Did you know that the average office worker tosses roughly 500 disposable coffee cups every year? Now imagine the pile that creates in your breakroom. A reusable cup isn't just about saving the planet, it can also save you money and keep your coffee tasting the way it should.
But not every mug fits an office life. Some leak in your bag, some are too small for a proper morning cup, and others feel like you're drinking from a thermos on a hiking trail. The question isn't really whether to switch, it's which one actually works at your desk.
In this guide, I share my 5 favorite reusable coffee cups for the office. They range from a sleek glass tumbler with a cork band to a double-walled stainless steel travel mug that holds heat for hours. Whether you chug espresso or sip a slow cold brew, there's a pick here that won't let you down.
How to Choose the Best Is the Keepcup Good for Office
Picking the right reusable cup for your desk is more personal than you might think. Below are the key factors I considered when narrowing down my picks.
Size and Volume
Think about how much coffee you actually drink in one sitting. An 8 ounce cup is perfect for a short black or a quick espresso, but if you refill only once during the morning, you'll want something closer to 12 or 16 ounces. The Brew Cork holds 16 ounces, which aligns with a standard takeaway coffee.
The 8oz cup is great for a concentrated brew but will leave a drip coffee drinker wanting more. Match your volume to your caffeine habit, not the other way around.
Material and Heat Retention
Glass cups look beautiful and don't add any metallic taste. They're also microwave safe, which is handy if your office coffee gets cold mid meeting. The trade off is that glass doesn't insulate.
Your drink will cool fairly fast. Stainless steel options like the Commuter Insulated Travel Mug use double wall vacuum technology to keep coffee hot for hours, but they are heavier and you can't microwave them. Plastic cups (the Cold Cup) are light and shatterproof, but they're best for cold drinks.
Consider your typical coffee temperature and how long you nurse it.
Lid Design and Leak Resistance
A lid that pops open accidentally in your work bag is a disaster. Look for a splashproof lid that seals firmly. The Brew Cork and the 8oz cup have lids that snap shut, but they are not fully leakproof if tipped sideways.
The Commuter Insulated Travel Mug has a flip lid with a locking mechanism that is genuinely leak resistant. If you carry your cup around the office or commute, a secure lid matters more than aesthetics. For desk only use, splashproof is fine.
Dishwasher Safety
You already have enough to clean. A cup that is dishwasher safe saves you time and reduces grime buildup. All five picks here are dishwasher safe, but check the details.
The Brew Cork's cork band can be hand washed if you want to preserve the natural look, but the glass itself is top rack safe. The 8oz cup and the Brew Reusable are both fully dishwasher safe. Avoid hand washing if you can; office kitchens are busy places.
Additional Features on Is the Keepcup Good for Office

- Reusable straw: The Cold Cup includes a straw, great for iced drinks or people who prefer sipping.
- Weight and portability: Lighter cups are easier to toss in a bag, but heavier glass cups feel more premium on the desk.

Is the Keepcup Good for Office FAQ
Can I use a KeepCup for hot coffee in the office?
Yes, absolutely. The glass models (Brew Cork, 8oz, and Brew Reusable) are designed for hot beverages. The glass can handle boiling water without shattering, though the cup will get warm to the touch.
The Commuter Insulated Travel Mug is even better for keeping hot coffee hot during long meetings. Just avoid plastic cups for very hot drinks if you are sensitive to taste; Tritan is BPA free but some people notice a slight plastic taste with extreme heat.
How do I stop my reusable cup from smelling in the office?
Rinse it immediately after use and run it through the dishwasher at least once a day. If you drink milk based coffees, the residue can sour quickly. For the cork band models, hand wash the cork periodically with mild soap to prevent odor buildup.
A weekly soak in diluted vinegar also helps remove stains and smells. Avoid leaving coffee in the cup overnight.
Which cup is best for an open plan office?
If you need quiet and don't want to draw attention, the Brew Cork or the 8oz cup are unobtrusive. They don't make clicking sounds when set down. The Commuter Insulated Travel Mug has a metal base that clinks louder.
The Cold Cup is quiet too, but the straw can make slurping noises. For discretion, glass cups win.
Are glass reusable cups safe in a shared office kitchen?
Yes, but handle them with care. Tempered glass is designed to be shock resistant, but it can still break if dropped on a tile floor. The cork band provides some grip to prevent slipping.
If breakage is a major concern in your office, the stainless steel Commuter or the plastic Cold Cup are safer alternatives. Always label your cup with a name to avoid mix ups.
My Research & Review Process
To compile these five picks, I compared manufacturer specifications side by side, focusing on material safety, capacity, lid design, and care requirements. I then examined verified buyer reviews across multiple retail platforms, looking for patterns in durability, ease of cleaning, and real world leak performance. I prioritized cups that offer a good balance of practicality and aesthetic appeal for an office environment.
I did not physically test these cups, so my recommendations are based on editorial analysis of product data and aggregated owner experiences. If you need a cup for a different setting (like outdoor hiking or barista use), the trade offs may shift.
Features I Considered
Shape: The shape affects how the cup feels in your hand and whether it fits under a coffee machine spout. Tumbler shapes are versatile, while tapered mugs fit cup holders better.
Material: Glass offers clarity and taste purity, stainless steel retains heat longer, and plastic is lightweight and shatterproof. Each material has a clear best use case.
Size: Capacity determines how often you refill. 8 oz is for short drinks, 12 oz is standard, 16 oz is generous. Match to your caffeine intake.
Lid: The lid design determines leak resistance and drinking experience. Splashproof lids are good for desk use; leakproof flip lids are essential for carrying in bags.
Care: All picks are dishwasher safe, which is a time saver in a busy office. Some cork bands require occasional hand washing to maintain appearance.
Weight: Lighter cups are more portable but may feel less premium. Heavier glass cups feel sturdier but add bulk to your bag.
If you're looking for a single cup that ticks every box for a typical office day, the Brew Cork Reusable Coffee Cup stands out. It looks great, holds a solid 16 oz, and cleans up easily. But if you need insulation or a smaller size, the other picks here are equally deserving.
