I have two similarly shaped and sized basins side by side in my laundry room. To say they are inconvenient is an understatement. They are too small to easily wash a tray after use, let alone use for washing prints. Look for something that is at least twice as wide, and shallow - i.e. a real darkroom sink. Eventually, I will replace those two slop sinks (which is what they are called in the US) with something more appropriate. I don't really need running water in the darkroom proper, so I doubt that I'd relocate the fixture.
BTW, you should not need to go to ebay for this sort of thing. Likely you'll find them in your local hardware supply place. Here you can find them very cheaply at Home Depot, or Lowes. The material will give you no problems with darkroom chemistry.
