Resort suites are all about indulgence and relaxation. So, too is this master suite, which was modelled on a tropical resort retreat.

Architect Martin Grounds of Grounds Kent Architects and interior designer Christian Lyon of Christian Lyon Design worked closely with the owners and the builder Gage Roads Group to ensure the suite would not only be luxurious and contemporary, but would also maximise a great view.

Grounds says the suite was designed around the piéce de resistance a large stone tub carved from a single piece of volcanic rock from Java.

"The tub, which has been highly polished both inside and out, is an art work in itself," the architect says. "It introduces a strong organic form to contrast with the sleek, Carrara marble tiles on the walls and floor."

Lyon says the hewn rock also provides a visual reference to a huge limestone cliff in front of the property, which is essentially part of the fabric of the house.

The tub is positioned beside a full-height glass wall, so the owners can enjoy the view while bathing. And it's not the only fixture to be placed to maximise the view. The toilet room also looks out to the river in the distance.

To enhance the modern, spacious feel of the bathroom, the vanity is cantilevered it appears to be suspended in front of a mirrored glass wall.

"The floating effect created by the vanity enhances the strong horizontal lines of the architecture," says Grounds.

Bevelled mirror panels on either side of the vanity provide glittering, multifaceted reflections of the natural light and view. They also counter the more masculine look of the stone tub, says Lyon.

A large double shower, designed as a wet room with a trench drain, features glass walls that provide a view to a private courtyard. The controls and plumbing for two showers, including a rainhead shower, are positioned on Carrara marble columns that resemble plinths. Recessed shelves within the marble can be used for toiletries.

There is also an outdoor shower in the walled courtyard, which further enhances the sense of a private tropical resort hideaway.
