Love your Circular&Co coffee cup, but wish it kept your drinks hotter or colder for longer? Or perhaps you have a non-lockable lid and want extra leak-proof confidence when you’re on the move? Maybe you just fancy a fresh new look with a different coloured base or lid?

We’ve got you covered! With our interchangeable stainless steel bases, replacement cup bases, and lockable lids, you can easily upgrade or refresh your existing Circular&Co reusable cup without buying a completely new one. It’s the ideal solution to improve your cup’s thermal performance, enhance durability, and reduce waste.

Benefits of our Stainless Steel base:

Sustainable & Cost-Effective

Rather than purchasing a whole new cup, we offer a more sustainable and cost effective option of just purchasing a base. This helps reduce waste and means you can just swap your original lid to a new base.

Seamless Compatibility

Whether you have one of our new lockable or old non-lockable lids (maybe even an original rCup), these are all compatible with the new stainless steel base for easy swapping and interchangeability.

Pick the best size for you as our bases come in all 3 sizes – 8oz, 12oz and 16oz. You can stick with your original size or choose something smaller / larger. So whether you’d like to use your new base for an espresso on the go or to keep a large tea warm for several hours, we’ve got you covered! 

Cup Upgrade FAQs

Are all bases and lids interchangeable?

All the Circular Cup lids and bases are interchangeable (including the non-lockable and lockable versions). Please note: the NOW cups have a different base and lid so are not interchangeable.

Can I mix a stainless steel base with my older lid?

Absolutely! Our stainless steel bases work seamlessly with all previous Circular cup lids.

How long will drinks stay hot or cold with a stainless steel base?

Our stainless steel bases significantly enhance insulation, typically keeping hot beverages warm for around 6 hours.

Are Circular&Co stainless steel bases recyclable?

Yes, our stainless steel bases are fully recyclable, supporting our commitment to sustainability and a circular economy.

How do I know which size base or lid to choose for my cup?

Our lids fit each size of base (8oz, 12oz and 16oz) and you can choose to match your current cup’s capacity or choose a smaller or larger base.

How does upgrading support sustainability?

Replacing or upgrading specific components extends the cup’s lifespan, significantly reducing waste.

Can I put my base and lid in the dishwasher?

Yes, both our stainless steel and standard paper cup bases, as well as lockable lids, are dishwasher safe.
