A new spa is a big investment, and the electrical work should be handled with care from the beginning. Harmony Electric provides professional hot tub wiring for Colorado Custom Spas customers throughout the Denver metro area.
We help prepare your home before delivery by reviewing your spa’s electrical requirements, installing the proper circuit, and making sure the setup is ready for safe, reliable use. That way, you can focus on enjoying your new spa instead of worrying about the electrical details.
Most hot tubs need more than a standard outlet. For many installations, Harmony Electric will set up a dedicated 220-volt spa circuit, install GFCI protection, and make sure the correct breaker is in place before delivery. The proper wire size depends on the spa model, location, and installation requirements, but 6- or 8-gauge copper wiring is common for many setups.
Our goal is to get the electrical work handled ahead of time so your Colorado Custom Spas delivery and installation can move forward without avoidable delays.

The breaker plays an important role in a safe, reliable spa installation.
Colorado Custom Spas Colorado Custom Spas has specific breaker requirements designed to support safe, reliable performance and help protect your investment for years to come.
Siemens breakers help support proper startup, reduce nuisance tripping, and keep the system protected from day one.
It’s a small detail that can make a big difference in how smoothly your hot tub runs after installation.
A smooth spa installation starts before delivery day. Along with the electrical work, your site itself needs to be ready so the delivery team can bring the spa in and set it safely in place.
That means clearing a path, preparing the location, and completing the electrical setup before the spa arrives. Harmony Electric handles the wiring side, giving you one less thing to coordinate once delivery is on the calendar.
The spa should be placed on a properly supported location before deliver day. It is also worth checking for tight access points, overhead obstacles, nearby windows, and anything else that could affect placement.
Some homes already have enough electrical capacity for a dedicated spa circuit. Others need a panel upgrade before installation can move forward safely.
A dedicated 50- or 60-amp spa circuit adds a significant load to your electrical system. If your existing panel is full, outdated, or already working near its limit, upgrading it may be the safest and most practical next step.
Harmony Electric can evaluate your panel before installation and let you know what your home needs. In some cases, adding panel space or upgrading the panel during the spa installation is the simplest way to get everything handled at once.

Technically, Colorado law allows homeowners to pull their own permits for their primary residence, but hot tubs are one project where we really don’t recommend the DIY route.
Here’s why: you’re dealing with 240 volts of electricity sitting right next to 400 gallons of water. That’s a combination that requires zero mistakes. When you hire Harmony, we handle the complex permitting process, ensure the crucial “bonding” (grounding) is perfect, and install the specific Siemens breakers that Colorado Custom Spas requires to keep your warranty valid.
Most installs require a dedicated 220 volt, 50 or 60 amp, GFCI protected power source with four wires. Colorado Custom Spas also notes that 6 or 8 gauge copper wire is commonly used for many models.

No. The delivery team is not responsible for hookup, foundation prep, or filling the spa with water.
If your delivery date is coming up, Harmony Electric can get the wiring, breaker, and circuit in place ahead of time so everything is ready when the spa arrives.
