Planning Before Installation

Good planning makes installation much easier and prevents problems.

Measuring Your Space

First, measure your current sink opening to make sure your new sink will fit. Check the depth too – deeper sinks might hit pipes underneath.

Step-by-Step Installation Guide

Now for the main event. Take your time and follow each step carefully.

Step 1: Remove the Old Sink 

Step 1 Remove the Old Sink

The installation begins by shutting off the water supply and disconnecting the old faucet lines and drain pipes. 

Once the plumbing is loose, the mounting clips that hold the sink to the countertop are undone.

 A putty knife is used to carefully break the adhesive seal around the rim, making sure not to damage the laminate surface. With everything freed, the old sink is lifted out and set aside.

Step 2: Prepare the New Sink and Faucet

Step 2 Prepare the New Sink and Faucet

Next, attention shifts to the new stainless steel sink. The faucet and pull-out sprayer are installed directly onto the sink before dropping it in place, which makes the process much easier. 

The built-in gasket around the sink rim and factory-mounted clips are highlighted as features that save time and prevent leaks. 

The spray hose is connected, the weight is added for smooth retraction, and the faucet is tightened securely.

Step 3: Adjust Plumbing and Dishwasher Connection

Step 3 Adjust Plumbing and Dishwasher Connection

Before the new sink goes in, the plumbing beneath the cabinet is updated. The old standpipe system connected to the dishwasher is removed because it’s outdated and no longer code. 

The unnecessary trap is capped, and the dishwasher drain line is rerouted directly into the garbage disposal’s built-in connection. This ensures a safer, more efficient setup.

Step 4: Install the New Sink and Drain Components

Step 4 Install the New Sink and Drain Components

With preparation complete, the new sink is carefully lowered into the countertop opening and secured with the clips underneath. 

The hot and cold water supply lines are reconnected to the faucet, and plumber’s putty is rolled and pressed around the sink strainers to create a watertight seal. 

The garbage disposal is then locked into place under the left bowl of the sink, tightened against the adapter ring to ensure no leaks.

Step 5: Final Hookups and Testing

Step 5 Final Hookups and Testing

The last step is connecting the drainpipes and dishwasher discharge line. Using gaskets and compression fittings, the installer reconnects the P-trap and makes sure all drain components are aligned properly. 

The dishwasher hose is secured to the disposal with a clamp, and all fittings are tightened.

Finally, the water supply is turned back on, the faucet and sprayer are tested, and the garbage disposal is run to confirm everything works without leaks.
