Questions & Answers

Does this sink have a Center-rear drain placement or is it True-center (center from side to side and back to front)? The photos all show it is truly in the center as I need it to be, the description says it is Center-rear. So which is it please?

    use thus far
    I had installed last Friday and have had no problems thus far. I purchased the 3 hole but only used 2 hole for a single faucet and soap dispenser which was now on the left side vs right. I had to purchase a faucet hole cover for the third. All our appliances are black w/ stainless steel trim. The cover I purchased was black and it gave added beauty w/ the stainless steel sink and matching all other applicances.

    Very poor mounting design, fair quality sink.
    18 gauge steel is not thick enough for a quality sink, 16 gauge would be perfect. But the biggest disappointment is the engineering of the mounting clips. The company should be embarrassed in the design of this mounting system as it lacks all ergonomics and human factor engineering! Instead of a hex head/Phillips head combination screw, the mounting screw is a straight slot head with a groove so narrow that only a jeweler's screwdriver can fit in it. I had to grind down one of my long handle screwdrivers to fit in the slot. And then to attach 8 clips to the sink took about an hour due to the screwdriver slipping out of the groove. Worst engineering I have ever encountered!!!

    Surprisingly Obsessed with This Sink – A Must-Have Upgrade!
    I didn’t think I could get this excited about a kitchen sink, but here we are. I installed the Fusion 33” Top Mount Workstation Sink about a week ago and it completely transformed my kitchen. The top mount drop-in install was incredibly smooth—perfect for a quick upgrade without hiring anyone. Within an hour, my kitchen had a sleek, modern centerpiece. I also love how deep the single bowl is—it easily fits big pots and pans without splashing water everywhere.. Bonus points for the accessories, everything is thoughtfully designed and actually useful—not just filler. It’s rare to find something that nails both the form and function this well, especially at this price point. Highly recommend—it’s made my everyday kitchen routine genuinely more enjoyable.
