At its peak during the 1940s, Rotorua's Bath House was providing 60,000 to 80,000 baths and more than 25,000 massages annually but some of the treatments were far from what we see today.
When visiting the Bath House, men received treatments in the north wing of the building and women in the south.
People stayed in boarding houses and walked across the gardens for their treatments, which were prescribed by the balneologist.
Converted into modern currency, the cost of an initial consultation with the balneologist (£2.2s in 1913) was more than $450.
