Why bath temperature matters (safety, comfort, skin health)
Babies can’t regulate body temperature as well as adults. Water that’s even a few degrees too hot may irritate delicate skin or cause burns, while water that’s too cool can lead to shivering and an unhappy bath. Measuring is fast, easy, and removes guesswork.
How do I test bathwater?
Direct answer: The simplest way to test bathwater is with a reliable thermometer: aim for about 37°C (98.6°F) for newborns and 37–38°C (98.6–100.4°F) for older infants. Place the thermometer in the center of the tub, wait for a stable reading, and adjust water as needed.

Quick comparison: 3 thermometer types (fast overview)
- Digital stick thermometers — Accurate, inexpensive, great for quick dips in bathwater.
- Floating novelty thermometers — Fun, easy to read, good for older babies who enjoy bath toys.
- Infrared/instant-read thermometers — Contactless, very fast, best for caregivers who want zero immersion.
Best options and when to choose them
Each family’s needs are different. Below are the typical scenarios and the thermometer style that fits them best.
When quick accuracy matters: choose a digital bath thermometer
Digital models give reliable numeric readings and are typically the best all-round choice for newborns and infants. Many feature clear displays and auto-shutoff for battery life.
When you want bath time toys: choose floating thermometers
Floating thermometers look like ducks or boats — they measure temperature while entertaining your baby. Great for building positive associations with baths.
When you prefer contactless checks: choose infrared thermometers
Infrared thermometers give instant readings without touching the water. They’re convenient when you’re holding a little one and don’t want to reach into a tub.
How to use and calibrate your bath thermometer
- Fill the tub and swirl the water to even out hot and cold spots.
- Place the thermometer in the middle of the tub, not near the faucet or the drain.
- Wait until the reading stabilizes (usually 3–10 seconds for digital models).
- Check that reading against the target: ~37°C (98.6°F) for newborns.
- If using an infrared thermometer, hold it 1–2 inches above the water and follow the device instructions.
Repeat checks if you top up the bath or if other taps have been used nearby.
