Water Flosser: Kmart vs Chemist Warehouse Price Guide
Reviewed by the waterflosser.au editorial team · Published May 2026 · Updated August 2026 · 8 min read
Kmart and Chemist Warehouse are two of the most-searched places to buy a water flosser in Australia, and they serve pretty different shoppers. Here's how they actually compare on price, range and what's usually in stock.
Kmart
Kmart's water flosser range leans budget — generic and house-brand cordless models generally sit in the $20–40 AUD range. It's a solid option if you just want to try water flossing without committing much money, but the range of name brands like Waterpik or Philips is limited, and stock varies a lot by store.
Chemist Warehouse
Chemist Warehouse stocks more recognisable dental brands — Waterpik, Colgate and Panasonic all show up regularly — usually priced between $40 and $120 AUD depending on the model. Being a pharmacy, they also tend to run more frequent sales and multi-buy deals on oral care, so it's worth checking current pricing before you buy.
What about replacement tips and accessories?
This is where Chemist Warehouse pulls ahead as a longer-term option: because it stocks named brands, replacement tips and accessories for those models are more consistently available in-store. Kmart's generic house-brand units are more likely to become hard to find replacement parts for once a particular model is discontinued.
Our recommendation
For the widest selection and the easiest way to compare current prices without driving between stores, Amazon AU is usually the most efficient option — you can check today's price, read recent reviews, and have it delivered rather than hoping your local store has stock. Use our comparison table to check specs first, then follow the Amazon link for current AU pricing.
Frequently asked questions
Is Kmart's generic water flosser any good?
For occasional or light use, generic budget flossers from Kmart are generally functional, though they typically have fewer pressure settings and less robust build quality than named brands. They're a reasonable low-commitment way to try water flossing.
Does Chemist Warehouse price-match other retailers?
Policies vary by store and change over time, so it's worth asking in-store or checking their current policy directly rather than assuming — this isn't something we can verify site-wide.
Can I return a water flosser to Kmart or Chemist Warehouse if it doesn't work for me?
Both generally follow standard Australian Consumer Law return rights for faulty goods, plus their own change-of-mind policies which vary. Keep your receipt and check the specific store's current returns policy before buying if this matters to you.
