Maintenance hot tub water - Use and maintenance - Isbjørn Hot Tubs

Maintenance hot tub water

During a meeting with a sales advisor, we will discuss the maintenance of the water for your Hot Tub in detail. This has to do with the fact that the water in a Hot Tub will become dirty much faster than, for example, a swimming pool as a result of the high bath temperature of approximately 38-40 degrees Celsius.

If you enjoy a warm Hot Tub, a lot of body substances and fats will soon end up in the water. As a result, the water will look dull or cloudy after 2 uses. A second important factor is the bacteria (algae) that will grow with warm water and plenty of sunlight. This makes the water slimy on the wall side and shows a slightly light green color in the bath.

Do you need a filter or not?

Are you using the tub privately or for public purposes?;
How often will you be using the Hot Tub?;

If you mainly use the Tub for public purposes (B&B, hotel guests), we advise you to change the water after every customer / guest. Tenants of an accommodation will usually not want to use the same water from the previous tenants.

If you use the Tub privately on an irregular basis or at most a few times a month, a filter installation is not immediately necessary and it can often be easier and cheaper to change the water weekly. For example, refresh on Fridays if you want to enjoy the weekend. Without a filter installation, you should take into account that you will have to change the water every week.

If you use the Tub privately on a regular basis, for example during the week, it may be advisable to purchase a filter installation. With a filter / UV installation + (chlorine-free!) granulate supplied by us, you can usually use the same water for 2 months.

The use of chlorine is not allowed in a Hot Tub if the Tub is heated with a wood stove, chlorine and aluminum and some stainless steel do not mix. The warranty on a heater lapses if products that contain chlorine are used. Instead of chlorine, we always advise you to work with a filter with a UV lamp in combination with chlorine-free purification granulate.

Whether you need a filter installation is determined by the following factors:

Standard with Isbjørn filter feedthroughs

We know from experience that many customers cannot yet estimate how often they will use a Hot Tub in the future. They also dread the extra additional costs of a filter installation. For that reason, all Isbjørn Hot Tubs are already fitted with filter feed-throughs in the wall side as standard. If, after a while, you still want to purchase a filter installation, it can be connected in no time. If it is certain that the hot tub should be as basic as possible, we can also omit the transits.

What customers say

R. van der Jagt

Our new hot tub has been in place for a few months now and we are very satisfied. This started with delivery and installation. With us he had to go over the roof. This was not a problem, because the hot tub was delivered neatly packaged on a pallet. Once on the ground it was just a matter of removing the foil and tilting it and it was standing. Installing the heater and filter was also a matter of attaching hoses, turning and firing. We have already spent wonderful hours in it. Both in the hot summer and now in the cold under the starry sky.

Bas and Agnes

I would like to thank you very much for thinking along and delivering the hot tub. The finish and appearance in our garden is more than expected! For now, the neighbors can watch (later we'll blind this corner), but everyone is jealous! Since the delivery last Saturday there hasn't been a day that we haven't enjoyed the tub. Especially with this warm weather, daily heating is not necessary, which results in a refreshing bath every day. We are therefore very pleased that we were able to submit all our questions and wishes to Isbjørn and Woodmex before purchasing this eye-catcher.


Very satisfied with our Isbjorn hot tub. The large heater heats the tub quickly. In the beginning, be careful not to heat too hard so that it gets too hot. All in all, it is wonderful to enjoy and also super cozy with the whole family. Well advised and nice to see the manufacture.

Finally started installing the hot tub today. We couldn't wait to sit in it for a while. And thanks for the warm hats.
