My grout in the bathroom needs to be redone. Will adding a chandelier
make it come out better?

candles will worki better

O.K. I read the post on painting AFTER I suggested using candles. , but, yes, a plunger would be the best

An auger is my vote. Or an armadillo.

I think the auger could work to hang from the ceiling, but darn, cannot for the life of me, figure out where to screw the light bulbs into an armadillo? Maybe this is an electrical question?

Come on man that's a simple one.
One in the butt, one in the mouth and hang him by the tail.
Gee's lol.
The only hard part is getting it to sit still enough while your doing all this.
