🧊[Steel body, plastic lid]: Your stainless steel drinking bottle, a double insulated water bottle, travels protected in the durable 100% cotton bag. The screw lid is recycled plastic, because it has to seal, grip and survive being dropped. The bottle body and the threads are steel.

🧊[25 hrs. cold & 13 hrs. hot]: A copper layer between the walls of your insulated thermo bottle slows the heat exchange. Drinks stay cold for 25 hours and hot for 13 hours, with no preheating. The 18/8 (304) stainless steel is rustproof, inside and out. That makes it an ideal travel flask.

🧊[Leak-proof]: The precise thread and the solid material seal hold your metal water bottle shut, carbonated drinks included. A spare seal is in the box, and every wearing part is sold separately.

🧊[Very easy to clean]: The included natural bristle brush reaches the bottom of your stainless steel water bottle. Every part is dishwasher safe: bottle, lid and seal.

🧊[Test for 60 days]: If the Blockhütte vacuum flask is not for you, send it back within 60 days, no questions asked. Unused and in its original packaging. We refund the full price, and the return label is on us. Backed by a 3-year limited warranty.

How do your two water bottles differ?
Mostly in shape. This one is slimmer and fits standard bicycle holders and daypacks. The Vacuum Insulated bottle is wider, with a wood detail and a carabiner loop. Both hold 25 hours cold and 13 hours hot.

Does the thermal coating touch my drink?
No. The copper layer sits on the outer wall of the inner body. Your drink touches nothing but uncoated 18/8 stainless steel.

Is the lid plastic?
The screw lid is recycled plastic, and deliberately so. It has to seal, grip and survive being dropped. The bottle body and the threads are steel.

Are Blockhütte water bottles leak-proof?
Yes, carbonated drinks included. The seal holds the bottle lying down in a bag. If a well-used bottle starts to weep, a fresh seal fixes it.

How long do drinks stay cold or hot?
25 hours cold and 13 hours hot, with no preheating.

Can I use the bottle for sparkling water or soda?
Yes. The bottles are pressure-resistant and safe for carbonated drinks.

Is the bottle dishwasher safe?
Yes, every part of it: bottle, cap and seal. The wide mouth makes cleaning easy.

What material is the bottle made of?
18/8 (304) food-grade stainless steel, uncoated inside. BPA-free and odor-resistant.

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. All seals are food-safe silicone, BPA-free.

Is this water bottle non-toxic?
BPA-free and toxin-free where it is tested: your drink touches nothing but uncoated 18/8 steel. The body has no liner and no coating on the inside. The lid is plastic, and it never touches the drink. The lab reports are on our certificates page. We retest every year.

What sizes are available?
12 oz, 17 oz, 25 oz and 34 oz.

Can I have it engraved?
Yes, on four of our products: the lunch box, both water bottles and the food jar. Express Engraving: order by 1 PM PT and we engrave it the same day. It happens in our own facility in CA. Engraved items cannot be returned, so check the spelling first.

We want to get your Blockhütte gear to you as fast as possible. Most orders are processed within 1 business day. We route every order through USPS, FedEx, or UPS — whichever delivers fastest at the best rate.

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.

Leak-proof, every day

The seal is cut from solid material and the thread runs longer. The lid closes clean, so your backpack stays dry.

Sealed on its side, in a backpack, all day.

Particularly Temperature-Stable

All our stainless steel water bottles are equipped with our unique thermal coating. This ensures that your favorite drink always has the perfect temperature, whether nice and warm or refreshingly cool.

Recyclable & Plastic-Free Packaging

Sustainability is a top priority for us! For packaging, we have opted for sustainable and recyclable cardboard. Even with the cardboard, we ensure that as little material as possible is used, to save resources.

Fast Shipping

Your order ships from within the US. Ground delivery takes 2 to 5 business days in the contiguous US.

Most orders are processed within one business day. Alaska, Hawaii and the US territories take 10 to 14 business days.

Every package goes out with USPS, FedEx or UPS, whichever gets it to you fastest.

Food-Safe & Taste-Neutral

Your drink touches nothing but steel. The inside is uncoated 18/8 stainless steel: no coating, no aftertaste.

The seals are food-grade silicone, BPA-free. Which lab report covers which product is on our certificates page. Free to download, no form.

Stainless steel water bottle 34oz, leak proof & sustainable

Your favorite beverages shouldn't be filled in bottles that impart a metallic taste or in plastic bottles that contain substances like BPA & BPS. With our thermal water bottles, you won't have this issue. We are always striving to develop the best products. 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.

Water bottles made from stainless steel for children and teenagers

We have the right size or bundle for everyone, regardless of age or purpose. This allows you to choose the size that best fits your needs and preferences. 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.
