EST. 1977Four decades of cold-climate engineering
Built for the coldest nights your garden can throw at it.
Hot tubs, swim spas and saunas designed for Canadian winters — shells pressure-tested against ice, insulation that shrugs off the British damp, and a support team that picks up the phone in English, from a showroom ten minutes from Gatwick.
01 · TESTED TO
-40°C
Cold-Climate Certified
Shells, covers and controls engineered to withstand genuine Canadian winters — the kind of cold that tells you straight away whether a hot tub was built properly.
02 · HEAT RETENTION
72HR
Heat-Recycling Insulation
5″ tapered covers, silver IR-reflective foil on panels and base, high-density shell foam — and a cabinet cavity kept open so motor waste heat warms the air injection, not cold outside air.

§ 02 / OUR STORY
We started in a country where water freezes for six months of the year.
Canadian Spa Company was founded in 1977 on a simple idea: if you're going to build a hot tub, build one that works when you actually need it — in February, at eleven at night, with frost on the cover and snow on the shoulders. That meant engineering for real cold. Full-foam insulation right to the cabinet wall. Shells that flex without cracking. Heaters that climb back to temperature after a minus-twenty overnight.
Four decades on, that same engineering heritage is delivered, installed and serviced from our UK base in Redhill, Surrey — ten minutes from Gatwick. A British winter is hardly the toughest test our spas have ever been designed for, and your garden deserves something that was engineered for worse.
§ 03 / SIGNATURE TECHNOLOGY
GLACIER AO₃P
The cleanest water in the industry, with the fewest chemicals — because our founders learned what clean water looked like from the lakes they grew up on.
STAGE 01
Silver Ions
Continuous low-level sanitation released into the flow. No added odour, no chemical burn.
STAGE 02
Ozone
On-board ozone generator oxidises contaminants on every circulation cycle.
STAGE 03
UV-C Light
Ultraviolet chamber neutralises microorganisms as water passes by — silently, constantly.
STAGE 04
Antimicrobial
Antimicrobial plumbing built into the spa itself — not a spray-on afterthought.
§ 04 / COLD-CLIMATE ENGINEERING
WARMTH THAT STAYS.
Four layers of insulation, designed for Canadian winters. You notice them most when the temperature drops and the bill arrives.
LAYER 01
Tapered Cover
5″ tapering to 3″, rated for heavy snowfall and shaped to shed pooling water. Most competitors run 4″→3″ or 4″→2″. Heat rises, so the cover does the most work.
LAYER 02
IR Reflection
Silver IR-reflective foil on panels and base — like the blanket thrown around a marathon finisher — bouncing cabinet heat back toward the water instead of the garden.
LAYER 03
High-Density Shell
High-density foam bonded to the shell itself — superior insulation per unit of density, applied where the water meets the cabinet.
LAYER 04
Heat-Recycling Cavity
Cabinet cavity kept open on purpose. Motor waste heat stays in the spa and feeds the air injection, instead of pulling freezing outside air into your back.
Why we stopped full-foaming the cabinet
A decade ago we full-foamed the cabinet, the way some competitors still do. On paper it looks thorough. In practice it took away the one thing a cold-climate spa needs most: somewhere for the motor's waste heat to go.
Turn on air injection in a fully-foamed spa and the jets have nowhere to draw air from except the outside. In a Canadian February, that means pumping −15 °C air straight into 38 °C water. You feel it within minutes — the spa goes cold.
Our spas draw air from inside the heated cavity instead. Even with full air injection running, you'll typically lose only 1–2 °C over a 45-minute soak — no compromise between a lively, frothy water flow and a warm one.
