How to Select the Right Farmhouse sink: Buying Guide
There are many types of farmhouse sinks in the market today. A sink is a long term investment that can either make or break the design of your kitchen.
As such, it is imperative to get it right the first time and we are here to help. We will explain some of the key features to look out for when looking for the ideal apron sink in this section.
They are deeper and bigger than the traditional sinks hence it is easier to wash the bulky puns and pots in them. Also, you can minimize the time you spend on washing the dishes because you will not strain to reach the sink.
Kitchen sink style
Different sinks come with different styles i.e. single sink and double sink. Some even have three bowls!
Let us delve into the details of each sink to help you choose the best.
Single basin sinks:
These have a single basin and are very easy to install. They come in different sizes so you can choose the on that fits your kitchen and preferences well.
They are great for small kitchens and are way cheaper than double basin models of the same size. The sinks, however, are small and can make washing larger dishes difficult when the sink is full.
Double basin sinks:
These are larger than single basin ones but are more expensive. A double sink is better because it allows you to store your dirty dishes on one side and wash them on the other.
The main limitation of these sinks, however, is that the faucet is placed in the middle for most models, which will limit the cleaning of big pots.
It also limits your movement, making you slower and less efficient when cleaning up. However, you can easily fix this by having the faucet on one basin.
Round basin sinks:
These sinks are undoubtedly very attractive but can be limiting when installed as a kitchen sink.
They waste a lot of space and require custom made counters to install. They are mainly ideal as hand washing and brushing sinks.
Getting the right material for your sink is very important. The material will determine the durability of your sink, affect its compatibility with the kitchen colors and decor, and affect the sink's maintenance.
You can choose from a wide variety of sink materials with each coming in different finishes and colors. The most notable sink materials are:
Fireclay is one of the most popular materials for making farmhouse sinks and for obvious reasons. The timeless appeal of fireclay makes for a beautiful setting. It is also durable and virtually scratch resistant.
Porcelain is, like fireclay, a ceramic material heated to extreme temperatures to give it strength and durability. While porcelain is more prone to scratches and chips than fireclay, the surface is much easier to clean.
iii. Stainless Steel
Among the most common sink materials, stainless steel gives a modern look and classy finish.
It blends with most kitchen decors and is very durable. They come with rubber pads to absorb vibrations from your sink activities. This reduces the noise that it produces.
Stainless steel, however, is prone to easy scratching. This is easily solved with a bottom grid that protects it against scratches.
The other limitation is that stainless steel does not hide fingerprints and water stains; they make it look ugly and unkempt.
You can solve this, however, by using a dry cloth to pat the affected areas to make it look clean.
Copper is a material that is increasingly being used to make farmhouse sinks. A copper sink may appear too austere when it is new as many come with a hammered finish.
However, over time, the surface of the copper attains a beautiful patina as it reacts with materials that come into contact with it.
v. Cast iron
This material is highly durable, making it one of the top for farmhouse sinks. Sinks made from this have a porcelain enamel coating, which makes them highly durable.
Additionally, it comes in different colors and does not make any noise when being used. It can resist up to 1000 degrees F, which means that placing a hot pot on it will not damage it.
There are several installation options, including an undermount, flush mount and raised sink. Installing a farmhouse sink is not like installing regular sinks. It has to be supported by reinforcements under it for it to fit and work well.
Most regular sinks feature the top mount installation, which means that the sink is more visible. Most farmhouse sinks, on the other hand, feature under mount installation. This means that they are installed below your kitchen counter.
The sinks, therefore, are more efficient since they are less visible and bulky. When cleaning, you just need to wipe the dirt straight into your sink, which makes cleaning of your tabletops very easy.
Under mount sinks are also ideal for kids and shorter people because of the reduced height of the sink.
Farmhouse sinks are not cheap. Prices vary in terms of the material, the size, and number of basins among other factors.
When planning to buy a cheap farmhouse sink, you need to know that it is not a small investment. As a result, you should choose the one that suits your kitchen needs. Since it is a long-term investment, there is no problem investing extra to get a highly durable kitchen fixture.
Different farmhouse sinks come in different sizes meaning that you have a wide range of sinks to choose from.
Larger farm sinks look appealing but you should only pick them if they are compatible with your preference and available room.
If your space is limited, you can invest in sinks with unique configurations to make them as appealing as the larger ones.
Are farmhouse sink and apron front sink the same thing?
The difference between a farm sink and an apron sink is nomenclature. The two terms are used somewhat interchangeably depending upon what image the user wishes to convey.
Saying, "farm sink" is indicative of a rustic or country design whereas "apron sink" sounds more modern. Regardless of which term that is used there are a variety of materials available for the construction of a farm or apron sink.
An apron front sink has a distinct look because of its exposed front side. They are designed to be easy to replace.
This type of sink has no holes for faucets and fixtures. Instead, the water faucet is routed instead through a permanent fitting location on the counter which extends over the sink without you having to attach it.
This makes the apron sink versatile and ideal for a farmhouse. More and more people are installing apron front sinks because it looks rural and it is extremely useful. The large sink has multiple uses and can accommodate the needs of big families. A farmers sink is most commonly white and is 30 inches wide. There are also stainless steel, copper or other metals as well as soapstone.
Another feature of the farmhouse sink is the open front that shows off how deep it is. Many people love their farmhouse sinks, and they feel like it adds a special touch to their kitchen. You can choose how many of these steps you’d like to try yourself, depending on you skill level, ability, tools and time.
A farmhouse sink is styled after sinks that were designed for homes when people had to draw water from an outside source and bring it inside the home because there was no indoor plumbing available.
A farm or apron sink extends beyond the cabinetry and rests beneath the counter top making sweeping water or crumbs into the sink an easier task. Typically, a farm or apron sink is deeper than what is now considered a "traditional" sink.
The deep basin makes it easier to fill or clean large cookware. Many farm or apron sinks consist of only one basin, however, double basin models are now gaining popularity.
Advantages of Using A Farmhouse Sink
There are tons of useful reasons to install a farmhouse sink. They are very efficient and great for bustling kitchens. They are also easy to replace in case the sink needs to be upgraded. The aesthetics of the sink are in style right now, and it adds a rustic charm to any farmhouse or home.
The larger size allows pans and pots of bigger sizes to more easily be accommodated in the sink. They are also closer to the edge of the counter. This makes clearing dishes and leaning over less of a burden for the homeowner. Back in the day, before this modern era, many more pots and pans were used in the kitchen. These deep farmhouse sinks fit them easily.

Fireclay Sink vs Stainless Steel Sink: Which is better?
Fireclay sinks are types of ceramic sinks. Clay is carved into the shape and size of the sink then molded at mild temperatures for 2 days. When dry, porcelain enamel is applied on the farm sink and then put in a kiln and heated to 2000 degrees F for almost 24 hours.
The high temperatures allow the enamel to fuse into the ceramic, thus increasing the strength of the farmhouse sink. They have a vintage appearance and are highly durable. Fireclay sinks have a rough craft quality and can be molded into any shape. Stainless steel farmhouse sinks, on the other hand, have to take a specific shape as designed by the manufacturer.
Fireclay sinks are very quiet since the enamel does not let out a lot of noise. Unlike the fireclay sinks, stainless steel sinks are very noisy when pots and dishes bang against them.
The hard enamel on fireclay sinks is resistant to scratches and stains, which makes maintenance very easy. However, harsh abrasive products can scratch and dull the basin.
Dishes and pots can also chip the enamel of the sink. Stainless steel is also very handy when it comes to durability. It lasts for a long time but is not resistant to scratches, fingerprints, and water stains. A farm sink grid can help prevent this by preventing knocking of the finish by your pots and pans. It also adds to your storage space.
Despite all these great features, fireclay farmhouse sinks are limited in color and finish. They are mostly off-white and white. This compares poorly to stainless sinks that can be colored as you desire.
Additionally, stainless steel farm sinks are easy to manufacture, install, and are affordable as compared to fireclay sinks. Another limitation is the installation process, which might require a professional contractor.
Fireclay farmhouse sinks are very heavy and feature complex plumbing conditions that can be hard to figure out on your own. Stainless steel sinks, on the other hand, are very easy to install and will rarely require the services of a professional contractor.
How to clean and maintenance of your farmhouse sink:
Living in a farmhouse brings the best of country living and comfort to the farmhouse inhabitant. In the country, the morning air is crisp and clean, with faint aromas of spring flowers or freshly harvested crops in the fields nearby.
If you happen to be the lucky inhabitant of a farmhouse, you undoubtedly have experienced both the hard work and relaxation that living in the country brings.
The farmhouse lifestyle can be messy, and typically requires cycles of toil and cleanup as seeds are planted in the garden, animals are tended to, and vehicle repairs are made. Tools and equipment on farmhouse grounds may become extra dirty and need to be cleaned on a frequent basis. Gardening hand tools, rubber boots, planter pots and containers, textiles- all are examples of objects that may need to be frequently cleaned up after use on a farm.
Eventually, after several weeks or months of heavy use, you may find that it becomes necessary to deep clean your farmhouse sink. After all, you need it to be clean enough to produce the results you want, and not contribute to the mess! If you find yourself in this situation, here are some helpful step-by-step instructions:
1) Assemble your cleaning supplies. You'll need a good abrasive cleaner like Comet, Ajax, or an all-natural substitute; a scrub brush with strong bristles; scrubbing pads or steel wool; and depending on whether or not there's grease in the sink, you may need dish liquid or another type of grease-cutting surfactant.
2) Remove all large and small loose debris that may be left in the sink. This includes dirt clumps, rocks, sticks and leaves, shells, pebbles, etc. If there is any stuck-on adhesive material, remove anything that's loose- but don't stress about removing all of it, just yet.
3) Do a pre-rinse of the sink and wash away any remaining loose dirt. This should leave you with a relatively smooth surface, which is a great place to begin scrubbing.
4) Clean the sink with your cleaning solution and scrubbers or brush. Sprinkle the abrasive cleaner into the sink, allowing it to coat the entire surface of the sink. Add a little water and use the scrub brush to begin scouring away the dirt and stains. If the sink is deeply stained, you may need to pause and let the cleaner soak in for a few minutes.
5) Rinse, inspect, and repeat. When you have finished scrubbing the entire surface of the sink once, rinse the sink and see if all the stains and dirt have been removed by your efforts. If there is still dirt or ground-in stains, repeat the cleaning steps above, and maybe allow the cleaning solution to soak for a longer period. You can do this as many times as you need to!
It will take a little time and effort, but when you're finished cleaning your farmhouse sink you'll be free to use it without worrying that it will contaminate anything you're trying to clean.
#1. Caring For Fireclay And Porcelain Sinks
Unlike sinks made from cast iron, fireclay sinks are more resistant to stains, scratches and abrasive cleaners. Fireclay does not contain any metal. Therefore, it is rust proof. Additionally, aggressive food particles that can easily stain your sink can be wiped away.
To care for fireclay and porcelain sink;
- Use a soft cloth and mild cleaners when cleaning your sink.
- Wipe the sink with a soft rag to avoid water spots.
- Gently place the heavy pots and dishes on the sink to prevent it from chipping or cracking.
- Use a rubber mat to protect the bottom of your sink.
#2. Caring For A Stainless Steel Farmhouse Sink
- Dry your sink with a soft rag after washing the dishes to prevent water mineral spots.
- A stainless steel pad will mat the finish on mirrored, shiny or highly polished surfaces. Therefore, it should not be used.
- Keep your sink free from standing water because this water will lead to a build-up of mineral deposit on the sink and cause it to appear dull.
- Remove stubborn stains using a mild abrasive and by scrubbing in a circular motion to preserve the sink’s finishing.
- Do not leave steel utensils, cookware or water spots for a prolonged period. Utensils made from iron can leave rust spots on your stainless steel sink.
- Never use steel wool or scouring pad to clean the sink because it will discolor your sink.
- Do not use cleaning agents that contain hydrochloric acid or sulphuric acid because they will damage your sink.
- Never leave salt, mustard, mayonnaise, citrus fruits or pickles in the sink for a prolonged period because they will wear down the surface of your sink.
- Lastly, do not leave cleaning pads, rubber mats or sponges for an extended period because they will trap water and discolor or stain your sink.
Frequently Asked Questions:
1. Are farmhouse sinks durable?
ANSWER: Durability of the farmhouse sink depends upon the material that is used to manufacture the piece. Porcelain sinks, while beautiful, are slightly less durable because the material may chip or crack more easily.
Fireclay is a beautiful material that is similar in appearance to, but more durable than, porcelain. Other materials to consider are copper and stainless steel.
2. How deep is a farmhouse sink?
ANSWER: There is no standard measure for the depth of a farmhouse sink. It all depends on the design of the manufacturer and your choice as the homeowner.
On average though, a farmhouse sink is about a foot deep. It can be substantially deeper than this or slightly shallower.
3. Can I have a farmhouse sink with two compartments?
ANSWER: Absolutely. The sheer variety in the design and appearance of farmhouse sinks mean there is plenty to pick, including double compartment alternatives.
4. What causes low water pressure in a farmhouse sink?
ANSWER: Owing to its sheer size, filling up a farmhouse sink requires that water is running at considerably high pressure. The faucet of a kitchen sink is usually set high into the wall and this is a chief reason why the water can run at low pressure.
But you should still check the plumbing in and around the kitchen to ensure there are no leaks.
5. What is the best material for a farmhouse sink?
ANSWER: Again, the answer to this is all hinged on your preferences as well as the styling and decor theme of your kitchen.
Ideally, the best apron front sink should be appealing to the eye, functional, and durable. They have regained popularity as a design element in the kitchen.
It is easy to figure out that the best farmhouse sink is Latoscana 33" Reversible Fireclay Farmhouse Sink. It features a beautiful Italian-made reversible design, which played a huge part in my decision. I also love how the sink is elegantly finished on each side.
