AS1428.1 Grab Rails & Wall Mounted Shower Seats Explained

This standard is required only for public buildings. For private residences/independent living, the users individual requirements must be considered. We recommend an occupational therapist come and assess your home to find the best solution for your needs.

AS1428.1 ‘Design for access and mobility’ was created to allow people with disability to travel more and live a more independent life outside their home. For public bathrooms and toilets there are specific requirements that public bathrooms must comply with including for grabrails, handrails and shower seats.

This page includes information regarding the sections of AS1428.1 relevant to Avail products

Grabrails

Avail grabrails and shower seats are designed for assistance in bathrooms when using the toilet, shower, bath and small sets of stairs. Majority of our range comply and are approved to AS1428.1 as explained below.

Grabrails vs Handrails:

  • Grabrail – A rail used to give a steadying or stabilising assistance to a person engaged in a particular function
  • Handrail – A rail used in circulation areas such as corridors, passageways, ramps and stairways to assist in continuous movement

Shower Seats

These are seats that are attached to the shower wall. They can be folded when not needed.

Only dimensions for DDA/wheelchair showers are specified in the AS1428.1 standard, Ambulant showers are not specified. DDA/wheelchair showers require a minimum width of 960mm to allow the user to slide along from the dry area into the wet area. For ambulant showers smaller seats are suitable, including our Liberty 350 wall mounted fold up shower seat.

AS1428.1 Section 17 Grabrails

The full Avail Calibre Mod range and Glance range are approved and exceed the AS1428.1 standard having been tested to 150kg in all directions.

Our Calibre Ergo range is outside the standard (smaller 25mm diameter rail) because they are more ergonomic for children and small hands and for use as heavy duty towel rails

Requirements for AS1428.1 – 17 Grab Rails

a) Shall be between 30-40mm outside diameter

b)Exposed edges and corners of grabrails shall have a radius of not less than 5mm

c) The fastenings and materials and construction shall withstand a force of 1100N (approx. 110kg) applied in any            position in any direction without deformation or loosening or rotation of the fastenings or fittings

d) Clearance above grab rail and adjacent surface shall be not less than 50mm and not more than 60mm. Clearance above a horizontal grabrail shall be not less than 600mm. Clearance below a horizontal grab rail shall be a minimum of 50mm except at fixing points

e) Grabrails shall be fixed so that there is no obstruction to the passage of the hand along the top 270° arc of horizontal and angled grabrails and no obstruction to the passage of the hand for the full length of vertical grabrails.

Clause 17(e) does not state that the passage of the hand must be uninterrupted along the entire length of the grabrail rather just horizontal, vertical and angled sections. T Bar shower rails and Calibre Angled rails are compliant for this reason. Unlike handrails which must be continuous for their full length, grabrails may consist of multiple sections. For handrail requirements see section ‘12 Handrails’ of the standard.

AS1428.1 Section 15.5.9 Folding Shower Seat

Avail wall mounted fold up shower seats have been tested and approved to the AS1428.1 standard for Ambulant and DDA bathrooms.

For DDA/wheelchair accessible showers our 960mm wide seats are required.

Requirements for AS1428.1 – 15.5.9 Folding Shower Seat:

Self draining, slip resistant, edges rounded minimum 2mm, front corners rounded 10-15mm, fold upwards and when folded grab rail must be accessible, be able to withstand 1100N (approx. 110kg) in any direction at any position.

Avail wall mounted fold up seats do not have drain channels, instead they are slightly tilted back so the water runs off the back. They have been tested to withstand 150kg in all directions to exceed the standard. The seat without the fold down leg must be installed into a wall supported by timber studs with additional horizontal noggins or concrete/brick. Avail seats with the fold down leg can be installed into a single vertical timber wall stud allowing for retrofits into existing bathrooms.
