Always plan according to the needs of the primary user. This is important so you will know what kind of materials and features you need. A bathroom for children and adult would have different needs and you would use different features, too. For a child's bathroom, use non-skid surfaces and rounded edge to avoid injury. You can also place anti-slip mats. You can have adaptations for disabled persons by having grab rails to walls and close to the toilet. Consider a wall-hung sink so that people who use wheelchairs can move closer to it with ease.
