I'm thinking about making a small sink for my DIY lab. Since there is no running water or drain, I was thinking about something similar to a camping sink like this one.

I'd make some modifications (e.g. using a ceramic basin rather than a plastic one, since it will be fixed).

Now, for the water reservoir any container is fine, but I have doubts about the material of the drain plumbing and container. I'd usually use it to wash the hands (so only water + soap), but I'd also occasionally use it to wash tools and items, which can include also chemicals (e.g. ferric chloride to etch PCBs).

What material is usually used in these cases, and what are its limitations? (e.g. this plastic is ok for acids but when used with gasoline breaks).

For instance I found containers and pipes in PE or PVC or PP; is any of these materials suitable?

    DIY lab. Since there is no running water or drain - I'm guessing this is in a shed or detached garage.

  • @Ecnerwal the "gasoline" part was because I know that some plastic containers are not suitable for gasoline storage (because gasoline can "melt" them). That was just an example to show the kind of reply I'd like to receive: suggested material and associated limitations. I want to assure you, though, that no gasoline will be put in that storage container; I used that as an example because it is the first example of "not suitable plastic" that came to my mind

#1- Plastic Buckets are cheap. Use one 'til it is no longer usable, buy three. (My favorite are the Lowe's buckets. I have put all kind of nasty stuff in them.)

I lived for many years with a water jug on a shelf above a double sink with plastic buckets under each bowl (and a camp toilet in the bathroom). The key to remember is LOOK UNDER THE SINK to see how full the buckets are.

A small galvanized trash can would hold more liquid. I am not sure how water tight they are. I have had ones that held water. Maybe a stainless steel one from a restaurant supply house would be a good investment.

A galvanized bucket would be a good choice.

  • Thank you for your answer. I'd avoid metal because of rust and corrosion, so I'd go with plastic. Since not all plastics are made equal, do you think some material has advantages over the others (usually I find around PP, PE or HDPE containers)
