“…(the fire likely started in the area where)Â a bathtub on the second floor overflowed for an extended period of time…the fire was likely electrical 
in nature…Most of the damage was limited to the back one-third of the hotel, thanks to the building’s design, which includes “fire stops†— concrete barriers between sections of larger buildings that help keep potential fires from spreading…”
Investigators say a fire that tore through the Days Inn in Wausau Saturday evening started in the same area where a bathtub overflowed earlier in the day. Investigators from the Wausau Police Department, Wausau Fire Department, and the State Fire Marshal’s Office were at the hotel at 116 S. 17th Ave. Sunday to look into the cause of the blaze that displaced at least 20 long-term residents.
Wausau Police Capt. Greg Hagenbucher said investigators were notified of an incident earlier on Saturday where an amount of water damage was caused when a bathtub on the second floor overflowed for an extended period of time. The damage occurred in the same area where the fire was discovered. Hagenbucher said the fire was likely electrical in nature and does not appear suspicious.
