Thank God this is so easy. I was just chilling, watching Netflix and doing dishes, and THE SINK FELL OUT BRO. didn't even know that was an option.

I'm glad I came across this video! Always wanted to replaced my sink but thought it was too hard to replace and didn't wanted to pay top dollars to have some one do it.
Everything went smoothly on my installation and lowe's had everything I needed I would do it again ☺️ I'm So Happy With My new Sink thank you guys and Lowe's!

I think the stainless steel sink looks pretty good.

DON'T EVER INSTALL A BLACK SINK, YOU WILL SEE ALL THE DIRT & GRIME ALL THE TIME NO MATTER HOW MUCH YOU CLEAN IT. Get A Tan or Grey color Granite compositions sink to avoid ugliness if you cook!

Thank you for this video! We thought it was much more complicated due to our countertops and realized we can do this after watching! Also, the links are great!

Oh, I really needed a video like this. My sink is attached like this, and I really wanted to change it. But I didn't know how to do it at all. But now I know it thanks to you guys. Thank you so much

Thank you! I have always thought I'll have to remove the counter top in order to replace an undermount sink. Turns out I don't have to!

I laughed when Ashlee wanted to change a working sink just because of the colour, but I can't lie the new sink looks way better! Good call!

Thanks! installing a 12" counter with a 4" L corner and did not want to have to flip it over first to install the sink. Was looking for some sort of trick to mount the sink after installation and this will work perfect. Great thinking.

To get the excess silicone that squeezed out... rather than a damp cloth ... use a spray bottle with water and a small bit of dish liquid, spray around the top of the sink and the granite, then with a clean piece of cardboard simply scrape off the silicone in one pass... the soapy water will keep the silicone from sticking to the granite and the sink....

But u didn’t even explain the install process . You said yours was apoxy but u skipped right over what that means . That right there would have a guy stuck in his tracks . Please elaborate

Great video. Thank you for making this job a lot easier. You saved me a ton of time.

Been watching these videos trying to figure out how to do this as my clamp won't fit through the drain. I had NO IDEA the end of my clamp comes off.... awesome video.

I am so embarrassed to admit that I thought an undermount sink went directly under the countertop so that you had to remove it to replace it. My mind is blown that it's just attached underneath!

Where’s all the existing plumbing in the cabinet that probably made the job nearly impossible? Looks like this was done on a Lowes Kitchen Display. Nothing’s that easy.

sink is only showing one outlet, but under the sink you are showing two connections 2:30 dont understand!!

How is the black sink going for you? Regret the day I chose a black slate sink and black faucet! Can’t wait to get rid of them and go back to stainless or even white. Black shows EVERYTHING.

Is it possible to remove the sink through the top (the hole in the granite) by rotating onto its side? My cabinets have a center pillar (between the two doors) that prevents removing through the bottom as in this video

[wbigelis]

the most important part, the clips, is just glossed over.

I liked the stainless steel sink better. The black one looks like it belongs in garage or machine shop.
