My tables are all built in. They are a U shape. I have tools and saws on the side, and 2 workbenches. I also have a 3 x 3 rolling bench that I roll around in between and use for way more than I ever thought i would. Sometimes it holds planes, sometimes tools. Its all good.

I went with a bench at about 40 inches. I can stand and work, but now with the broken back I find I use a tall stool mostly. Now I wish it was shorter because i can't stand at it for very long. One more month and that might change.

Make it at the height you like the best. Most of my friends like to sit and work in a regular chair. I prefer to stand if i can.
