Baby Bath Safety and Water Temperature (2026)
Baby bath safety from the AAP and CPSC: never leave a baby alone, keep tap water at 120°F or below, why bath seats don't prevent drowning, and add-ons to buy.

Quick answer
Never leave a baby alone in the bath, even for a moment: the AAP says children can drown in a few inches of water, and bath seats won't prevent it. Set the water heater so the faucet runs no hotter than 120°F and test the water with your wrist or elbow; a thermometer is only a backup.
In this guide
Bath time for a baby or toddler rests on rules that cost nothing, so they come first. Then the few products that help: a thermometer, spout covers, a mat, kneelers and a toilet lock.
How we chose: guidance comes from the American Academy of Pediatrics' bathroom safety page, the U.S. Consumer Product Safety Commission's Childproofing Your Home guide, CPSC's infant bath seat standard and its 2025 and 2026 bath seat recalls. The products are sold by Amazon.com and described from their listings, not tested by us.

For the tub itself, see our guide to baby bathtubs.
Stay within arm's reach, the whole bath
The AAP is blunt: "Children can drown in only a few inches of water, so never leave a young child alone in the bath, even for a moment."
In practice that means laying out the towel, the clean diaper and the pajamas before the water goes in. If the doorbell or your phone rings, wrap your baby in a towel and take them with you.
A kneeler like the Skip Hop or Nuby is not a safety device, but it makes staying down at the tub for the whole bath easier on your knees.
Bath seats don't prevent drowning
The AAP says "bath seats and rings are meant to be bathing aids and will not prevent drowning if the child is left unattended." The risk is that a seat makes stepping away feel fine. It isn't.
Bath seats have their own federal standard, 16 CFR part 1215, which incorporates ASTM F1967 and covers stability, the restraint system, suction cups and leg openings. The current version, ASTM F1967-24, has applied since January 4, 2025.
Seats that fail it still reach the market. From April 2025 to February 2026, CPSC announced recalls of at least six infant bath seats sold online, including Trankerloop, CheerKid, NFSVLB and YCXXKJ seats. The Trankerloop notice from February 26, 2026 gives the usual reason: the seats "are unstable and can tip over while in use, posing a risk of serious injury or death due to drowning."
Key point: we don't recommend a bath seat. If you already use one, check its brand in our recall checker, keep a hand on your baby, and never treat it as a reason to step away.
Water temperature starts at the heater
The AAP says to adjust the water heater "so the hottest temperature at the faucet is no more than 120 degrees Fahrenheit (48.9 degrees Celsius)."
CPSC gives the same number: "To prevent burns, the temperature on your water heater can be set to 120 degrees Fahrenheit or lower." CPSC adds that "anti-scald devices for faucets and shower heads can also be used to prevent scalding or burns"; which type fits depends on your fixtures, so ask a plumber.
For the bath itself, the AAP says: "Test the water with your wrist or elbow to check that it feels warm, not hot." Neither the AAP nor CPSC gives an exact bath-water temperature on the pages we used, so we don't either.
A thermometer is a second check, not the first:
- Dreambaby Whale Shark reads the water every 10 seconds and shows a red, blue or green light.
- Munchkin White Hot Ducky shows HOT at 104°F or above, Munchkin says. It gives no reading, just a quick warning.
Spout, tub floor and toilet
Three more AAP tips cover the rest of the bathroom:
- Spout cover: "Put a cushioned cover over the water faucet so your child won't be hurt if he bumps his head against it." The Skip Hop Moby and the Munchkin silicone cover both do this; check the fit against your spout.
- No-slip surface: "Install no-slip strips on the bottom of the bathtub." A suction mat like the Amazon Basics one does the same job for a toddler who stands up.
- Toilet: "Get in the habit of closing the lid of the toilet, and get a toilet lid lock." The Safety 1st OutSmart is one.
Lock up medicines, razors and cleaners in the bathroom too; our cabinet lock guide and babyproofing checklist by age cover those.

Frequently Asked Questions
Should I drain the tub right after the bath?
Yes. The AAP's bathroom safety page says: "Never leave water in the bathtub when it is not in use."
How do I keep a toddler out of the bathroom?
The AAP suggests "installing a latch on the door at adult height so the child can't get into the bathroom when you aren't around." It adds that any lock on the door should open from the outside, in case your child locks themselves in.
Which tap should my child turn on first?
The cold one. The AAP says that when your child is old enough to turn the faucets, "teach him to start the cold water before the hot."
Can I use a hair dryer in the bathroom with my baby there?
The AAP says it is better to use hair dryers and razors "in another room where there is no water," and to unplug and lock them away after use. An electrician can fit ground-fault circuit interrupter (GFCI) outlets in the bathroom.
