What hot water temperature range is considered acceptable for resident use?

• A. 100 to 110 degrees F
• B. 90 to 100 degrees F
• C. 100 to 115 degrees F
• D. 105 to 115 degrees F

Answer: (C)

Hot water for resident use should be warm enough to be comfortable and effective for bathing, but not so hot that it could cause burns. A range of 100 to 115 degrees Fahrenheit hits that balance: it provides enough warmth for practical use, while keeping the risk of scald injuries low for residents, especially those with sensitive or fragile skin. Ranges below 100°F can feel too cool for comfort and effectiveness, and ranges above 115°F raise the danger of burns during normal use. So the 100–115°F range is the best fit for safe, comfortable resident care.
