What Should I Do Before My Hot Tub Arrives?

What Should I Do Before My Hot Tub Arrives?

Once you’ve decided to buy a hot tub, there are quite a few jobs to complete to prepare for its arrival.

Your local Caldera Spas dealer can walk you through the process in a step-by-step way and provide detailed pre-delivery instructions that will make the task feel completely manageable. Our goal here is not to answer every detail down to the size of the pea gravel you might use as a base, but to outline the things that you may need to consider.

1. Where will I put my new hot tub?

Many people like the idea of locating their hot tub in a remote area of their property. Generally, though, easy, close access translates to more use. Running electrical wiring away from the house can also be more costly.

Once you’ve decided where to place your hot tub, measure and mark off the area so that you can visualize it there. Is there room to move around the hot tub? Is there easy access and adequate space for steps? It’s very important that there’s room to open and work around the hot tub’s access panel. If that side of the hot tub is placed against a structure, the hot tub’s components won’t be accessible for servicing. Also, consider the view; will you want a privacy fence?

Most of all, is there a wide enough delivery path from the road to the space you’ve chosen? Is there enough vertical clearance between the path and tree limbs or the eaves of the house? You’ll need adequate space for the hot tub to be wheeled in on its side. Remember to include the height of the dolly, too. It’s not unusual for installers to use a crane to put a hot tub into place. Your Caldera Spas dealer can help you connect to the right resources.

2. What’s needed to prepare the site? 

A hot tub can weigh from 2,000 to 8,000 pounds when filled (and even more when you add people), so it needs a suitable base. The area where it will be placed should be leveled and a foundation prepared. A hot tub should not be placed on soil. Instead, it will need a concrete base, a crushed stone or pea gravel base, pavers or a deck with adequate structural support. Again, your dealer can put you in contact with professionals who can do all the necessary site preparation.

3. What about electrical?

Most hot tubs run off 220 volts and will require electrical work by a licensed professional. Some hot tubs can run off of a standard 110 outlet, but in those cases, the heater and pumps cannot be used at the same time. It’s highly recommended that you have the electrical work done so that you can enjoy your hot tub to its full potential.

4. Can I put my hot tub on my existing deck? 

Before your hot tub is placed on a deck, you must make sure the deck is structurally able to support the weight of the filled hot tub and the maximum number of people that it holds. Consult a qualified, licensed professional who can assess your deck and add structural support if necessary. Caldera Spas dealers can refer you to contractors they’ve worked with before.

5. What if I’m adding a new deck? 

Make sure that the new deck plans include a load capacity that will support your spa. Your Caldera Spas dealer can provide you with weight specifications and scale renderings of our hot tubs in PDF and CAD formats to help you and your contractor or deck builder with planning and design.

Need help designing a deck? Caldera Spas also offers a 3D Deck Design Tool, an interactive deck planner that can help you design a deck in a step-by-step approach.

Preparing for the arrival of your hot tub may seem like a lot of work at first, but your Caldera Spas dealer will help you through every stage and provide you with the resources to make the process flow smoothly.

What Can I Do With My Hot Tub Water When It’s Time To Change It?

What Can I Do With My Hot Tub Water When It’s Time To Change It?

There’s a great deal of attention on water conservation and smart water use, especially in areas of the country where rain or snowfall are below normal levels.

Here are some tips to using your old spa water wisely.

The water in your hot tub can be recycled for use around your home, decreasing the amount of fresh water you need.

Here are answers to some common questions when it comes to recycling spa water:

Is Recycled Hot Tub Water Considered the Same As Water from a Tap?

No. Spa water is classified as “gray water,” similar to water from baths, showers and bathroom sinks.

Using gray water serves two purposes:

  1. It can the reduce amount of fresh water needed for some household tasks.
  2. It lessens the amount of water entering the waste treatment system.

Can Water From All Hot Tubs Be Recycled?

Some hot tub brands use salt water systems that may damage lawns or shrubs, so it’s not recommended for use on plants.

Does the Water Need to Be Treated in Any Way Before It’s Used?

Most sources recommend waiting for three days after chemicals were last added to your hot tub, turning off the spa and allowing the water to cool. Chlorine should dissipate quickly, especially if you leave the cover off. After three days, test the water to make sure that the chlorine level is at zero. The pH should be between 7 and 8 to be safe for plants.

How Do I Get The Water From My Hot Tub To Where It’s Needed?

Most portable hot tubs drain by gravity from a valve at the bottom of the spa that can connect to a garden hose. Using the hose, you can apply the water where it’s needed. However, it only works if you’re level with the hot tub or downhill from it. You can always collect water to be recycled in buckets that are easily moved to areas of use.

You can also purchase an inexpensive submersible pump for $50 to $100 (make sure it connects to a garden hose where the water comes out or has an adapter). With it, you can pump water into storage barrels or apply it directly to the task at hand.

What Are Some of the Best Uses for Recycled Hot Tub Water?

Recycled hot tub water can be used in a variety of creative ways, such as…

  • Water the lawn, shrubs, ornamentals, flowers and trees. It’s best to use it on well-established plants. Do not use it on edible plants.
  • Wash your car.
  • Wash your patio furniture, grill, lawn mower and other outdoor equipment.
  • Wash out your garbage cans.
  • Rinse down the patio and driveway.
  • Use it to flush toilets, pouring it directly into the bowl rather than the tank.
  • Store it for later use in barrels or clean trash cans.

Is It Safe to Use Recycled Spa Water on Vegetables and Other Edible Plants?

We do not recommend using your old spa water on your vegetable garden.

Are There Restrictions Governing How I Recycle Water?

Potentially, yes. All recycled water uses are ultimately governed by local jurisdictions, and those take precedence over any of the above suggestions.

After using your spa’s water for months to treat tired muscles, relieve pain and help you rejuvenate, you can potentially get even more use from that water. And that makes your hot tub one the most efficient water users in your home.


As we learn more and more about water conservation efforts, we’d like to hear how you’re taking action. Are you already conserving or recycling water in your home? Would you make the effort to use recycled hot tub water for decorative plants that aren’t getting enough moisture?

We’re also very interested in what other uses you can think of for your recycled spa water. Please leave us a comment so others can take advantage of your ideas. Thank you!
