With the start of the winter maintenance season in British Columbia and Alberta, Trevi Pools & Spas is reminding hot tub owners in Kelowna and Calgary that a spa kept running through the cold months still needs regular water testing, a secure cover and safe soaking habits. The guidance applies to home spa owners in any cold-climate region.

Many homeowners close their pools in the fall but keep their spas running through the winter. Colder weather can make routine checks easy to put off, but water chemistry keeps changing whenever a spa is in use, so the routine still matters.

Trevi recommends starting with water balance. In its guidance for residential pool and hot tub owners, the U.S. Centers for Disease Control and Prevention recommends a free chlorine level of at least 3 parts per million in hot tubs and a pH between 7.0 and 7.8. The same guidance advises owners to test chlorine and pH at least twice a day, and more often when several people use the water, and notes that DPD test kits give more accurate results than test strips. The CDC also recommends against using cyanuric acid, a chlorine stabilizer, in hot tubs. For spas treated with bromine, the CDC's hot tub safety guidance lists a range of 4 to 8 parts per million.

Spa owners who are unsure about their water chemistry can bring a water sample to the Kelowna or Calgary store for free testing. Both stores carry spa chemicals and testing supplies, so owners can make the adjustments a test calls for.

Safety guidance also applies in winter. The CDC's hot tub safety guidance says water should not be warmer than 104 degrees Fahrenheit, or 40 degrees Celsius. It advises against drinking alcohol before or during hot tub use, recommends that children under 5 not use hot tubs and advises people who are pregnant to talk to a healthcare provider first. It also notes that a properly treated hot tub has little odour and that a strong chemical smell indicates a problem.

The U.S. Consumer Product Safety Commission advises spa owners to always use a locked safety cover when the spa is not in use and to keep young children away from spas unless an adult is supervising them at all times.

Some Trevi customers use a cold plunge after time in the spa, and the Western Canada stores sell one. A 2025 systematic review in PLOS One examined 11 randomized trials of cold-water immersion in healthy adults. The trials tested cold water alone, not hot-and-cold routines or any specific product, so the review does not establish that contrast routines or Trevi's cold plunge are safe or effective. Anyone with heart, circulation or other health concerns should consult a healthcare professional first.

Trevi Pools & Spas recommends that spa owners set a regular testing routine at the start of the season rather than waiting for cloudy water or odour to signal a problem.

The Kelowna and Calgary stores are run by Trevi's Western Canada franchise, which says it has served homeowners in British Columbia and Alberta for about 10 years. The stores sell Trevi spas and take spa orders in-store. The spas themselves are made by the Trevi brand, which is headquartered in Mirabel, Quebec. According to the company, its spas are built at its own Lacus plant in Lachute, Quebec, and its Dynasty plant in Tennessee

Trevi Pools & Spas provides pool and spa products, water testing, maintenance supplies and seasonal services. Its Kelowna location serves homeowners throughout the Central Okanagan, and its Calgary location serves customers in Calgary and surrounding communities.
