The “family toilet” of the mobile toilet refers to the “third toilet”, which refers to the toilet specially set up in the public toilet for the disabled or assisting relatives (especially the opposite sex) who cannot take care of themselves. Applicable situations include daughters assisting old fathers, sons assisting old mothers, mothers assisting little boys, and fathers assisting little girls.

Under normal circumstances, the “third bathroom” is set at the most conspicuous position at the entrance of the bathroom. In the past, when my father brought his young daughter to play, he would go to the disabled toilet, but he often felt embarrassed. The emergence of the “third bathroom” is expected to alleviate such problems.

However, the “third bathroom” also puts forward higher requirements for bathroom products. Its standards are stricter than general toilets. For example, in internal facilities, it should include multi-function desks, child safety seats, safety grab bars, clothes hooks and pagers, etc.; the ground anti-slip standards are also higher.

It can be said that the upgrading of mobile toilets has made the majority of social groups a real beneficiary.
