There are many things to take into consideration when selecting a kitchen sink.
All bench materials can use topmount sinks where the sink is installed above the bench top. Solid surface bench tops can use either undermount sinks, where the sink is installed below the bench top or flushmount sinks, where the sink is installed so that the sink and bench top sit flush.
Depending on your kitchen design and personal preference, select how many bowls you want, how many drainers if any and if you require the bowls on the left or right hand side.
Your bowl size can depend on your lifestyle. A chef will need bowls large enough and deep enough to fully immerse baking trays, while others may just need a bowl size big enough to was the dishes too fragile for the dishwasher.
Check your cabinet is wide enough (left to right) and deep enough (front to back) to accommodate the bowls of your sink.
Pressed bowls are made from drawing the bowl's shape out of stainless steel while fabricated bowls are made by folding their shape and welding it's sides. For a quality pressed bowl sink ensure it is manufactured from at least two sheets of stainless steel.
Edge Roll/Micro Edge
When selecting a topmount sink, a rolled edge gives a traditional look, while a micro or bevel edge gives a seamless, minimalist look.
Sinks can be manufactured from different thickness stainless steel, generally the thicker the steel the more expensive the sink becomes. Sinks can come in polished, brushed or coloured stainless steel or even porcelain, black glass or granite.
Tap Hole Options
Make sure your sink selection can accommodate any additional accessories you may want such as filter taps or soap dispensers. Either the manufacturer or the installer can punch/drill the additional holes as long as your sink as the strength required.
Quality rolled edge sinks are fitted with a continuous foam gasket seal which ensures a water tight installation of your sink.
Particularly for large, deeps sinks look out for soundproofing which is applied to the underside of the bowl to reduce noise and retain water temperature. Wood backing boards on the underside of the sinks drainer can also assist in reducing noise.
Ensure your sink is supplied with Australian Standards certified basket wastes. Modern basket wastes are easy to use with a pull up to strain and drain, push down to seal capability. Look for sinks with rear wast outlets which provide more usable cupboard space below your sink and ensure they are suitable for use with garbage disposal units.
