3M 220C-R2X180 7641 Shower Tread, Clear, 2 inch

It's an excellent product, used in in my parents bathroom. Completely transparent and safe. It's three times the price of overseas so feel value for money is a bit less.

I used this tape in my elderly parents shower and bathroom. It is really good and I feel at peace knowing they’re safe and won’t slip.

Works perfectly in the bathtub - best I have ever had

This non slip bathroom floor tape works very well. Firstly they are translucent so the colours and patterns of the tile underneath shows through and the tape becomes almost invisible. Secondly after several weeks of use they are still stuck on firmly. No signs of delamination at the edges at all. (I did round the sharp corners before applying them to reduce the likelihood of the sharp corner peeling off) I also tried them on an outdoor staircase with a slightly rougher surface than the shower tiles. I found that the tape adhered better without using the recommended adhesive spray. Have not used them long enough outdoors to know whether they hold up as well the ones in the shower.

I used it on outdoor playground slippy metal stairs and it's very effective and extra safety for the kids I wish if the price was lower
