Find the best baby bath thermometer. Take the guesswork out of bath time with our picks for the best bath thermometers. Get accurate temperature readings and keep bath time safe and fun!
Getting a quick, accurate baby bath temperature before your wiggly baby gets into the water (and starts screaming because it’s too hot or too cold) makes bath time a lot less stressful for parents – and nicer for your baby, too.
Babies’ skin is much more sensitive than adults’, which is why it’s so important to get your baby’s bathwater temp right before they get in the tub! It’s a safety issue along with a comfort issue.
Take the stress out of bath time by investing a little into an easy to use bath thermometer for baby…and stop guessing about bath temperature!
The Best Bath Thermometers for Babies and Kids
Bath thermometers take the guesswork out of your evening routine. We’ve rounded up what we think are 5 of the best baby bath thermometer brands to choose from.
- Best Overall Bath Thermometer (+ Most Non Toxic Choice) – Mothermed Floating Baby Bath Thermometer – Made from non-toxic food safe polypropylene, this is the most non-toxic baby bath thermometer I could find that’s currently available on Amazon. A water thermometer that also doubles as a room thermometer. Fahrenheit only.
- Our Second Choice – B&H Floating Duck – Resembling a classic rubber duck bath toy with a digital water thermometer and clock. Doubles as a room thermometer, and works with either Fahrenheit or Celsius. Made from PVC and ABS, which is a con in my books.
- Simplest to Use – The Turtlemeter activates instantly once in your baby bath, making it really easy to use. It’s also got a color coded display so you know if the water temperature is too hot, too cold, or just right. Fahrenheit only, and only meant as a bath thermometer to measure water temperature – not room temp.
- Cutest Bath Thermometer – Dreambaby Room and Baby Bath Thermometer – This adorable crocodile measures in both Fahrenheit and Celsius, and has a double life as a bath thermometer and room thermometer. Automatically turns off at 30 minutes so you don’t have to worry about running down the battery.
- Best Value – Munchkin White Hot Safety Ducky – This isn’t a bath thermometer per se, but rather an indicator if the bath water is too hot. Unfortunately, there isn’t much available online about what this duck is made of. Sold in a set with a few bath toys.
Best Bath Thermometers Reviews
Best Overall (& Best Non Toxic)
Made in the shape of a cheerful stingray out of BPA-free materials, this thermometer displays the water temperature in Fahrenheit and will give you a “hot” warning when the water is too hot or a “cold” warning when the water is too cold.
I like that this stingray shaped bath thermometer is made from polypropylene – the same food safe material used to make plastic baby bottles. In my opinion, it’s a safe choice for this kind of usage, and I’d feel okay leaving it in the bath for the duration of bath time.
Simply shake the stingray to activate it and the temperature will stabilize to an accurate reading in about one minute. It provides intermittent measurement, meaning it refreshes every 5 seconds or so.
It takes one CR2 battery which is included.
Made in the shape of the classic rubber ducky, this thermometer displays both the temperature and the time so that you won’t lose track of either. It works to quickly get the baby bath tub temperature, as well as a room thermometer.
This thermometer will float in the tub with your little one and send a beeping or flashing alarm when the water is either too hot or too cold. It can display the temperature in either Fahrenheit or Celsius, and measures your preference automatically, so you can focus on your little one.
I don’t love that this duck is made out of PVC and ABS. Personally, I wouldn’t leave it in the tub for longer than necessary or use it in place of non-toxic bath toys – pop it in to get a read, then take it out again. And I wouldn’t let my little one put it in her mouth.
Requires two LR44 batteries, which are included.
Simplest to Use
Taking the guesswork out of the tub water temperature, this thermometer has a super-simple color-coded LCD display so that all it takes is a glance to monitor the water. It instantly activates in water, meaning no fussing around to turn it on.
This thermometer is in the shape of a friendly little turtle that floats around the tub with your little one. It will change to red if the water is too hot, blue if the water is too cold and green when the water is just right.
The temperature is displayed in Fahrenheit and will automatically be shown once placed in the water. It updates every second so that you will immediately know if the water temperature is becoming too hot or too cold.
It takes three AAA batteries, which are included, and is a fun choice for ocean loving kids!
The Most Adorable
This adorable crocodile-shaped baby bath thermometer can give you readings in both Celsius and Fahrenheit and features convenient lighted signals when the temperature is not ideal for your baby.
The Dreambaby thermometer is BPA-free, making it safe for your little one to play with while it floats in the tub. It’s also completely waterproof and can be submerged in the water without affecting its performance.
The temperature of the tub water is clearly displayed and will be updated every ten seconds. It will turn red if the water is too hot and green if it’s become too chilly.
Additionally, it can take the room temperature so that you’re aware of any changes that need to be made to keep the bathroom and your baby’s room comfortable.
It comes equipped with batteries for convenience and has an automatic 30-minute shut-off to save the battery life.
The Value Pack
Made to look like a classic rubber ducky, this is unlike the other bath thermometers on this list, as it doesn’t actually display temperature readings. Instead, it displays “hot” on the bottom when bath water is too hot. Completely water-tight to prevent mildew and leakage and sold as a set with other toys.
Simplistic in its design, the ducky has a straightforward display disc on its bottom side. It will either be blue for the ideal water temperature or say “hot” when it is too hot, so you can make sure bath time doesn’t hurt.
There is no need to mess with an on/off switch, as it will start working as soon as you place it in the tub water.
As a pro, this thermometer doesn’t require batteries at all. As a con, it doesn’t display actual temperature readings.
Tips for Getting the Perfect Baby Bath Temperature
Bath thermometers are a great way to take the guess work out of bath time – but I thought I’d share a few more tips!
Always fill your baby bath tub with water before placing baby inside it. Otherwise, you really run the risk of the water slowly heating up to be uncomfortable for your little one, without realizing it’s happening. The ideal baby bath temperature is around 95 to 102 degrees F.
Many of these thermometers look like a bath toy. However, I’d really encourage you to not let your kids play with them, and opt for fit-for-purpose non-toxic bath toy brands, instead.
I hope my research will help you choose the best baby bath thermometer for your family. If you know any parents who would benefit from this article, please share!
