Kitchen sinks usually last a while and therefore do not have to be replaced very often but there comes a time when it just has to be done. It can become costly to replace or have a new sink installed but if you have the right tools you can install it yourself. If you are leaning toward installing a kitchen sink by yourself here is what you will need to install a stainless steel American Standard kitchen sink(s):
A tape measure
1 1/2" hole saw for the faucet holes
Pipe wrench
3/8" hex or nut driver for the sink bolts, or a thin screwdriver – either Slot head, Red Robertson or a Phillip
Flashlight
Keyhole or saber saw
Drill with a 3/8" or larger bit
Clear silicone putty if this is a remodeling job
Pencil
After you have gathered these tools you can begin the installation process.
Step 1: Prepare the counter top – you need to make sure the counter is clear of obstructions such as cupboard partitions, braces or pipes. Also, check the clearances above and below the counter. The counter top thickness should not be more than 1 ½ thick at the sink rim.
If a template was supplied position it flat on the countertop. It should align with the plumbing connections but do not draw around the tabs. Mark the opening and faucets holes on the countertop. If you ware installing a ledgeback sink, trace the faucet holes on the counter top and then drill a hole to start cutout, and carefully cut with a jigsaw along the inside edge of the cutout line, and then use a hole saw to cut out the necessary faucet holes.
Step 2: Prepare the sink – start by removing all the paper tape on the rim seal and protective plastic cover from the sink. You will then put the foam faucet gasket over the faucet holes. Use a bit of tape to hold the gasket in place while you install the sink.
Step 3: Prepare the strainer assembly – using the illustration provided, install the strainer assembly. Locate the strainer housing and hand tighten the tailpiece. 
Step 4: Install sink fasteners – turn the sink right-side up and place the notched end of the bolt into the keyhole slot in the sink bracket. You will use one bolt per double bracket. Then turn the claw to rest against the side of the sink. This all must be done BEFORE dropping the sink in the prepared hole.
Step 5: Install the sink – you are now ready to begin installing the sink. You want to carefully lower the sink into the countertop so the bolts enter without interference. The claws should be turned 90 degrees so they grip the underside of the countertop. Gradually tighten the clamps similar to that shown in the illustration. DO NOT over tighten the claws – they should be tightened just enough so that the sink is flush with the countertop.
Your sink should be properly installed. Read all instructions before installing and check back through to make sure it is installed correctly.
