  1. Flushing mechanism: There are two flushing structures – gravity-flush system and pressure-assisted flush system. While the former is easier and ordinary, the latter is resourceful and uses less water.
  1. Aesthetic appeal: Buy a toilet that will match your bathroom’s interiors. Keep in mind that most models come in elongated and rounded bowl shapes. Pick something that compliments the décor and individuality of the bathroom.
