We placed the dishpan in the sink to the left side and rinsed on the right side. Then we upgraded to apartments or homes with double-sinks and we kept our dishpan. And here are the benefits . . .
You can lift it out completely and move it out of the way onto a counter to use the sink and still let dishes soak.
The sink doesn't get very dirty on the side it sits in.
If you want to hide the sharp, unwashed knives from your young children, you slip them into the sink that the dishpan sits in but right NEXT to the dishpan (obviously not IN it to avoid cutting yourself).
You NEVER have to reach your hand into soupy, orange, left overnight, greasy dishwater to unplug it. You just lift up the dishpan and pour the water out.
And this, dear friends, works for me!
