World leading anti-slip shower tray

''The surface was very comfortable and quite sensual a bit like reflexology''*

* Ulster University User Experience Report

User Experience Testing

A key requirement of the design brief was that our shower tray should deliver a verifiable positive user experience. Classic Marble (Showers) Ltd engaged the Podiatry Department at Ulster University to investigate and report on user perceptions of the SENSTEC Anti-Slip Shower Tray.

The entire report can be found at senstecshowertray.com Individual subject comments were very positive in terms of product design (94%) and some subjects found the experience of standing and moving in the tray therapeutic for their feet. 88% of subjects reported a high degree of comfort when standing and moving in the SENSTEC Anti-Slip Shower Tray. Various Post-test comments are shared throughout this website. It is important to note that the study protocol was followed diligently and that tests were conducted in line with the German DIN 51097 standard in relation to contaminant concentration and flow rates. Success! As a result of the University of Ulster Study the SENSTEC Design was turned from Prototype to Tooling.

Pendulum Test


Pendulum Testing

BS 7976-2:2002

Third Party, Independent, UKAS Certified Laboratory Testing

In simple terms the Pendulum is a swinging arm. The bottom of the pendulum is fitted with a rubber foot. When the pendulum is released from its starting position the rubber foot strikes the surface with the Anti-Slip properties. The distance travelled by the pendulum after striking the sample determines the Pendulum Test Value (PTV). This swinging motion is carried out multiple times before a PTV value can be calculated.

The Pendulum Tester is universally recognised as an effective floor slip resistance measuring device. It is the subject of many international standards and is the preferred test method of the UK Slip Resistance Group (UKSRG) and the Health & Safety Executive (HSE). Owing to its size and portability, it can be used both on site and for laboratory testing.

Our UKAS accredited laboratory results report an average PTV value of 37 for the Senstec Anti- Slip design, placing the product in the Low Slip Potential, the best classification possible.

This outstanding result was achieved with the addition of a soaping agent to replicate a true showering environment, even though this was over and above the standard requirements

Ramp Test


Ramp Testing

DIN 51097

Third Party, Independent, UKAS Certified Laboratory Testing

The Ramp Test involves a person walking forwards and backwards on a test sample at a predefined tempo, as determined by a metronome. A water and contaminant solution is pumped over the sample, at the same time as the apparatus is continuously tilted. The person is securely harnessed from above and although he/she is aware that the angle of inclination is constantly increasing, they are not aware of the actual angle. Throughout the test the person continuously walks forward and backward. The test ends when the person slips. The process is repeated multiple times with multiple people, with all measurements pooled to give a final result.

Due to the size and operation of the equipment this method is for laboratory testing only. Our UKAS-accredited laboratory testing reported an average result of 30°, placing it in category C, the best classification possible.

This meant that after extensive testing with the ramp and pendulum our design could be placed in the best classifications available. But what about the all-important user experience?
