First - nice idea "solid wood" with plastic sink
However the quality is typical of Chinese manufactured items, the "solid wood" is not so solid, the larger sections that are not part of the frame are the cheapest form of lamination - not even plywood - strips of wood sandwiched between two layers of, I believe hardboard. It splits as soon as you screw the sink together.
And on that the screws come with a hex wrench that strips on screwing in the first screw!
Have your tools handy, and plenty of hardware!
(ps their other items are not much better, similar review to follow.....)
