Don't have an option to plumb a sink
Chrome sink (moved) installed on a counter (moved) which is located at the roof (level 3?) of fire depot in Rosewood.
It has a rain barrel one tile behind and above it. I have a wrench.
I've tried to change a ground tile under the sink and counter and rebuild a barrel instead of moving it.
I've also successfuly plumbed two sinks, a washing machine and a bath on the 2nd level.
