This remains true for all modern water supply pipe materials such as copper, PVC (polyvinyl chloride), CPVC (chlorinated polyvinyl chloride) and PEX (a form of cross-linked polyethylene) pipes. Water volume in older homes is often reduced if the home has galvanized water pipes. Corrosion and calcium buildup inside galvanized pipes reduce the area inside the pipe, reducing the amount of water available to the fixtures. This can be remedied by replacing older galvanized pipes. Always start with replacing the horizontal pipes first as they are more likely to become restricted.
A licensed plumber can answer your questions by simply doing a visual inspection of the plumbing. Until the bathroom has been remodeled you can reduce the chances of scalding by limiting the water flow to the toilet by partially closing its supply valve (generally located at the wall or floor behind the toilet tank). This will cause the toilet to refill slowly. More importantly, add an “anti-scald” showerhead or tub faucet to protect against accidental scalding. Modern faucets typically have this feature built in, but it can also be added to existing faucets.
