A:  Hi julied, this is Sarah with Kohler Customer Service. I am glad to address your question. The Highline Arc is marketed for Home Depot exclusively. The differences are minute and are related to sizing. To view and compare the dimensions of each, we recommend looking at page two of the specification sheets: Highline Curve: https://bit.ly/3x2YCCE Highline Arc: https://bit.ly/40D8ksS. Thank you for choosing Kohler.

A:  I bought two of these toilets two years ago. I don’t remember what the difference was at that time, but the toilet works great and we are completely satisfied with them.

A:  Hi Dave, this is Lisa with Kohler Co. I am glad to respond to your inquiry. Class Five flush valve canisters are found predominantly in the Wellworth® and Highline® product lines. AquaPiston canister configurations vary from model to model. The configuration is customized for each toilet model in order to obtain optimum flushing performance. Some factors that influence the canister's configuration include the toilet's tank size and toilet bowl shape. Class Five and AquaPiston canisters have identical flushing performance. Thank you for choosing Kohler.
