    Overview

    This undermount sink will add a touch of refinement to any kitchen. Built from 304-grade stainless steel and finished with an 18/10 brushed satin, it strikes a neat balance between style and functionality.

    Its generous 40L capacity gives you enough room for your larger pots and pans. Radius corners make cleaning a breeze, preventing the formation of dirt traps.

    With the included colander and cutting board, your sink will transcend a wash station and become a meal prep hub. There is also a drainer tray for helping your freshly washed dishes dry off.

    Great purchase!
    I love this sink, more so because of the addiitional components that come with it and fit so nicely! My preference was not for a square based sink but I still do love this one.

    Happy with the purchase
    I love the width and depth. Having gone down to one larger sink instead of two small, I am happy with this.
