Soda Maker vs Sparkling Water Maker: What Is the Difference

Key takeaways

• A ‘soda maker’ and a ‘sparkling water maker’ usually use the same basic CO₂ cylinder technology; the difference is how they are marketed and tuned for either plain water or sweet, flavoured drinks.
• Machines sold as sparkling water makers often emphasise simple carbonation of chilled water, like the compact FizzIt-style one-touch sparkling water machines, while soda makers lean more on syrups and soft-drink style fizz.
• For health-focused drinkers, a sparkling water-first machine encourages low- or no-sugar recipes, but soda makers can still be used purely for water if you ignore the syrups.
• Both types use broadly similar CO₂ cylinders, so cost per litre depends more on how much fizz you prefer and how cold your water is than on whether the box says ‘soda’ or ‘sparkling water’.
• If you mainly want plain fizzy water, choose a simple sparkling water machine; if you also love cola-style drinks, a soda maker with good syrup compatibility and carbonation control gives more flexibility.

Soda maker vs sparkling water maker: what do the terms really mean?

The biggest source of confusion is that both soda makers and sparkling water makers do exactly the same core job: they inject pressurised carbon dioxide into water to create bubbles. There is no separate technology for making ‘soda’ and another for making ‘sparkling’ water.

In practice, the difference is mostly about emphasis and how the machines are set up and marketed.

• Soda maker usually suggests a machine aimed at recreating fizzy soft drinks. The branding focuses on cola, lemonade and flavoured recipes, with lots of talk about syrups, mocktails and replacing canned drinks.
• Sparkling water maker leans towards plain or lightly flavoured fizzy water. The marketing is more about hydration, cutting sugar, and reducing bottled water waste.

Under the casing, both usually use a similar CO₂ cylinder and bottle system. A model like the SodaStream Art is sold as a sparkling water maker, but you can still add syrups afterwards to make full-on soda. Likewise, a machine sold as a soda maker will happily carbonate plain filtered water without any flavour at all.

The label on the box is less important than how you intend to use the machine. Think about your favourite drinks first, then check which features support them.

How drink styles differ: fizzy soft drinks vs clean sparkling water

When you are deciding between a soda-focused machine and a sparkling water-focused one, the key question is what you want in your glass most of the time.

If you love classic fizzy soft drinks

Fans of cola, lemonade and fruit-flavoured fizzes tend to be better served by a traditional soda maker. These machines are usually designed with:

• Higher carbonation potential, so you can get that sharp, biting fizz that stands up to sweet syrups.
• Wide syrup compatibility, with dedicated concentrates and sometimes recipe suggestions for recreating favourite flavours.
• More robust bottles that are comfortable for repeated, strong carbonation cycles.

Machines like the SodaStream Terra sparkling water maker sit in an interesting middle ground: they are sold as sparkling water makers, but they work brilliantly as soda makers when paired with syrups, thanks to their powerful carbonation and quick-connect cylinders.

If you mainly want clean, sparkling water

If your goal is to drink more water and less sugar, a sparkling water-focused machine keeps things simple. These models often highlight:

• Effortless one-touch carbonation, sometimes with a single fizz level so you cannot really overdo it.
• Simple, minimal designs that look at home next to a kettle or water filter rather than on a cocktail bar.
• Subtle flavouring options, such as a slice of citrus or a few drops of natural flavouring rather than thick syrups.

A compact machine such as the grey FizzIt one-touch sparkling water maker is an example of this style: you attach the CO₂ canister, fill the reusable bottle, press once and you have a glass of bubbly water ready to drink.

Both approaches can live in the same kitchen. Some people keep a ‘daily driver’ sparkling water maker on the counter and treat a more feature-rich soda maker as their weekend or entertaining machine.

Syrups, flavouring and compatibility

One of the more practical differences between soda makers and sparkling water makers is how they handle flavour. If you know you will use syrups, this section matters more than the branding.

Using syrups and concentrates

Most modern machines, whatever they are called, follow the same basic rule: you carbonate water only, then add syrup afterwards. This protects the machine’s internals and stops sticky liquids from being pushed back into the mechanism.

Soda-focused machines tend to support:

• Higher syrup loads, with bottles and instructions designed around recommended mixing ratios.
• Branded syrup ranges, which make it easy to reproduce familiar flavours without trial and error.
• Regular heavy use, as many households use them to replace canned drinks entirely.

Light flavouring and infusions

Sparkling water makers are perfect for subtle infusions: think lemon slices, cucumber, herbs or a splash of cordial. In these cases, most people:

• Chill plain water.
• Carbonate it in the machine.
• Add natural ingredients or a small amount of cordial in the glass or serving jug.

Machines like the SodaStream Art work well here, because you can control the fizz level with the lever for different styles of drink: less for lightly flavoured water, more for sweeter sodas.

Whether your machine is labelled as a soda maker or sparkling water maker, always check the manual for flavouring guidance. The golden rule is to only carbonate clean water inside the bottle.

Carbonation controls: subtle bubbles vs punchy fizz

The way a machine lets you control carbonation is where the soda vs sparkling water divide becomes clearer in daily use. There are three common approaches:

• Single-level fizz: one press gives one standard level of bubbles.
• Manual multi-press: you press and release multiple times to increase the fizz.
• Lever- or dial-based control: you hold or set a level for more precise and repeatable carbonation.

Sparkling water makers aimed at convenience often stick to single-level carbonation. This is ideal if you just want a reliable glass of fizzy water with minimal thought. Some one-touch models will stop automatically at a pre-set level.

Soda makers and higher-end hybrid machines tend to give you more power and flexibility. The SodaStream Art, for example, uses a manual lever so you can easily create a light fizz for gentle sparkling water or a much punchier level for cola-style drinks. The Terra uses a button-based approach but still lets you build up carbonation in stages.

If you know you are particular about bubble size and intensity, prioritise a machine with good manual control, even if it is sold as a sparkling water maker. If you just want something quick and easy, a simple one-touch sparkling water machine will suit you better.

CO₂ cylinders, usage and cost per litre

Both soda makers and sparkling water makers rely on compressed CO₂ cylinders. From a cost perspective, two factors matter far more than the label on the front of the machine:

• How fizzy you like your drinks.
• How cold your water is before you carbonate it.

Colder water absorbs carbon dioxide more efficiently, so you get more fizzy litres per cylinder. If you mainly drink strongly carbonated soft drinks, you will naturally go through gas faster than someone who prefers a gentle sparkle.

Machines like the FizzIt-style one-touch sparkling makers or the SodaStream Terra typically promise around dozens of standard bottles per cylinder under average use. In reality, if you consistently aim for very strong fizz, you may see fewer servings; if you mostly produce lightly sparkling water, you may get more.

Either way, homemade carbonation almost always works out cheaper per litre than buying equivalent bottled sparkling water or cans of fizzy drink, especially if you choose reusable bottles over single-use plastic.

Health, sugar and ingredients

From a pure carbonation perspective, soda and sparkling water are identical: both are simply water plus CO₂. The health differences come entirely from what you add afterwards.

With a sparkling water maker, the expectation is plain water or lightly infused flavours. This naturally leads to:

• Lower sugar intake if you skip sweet syrups.
• Greater control over ingredients, especially if you pair your machine with a water filter.
• Support for hydration habits, as many people drink more water when it is fizzy and interesting.

A soda maker does not have to be unhealthy, but because the branding leans towards soft drinks, it is easier to end up using more sugary syrups. You can mitigate this by using low- or no-sugar concentrates, flavouring with fruit instead of syrup, or alternating between plain sparkling water and flavoured drinks across the day.

If your main aim is to cut sugar, a machine that is clearly positioned as a sparkling water maker can serve as a daily reminder of that goal. The hardware is similar, but the way you mentally frame it can make a difference.

Design, bottles and kitchen space

There are also some subtle design cues that often separate soda makers from sparkling water makers. These do not change how the machine works, but they affect how well it fits into your kitchen and lifestyle.

• Aesthetic: soda makers sometimes lean into bold, colourful or retro designs, like the lever-driven SodaStream Art, while sparkling water makers often favour clean, minimalist lines to match other countertop appliances.
• Footprint: sparkling water-first models prioritise compact footprints and easy storage, which is handy if you are working with a small kitchen. For more ideas, you can browse our overview of the best compact soda makers for smaller spaces.
• Bottle types: some soda makers offer larger bottles for family serving sizes; many sparkling water makers focus on slim, fridge-friendly bottles for personal use.

Whether you choose soda or sparkling water branding, it is worth thinking about which bottle material you prefer. If that is an open question for you, our guide on glass vs plastic bottles for home soda makers covers durability, taste, and handling in more detail.

Manual vs electric: does it affect soda vs sparkling water?

Most countertop soda and sparkling water makers are manual: you press a button or pull a lever, and the CO₂ cylinder supplies the pressure. Some higher-end machines are electric, handling timing and carbonation levels automatically.

The manual vs electric distinction does not map directly onto soda versus sparkling water, but it does influence the experience:

• Manual machines are simple, require no power, and fit easily into most kitchens. They suit both plain sparkling water and classic sodas. A manual lever model such as the SodaStream Art offers excellent control for both drink styles.
• Electric machines add convenience, pre-set fizz levels and sometimes extra features like automatic stop. They are great for households where everyone wants the same result every time, but they do need a power socket nearby.

How three popular machines fit into the picture

To make the distinctions more concrete, it helps to look at how real, popular machines line up against the soda vs sparkling water divide. Below are three examples that many home users consider.

SodaStream Terra: everyday sparkling water with soda options

The black SodaStream Terra is marketed primarily as a sparkling water maker, but in everyday use it straddles both worlds. It uses a quick-connect CO₂ system and comes with a reusable BPA-free bottle, making it well suited to frequent, daily hydration.

Because it offers firm, repeatable carbonation and plays well with a wide range of syrups, it effectively doubles as a soda maker. If your household wants plain sparkling water most of the week but would occasionally like to mix up colas or lemonades, a Terra-style machine is a strong compromise.

SodaStream Art: retro soda bar feel with precise fizz

The SodaStream Art has more of a soda-bar aesthetic thanks to its retro styling and manual lever. In terms of function, it is still a sparkling water maker at heart, but the lever control and sturdy build make it particularly satisfying for those who enjoy experimenting with different fizz levels and soda recipes.

If you like the idea of a statement appliance that looks as good next to a cocktail shaker as it does beside the kettle, and you are likely to mix both sparkling water and flavoured fizzy drinks, the Art design leans closer towards the ‘soda maker’ end of the spectrum while fully supporting plain sparkling water too.

Compact one-touch sparkling water makers: water-first, soda-optional

Machines like the grey FizzIt one-touch sparkling water maker are unapologetically water-first. They concentrate on simplicity: no power required, a compact footprint, a single reusable bottle and easy, one-button carbonation.

You can still add syrups or cordials after carbonation if you want soda-style drinks, but the user experience gently nudges you towards plain or lightly flavoured sparkling water. For smaller kitchens or people who want to keep things minimalist, this style of machine is a neat, sparkling water-focused choice that can still support occasional sodas when desired.

Which should you choose: soda maker or sparkling water maker?

When you strip away the marketing language, there are three simple questions that will normally guide you to the right type of machine:

1. Do you mainly want plain sparkling water, or are you equally excited about classic fizzy soft drinks?
2. How much control do you want over carbonation levels?
3. How important are design, footprint and bottle style to you?

Choose a sparkling water maker if:

• You mostly drink water and only occasionally fancy a flavoured fizz.
• You want a compact, easy-to-use machine with simple carbonation behaviour.
• Cutting sugar and replacing bottled water are your main priorities.

Choose a soda maker (or a hybrid with soda-friendly features) if:

• You regularly drink cola, lemonade or fruit sodas and want to replace canned drinks.
• You value strong, adjustable fizz and good syrup compatibility.
• You would enjoy playing with recipes, mocktails and different flavour combinations.

Machines such as the SodaStream Terra and SodaStream Art sit comfortably between the two labels, giving you sparkling water simplicity with soda-making muscle when you need it.
