Portable sink

I want to make a portable sink for my workshop. Don't want to bother with plumbing, just a clean and waste bucket. There are pic related being sold for an outrageous $2000. Obviously I can diy my own for much less. I'm thinking of buying a 1gpm pump for $70 and a vanity with a sink/faucet kit for $200 and putting it all together. Might even get a small 700W point-of-use water heater to connect a hot water line into and power it with one of my 1400W LiFePO4 power stations.

Anyone else have experience with such a build? Also can anyone think of an easy way to incorporate a urinal into this system, other than just pissing in the sink?

    I feel like the tankless water heater would be more hassle than its worth.
    What are you using it for?
    Just simply washing your hands?

      yeah washing hands. Do you think some chinesium electric faucet like pic related will electrocute me? Also, when it says 2500W, do you think it will run with a 1800W receptacle without tripping a breaker or catching fire?

            That one is probably like 1300, they just think bigger number = better in advertising. If they actually sold one that would trip a standard 15a circuit it would never sell.

          I wouldn't trust that thing not to kill me, not to mention the controls on it aren't like a normal sink (lower flow = scalding temp). You're better off getting an immersion heater that you drop in your intake bucket and just heat the whole thing to a lukewarm temperature. Then you pump that up to a regular faucet with a nice aerator to make your water stretch further

        No. you'll need a 20A breaker and 20A outlet.

    just need a 12v pump from an RV. I'd go 3gpm it's not that much more expensive. you'll need a power source 120v to 12v or you could add a car battery and a small solar panel, the pumps draw very little. add two 6v in series > one 12v.

    adding water you can build in a permanent tank and fill line with a hose connect or a dump in or like your pic just have a siphon hose into a portable water source.

    you might consider a real trap on drain dumping into a sealed cap to prevent smells, but you can probably skip this. not going to want a dedicated (built in) "grey water" tank but just a waste container that is easy to dump. no trap is necessary if you just straight pipe into the open top for easy removal/dumping. again smells are your issue but don't put food or toothpaste in and your soap and water waste should be fairly clean.

    get a cramp pex tool and some crimp connections, they're ace for doing this kind of pluming, add a pex-tube connection for the soft hose going into source. whatever drain pieces to line up sink drain.

    sinks are easy to find on craigslists, sometimes for free. you'll prob need to buy the actual drain.

    then just a cabinet with or without rollers. nothing fancy here.

    I can't think of anything else. should be a two banana project, getting the 12v is probably the "hardest" part.

    Is there a way to connect a water heater/cooler to a faucet? So that the water dispenser taps are always on and water flow is controlled by the faucet handles instead?
