Can you install a gas water heater in a bathroom?
Tuesday, January 14, 2020
No, you cannot put a gas water heater in a bathroom. A malfunction of the water heater or flue can allow carbon monoxide to flow into a bathroom and accumulate at a fatal level in what is typically a small room. It’s odorless, so you would be slowly asphyxiated without knowing what was happening. The building code specifically bans a water heater in a bathroom for this reason, unless in a sealed closet that receives combustion air from the outside, or it is a direct-vent type. Here’s the citation from the International Residential Code:
See our blog post Where are gas water heaters not allowed to be installed? for more details and other locations where gas water heaters are not allowed, and What is the difference between a regular water heater and a direct vent water heater? for a description of them.
