As the temperatures begin to drop and the first signs of winter appear, hot tub owners face an important seasonal task: winterizing their spa. Properly winterizing your hot tub ensures it survives the harsh conditions of freezing weather without damage, so it's ready to go when spring returns. Whether you plan to shut down your spa for the winter or continue using it during the colder months, having the right supplies on hand is crucial. In this guide, we’ll explore the 10 must-have supplies to winter-proof your spa effectively and safely.
1. Hot Tub Cover
A high-quality, insulated hot tub cover is arguably the most important item when preparing for winter. A tight-fitting cover not only keeps out snow, ice, and debris but also helps retain heat, saving on energy costs if you keep your spa running. Look for a cover with thick insulation, a vapor barrier, and sturdy locking straps to keep everything secure during winter storms.
2. Cover Cap or Spa Cover Protector
In addition to your standard cover, consider a spa cover cap or protector. This is a weather-resistant layer that goes over your hot above ground pools tub cover to shield it from rain, snow, and UV rays, which can cause deterioration over time. It’s especially useful in areas with heavy snowfall or frequent storms, adding another layer of protection.
3. Non-Toxic Antifreeze for Spas
If you're planning to drain and shut down your hot tub for the winter, non-toxic antifreeze is essential. This specially formulated antifreeze is designed for use in hot tub plumbing and will prevent any remaining water from freezing, expanding, and potentially cracking your pipes and fittings. Be sure to use only antifreeze made for spas and not automotive products, which are toxic and unsafe for this purpose.
4. Wet/Dry Vacuum or Shop Vac
A wet/dry vacuum helps you remove every last drop of water from your hot tub’s plumbing lines, jets, and filter housing—critical steps in preventing freeze damage. Even small amounts of water left in the lines can expand during freezing temperatures and cause costly damage. A shop vac can also be used to blow out lines in addition to sucking water out.
5. Spa Line Cleaner
Before draining your hot tub, it's important to clean the internal plumbing lines with a specialized spa line cleaner. Over time, body oils, lotions, and other residues build up inside the pipes. These contaminants can cause odors, bacteria growth, or gunk buildup if left to sit unused all winter. A line flush product will clean out these residues and prepare your spa for storage or ongoing winter use.
6. pH Balancers and Water Treatment Chemicals
If you plan to keep your hot tub running during the winter, maintaining proper water chemistry is more important than ever. Cold weather can lead to imbalanced water and increased strain on your equipment. Stock up on pH increaser, pH decreaser, alkalinity balancer, and sanitizers like chlorine or bromine. Regularly test your water and keep it balanced to avoid scale buildup and equipment wear.
7. Thermal Blanket or Floating Blanket
A floating thermal blanket adds another layer of insulation by sitting directly on the water’s surface under your hot tub cover. This reduces heat loss and evaporation, helping to maintain water temperature and reduce the workload on your spa heater. It’s a cost-effective solution to improve energy efficiency during the winter.
8. Jet and Pipe Plug Kit
For those fully winterizing and draining their hot tubs, a jet and pipe plug kit is essential. These plugs seal off individual jets and plumbing lines after the water has been drained and blown out. This added precaution helps prevent water from re-entering the lines, reducing the risk of freeze damage.
9. Filter Cleaner and Extra Filters
Before winter hits, give your filters a deep clean using a specialized filter cleaner. Dirty filters restrict water flow and can cause your pump to work harder than necessary. It's also a good idea to have an extra set of filters on hand so you can swap them out during the season without having to wait for a replacement. Clean filters are essential for energy efficiency and water quality, especially in cold weather.
10. Hot Tub Insulation Blanket or Skirt
An insulation blanket or skirt wraps around the base of your hot tub cabinet and adds another layer of protection against the cold. This helps prevent heat loss through the cabinet and minimizes the chance of your equipment freezing. Some spa owners also use foam boards or custom panels to insulate the spa’s underside if their model allows for it.
Final Thoughts
Winter-proofing your spa isn’t just about protecting your investment—it’s also about ensuring safety, efficiency, and peace of mind throughout the colder months. Whether you’re enjoying a warm soak under the snowy sky or preparing to shut it down until spring, using these 10 must-have supplies for hot tub winterization will keep your spa in top shape and ready for whatever the season brings.
