You may wonder what all the fuss is about when it comes to a rimless toilet because it looks just like any other toilet pan. It's what you can't see that makes the big difference though. Peek inside the bowl and instead of a hard-to-clean rim you'll find a smooth design that's just as efficient with water as any standard pan, sometimes even more so. A standard toilet rim is made up of small holes which can harbour germs and suffer from limescale buildup. Not rimless toilets. With specially designed pans that often shoot the water around the rim, rimless toilets don't have any nooks or crannies for dirt to collect.
