Sparkling water has quietly become one of the more expensive habits in the average Singapore kitchen. A 1.5L bottle of the branded stuff runs $4 to $8 at the supermarket. Buy 1 bottle daily two a week, and that's $600 to $3000 a year, just for bubbles.
On the contrary, making your own at home works out to roughly 40 cents a litre with SodaStream®. That's how much it costs to make soda water in Singapore, bottled versus homemade. That said, here's the full breakdown, cost by cost, so you can see exactly where the savings come from for a typical household.
What Bottled Sparkling Water Actually Costs You
Branded 1.5L bottles cost $6 to $8 at major supermarkets. Generic supermarket-brand sparkling water is cheaper, usually $1 to $2, though the fizz rarely lasts and the flavour is noticeably thinner. Imported bottles at premium grocers push past $6, sometimes more for known brands. Either way, that cost repeats weekly, with no way to bring it down.
A household drinking two branded bottles 1 bottle daily a week is looking at $600 to $3000 a year, and that's before the extras. Delivery surcharges on online grocery orders. The supermarket trip itself, which somehow always turns into a bigger basket than planned. Then there's the storage problem: a small Singapore kitchen wasn't built for crates of bottles under the sink or beside the fridge, and the recycling bin fills up fast.
What Homemade Sparkling Water Actually Costs
Homemade sparkling water with a SodaStream® works out to around 3040 cents a litre. Most of that cost sits in the CO2 cylinder, which carbonates a set number of litres before it needs swapping, and is refilled at over 30 retail partners across the island. The reusable bottle is a one-off cost, amortised over roughly three years of daily use, so it barely moves the number.
For households that drink more sparkling water, CO2 refill subscription plans are available across SodaStream® Singapore's retail network, so the cylinder swap happens automatically instead of becoming another errand. Either way, once you've got a home soda maker on the counter, the ongoing cost stays close to flat no matter how often you use it.
How Long Until a SodaStream® Pays for Itself?
Here's the maths in one line: a household spending $35 a month on bottled sparkling water pays back a SodaStream® Terra in roughly a year, sometimes sooner. Heavier drinkers pay it back faster still. A household going through sparkling water daily, rather than a couple of nights a week, can see the maker cover its own cost in well under a year.
The savings compound from there. Drink mixes cost roughly the same per glass as store-bought canned soft drinks, but with up to 60% less sugar, so switching doesn't just save on water; it changes the maths on soft drinks too. Browse the full range of soda water flavours to see what that looks like in practice.
The Hidden Costs of Buying Bottled
Bottled sparkling water carries costs that never show up on the receipt. Running out on a Tuesday night with no same-day supermarket run in sight. Counter space and under-sink storage in a kitchen that was never designed for crates. The weekend stockpile that now blocks half a cupboard. The effort of breaking down bottles for recycling, now with a 10-cent BCRS deposit stacked onto every one you buy.
None of this is dramatic on its own. Added up over a year, it's real friction for something that is essentially water and gas.
Is Homemade as Good as Bottled?
Yes, and in some ways it's better. Homemade sparkling water is made fresh, glass by glass, with carbonation strength you control from barely-there to sharp. The advantage of carbonated water goes beyond the cost savings, and making it fresh means you're never drinking from a bottle that's been sitting in a warehouse.
The bigger shift is convenience. Bottled sparkling water means planning around stock, checking what's left, and timing the next supermarket run. Homemade means water on demand, whenever the mood hits, with no stock to run out of. For a full walkthrough, see our guide to making soda water at home.
The Bottom Line
Side by side, the gap is hard to ignore. Bottled sparkling water costs $4 to $8 a litre and a half, roughly $600 to $3000 a year for a two-bottle-a-week household that consumes 1L daily. Homemade costs about 40 cents a litre, closer to $50 to $80 a year for the same habit, with less plastic, less lugging, and one less thing to remember at the supermarket.
That's what the SodaStream® vs bottled sparkling water comparison comes down to, and it isn't close. See the full range of sparkling water makers and work out what your own household could save.
