Buy some big, thick, fluffy towels, even if you don't use them they will look lovely.
Buy some matching candle sets for the side of the bath or for on top of the lav.
Try to avoid those little knitted dolls for your loo roll however (ha, ha, ha).
Buy some nice inexpensive pictures that you can hang on the wall and accent the other colors in the room or if you have a little artist in yourself paint your own pictures to match! ;)
