Hot Tub Journal

Clean, safe, long-lasting tub water comes from preventing problems before they start, not from correcting them after. Balanced water chemistry reduces the amount of sanitizer needed. A simple preventative routine, guided by regular test strip readings, keeps water comfortable for bathers and easier on the materials. The result is water you change quarterly rather than weekly, using far less chemical input at every stage.

This guide covers the parameters, the treatment sequence, the products, how to care for the materials, and how to use and conserve water responsibly.

The first year with a cedar hot tub involves a genuine learning curve. The tub goes through a break-in period as the cedar settles and releases tannins, the water care routine takes a few cycles to become instinctive, and the first winter asks for attention new owners often do not anticipate. Month by month, what is normal and what needs action.

Filling and emptying a hot tub at a property with no tap. Lake, river, rainwater and hauled water, what each means for water care, and how filtration changes the calculation.

Dimensions, filled weights, clearances and service access for architects and designers specifying an AlumiTub. Everything needed at drawing stage, in one place.

Hot tub water has four key parameters: alkalinity, pH, calcium hardness, and sanitizer. Each affects the others, so the order you balance them in matters. Test regularly, adjust gradually, and the water largely looks after itself. The goal is not to add more chemicals when things go wrong. It is to keep conditions stable enough that nothing goes wrong in the first place.

This guide covers what each parameter does, what range to target, how to test, and how to build a routine that keeps water safe without overcomplicating it.

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.

Everything an off-grid hot tub has to get right: getting it there without a crane, filling it from a lake, a well, a tank or the ocean, heating it with no electricity, holding heat through real winters, and how the main tub types compare on each. Then what to verify before buying any of them.
