Hot Tub Journal

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.

How sacrificial anodes protect an aluminum hot tub, why magnesium rather than zinc, how often to replace them, where to source them, and the four things anodes cannot fix.

The four numbers that matter in an aluminum hot tub, why calcium hardness is the one most owners miss, what order to balance in, and which common spa products are not compatible.

Aluminum doesn't rust the way steel does, but it is a metal and it reacts under specific conditions. What those conditions are, why soft water is the one most owners don't expect, and how the tub is built to handle them.

Three different things get called pitting, and they have different causes. What the deposits actually are, why soft water is the one most owners don't expect, and how a tub already showing them gets put right.

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.

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.
