When you want to improve an existing bathroom that’s tiny and dark, sometimes the only way forward is to create an addition to contain a totally new master suite.

And if that’s the way you go, one of the issues to then resolve is the aesthetic connection between the old and the new.

Designer Mark Williams designed the master bathroom shown here as part of an addition to a traditional-style 1940s home.

“The owners wanted their new bathroom to look like it had always been there, and not like an addition,” says Williams.

“But it still had to function in a very, very contemporary way.”

To link in with the original home’s classic design, Williams selected a variety of natural stone floor and wall tiles, and a colour palette of black, white and grey – a combination that, he says, never dates.
