When you are in the gym, you should use the best gym water bottles to store your water, as opposed to carrying it around in a glass or your favourite mug. Why? Gym water bottles are designed to perform well in an environment where things aren't being handled gently, to say the least.
Also, using the communal water fountains in gyms was always a risky business, let alone in post-pandemic times. FYI, you should drink around half a litre of water an hour before you hit the gym and drink continuously when you are there, at least around quarter of a litre for each 15 minutes you spend in the church of iron working on those guns, to make sure your body is appropriately hydrated.
If you attend cardio classes, you'll need even more water. You want to lose fat, not water, so make sure you drink a lot when you're in a closed space sweating a lot.
What else might you need if you want to build muscle and gain weight? Protein, of course! Have a look at our best protein powder and best weight gainer guides to learn more about the dos and don'ts and sneak a protein bar in your gym bag too to make sure when hunger strikes, you'll have the right snack at hand.
Best gym water bottles, in order of preference
Who doesn't like a stainless steel water bottle? The Rockay Water Bottle is not just any stainless steel water bottle either: it is insulated as well as being environmentally-friendly. Rockay claims that it removes 714g (77 bottles) of plastic waste from the ocean for every bottle purchased.
Bottle body is made from recycled stainless steel, the packaging is made from 100% recycled cardboard and the screw-top lid is also made made from recycled plastic. Rockay even encourages people to upcycle the packaging and use the tube the bottle came in as pen or utensil holder while the little information card can be re-used as a bookmark.
As well as being super green, the Rockay Water bottle is also highly functional: the screw-top lid provides a leak proof seal so your gym clothes won't get drenched in the bag and thanks to the insulated walls of the bottle, liquid in the bottle will be kept cold for 24 hours and hot for 12 hours.
The wider mouth hole makes it easy to drink from the bottle and to clean it more efficiently, which is gandy as the Rockay Water Bottle is not dishwasher safe. For the same reason, if you are planning on using it as water bottle, I'd recommend not putting anything else but water in it as dried milk etc. might be a bit more challenging to remove later.
Understandably, the Rockay Water Bottle is more expensive than its plastic counterparts but it will also last for longer and will keep your drinks cool more efficiently, too. If you prefer ice-cold water in the gym as opposed to the lukewarm variety, invest your money wisely in the Roclay Water Bottle.
The BFA 750ml Mobility Water Bottle is a sort of accessory that makes you slap your forehead and think: "why have nobody thought of this before?" What makes this a mobility water bottle? Just have another look: the ribbed outer shell practically transforms this water bottle into a foam roller. Yeah, you read that right.
This is a crazy idea, we agree. But if you think about it, the concept of the BFA 750ml Mobility Water Bottle is also genius. The shape of this water bottle is perfect for rolling smaller areas like the calves or even the lats, but it can also help relieve tension in the front of the quads, using your hands to apply pressure (as opposed to the bottle resting on the floor and you are rolling on it).
The 750ml capacity is plenty big enough for most workouts and the integrated straw makes sure you can retrieve every last drop of the liquid from the bottle. You can always just unscrew the top of the bottle and drink without the straw, too. The BFA 750ml Mobility Water Bottle has a narrow neck so it is a bit fiddly to clean it but as long as you only drink water from it and air dry it when not in use, it should be okay not to wash it every day, given it's made of stainless steel.
The Sistema Traverse Tritan is the ideal sized gym water bottle: 850 ml should be enough for a 45-50 minute session and if you are not in the gym to socialise, that should be more than enough time to do your workout efficiently.
The Traverse is made out of durable Tritan plastic which is also BPA and phthalate free. This stain and odour free bottle can be washed in the dishwasher and it is also freezer proof. you don't have to worry about water going everywhere in your gym bag either; the Traverse is absolutely leak proof.
Although it comes in a variety of colours, like blue, green, red, purple, black and white/clear, you can't pick which one you'd like when you order it off Amazon.
Great value for money and surely a sturdy companion in the gym.
The Ion8 slim water bottle is the smallest in volume on our best gym water bottle list, being only 500 ml (there is a 750 ml version, too). This bottle comes in 15 (!) colours so you can colour-coordinate it with your gym tights and vest.
As the sticker advertises on the side of the bottle, the Ion8 is leak proof, until you lose the little rubber stopper that goes over the mouthpiece in the lid. it is not easy but definitely not impossible to lose it and once it's gone, so is leak proof-ness.
But if you are careful enough, the Ion8 repays you with a great lid-locking system which can be opened with one finger yet secures the lid on tightly.
The Ion8 is also suitable for hot drinks but it won't replace your hot water flask.
The Sundried water bottle is a bit on a swag side and probably you won't look overly manly drinking from it, not like it matters in a commercial gym where no one really looks at each other in the first place.
On the upside, it can hold enough water for a 45-minute session and thanks to the larger base, it's also harder to knock over. The silicone mouthpiece and the screw-on lid makes it leak proof too.
Talking about the silicone stopper: it has a fairly strong smell to it straight out of the box which can be distracting to some people. Just soak it in hot (but not boiling) water for a good 10 minutes and it should doctor the issue.
Being toxin-free and ethical, one could say that the Sundried gym water bottle is also millennial-safe.
As much as you won't need piping-hot drinks in the gym, it might come handy to enjoy some ice-cold water during workouts when the temperatures are soaring high, as they did in July. The Takeya Actives can keep drinks cold for up to 24 hours, which is plenty, even if your gym is an hour drive away.
Even more so, the lid is insulted and leak proof too. The Takeya Actives is pretty well-rated on Amazon, which proves its quality. Many insulated containers tend to receive lower ratings due to their build quality (sweating, insulation issues, etc), but not the Takeya.
For added piece of mind, this water bottle comes with a limited lifetime warranty. The plastic carry ring on the top is just the icing on the cake, really.
All this comes at a price, though. The Takeya Actives is the most expensive gym water bottle on the list, the 950 ml version selling for around £25. On the upside, this water bottle can actually replace your hot water flask. Two-for-one.
Although it is advertised as leak proof, the Sistema Hydrate Tritan Swift is probably not the best sealed gym water bottle out there. It is a good size, though, as well as being dishwasher, microwave (without lid), fridge and freezer safe.
This impact resistant gym water bottle is made out of clear non-toxic Tritan plastic and comes with a handy little finger loop. it is also odour free.
A good quality Sistema product, what can we say, does what it says in the box. Nothing less, nothing more.
This is not a gym water bottle bottle you can shove in a bumbag but in return, using Pro Series is probably the easiest way to hit your recommended daily water intake goal. It can hold over two litres of liquid so just fill it up in the morning and if it's empty by the time you go to bed, you drank enough water for the day.
As mentioned at the beginning, it is not recommended to mix anything with water in this gym water bottle, given the small mouth on the top. It is practically impossible to scrub the insides, so if you have dried protein powder bits stuck to the area close to the lid, it might take a while to have them cleaned.
The Bulk Powders Pro Series water bottle has a stainless steel screw-on cap, ergonomic handle and a nylon carrying loop, making it easy to drink form it and to carry it around. When it's full, it doubles up as a 2 kg dumbbell so you can superset your water intake sessions with bicep curls. Perfect.
What is a gym water bottle?
What makes a reusable water bottle a gym water bottle?
Gym water bottles need to be a bit sturdier because they are more likely to be kicked around or knocked over in the gym. It is also beneficial for it to be larger in volume; you will spend at least 30 minutes in the gym for each session so you will need to drink at least 500ml of water while you are there.
It is also worth mentioning that the below gym water bottles are water bottles and not shakers. Although some of them have the benefit of a larger opening on the top, it is probably for the best to keep these for water only to avoid any bad taste or floating bits in your water.
