Welcome to Fire Hot Tubs (NZ) Ltd.....

....home of New Zealand and Australia's best priced Canadian cedar hot tubs and bath tubs.

About us:

We are an Auckland, New Zealand based company that has been supplying cedar hot tubs and bath tubs all over New Zealand and Australia since 2010.

Our speciality is providing you with our high quality New Zealand made hot tubs and bath tubs at a very competitive price.

We originally imported our hot tubs and wood-fired burners from overseas but we now hand-craft all our hot tubs in New Zealand.

Also, we originally only sold only wood-fired hot tubs (hence the word "Fire" in our name) but we now sell 3 different heating options as mentioned below.


Different heating options available:

  • Wood-fired internally submerged burner: Designed and made in New Zealand. Made of 2mm marine grade #316 stainless steel. 2 year warranty.
  • Electrically heated: Electric pump with a cartridge filter and a choice of either a 2.3kw or 5.5kw efficient heater. All plumbed together on a base. 2 year warranty.
  • Dual heated (gas and wood-fired) externally connected burner: Designed and made in New Zealand. Made of copper. 5 year warranty.


Tub sizes:

  • Ellipse shaped 2-4 person hot tub: 1680mm long x 1260mm wide x 785mm high 2 person
  • Small sized hot tub: 1450mm wide x 1250mm high 4 person
  • Medium sized hot tub: 1650mm wide x 1250mm high 6 person (most popular size)
  • Large sized hot tub: 1850mm wide x 1250mm high 8 person


Our tubs:

We only use high quality A-grade, knot-free Canadian Western red cedar on all our hot tubs.
The threaded rods and bands around the hot tub and other components are made from marine grade #316 stainless steel.

Each cedar tub is manufactured to exacting specifications.
Our hot tub staves are precision milled with ball and socket joints.
Our ball and socket joints provide more sealing surface than butt stave joints.
The cedar hot tub bottom boards that make up the base are invisibly secured with wedged tongue and grooved joints which produce an extremely strong and smooth surface.



Tips on choosing your hot tub:

A hot tub is a major purchase that becomes a long-term household fixture.

A hot tub must be sized correctly so that it fits a prepared space and is suitable for the amount of people who will be using it.

When shopping for a new tub, the buyer should have a base of knowledge about the equipment that inspires the right questions.


About hot tubs

Hot tubs are usually located in an outdoor setting. They are constructed of cedar and contain heated water. A soak in a hot tub helps users soothe aching muscles and steam away stress. Many find the temperature difference between cool outdoor air and the heated water exhilarating.

Electric, gas or wood-fired heaters keep water hot and soothing. Our tubs come with integrated heaters or you can buy one of our tubs and add your own heating system. Our tubs all have the option to add filtration systems that circulate water to remove debris and to keep the water crystal clear.

Some owners fill and drain their hot tubs between uses but most sanitize the water in the tub and reuse it repeatedly by using one of our pump and filter units. The most popularly used chemicals for eliminating water-borne bacteria and neutralizing odour are chlorine and bromine but we can also offer Simple Silver natural, chemical free water treatment solution which costs $395.00 for 1 year's supply.

Our hot tubs generally come with 2 adjustable outlet jets that direct concentrated flows of water. More jets can be added to suit. These jets massage user's muscles and ease their tension. Users can turn the jets off or on as desired. Bubbles can also be added if so desired.

Why we use only A-grade Canadian Western Red Cedar?

  • Western red cedar is famed for its extraordinary durability and resistance to decay. It contains natural preservatives that resist moisture, decay and insect damage.
  • Cedar has the ability to withstand extreme temperature variations including moisture and heat. It's the first choice of wood in areas with severe winters and hot summers. Frankly, a hot tub made from Western red cedar will serve you many years and will remain beautiful and troublefree.
  • Cedar's unique aroma also comes from naturally occurring thujaplicins in its heartwood. It's pleasing odour is a repellent to moths, insects and vermin.
  • Western red cedar has a very low coefficient of expansion. So, unlike other soft wood such larch or spruce,  it does not shrink, swell or warp excessively, even when subjected to changing degrees of temperature and moisture
  • Western red cedar has prime insulating qualities, which makes our hot tubs very economical to heat. No other wood has the insulating value of Western Red Cedar.
  • And of course it is very beautiful to look at. So if you are looking for the best material possible, western red cedar is the answer!


Cedar hot tubs vs plastic spa pools

  • More relaxing: the water surrounds the bather more because of the deep vertical walls resulting in a far more relaxing experience.
  • Healthier: cedar has natural anti-bacterial preservatives, plastic does not.
  • Beauty: a cedar hot tub is a thing of beauty. Not only is the geometric shape appealing, the rich colours and grains in the wood are visually stunning and will look great, either in your back yard.
  • Aromas: since your hot tub experience is one that is meant to appeal to your senses, cedar hot tubs exude a pleasant and natural aroma when hot and wet so this is another great reason to go with a cedar hot tub. Unfortunately, synthetic plastic spas tend to give off only chemical and artificial aromas.
  • Durability: cedar is legendary for it's softness and durability. Will last 20+ years.
  • Natural insulator: unlike plastic, wood and especially cedar is a natural insulator. The cellular composition of cedar is made up of millions of tiny air-filled cells which provide natural thermal insulation. Heating the water is therefore quicker and stays warmer for longer periods.
  • Cheaper to run: generally speaking, plastic spas come with many jets and bubbles as each different spa pool company try to out do each other by offering more of these. While they may seem all nice to have, more jets require more power and more bubbles adds more cold air into the water which obviously cools the water quickly and so requires more electricity to heat up the water.
