Better insulation means you'll pay less for electricity to keep the spa hot. Although today's spas require less maintenance than in the past, they do require some regular upkeep. Depending on the type of chemicals selected, spa owners will have to check the pH level at least once a week. Other weekly maintenance may include adding a few chemicals. Tub owners should also clean the filter once a month and occasionally wipe down the skirting.
Most retailers suggest changing the spa's water once every three to six months.
Changing the water should only take about an hour and the hot tub can be filled with water from a garden hose. Another major consideration is the warranty. Check the length of the warranty and the items covered. Bennett and Richie said potential customers should look at a spa as long-term investment. You can expect 20-plus years of use out of a Hot Spring spa.
