How to Plan Your Hot Tub Installation

Well, first things first, you need a good plan for your hot tub installation. This is an important step as you will be prepared and will make everything quicker. To get the most out of your investment, you need to carefully consider where to place the hot tub, how much it will cost, and what permits may be required. Now let’s get into the details.

The Right Location

Start by choosing the right place for your hot tub. These things are heavy enough that no one wants to move them several times, and no one wants to move them themselves. And to make it easier for you to decide, here are the main points you need to pay attention to.

  • πŸ‘« Convenience and accessibility. It should be convenient for you to approach the hot tub. For example, you can place it on your backyard deck or enclosed patio, and put steps next to the hot tub to make it easier for you to get into it;
  • 🏑 Privacy. You may want to shield your hot tub from nosy neighbors. Privacy screen, fencing, or rooftop terrace is a good choice to create a comfortable area for your hot tub experience;
  • View. A good view can add to your enjoyment while relaxing. Of course, it depends on where you are, but the view does play an important role and if you have a nearby mountain, forest, lake, or hill, then determine where it will be best seen from;
  • πŸ“ Last but not least is the surface. It should be flat and sturdy so that your hot tub stays in one piece. The most common and reliable bases are a concrete patio and reinforced deck. They will last you a long time and can withstand a hot tub with water and people in it.

Setting a Budget

Budgeting is like making a shopping list before you go to the store. It will help you stay on track and avoid overspending. Calculate how much you are willing to invest in a hot tub, but don’t just think about the initial cost. Consider also the running costs such as maintenance, electricity, and water. The budget should cover the hot tub itself, the cost of installation, and additional features and accessories you want to add, such as lighting or jets.

Necessary Permits

Think of the installation permit as a necessary formality. In many areas, a permit is required before installing a hot tub, and failure to obtain one can lead to complications later. 

The permitting process varies by location, so contact your local government or zoning department. They can help you complete the necessary paperwork and ensure that your hot tub complies with local regulations. Don’t worry, it’s usually not as complicated as it seems.

How to Prepare the Space

With a properly prepared place, the installation of a hot tub will be many times easier. First, we are talking about the foundation. You need a solid and level surface. Whether the hot tub will be installed in the backyard or indoors, a proper foundation is a must.

The foundation or floor must be able to support the weight of the hot tub when it is filled with water and people. In addition, electrical and plumbing connections must be thought out, so be prepared to plan and make changes to existing systems if necessary. Proper preparation for installation will ensure the longevity of your desired purchase.

How to Prepare the Space

Solid Foundation

Just as a house needs a solid foundation, your hot tub needs a solid foundation. After all, it supports the hot tub, ensuring that it is level and secure. If you are installing your hot tub outdoors, you can use a concrete pad or sturdy decking as a foundation. If you want to explore this in more detail, you can refer to our previous article on how to install a hot tub base. Having a solid foundation minimizes the risk of your hot tub sagging or becoming uneven over time.

Electricity and Plumbing

Now let’s talk about the technical aspects. Your hot tub needs both electricity and plumbing to run smoothly. As for the electrical part, it is very important to have a dedicated GFCI (Ground Fault Circuit Interrupter) circuit. This is necessary for safety as it helps prevent electrical accidents.

❗ Keep in mind:
If you are not an electrical expert, it is better to hire a professional to make sure that the wiring is done properly and complies with local codes.

In terms of plumbing, the hot tub will require water and drain connections. Some modifications may be required here if you are installing the hot tub in a new location. As with the electrical, plumbing work should be done by professionals who will ensure proper connections, prevent leaks, and ensure proper functioning. These technical aspects are the foundation of a hot tub, so getting them right from the start is the key to a carefree experience.

Electrical Connection

Electrical Connection

Now let’s talk about power. Here, we will look at 2 types of hot tubs: professionally wired and plug-and-play.

Professionally wired hot tub:

These hot tubs are not a DIY affair, as they involve electrical work that a professional electrician should do. They will set up a dedicated circuit with a Ground Fault Circuit Interrupter (GFCI) to ensure safety. It quickly breaks an electrical circuit with leakage current to the ground. It will protect your equipment and reduce the risk of serious harm from an ongoing electric shock. 

Plug-and-play hot tub:

They are designed to be more user-friendly and do not require professional electrical work. Plug-and-play hot tubs are typically equipped with a standard 120-volt plug that can be connected to a standard electrical outlet. This is a good choice for homeowners because such hot tubs are easier to set up, and they do not require installing a dedicated circuit.

Water Supply and Drainage

A reliable water supply and drainage system is necessary for a hot tub to function properly. If you need a better understanding of plumbing, it is recommended that you hire a professional to install these connections (it depends on the size and type of the hot tub, however, it is mostly for professional wired ones). They will ensure that water flows into and drains from the hot tub without interruption, preventing leaks and water-related problems. Remember that proper water supply and drainage organization is the key to long-lasting use of your outdoor hot tub.

Indoor Hot Tub Installation

Special Considerations

Why You Need a Hot Tub Enclosure

There are several reasons why the enclosure is an important component of a hot tub installation. 

  • It enhances the aesthetic appearance of the hot tub and serves a practical function. 
  • Enclosures help maintain proper temperature and humidity, providing a comfortable spa environment.
  • They also provide privacy and soundproofing, making relaxing in the hot tub more enjoyable.
  • In addition, enclosures protect from external influences, extending the life of the hot tub and reducing maintenance costs.

Safety and Maintenance

Safety and maintenance are of the utmost importance to hot tub owners. In this section, we will explain the precautions to take when using hot tubs and what maintenance work needs to be done to keep your hot tub in perfect condition.

Hot Tub Safety Precautions

Ensuring safety in and around the hot tub is a top priority. A clear set of precautions should always be kept in mind, and here are simple steps to follow.

πŸ‘£ Firstly, you need to keep an eye on the temperature of the water. Typically, the water temperature in hot tubs ranges from 100 to 104Β°F (37-40Β°C). Staying in it for longer periods of time at higher temperatures can cause overheating, so the amount of time you stay in it should be reasonable.

πŸ‘£ Also, never use a hot tub while under the influence of alcohol or drugs, as this impairs judgment and can be dangerous. 

πŸ‘£ Keep an eye on the water level so that it covers the jets but does not overflow. 

πŸ‘£ Those with long hair should be careful as hair can get in the nozzles. 

πŸ‘£ Finally, always supervise children in the hot tub and install a lock or safety cover when not in use.

These precautions will help create a safe environment for all hot tub users.

Routine Maintenance

Regular maintenance ensures that your hot tub runs smoothly and remains a clean and safe place to relax. 

  • One of the most important tasks is water care. Check and adjust the water’s pH level and sanitizer content to keep it free of harmful bacteria and algae. Hot tub chemicals will help with this task. 
  • Regular cleaning of your hot tub filter is critical to maintaining water quality. A dirty filter can reduce the effectiveness of hot tub water circulation and heating.
  • Regularly clean the surfaces and waterline of the hot tub to prevent dirt and oils from accumulating. 
  • Also, inspect hot tub components such as the cover, jets, and seals monthly and seasonally for signs of wear or damage and repair them immediately.

Expert Tips and Tricks on Hot Tub Installation

Here are useful and helpful tips from the hot tub experts that can elevate your hot tub experience and ensure a trouble-free installation.

  1. Choose a high-quality, well-insulated cover, as it can reduce heat loss, lower energy costs, and protect your hot tub from debris and weather.
  2. Inspect the hot tub seals and gaskets from time to time for wear and leaks. Replacing them promptly can prevent water damage and costly repairs.
  3. To calculate the total weight of a hot tub with water and people in it, you’ll need to consider the weight of the hot tub itself, the weight of the water, and the combined weight of the occupants. Here’s how you can calculate it:
Expert Tips and Tricks on Hot Tub Installation

  • Check the manufacturer’s specifications or manual for the empty weight of your hot tub. This information is often provided in pounds (lbs) or kilograms (kg).
  • A gallon of water weighs approximately 8.34 pounds (3.78 kg). You’ll need to know the water capacity of your hot tub, which is usually provided in gallons. Multiply the number of gallons by 8.34 to find the weight of the water.
  • You’ll need to estimate the combined weight of the people in the hot tub. 

For example, if your empty hot tub weighs 600 pounds, it can hold 400 gallons of water. You have two people in it, each weighing 150 pounds, the calculation would be as follows:

πŸ–‹ Weight of empty hot tub: 600 lbs

πŸ–‹ Weight of water: 400 gallons x 8.34 lbs/gallon = 3,336 lbs

πŸ–‹ Estimated weight of occupants: 2 people x 150 lbs each = 300 lbs

πŸ–‹ Total weight with water and people: 600 lbs + 3,336 lbs + 300 lbs = 4,236 lbs

4. Check with the delivery service whether the unloading of the hot tub is included in the curbside delivery. It may happen that they will deliver it to you, but you will have to unload it yourself. Therefore, be sure to ask about this issue. 

5. When choosing a location for the hot tub, make sure there will be no trees above it. It will be a β€œlot of fun” to clean up leaves and other dirt that will fall from them.
