I have my winemaking area in my basement...no sink in the area either. I don't worry about my equipment until just before I need to use it. Then I'll usually use my primary fermenting bucket to put some water and easy clean in. Clean everything I'll need, then dump and make up a solution of K-meta in the same fermenter, again keeping all of my "tools" in it. It's some running back and forth to a sink a ways away, but no sacrifice is too small for the end result. Others on the forum have suggested a tube with one end open to put your paddle, etc. in. Next time I'm going to use a wallpaper tray (new of course) to keep my tools and sanitizing solution in while working. I use the floor drain in my basement to dump into.
