Hello, my name is Sarah with Kohler Customer Service. I'm glad to answer your question. Unfortunately, our smallest toilet has a 10" rough in. I am sorry, we do not have a toilet with a 9" dimension. For additional assistance on this inquiry, please contact our Customer Care Center at 1-800-4KOHLER. (1-800-456-4537) Thank you for your inquiry and choosing The Bold Look of KOHLER.
Hello, my name is Jay with KOHLER Customer Service. I am happy to assist you with your toilet question. The two flushing types are both very good and recommended. AquaPiston • Our most powerful gravity-fed flush, which uses a canister design for enhanced flushing performance, virtually eliminates clogging and makes for a cleaner bowl. • The AquaPiston design and seal eliminate leakage problems commonly associated with traditional rubber flappers. • The yellow seal was designed to fight the conditions that cause leaks, including wear, tear, shrinkage and swelling. • The easy-flush actuator is great for households with small children or people with physical limitations. • Water enters the valve from 360 degrees, creating a smooth, consistent water flow from all sides, increasing the power and effectiveness of the flush. Class Five Single-Flush • The canister flush valve on these models allows water to flow into the bowl from all sides, increasing the power and effectiveness of the flush. • The durable canister design has 90% less exposed seal material than a 3-inch flapper for leak-free performance. • The universal red seal lasts longer because only a small area is exposed to tank water.
