Outdoor Baths & Cold Plunge Tubs

Every tub on this page is a freestanding galvanised steel outdoor bath you fill from the garden tap, soak in, then drain. No plumber and no power point for the default setup. Use it cold as a cold plunge tub, warm as an outdoor bath, or add a fire coil for a wood fired hot tub.

Which outdoor bath suits you?

The Outdoor Bath & Cold Plunge Tub (from $2,195). A 1.8m galvanised steel oval, 0.61m wide and 0.61m deep. It holds about 550 litres at a comfortable level and fits two adults for a soak, or one adult chest-deep for a cold plunge. A custom-fit UV-resistant cover and a drain plug at the back are included. Raw galvanised steel is $2,195 and a painted finish (matte white, matte black, olive green or sandstone) is $2,895. See it on the Outdoor Bath & Cold Plunge Tub page.

The Off-Grid Wood Fired Hot Tub (from $2,795). The same physical tank with a stainless steel coil added. You build the fire inside the coil, the coil heats the water, and the water circulates back into the tub on its own. No pump and no power. It ships with the coil, an insulated cover and a floating thermometer. Painted finishes are $3,495. See the Off-Grid Wood Fired Hot Tub.

Already have a galvanised tub? The Off-Grid Wood Fired Coil Kit ($985) is the coil on its own.

Cold plunge, outdoor bath or hot tub

The tub does whichever job you fill it for. For a cold plunge, fill it from the cold tap and add a few bags of ice in summer. For an outdoor bath, fill it from a hot tap or pre-heat water and bucket-fill it, then soak the way you would in a clawfoot bath, only outside. For a hot soak with no hot tap nearby, the wood fired version heats from cold in about 2 hours with the cover on, so light the fire a couple of hours before you want to get in.

Still deciding between heat and no heat? Our wood fired bath vs wood fired hot tub guide sets them side by side, and using a stock tank as a cold plunge covers the cold side.

What an outdoor bath costs in Australia, all in

• The tub: $2,195 for the Outdoor Bath & Cold Plunge Tub, or $2,795 for the wood fired version, cover included.
• Delivery: free to metro Perth, Sydney, Brisbane and Melbourne, and free to most regional areas too.
• A base: nothing if you already have concrete, pavers or level compacted ground. Otherwise a small gravel or cracker-dust pad.
• Water: about 0.55 kilolitres a fill. At the Perth tier 1 rate of $2.108 per kilolitre that is roughly $1.20.
• Wood, for the hot tub: about $3 to $4 of seasoned hardwood per soak.

The per-bath numbers, with sources, are in our outdoor bathtub running cost guide. For a full buyer's walk-through, read outdoor bath Australia: what to buy, what it costs and where it can go.

Delivery across Australia

Tubs ship free to metro Perth, Sydney, Brisbane and Melbourne, and free to most regional addresses, either to your door or to a nearby depot. A few remote postcodes need a quote, so email hello@terratanks.com.au first if you are well off the beaten track.

The tanks are made in the US and shipped nested inside one another to keep freight costs down. Length and width can vary by up to 2cm from the listed size, and minor scuffs from freight are normal. Neither affects strength or the fit of the cover.

Where an outdoor bath can go

Firm, level ground. Concrete, pavers, gravel or compacted earth. Check it is level before you fill.

Never on a timber deck. 550 litres of water weighs about 550kg before two people climb in, and a standard deck is not built for that. Put the tub on the ground and build the deck beside it.

Wood fired means non-combustible. The hot tub sits on gravel, cracker dust, concrete, pavers, slate or bare earth only, never indoors.

Council and barrier basics

Pool barrier rules under AS 1926.1 look at whether a vessel can hold more than 300mm of water. These tubs have 610mm walls, and draining between soaks does not change that test. How each state and council applies the rule to a tub rather than a pool varies, so ring your council with the dimensions before you order and get the answer for your address. Our state guides show how that conversation goes: WA, NSW, VIC and QLD.

Outdoor bath FAQ

How much does an outdoor bath cost in Australia?

Our Outdoor Bath & Cold Plunge Tub is $2,195 in raw galvanised steel and $2,895 painted, with a cover included.

Do I need a plumber or a power point?

No, not for the default fill and drain setup. The wood fired version heats with fire, so it needs no power either.

Can an outdoor bath go on a deck?

No. A full tub is far heavier than a standard deck is built to carry, and the wood fired tub also needs a non-combustible surface.

Can I try it before I commit?

Every tub comes with a 90-day money-back guarantee from delivery, even if you have used it. You pay the return shipping.
