Kitchen Sink FAQ

Kitchen sinks are such an important part of your kitchen as it sits along your countertop, the best type of sink is one that aesthetically suits your house's theme as well as being highly functional. The best example of this is an Undermount  Stainless Steel Double Bowl Sink. the reason for stainless steel is that it is always neutral and timeless, it doesn't stand out too much and avoids being the centrepiece of a modern kitchen which could end up becoming dated and require replacing.

Why would you choose Stainless Steel kitchen sinks?

At BuildMat we would recommend choosing a stainless steel sink over something like cast iron, granite sink or even farmhouse sink. These are popular when trying to match a theme or popular in other countries outside of Australia. The best kitchen sinks suit your functional needs and the aesthetics of your kitchen.  

- Farmhouse sinks have an apron front, some think that this is appealing, but they don't realise it cuts out a large section of your cabinetry as well as your countertop which would eventually stick out like a sore thumb. In America, the farmhouse kitchen sink is popular and made by brands such as Kraus, Blanco, Franke but they are not as common in Australia because the apron sinks stands out too much in the kitchen.

- Cast Iron sinks are made with a durable iron alloy and are covered with porcelain enamel. because of this enamel what could happen is that it could chip or wear away, these sinks are generally thicker which would mean that it would have to sit as a top mount rather than an undermount sink, fireclay sinks are very similar but more durable but end up being fairly heavy and expensive.

- Granite sinks are currently in trend and can be considered to be more heavy-duty, the main flaws of a granite sink are it's bulkiness because it needs to be made into a thick mould it is extremely heavy and the kitchen cabinets must be designed to hold it's weight. Itis also considered one of the more expensive sinks 


Square or round edges?

All Zen hand-made stainless steel sinks are formed with either bent square edges or rolled round internal edges. Round edges do make it easier to clean and allows for better water flow. Some prefer the slick modern look of the square sinks whereas others prefer the smooth rounded edges. Your call!


Undermount, Overmount or Flush mount?

The benefit of having your kitchen sink undermount is that the sink lip is disguised and bench scraps can be pushed straight in rather than get caught on the lip. This makes it easier to clean. If you're planning to have a stone or granite benchtop an undermount kitchen sink Again, in terms of aesthetics, it’s personal. All Zen kitchen sinks can be installed as overmount or undermount.

Overmount and Top mount are the same types of installation, it is a much cheaper option alternative because the cut out for the sink doesn't need to be perfect because it is not visible, whereas for an undermount sink the stonemason would need to smooth out the edges so that it is nice and clean. Cheaper sinks such as a pressed stainless steel sink are generally come as a top mount sinks and cannot be undermounted, often they are referred to as a drop-in sink because they just drop straight into the cut out.  

You should always check if the sink you're planning to purchase has the correct mounting hardware, as each mounting style will require different types of clips on the sink. BuildMat kitchen sinks come with undermount, overmount and flushmount mounting hardware.

Single Bowl or Double Bowl?

Double bowl sinks have a partition down the middle and assist in separating dirty and clean dishes, separating dishes with food. Whereas a single bowl sinks are more useful for washing large pots and pans. So generally there are more options on how to use a double bowl sink in comparison to a single bowl. When choosing your sink style also consider where the sink will be located, for example in a laundry there would be more uses for a large single bowl sink such as soaking your laundry, washing your dog or pets or even washing your baby which wouldn't be as easy in a double sink because it'd be much easier in a large basin.

1.0mm, 1.2mm or 1.5mm Thick Stainless Steel?

All of our Buildmat Kitchen Sinks are made with 1.5mm thick (16 gauge) 304-grade stainless steel, you will notice the high-quality and sturdiness just by picking up the sink and feeling how heavy it is compared to competitors.

Hand-made stainless steel sinks in Australia generally come in 19 gauge (1.0mm thick) or 18 gauge (1.2mm thick) stainless steel. If you plan on using your sink a lot, the 1.2mm is considered a more durable sink but it is also more expensive. BuildMat would not recommend any sinks less than 1.0mm thick as they are prone to long-term wear a lot easier and sooner. Our 

Some competitor products try and advertise 3.0mm thick sink where they have just made the lip thicker but then used a 1.0mm on the actual sink, this is to try and confuse customers of a superior product but in fact, the bulkiness of the lip can actually trap more gunk along the lip.


If you are getting a kitchen sink, it always pays to get one that comes with some decent accessories such as an insert chopping board, roll mat, dish drying rack, drainer and colander. Especially if you are tight with space, custom-sized kitchen accessories can save valuable bench space in the kitchen!

SS304 or SS316

Stainless steel 304 is the grade of steel required for food preparation and the most common grade used for domestic sinks, it is also known as SS304 and can be also used for commercial-grade kitchens. For hospital use or for use in external areas subject to high salt and acidic content, use the SS316 which is the marine grade stainless steel.


Do I need sound pads or anti-condensation paint?

Yes! When you get your sink, flip it upside down and ensure it has;

a) at least 1 sound absorbing pad on each external face including the bottom where the drain is

Sinks that do not come with sound pads will end up being quite loud when you put your dirty dishes in the sink or even when you're filling it up with water the pads will help absorb the vibrations from the sink to help reduce the sounds from your activities with the sink.

b) a painted coating applied to all areas of the external face that prevent condensation on the underside of the sink.

When storing cold items or even water it is common that condensation may occur on the other side of the sink inside the cabinet, and this condensation could cause a major headache over time, after a long period it could start to rust or it could drip into the wooden cabinet and warp the insides, so it is important that the sink has an anti-condensation undercoating. The undercoating is a normally dark colour and you will be able to tell if it has it because you won't see the exposed stainless steel.


Other Things to Consider When Looking for a New Sink

Faucets or kitchen taps are a very important part of the planning process of your new kitchen, the type of faucet that you will choose can completely change the look of your kitchen and can also dramatically assist or compromise the practicality of your kitchen.
