Speaking of chocolate brown... I love a dash of this color in an all-white bathroom. Think white marble floor, white subway tiles, white Kohler fixtures... This shower curtain from Ballard Designs looks great and is an amazing value at just $42, monogrammed!
It also comes in black, red, sage and taupe.
Then, to match, these "Bel Tempo" Matouk towels... They're quite pricey, but the quality is really nice. I'd skip the monogram on these... I don't like things too overly matchy.
I have the bath mat. I love it. $68 is a lot for a mat though...
