An indoor Jacuzzi adds many qualities to a home. It will improve the value of your house, and you’ll also be able to enjoy the pleasures of a Jacuzzi year-round in total privacy. If you have the appropriate space, you can install an indoor Jacuzzi yourself, although you will need others to help you move it into position.

Step 1 - Prepare

Before you order an indoor Jacuzzi, you need to know whether your home can actually handle one. Not only do you need a space big enough to house the Jacuzzi, but your floor has to be able to support it. Take into consideration the heavy weight of the Jacuzzi itself; then add in the number of gallons on the spa. A gallon of water weighs 8.35 pounds. You may have to put the indoor Jacuzzi in the basement, but you might want to talk to a structural engineer first.

The other consideration is moisture. Running the Jacuzzi for 15 minutes produces the same amount of moisture in the air as a 15-minute shower. This means you’ll need to put in the same type of extractor fan as you would install in a bathroom to vent the moisture to the outside of your home. Failure to do this could cause a buildup of mold and mildew.

Ideally there will be a drain in the room where you install the indoor Jacuzzi; if not, if should be close enough to the outside that you can drain it with a hose. The flooring should always be waterproof.

Step 2 - Put the Tub in Place

You need to have your indoor Jacuzzi delivered to the curb. From there, you and your friends will have to move it into the house. Use a piano dolly for ease of movement. Make sure you have ample access to the indoor space.

Put the Jacuzzi in place and use a level to make sure it’s even in all directions. This positioning is vital to keep water from sloshing over the edges.

Step 3 - Wire for Electricity

The vast majority of indoor Jacuzzis run on 240 volts of electricity. A GFCI panel can carry a load of up to 60 amps. Unless you’re very comfortable working with electricity, hire a qualified electrician to install the panel and appropriate breaker.

With the panel installed, you can now install your extractor fan. Make sure that the ducting runs through the wall to the outside of your home. Locate the fan above the indoor Jacuzzi for best effect. The fan should have a minimum capacity of 80 CFM, although a higher rating is better. Also, try to buy a fan with a low noise rating.

Step 4 - Test Your Tub

With the power to the indoor Jacuzzi turned off at the breaker, check that the drain valve on the spa and the gate valves are closed. Before you fill the tub, clean it with a non-abrasive cleaner. Ensure the filters are set in place.

Now you can run a garden hose from the outdoors and start filling the tub. Check for any leaks and tighten seals where necessary. Once the indoor Jacuzzi is fully filled, turn on the power at the breaker. Balance the water chemistry before use. It can take anywhere from 8 hours to a day for the water to heat fully.
