Only lukewarm water in shower

Lukewarm water in shower, pressure seems ok. Hot water at both sinks in bathroom. All is well in rest of house. Kohler single knob. Replaced mixing valve kit (K71969) but no help. Any ideas? Thanks!

Was it like that before you did the replacement?

My first thought is that there should be an adjustment knob (pressure balancer - sounds like it's behind the cartridge you replaced) to limit the amount of hot water. It's there to stop scalding. Maybe you just need to reset it to add more hot water.

Good luck,
