Editorial policy

The bathroom poses unique dangers: drowning, scalding, poisoning, and slipping. A child should never be left unsupervised in the bathroom at any age under 5.

Key takeaways

  • Never leave a baby or toddler alone in the bathtub, even for a second
  • Children can drown in as little as 1 inch of water in under 60 seconds
  • Set water heater to 120 degrees F (49 degrees C) to prevent scalding
  • Install toilet locks before baby can pull to standing (around 8-10 months)
  • Store all medicines and personal care products in locked cabinets

Drowning prevention

Drowning is silent and fast. It is the leading cause of injury death in children ages 1-4.

  • Never leave a child alone in the tub, even to grab a towel. Take the child with you or drain the tub first.
  • Bath seats are not safety devices — the AAP warns they create a false sense of security
  • Empty the tub immediately after bath time
  • Install toilet locks — toddlers are top-heavy and can fall headfirst into a toilet
  • Keep bathroom doors closed and use doorknob covers to prevent unsupervised entry
  • Empty all containers — buckets, basins, and mop pails should never hold standing water

Water temperature safety

Scalding is the second most common burn in young children:

  • Set your water heater to 120 degrees F (49 degrees C) or lower
  • Always run cold water first, then add hot
  • Test water with your elbow or a bath thermometer (aim for 98-100 degrees F)
  • Install anti-scald devices on faucets
  • A child can get a third-degree burn in 1 second at 156 degrees F, or in 5 seconds at 140 degrees F
  • Turn the child away from faucets so they cannot turn on hot water

Bathroom safety checklist

  • Toilet lock installed
  • Non-slip mat in bathtub
  • Faucet cover (soft spout cover to prevent head injuries)
  • Water heater set to 120 degrees F or lower
  • All medicines in locked cabinet
  • Razors stored out of reach
  • Electrical appliances (hair dryers, curling irons) unplugged and stored away
  • GFCI outlets installed near water sources
  • Cleaning products locked away
  • Trash can with child-proof lid or stored in locked cabinet
  • Doorknob cover on outside of bathroom door
  • Non-slip rug outside the tub

Medicine and product safety

The bathroom is where most childhood poisonings from medications occur:

  • Store all medicines (including vitamins) in a locked cabinet
  • Never call medicine "candy" to encourage a child to take it
  • Keep products in original child-resistant containers
  • Dispose of expired medications safely (drug take-back programs)
  • Store personal care products (mouthwash, nail polish remover, perfume) out of reach — many contain alcohol
  • Keep the Poison Control number posted: 1-800-222-1222

Slip and fall prevention

  • Use non-slip mats or decals inside the bathtub
  • Place a non-slip rug on the floor outside the tub
  • Wipe up water spills immediately
  • Install a soft faucet cover to protect against head bumps
  • Keep the bathroom floor clear of clutter
  • Consider a step stool with non-slip surface for older toddlers at the sink

Frequently asked questions

Can a baby drown in an inch of water?
Yes. Infants and toddlers can drown in as little as 1-2 inches of water. Never leave a child unattended in the bathtub, even for a moment. If you need to leave, take the child with you.
What temperature should bath water be?
Bath water should be between 98-100 degrees F (37-38 degrees C). Always test with your elbow or a bath thermometer. Set your water heater to 120 degrees F or lower to prevent scalding.
Are bath seats safe?
Bath seats are not safety devices. The AAP warns that bath seats create a false sense of security and children have drowned in them. They can tip over or the child can slip out. Never leave a child unattended in a bath seat.
When should I install a toilet lock?
Before your baby can pull up to standing, typically around 8-10 months. Toddlers are top-heavy and can fall headfirst into a toilet and drown.
Where should I store medicines in the bathroom?
In a locked medicine cabinet or a locked container that is out of reach. Never leave medicines on the counter, even briefly. Children can climb faster than you expect.

Bottom line

The bathroom is one of the most dangerous rooms for young children due to drowning, scalding, and poisoning risks. The single most important rule: never leave a child under 5 unsupervised in the bathroom, even for a moment. Install locks, lower your water heater temperature, and secure all medicines.

If you are ever unsure about bath safety, remember: if you need to leave the bathroom, take the baby with you. No phone call or doorbell is worth the risk.
