Hot Tub Developments Over The Years

By Owen Jones


Hut tubs have been commercially available for about 50 years, so you can guess that the technology has come a long way. In the early days, hot tubs were normally merely a small round wooden tub that was bursting at the seams with over two people in it. They were invariably round in shape and there was very little choice.

The first hot tubs to appear in the States were seen in the 1940's, but they were usually little more that than wooden barrels filled with hot water intended to give a long deep soak. In the 1950's, the idea grew and families started to create or buy hot tubs in order to relax and to alleviate the indications of arthritis. By the mid 1960's, individuals were adding home-manufactured heaters and pumps and very crude versions of the contemporary wooden hot tub were being born.

One early innovator was Roy Jacuzzi who developed and marketed the first hot tub that incorporated swirling water and jets. This whirlpool bath literally began the whole industry in 1968. In the early 1970's, manufacturers started to incorporate more powerful jets into their hot tubs and some manufacturers began making more comfortable designs out of fibreglass and acrylic. The business was taking off big time.

Jacuzzi began to manufacture larger models so that friends or a family could all enjoy the experience together. Most of the modernizations since the late 1970's have been technical, but these technical improvements have been quite significant.

The filters are more readily accessible these days which means that they are more likely to get cleaned out as often as they ought to be in order to prevent the build up of bacteria from decomposing vegetation and hair. This will pollute the water and could pose a health hazard. Not just that, but blocked filters means that the pump has to work harder to circulate the water which means more wear and tear and eventually, more money.

There is a better choice of materials and colours nowadays. Before, the choice was: what type of timber do you want? Now you can still have that option, plus the choice of any colour acrylic you would like as well. Or you can have an acrylic tub inside a wooden (or synthetic wood) exterior or skirt.

The benefits of the synthetic materials are that they last longer, are easier to clean and can be impregnated with a product that kills or wards off bacteria and mould.

The seating arrangement can be customized in modern spas to suit individual bathers. Each seat might have one or more directable jets and the seat itself might be manufactured to a specific height for a certain person or for a specific injury or condition.

The water heating arrangements are a great deal more adaptable as well. Nowadays, the water can be warmed by gas, electricity, your homes central heating system or by solar power, which is a huge improvement if you live in a country that enjoys a great deal of sun.

To top it all off, you can add aromatherapy oils and spa salt crystals to the water by placing them in a drawer like in a dish washer and have them circulated in the water evenly.
