Dual Tier and Tri-level Workstation Sinks - the only and the original. 3 US patents.

Many years ago I invented the first dual tier sink in the industry and was awarded 3 U.S. Patents. I called that sink Evolution™. It had 2 interior steps and is far superior to other dual tier sinks. June of 2020 we introduced a new, design called Paragon . The Paragon™ design is shown and described below. "It's the sink that can do it all, for all occasions, including food prep, clean up and serving while adding extra counter-height work space." -Forbes Magazine

From the company that introduced the very first workstation sinks to the industry, we introduce the Tri-level Paragon™ Workstation Custom Sink. We are truly purveyors of time.

Our Paragon, design is the most advanced dual tier, tri-level workstation sink in the world. Work on three levels. Half sheet pans can fit on top tier and on the bottom in the same orientation! Try that in any other sink on the market. Save up to a week every year compared to traditional sinks.
It is now possible to have two tiers without losing any bowl space below the tiers. No other dual tier sink is remotely as large. Our new design adds a whopping 92 additional square inches of usable space in a 48" sink. Just to give you perspective, that is equivalent to a full size sheet of paper (8 1/2" by 11") The NexGen™ and Paragon™ designs are protected under U.S. Copyright and trademark laws and may not be reproduced!


Copper, Stainless, Bronze or Brass. Paragon™ is also available as a farmhouse sink, undermount or a drop in style.
Wouldn't it be nice to set a half sheet pan on your sink ledge? That options is now available on all workstation sinks.

I have put my 40 years of design experience into the formulation of my Evolution™ and Paragon™ Dual Tier Designs. I considered ergonomics, food preparation, clean up, serving and aesthetics. I truly believed this is was consummate kitchen sink - especially in an island setting. Well, my amazing assistant, Jessica, came to work one morning with a new idea that is a blend of my Evolution™ design and my NexGen™ designs. The architecture of the sink, is clearly perfection in design utility. The Evolution Sink (and now the Paragon™ Sink) is a sink for all occasions: Food prep, clean up, serving, and additional counter space. Today, the kitchen sink has finally evolved to attend to our current lifestyles. Our fast paced lifestyle deserves a kitchen sink that can do it all, quickly and efficiently. Do you have a small kitchen and think this sink is too large? Think again... This sink adds valuable counter height work space in your kitchen. There is no loss of space. You actually gain usable work space! The Paragon™ workstation sink can be the crown jewel in your home.

Each sink is custom designed to suit the user based on many things including handedness, food prep style, entertainment style and height.

The precision required for our custom sinks significant. Compare our interior corners to the others. Ask to see a close up photo. You will be surprised! From forming, to welding to finishing. This is a complicated design. Everything has to fit perfectly, and it will! Paragon™ is a time-consuming sink to build and finish, however the end result is worth it. If you make the selection for the 18" width to hold half sheet pans, the investment amount covers not only the extra width, but the custom sized accessory cost for whichever accessories you select.

Three patents have been granted on my original dual tier design, Evolution™. The Rachiele® "Evolution™ Sink" and the Paragon™ sinks are now available. There is a fairly long waiting period, so order early. If you love to cook and entertain (like I do) you will love this sink!

Don't be misled by other sinks offering similar designs. Ours is the only sink on the market with two interior ledges. There really is no comparison with the Galley and my Evolution or Paragon™ sink. The Galley sink (and others) are virtually the same design as my original single tiered Signature Series Sink (a design that preceded the Galley Sink). They simply made the flanges wider and exposed a portion of the flange as their top tier. I have never offered that option with my sinks because there is no way to keep water from sitting on that ledge unless you wipe the ledges down after every use. My 48" Paragon™ sink offers an additional 92 square inches of usable bowl space compared to the Galley Sink.

I do have to give the Galley Sink folks kudos though. Their brilliant presentations are stunning and their videos and photos are very nice. I don't have an advertising budget so don't expect to be dazzled. (Yes, I am a bit jealous) They also seem to have a wonderful reputation and a loyal following - always a good thing to hear.

My Evolution™ sink has two interior tiers. Our new Paragon™ ™ design has three levels of use. These are the main reasons that distinguishes our designs from all other legally produced sinks on the market. One of my three patents shown below.

Thoughtful design is key. All too often sink designers fail the ergonomics or functional test. I see sinks with steps that are too high or too low, I see cool looking accessories that make no sense in real life use. Sinks should be designed for function, not photo shoots. Every sink at Rachiele is custom designed around the family that will use the sink. I often suggest fewer accessories than are originally discussed, as they may look good in a photo, but perhaps are not appropriate for the use of that particular family. My goal is to offer the best quality and ergonomically designed sink on the market. Our lack of a need to have advertised since 2008 speaks to the workmanship of our team and the quality designs we put forth.

double ledge copper farmhouse sink Hi Dino, This morning I'm cooking for a dinner party this evening, and I was just thinking how easy it all is with our wonderful Rachiele copper sink, and thought you'd like a snapshot. As you can see, it's messy - I've just made soup, oatcakes and pastry, picked rhubarb for a rhubarb custard tart, and the peonies just came out at long last - but there's room for everything. Anyway, just wanted to let you know how much we dearly love our clever Dino sink. Thank you!!! Catriona

Precision production

Evolution and Paragon™ sinks are individually handcrafted using precision tools. They are not mass produced. In fact, every sink design is customized to the user(s). The non drain side is shallower than the drain side; plus all portions of the sink are sloped to the drain. This guarantees proper evacuation of water (a common problem found with other large sinks). Every sink is tested for proper water evacuation before finishing. Each sink is signed by all metal workers and by Dino. Evolution has virtually been replaced by our new Paragon™ design.
