For several years I used to have the same problem in our house. Our situation was that originally our house shared a water supply with several other residences nearby. (This was a left-over from when city water was not available in our neighborhood.) The supply line to my house was old 1/2″ galv. iron pipe. This caused a limited flow rate, and the pressure was also low, thus whenever anyone was using the shower and another person turned on water anywhere in the house, the shower either turned ice cold or scalding hot. What I did to improve the situation (but not a perfect solution) was to tie into the city water supply which by that time had a water main in front of the house. I ran 3/4″ copper tubing from the meter to the house. The ideal cure would be to install an “anti-scald” shower valve which has an internal balancing device.
