Here are some guidelines for how to incorporate accessible toilets and showers into your building project. Check out the New Zealand Standards NZS 4121:2001 and NZBC G1/AS1 for more information.Accessible toilet facilities should be provided on an accessible route on the main entry level to all buildings and parts of buildings that are defined in the Building Act Section 118. In addition, in multi-storey buildings additional accessible toilets should be distributed evenly and throughout the building. Alternatively wherever toilets are provided at least one shall be an accessible toilet.
The provision of at least one unisex accessible toilet unit is a requirement of all toilet facilities. If two or more accessible toilets are provided, at least one shall have a pan position for the opposite hand.
Accessible toilets should be provided where the route to them will not traverse different tenancies within the building.
The number and type of sanitary fixtures required in a public building are determined from NZBC G1/AS1 table one or two as one means of compliance.
Accessible toilets should be designed to provide manoeuvring space so that people in wheelchairs may use each type of fixture. The images are examples of how to achieve compliance; however, in some cases there may be alternative ways of achieving compliance.
The minimum internal dimension of a compartment shall be 1,900mm.
All fixings and fixtures shall be provided as per the dimensions shown below.
Sanitary fixtures for people with disabilities shall be signposted as required by NZBC F8 “Signs” and located on an accessible route.
There shall be no direct line of sight between a general public area and a WC, urinal or shower. All fittings shall contrast visually to their background.
CUBICLE SCREENING FOR TOILETS
A hand basin must be supplied within the compartment and a complying grab-rail shall be provided (remember to provide fixing support for the grab rail when framing the compartment).
LOCATION AND CLEARANCE FOR WASH BASINS AND FITTINGS
Where showers are required for staff or public use and there is more than one provided, one of those facilities must be a wet-area shower for people with disabilities.
Accessible shower cubicles may be complete in themselves or be part of a combined accessible toilet/shower facility; however, if the drying space is used for dressing and undressing it shall be separated from the shower.
If two or more shower cubicles are provided, at least one shall have a seat and controls for the opposite hand.
