Outdoor sink station for gardening, fish cleaning and similar?

Question

When working in my backyard which has a small vegetable garden and a few fruit trees and some ornamental plants, I often need to repeatedly wash my hands and tools. Occasionally, I will have fish, shellfish, produce and similar items that are ideally washed outside because of soil and odor and pieces that I'd like to gather and throw out immediately without storing in my indoor trash cans.
I'm thinking about installing a permanent outdoor sink or similar for that purpose. My location has rainy falls, winters, and springs, dry summers, occasionally snowy winter months. I'm not sure what types of product or structure I should look into. Mainly I'm concerned that a wrong type will damage my house in some unexpected way, or will not last longer than a few years. Any suggestions or recommendations?

Edit: I do already have a ground level cement sink which is properly plumbed. It's about a foot from the base of the house and the water goes under the sink and I think eventually into the sewage. It looks ideal to have a small size pet dog to wash feet in. So I'm imagining the new sink station which is to be used when standing can piggyback on this existing sink.

The sink is on the ground. The shorter bright green tube is connected to a water spout whose other end is under my kitchen sink.

Fairly common to keep such things entirely detached from the house and even portable, which solves damaging your house. If cold only works, then you can set it up to have a garden hose supply, and drain onto the ground under/behind it. Park it in the garden near your most water-loving plants. Roll up the hose for winter, or move the whole thing into storage for winter.

You could get a fully stainless steel commercial sink to have nothing that would rot or rust, most folks I've seen doing this just use a wooden frame and a stainless steel kitchen sink.

Edit: Given your ground level drain dray, you could just drain (no trap on the taller sink) directly into that drain tray if situating the taller sink over or near it - but since one of your reasons for the outside sink is "washing things with soil on them" you risk plugging that drain with mud - which is one reason why the typical gardener's garden sink (used for washing soil off harvested vegetables and tools in a more convenient manner than spraying them with a hose) dumps onto the ground, not into plumbing it can clog.

I had a stainless steel sink work a 3’ wide deck to the right.

I built a simple 2x4 frame and anchored it to the slab,

as an avid scuba diver I regularly clean fish and crab, even a few spiny lobsters and shrimp,

I only plumbed cold water to mine using pex some 20 years ago, it has frozen several times but has not yet broke,

I used some hardy siding panel scraps to enclose it,

my drain is directly into a 2 gallon bucket full of small holes and the water waters the lawn. This has worked fine for me for many years.

I did purchase a large nylon square to put on the stainless deck as the stainless was two slippery to filet the fish ( don’t pay extra for the side deck would be my advice).

There were a few times I had wished I had hot water so the one I have at my current home is still plumbed with only cold and a small electric on demand water heater. That the girls use to wash horse brushes I have only needed cold for fish and crab.
