New Insulated Metal Water Bottle from the UK Brand – Wave

Best reusable water bottle UK by Wave

Material: Stainless Steel | Insulated: Yes | Top: Screw Top | Sizes available (ml): 600

This insulated bottle is the only one on this list that is offered by a British company. Not only is it eco-friendly, but quite a stylish water bottle in a rich navy blue colour. So, if you want to support a local human-sized company with a great team, this eco-friendly water bottle is the one!

Being BPS-free, BPA-free, and insulated, the Wave bottle will keep your drink clean and cold for up to 24h or warm for up to 12h. Great for long trips and picnics. 

At the moment, their stainless-steel bottle is only available in 600ml and in one colour, but I find it to be the ideal size for a water bottle when I am on the move. And the blue is just gorgeous…

Their biodegradable phone case is one of my favourite eco-friendly products from Wave, and I’m sure their new water bottle will be as well. I also really appreciate that the bottle is shipped in a 100% recyclable plastic-free bag made from a sugar cane byproduct.

This shows me that the company cares not only about delivering high-quality and non-plastic water bottles, but they ensure the whole purchasing journey is up to the highest standard and doesn’t harm the environment.

Good Stuff
* Local UK company
* Insulated for cold British days
* Easy to clean
* Eco-friendly packaging
* I love this blue!

Bad Stuff
* Only comes in one size
* If you don’t like blue…
* Not dishwasher friendly

Best Reusable Water Bottle for Switching Flavours – 24Bottles

Reusable drinking bottles by 24Bottles

Material: Stainless Steel | Insulated: Yes | Top: Screw Top | Sizes available (ml): 330, 500, 850

Stainless-steel bottles are great, they are durable and less heavy than glass. But they have a major flaw: they are not dishwasher friendly, and washing them by hand is a real pain in the neck… especially when you’ve had fruit slices or strong tea lingering in the bottle all week!

24Bottles’ Clima Bottle is a stainless-steel, screw-top bottle in three sizes that’s both double-walled and insulated. The best thing, in my opinion, is that the inside of the bottle won’t retain flavours. That means after you’ve washed out that old lemon water, Fanta, or iced tea, your next bottle of water won’t taste funny!

If you need an insulated water bottle and you are planning to switch things up with different flavours in your stainless-steel bottle, 24Bottles is the way to go!

Good Stuff
* Easy to clean
* Insulated, so stays warm in winter
* Wide mouth for ice cubes
* Grippy sweat-free material
* Great colourful designs

Bad Stuff
* Can get dirty on the outside
* Not dishwasher friendly
* On the pricey side
* Steel lid is hard to grip
* Dispatched from Italy (customs may apply after Brexit)

Overall Best Stainless-Steel Water Bottle – Hydro Flask

Reusable drink bottle by Hydro Flask

Material: Stainless steel | Insulated: Yes | Top: Screw Top | Sizes available (ml): 350, 530, 620, 710

As for many products, the perfect bottle doesn’t exist, and you will have to compromise. But if you want an all-purpose bottle and can’t decide on what to compromise (e.g., insulated vs lightweight), then you should look closer at Hydro Flask. Their bottles have a lot to offer; they do a great job, but without being the best in any aspect.

As an example, they are insulated but won’t keep your drink warm as long as some competitors. But in counterpart, they will be lighter than these competitors.

Hydro Flask also offers many lids and caps to adapt to the situation.

If you are looking for a single reusable bottle to use at home, at the gym, at the office or during your trekking, look no further, Hydro Flask bottles may be your best option!

Good Stuff
* Keeps your drink cold for 24h
* Very easy to open (rubber lid)
* Leak proof
* Mouth wide enough for ice cubes
* Convenient handle
* Many caps and lids to buy
* Comes in many colours

Bad Stuff
* Not the best insulation (hot up to 6h)
* Most expensive option from this list
* Not dishwasher friendly

Best Fashionable Reusable Water Bottle – Chilly’s

Fashionable metal drinking bottle by Chilly's

Material: Stainless Steel | Insulated: Yes | Top: Screw Top | Sizes available (ml): 260, 500, 750

“Reusable bottles have no style.” If you agree with that, you haven’t seen Chilly’s bottles yet! Their sophisticated and unique patterns make the brand stand out from the other competitors.

These bottles are just gorgeous, and their unique designs transform a simple eco-friendly bottle into a fashionable item!

And Chilly water bottles are not just pretty… their screw top is leakproof, and the double wall vacuum technology will keep your drink cold for up to 24 hours or warm up to 12 hours.

Best Insulated Water Bottle – Sho

Insulated non-plastic water bottle by Sho

Material: Stainless Steel | Insulated: Yes | Top: Screw Top | Sizes available (ml): 260, 350, 500, 750, 1000

It’s not so often that I can say a product works better than advertised… Well, Sho’s bottles are one of them. If you are looking for an insulated reusable bottle that will keep your drink cold/warm through the day (and more, according to many reviews), then you should consider Sho.

They may not be the sexiest bottles on the list, but they are incredibly efficient, leakproof, and durable! Not convinced yet? Maybe their lifetime guarantee will tip the scales…

Looking for a large reusable water bottle? They come in many sizes, including a huge 1L version, for those with a great thirst…

* Comes in different sizes
* Nice choice of colours

Bad Stuff
* Not dishwasher friendly
* Bottle is strong, but paint is fragile

Best Glass Water Bottle – Purifyou

Refillable water bottles for hot and cold drinks by Purifyou

Material: Premium glass | Insulated: No | Top: Screw Top | Sizes available (ml): 360, 650, 1000

Purifyou is the only BPA-free eco-friendly glass water bottle on the list because glass reusable bottles tend to be less versatile as they are too fragile and heavy for a “nomad” life. However, they are dishwasher friendly, and if you consider that it’s an important point for a reusable bottle, you may feel let down with all the stainless-steel options.

Purifyou’s bottles are obviously not insulated, but they can go in the microwave or in the fridge, which is also a non-neglectable advantage of glass bottles.

The brand is also doing its best to make its products less fragile: the bottle is made of high-quality glass and comes with a resistant silicone sleeve. I still don’t recommend dropping it on the floor, though…

If you are looking for a bottle for your next adventure, glass water bottles may not be the best option. But if you have a rather sedentary use of the bottle (at the office or at home), it is a great alternative to plastic bottles. 

Purifyou’s bottles are dishwasher friendly, you can warm them in the microwave, and they don’t give any taste to the water (unlike some stainless steel or plastic bottles).

Tip: Being dishwasher friendly, they also make great reusable juice bottles.

Good Stuff
* Heat-resistant glass
* Resistant, yet lightweight (for a glass bottle)
* Silicone sleeve for extra protection and non-slip grip
* No influence on the taste of the water
* Leak proof
* Easy to carry thanks to the lid
* Microwave and dishwasher safe

Bad Stuff
* Doesn’t keep your drink cold/warm as long as insulated bottles
* Resistant, yet still more fragile than stainless steel

Best Foldable Water Bottle – Nomader

Foldable reusable drinks bottle by Nomader

Material: BPA-Free Silicone | Insulated: No | Top: Screw Top | Sizes available (ml): 650

Stylish… cute… insulated… but what if convenience is your main and only concern? No worry, I have you covered as well!

Forget insulated and glass bottles – these are too heavy and take up so much space inside your ultra-light backpack. What you need is the eco-friendly silicone collapsible water bottle from Nomader! It’s a great safe water bottle that will fit into any small pocket, right next to your snacks, glasses case, and a book, among other essentials you keep with you at all costs. 

That sports water bottle is designed for the adventurer that needs a convenient, lightweight and efficient reusable bottle. Nothing else.

With a capacity of 650ml, you should have enough water until the next refill point. More capacity would start to bother you anyway. The bottle comes with a big strap, so you can easily carry it around your wrist. And once you’re finished, you can just fold the bottle and throw it in your bag or carry it in your hand if you use it as a running water bottle. How convenient is that?

Moreover, once you’re back at home, you won’t have to swear while trying to reach the inside corners of the bottle with a cleaning brush, as it’s dishwasher safe!

Who said stainless steel bottles are always heavy? Klean Kanteen’s Outdoor Classic Water Bottle is here to prove them wrong! With only 180g, it’s not only the lightest stainless-steel bottle but also the lightest bottle on my list! (Yes, even lighter than Nomader’s bottle, but the Klean Kanteen’s one doesn’t fold!)

With such a lightweight and as stated in their name, Klean Kanteen’s bottles are mostly designed for outdoor use. Moreover, their sport mouthpiece makes it easier to drink on the go and reduces spilling (try to drink out of a wide-mouth bottle while running, and you will understand the value of the sport cap). The size of the bottles also makes them a good fit inside your bike bottle cage!

Most Asked Questions

What is the best alternative to plastic water bottles?

Reusable water bottles are the best single-use plastic water bottle. You can choose either a stainless-steel water bottle from the list above or an eco-friendly glass water bottle. They are both environmentally friendly and have their own advantages, so it’s really up to your preference.

Stainless steel keeps all the drinks cold or hot a bit longer than glass. Glass bottles are a little bit fragile but keep your drinks tasting good. They are also infinitely recyclable and maintain their quality every time they are remade.

Boxed Water is another kind of eco-friendly water bottle that is growing in popularity. These bottles can be a great alternative to plastic bottles as they are 100% recyclable, and 76% of the box is made using paper from certified, sustainably managed forests.

Are metal water bottles bad for the environment?

No, metal water bottles are not bad for the environment; however, not all metal bottles are good for the environment. Some of these bottles may contain aluminium and other harmful chemicals that can cause some serious health issues.

Therefore, you should choose a reusable water bottle made of made with #304 or 18/8 food-grade stainless steel to make sure it is safe for your health and for the environment. 
– 18/8 means that it contains 18% chromium and 8% nickel. 

Stainless steel water bottles are good for the environment because they are reusable and can be used for a long period of time, but most importantly, they can be recycled once it reaches the end of their life.

How often should I clean my water bottle?

It depends on the water bottle and what you’ve used it for! If you’re only filling a stainless-steel bottle with pure, fresh water, you can just rinse it at the end of the day and clean it at the end of the week. 

If you’ve got a reusable plastic water bottle that holds onto flavours/aromas, or you’re filling a steel water bottle with squash, juice, tea, or other flavoured beverages, you should wash it after every use. This will stop flavour contamination.


Any one of my best reusable water bottles would be an ideal eco-friendly gift for your loved ones. Find more original ideas for ethical gifts in my eco-friendly gifts guide.
