Funnel bowl toilets

Funnel-shaped

— funnels include bowls that have the same (or almost the same) angle of inclination of all walls and a siphon hole located almost in the centre. Due to this, maximum efficiency in eliminating unpleasant odours is achieved; in addition, the funnels are quite easy to clean, and the need to use a brush occurs infrequently. On the other hand, when using such a toilet, there is a high probability of splashing; manufacturers resort to various design tricks in order to eliminate this inconvenience, but it is almost impossible to get rid of it completely — it is due to the shape of the bowl itself.
