This 5 person capacity hot tub is our premium model. It includes a wood fired stove that is made from 304 stainless steel, that can heat the hot tub to the perfect temperature within a 4 - 6 hour time period.

The precision made hot tub components are made from high grade Canadian Red Cedar wood. We select the highest quality cedar wood for it’s proven resistance against rot and insects.

All of our internal heater tubs come complete with a fence to help protect against accidentally bumping into the stove or stove pipe, a fence shelf for drinks or towels, a hose adapted drain kit, galvanized chimney with cap, and an ash scoop.

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


We ship our wood fired hot tubs to everywhere in the United States to eco hot tub lovers who enjoy a relaxing soak, off the grid and in the full presence of nature!

  • You'll love it & some details you'll want to know

    Sep 21st 2020



    We chose to give the internal stove tub a 4 star for one main reason: We found that it does not heat at a rate that you read about online. We've seen 20-30degrees per hour,... once the fire is well established I have observed maybe a good 12-15 degrees per hour. That is a fully stoked stove, full of hardwood or softwood. SO.. to bring some 55 degree water up 50 degrees to a comfortable tub temp , we have not been able to accomplish yet in under 5 hours or thereabouts. And keep in mind, we are not novice wood stove users. 90% of our winter heat source is a wood stove in our home. Other than that here are some things you will want to know about the product itself. #1 Likely because of covid... it took us 3 entire months to receive our tub. Bummer. But worth the wait. #2. The spark arrestor spot welded onto the top of the chimney is of poor design. After 1 single fire, it was 75% clogged with soot. Our second fire would not even vent properly. Had to keep the lid off the fire for it to vent. I removed the spark arrestor with a pair of tin snips and it will now vent properly. #3. Chimney could use a damper. I am considering installing one on my own. If you had one, you could contain the heat much better, and probably heat faster... BUT, perhaps manufacturer does not recommend. I haven't consulted them yet. #4 The directions you are given on the website, are barely close to what actually arrives in terms of hardware/chime joists. The directions for installation were clearly drawn up by someone who was uninformed as to what the company actually ships. And there were outright errors in the directions when it came to spacing for chime joists. No clear direction on how tight to make your steel bands. Lots of incidents where fasteners are not correct length for what you need... very much ,." here's your tub,.. here's some general guidelines for how to install it... call us if you need anything. " Redwood made themselves available for help while assembling, which is nice.. but what would be nicer is if they updated their manual. #5 Sold as a 5 person. I suppose if you were just sitting next to each other with half your bodies out of the water, its a 5 person,.. but in reality its 4 at the most comfortably. And take it a step further, its a 2 person if you want to kinda lay back stretch your feet out under the bench in front of you, submerge your body up to your neck like we all do when sitting in a hot tub when its cold out. I had considered getting a 5x4 and now wish I had, as for the most part its just the two of us using the tub. Cool product. LOVE that it doesn't have any jets or parts and pieces that will fail in a few years. I wonder if the external tub would have been the better bet because you'd have more space,.. and it seems this one doesn't heat as fast as youd think, which is part of the reason we chose it. All in all I do like it, looking back on what I know now, maybe we would have chosen a different size and external.. FYI ours took a week to fully seal. 4/5 because it does not heat as quick as you think.

    I wasn't sure which tub I wanted, but after talking to Mary, she helped me choose the 5 person internal stove, and I couldn't be happier with it!
