For women, in particular, cleanliness was one of the very highest virtues.
The daily wash usually involved collecting water in a ewer, heating it, then pouring it into a large basin to be used for scrubbing.
Baths in a wooden tub would happen less often, given it was a world without plumbing.
Water is heavy, and collecting it, heating it, and then getting it from the kettle into the bathtub was difficult.
Baths also required space, which was at a premium in most households.
