Tervis tumblers are popular for their durable design, fun prints, and ability to keep beverages at the perfect temperature. As a Tervis user, you may have found yourself wondering, are Tervis microwavable? This question is not only crucial for those looking to heat their beverages but also for overall safety and longevity of these beloved tumblers. This article dives deeply into the compatibility of Tervis products with microwave use, exploring materials, safety concerns, and best practices.
Understanding Tervis Manufacturing
Before diving into whether Tervis tumblers can be used in the microwave, it’s essential to understand how they are made. Tervis, founded in 1946, specializes in producing insulated drinkware using a combination of high-quality materials.
The Material Matters: What Are Tervis Tumblers Made From?
Tervis tumblers are primarily made from two materials:
- Polypropylene – Known for its durability, polypropylene is a plastic that withstands heat and cold effectively.
- Stainless Steel – Some Tervis products feature a stainless steel layer for additional thermal insulation.
These materials are designed to keep drinks hot or cold for extended periods, which speaks to their insulating properties. However, the question remains about their microwave safety.
Can You Microwave Tervis Tumblers?
The short answer is: Not all Tervis products are microwave safe. However, several tumblers are specifically designed for microwave use. Understanding which ones are suitable and how to identify them is crucial for safety.
Common Features of Microwave-Safe Tumblers
To determine if a Tervis tumbler is microwavable, look for the following characteristics:
- Manufacturer’s Labeling – Tervis often includes labels on the bottom of the tumbler indicating whether it is microwave-safe.
- Material Type – Products made from polypropylene are typically safe for microwave use; however, anything containing stainless steel should never be microwaved.
Why Some Tervis Tumblers Are Not Microwavable
Understanding the implications of microwaving Tervis tumblers that are not designed for it is essential. Safety concerns arise mainly due to:

Are Tervis tumblers microwavable?
Yes, Tervis tumblers are generally microwavable. Most Tervis products are made from durable double-walled plastic that can withstand microwave heat without melting or warping. However, it’s essential to check the bottom of your specific tumbler for the microwave-safe symbol, as some designs may have limitations based on their materials or decoration.
Even if the tumbler is marked as microwavable, it is advisable to follow certain precautions. For instance, avoid exposing the tumbler to extreme temperature changes, like placing a cold tumbler directly into a hot microwave. Additionally, do not microwave any lid that may not be compatible with high temperatures, as it could warp or melt.
Can I put boiling liquid in Tervis tumblers?
Yes, you can put boiling liquids in Tervis tumblers, thanks to their high-quality construction and insulation properties. The double-walled design helps in maintaining the temperature of hot liquids while keeping the outer surface cool to the touch. This design minimizes the risk of burns when handling the tumbler after it has been filled with hot contents.
However, it’s important to let the boiling liquid cool slightly before closing it with a lid. If steam builds up, it can create excessive pressure and may cause the lid to pop off unexpectedly or allow hot liquid to spill out when opened. Always use caution and ensure that you do not overfill the tumbler to prevent this from occurring.
Do Tervis tumblers retain heat?
Tervis tumblers are designed with insulation in mind, which means they are quite effective at retaining heat. The double-walled construction creates a barrier that reduces heat transfer, keeping your hot beverages warm for a longer duration compared to traditional single-walled cups. This feature makes them ideal for enjoying hot soups, teas, and coffees while maintaining a comfortable grip on the outside of the tumbler.
That said, Tervis tumblers are not thermos-like in their heat retention. While they can maintain the temperature of hot liquids, they may not keep them hot indefinitely. If you plan to savor your hot drink over an extended period, it may still cool down gradually, similar to how regular mugs operate.
Will using Tervis in the microwave void the warranty?
Using Tervis tumblers in the microwave does not automatically void the warranty, provided the specific tumbler is marked as microwave-safe. Tervis products usually come with a limited lifetime warranty against defects in material or workmanship. However, using tumblers improperly—such as microwaving non-microwave-safe items—might not be covered under the warranty.
If your Tervis tumbler is damaged as a result of improper microwave use, it might be considered user error. Always refer to Tervis’s official guidelines and instructions regarding microwave usage, as following these recommendations will ensure you avoid any potential issues with warranties or product integrity.
Can I use Tervis tumblers for both hot and cold beverages?
Absolutely! Tervis tumblers are versatile and can be used for a wide range of beverages, both hot and cold. The double-wall insulation keeps your cold drinks chilled without condensation forming on the outside, so you’re less likely to have a wet surface. This makes them perfect for iced drinks, smoothies, or any beverage you might want to enjoy cold.
In addition to being great for hot beverages, such as coffee and tea, their design ensures that they are comfortable to hold regardless of the temperature of the drink inside. Just be sure to follow any specific care instructions provided with your tumbler to maximize its lifespan and performance with different types of beverages.
Are there any beverages I should avoid putting in Tervis tumblers?
While Tervis tumblers are suitable for a variety of beverages, it is wise to avoid putting any liquids that are overly acidic or corrosive, such as citrus juices or vinegar, for prolonged periods. These substances can potentially damage the tumbler’s internal lining or decorations over time. The main concern would be the aesthetic features rather than the structural integrity of the tumbler.
Additionally, avoid using Tervis tumblers with carbonated drinks if they are sealed with a lid. The pressure buildup from carbonation can cause the lid to pop off and might create a mess. For carbonated beverages, it’s best to use the tumbler without a lid to allow carbonation to escape safely.
How do I clean Tervis tumblers safely?
To clean your Tervis tumblers safely, hand washing is often recommended to preserve their vibrant designs and insulation properties. Use a mild detergent and a soft sponge to gently scrub the outer walls and inner surface. Avoid using abrasive cleaners or scouring pads, as they may scratch or damage the plastic.
