RITA and SAPPHIRE series bearing modern lines offer counter-top or counter-top embedded application options for its basin options matched to wall-suspended toilet bowls. With rectangular and oblong geometrical configurations, RITA and SAPPHIRE series offer a plainness which is a continuation of the minimal SEREL line to a space. The basins which have two different application options for either series come in 60x40cm format and are fit to be used with counters or furniture. Basin options located on counters may be chosen but there is the option which has the same lines which may be embedded on the counter. The basins which afford ease of cleaning with their plain and soft lines have a common component which is the ceramic washing group lid. Toilets bowls which allow linear integration with basin options which operate at full function with 4.5 liters of water together with embedded toilet bowl tap which is one of the most recent period innovations by SEREL, also offer the option of using hot or cold water f or personal hygiene. RITA and SAPPHIRE suspended toilet bowls which are compatible with new generation SEREL bowl lids with SEREL SilentClose® and SEREL EasyRelease® functions offer as an option quiet and slow closing of lid sets. These lids also allow the bowls to be cleaned easily, thanks to easy dismantling and mounting functions by just pressinga button.
