Dumb Plumbing Question - adding spigot near sink in garage

I'm lucky to already have a sink in my garage with hot/cold water in a drop in utility style sink cut into a counter/cabinet.

I'd like to add a hose real mounted on the side of the cabinet so I have easy access to wash cars and things from that garage water source. Ideally I'd love to be able to mix hot/cold water when filling car wash buckets.

What's the easiest way to add this second connection while also giving myself the ability to adjust hot/cold without having to go under the sink every time?

I'd like to mount a wall mount side reel like this on the side of the cabinet next to the sink, and I'd rather not have to hook/unhook the source to the sink tap. (leave hose hooked up and still use the sink whenever).

I have a shop sink in my garage and I just thread the hose right onto the spout. Do you need a second source or can you get away with a faucet change?

I could swap out the faucet for one like that, I guess i was looking for a "just leave it connected" option. (first world problem I know).

Basically leave the hose connected and still be able to use my sink at the same time.

Run a new hot and cold line to the reel, valve on each line, T outputs together, then screw your hose on. I think it would be be ok code wise so long as you use a check valve before each mixing valve(good idea anyways).

I agree with woody, the sink connector. Hoses on a reel, charged, rupture. And usually at the worse time. You could rig up another faux spigot for it, using two valves to control the mix. But I don't think it would be worthwhile.

Well yeah I wouldn't leave it pressurized.

Use the faucet as mentioned above then put a Y fitting on it so you can keep the hose hooked up but still have access to the faucet if that's what you'd really like to do.

Do it the right way. Get below the sink and add in some Tees and find a hot and cold hose bibb at a store. Make sure you get one with a vacuum breaker built in or get one that goes between the threaded end of the hose bibb and the hose.
