Most people know the benefits of water but still struggle to get enough each day. Owning a durable, functional, and perhaps even fashionable water bottle is one way to help you remember to drink water.

The Institute of Medicine recommends 15.5 cups of fluid per day for men and 11.5 cups of fluid per day for women. This includes total fluid intake from foods and beverages, as well as plain water.

Stainless steel water bottles keep water cold for hours, are better for the environment than plastic, and aren’t prone to breaking like glass water bottles. For these reasons, many new stainless steel water bottles have popped up on the market over the past few years. Whether you are looking for a water bottle for work, the gym, or traveling, there is an option for you.

Here, the best stainless steel water bottles:

If you want a stainless steel water bottle that’s easy to drink out of, made for being on the go, and keeps water cold for 24 hours, look no further. The Takeya Originals stainless steel water bottle has all of this and more. Plus, it costs less than more popular brands. This water bottle keeps cold beverages cold for 24 hours and hot drinks hot for 12 hours with its double-walled vacuum insulation. It’s easy to add ice cubes with a wide mouth opening, but the leak-proof spout lid ensures you can sip without soaking your shirt. If you prefer, you can buy a lid with a straw instead of a spout.

The Takeya Originals bottle is available in 18, 24, 32, and 40 ounces, and each comes with a wide loop for carrying, so it’s easy to pick up one-handed at the gym or office. Their innovative Hinge-Lock keeps the spout lid locked back away from your face while drinking.

The Takeya Originals water bottle is made from premium food-grade 18/8 stainless steel, which refers to 18 percent chromium and 8 percent nickel. It doesn't leach chemicals or transfer flavors of whatever is in the bottle. The durable powder coating on the outside of the bottle is sweat-proof, making it easy to carry and ensuring no condensation. Choose from a variety of bright colors.

Best Overall, Runner-Up: YETI Rambler 18 oz Bottle with Chug Cap

Yeti is a well-known, well-loved stainless steel water bottle brand. Designed for durability, Yetis are great for hiking, camping, and kayaking but are also excellent for taking to the office. That’s because, in addition to keeping water ice-cold for over 12 hours, the Yeti Rambler also keeps hot beverages, like coffee, piping hot for hours. 

The outside of the bottle has a DuraCoat color that won’t chip or fade, and it’s sweat-proof, so you can pick it up one-handed for easy drinking on the go. The Yeti Rambler is made from the highest grade 18/8 stainless steel, and its double-wall vacuum insulation keeps it free from condensation. The chug cap makes it easy to sip without spilling, whether in the car, the mountains, or the office. Just don’t use the chug cap with hot beverages.

The Rambler holds 18 ounces, which isn’t as much as some other bottles, but it fits in most cup holders and has a sturdy handle on its leak-proof lid, making it easy to tote. It’s also dishwasher-safe.

Best Budget: Contigo AUTOSEAL Chill Stainless Steel Water Bottle

Contigo Autoseal Chill Stainless Steel Water Bottle

Simply press the Autoseal button to drink and press the flip back down over the spout cover when done.

Made for one-handed drinking, this water bottle is perfect for traveling or commuting between the office, gym, and home. However, do not fill it with hot beverages. This one is best for water alone and not your morning java.

The Contigo Autoseal bottle comes in 24 or 32 ounces and has a small loop handle for easy carrying. Its sleek design allows it to fit in cup holders or easily slide into your bag. The lid can go in the top rack of the dishwasher but wash the bottle by hand.

Best with Straw: Iron Flask 64 Oz Wide Mouth Water Bottle With Straw Lid

The Iron Flask Sports Water Bottle has the functionality of other stainless steel water bottles—keeping cold drinks cold for 24 hours and hot drinks hot for up to 12 hours—but it comes with a straw for simple sipping. In fact, it comes with three different lids: a straw lid, flip lid, and stainless steel lid. That’s a bonus of the Iron Flask if you’re deciding between comparable brands; other brands sell additional lids separately.

The Iron Flask was made for sports but ranging in six sizes from 14 to 64 ounces, it can just as easily be used as an everyday water bottle. The 14 to 22-ounce sizes fit in a cup holder, while the larger sizes do not.

Best Screw Top: S'well Stainless Steel Water Bottle

S’well bottles were designed to be your “hydration accessory.” The company made stainless steel cool with its bright, vibrant colors and sleek design. And let’s be honest, some people need the cuteness factor to keep water consumption up. Available in three sizes, 9-ounce, 17-ounce, and 25-ounce, the narrower, sleek design of S’well bottles makes them easy to carry to work or workouts, as well as fit into cup holders and bags.

Since the mouth isn’t wide, these bottles are easier to drink out of without spilling. But the downside is that big ice cubes won’t fit inside. S’well uses triple-layered vacuum insulation that keeps cold beverages cold for up to 36 hours and hot drinks hot for 18 hours. You’ll never feel temperature or condensation on the outside of the water bottle.

S’well bottles only come with a screw-top but once secured tightly, it is leak-proof. S’well bottles are BPA-free and made from food-grade stainless steel. They are hand-wash only.

What Our Editors Say

"Staying hydrated while being sustainable is a priority, no matter where my day takes me, which is what drew me to this 17-ounce S'well bottle. While the bottle's a bit heavy for leisure day trips, it doubles as a hand weight when hiking or taking recreational walks. I picked a vibrant coral color, "Birds of Paradise," which also increases nighttime visibility during evening walks. I also appreciate the fact that its narrowly-designed mouth minimizes spills, especially when taking sips during a car ride." — Tori Zhou, Associate Health Commerce Editor

What to Look for in Stainless Steel Water Bottles

Lid:

Depending on what you’ll be using the water bottle for, you may want a specific type of lid. For example, if you’re playing sports or at the gym, you’ll likely want a straw or spout so you can grab a quick sip.

A wide-mouth lid is nice if you want to add ice to your water bottle or will be pouring liquids from another container into the water bottle. Some wide mouth lids also come with interchangeable straw and spout lids. 

Size:

Water bottles range in size and can hold 12 ounces all the way to 84 ounces or more. A 64 to 84-ounce stainless steel water bottle is a great option if you're playing tennis or a sport where you might be in hot weather for several hours and want your water to remain cold. A 17 to 32-ounce water bottle is nice for everyday activities like going to work or the gym.

Since stainless steel works for hot and cold beverages alike, consider if you plan to put coffee or tea in your bottle. If so, you might want a bottle that’s closer to 17 to 32 ounces. Some bottles, like the S’well bottle, are more narrow, while others are wide. Many of the wide bottles do not fit in cup holders and are bulkier to tote around. If you plan to take the water bottle in the car, on a plane, on a bike ride, or on a hike, for example, a slender model will be better.

FAQs

How do you clean stainless steel water bottles?

Some stainless steel water bottles can go in the dishwasher, but others should be hand-washed, so check on the company website to see what they recommend. If hand washing, use dish soap and hot water, clean with a scrub brush, and air dry. Use a smaller scrub brush made for straws to clean straws, spouts, and lids. If you want to deep clean your bottle, you can fill it with half water, half vinegar, shake it up and let it soak for a few hours or overnight. Then rinse with warm water and dry.

Are stainless steel water bottles safe?

Yes. Stainless steel does not leach chemicals when heated. Look for 18/8 food-grade stainless steel, which refers to 18 percent chromium and 8 percent nickel and is one of the highest grades of stainless steel that is resistant to corrosion and commonly used in the food industry.

What Experts Say

“Staying hydrated is key for not only your body’s performance but also mental clarity and productivity—and it’s possible to reap the benefits of hydration without resorting to single-use plastic bottles. Stainless steel is a long-lasting material that is resistant to corrosion and does not leach chemicals when exposed to heat, making it a great choice for water bottles. When choosing a stainless steel bottle, consider what you’ll be using it for; if you’re active in sports choose a lightweight and slim bottle that can easily be carried, or if it’s your everyday water bottle choose one that fits in your bag or car’s cup holder. Overall, choosing a high-quality bottle made with materials that will last the test of time is better for you and better for the environment.” —Kristina Todini, RDN
