The difference in water temperature between your shower and sink may be due to issues with the water heater, such as a malfunction or setting adjustment. It is recommended to check the water heater settings and possibly consult a professional plumber for further assistance.
A poor plumbing job. The pipes to the shower & sink share a pipe to the water heater and the pipe is not large enough. This causes the water pressure in the pipe to drop when the hot water is turned on at the sink while the shower is also on.
The plaming tubes are all conected.When the cold water run in kitchen the cold water at the shower become less,so with less cold water at the mix cold-hot (the balance is desterb),making the water hoter.Same if you turn on the hot in the kitchen the water will be colder in the shower.
Supply lines- Hot and cold water for each sink, bathtub, Jacuzzi tub, and shower. Cold water for each toilet. Drain lines- one for each sink, bathtub, Jacuzzi tub, shower, and toilet.
To ensure a consistent supply of hot water in the shower without affecting the hot water flow to the sink, you can install a thermostatic mixing valve. This valve will regulate the temperature of the water, allowing you to maintain a comfortable shower temperature while keeping the hot water flow to the sink unaffected.
For a DRY face: Morning- wash face (in shower or in sink) exfoliate face moisterize Night- wash face (in shower or sink) moisterize For an OILY face: Morning- wash face (in shower ir sink) exfoliate splash cold water on face (close pores) Night- wash face (shower/sink) moisterize (even if you have oily skin because it will reduce the appearance of pores) For a COMBONATION face: Morning- wash face (shower/sink) Night- wash face (shower/sink) exfoliate moisterize

Your water pressure is low. Consequently, when cold water is diverted to another application such as a toilet or a sink, the amount of cold water available at the shower mixing valve decreases as the low pressure is unable to keep up with the shower's demand. This causes a hotter mixture at the shower head. The solution is to either improve the cold water supply to the shower or to replace the shower control valve with a temperature compensating type. Pressure balancing is the cheapest and simply changes the shower temperature according to the pressure in the cold and hot water lines. When the toilet or sink is used, reduced pressure to the shower valve is detected and the valve reduces the hot water pressure, thereby maintaining the temperature. The more sophisticated approach is a thermostatic shower control valve. These are significantly more expensive, but will not reduce the pressure at the shower head (a drawback of the pressure balancing valve). The thermostatic valve would be required when one shower control valve is operating several shower heads. Moen, Kohler and Delta all make both types of control valves. They can be readily obtained from a local plumbing supply house.
Cold water and air tend to sink because they are denser than warm water and air. As they cool down, the molecules become more tightly packed together, increasing their density and causing them to sink. This creates a convection current where colder, denser fluid or air sinks while warmer, lighter fluid or air rises.
HOT rises COLD sinks
I assume it is the bathroom sink. Is there hot water in another sink in the house? In old steel pipes I have run across ones that get so rusted on the inside that water can not get through them. If anything has been done to the hot water line anywhere in the house, sediment or rust may have broken loose and plugged the fixtures.
Turn on your bathtub or shower hot then turn it off at last turn on your hot water for your sink. Hope this helps!
Probably not, but where does the water from the sink and shower go and what sewer problems are you having?
