Make your graham cracker crust. Most recipes will call for par-baking your crust. Assemble and par-bake your graham cracker crust on the middle oven rack as the recipe directs. Set it aside to cool while your prepare your cheesecake.
Wrap the springform pan. You can wrap the pan in three layers of tinfoil or one of the other methods mentioned in notes. Make sure none of the outside of the cheesecake pan is exposed.
Place pan into larger roasting pan. Once the pan is covered, place the foil wrapped pan inside the larger pan.
Add cheesecake filling. Pour your cheesecake batter into the springform pan.
Add hot water. Bring a teakettle or pot of water to a rolling boil. Before adding the hot water, I like to move my roasting pan close to my oven so I don't have to move it far to get to the oven so there's less risk of sloshing water around and getting into my cheesecake. Then carefully pour the hot water to the larger roasting pan, filling it up halfway.
Bake cheesecake. Move the pan carefully to the oven and place on the oven rack and bake the cheesecake.
Cool cheesecake in cake pan. Remove the cheesecake from the oven. Remove the springform pan from the water bath and allow to cool in the pan for 1 hour, Run a knife around the edges of the crust to loosen from the pan. This can help prevent cracks from forming, because as the cheesecake cools and contracts if the crust sticks it can cause the filling to crack. Then cover and refrigerate. I like to place a paper towel over the top of the cheesecake to prevent condensation from forming. The cheesecake will need to remain in the fridge for several hours in order to set up.
