A towel bar is the accessory people touch most and specify last, which is backwards. It is at hand height, it carries weight, and it is the piece that shows whether the metal in a bathroom was chosen or accumulated.
These run from 12 to 24 inches. The short ones suit a powder room or the wall beside a basin. The 24 inch bars are for a main bathroom where a full bath sheet needs to hang without folding over on itself, which is the usual reason a towel never dries.
All of them are solid brass under the plating, and all of them mount to the wall rather than clipping to glass or a rail. That matters because a loaded towel bar is under constant leverage, and a hollow one works loose within a year.
Every bar here has a matching towel ring, robe hook and toilet paper holder in the same finish, so a bathroom can be fitted out in one order.
