What Is In A Pool Closing Kit?
Every pool closing kit will be slightly different. However, they all contain the same core chemicals. These are the non-negotiable components necessary to close a pool. Pool closing kit chemicals include: winterizing powder, pool shock, and stain treatment. We enjoy the In The Swim closing kit because it also has some winter sorb and winter pool floater. These aren’t essential, but they do make the experience better.
What To Look For In A Pool Closing Kit
There are a few rules you can apply to make your pool closing kit experience better. First, make sure you buy a closing kit for your pool’s size in gallons. If you elect to try a cheaper option designed for smaller pools, you won’t get the same chemical ratios. Therefore, you may receive some staining or other consequences in your pool.
Next, for the best possible outcome, don’t buy your pool closing kit too early. We suggest buying your kit 1-2 months before you plan to close your pool. Furthermore, make sure you store the kit’s chemicals in a dry, safe environment.
Lastly, look at the recent reviews of the pool closing kit you plan to purchase. This will ensure that you don’t buy from a manufacturer that’s having supply chain or quality issues. Reading reviews, and recent ones at that, is always a critical step of any buying process.
Best Pool Closing Kits
When you’re looking for the right pool closing kit, you’re really only faced with a few options. Only the larger, more trustworthy pool chemical companies offer complete pool closing kits. Whereas, some niche chemical companies may only sell 1-2 of the components necessary and therefore, don’t offer full closing kits.
This is quite similar to the concept of a pool opening kit. The main faces behind pool opening and closing kits include In The Swim, Doheny’s and RX Clear. Here are the three best pool closing kit bundles available for your pool.






How Much Should Pool Closing Kits Cost?
Pool closing kits aren’t much of a cost consideration. You save a small amount by bundling the chemicals together. However, if you have a pool, you need these ingredients anyway and all closing kits are priced roughly the same. For the sake of comparing apples to apples, we will use a 15,000 gallon pool as the sample size. You can expect to pay $40 – $50 for a 15,000 gallon pool closing kit. On the contrary, if you have a large pool, you can pay around $60 – $70 for a 35,000 gallon pool closing kit.
Prices will vary depending on the size of you pool. Although, unlike other pool products, prices won’t vary much between brands. Pool closing kits are typically sold in bundlings fit for common pool sizes. These include 7,500 – 15,000 – 35,000 – 40,000 gallons of water.

Pool Closing Kit Reviews Summary
If closing your pool sounds like a big hassle, consider a pool service company. Paying someone to close your pool can relieve stress and ensure the correct chemicals are administered. The right time to close your pool can also vary depending on your climate.
Using a pool closing kit, you eliminate the chance of buying the wrong amounts of a chemical. You also rule out missing a critical component to close your pool. As long as you feel comfortable with closing your own pool, a closing kit will make things very easy.
