What should I look for when buying a indoor spa pool?

Any spa pool can be an indoor spa pool, so your choices won’t be limited if you plan to place your machine in a sunroom, gazebo or granny flat. There are however a few considerations that are unique to indoor spa pools: you may be looking for a more compact machine, you’ll want to minimise the smell of chemicals, and a firmly fitting cover will help to keep the moisture in. Other considerations include:

What is an indoor spa pool?

An indoor spa pool (or indoor swim spa) is exactly that: a spa pool that is placed indoors. These machines are different to the indoor spa baths found in bathrooms: rather than being drained and refilled for every soak, an indoor pool and spa features treated, heated water that lasts months at a time. They also feature more hydromassage jets, more entertainment features, and are usually built for more people.

In Hot Spring spa pools and Endless Pools swim spas you have indoor spas that feature clever water care technologies that reduce the reliance on chemicals (which can make all the difference in a confined space), and that are the most energy efficient on the New Zealand market, with running costs as low as $1 a day.

Benefits of indoor spa pool

There are a wealth of benefits that come with choosing an indoor spa pool or small indoor swim spa over an outdoor installation:

  • Privacy: Lower the blinds and you can enjoy your Hot Spring indoor spa pool without worrying about neighbours or passers-by peering in – move from the spa to the bathroom or the bed in complete privacy.
  • Convenience: In the icy depths of winter, the short walk from your back door to your spa pool can feel rather inconvenient. There are no such worries with an indoor spa pool, as you’ll be able to reach it without running the outdoor gauntlet – no footwear or even clothing required!
  • Protection: Enjoy your indoor spa pool no matter the weather – if it’s raining, hailing, snowing, or the UV or pollen count is extreme, it simply doesn’t matter. What’s more, the super robust cabinet, shell and cover of your Hot Spring won’t be exposed to the elements, so could last even longer.
  • Make use of space: Do you have an empty nest, or a room that is sitting idle? A Hot Spring indoor spa pool can transform it into a luxurious escape, and one of the most popular rooms in your house!

What size is an indoor spa pool?

An indoor spa pool is whatever size you want it to be. At Hot Spring we offer a market-leading range of models – You can be confident that there will be a machine that fits exactly where you need and offers all the features that you want.

In terms of size, the smallest Hot Spring model is the two-person Freeflow Spas Mini, with a footprint of just over 2m². Our largest indoor spa/hot tub is the Limelight Prism, at around 6.5m². The Endless Pools indoor swim spa range, meanwhile, spans the 8.3m² R200 up to the 13.8m² E2000.

Dozens of models sit in between, offering a wealth of options in terms of size, shape, features and soaking experience.

What are hot tub shells made from?

Hot tub shells have two main functions: to keep the water in and to keep the water warm. Shells come in a variety of materials, each with its own strengths and weaknesses:


Used in most swimming pools, vinyl’s cost-effectiveness makes it a cheaper choice for hot tubs too. It doesn’t retain heat well, nor is it particularly durable.

Rotomoulded plastic

This process sees plastic powder heated and spun in a mould. The result is lightweight, cost-effective and far more durable than vinyl.


The Rolls-Royce of hot tub plastics. Although you pay more for acrylic, you’ll enjoy a spa that is both beautiful and durable. However, it is important to note that not all acrylic hot tubs are created equal.


There’s no arguing that wood looks great, but you’ll pay for the looks with endless maintenance, both on the inside and the outside of the tub. 

Key features of an indoor spa pool

The very best indoor spa pools share a few key features. As New Zealand’s oldest, most trusted and most innovative spa pool brand, our machines include such features as:

  • Unparalleled massage: With significant investments in spa jet research and development, Hot Spring machines are built to deliver the ultimate hydromassage. Every jet is carefully designed and strategically placed for maximum relaxation and relief.
  • Worry-free water care: Water is the defining feature of any spa pool, and if you choose your machine wisely, you can keep your H2O fresh for months, or in the case of our FreshWater Salt System, up to a year!
  • NZ’s most efficient spa pools: Hot Spring spa pools are filled with dense, ultra-efficient insulation that keeps water warmer for longer. In fact, we offer NZ’s most efficient indoor spa pools, costing as little as $1 per day to run!
  • Unmatched customer care: The key to elevating your spa pool ownership experience, to minimise the work and maximise the play, is to have experts on hand whenever you might need them. Our nationwide network of dealers is always on hand to help.

Installing an indoor spa pool

If you choose to install an indoor spa/indoor pool, the key consideration is ventilation. All spa pools use chemicals to keep their water clean, clear, soft and fresh, and these chemicals give off a scent when they’re active – the classic smell of chlorine that reminds us of lazy days at the pool.

By choosing a Hot Spring fitted with high-end water care like the FreshWater Salt System or FreshWater Ozone System, you can significantly reduce these chemical vapours and smells, as these systems use salt or ozone to sanitise your spa more organically and reduce your reliance on chemicals. This makes them ideal for indoor installations.

Plumbing is another key installation consideration, as your indoor spa pool will need to be drained and refilled from time to time. Once again, our FreshWater Salt System can prove a fantastic investment, extending the life of your water from a few months to up to a year.

Indoor spa pool maintenance

By choosing a Hot Spring indoor spa pool, you get a machine fitted with high-end technologies designed to reduce the work of spa pool ownership, leaving you more time to enjoy your investment.

Water care technology such as no-bypass filtration, easy-change cartridges, and salt and ozone systems make upkeep easy and can reduce the need to drain and refill your spa pool.

Add in an unmatched soak, stunning designs, the latest technology, unbeatable quality and energy efficiency, and local dealers that are ready to help whenever you might need them, and a Hot Spring is the finest indoor spa pool money can buy.

Are indoor spa pools high maintenance?

No, because placing your spa pool indoors protects it from the elements. Add in Hot Spring’s market-leading water care technologies, and your spa can almost take care of itself.
