The toilet is using some of the cold water available in your house.
Since the shower is suddenly sharing the cold water pressure with the toilet less cold water flows into the shower. This makes the water hotter.

The answer that the toilet is using some of the cold water that is available is correct. In most cases it is also illegal (currently) to install a two handled shower valve (which you didn't say you had). If this is a concern I recommend replacing the valve. This involves replacing the trim (handle and plate behind referred to as an escutcheon). The big job is going into the wall. The valve and body need to be removed.
The reason I recommend this is that new single control valves have a PBU (Pressure Balancing Unit). What happens is that when you flush the toilet the overall water from your showerhead will drop maintaining the temperature generally a 2 degree +/- variance. Worth the change if you are sharing bathroom/s.

Sometimes in a house the toilet and shower use the same pipes. So when you flush the toilet, it takes away some of the cold water from the shower, so you get a huge blast of straight hot water until the toilet fills back up. In my parents house ALL the pipes were interconnected, so when my mom did laundry, dishes, or ran the sank I'd get burned or frozen every time. :-)

water pressure of cold goes down in shower when toilet refills with cold water. In wealthy homes they actually have the toilet fill with hot water (to prevent sweating of the tank) so in those places the shower would get colder.

because it's drawing away the cold water from the shower, leaving only hot. you need to replace your valves on the shower with newer balancing valves to stop this.

everybody is right but did you know that it is now illegal to have a shower body with seperate temp.controls? Temp. Control shower bodys keep the temp. at a certian level so you cant scald yourself. New constructions all have to use it. In New York anyway...........

cause it pulls the cold water from the system...you get hot from the heater and the cold from the general plumbing....
