Rite-Temp technology and user experience

Rite-Temp technology actively balances hot and cold input to keep temperatures steady as you adjust the handle, reducing abrupt shifts in flow that can interrupt your shower. The system also moderates pressure fluctuations from other fixtures on the same supply line, which can otherwise create sudden changes in feel. Anti-scald protection is built in to provide a safer, more predictable shower experience, especially for households with varying water pressure or high-demand use. The cartridge and its seals are designed to withstand aggressive water chemistry while preserving performance, so you can expect reliable function across seasons and usages. This part meets current plumbing codes and standards, reflecting Kohler’s commitment to safe and compatible replacement options.
