The hot tub maintenance and service life | Kirami - Warmer feelings
Get your hot tub cleaned up for summer

Q: What is the service life of the hot tub?

A: The service life of plastic and aluminium tubs is more than 10 years, but the wooden parts (panels) age/wear over time. The service life of wooden tubs is approximately 5–10 years, depending on how well it is maintained (washing, oiling and good ventilation). 

Q: Are plastic or aluminium hot tubs easier to keep clean than wooden models?

A: Plastic and aluminium tubs are easier to clean, as dirt and impurities come off more easily from their smooth inner surfaces. 

Q: How should I maintain the inner surface of the hot tub?

A: We recommend regularly washing the inner surface with detergent (such as Kirami Biopesu), rinsing it with water and drying it thoroughly. The inner surface of a wooden tub requires more thorough cleaning than plastic and aluminium tubs. However, take care not to scrub the inner surfaces too vigorously in order to avoid scratches. 

Q: Can I treat the inner surface of a wooden hot tub with oil?

A: We do not recommend treating the inner surface of a wooden tub with oil or other similar substances, as they dissolve into the bathwater when the water is heated. The outer panels can be treated with various wood oils or stains, both water and solvent-dilutable. In other words, you can use almost any wood treating products sold at hardware stores. 

Q: How should I maintain the outer surface of the hot tub?

A: Stained, Thermowood and spruce surfaces can be treated with wood oil, provided that they do not form a layer that could damage the panels as the wood swells and shrinks. For Thermowood and stained spruce panels, you can use Teknos Woodex Aqua wood oil with a suitable shade of brown. Composite panels only need to be washed every once in a while. Red cedar panels can be treated with paraffin oil. When treating the tub panels, you can remove the outer hoops or cover them with adhesive tape during treatment, immediately removing any splashes or runoffs. 

Q: Why does Thermowood not shrink and become leaky?

A: Thermowood swells and shrinks considerably less than untreated wood. Therefore, it does not become leaky as easily as conventional spruce tubs. Due to the stability of the material, certain spots have been sealed with silicone. 

Q: My wooden hot tub is leaking. What should I do?

A: Hot tubs made of Thermowood may leak if left unused for an extended period of time or when used for the first time. This is perfectly normal, and the leaking will subside over time. When used on a regular basis, the hot tub becomes watertight. Knots in the wood may leak for a long time.

Hot tubs made of untreated spruce are subject to significant shrinkage and must therefore be swollen with water after periods of unuse.

If a tub with plastic inner surfaces is leaking, check the heater, outlet valve and other possible lead-throughs and joints and tighten or reattach them carefully. If these measures do not solve the problem, check how low the water surface of the tub decreases due to the leak and contact our customer service. The easiest way to contact us is by email: The phone number for our technical support is +358 (0) 10 574 2171. 

Q: Why am I unable to remove the rubber plug from the outlet valve? 

A: The rubber plug may get stuck on the outlet valve if it has been tightened for a long time. It the plug is stuck, we recommend loosening the threads and giving the plug some time to regain its shape and loosen up before the removal. You can prevent the plug from getting stuck with regular cleaning and keeping it loose/untightened when the tub is not being used. 

Q: How do I know how much chlorine I should use in the bathwater?

A: You can find dosage instructions for chlorine in the package labels and in the separate instructions of our starter kit. 

Q: Why is plastic a good material choice for the hot tub?

A: Plastic is a homogeneous and wear-resistant material. Plastic has a dirt-repellent surface, enabling quick and easy cleaning. You can also clean it with a pressure washer. Plastic requires no maintenance, withstands time, is UV-protected and can be used in any weather. It is environmentally friendly and recyclable.  

Q: How does the hot tub filter work?

A: Kirami offers two filter options: a light filter and a sand filter.  

The operating principle of the light filter is that water is first sucked through a coarse filter floating on the surface, from where it is transferred into a submerged fibre filter cartridge. A pump on the bottom of the device pumps the filtered water back into the tub. 

The operating principle of the sand filter is that water is sucked out of the tub with a pump and transferred with pressure through the filtering material inside the filter tank, cleaning the water. For filtering material, you can use conventional  filter sand or Kirami filter fibre.

Filters mix the water in the tub when used. Do not use a filter while bathing. Filters only remove mechanical dirt, while bacteria can be controlled with chemicals.
