The traditional method to check baby bath temperature is to dip your elbow in the bath water. If it feels right on your elbow it is ok for your baby.
The right water temperature depends also on the age and the preference of the child. Because baby skin is a lot thinner than an adults, it takes only 5 seconds to suffer a 3rd degree burn.
This is why you should always check the bath water before putting your child in bath.
You can also use a baby bath thermometer to check if the baby bath water has the right temperature. The baby bath temperature should be between 36°C and 38°C.

To prevent burns from hot tap water, the temperature setting on the water heater can be turned down to 46°C or 120F. But if the temperature is set too low, bacteria may begin to grow in the tank.
Water stored at a temperature lower than 60°C is dangerous for developing the Legionnaire Bacteria.
In fact the ideal growth range for the Legionnaire Bacteria is from 35-46°C (95-115 F). But at 60°C Legionella dies instantly.
A solution to this problem is to have a plumber install an Antiscald Scaldshield Domestic Boiler.
This Temperature Actuated Mixing Valve is used to control the water temperature through a domestic hot water system. The valve delivers water at a temperature of 120°F while you set the boiler temperature at 140°F or higher to reduce the chance of Legionellae Bacteria growth.

With toddlers it is better to prepare the bath at the right bath temperature before you let your child in the bathroom.
