AS 4586 P3 Wet Barefoot
Shower recesses and bases should meet P3 minimum. Communal and aquatic showers warrant higher ratings, covered on the wet areas page.
Anti-Slip Coating for Showers
The Most Slippery Square Metre in the House
Homeowners, carers and facility managers: the shower is soap, water and bare feet on a smooth base, every day. Stellmann’s non-slip coating for showers is CSIRO-tested and certified to AS 4586 P3 for wet barefoot areas, and it is formulated to be safe on acrylic and fibreglass bases that acid treatments destroy. Nearly invisible, safe for skin contact, and applied without changing how the shower looks or drains.
What sets Stellmann apart: an acrylic-safe formulation. Most shower bases in Australian homes are acrylic or fibreglass, and most alternatives cannot touch them.

What is AS 4586?
AS 4586 is the Australian Standard slip test: the surface is tested wet and given a P rating from P0 to P5, and the higher the number, the more slip resistance it has.
Why Showers Are the Highest-Risk Slip Surface
Wet, Barefoot and Enclosed: Every Shower Has the Same Three Risk Factors
Older Australians are hospitalised for falls 12 times more often than adults aged 25 to 44, and same-level slips are the most common cause (AIHW, Injury in Australia 2024-25). A smooth, soapy shower base is the textbook version of that slip.
Home
A family wants Mum to keep showering independently without a rail-and-mat obstacle course.
Gym
A gym’s communal showers produce a member injury claim after a slip.
Acrylic Base
A homeowner’s acrylic shower base has become dangerously slick, and acid etching would wreck it.
Hospital
A hospital needs shower recesses that meet slip and infection-control requirements at the same time: rough textures that trap bacteria are not an option.
Every one of these is avoidable. Stellmann's coating reduces the slip risk and documents it, while keeping the shower looking exactly as it does now.
How it works
Safe Shower in Under an Hour, or Certified Overnight for Commercial Facilities
The process is the same whether you are treating one shower at home or a bank of showers in a commercial facility.
1
Profile
Call or send an enquiry. We assess the shower first: the base material and who uses it. Then we match the right Stellmann product, with P3 wet barefoot as the target. For communal and healthcare showers, an on-site assessment can be arranged, and higher-rated communal wet areas are covered on our wet areas and amenities page.

Treat
Certified installers coat the recess, or DIYers apply the 1.2m² shower kit in an afternoon. No acid, no etching, no grinding, and grout lines and drainage are unaffected.
3
Verify
Treated recesses are certified to AS 4586 P3 at the time of treatment and testing. Professional jobs carry the FEEL-THE-GRIP GUARANTEE* (terms and conditions apply).

Maintenance guide included: the right cleaners keep the grip and the warranty intact.

P3 wet barefoot rating
The AS 4586 class for shower recesses and bases, documented per recess.
Acrylic and fibreglass safe
Formulated for the bases acid treatments destroy.
Hygienic by design
Fine, even micro-texture, no ridges or tape edges to trap soap scum and bacteria.
Nearly invisible
No change to appearance, grout lines or drainage.

Shower Safety Compliance at a Glance
Compliance is documented at the time of treatment and testing. We recommend periodic re-testing for facilities.
Healthcare Facility Standards
Hospital and care-facility showers must satisfy slip resistance and infection control together. Smooth certified coatings do both; rough textures fail the second test.
NDIS Home Modification
Walk-in shower conversions and shower safety works are common NDIS modifications. We supply the slip-resistance documentation for funding applications.
Aged Care Quality Standards
Documented slip prevention in resident bathrooms and showers supports accreditation.

Questions, answered
Shower Coating FAQs
Is it safe on an acrylic or fibreglass shower base?
Yes. The formulation is specifically safe for acrylic and fibreglass, which is the main reason to choose a coating over acid etching. Acid will permanently damage those bases.
Will it change how my shower looks or drains?
No. The coating is nearly invisible and does not fill grout lines or alter falls to the drain. The shower looks the same, it just grips underfoot.
Can I do it myself?
Yes. The 1m² shower kit is roller-applied and designed for a DIY afternoon. For communal, healthcare or compliance-documented showers, use the professional service so the recess is certified and covered by the FEEL-THE-GRIP GUARANTEE* (terms and conditions apply).
What rating does a shower need?
P3 wet barefoot under AS 4586 for residential and standard commercial showers. Communal aquatic showers and constantly wet amenities warrant higher ratings; see the wet areas and amenities page.
How long before the shower can be used?
The coating is applied the same day and needs up to 12 hours to cure, so a shower treated in the morning is typically back in service that night. Exact cure time is on the product instructions and your free product match.
Will it change the look of a gloss tile?
On a gloss tile the sheen can change slightly toward satin; that is the only visible difference most customers notice.
