A hot tub can be a relaxing addition to your backyard. Because they are large, electrically complex systems, installing hot tubs can be tricky. Modern hot tubs tend to be self-contained, which means there is no plumbing involved in the setup. Even so, installing a hot tub requires planning and compliance with city codes.
Choose a location for your hot tub
Make sure the spot you choose is large enough for the jacuzzi bathtub as well as some extra leeway for getting in and out and performing maintenance. A safe amount to allot is approximately 10 feet (3.0 m) by 10 feet (3 m by 3 m), but it depends on the size of your hot tub. Examine your city's building code to ascertain how far away from your home you must place your hot tub. Many codes require at least 5 feet (1.5 m) of clearance between your home and your property line. Two other regulations you need to consider when finding a place for the hot tub. The hot tub should be at least 10 feet (3 m) away from any overhead power lines, as well as 5 feet (1.5 m) removed from the spa panel. Water and electricity do not mix.
Create a route for the power to reach the hot tub
Most modern tubs are self-contained, meaning you won't have to run any plumbing in order to get the tub up and running. But electrical wiring is another matter. Cities usually have codes for using certain types of conduits, so make sure you talk with your local building department. When you have, decide if you'd like the conduit to run under or above ground. Most pumps will require an extra hard-wired circuit, one that's entirely dedicated to the electrical on the tub. A 240V, 50-amp GFCI (Ground Fault Circuit Interrupter) should be sufficient on many tubs. Multiple-pump tubs may require a 60-amp circuit. If you don't have familiarity wiring this kind of circuit, it's best to call an electrician to do it for you.
