No pun intended, but stools in the bathroom are a must. They lend you that extra surface area to rest a towel, robe, candle, or any other bathroom necessity. They are small enough to squeeze under a cabinet or vanity, set next to a tub, or float near a sink.
They can be bright green metal, upholstered and patterned, ceramic, or rustic wood.
I have a leather tufted cube in my bathroom and it makes me incredibly happy. I lay my towel on it and it's an arm's length away when I need it.
