account before even starting to shop around. What makes the best undermount kitchen sinks?

Undermount Sink: Not For Every Kitchen!

As attractive as they are for their sophisticated look, committing to this type of sink is no simple matter: it is important to take a hard look at your counter and decide if this truly is the right fit for you.

DIY, yay or nay?

Unless you happen to be a professional with plenty of experience on this specific type of installation, the answer to this one is nay! While a conventional unit needs only be dropped into the counter slot and then hooked up, an undermount requires thorough attention to detail. You really, really don’t want to wing it! Aside from having to create special holes to install your faucet, weight is much more of an issue, which brings us to the next point.

Is my counter strong enough?

If it is tile, laminate or similar, then the answer is no. Sinks are heavy, especially when loaded with dishes, and materials that are not solid enough will be easily defeated by gravity’s pull. Can you imagine your sink and your favorite dinnerware set, crashing down on the floor? That would get very, very messy!, which is why it is important to pay attention to your pick of material. If you’re choosing your counter’s make as we speak, go for granite, concrete, or marble. This is the sort of resilience you want if you are seriously thinking of getting an undermount sink into your kitchen.

Is There Enough Space?

An undermount sink will be sitting about an inch lower than a drop-in, which means the bottom will also be lower, and so will be anyone who works on it once installed. It is a good idea to do measurements prior to putting the sink in, so as to be sure there will be enough maneuvering space.

Can I afford it?

This is a big factor! Undermount units tend to be more expensive than overmount; same goes for marble or granite counters. Installation is more complicated too: your sink must be secured very firmly, no room for error; and special holes must be made on your counter or wall for your faucets. All of this doesn’t come cheap! Better to be sure that your budget can take the hit before you take the plunge. The best undermount kitchen sinks won’t be cheap, but they’re definitely worth it!

There is one more thing you should remember: given how thoroughly they are affixed to the underside of your counter, and since the installation holes are custom made for your model, replacing a sink of this type can get complicated! Once you go undermount, you can’t easily go back.

What Sets One Sink Apart from the Other

So you’ve done the numbers and taken the measurements. You’ve talked it over with your partner and/or family. Undermount is a go, and shopping can begin. Here are the ways in which a sink is different from the rest, so you can make the best choice for your taste and needs.

Bowls: Number and Size

Besides the well known 1 and 2-bowl choices, there is a not so known difference: proportion. The most common version is 50/50 —that is, bowls are of equal size. There are, however, 60/40 and 70/30 options. If you regularly find yourself dealing with larger pans or baking sheets, you might want to choose a sink with one bowl that can fit your bigger items comfortably.

Divide: Full or Low

Full divide is what most of us are used to seeing: the barrier separating the bowls is as high as the outer walls. Low divide, standing only half as tall, is a relative newcomer. An obvious drawback is, you can’t fill up the bowl to properly soak your larger items, and water from one bowl can easily splash into the other; some, however, like being able to work with larger pans across the whole sink, while retaining the ability to soak medium and small items in the two bowls. The choice here comes down mostly to individual taste. But when it comes to the best undermount kitchen sinks, there’s more to consider.

Material: Weight, Noise & Durability

Undermount sinks are made in a variety of materials, and with every material come individual perks and challenges. Stainless steel is quite durable and comes in different degrees of thickness, measured as gauge (the lower the number, the better). Thinner is cheaper, and also noisier; you might want to consider a unit that includes deadening pads or undercoating, as every contact between your pans and the sink could get very loud.

Cast iron is also very durable. Copper has a very unique look that many find attractive and which even changes with use, but it comes with a potential risk of copperiedus, or copper toxicity. Fireclay is fairly resilient and can even take high temperatures, but it can crack if not used with reasonable care. And composite granite is among the fanciest-looking options you can find, but it is also remarkably heavy, and it can develop cracks if it takes too many hits. The aesthetic you have in mind, as well as your particular needs, will be relevant when settling or a particular material.

Finish will play a part here as well: Your sink gets a lot of friction on daily use, and the longer it stays without scratches, the better!

Bonus! Format: Conventional Or Farmhouse

For those who love echoes of the past, farmhouse style is inspired by the large sinks needed on those days when there was no running water and the sink had to hold a big quantity. A sink of this type can be quite a head turning feature on your kitchen, and a massive boon to certain design themes. Their size, however, is their main downside: farmhouse sinks remain a bit of an oddity and most counters won’t be designed with them in mind. The best time to plan for a farmhouse sink is when laying out the kitchen.

Now that you know their defining features, let’s take a look at our selection. Just don’t forget to measure your counter first!
