Picture of Garden Workbench with Grey Water Sink
A great 2-in-1 project!  I needed a workbench in the backyard for quick small projects.  I also wanted to start rinsing our garden harvest outside.  The simple faucet addition to this bench helps keep dirt out of the kitchen sink AND reclaim the grey water for irrigation. 

This is a very quick and simple solution, and I mainly used materials I already had on hand.  However, I think it provides a great baseline for you to create your customized version of a garden workbench & sink.

Step 1: Materials and Tools

Picture of Materials and Tools
Tools: saw, power drill, square, level, wrenches

plywood (mine is 28" x 36" and Made in Texas)
2x4's (mine are 4 x 28", 4 x 33", 4 x 38" and Made in Texas) 
@ 30 x  3.5" deck screws
@ 30 x 1.5 deck screws
1 x bucket
1 x faucet
1 x 'Y' split hose adapter
1 x 1/2" hose coupling (part no.: Watts  A-810)
1 x 3/4" / 1/2" Hose adapter (part no. Watts A-677)
1 x garden hose (length depends on your environment)
thread seal tape

Step 2: Frames

Picture of Frames
Construct 2 frames using the 28" and the 33" 2x4's and the 3.5" deck screws.  Make sure they are square - or at least square-ish. 

If you cut different sizes (or even to double check the layout) I recommend placing the 2 x 4's on top of the cut plywood to ensure that you have the boards lined correctly.  On my bench, the 28" board is on the sides and the 33" are on the inside of the 28".

Step 3: Legs

Using one of the frames created in step 2, add a 38" 2 x 4 to each corner, making them as square and level as you can - but without stressing too much if it's not exact.   My bench in going on decomposed granite, so I know it will require some leveling once I'm finished.

NOTE - plywood shown in picture is not yet attached, only being used as a guide here.

Awesome Instructable. Saved me a lot of time and effort by using garden hose plumbing! Used the same idea, but the garden I work in had a spare sink tub laying around and a workbench already made, so I put the two together. Cut a hole in the workbench and let the tub rest in it. Used a cheapie Glacier Bay faucet from Home Depot, but realized that the faucet was way too short for the sink size so I got a somewhat flexible sprayer attachment. Same deal with the Homer bucket to catch the water. It's a great little "food prep" sink and other garden managers are very happy with it!

Nice faucet for this purpose - where'd you get it?

If your soil is as rocky as mine you might enjoy having a piece of expanded metal over a hole for screening out rocks. Also works for screening out root mass when recylcing dirt from dead flower pots.
