How to model a kitchen sink in Blender 2.5

Here we go again with another example of how to create furniture models in Blender, this time the subject of the tutorial is a kitchen sink. The tutorial I found yesterday shows the process of creation a kitchen sink with Blender 2.5, and unfortunately it is in time-lapse format. Even with the accelerated speed, we see how to shape this type of object. There are a few points that could get reworked, like the messy topology on the bottom of the model near the drain. By a moment I thought that the author applied something like a Boolean modifier.

If you don`t know how to get started with the modeling of a kitchen sink in Blender 2.5, this is a good starting point.
