How to turn Hot Tub into Pool – Step-by-Step!

Spread the love

Can you turn an above ground pool into a hot tub? Yes, but it will look very do-it-yourself and will consume a lot of energy.

A hot tub is essentially a large bathtub equipped with temperature control, air blowers, and a variety of water jets. Additionally, seats.

You can easily mount seats if you can locate them. A set of shaped plastic chairs secured with weights should suffice.

Nozzles for air and water can be purchased as spare parts from vendors of jacuzzis and similar pipe systems.

Supply air to the air jets via a compressor, and water to the water jets via a submersible pump – I purchased one for my solar heating array, but you’ll need a fairly sturdy pump. Unless you have access to adjustable units, I’d recommend making both water and air flow adjustable via valves. Compressors should be housed in a soundproof enclosure because they make an unbelievably loud racket.

Then add a water heater of some sort. You’ll need muscle, as the above ground pool loses quite a bit of heat, even when covered at night and insulated on the sides (hint, hint). Not to mock you, but if you Google “redneck pool heater,” you’ll find something like this:

While this method is crude, heating a pool to hot tub temperatures requires some oomph and time.

Now, notably, the air, circulation, and temperature all contribute to the fact that things will grow in it, so consult a jacuzzi expert about the chemicals to use. I’m not sure that standard pool chemicals will suffice.

It’s going to look like a 1950s Russian battle tank, and it’s going to cost a fortune in spare parts before you’re done… however, it is absolutely possible.

Spas have temperatures ranging from 99 to 104 degrees, whereas pools have temperatures between 80 and 85 degrees.

Creating a spa does not necessitate the purchase of a new heating system. Indeed, the majority of pools include a spa mode.

Due to the high temperature of the water, the pH balance changes frequently. Additionally, spas require weekly alkalinity testing and balancing.

Always check the water level following each use, as bathers lose over a liter of body fluids while in a spa.

Total annual maintenance costs for a chlorine system are approximately $800. Additionally, you will need to install on-scale resisters due to the fact that warm water has a tendency to dissolve calcium and magnesium.

These two minerals can deposit small amounts of material in your pool.


A spa, like a pool, requires regular maintenance. Frequently check and adjust the chemical levels in your spa with a test strip.

The majority of test strips provide six-in-one results for alkalinity, calcium, chlorine, pH, and bromine.

Keep the spa water running while adding the chemicals to ensure that the chemicals are propelled into the water by the jets.

Due to the fact that a spa and a pool operate on the same principles, they must also use the same chemicals.

However, due to the salt chlorinator, a salt-water pool requires a higher level of maintenance. In salt-water hot tubs, the chlorinator maintains a constant flow of chlorine, which is kinder to the skin.

Due to the fact that salt is corrosive at elevated temperatures, saltwater spas require frequent replacement of metal components and internal components.


When converting your pool to a spa, you will require a large number of jets. Jets aid in the circulation of warm water and provide a soothing massage bubble effect. Jets are available with a variety of different nozzle and plumbing configurations.

As a result, you should select a jet that generates gentle, relaxing pressure. High-pressure jets produce a greater volume of water, which may be uncomfortable for some swimmers.

Consider purchasing smaller jets for spas that cater to small children and seniors. Jets of varying sizes can help seniors with aching joints and bones.

Soft tissue jets have a softer feel than standard jets, which provides a more comforting experience. A therapeutic massage will be provided by the soft tissue massage nozzle.

Plastic and stainless steel jets are available. Due to their aesthetic and anti-corrosive properties, pool professionals recommend stainless steel jets.

To ensure that jets operate efficiently, remove and clean jets once a year. Additionally, you should soak them in a mild vinegar solution to assist with mineral buildup.

For optimal jet performance, check your filter periodically to determine if it requires replacement.


Spas have elevated the ancient practice of hydrotherapy to new heights. Spas use extremely hot water to treat muscle and joint stiffness, inflammatory diseases, and even spinal pain.

Spas also benefit your mental health; ten minutes in a spa helps alleviate daily stress. If you have insomnia, hot tubs can help you sleep better by relaxing your body.

Additionally, hot tubs can assist in lowering blood pressure!


Homeowners who already have a pool frequently consider adding a spa. The cost of installing an attached spa is approximately ,000. Summer is rapidly approaching, and the prospect of gazing at a construction site is repulsive.

The best option is to convert your pool into a spa. Because the spa is connected to the same plumbing and mechanical systems as your pool, installation will be inexpensive.

Due to the high temperatures of the water, adding a spa will allow you to use your pool well beyond the summer months.
