This Melbourne-based brand has successfully dominated the premium drink bottle market with its beautiful, customisable designs. But how do they actually perform?
What Is It?
Frank Green makes reusable ceramic-lined water bottles in a range of sizes. A 20oz (595ml) bottle retails at around $59.95 AUD. All made from 304-grade stainless steel with triple-wall vacuum insulation and a ceramic inner lining — designed to eliminate the metallic taste you sometimes get with stainless steel bottles.
The bottles are BPA-free, designed and owned in Australia, and come with either a push-button lid or a straw lid. They're available in an enormous range of colours and can be personalised with monogramming.
What Frank Green Gets Right
The design is genuinely pretty. Frank Green bottles are sleek, modern, and available in colours that actually feel considered — not the rainbow-everything approach you get with some brands. The push-button, one-handed operation lid is particularly loved. And importantly: it is truly leakproof. This bottle can be tossed in your bag alongside your laptop without ruining your life.
Triple-wall vacuum insulation means drinks stay cold or hot for extended periods. The ceramic lining does genuinely make a difference to taste for taste-sensitive people. The range is also modular — you can buy replacement lids, straws, and accessories separately, so you don't need to replace the whole bottle if one part breaks.
The 16oz bottle fits in a standard car cup holder — fact checked and confirmed — which not all drink bottles manage.
The Things People Complain About
Ceramic coatings are typically silicon dioxide-based, applied through a process called sol-gel. These coatings degrade over time, exposing you to the degraded material and whatever the base material is underneath.
These bottles consistently receive reviews noting that when new, the bottle can give water a slightly off or chemical-like taste for the first few uses. Frank Green's own FAQ suggests filling the bottle with baking soda and warm water and leaving it to sit overnight to resolve this.
The bottle base is hand wash only (the lid is dishwasher safe), which adds a little maintenance effort.

💧 Low-Tox Note: If you're concerned about ceramic coatings, see our dedicated post on ceramic vs stainless steel drinkware safety. For daily water bottles, food-grade stainless steel or borosilicate glass are generally the most stable long-term options.
Verdict
Frank Green makes beautiful, well-designed bottles that perform well and will fit in your cup holder. There's a first-use taste issue, but most people move past it. If you want a bottle that's as much an accessory rabbit hole as a hydration tool, Frank Green is a solid Australian brand — but be aware of the ceramic coating considerations if you're going low-tox.
