Modern, white bathtub in bathroom with gray and white tiles.
They’re often the star of a bathroom – here’s how to find a tub that plays the role perfectly.

Soaking hot bathtubs

Bathtubs are the centrepiece of most bathrooms. They need to look good, as well as being functional and practical. With an array of shapes, styles and materials available, there’s a lot to consider before buying a new bathtub. Here are some tips on how to choose the ideal soaker for your new bathroom or bathroom renovation.

Bath styles for every size of bathroom

You may love the idea of a luxurious spa-like freestanding bath but, if space is tight, look at more compact alternatives. Interior designer Trudi Scrymgour (Form Follows Function) suggests inset (built-in) or back-to-wall baths instead. “These styles can be more affordable to buy as well as install,” she adds.

Luke Di Michiel, industrial designer at Caroma, agrees it’s important to balance the size of your bathroom with your choice of bath. “That will mean less chance of the bathtub impacting the traffic and flow to the basin, shower or toilet,” he says.

Choose your soaking style

If you love indulgent soaks and space is not an issue, a freestanding bath could be best. Alternatively, check out the Caroma Newbury inset bath that comes with an optional head and backrest.

If your tub is primarily practical – kids’ bath-times, for example – an inset bath fits the bill. Their design means they have a ledge that’s ideal for keeping shampoos and soaps handy, which freestanding baths don’t have. For freestanding styles intended to float in the centre of a space, you’ll need to position a stool or table within easy reach, or place accessories on a moveable shelf or caddy that sits across the tub.

“In a smaller bathroom, shelves or a wall niche positioned within easy reach of the bath are space-efficient ideas,” says Trudi. “You just need to be careful when renovating an old home, as a wall recess may impact plumbing.”

If your bath is likely to be used by more than one person at a time, choose a model with a central wastewater outlet, so one person doesn’t end up perched on the plug.

Bath types

Inset baths

Also known as built-in baths, these are fitted flush against a wall and enclosed by a customised surround. “This space-saving option can also be integrated with an overhead shower,” says Trudi. “If so, you’ll also need to install a screen or shower curtain.”

Matching tiles on the wall and surround keep the look sleek. “Or try a mix of plain and patterned or coloured tiles to lift a family bathroom,” suggests Trudi.

Back-to-wall baths

These models, sometimes called D-shape baths, are a blend of inset and freestanding baths. “For those who love the look of a freestanding bath, but don’t have the space in the bathroom, a solution is a D-shaped tub that looks like it is freestanding from the front but actually sits flush against the wall,” says Luke. “This saves space and also means you don’t need to clean behind it.”

In addition, their design means these can be easier to plumb.

Freestanding baths

Deep, freestanding baths in striking shapes – rectangular, oval and slipper style – have grown increasingly popular because they make a strong design statement. However, due to their generous dimensions, they need plenty of room, says Luke. “Bear in mind freestanding baths need space around them so you can fit a mop or vacuum cleaner,” he says.

Bathroom plumbing options

If you’re doing bathroom renovations, it’s crucial to remember your existing plumbing may not be easily compatible with the type of bath you want. Inset baths are much easier to plumb in as they sit against the wall and their pipework is hidden behind the surround.

For freestanding baths, you need to consider the tapware and wastewater location. “Freestanding baths generally require the installation of a freestanding bath filler, which needs specialised floor mounting and water supply access via the floor,” says Luke. “This might not be possible for all installations.”

Bathtub material types

Most baths tend to be made from acrylic, which Luke notes is usually more affordable and lighter than alternative materials and has good heat-retention properties. Solid surface baths – those with a smooth, seamless, non-porous finish made from engineered composite materials such as natural minerals and resin – are also popular.

Note that heavier styles, such as freestanding natural stone baths, can weigh up to 500kg, so the floor it is going to sit on may require structural reinforcement under the supervision of a structural engineer.

Health & Safety

Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.
