How to Measure a Kitchen Sink

In this article we show you how to measure your existing sink and worktops, in preparation for installing a new one.

Measuring the Sink

It’s important for you to know just how big your old sink is, along with the hole in the worktop your sink sits in. This allows you to install a new sink with as few modifications to your worktop as possible. You don’t want to end-up buying a sink that is either too big or too small for your space!

Start by measuring the length and width of the sink. Run your tape measure from one edge of the sink to the other in a straight line. Then write down the measurements that you find.

To accurately measure the depth of your sink, take a ruler and lay it over the top of the sink. Then measure from the bottom of your sink to the top of it.

If your current sink is an undermount one, don’t forget to take the thickness of your worktop into account when you’re taking your measurements.

Use your final measurements as a guide when buying a new sink. You will need to get a sink with a similar height, width and depth to your current one. You’ll also need to measure the worktop hole your sink sits in (or under.)

Once you’ve finished measuring the sink, remove it from your worktop and measure the length and width of the worktop hole. By choosing a sink that fits in this hole you can save yourself having to extend the hole at a later date.

Remember that most inset sinks will have a lip at the edge that will extend over the edge of the worktop hole.

Installing a New Sink

  • Once you’ve picked your new sink and received it, it’s time to get it installed! Use these tips to make the process as simple as possible.
  • Take a picture of your current plumbing configuration before you remove anything. This will allow you to put it back together more easily later on.
  • You will also need to disconnect the water before you remove or install anything.
  • Use an old bucket or pan to catch drips when you’re unscrewing pipes.
  • Many sinks will be held in place with metal clips and caulk. Use a screwdriver and utility knife to loosen these and make removing the old sink easier.
  • You can remove the old sink and tap at the same time, but make sure you attach the new sink before the new tap.
  • You can avoid water damage by coating the edge of the worktop hole with a waterproof sealant. Leave it to dry before installing the new sink!
  • To position your new sink on the worktop properly, use a bead of silicone along the cut edge. This will ensure a neat, accurate fit.
  • Don’t forget to secure your new sink with the included clips.

 

Caring for Your Sink

At Kitchens InStock we provide several different sink materials. Each one comes with different advantages, and must be cared for in a different way to ensure a long-lasting and beautiful sink!

 

Stainless Steel

This timeless material will be right at home in a range of kitchen styles. It’s also available at a low price, meaning anyone can add an attractive stainless steel sink to their kitchen.

To keep your stainless steel sink looking its best, do not use abrasive pads or cleaners (like bleach) on the material. Avoid using any metal cleaning implements like scouring pads as well.

You should also avoid leaving water standing in the sink for a long time. If you do, this can cause unsightly mineral deposits to build up on the material. Toweling the sink dry after use will stop water marks appearing.

Keep in mind that most stainless steel sinks will acquire minor scratches from everyday use regardless of how careful you are. These won’t affect the sink’s function or sturdiness, but it will give your sink a unique finish. If you want to make these scratches less noticeable you can use a stainless steel polishing cream on the sink.

 

Ceramic

Ceramic sinks offer a clean, classic look that’s right at home in rural or traditional kitchens. However, they also come with modern styling if you want a more contemporary look.

Clean a ceramic sink with hot soapy water and a soft cloth. Like stainless steel, ceramic sinks are at risk from mineral deposits being left on the surface. These, in turn, soak up coffee, red wine and other staining foods. You can avoid this by rinsing and towelling dry your sink after you’ve used it.

Ceramic sinks can be chipped, cracked or scratched if treated roughly. To prevent this from happening, avoid dropping sharp knives or heavy pans on the material. You should also refrain from using plastic washing up bowls in a ceramic sink. This is because grit and glass can become embedded in the underside, which can then scratch the ceramic.

Do not expose the sink to extreme temperatures, or hot and cold temperatures in quick succession. This is because ceramic expands or contracts with changes in temperature, which could crack the material if it’s placed under too much stress.

 

Composite

Composite sinks uses a mix of different materials (including granite) to create an attractive, hardwearing product. The material is highly resistant to stains, scratches and extremes in temperature. They also come in a variety of colours and styles, giving you many different options for your kitchen.

To clean a composite sink, wipe it down after use with hot soapy water and a soft cloth. If any limescale or other mineral deposits build up on the material, you can use a mix of water and white vinegar to loosen them. However, do not leave this in contact with the sink for an extended period of time. Drying the sink after use will prevent mineral deposits forming in the first place.

Stronger cleaning products like bleach and metal scourers should be avoided at all costs.

 

Glass

These sinks combine a toughened glass drainer with a stainless steel bowl. The resulting combination is an excellent choice for modern homes.

The glass drainer can be cleaned with a regular glass cleaner. You can then use crumpled newspaper to dry the glass and shine it. Clean the stainless steel bowl as normal.

We recommend drying the sink shortly after use to prevent the buildup of limescale and other mineral deposits.

 

Granite

These sinks use powdered granite combined with other materials to create a very sturdy, hardwearing product. The material is resistant to cracks, dirt and even food stains such as coffee and red wine.

To clean a granite sink, wash it after use with hot soapy water or washing up liquid and wipe it dry with a soft cloth. If you encounter any dirt or ground-in stains, you can use heavily diluted dishwasher detergent to loosen them.

Although granite sinks are very hardwearing they can become dented or chipped. Therefore, avoid dropping heavy objects or sharp knives on the sink during use.
