Closet design help

You could use a stick of 1.25" rigid metal conduit and it might not need any extra support.

You'll need a bar sink, minibar refrigerator, tap (or two), counter top and some storage space. I doubt you can fit all that in a 10' closet.

And if it does add a bit of trussing under the conduit. Smooth metal rod welded to the conduit at each end with maybe a 3" bridge in the middle. Picture an upside down clothes hanger without the hook. You want a triangle shape.

NB to OP: Note that is _rigid_ conduit, not EMT. Dad used Sch 40 galvanized for about a 7-8 ft run in the closet here and it was adequate; don't know it would have made another two full feet or not. Sch 60 or 80 would, though.

I've got the same decision coming up with the rebuild of that entry way and rearrangement of the former closet space but haven't yet gotten to the point of actually seeing what it was/is going to take.
