But Angela Gianakis, an interior and exterior consultant for Outside Square, says functionality is always key.
Take freestanding baths, for example. She says they can look fantastic and are easy to get in and out of, but must also be easy to clean around.
Anyone upgrading their bathroom should think carefully about whether the freestanding bath of their dreams will be very difficult to clean around the back and underneath.
She also points out they need to be placed in a handy location to taps.
''Make sure you can add a bit more warm water without having to get our of your bath,'' she advises.
Frameless showers, which are easy to clean, can be found in many of the most modern bathrooms, but they also need to be carefully thought-out and installed in order to avoid leaks, Ms Gianakis says.
''The preparation for a frameless shower is important in making sure that they function well.''
Ms Gianakis says large windows and plenty of natural light are another trend in bathrooms.
''Lighting and ventilation are very important in a bathroom - we all know that things like to grow in warm areas,'' she says, adding small windows can be just as effective and sometimes more practical
''Remember that if you can see out, people can probably see in,'' .
She says she is not a fan of bathroom window treatments (such as blinds and curtains) because they tend to gather dirt, dust and steam.
Ms Ginakis says neutral-toned bathrooms are in vogue at the moment, but can be jazzed up with coloured feature tiles.
''Timber-look'' tiles are also very of-the-moment, she says. They can feature on a wall or around bathroom joinery.
