That is where I was going to suggest you put it. I'd leave a space of about 12" from the wall to the left of the sink. I had a 24"X24" composite laundry deep sink in the garage in our last house and found the size ideal, but I didn't like the inevitable staining of the composite. For the faucet I used a gooseneck type and also put in a spray nozzle. I also put on an aerator that had male hose threads on it.
I'm considering putting one of these in the detached garage along with a 2 gallon water heater which will be sufficient for my needs.
I need to get quotes for running a cold water supply and waste line from the house to the garage.
Sorry I missed your post earlier. I like the sink you linked, but not the faucet. I wonder if a more heavy duty faucet could be an option for that sink. In my old place, I had an 18x18 stainless sink with a sideboard, and a bridge faucet with a regular spout and a spray hose. I really liked that setup, though I'm not sure I need the sideboard. So maybe something like
this ?
Also take a look at the bridge-style faucet shown in post #8. I've found this to be much more convenient than one mounted on the back of the sink itself. They also often tend to be a more industrial design, so hanging a garden hose off it doesn't seem to stress them much.
Agreed, that's a good type of faucet to have, I'll look for that.
Another thought. Have you considered putting in one 20' door in place of the two 10' doors on the left. In my experience that gives greater flexibility for the use of that side of the garage.
I hear you, it's a good suggestion. Unfortunately we're past that point, it would require re-engineering the design, and also changing the doors, which have just been ordered. So I'll have to make peace with what I have for the structure

Plumb the garage for a toilet also if you can. My plumber puts the lie in put seals it. It was about a half inch below the concrete. They poured concrete over it for removal later if desired. It is easy to break the half inch of concrete out if and when. I also put several two inch receiver size square tubing in floor. It allows me stick a post in with vise or grinder on it. i also buried pvc to an area so I could have air or electric line if desired.
I originally wanted to have a toilet, but that would have required us to upgrade our entire sewer line, and after thinking about it a bit, I decided to not do that. As it is, it took us 8 months to get this permit - changing the sewer would have created all sorts of additional hoops I didn't feel like jumping through.
How would the things work if you moved the man door 16' toward the sink? That way you could maneuver long things in and out the man door without being near the cars and be able to walk in from the outside, wash, and leave with out the trying to walk between the car and the wall. Also think about the 'stuff' that is going to be leaned up against the wall that will then block that aisle.. The wife or junior wants to wash something and scratches the car as they walk along side it to get to the sink.
Thoughts that cross my mind because I've suffered these problems. Last house the sink was outside the shop. This shop I now have I also put in a 48" man door and have thanked myself many times for doing so.
On second edit, I also hate the 2' from the garage door to the side wall. My one big regret in my building. It really kills any options of storage or opening the car door and moving around it. If you really don't have a need to park 3 rigs in the garage and intend to use it more for a workshop consider 2 OH doors and more room on the sides.

no neat sig line
Good thoughts Larry - unfortunately what's not clear from my drawings is that there's an elevation change in the property along that left wall, so that the soil is about 3 feet higher at the back end than at the front (if that makes sense). So the man door where it is now is at the level of the slab, but if I put it further back, I would have had to create an additional retaining wall that's three feet high, to have that door at slab level.
