Many showers and tubs at least in the US have no cut offs, so if you get a bad leak, you have to cut the water off at the Main. If you have to replace the faucet, you have to usually cut out the wall, maybe even tile to get the faucet replaced- then have a big hole to repair.
A running toilet is typically caused by the overflow tube, flush valve, or fill valve. Check the water in the tank to determine if it is running into the overflow tube. If the water is running into the overflow tube, the water level might be too high, or the overflow tube might be too short for the toilet.
