When you're busy working all day, it can be easy to neglect one of the most important habits for your health: drinking a sufficient amount of water. Having a water bottle can be a friendly reminder to hydrate, and luckily, there is a slew of great options on the market. Water bottles come in a variety of sizes (from 17 to 40 ounces), materials (plastic, stainless steel, and glass), and style (solid colors or prints), so you'd be hard-pressed not to find the right one. From simple, budget-friendly options to more high-tech ones, here are the best water bottles to have on your desk.

Best Overall: S'well Stainless Steel Water Bottle

With three vacuum layers, the S’Well Stainless Steel Water Bottle is designed to keep your drink cold for up to 48 hours and hot for up to 24 hours (depending on the bottle's size). This is great for anyone who travels a lot for work because the copper wall prevents condensation from forming on the exterior of the bottle, keeping your bag or belongings dry.

Available in three sizes (9, 17, and 25 ounces), this water bottle has a variety of styles and colors to choose from, including solids like Pink Topaz and Blue Suede to floral prints and marble designs. Note that it's recommended to wash this bottle by hand.

Best Glass: Soma BPA-Free Glass Water Bottle

Glass is an ideal material for water bottles because it does not impact the taste of what you're drinking the way some plastic bottles can. There’s just one problem: most glass bottles break very easily. Enter the Soma BPA-Free Glass Water Bottle, which has a silicone sleeve that covers most of its surface for protection. Better yet, the sleeve makes the bottle easy to grip and the glass is shatter-resistant.

It's also dishwasher safe though keep in mind that the cap, which is made from bamboo, must be hand washed. Available in both 17- and 25-ounce sizes, this water bottle comes in colors like White and Mint. 

Best Filtered: Larq Self Cleaning Water Bottle

The main problem with most filtered water bottles is that filtering water can be a time-consuming process. Luckily, Larq found a way to purify water without a traditional filter with its water bottle. It uses a built-in UV-C LED light, which eliminates bacteria in just one minute, and the lithium-polymer battery easily recharges through a MicroUSB connector. 

Unlike most purifying bottles, this 17-ounce one doesn’t require you to keep buying replacement filters—thus saving money in the long run. Additionally, this stainless steel bottle can keep drinks cold for up to 24 hours and hot for up to 12 hours. It also comes in sleek colors like Black and White and is recommended to be hand washed.

Best Stainless Steel: Hydro Flask 40-Ounce

There's a reason why Hydro Flask is one of the most popular brands for water bottles: they deliver high-quality products that are as functional as they are stylish. Generously sized at 40 ounces, this water bottle is ideal for busy workers on the go, yet it's small enough to fit in most bags.

Made of 18/8 pro-grade stainless steel, this dishwasher-safe bottle can keep drinks cold for up to 24 hours and warm for up to 6 hours. Plus, the wide mouth makes it very easy to open and drink from. It's also available in several colors including Black, White, Hibiscus, Fog, Spearmint, and Sunflower.

Best Plastic: Nalgene Tritan Wide Mouth

Nalgene Tritan

Plastic offers some advantages in that it won't dent like stainless steel can, and it’s lighter and far more durable than glass—perfect for those who need a water bottle for exercising after work. If you'd like to go with plastic, consider the Nalgene Tritan BPA-free water bottle.

This dishwasher-safe bottle can hold liquids as hot as 212 degrees Fahrenheit without melting, and you can even store it in the freezer as low as -40 degrees Fahrenheit. Both the bottle and lid are also leak-proof, and the wide mouth makes it easy to drink from. Choose from a vast selection of colors and styles like Blue and Purple Plaid.

Best Infuser: Live Infinitely Forever Fused

If you don’t like the taste of regular water, consider getting a bottle that can infuse water with fruit. The Live Infinitely Forever Fused water bottle is an excellent choice because it has an infuser built right in. Plus, it's made of BPA-free plastic and is dishwasher safe. And unlike other infusers, this one runs the entire length of the bottle, so the fruit can be tasted in every single sip. 

Not sure how much fruit to use or which ones to combine? This 32-ounce water bottle comes with a free ebook featuring 20 different fruit water recipes. It's also available in various fun colors, from Bright Teal to Rose Gold.

Best Budget: Contigo Purity Glass Water Bottle

Though it looks and feels high-end, the Contigo Purity Glass Water Bottle is a great budget-friendly pick. With a 20-ounce capacity, this bottle is on the smaller side, but it's still more than enough to last you a few hours of working in a coffee shop.

This dishwasher-safe water bottle features a sleek silicone sleeve, which helps prevent it from breaking. It also has a tethered lid, which not only assures the cap is never lost but also functions as a carrying loop. Even more, this bottle's wide mouth makes it easy to drink from. Choose from colors like Gray and Purple.

Best for Style: Rifle Paper Co. Canteen

Rifle Paper Co. 16 oz Wild Rose Canteen

In a collaboration with Corkcicle, Rifle Paper Co.’s Canteen comes in a slew of stylish floral prints. While it’s an ideal size for leaving on a desk or drinking on the go, it doesn't skip out on function. Drinks easily stay chilled in the triple-insulated stainless steel bottle for up to 25 hours or warm for up to 12 hours. It’s also BPA-free, so this bottle can be used as a thermos for soups during the colder months. While the screw-off cap stays on securely, it’s very easy to open and close. This 16-ounce canteen is recommended to be hand washed.

Best with Straw: Takeya Actives Water Bottle

With a straw built right into the lid, the Takeya Actives Stainless Steel Water Bottle is a convenient choice for traveling or commuting to work. The leak-proof lid is particularly easy to open and close with just one hand, and the protective silicone bumper on the bottom helps prevent damage. 

With double-wall vacuum insulation, it can keep drinks hot for up to 12 hours and cold for up to 24 hours. Along with two sizes (24 and 32 ounces), this BPA-free bottle is available in vibrant pastel colors like Blush and Lilac.
