2000ml thermoTANKA – Our biggest insulated bottle. Like the megaTANKA, but with advanced vacuum insulation technology to keep drinks hot or cold for hours.

ecotanka thermoTANKA – Pure stainless steel. Premium performance.
Discover the ecotanka thermoTANKA series—where precision engineering meets sustainable innovation. Proudly established in New Zealand in 2005, ecotanka pioneered the original 800ml double-wall vacuum stainless steel bottle (originally known as the PolarTanka), setting a new standard long before imitations followed.

Spanning sizes from 350ml to 2000ml, the thermoTANKA range is crafted from high-quality 18/8 304 food-grade stainless steel for unmatched durability, safety, and sleek design.

At the core of every thermoTANKA is our advanced vacuum insulation technology, designed to keep drinks cold for up to 24 hours or hot for up to 12 hours. The wide-mouth opening makes adding ice cubes easy, while priming the bottle with boiling water for 5 minutes before use enhances heat retention for hot beverages.

More than just a bottle, the thermoTANKA series reflects a commitment to sustainable living. By choosing reusable, fully recyclable stainless steel, you’re helping reduce plastic waste and protect the planet—one refill at a time.

2000ml thermoTANKA – Maximum capacity, minimum compromise.

With a massive 2000ml capacity, it's built for endurance and convenience. Pair it with the optional Mega Stainless Steel Lid for a premium finish that’s as tough as the bottle itself.

The ecotanka Mega Stainless Steel Lid (MSS)
