What is available?

There are a large number of hot tubs on the market today. Everything from simple inexpensive wooden hot tubs to luxurious spa baths with massage functions. Therefore, prices can vary from EUR 1 000 to more than EUR 20 000. Deciding on what to choose is a question of knowing what you need and how high you appreciate comfort. Read our tips here! How many will use the hot tub, and how often is it normally used? A large hot tub requires more water, a longer heating time and higher energy costs. This mostly goes for hot tubs. When considering costs, it is important to realise that buying the wrong item is also expensive.

Bathing 1-2 times per week?

The cheapest hot tub with a wood burning heater can be enough if you don't bathe so often, don't need to think about water usage and have your own supply of fire wood. In practice this means that you fill the hot tub with water, heat it and then empty it after use. It is also possible to install filtration so that the same water can then be used, in combination with chemicals, for a longer time. If a hot tub is not used very often, it is especially important to think about the choice of material. Otherwise leakage problems can easily lead to a situation where it feels like too much trouble to use the hot tub at all.

Bathe whenever you want

If you simply want to bathe often, without having to spend too much time taking care of your investment, then consider an alternative with automatic heating and filtration. The water is then changed 4-5 times per year, and the hot tub is always ready for use. For this purpose we have developed our Polar models, which you can read about here.

Choice of material and risk of leakage

Traditional hot tubs are often made of normal pine, spruce, larch etc. that shrinks a lot when dry and swells in water. A normal problem then is large leakages if the hot tub has been standing without water for some time. Some manufacturers therefore recommend keeping water in the hot tub even when it is not being used. This often leads to bad water hygiene. Note this, and ask the manufacturer to guarantee that the hot tub won't start leaking even during dry periods.

Guarantee against leakages!

A hot tub made of special quality heat treated wood (used by SpaDealers) is not sensitive to dry weather. This is because the material is already so dry during assembly that it won't shrink any more. However, it can still expand a little and tighten any small leakages that may occur during the first time of use. Therefore no water needs to be kept in the hot tub in order to prevent leakages. As a result, maintenance is much easier and water hygiene is better. The weight of heat treated wood is also much less. There is no resin left and the insulation effect is 30% better.

Ecologically right!

Only steam and high temperatures are used during the drying process, which ensures a natural material without any environmentally dangerous chemicals. The colour is brown all the way through the wood. Although the initial disadvantage is a higher price, this price is really very reasonable after all the benefits are taken into consideration.

Water hygiene

Care is needed to ensure that the same water is not used for a long time, unless it is treated and filtrated regularly. Otherwise there is a great risk that bacteria will start to grow and cause a health risk. This is of course, regardless of which material a bath or hot tub is made of. Many people think that plastic and stainless steel, for example, will provide protection from bacteria, which is completely wrong. Filtration is supposed to remove particles, but has no affect on preventing the growth of bacteria or removing them. The only safe way to ensure protection from bacteria is to use cleaning detergents.

Outdoor hot tub in continuous use

A spa bath can have, for example, a massage function with a varying number of adjustable jets. It can also contain a stereo, TV etc. Perhaps these are things you don't associate with a relaxing bath? The seats are also usually ergonomically formed with both better and worse results. One other thing that is typical for spa baths are that they are insulated in order to withstand cold weather and be economical in use. This works well as long as nothing breaks down. If a circulation pump breaks down or if the power is cut, the result can be expensive repairs due to frozen pipes, pump etc. This is because most spabaths have the pipes and pump inside an uninsulated service opening. The same goes for the walls and base. The "shell" itself where the water is contained, is usually well insulated.

Outdoor bath for Nordic conditions

SpaDealers' Polar models are totally insulated bubble- /massage baths with advanced functions and solutions, developed as a result of our wide experience and knowledge. Polar AquaKing can be said to be something between a hot tub and a spa bath. It has an insulated cover, bubble system, automatic filtration, electrical heating and an interior plastic coating (TubCoat) fitted as standard. Among other things, a massage function through jet nozzles is available as an optional extra. During construction, great consideration has been paid to the climatic variations in the Nordic countries. Everything is well insulated and the Polar can withstand temperatures as low as -30°. The model can even manage to survive up to 24 hours without problems during a power cut. The effective insulation also makes energy use low. For 4 hour filtration and maintenance heating, only 4.5 kWh is used per day when the water temperature is set at 37°. Polar is an outside bath for users placing high requirements on functionality, comfort and nice handmade woodwork.

Inner surface treatment

TubCoat is a 2-compound polyurethane-based transparent elastic material that can be "painted" onto the inside of the hot tub to provide an easy-to-clean durable plastic surface. The material can be used for all types of wood and hot tubs. We especially recommend its use whenever a filtration system is used and the same water is to be used over a long period of time, for example with the Polar. TubCoat is also recommended for normal wooden hot tubs where leakage problems are common. TubCoat has made it possible to have a hot tub outside due to the advantages that plastic provides concerning maintenance. Since the plastic is transparent, your hot tub will still keep the genuine feel of wood and look nice.
