  • Dual flush – uses both the traditional flushing system and a modern water-saving technology
  • Gravity flush – water is siphoned downwards. It’s quite powerful, but very loud
  • G-max flushing system – uses an extra-wide flush valve and flapper to clear more space for wider water flow. Without any constriction or blockages, the water can now travel faster into the bowl and with more strength. It also utilizes a powerful siphon jet to ensure all the waste will be cleared at once.

  • They have a less forceful/ powerful flush. The kind of water-saving technologies and flushing systems that can be installed in these toilets are generally less performing. This also means you’ll need to clean up after every use.
  • Comfort is not its strong suit. With a smaller seating surface area, its not as pleasurable as to would want it to be.
  • Reduced availability- more and more people are discovering the benefits and advantages of the elongated toilets over round toilets, hence, more brands are focusing on the ready demand, leaving the sales of round toilets to decrease gradually.
  • They are space limited. because of their appearance, you can’t and shouldn’t add a round toilet in a large and accommodative bathroom as it would look awkward. Round toilets are best suited for space-limited units – most especially commercial or public washrooms.
