Best baby bath thermometers to ensure your baby is safe

The Nuby Penguin-shaped Baby Bath Digital Thermometer stands out for its practicality and adorable design. This thermometer features a cute penguin shape that not only makes bath time more fun but is also compact enough for travel. Mum tester Anne Lora praises its fast reading times and notes that it’s the most practical thermometer she’s used. “The cute penguin shape isn’t just charming—it’s also compact, making it easy to use at home or take along when travelling.” 

She adds, “This thermometer turns on as soon as it touches the water, and it’s been tested with other baby bath thermometers to ensure it gives accurate readings. The display is clear, but you might need to take a closer look to read the numbers easily, especially in dim light. It has a reliable battery life and is made from sturdy materials that hold up well with regular use.” 

It’s easy to keep clean and safe to use, providing peace of mind during bath time. Plus, it’s budget-friendly, giving you great value for your money. Its fun design and compatibility with different bath types make it a practical and enjoyable addition to your baby’s bath routine. 

In addition, this thermometer can be used in both the bath and the baby’s room, offering great value for money. It’s suitable from birth, is 100% BPA-free, and has a red light that flashes when the water is too hot, making it easy to see if you need to cool it down. 

Customers have found it reliable, with long-lasting batteries. Reviewers also love that it doubles as both a toy and a thermometer, adding to its versatility.

The Infantino Right Temp Light Up Otter might just be the cutest baby bath thermometer out there, featuring an adorable mother and baby otter design that floats charmingly in the bath. It’s incredibly easy to use—just place it in the water, and it gets to work. The vivid colours make it easy to spot, even in soapy water. The baby otter lights up in different colours to indicate water temperature: red for too hot, blue for too cold, and green when the water is just right. This colour-changing feature ensures it’s accurate and reliable, having been tested against other baby bath thermometers to confirm safe bath temperatures.

Mum tester Anne Lora, who used the product for two months, says, “Even though I personally don’t like baby bath thermometers without an actual screen reading, this one is an exception. It is accurate and beeps when the water is hot. However, a minor con is that the beep is quite loud and can startle my baby son. It also takes some time to stop, which can be annoying.” She also noted that the battery life is good, and the thermometer is durably made and doesn’t look cheap.

In terms of safety, this thermometer removes the guesswork from bathtime, providing peace of mind. It also doubles as a floating bath toy, keeping your baby entertained. Its construction is easy to maintain; just wipe it clean and air dry it after each use. With its combination of functionality and fun, the Infantino Right Temp Light Up Otter makes bath time easier and more enjoyable.

The Shnuggle Pebbly Baby Bath Thermometer makes bathtime stress-free by showing a heart on its display when the water reaches the perfect temperature. Our mum tester, Lily, loved how easy it was to use, saying, "This product is so easy to use, and anything to make baby bathtime easier is a winner!" The screen is also easy to read, even through bubbles, with Lily adding, "The heart light-up ensures the bath is at the right temperature and is easy to see."

The Pebbly® bath thermometer not only prioritises safety but also impresses with its modern design. Tester mum Charlotte appreciated its aesthetic appeal, noting, "It is aesthetically pleasing and blends in well when sat on the side of my bath at home, without being garish and bright." The thermometer signals if the water is too cold by blinking blue, lights up white between 30-37°C, and turns red if the water is too hot.

Mum tester Anne Lora found the design reminiscent of a spa, adding, "It has a spa-like vibe, reminding me of a hot stone from a massage, which adds a relaxing touch." She also liked the auto-on and off feature but noted that sometimes it takes a while to start. Additionally, while the thermometer adheres to international toy standards, it's best to remove it from the bath when not used, as it’s not a toy.

Priced at £10.95 (down from £19.95), the Shnuggle Pebbly Baby Bath Thermometer offers great value for peace of mind during bathtime. It was also shortlisted for Best Bathtime Product in the Mother&Baby Awards 2022.

Who doesn’t love a rubber duck in the tub? This classic-looking digital duckling won’t disappoint. Mum tester Anne Lora shares, “Whenever I think about bath times, a rubber duck comes to mind, so this one really gives me that nostalgic feel. It’s so cute that my baby son loves playing with it. It feels durable and will definitely last for a long time.”

In terms of accuracy, the digital duck provides reliable readings, alerting you to unsafe water temperatures. The clear display is complemented by a red warning light that illuminates when the water is too hot. Anne Lora also notes the flashing red dot feature, saying, “It’s a nice feature, but it’s subtle, and you might not notice it unless you pay close attention to the temperature screen because it’s a little dot on top of it.”

The battery life is somewhat mixed, according to reviews, so keeping spare batteries on hand might be a good idea. The thermometer is easy to use—just tap it on the palm of your hand to turn it on and start reading the temperature. It also features auto shut-off after an hour to save battery life.

This thermometer prioritises safety, providing a clear warning when the water is too hot. It is made from durable materials that can withstand regular use in the bath. Its playful design blends well with other bath-time toys, making it a fun addition to your baby's routine. At a budget-friendly price of £8.49, it offers good value for its features.

It works well with different bath types, making it a versatile choice for various bath-time setups. While there can be some delays in activation when first touching the water, once it’s up and running, it provides accurate readings. Overall, this thermometer combines practicality with a charming design, making bath time both safe and enjoyable.

The Tommee Tippee InBath Digital Bath and Room Thermometer is a fantastic choice for busy parents looking to simplify their baby care routine. This thermometer is a real winner when it comes to accuracy. It measures the temperature every five seconds, ensuring you get precise readings, so you’ll know exactly if the bath water is at the ideal temperature between 36.5°C and 38°C. If the water gets too hot, above 39°C, it flashes a red warning light on the clear LCD screen to alert you immediately.

The design is very practical. It’s not only cute, featuring the iconic Tommee Tippee star, but it also fits in seamlessly with any nursery or bathroom decor. The thermometer is fully waterproof and floats in the bath, so it’s always ready to use. Plus, it's easy to use: just tap it to turn it on and wait a few moments for the temperature to display. The large screen makes it straightforward to read, even with soapy water or in dim lighting.

The auto switch-off feature manages the battery life well. It ensures the thermometer turns off if it’s not in contact with water or the stand. This means you won’t have to worry about constantly changing batteries or wasting power if you forget to turn it off.

The thermometer is made from durable materials, so it feels sturdy and should last for a long time. In terms of compatibility, it works well with different bath setups, whether you’re using it in a standard bathtub or a baby bath.

Mum tester Anne Lora adds, “I love that it’s a two-in-one gadget, so I don’t need to buy separate thermometers for the bath and the room. It’s very easy to use, just tap to get the temperature, and the red flash for hot water is a great safety feature. Plus, the automatic switch-off helps save battery, which is a big bonus!”

Overall, the Tommee Tippee InBath Digital Bath and Room Thermometer combines practicality with great design, making it a valuable addition to your baby care essentials. It’s simple to use, offers accurate readings, and provides peace of mind with its safety features. For a price of £ 14.99 (was £19.99), it adds real value. This thermometer covers all the bases for both bath and room temperature checks.

The Liewood Kiera Bath Thermometer stands out with its charming bear design, which not only adds a playful element to bath time but also engages little ones. Its floating feature allows it to remain on the water's surface, making it easy to monitor the temperature while your little one splashes around.

Mum tester Breige Swift shares, “This is by far the cutest bath thermometer I have come across—my 16-month-old adored it straight away, grabbing the bear to give it a little kiss! It was easy to set up and simple to use, despite the larger-than-life instruction manual. It gives a clear and accurate temperature reading with flashing warning lights when the water is too hot (in red) or too cold (in blue), which is especially reassuring. It makes a nice little bath time playmate while floating on the water so that you can keep an eye on the temperature during bath time.” 

In terms of accuracy, the thermometer provides reliable temperature readings and has a clear numerical display, ensuring you know exactly how warm the water is. It also allows you to switch between Fahrenheit and Celsius, catering to different preferences.

The price is higher at £25, but the unique design and functionality may justify the cost for some parents.

We can't get enough of this bath and room thermometer by Phillips. As we all know, parenting is a costly business, so when we learned that this device could be used in both the bath and around the home, it piqued our interest. One mum Amazon reviewer, Yana, says, "This thermometer updates the temperature every 10 seconds, so you don't have to wait long to get your child's bath the perfect temperature. It also works as a room thermometer but doesn't have a backlight, so it is not ideal for readings at night in a child's dark bedroom. Great for the bath."

The gender-neutral green design would look chic on top of the bedroom drawers and in the tub with your little one. It's safe and fun for babies of all ages to play with, and the digital display is easy to use. While it’s more expensive than others on our list, we love a 2-in-1 gadget, and this thermometer ticks all the boxes; with the ability to be wiped down and used as a room thermometer as well, so it offers better value for money. Parent reviewers also thought it “feels durable” so should last well.

While it got top marks as a bath thermometer, one reviewer thought it was hard to read in the dark as a room thermometer because it is not backlit.

If your bathroom is already full of bath toys, or you're looking for a bath thermometer that can easily be transported on holiday, a bath thermometer card is a good investment. 

Unlike others on this list, you can't leave it floating in the bath with your baby, but its large liquid crystal display tells you at a glance whether the bath water is safe. The display line changes colour as it reads the temperature, from 32°-40°C+, so once the bar has reached between 36°C and 37°C, you know the bath water is at the right temperature.

While it can't double up as a toy and doesn't show the precise temperature, the unique display screen does mean it won't need batteries, and reviewers appreciated the simplicity, with one mum noting that it is: “quick, easy, simple, trustworthy and effective, good for travelling.” With no moving or breakable parts and no need for batteries, it's a good thermometer to pack in your suitcase, send to your co-parents' home or leave at the grandparents'.

If you're looking for a cheap yet effective bath thermometer, we’d recommend the Munchkin Hot Safety Bath Duck. 

It’s worth considering that, unlike other bath thermometers in this list, the Munchkin Hot Safety Bath Duck doesn’t tell you the exact temperature of the water. Instead, it displays whether the water is too hot with a disc on the bottom that changes colour, revealing the word 'HOT' when the bath water is too hot.

It's a fun toy for your little one to play with and is water-tight to prevent mildew, which reviewers appreciated, with one Amazon dad review, “I bought this rubber duck after getting a batch of smaller ones with holes in the bottom for a squeaker. I realised soon enough that this creates a great space for mould to grow, and bath time then turns into sitting in dirty water. This does the job and is a good size.”

While not knowing the exact temperature may be a drawback for some parents, the affordable price tag and playful element make this thermometer worth considering if you're on a budget.

A great option for crocodile-obsessed tots, this cute room and bath thermometer looks so friendly your little one definitely won't mind seeing it in the bath with them. This clever device re-checks the temperature every ten seconds to ensure the water doesn't become unsafe and automatically turns off after 30 minutes to save battery life.

With a red and green indicator telling you at a glance whether the water is too hot or too cold, this easy-to-use Croc is a must-have. Reviewers agreed, saying: “I've had the Croc for 18 months now, and my son loves it. It's very reliable. Also, the green and red flashing light is very helpful!” 

However, some reviewers would have liked to see a colour to show that the water was at the right temperature rather than simply too hot or too cold.

Similar to the Philips Avent Bath and Baby Room Thermometer, the Dreambaby Room and Bath Baby Thermometer can also be used in the baby’s room as a room thermometer, so offers good value for money as a 2-in-1.

OK, we know what you're thinking: 'How much?!' And we understand your concern about the price. You might think it's a hefty investment for a bath thermometer. However, this device is much more than simply a baby bath thermometer. You can't put it into the bath, but, instead, it is a bath in itself, and also serves as a baby scale, a bath thermometer, and remains useful until your child reaches two years old, making it a valuable long-term investment. Reviewers favoured this multifunctional use, saying: “We brought this bath for our new baby and love it. Our favourite features are the built in scales so we can keep a close eye on our daughter's weight, and also the built-in thermometer so we can see the temperature and make sure the baby is warm and comfortable.”

The innovative technology of this 3-in-1 digital baby bath allows you to precisely weigh your baby in the tub, whether there’s water in or not. As a bath, it's equally well-thought-out, with a non-slip insert at one end, making it suitable for newborn babies and space at the other end for infants who can sit up by themselves. Online, parents have hailed this as a must-have product, and many can't stop raving about it to family and friends, with one tester saying: "We have recommended this bath to our friends, and they love it! I would rate the bath 10/10 for quality/value for money.”
