Can you install 2 shower heads in the same shower?

Buy to shower valves and install them so they are on opposite side walls or if you have a existing shower with one valve then the easiest way is to take out your old shower head and replace it by buying a chrome wye fitting that with two chrome nipples you can install to shower heads another way is by buying 3 chrome nipples and one chrome T and two chrome male by female IPS 90 and thread them into the the T and then you have room for two shower heads and they can be put side by side. The best way is to have two shower valves & shower heads, depending on your water supply and how you run your water pipes to the valves, most likely you will increase your water flow if not almost double and make sure you have at least a 2" drain & trap.
