The sink's glossy finish and simple rectangular shape are admired for their aesthetic appeal. Despite initial concerns about its simplicity, users find it to be a durable and reliable choice, with no issues of rust or scuff marks even after years of use. The sink's surface seems to resist stains, requiring minimal cleaning to maintain its shine. Although some consider the price on the higher side for a single bowl stainless steel sink, the long-term satisfaction and quality make it a worthwhile investment. Overall, the Blanco Supra 340-U 512446 is a decorative and practical addition to any kitchen.

When I was shown this sink in the store, I grimaced because it looked too simple. But my husband insisted on this model. He consulted with installation specialists, and they strongly advised choosing something from Blanco. The main argument was that their sinks are high-quality, even, and they don't present difficulties during installation.

And then I was delighted, undercounter installation looks very advantageous after all. In fact, it's also very convenient. From a maintenance perspective, there are no problems with the sink at all. Using any cleaning agent in the form of "milk," the sink starts to shine. But I clean it quite rarely. It seems to me that the sink is coated with something, so stains practically don't appear on it.
"decoration for any kitchen, easy maintenance"

Installs under the countertop and looks great! Very modern and suitable for any kitchen. No dancing with a tambourine or special equipment, easy to clean. There was a funny situation - suddenly they found a rust stain. They had already sworn at it, were about to return it under the warranty (it was for five years), and then they started cleaning it and it turned out that it was the husband who had soaked the grill grate and it had left a stain. The stain came off naturally) And the sink itself has served perfectly for three years and there are no signs of scuff marks, much less rust. The metal is gorgeous.

Very pleased that the sink looks like new after five years. Glad I didn't skimp. I would have saved a maximum of five thousand, and then looked at a worn-out sink for another 10 years.
I've had the Blanco Supra for about 5 years now. Back then, under-counter sinks were quite rare and it was the height of fashion)) Plus, Supra has a very beautiful polish and a simple shape. All my friends were amazed, and I was too :) I did have doubts back then that the countertop would deform. But thanks to proper sealing, there's been no issue.
For a stainless steel sink with a single bowl, the price is, of course, not cheap. But after seeing it, nothing else caught my eye.
