After thorough cleaning the shower floor and degreasing with alcohol glue the stickers
very well and without any problems without bubbles. The transparent, colorless film is so thin that no
"Stages" can be seen, yet stable. The points reflect a bit fainter than the
Shower floor that looks at "clever" arrangement actually pretty good and "professional" from,
as if it were roughened at the factory. The arrangement one can in the film 28 points
adjust so that the individual use ("passageways") is taken into account.
When stepping into the shower tray, the stickers serve their purpose very well,
the shower floor is very safe and nonslip even when wet.
I find it is a simple, fast and cheap way to be implemented
to make the shower safer and also looks quite nice.
