Hi Daniel,
Thank you for sharing!
Some shower valves have hot and cold supply stops that can be adjusted and accessed under the valve faceplate. If other showers in your home have the same issue, it may be due to water pressure. Some homes have whole-house pressure reducing valves that can be adjusted, or if water pressure is low in your community, your water company may offer additional insights.
Thanks again, and please let us know if we can help in any other way!
