Are Hot Tubs High Maintenance? 

One of the most common questions we hear at Island Spas and Pools is some version of: “I’d love a hot tub, but are they a lot of work?” It’s a fair question — and the honest answer is no, not really. A few minutes a few times a week is genuinely all it takes when you know what you’re doing. To help clear up the confusion, we put together this guide specifically for homeowners in Brunswick and New Hanover County, Oak Island, Southport, Wilmington and the surrounding area — because living on the coast does come with a few unique considerations worth knowing about.

Water Chemistry: Simpler Than It Sounds

Keeping your water balanced is the most important part of hot tub ownership — and it’s also the part that intimidates people most before they actually do it. In practice, it comes down to testing three things: pH (you’re aiming for 7.2–7.8), total alkalinity (80–120 ppm), and sanitizer levels. That’s it. Test strips make this a two-minute process. We provide test strips with every spa we sell and walk every new owner through exactly what to look for before we leave the driveway.

For most homeowners, testing two to three times per week keeps everything balanced without any drama. If you notice the water getting cloudy, a shock treatment — adding a dose of chlorine or oxidizer to break down organics — usually clears it up quickly.

Need to restock chemicals or test strips? We carry everything you need in our parts and chemicals shop at our Oak Island showroom.

Filter Care: A Quick Rinse Goes a Long Way

Your filters are doing the quiet work of keeping your water clear every day. A quick rinse with a garden hose every two weeks removes accumulated debris and keeps water flowing properly through the system. Once a month, a deeper soak in filter cleaning solution dissolves the oils and buildup a rinse alone won’t catch. Plan to replace your filters every 12 to 18 months depending on how often the spa is used.

If you’d rather hand off filter care entirely, that’s exactly what our maintenance service plan is designed for. More on that below.

Draining and Refilling: Once Every Few Months

Even with perfect chemistry, dissolved solids build up in hot tub water over time. Draining, scrubbing the shell, and refilling with fresh water every three to four months resets everything and makes chemical balancing easier going forward. 

What’s Different About Hot Tub Maintenance on the Coast

The North Carolina coast does have some coastal-specific things worth noting when it comes to general hot tub maintenance.

Salt Air and Your Cabinet

Salt air accelerates wear on outdoor surfaces, and hot tub cabinets are no exception. A periodic rinse of the exterior with fresh water — especially after storms or heavy wind — goes a long way. A UV protectant applied to the cabinet panels once or twice a year helps maintain the finish over time.

This is one reason we’re selective about the brands we carry. The cabinets on our PDC Spas, Cal Spas, and Jacuzzi DreamMaker models are all built for outdoor durability — but proper care still extends their lifespan significantly.

Humidity and Water Balance

Brunswick County and New Hanover’s humidity, especially in summer, means your water chemistry can shift faster than it would in a drier climate. Testing two to three times a week rather than once is particularly important here. It also makes your cover more valuable than ever — a properly fitting cover keeps humidity out and heat in, which improves both chemical stability and energy efficiency.

Year-Round Use Means Year-Round Filter Care

In most of the country, hot tubs get a break in warmer months when people switch to pools. Here in coastal North Carolina, most homeowners use their spas year-round — which is one of the genuine advantages of this climate. It also means your filters are working harder than average. If you’re using your spa four or more times a week, consider rinsing filters weekly rather than every two weeks, and replace them on the shorter end of the 12-to-18-month range.

Storm Season Prep

Before a tropical storm, make sure your cover is latched and secured, and turn the spa off at the breaker for significant weather events. After the storm passes, test your water before getting back in — wind and rain can throw off chemical balance quickly.

When to Handle It Yourself vs. Call Us

Most routine maintenance is genuinely manageable on your own. But there are situations where a call saves time, money, and frustration.

Handle yourself: water testing and chemical balancing, filter rinsing and cleaning, draining and refilling, wiping down the shell and cabinet.

Call us: water that won’t balance despite correct chemical additions, unusual noises from the pump or jets, error codes on the control panel, cloudy water that persists after a drain and refill, any leaks.

Because we’re local, we can get out to customers in Brunswick and New Hanover County quickly when something needs attention. You can learn more about what we offer on our services page — from routine maintenance visits to repairs and water care.

Rather Just Hand It Off? We Do That Too.

Our maintenance service plan is designed for homeowners who want the benefits of a hot tub without thinking about the upkeep. We handle water testing, chemical balancing, filter care, and regular inspections on a schedule that works for you. It’s a popular option for vacation rental owners, seasonal residents, and anyone who values their weekends.

As one of our recent customers put it: “The service plan is well worth the money.” We’d agree.
