Supporting frames cutting

  • Farmhouse sinks are a bit heavy than standard sinks, so make sure your cabinets should be strong enough to hold them with ease.

For this:

  • You should have few wooden bars
  • Cut them according to the measurements, 
  • Mark the marks on them with the pencil,
  • Place the supporting bars on them in the right place by putting them in the holes you made with an oscillating saw.
  • Now attach the wooden supports on the bars so that the bars can hold the weight better.

The size of them should be 2’’X4″, and there should be a cross piece because a little more support can be useful to strengthen the entire structure.

Cut out the cabinet front:

  • To install the full front of the sink and the cabinet, you need some adjustments. 
  • Suppose you have any confusion about the correct size of the front portion that is to be cut and adjusted. 
  • In that case, the supports you are available with the sink will help you understand the measurements very quickly to get the sink fitted with the hand saw.
  • You can also use the jigsaw for this purpose. If you want to get smooth shape without any professional help, the machines can do the same and give you a soft look as the professionals can do in this task. But the uneven surface will stay under the sink that will be the main problem.
  • The proper space you can give below the sink is about 5 to 8 inches from the top counters. Also, the size of 4X 4 can be helpful.

  • It will be a perfect fit if you have done the cutting and adjusting process correctly according to the size.

Place the countertop back in the position:

  • When you assure that the sink is in a perfect place and fit, installs the countertop back on the position. Moreover, if you want to replace the countertops with different materials, you can also do that. 
  • Several kinds of materials are available in the market, such as Granite, Rock, soapstone, decorative lamination, tile, and wood. But in my opinion, wood should not be used as water can spoil it all the way.
  • So it will be better to use any other material, in which the risk of damage is comparatively less.
  • So this is the complete story about it; you might think it would be easy to hire professionals. But doing it yourself gives you a sense of self-confidence and can save your money too.
  • You can also do the same process if you want to replace the under-mount sink with the farmhouse sink. Only you have to follow the instructions carefully.
