Exploding toilets – dangerous bathrooms

The bathroom as we know it is a Victorian invention, but at first, it could be a dangerous place. Besides horrible cases of scalding in the bath, there are even reports that there were incidents of lavatories spontaneously exploding. The reason this might have been possible was that flammable gases such as methane and hydrogen sulphide, emanating from human waste, built up in the sewers and, in early toilets, could leak back into the home, where they could theoretically be ignited by the naked flame of a candle. Changes to toilets – beginning in the late 18th Century and continuing in the Victorian era – sorted the problem of gas leaking.
