Chris may have one for me. If that doesn't work out, I'll definitely take some pics under the sink.
The main issue though, is that my carriage house (complete with barn doors) was converted like 50-60 years ago. To put things in perspective, I have a vintage gas stove...that was clearly installed before the walls were completed because there's no way it could've fit otherwise, lol. Due to the lax (or lack of) inspections back then, there is no insulation in that room. The copper pipes under the sink, to prevent from freezing, are basically wrapped in insulation with a sleeve of PVC over them. There MAY be a couple places the copper is exposed, but I'll have to check again. I just remember taking a glance then having a "f--k no" moment when considering tapping that line.
