How do your two water bottles differ?

The difference between the two bottles primarily lies in their insulation capabilities. Since the sports version is our newer product, we were able to change the build, which offers better heat insulation. Additionally, the opening of the sports bottle is smaller, which also contributes to less heat escape.

The second difference is in the design. The stainless steel water bottle is somewhat wider, or "bulkier". It features a wood detail on the lid and comes with a carabiner attachment. That lets you hang your bottle on your backpack. The sports water bottle is designed much slimmer, thus fitting into all standard bicycle holders and daypacks.

Does the thermal coating come into contact with the contents or me?

Neither on the outside, which you touch, nor on the inside of the bottle, is there any coating. The material used is so high-quality that no coating is needed. Our thermal coating sits on the outer wall of the inner body, where it minimizes heat radiation. It is a copper layer. Both the drink and you only come into contact with food-safe 18/8 (304) stainless steel, not the coating.

Is this bottle completely plastic-free?

Yes. This bottle is completely plastic-free, lid included. Your water touches nothing but steel. The inside is uncoated 18/8 (304) stainless steel.

Is it tested for lead?

Independently tested for lead under the US CPSIA, and we retest every year. The current report is on our certificates page. Free to download, no form.

Is this water bottle non-toxic?

BPA-free and toxin-free where it is tested: your drink touches nothing but uncoated 18/8 steel. No liner, no coating, no plastic, not even in the lid. The lab reports are on our certificates page. We retest every year.

Can I have my product personalized?

Certainly, customization through laser engraving is available for this bottle. This is not temporary; your engraving is permanent. You can preview what your engraving will look like before you order. Please note that engraved items cannot be returned.

Is this bottle BPA-free?

Yes. There is no plastic in this bottle at all, so there is no BPA in it either. The seals are made from food-safe silicone. Our lab reports for this bottle, including the lead test, are on our certificates page.

Which of your products are thermally insulated?

Our thermally insulated products include our two water bottles and our insulated food jar. Our typical lunch box is not thermally insulated.

Are Blockhütte water bottles leak-proof?

Yes. The seal holds, even with carbonated drinks. It prevents spills during travel, sports, or daily use.

How long does an insulated water bottle keep water cold?

Ours keeps drinks cold for 25 hours and hot for 13 hours, with no preheating. You get the most out of it if you rinse the bottle with cold water first. Then fill it right to the top.

Can I put hot drinks in this bottle?

Yes. It keeps drinks hot for 13 hours, with no preheating. Rinse it hot and fill it to the top, then keep it closed.

Can I use the bottle for sparkling water or soda?

Yes, our bottles are pressure-resistant and safe for carbonated beverages.

Is the bottle dishwasher safe?

Yes: bottle, cap and seal all go in the dishwasher. The wide-mouth opening makes cleaning easy.

What material is the bottle made of?

18/8 (304) food-grade stainless steel, uncoated inside. Your water touches nothing but steel, and the steel does not hold on to yesterday’s smell.

What sizes are available?

Three sizes: 17 oz, 25 oz and 34 oz.

Through our extensive travels in the past, it became even more important to us, for environmental and cost reasons, to always have something to eat and drink on hand. We opted for stainless steel lunch boxes and water bottles. However, these products were of inferior quality: either they were made of cheap stainless steel, were not food-safe, or they leaked. This set our goal: to bring the best lunch box to the market in terms of sustainability, quality, and value for money.

Our stainless steel thermos bottle is thoughtfully designed, featuring improvements such as an extended cap, a modified closure, and a shift from a hollow seal to a solid material seal. Feedback from our community indicates that it's the small details that make a difference in our stainless steel water bottles. No more worrying about a soaked backpack due to a leaking old water bottle.

The 17oz stainless steel water bottle is perfect for thirsty kids at school. The 25oz stainless steel water bottle is ideal for long days at university or a well-deserved lunch break at work. The 34oz stainless steel water bottle is perfect for a marathon of lectures at university, long training days, or a relaxed weekend hike.

For all drinks, wether carbonated or not

Self-praise is no praise. That's why we rely on the independent statements of comparison platforms like www.Vergleichen.org, where our stainless steel bottle was rated very highly. This is due to our unbeatable quality and our excellent customer service. Also, the useful additions that you receive with your stainless steel drinking bottle, such as the sustainable coconut brush, the transport bag, or the replacement seal, are well received. We are convinced of our quality and therefore offer a 3-year warranty on all stainless steel thermo drinking bottles, whether 17oz, 25oz and 34oz.

Blockhuette has the ferst climate neutral water bottle made from stainless steel

We believe that if we all consume more consciously, our environment can recover from the high burden in the long run. That's why we want to provide you with extremely easy-to-use and unbeatably high-quality products as a first step. So that in the second step, it becomes effortless for you to avoid single-use products, such as plastic sandwich bags and plastic bottles. With sustainable everyday products and a conscious decision, we can reduce our plastic consumption from an average of 40 kg per year by up to 6 kg! But that's not enough for us! We want to take responsibility for reducing the emissions that we as a startup generate with our products and, if they cannot be reduced directly, to offset them in the first step. For the double-walled water bottles, we have chosen a project that helps to provide clean drinking water in India, more precisely in Odisha, with the help of new sterilization possibilities to neutralize germs and impurities in the water.
