Dolores O' Riordan, who died suddenly on 15 January aged 46, was found submerged in the bath in her room at a London hotel.
The coroner said that O'Riordan died as a result of a "tragic accident".
She passed away after drinking an excessive amount of alcohol, expert witnesses told the court at her inquest.
The singer had no injuries or evidence of self-harm, the inquest was told.
Today would have been O'Riordan's 47th birthday.
