What our customers are saying
Shopping with Shasta was an excellent experience. I followed a link from an email from Shasta for a salt cell for my pool, which I needed. They advertised an open box deal which was hundres of dollars less expensive than anywhere else I could find the equivalent part for online.
I accidentlh placed an order for the part to pick up at the wrong location. Communicating through email, Zachary and Chuck quickly resolved the problem and changed the location to the location closer to my home.
I've also shopped for pool deck paint from Shasta. Not only was the price better than anywhere else I could find online, the product was available quickly from my store.

FAQ
Our expert staff answers customer's most asked questions.
Are there discounts on Open Box products?
Yes, we offer discounts on Open Box items. However, these prices are often too low to advertise online as they fall below Minimum Advertised Price (MAP) guidelines. Contact us directly for the best deals on Open Box products.
Can I pick up my order at any time?
Orders can be picked up during our operational hours. You'll receive an email when your order is ready for pickup.
Should I cover my spa or pool with a custom spa cover or solar pool cover if I am heating my pool?
Yes, it is advisable to cover your pool when heating it. Failure to do so allows generated heat to escape, causing the heater to work harder and resulting in higher heating costs. Consider using a custom spa cover or solar pool cover to optimize the efficiency of your heating system.
