If you use our template, they’ll cover an area 42cm x 30cm (16.5 inches x 12 inches) approx. We recommend placing them where you step into your bath or where you stand to shower. If you wish to be extra safe, buy extra packs to cover a larger area. Please note, it is not recommended to spread out the circles to fit a larger area as this would provide less effective underfoot grip.
Our how many packs do I need guide gives more detail of layouts for traditional size and large baths and shower trays.
