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 marine-grade aluminum interior solves every structural problem that has always limited traditional cedar hot tubs: leaking, bacterial growth, poor heat retention, and difficulty getting to remote locations. It does this while keeping everything worth keeping about the wood fired soaking experience, including the Canadian Western Red Cedar exterior, the firebox, and the simplicity of use.
This guide covers where AlumiTubs came from, why marine-grade aluminum was the right material choice, and how that decision shapes the tub's performance in practice.
Most conventional hot tubs have a significant environmental footprint: continuous electrical standby consumption, heavy chemical use that enters waterways when drained, non-recyclable materials, and short lifespans that accelerate the replacement cycle. A sustainably designed tub addresses each of these at the design level, not just through better habits. This guide covers what genuinely sustainable hot tub design looks like, and how to use any tub with a lighter footprint.
Sustainability is not a single feature. It is a series of considered decisions about energy, materials, water, and longevity, compounded across the life of the product.
The AlumiTub Performs Better. Unrivalled Quality. Obsessive Engineering. Built to Endure. Uniquely designed and meticulously crafted, its not your average wood fired hot tub. Merging form and function, it was designed in 2001 with the beauty and timelessness of wooden hot tubs, made only more enduring and functional thanks to its marine grade aluminum foundation.
Three materials, one of them milled from a fallen cedar down the road. How AlumiTubs sources marine-grade aluminum, Canadian Western Red Cedar and stainless steel, and the design decisions that make a tub gentler on the planet across decades rather than years.
