Bath fillers can look fantastic as shown in this image of the new Cascade filler by Duravit. Water simply cascades out of a chromed inlet on the sloped edge of the bath to provide a wide surge of water.
Hangrohe do a discreet bath filler called the Exafill which can also be thermostatically controlled. This is placed above the overflow on a bath, leaving plenty of room for relaxing without any taps cutting into you!
