How to Replace an Undermount Kitchen Sink

Today we are removing a cast iron sink and installing a stainless steel sink.

You want to read the instructions that come with your new sink to get a really good understanding on what’s involved.

Also there are some really good use and care hints that your going to want to read through.

So the firs step is to remove the existing sink and with a cast iron sink, it is extremely heavy and the problem that we had is that you have to remove the sink from the bottom.

We could not cut out the corian and lift the sink straight out, so we are using that 2×4 and straps to support the sink from above, while we cut the plywood from underneath.

I couldn’t get a good camera angle from underneath to show you guys how to cut the wood but basically what happens is, once the wood is cut, the sink is literally going to drop.

Therefore, if we keep it supported from up above, then we can safely lower it down without actually creating any damage even worse, falling on some plumbing pipes and causing a really big issue, so you want to get a really good game plan together What you see here is We are cutting out the corian for the new sink.

You want to make sure and read those instructions Read the cutout dimensions based on the model sink that you have It’s very important that you do this.

It’s a very tight tolerance and we are cutting to the 1/16″ of an inch all the way around once the cutout has been made go ahead and check for fit make sure everything looks good then all we need to do is install the plumbing i highly suggest hiring a licensed plumber to do this You do not want to mess around with plumbing because it could cause an enormous amount of damage to your house with any leaks.

Once everything has been connected, simply turn on the water and check for leaks.

You also want to run the dishwasher and check for leaks as well :).
