When installing the sink on the countertop, the width should be at least 100 to 150 mm, which is generally the last three, the first seven or the last seven and the first eight rules. However, this is not absolute. It is best to consult your own designer according to the actual situation.
Extended data If the surface length of the water tank exceeds 1200mm, in theory, double water tanks can be used. Because the average kitchen sink is about 800mm in size, there is still 400 to 500mm space for cutting boards to prepare dishes. Double water tanks will enlarge the overall space of the kitchen and make it more convenient and hygienic to clean.
If the sink of the cabinet is below 1200mm, consider using a larger single sink. Generally, about 650 to 700mm is a relatively large single sink.
A large single sink is very practical. Cleaning large items is easy. If you are worried that the big sink consumes too much water or it is inconvenient to clean small things, you can choose a drainage basket or a basin in a basin. Put it on if you need it, and take it off if you don't want to use it.
