Buyer’s Guide For The Best Undermount Bathroom Sinks

---

Inasmuch as bathroom sinks or lavatories may not require much stress unlike kitchen components, they’re also just as important and as such require adequate attention in order to properly set them up. True you’re set on getting yourself a nice bathroom sink to suit your fancy, here’s the information you need to make the right choice.

Types of Bathroom Sinks:

Pedestal Sinks:

From their name you know they’re standing sinks that are attached to a small column underneath. These ones are not placed in a vanity, rather they standalone and allow for movement in a small-sized bathroom.

Self-Rimming Sinks:

These look like the regular under-mount sink, but they’re in fact different. These ones are fixed above the top of the counter and they have a finished rim that keeps them firmly in place above the countertop. It’s one of the easiest sinks out there to fix and remove.

Vessel Sinks:

these sit on the vanity counter such that the base of the sink is aligned to the top of the counter. It gives room but not so much.

Under-mount Sinks:

These are the ones this review is about. They’re great for creating space in the bathroom, are made out of tough materials such as granite, concrete or marble, and they allow for customizing the countertop – which can pose a serious task when removing/replacing.

Although there are a lot more sinks to check in the market, here are the main things to consider:

Sink Materials:

Different bathroom sinks are made up of different materials, and the materials used to make them goes a long way in determining their durability. You have to be sure that the material is durable and how much maintenance would cost for the bathroom sink you have in mind.

Vitreous China:

These are porcelain sinks that have close similarities with other clay ceramics in the market. They’re beautiful on the outside, easy to clean and very resistance to stain. But they’re susceptible to crack when hit with a hard and heavy object.

Metal Sinks:

These are made of a variety of metals. They could be stainless steel, copper or brass, and are very durable (they can withstand heavy impacts). The sad news however is the fact that they’re susceptible to stains – due to exposure to water overtime, rusty spots would start spreading all over the surface.

Solid Surface Sinks:

Are made out of the same material as countertops (granite or marble). Although they’re easy to clean and are durable, they can crack easily. But that can be resolved by patching. Sinks made out of solid materials such as granite and marble are ideal for conventional bathrooms that are more concerned about functionality over style.

The fact is that, there is no ultimate sink material. Go through the material used and make your choice based on your preference.

Sink Sizes: 

​Different bathrooms come with different sizes, and the sizes go a long way in determining what sink should be in the bathroom. You can put a large sink in a small bathroom, and it definitely would be out of place to put a small sink in a big bathroom. To ensure you get the right sink, check your bathroom size, and compare with the sink’s size.

Another thing to note about sink and bathroom sizes is the arrangement. Your bathroom might be big yet the arrangement makes it look small thus forcing you to get a small sink. But with a bit of readjustments, you might not need to buy a small sink, it all depends on you.

Bathroom Traffic: 

​Funny as it may seem, knowing how many persons would be using the bathroom is necessary to pick the right sink. You surely don’t want to have a small single user sink when you have a big family and relatives staying around.

If it’s a private bathroom just for you, then by all means save cost and space by getting one that fits your size, and you can spice up your taste by getting stylish sinks made of delicate material. But if it’s a big house with tons of persons trooping in, a low maintenance yet durable sink would be most ideal. All in all, be sure to get quality for your money.

Frequently Asked Questions (FAQs).

How are under-mount sinks attached?

They are usually attached with two-part epoxy adhesive. It is then sealed with silicone caulking around the perimeter. Do not leave spaces when caulking because it can be the source of breakages. Always hire a professional to do it for you in less than half an hour!

Is it necessary to have faucet holes for the under-mount sink?

No, it is not necessary. There is no accessible rim on an under-mount sink, unlike an over-mount sink that must have one. This, therefore, means that you have to drill holes for the faucet in the countertop. A faucet can be fixed here and this is the point where water will fill the sink.

Do you need special faucets for the under-mount sink?

No, you do not need special faucets for this type of sink. The normal faucets can be used on them as well. It is only that the sink does not have faucet holes, and as we have seen, you have to drill holes on the countertop. You can even pluck a faucet from on over-mount sink or the normal kitchen sink and use it on an under-mount sink.

How far should the tap be from the under-mount sink?

The best distance would be around 50mm. This is the distance between the sink and the opening of the tap. Whenever possible, you should provide an extra 10mm difference to cater to the tolerances in the sink manufacture. This means that a 60mm distance is even better.

How do you size an under-mount sink?

Most standard under-mount sinks measure 22 inches by 30 inches. The countertop, however, may dictate how large or even small the under-mount sink can be. You then, have to decide how many bowls the sink should have and how deep you want it to be. This will give you the correct measurement of how the sink will be.

How do I choose an under-mount sink?

Several factors will come into play here. First, you have to consider the type of countertop you have. Ensure that the edges around the sink can be done some finishing. When the sink has been inserted, then some final touches on the edges has to be done.

Self-rimming sinks, on the other hand, have rounded corners. They can, therefore, be mounted on the countertop material with a lot of ease. Such sinks do not require a lot of finishing, but a little of it can be done.
