Before you look at the reviews, let’s have a look at different types of outdoor tubs which you can install in your own garden. Having this information will help you single out the type which can serve your needs in a better way.


Types of Outdoor Tubs

There are two types of outdoor tubs which are available in today’s market: Permanent and Portable. Each one of them comes with its own sets of pros and cons and choosing any one of these two types really depends on your personal preference.

Permanent Hot Tubs

As its name suggest, this type of outdoor hot tubs is designed to be installed and fitted at a fixed place. They are not meant to be transported from one place to the other on a frequent basis or kept away when not needed. As a result, they normally come with a heavyweight frame and rigid construction. You will need to have a dedicated space for this either in the garage, pool house, roof top, balcony or gazebo.

Their walls are made of hard material, which may be cement or acrylic, and you have to fix them into the ground or raised platform. They also come at a higher price tag as compared to the portable outdoor tubs so if you are looking for a durable product, one which can serve you for years to come, the permanent hot tub is a better investment.

Portable or Inflatable Hot Tubs


Incorporating a lightweight construction, the portable hot tubs require very little installation. You just have to place them on the ground and connect them to a power outlet. They do require that you use an even floor and remove any rubble or pointy objects on the surface. The best way to avoid any damage to the portable hot tub is to line the floor first with a tarpaulin sheet or pond liner.

Portable hot tubs are mainly tall inflatable pool for adults with built-in pump, water jets, heater and sometimes water filter. Unlike the permanent  option, it is generally very easy to carry the portable hot tubs from one point to the other when deflated. Perfect for the garden deck and patio, it is an affordable option, often a third or less then price of its permanent counterpart.

How to Maintain Hot Tubs

Here are a few tips which can prolong the lifespan of your fixed hot tubs.

1. Cover

When it comes to the hot tub covers, they are an essential item for keeping this product neat and clean. Apart from protecting the tub from external environmental elements, they also make sure that the water – inside the tub, stays fresh for an extended duration of time.

However, it does mean that the cover comes in contact with a number of different harmful elements, including UV rays of the sun, dirt, and debris. It is imperative that you clean the hot tub cover on a consistent basis to stop the build up of moss and mildew.

If it is a plastic sheet or fiber glass cover, purchase a vinyl cleaner and apply this to the top of the cover. Afterward, clean the cover with a soft cloth. Make sure that no amount of vinyl cleaner gets applied on the bottom of the cover or otherwise, it may have a negative effects on the water.

As for the underside of the cover, clean it with a standard garden hose and a soft cloth to remove any build up of mould on the surface. You can also use dish washing or other light detergent for this purpose as it is imperative that you get rid any stains.

Once you’ve thoroughly cleaned the cover, place it under direct sunlight. When you feel that it is properly dried up, cover it up with a vinyl protector.

2. Chemicals

Chemicals play an important role in the regular maintenance of hot tubs. Not only will they provide you with fresh bathing water, but at the same time, they prevent the formation of bacteria and other dangerous organisms.

Before adding new chemicals into your hot tub, it is imperative that you check their existing levels with the help of test strips. Determine the pH levels, calcium hardness, chlorine and bromine with the help of these test strips and only then should you add new chemicals to the tub.

3. Total Alkalinity

Monitor the total alkalinity level, it should be present from anywhere in between 80-120 PPM inside your hot tub. Low alkalinity levels can cause equipment corrosion, thereby reducing the lifespan of your hot tub. If the alkalinity level is too high, this can cause scaling, cloudy and coloured water.

You can check this test strips, a healthy tub should have its spa water pH level between 7.2-7.8. If the test strips indicate that the total alkalinity levels have gone above or below the specified limit, you should add total alkalinity decreaser or increaser accordingly. These granules are based on sodium bisulphate or sodium bicarbonate respectively and need to be added to the tub with its circulation system switched on for half an hour before re-testing the water’s pH level. You can then decide to repeat the process if necessary.

Search for Alkalinity Decreaser or Alkalinity Increaser on Amazon.

4. Chlorine

The chlorine levels shouldn’t exceed beyond 1.5-3 PPM but if you find out any discrepancy with the help of test strips, add 2TSP of chlorine in either granular form or you also can add chlorine tablets.

5. Bromine

When checking for bromine, it is normally used in place of chlorine thanks to its less potent smell. The optimal bromine level, inside your hot tub, varies from 3 – 5 PPM so keep this in mind while using the test strips and top up or water down accordingly.

6. Calcium Hardness

To keep the calcium hardness in check, make sure that you always use soft water inside your outdoor tub and add Calcium Hardness Increaser to the level required. Its optimal level varies as per the tub’s material of construction so check out the instructional manual in order to determine the ideal level of calcium hardness in your own purchase. Use a calcium hardness test strip and calcium hardness increaser appropriately.

7. PH Levels

According to a wide range of experts, it is recommended that the pH level shouldn’t go beyond 7.2 to 7.8 inside a hot tub. It can go above or below that value due to a number of different factors including the improper amount of chlorine, bromine or total alkalinity. This is similar to monitoring the total alkalinity level in your tub.

If the test strips show abnormal pH levels, you can solve this problem by checking the concentration of the the chemicals above or use the alkalinity decreaser or increaser accordingly. A balanced pH level is important for the spa water in your tub.
