Based on the image provided, the following portions of the text suggest that bathwater was a shared resource in 19th-century homes:
1. "The middle class... usually made do in the 1860s with one big bath on Sunday night, in which the whole household 'took part'..."
This explicitly states that the entire household participated in one big bath, which clearly indicates that the bathwater was shared among the members of the household.
2. "And at Mrs. Browning’s Academy in Blackheath for young ladies a weekly bath was, charged as an extra."
While this part doesn't directly state that the water was shared, charging extra for a weekly bath suggests that it was not a common practice for each individual to have their own fresh bathwater. This could imply that when a bath was taken without the extra charge, sharing might have occurred to reduce costs.
These portions of the text should be cited as evidence to support the statement about bathwater being a shared resource in 19th-century homes.
