    Holy Cow this is the most GORGEOUS sink… I really wanted a “real” vintage sink and found one (they are super heavy) but the re-finisher told me that kitchen sinks just don’t hold up when re-finished, I was heart broken, I wanted a early century kitchen sink. NBI saved my dream!!! I will admit I was leary and was even afraid to open the box when the sink arrived ( shipping was super fast and the sink was well protected for shipping ). I unpacked my sink today it is ALL I could hope for and more, a lot thicker material then I was afraid it would be ( there is NOTHING flimsy about this sink ). This sink is heavy duty and BEAUTIFUL!!! I LOVE my new sink…. THANK YOU NBI for making my dream kitchen possible!

    I really, really, really like my sink. After months of waiting, I finally found a contractor who would renovate this kitchen in what was apparently a very uncommon style. The sink was installed today by a plumber who had never seen a sink like this one. It must have been easy enough for him, because it looks great. Was TOTALLY blown away with the Kingston Wall-Mount Faucet in bronze, handling like it was a precious gem. The counter top guys were so impressed, they wanted to use my ideas to suggest to other people. Granted I do live in Alabama, so these NBI styles may not have yet been discovered. I LOVE NBI. Maybe one day they’ll make some ultra cool bathtubs!

    This sink left me speechless! It is a work of art and I LOVE it! Our kitchen is still a work in progress, but I wanted to wait until we painted the cabinets to send you a picture, because it would be a drastic change. There isn’t a thing I don’t love about it. The hardware matches excellently. Thank you so much! Your professionalism and helpfulness made this process even easier. I will forever be grateful I found NBI!

    Love this sink! Put it in our remodeled 1930’s kitchen. Had wanted a cast iron sink, but we are aging do it yourselvers and knew we could never deal with the weight of the sink. This solved our problem. I painted the outside of the sink a dark turquoise with chalk paint, to disguise the fiberglass look, then mounted it on a pipe stand. It looks wonderful! So proud of it and so far super easy to keep clean. Bought an American Standard retro style faucet to go with it. It is very much in keeping with the age of the house but with a cool updated twist. Hope it lasts for years and years!

    My sink arrived very quickly and in great condition. It truly is gorgeous! The material seems quite durable and it’s nice and light (in comparison to the cast iron models). The only thing I would caution prospective buyers is to make sure your plumbing can be set up to accommodate the faucet. That has been our only challenge installing the sink as we live in a cold climate and the sink is on an exterior wall. Would definitely recommend NBI.

    Could not find an original cast iron sink in good enough condition for my new kitchen. Thankfully found NBI sinks! Beautiful reproduction, and only 45 pounds. My sink has been installed for a year and has been a great addition. I am an Interior Designer and would recommend this product to any of my clients who wants a ‘vintage’ sink in their space. Clean up is easy, but after a year small scratches & dark marks appeared from metal pots. Easy remedy is Novus Polish sold on this site. With a little elbow grease scratches are removed and sink looks like it did a year ago when installed.

    Love, love, love my new kitchen sink; THIS is a farmhouse sink! I’m grateful that NBI was able to reproduce the early century models. Since I have a window over my sink, I was concerned about the backsplash height. After speaking to a staff member, it was a not a problem. Everyone loves this sink. I also bought the Kingston faucet/spray to complement the sink and it looks amazing. Shipping & packaging was great. NBI is an excellent company to work with…thank you so much!!

    My sink is beautiful in my newly remodeled kitchen! Everyone who sees it says they have never seen a sink like this, with the built-in backsplash – including my contractors! It gives the kitchen in my 1910 home the retro look it needed. I could not be happier with the look and finish. The light weight of the sink made it so easy to install too. So glad I selected this one instead of one with an apron which is so popular now.

    I wish we could upload photos so you could see how beautiful it looks installed. All previous reviews about this sink remain true. I want to add that our pipes were not already at the height of the faucets of the sink prior to purchase and we thought we would have to relocate them. To our pleasant surprise, we did not have to cut into our wall to run new pipes. The backsplash allows for pipes/tubes to be fed behind it. We’ve only had it for a few months so we will see how well it holds up to scratches. All is good for now.

    This sink is every bit of beautiful and adds just the right amount of charm to our kitchen. I love it and was so shocked how big it is in real life. I kept breaking out the measuring tape prior to my purchase to make sure it was going to be big enough and it is absolutely perfect. It looks like cast iron with out the weight of cast iron! I couldn’t be happier with this purchase and I am so thankful I found this site!!!
