We had a potting shed at our old house but we're still in the throes of constructing one here. It wasn't really planned as a potting shed, in fact it was an outdoor kitchen for a failed business venture - but that's another story.

This place, that we'll call the potting shed, had a large stainless steel bench at one end with a sink and running water. The sink sat at the far end of this bench and allowed me to throw all my pots into a bleaching solution and then once cleaned they could drain on the bench. Then I would stack the pots into their respective sizes ready for my next potting spree.

The beauty of this shed was that it kept it all indoors and out of the weather. So no matter whether it decided to bucket down large hailstones, I could venture into my potting shed and start propagating some plants or pot up some seedlings. I was only limited by my imagination - and the number of pots I had.
