Most shower mats hold on with a ring of suction cups around the edge and nothing at all through the middle. That works for about two weeks. Then it quietly stops working, usually on the morning you are least paying attention. This one has cups across the whole of its back, corner to corner, so it grips over its entire area instead of at a dozen points around a rim.
No sliding. No corner lifting. No puddle underneath. Wet the back, press it down, and leave it there.
A mat that moves is worse than no mat at all
A bare wet tile is honestly slippery, and because you know that, you put your feet down carefully and nothing ever happens. The one that catches people out is the mat that has held for three weeks and has quietly stopped holding. By then you are stepping onto it the way you step onto a bath mat: wet, half awake, soap still on one foot.
That is what an empty middle costs you. Suction around the rim only holds while every cup on that rim is sealed, and the first one to let go takes its neighbors with it.
Press this one down and the whole underside is holding. It stays still when you turn on the ball of your foot.
It needs a smooth floor, and that is worth checking before you order
Suction has to have something to seal against. On glazed tile, an acrylic or enamel tray, or a smooth stone base, the cups close properly and the mat sits where you put it for weeks at a time without being touched.
It will not hold on a textured anti-slip tray, on rough riven stone, or across a grout line, because there is nothing flat there for a cup to close onto. If that describes your shower floor, this is the wrong mat. Better to know now than after it arrives.
One other thing worth doing: wet the cups before you lay it down. A dry cup rests on the floor and a wet one seals to it, and that single difference separates a mat still holding after a month from one that has lifted by Friday.
The water goes through it rather than under it
The mat is a field of holes rather than a solid sheet, so water leaves while you are still standing there instead of collecting beneath you. Lift it afterwards and the floor underneath is already half dry. A solid mat gives standing water somewhere to sit for a week, and by about Sunday you can smell the difference.
Every hole is ringed by a low raised collar, so what you are standing on is a field of rings rather than flat wet plastic. Wet skin catches on a ring in a way it never catches on a smooth surface.
Six colors, and each one runs the whole way through the material, so the back, the edges and the collars all match the face. Wet it, press it down, and stop thinking about your feet.
