Some common problems with Kohler Cimarron toilets include lack of plunge-ability and stoppages. Despite those issues, it is still a well-rated toilet. Feedback from customers and professionals alike overwhelmingly confirm that it is one of the most efficient toilets on the market.
Plunge-ability problems occur when customers are unable to find a plunger to use with Kohler Cimarron toilets. Claims include observations that the plunging hole is not round like the suction cup of a plunger and therefore it does not create a seal when plunging.
Other noted issues surrounding this toilet include seat quality and claims that the toilet starts to leak about two years after initial installation.
