The solitude of the DR is truly a healing endeavor for me.
You're lucky with the sink. Although my setup has matured into a very decently equipped workspace, a sink is the one main thing I lack.
I have holding trays and jugs of tap & filtered water handy.
The rest of the time it's up 10 steps to a utility room for final wash.
It seems I climb those stairs way more than just for final washes...
