Hot Tub Materials Compared
An honest comparison of the four hot tub shell materials, including the tradeoffs we would want stated if we were the ones buying, and where an aluminum tub is not the right choice.
A wood fired hot tub has no electricity running costs. The main ongoing expenses are firewood and water per use, with minimal annual maintenance costs. For most owners using the tub two to three times per week, total annual running costs sit well below those of a comparable electric spa, with firewood cost varying significantly depending on how it is sourced.
This guide breaks down each cost category honestly so you can plan with confidence.
The best off-grid hot tub works reliably on remote properties: easy installation, efficient heating, strong insulation, and low-maintenance durability. This guide compares aluminum-lined cedar, all-cedar, fibreglass and rectangular models, covering firebox size, insulation quality, and how each performs in cold weather and hard-to-access locations.
A hybrid hot tub brings together the elemental ritual of wood fired heating with the ease of electric heating and built in filtration. Use wood for the full sensory soak, or let electricity maintain temperature, protect against freezing, and keep water clean between uses all year round. The very best of both worlds!
The practical questions people ask before buying: how hot it gets, how long it takes to heat, how well it holds temperature, whether it works in winter, what size to choose, which heating system suits your property, and how delivery actually works.
