7 of the Best Stainless Steel Water Bottles: Reviews and Comparison

Without a doubt, the Hydro Flask Standard Mouth is our pick as the best stainless steel water bottle. It isn’t the cheapest but this bottle will provide excellent insulation and durability that will last for years.

Very close at second is the Klean Kanteen Classic that possesses the combination of quality, ergonomics and insulation that you want from a water bottle. You can’t go wrong with any of these two brands – it will just be a matter of preference.

Best Stainless Steel Water Bottle

According to Medical Daily, around 75% of the American Population is chronically dehydrated.

The fact is our body needs water.

Need proof?

Based on research, drinking water has many benefits to our body and we’ll look at 11 of them.

This should give you inspiration on the why.

Let’s now move on the how.

To ensure enough water consumption, you’ll need a water bottle that you can bring with you at work or in the gym, wherever you’re spending the day in to give you easy access to it.

In this article I will be focusing on stainless steel water bottles.

In my opinion these are some of the best options available because these provide great insulation and very durable.

These bottles are so durable that you can bring it with you literally anywhere without worrying about it breaking unlike glass bottles that can easily break.

We’ll be looking at some of the best options available right now.

Finish: powder coat
Volume: 12, 18, 21 or 24 ounces
Insulation time: up to 12 hours for hot liquids, up to 24 hours for cold liquids
BPA free: Yes

The Hydro Flash is one of the best stainless steel water bottles available to date thanks to its combination of quality, insulation and ergonomics.

With this bottle in tow, your cold drinks will stay cool for hours on end.

Daniel Zweier of Backpackers.com said that hot drink he put was only “slightly cooler” by the 12th hour.

Now if you’re actually drinking hot liquid expect it to cool down faster because it is exposed to air but with the lid fully sealed, it will stay hot.

In the same test, ice cubes stayed whole even after 30 hours which is pretty darn impressive.

And with the Flex cap on this is completely leak proof as proven in a number of tests done by sites like The Sweet Home.

Even with the sports cap on, it is almost sealed tight even with the small release valve present.

The release value will close shut when it’s fully shut so you don’t have to worry about your gym bag without leaving a puddle of water inside.

You can also drink water directly from the bottle if you so choose. The metal edge is tapered with a round lip so it’ll be like drinking from a glass bottle – very cool.

The narrow 1-3/4″ opening helps with insulation but still wide enough to fit ice.

At the exterior, the Hydro Flask has a durable powder coat finish – perhaps the most durable finish you can have. Having this finish prevents the exterior from getting too hot if you leave this under the sun.

This bottle is available in several sizes – 12, 18, 21 and 24 ounce bottles.

Picking one again will be all about personal preference. If you’re a hydration junkie then buy the large 24 or 32 ounce bottle. But if that bottle is too big then the 21 ounce bottle is good compromise and will fit most vehicle cup holders.

Are there potential issues?

There aren’t many to be frank. You’ll find complaints about quality issues but that shouldn’t be an issue because Hydro Flask comes with a lifetime warranty for manufacturer defects. Even the cap is covered by this warranty. If it leaks, they will replace it for you.

The manufacturer recommends that you hand wash this bottle. Heat from the dishwasher can damage the insulated and powder coat finish.

Some consumers didn’t like that part of the drinking surface is exposed. If you look inside the bottle, the thread that holds the cap is on the inside part of the lid. This is by design as sipping on a threaded surface isn’t comfortable.

Runner Up: Klean Kanteen Classic

Finish: powder coat
Volume: 12, 20, 32 or 64 ounces
Insulation time: up to 24 hours for hot liquids, up to 90 hours for cold liquid
BPA free: Yes
Warranty: Lifetime
Body material: 18/8 food grade stainless steel
Dishwasher safe: No

Klean Kanteen has been known to manufacture great quality water bottles for years.

Here’s another option that comes with a lifetime guarantee.

If you’re looking for something bigger like bigger than the 24 ounce bottle that Hydro Flash offers, this is a good option.

The manufacturer claims that drinks will stay cold for up to 90 hours and hot for up to 24 hours!

Consumers agree with these claims and love it for its great insulation properties.

If you’re a big coffee drinking and love to bring coffee to work, this bottle will do a good job at keeping it hot! It certainly beats having to drop by Starbucks and spend $5 to $10 for your caffeine fix.

Finish varies and would depend on variant you’ll choose. They have glossy and matte powder coat finishes and the plain stainless steel finish minus the powder coat.

For me personally, I’d go with the powder coat finish because it is much more durable and insulates hot liquid better. The powder coat also prevents the bottle from sweating if you put cold liquid.

Klean Kanteen is one of the most durable bottles according to Brian Wu of Your Best Digs as it only had minimal dings after their drop test. It does come with a manufacturer’s “Strong As Steel” guarantee so this gives you peace of mind that this bottle will be able to handle outdoor abuse.

In fact a lot of campers and outdoors people use this and gave rave reviews.

The loop cap is solidly designed and will prevent leaks. Just make sure to seal it tight. I like this design because you can easily clip this on your bag or luggage.

Some potential issues

Biggest issue with this water bottle would be size. This will not fit in any cup holder inside your vehicle. You can opt for the narrower Klean Kanteen Wide Insulated 20 ounce bottle with both the brushed stainless and powder coat finish.

Heavy Duty: YETI Ramber 26 ounce

Finish: powder coated or brushed stainless steel
Volume: 26 ounces
Insulation time: not specified
BPA free: Yes
Warranty: Lifetime
Body material: 18/8 kitchen grade stainless steel
Dishwasher safe: Yes

One word to describe the YETI Rambler water bottle is sturdy.

This is the water bottle to have if you’re an outdoorsman who loves to hunt.

Their water bottles are made with 18/8 kitchen grade stainless steel.

YETI says that their bottles aren’t line with any plastic whatsoever so you can use their bottles for coffee and it wouldn’t leave any aftertaste if you put in water afterwards.

If you look at their website, their motto is “BUILT for the WILD” which says a lot to their commitment to quality.

Outdoorsmen like Sean McCoy of GearJunkie have torture tested this bottle and say that this bottle will keep drinks hot for 4 hours even in freezing temperature.

He also drop tested this (6 feet) on both sides and it only had little damage.

The leak-proof cap is also heavy duty and has a 3-finger grip making it easier to carry.

You can also wash this inside a dishwasher. This is the only one in this list that’s dishwasher safe.

Possible issues

There isn’t much in terms of quality and insulation. But if you want to nitpick, this water bottle isn’t as good as the Hydro Flask at keeping drinks hot. It also lacks accessories and design options.

Travel Buddy: Coldest Water Bottle Travel Mug

Finish: powder coated
Volume: 21 ounces
Insulation time: up to 36 hours for cold liquids
BPA free: Yes
Warranty: Lifetime
Body material: 18/8 stainless steel
Dishwasher safe: No

Summer here in our country is a nightmare with temperatures rising up to as high as 40-ish degrees Celsius.

Normal water bottles would not stand a chance against this heat. Leaving your water bottle in the car in the middle of summer? Forget about it, when you come back it’ll be warm.

The Coldest Water Bottle is a good option to beat the summer heat. This water bottle uses a high grade 18/8 stainless steel that they claim will keep drinks cold for up to 36 hours!

Now that figure isn’t a guarantee because there will be a lot of variables like outside temperature, humidity and if often open the bottle for a drink.

Do you like to swim? The manufacturer also claims that this bottle will float even if it’s full. So this bottle can double as a toy for your kids.

This 21 ounce bottle is slim enough to fit in most cup holders (99% to exact).

The powder coat finish prevents it from sweating.

At the bottom of the bottle is a rubber grip that prevents slippage. The standard version comes with a leak free cap with a loop that makes it easy to carry or clip on your bag.

Optional accessories are available like the sports straw cap for folks who work out a lot.

Workout Buddy: Takeya Originals Vacuum-Insulated

Finish: Powder coated
Volume: 14, 18, 24, 32 or 40 ounces
Insulation time: 12 hours for hot liquid, 28 hours for cold liquid
BPA free: Yes
Warranty: Lifetime
Body material: 18/8 grade stainless steel
Dishwasher safe: Only the lid

Gym buffs who frequent the gym know that hydration is important to maximize their performance.

What better way to hydrate than with a water bottle that will keep your drinks cold for up to 28 hours!

What makes the Takeya Originals a great option is the spout lid that makes it easy to drink.

You don’t need to remove the whole lid just for a sip of water.

The spout lid is great for workout buffs because sweaty hands can make it tough to open a tight lid.

Just lift up the lid then drink. You don’t need to touch the spout.

It also comes with a sturdy carry-on clip that makes it easy to carry.

Remove the cap and the opening is wide enough to put ice in and load water in without spilling from a refrigerator dispenser.

Consumers love it because it kept water cool for hours on end. Takeya claims that liquids will stay cold for as long as 28 hours and hot for 12 hours.

They back up their claim with a lifetime warranty so don’t worry about reviews that say this water bottle has poor quality. Takeya will replace the bottle for you if there are manufacturing defects.

These bottles are available in a variety of sizes from the small 14 ounce all the way up to 40 ounces. So these bottles will be great for kids to water guzzling adults.

Perhaps a bigger reason why this is so popular is the lid. The narrow spout makes it easier to drink off.

And even if drinks don’t stay cool longer as the Hydro Flask, it’s okay with them because this bottle is cheaper.

The lid will seal off liquid and prevent it from dripping.

Another con would be the diameter. This will not fit in standard cup holders inside your vehicle.

For the Multi-Tasker: Contigo Autoseal Chill

Finish: un-painted stainless steel finish
Volume: 24 ounces
Insulation time: 28 hours for cold liquid
BPA free: Yes
Warranty: Lifetime
Body material: stainless steel (Contigo does not specify what grade they use)
Where to buy? Check the Latest Deal in Amazon

The first two options (Hydro Flask and Klean Kanteen) in this list have caps that you have to remove to drink water.

Contigo is the first option here that has an AUTOSEAL lid that easily opens with a push of a button.

When you release the button, it closes automatically. The whole mechanism is made from plastic so there’s risk of it deforming if you put in boiling water.

This is a big reason why my wife wouldn’t trade her Contigo water bottle even for a more expensive Hydra Flask.

She had a Contigo bottle while she was down with the flu and drinks water on the bed without it spilling. That’s how good their lids are. And the AUTOSEAL Chill will give you the same type of convenience.

It also comes with a carry on strap that makes it easy to carry.

Only the lid is dishwasher safe while the body is not.

This bottle has a double wall design but it does not have a powder coat finish. If you put in a cold drink on a hot day, there will be some risk of it sweating because of this.

The double wall structure will help keep drinks cold or hot for hours.

But Contigo’s thermal retaining capabilities will not be as good as other brands like Hydro Flask, Klean Kanteen or Takeya.

Potential issues

One concern for me would be the durability of the lid because it has a lot of moving parts. But Contigo does back this product up with a lifetime warranty so this puts some peace of mind.

Compact: MIRA Cascade

Finish: powder coat
Volume: 12, 17 or 25 ounces
Insulation time: 12 hours for hot liquids, 24 hours for cold liquid
BPA free: Yes
Warranty: 1 year
Body material: 18/8 stainless steel
Where to buy? Check the Latest Deal in Amazon

When it comes to popularity, the MIRA is up there with the Hydro Flask Classic with over 3,000 reviews.

It’s not surprising as MIRA is one of the cheapest options out there – their 25 ounce water bottle will cost under $25!

If you opt for the pattern prints, the price will obviously go up. But take note that these bottles will not have the powder coat finish.

Regardless, the fancy design is what makes this bottle popular. For the Cascade bottle, you’ll have more than 20 design options!

Take note that if you do not get the plain colored bottle that has the powder coat finish, expect this bottle to sweat if you put in cold water.

Consumers say that this bottle is pretty durable. One mom in particular said that their MIRA bottles have been dropped multiple times and it didn’t dent or scratch. But you’ll have to get the powder coated option because it adds that extra layer of protection.

If you’re the type that fancies these colorful patterns, this is the water bottle for you.

MIRA bottles are compact and will fit inside a backpack. The narrow diameter bottle will also fit in most cup holders.

Ice may not also fit in the narrow opening. The one big advantage that a small-cap design has is its ability to keep cold liquids cold for longer periods. MIRA says will stay cold for up to 24 hours.

Some potential issues

Biggest would be the warranty. Unlike the Hydro Flask and Klean Kanteen that come with lifetime warranties, this brand only comes with a one year warranty.

How to choose a stainless steel water bottle?

There are literally hundreds if not thousands of stainless steel water bottles in Amazon. These vary in size, design and quality of metal used.

To help you narrow down you options here are the some of the features you need to look at.

1. Capacity

This perhaps is the most important. Where do will you use this water bottle? Are you bringing this to the gym or at work?

Striking the balance between capacity and size is a delicate balance. Bottles of varying sizes are available from 18 all the way up to 64 ounces.

Remember that the larger the water bottle the heavier it becomes and more cumbersome.

Ask yourself where are you storing the bottle when you bring it and how much do you drink. Lastly, if you have access to drinking water in your workplace, a smaller bottle may be enough.

2. Quality

One way to look at this is by check the reviews. Do consumers like the quality? Does it have one common issue that multiple reviews complain about?

Also check reviews if there are issues with leaking and such.

Go with a water bottle with a powder coated exterior as these tend to be a lot more durable and less prone to chipping. Avoid bottles that have painted coatings as these will scratch easily and won’t last as long.

3. Reviews

You can easily spot good quality bottles with reviews. A really good product will have thousands of reviews with high ratings. It’s pretty hard to achieve this by using fake reviews. This will surely trigger bells that Amazon has set in place to fight such.

4. Type of lid

There are different types of lids available. Choosing between any of these lids will be a matter of personal preference and where you’ll use this the most.

Flex cap – This is just a fancy term that manufacturers use to describe a bottle cap. The top brands have holders that make it easy to carry with you.

Straw – A great feature to have if you want something where you can easily sip water from.

Sports cap – Similar to the straw type lid, this gives you easy access to drinking water without having to open the lid.

Press in lid – Great option if you use your water bottle to drink hot beverages like coffee or tea. The small opening means you’ll not burn your tongue sipping hot liquid.

5. Insulated or non-insulated

There are two types of containers that manufacturers use – double walled insulated and single wall, non-insulated. The former is better at keeping liquid hot or cold for longer periods while the latter does not. Of course you’ll have to pay an additional premium to get this feature.

6. Stainless steel quality

Look for water bottles with the highest quality stainless steel which is the 18/8 food grade. Anything less would be a waste of money in my opinion.

How to care for and maintain stainless steel water bottles?

Caring for stainless steel bottles is simple. You can most type of drinkable liquid in it from juice, coffee, water, etc. but please avoid putting anything in it that has chlorine in it because it will eat through the stainless steel layer and eventually corrode it.

These bottles are pretty sturdy even in the harshest conditions. As times goes by, gunk will build up especially on the cap area.

To make it last as long as possible, you’ll have to clean it from time to time with a brush plus your favorite cleaning agent. You can use dishwashing soap but if you’re concerned for the environment – vinegar and baking soda will suffice.

One of the best brushes to clean any bottle would be the OXO Good Grips water bottle brush. It’s a combination of a large brush for cleaning the body and smaller brushes for cleaning nooks and crannies.
