Stainless Steel Wood-Fired Heater

Wood-fired heaters provide an economic way to enjoy a hot tub: efficient heating, using renewable fuel, and thus environmentally friendly. No worries about longevity as these heaters are made with stainless steel, which resists corrosion despite the outdoor weather and direct contact with water.

  • Made of 304# stainless steel
  • Excellent corrosion resistance
  • Heats water from cold to 38 °C in a couple of hours (depends on the size of the tub, the quality of wood, and the outside temperature)
  • Heat shielded flue for everyone’s safety and protection

Water Pump and Filtration System

This cedar hot tub is also equipped with a water pump that makes heating quicker and more efficient. This hot tub package also includes a filtration system that works hand in hand with the water pump to keep the water clean and protects the pump from debris and dirt. The pump and filtration system are tucked and hidden under the hot tub stairs.

Polystyrene Thermal Covers​

High-Density Polystyrene Thermal Covers

Shym Sauna utilises high-density polyurethane for thermal covers for its effective thermal insulation. HDPE, one of the most effective thermal insulation materials, provides superior heat insulation. This thermal cover also resists damage from long-term exposure to water with its marine-grade vinyl and chlorine construction. This cover kit also includes a safety clip to lock it in place.


High-grade Canadian Western Red Cedar

The wooden components in this kit are all made of high-quality Western Red Cedar. One of the best materials for outdoor saunas and hot tubs, Canadian Western Red Cedar wood is naturally resistant to pests, moisture, and decay. Also, the dark color and aromatic scent of red cedars produce a conducive environment of relaxation.

Stainless Steel Straps and Heater

Stainless Steel Straps and Heater

Faster Heating Time

The pump circulating water from the heater and into the tub improves heating time and allows uniform heating in the hot tub. The circulation also helps to elevate the water temperature as compared to a hot tub setup with no water pumps.
Cleaner Water for Longer Spa Sessions

Cleaner Water for Longer Spa Sessions

With water filtration systems equipped, water is maintained to be free of dirt and debris while being circulated.

Create A Setting For Connection And Relaxation

Building a hot tub or a spa is not about building an appliance, but about creating a space where you build memories and experiences that can make your family closer. A wood-burning hot tub is a very good way to loosen up, converse and enjoy with family and friends.
Create A Setting For Connection And Relaxation


Our outdoor cedar hot tub can be quickly built with its barrel assembly methodology: A base is surrounded by staves that are held up by steel straps, just like a barrel. Assembly can be done in a few hours and can be a DIY project for home improvement.

The package will come with detailed instructions as well as a video guide as an easy step-by-step tutorial you can follow.
