When choosing which sink to buy the deciding factors are usually size and aesthetic appearance. In terms of functionality, there is not a great deal of difference between them. When I came to plumb in a Langudden Inset Sink from Ikea for a customer in Clifton Bristol , it stood out as an especially good sink compared to the others.
The most notable feature is the sound-absorbing material attached to the underside. It is not at all uncommon to find one panel of such material on any standard sink. The Langudden, however, has one of these panels attached to every single side as well as underneath. As one might expect, this deadens the clink of pans and vibration of water much better than the standard sink can. It also makes for a much more solid-feeling basin.
From a plumbing point of view, I modified the Langudden to enable it to fit to a standard waste as the Ikea wastes are not a good long term solution . The overflow that the sink comes with has a proprietary, oval-shaped connection. In order to install it onto a standard waste and round plastic over flow pipe , I simply heated the over flow pipe with a paint stripper gun to make it supple. This allowed me to push it onto an oval connection on the overflow,
There is not much more to say bout the Langudden. Other than it is a very good sink for the price.
