Regular washing of children can prevent the spread of disease and improve health. Every house requires at least one facility where babies and young children can easily be washed. Ideally, this would include a tub for washing babies and a bath for washing children.

Ceramic hand basins are usually too small for washing babies and plastic baby baths may not be available in the local store. Residents often use the laundry tub to wash young children because it is large and at a good height. Many laundry tubs have washing machine bypass drains ensuring that the washing machine wastewater does not pass through the tub. This reduces the chances of the dirty washing water contacting the young child.

If incorporating a separate bathtub in the wet area, avoid using a combination shower/bath as this can be difficult and dangerous to use, particularly for older people or people with disabilities. Plan the bathroom to allow an adult to attend to at least two children in the bathtub at once. Set out the bathroom for maximum accessibility for a person with limited mobility. When specifying a bathtub, consider durability, size and how it will fit within the overall wet area layout.

Data shows that the laundry tub provides the greatest opportunity to wash a small child, with 92% of houses having a secure laundry tub. Bathtubs are available in more than half of all houses (59%).

Although 68% of houses had at least one hand basin, the small size of the basin and the close proximity of taps and spout may make the hand basin difficult to use to wash babies.

• Baths for washing children need to be safe and in good condition

Ensure

• B1.4.1.

  facilities are available for washing children in every house, including either a large hand basin, laundry tub or easily accessible bathtub, with tempered hot water, cold water and drainage to a waste water drainage system

• B1.4.2.

  to allow the safe washing of a child in a laundry tub, a working washing machine wastewater bypass to separate the child from any washing machine grey water discharge

• B1.4.3.

  bathtubs, hand basin and laundry tubs are fitted in accordance with local regulations

• B1.4.4.

  the specification requires the builder to provide a warranty for the waterproofing of the bathroom area

• B1.4.5.

  the specification requires a manufacturer’s warranty for the bath tub, hand basin and laundry tub

Consider

• providing a 70 litre flush line tub with hot and cold water supply in the laundry or bathroom, set into a bench top, which will provide space for changing nappies, drying and dressing a child
• alternatively, providing a larger hand basin in the bathroom to wash a baby
• when providing a tub in the laundry, specifying a bypass drain for the washing machine to prevent dirty waste water from the washing machine flowing into the laundry tub
• using a swivel spout and locating taps to prevent injury to children being washed in the laundry tub
• connecting the laundry taps to the hot water tempering device to prevent scalding, particularly if the laundry tub taps will also be used for hand washing or for washing children
• providing a bath tub for washing children
• fitting a grab rail around the bath for children and elderly people to safely step in and out of the bath
• providing a bench/seat near the bath for drying and dressing a child
• using a chain to secure the tub/bath plug
• providing a soap holder, shelves out of reach of children, towel rails, grab rails and hooks near the bath and/or tub
• incorporating a separate bathtub in the wet area, and avoiding a combination shower/bath as this can be difficult and dangerous to use, particularly for older people or people with disabilities.
