SodaStream vs HydroSpark+: Which Fits Your Singapore Home?

SodaStream and Velta HydroSpark+ both make sparkling water, but they belong in different buying categories. SodaStream is a compact carbonator starting at $219.90. HydroSpark+ is a S$2,988 countertop reverse-osmosis purifier and dispenser that also provides hot, chilled, ambient, and sparkling water.

If carbonation is all you need, SodaStream is the sensible answer for most homes. HydroSpark+ only enters the conversation if you are already comparing water purifiers or temperature-controlled dispensers.

How We Compared Them

This is a researched comparison, not a claim that we hands-on tested every SodaStream model. We checked the official Singapore product range, prices, cylinder information, and Velta's HydroSpark+ specifications on 14 July 2026.

Velta sells HydroSpark+, so we have a commercial interest in this comparison. That does not change the large price difference or the fact that SodaStream is the better-value choice for carbonation alone.

The Short Answer

• Choose SodaStream for the lowest upfront cost, a small footprint, manual models that need no power, and an established Singapore cylinder-exchange network.
• Choose HydroSpark+ if you want one countertop machine for RO-filtered ambient, hot, chilled, and sparkling water and would otherwise buy those functions separately.
• Choose neither yet if you are unsure how often you will drink sparkling water. Start by estimating your current bottled-water use and the counter space you can give up.

Feature Comparison

The current SodaStream Singapore maker range includes the manual Terra and Art plus the electric E-Terra. HydroSpark+ is one larger appliance rather than an under-sink unit: it measures 220 × 508 × 436 mm and weighs 21.7 kg.

Price and Ongoing Cost

SodaStream

When checked, the official range listed:

SodaStream Singapore's CO2 page listed a $29.50 exchange price and up to 60 litres per cylinder. Actual yield depends on how cold the water is and how strongly you carbonate it.

HydroSpark+

HydroSpark+ is S$2,988. The machine includes purification, heating, chilling, and carbonation hardware. Its ongoing costs include the composite RO cartridge, CO2, and electricity.

CO2 cost alone does not make a useful comparison between these machines. HydroSpark+'s five-year cost also includes the current filter price and recommended replacement interval, set against the separate purifier, hot-water dispenser, chiller, and carbonator you would otherwise buy. If you do not need those other functions, the calculation strongly favours SodaStream.

Space and Setup

SodaStream is easier to place and move. The manual models need no outlet or plumbing, but you need room above the machine to operate it and space to store its bottle. If you want filtered water, you filter it separately before filling the bottle.

HydroSpark+ needs substantially more counter depth and a nearby power outlet. Tank mode lets you refill the removable 5L source tank by hand, which can suit a rental or a counter without a convenient water line. Pipe-in mode automates source-water refilling but requires a suitable connection. A site assessment establishes the clearances and installation route.

Water Quality and Taste

PUB states that Singapore tap water is suitable for drinking directly without further filtration. A purifier is therefore optional, not a requirement for safe tap water.

With SodaStream, the starting water is your choice: chilled tap water, water from an existing purifier, or bottled water. HydroSpark+ filters the source water through its composite RO cartridge before dispensing it. The practical reasons to choose that setup are taste preference, a desire for low-TDS water, and the convenience of combining appliances—not a claim that ordinary Singapore tap water is unsafe.

Which One Should You Buy?

SodaStream is the better fit when:

• You only want sparkling water.
• You want to spend under $400.
• You rent or move frequently.
• You already own a purifier or are happy with tap water.
• You want a widely published local cylinder-exchange network.
• You have limited counter depth.

HydroSpark+ is the better fit when:

• You are already buying a water purifier and temperature-controlled dispenser.
• You regularly use ambient, hot, chilled, and sparkling water.
• You prefer one supplier for the machine, filter, CO2, warranty, and servicing.
• A 220 × 508 mm countertop footprint works in your kitchen.
• You have compared the full five-year cost, not just the purchase price.

Frequently Asked Questions

Can I use Singapore tap water in a SodaStream? Yes. PUB says Singapore tap water is suitable for direct drinking. SodaStream instructs users to carbonate plain, cold water and add flavour afterwards.

Does HydroSpark+ go under the sink? No. It is a countertop machine. It can use a removable source-water tank or a pipe-in connection.

Does HydroSpark+ need professional installation? Tank mode does not need a permanent water connection. Pipe-in mode does. A Velta site assessment covers the water connection, power outlet, counter clearances, and drainage requirements for the intended setup.

Can the two machines share CO2 cylinders? Not necessarily. Current SodaStream Terra, Art, and E-Terra models use the pink Quick Connect format. The cylinder type and exchange arrangement need to match each machine.

Is HydroSpark+ worth S$2,988? Not for carbonation alone. It may be worth comparing if you are already planning to buy an RO purifier plus hot, chilled, and sparkling dispensing. Velta's Keong Saik Road experience centre has the functions available to try, along with current recurring costs.
