We find sliver sinks to be practical and stylish.
A little-noticed addition to the “smart kitchen” is a novel range of narrow, sluice-like sinks. Most merely 8-inches wide, they are shaped like troughs — hence the name — and come in a variety of lengths ranging from 5-feet to just under the standard 24-inch counter depth. After seeing the extensive range made by Kohler in their Undertone line, I’m beginning to feel this shape is more practical and space-efficient than than round, square or even rectangular prep sinks seen in most kitchens.
These sinks are meant to be under-mounted and their length basically determines whether they are installed horizontally or vertically in a cabinet. Among the most intriguing is Kohler’s high-tech slanted Crevasse, designed to fit a 36” sink base. This is an automated sink with automatic rinse at the push of a button and a garbage disposal. The water and disposer action is integral — no faucet required. It is shown installed at the back of the counter — directly behind the prep space. We are super intrigued by this and surprised not to have seen it in more high-end homes.
Far less expensive, but equally intriguing, are the plain under-mounted trough sinks. The longer versions can be placed horizontally as prep sinks, just like the Crevasse. Most useful here may be the 22-inch long unit which comes with draining racks. 
This can be installed side-by-side with any main sink (shown with the Verve drop-in) as a secondary (or tertiary) bowl — with or without a disposal.
Then there are integrated trough sinks in stainless steel counters. This one was intelligently placed next to a cooktop particularly with a potfiller (Rohl Swing Arm) installed.
Alternately, a single cold-water pillar tap could be placed in the wall over a trough sink in the way it was done a century ago in Claude Monet’s amazing Giverny kitchen.
I would love to have a cold water tap… very “cool” …
What a wonderful idea…would love a sliver sink!!
Pretty clean look!…Christine
The 22 inch trough is EXACTLY what I want for my Island . Where can I find one ? Thx for the help
Monica, the sinks are from Kohler — details are on their website.
