Easy DIY Guide: 12-Step Countertop Sink Installation
Step 1 - Prepare the Area
Start by clearing the countertop of any items and place a bucket or towel underneath the existing sink plumbing to catch any water when you disconnect it. Turn off the water supply valves underneath the sink.
Step 2 - Remove the Old Sink
Use your adjustable wrench to disconnect the water supply lines from the old sink's faucet. Ensure the bucket or towel is underneath to catch any residual water. Next, disconnect the drain pipes by loosening the slip nuts with the pipe wrench. Remove any mounting hardware or clips securing the sink to the countertop.
Step 3 - Clean the Area
Once the old sink is detached, make sure to thoroughly clean and pitch dry the countertop before proceeding. Remove any old caulk or adhesive before you continue with the new sink installation.
Step 4 - Measure and Mark
Measurement and marking are crucial stages for the sink installation. Measure the dimensions of your new countertop sink accurately and mark the exact placement on the countertop area. Ensure that the sink will fit comfortably and that the faucet holes align correctly.
Step 5 - Install the Faucet
The new sink will require drilling work if it doesn't have pre-drilled faucet holes. Safeguard yourself before operating the hole saw or a spade bit appropriate for the faucet size. Follow the manufacturer's instructions clearly while faucet installation, securing it properly to the sink or countertop.
Step 6 - Assemble the Drain
Go through the manufacturer’s instructions before assembling the drain kit. Wrap the threads of the drain pipe with the plumber's tape to ensure a watertight seal. Insert the drain pipe into the sink's drain hole, securing it with the provided gasket and nut from underneath the sink. Tighten the nut with a wrench to create a snug fit.

Step 8 - Connect the Drain Pipe
Start with connecting the drain pipe to the P-trap and secure it with the slip nuts. Ensure all connections are tight to prevent leaks. Get your hands on the hacksaw, if only necessary, to trim the tailpiece of the drain pipe and adjust it to the correct length.
Step 9 - Attach Water Supply Lines
The water supply lines are to be attached to the faucet and while following the process, shut off valves under the sink as a precaution. Secure the connections using an adjustable wrench, exercising caution to avoid over-tightening, which could potentially harm the threads.
Step 10 - Test for Leaks
Turn on the water supply valves and check for any leaks around the faucet and drain connections. Tighten any loose connections as needed.
Step 11 - Apply a Bead of Silicone Caulk
Take the silicone caulk and apply a single bead around the edge of the sink. The bead must be placed right where it meets the countertop. Smooth the caulk with your finger for a clean finish and to prevent water from seeping underneath the sink.
