Made From Top Quality Canadian Red Cedar

Our Electric Tubs are made of top quality Canadian Red Cedar which is a close cousin to the traditional cypress wood used in Japan. Red Cedar has the distinct advantage of being naturally resilient to decay and bacteria. It also is known for its high insulating value. The pleasant aromatherapy of cedar heightens the experience! Our tubs use an architectural stainless steel strap system which allows the tub to naturally expand and contract with out worrying about the wood splitting.

On-Site Assembly Process

All our hot tubs kits are designed with the DIY customer in mind. Customers with basic handyperson skills can assemble the wood hot tub body in 3-4 hours over a two-day period. We recommend spreading the assembly over two days to allow the liner "set" overnight before finishing the interior componets of the tub. A typical install would be 2 hours on Day 1, set the liner overnight and another 2 hours on Day 2. In order to assemble the main tub body, you will need a basic set of tools including a level, a measuring tape, a Phillips-head driver drill, a pair of adjustable crescent wrenches, vise grips, and a mallet. We also recommend having a rachet strap on hand to assist with tightening the bands. 

For our electric hot tubs, we recommend our customers work with a professional plumber and electrian to set up their water heating and circulation system. More experienced DIY customers have the option to plumb the system themselves, however this is a more challenging and time consuming step. Regardless of your skill level, you should always work with a licensed electrician on the electrical connection. 

Hot Tub Liner Included As Standard

Our 100% virgin vinyl hot tub liner is designed specially to fit with a minimal appearance that preserves the rustic and timeless beauty of a cedar tub. There are numerous benefits asscoiated with a vinyl liner. Firstly, lined cedar tubs are much easier to clean, sanitize and maintain. The liner eliminates a host of issues like leaking, tannin leaching and wood-rot. Liners also make the tub more comfortable to sit in, as there will be no rough edges or splinters. Another important benefit of the liner is that it provides the option of adding a layer of high-performance insulation between the liner and wood. The insulation more than doubles the R-value of wood alone, meaning your water will stay warmer much longer.

Our liners are constructed from 100% Virgin Vinyl, custom designed and computer cut for your hot tub. Formulated to fight off mold, mildew, the fading effects of the sunlight, heat and chemicals. 

Please note, reflective insulation and insulation tape is not included and should be sourced locally.

Starting in 2022, the hot tub liner must be used to prevent leaks. Previously, some customers chose to use their hot tub without the liner as they prefered the all-wood aesthetic. Due to a change in our stave design, tubs can no longer be used unlined. Using the tub without a liner will result in leaks.

Electric Heater Kit

The primary components of our electric hot tub system (the heater and circulation pump) are individually UL listed. However, the Redwood Outdoors electric hot tub heating system is not UL listed as a complete kit. You should review state and local laws and building codes prior to purchasing, as your locality may require that pool and hot tub equipment be UL listed as a complete unit.


We ship our cedar hot tubs to everywhere in the United States to eco hot tub lovers who enjoy a relaxing soak in the full presence of nature!
