Turbo charge your Clearlight infrared sauna by adding one of our optional Full Spectrum Heaters to any Clearlight sauna model. Feel an additional 300 watts of deep penetrating mid, near and far infrared to soothe aching muscles, relax your body and take your sauna session to the next level.


Our door heater is designed to safely and securely plug into a special built-in receptacle in the front of your sauna. Every Jacuzzi sauna has this feature built in at the factory to allow you to take advantage of this and any future upgrades as they are designed.


Full Spectrum Heater measures 24” x 7“ x 4" and mounts on the interior sauna door to provide more healing infrared heat.

Upon Arrival


Errors are costly. Your verification of shipment accuracy can save you time and money. When a shipment arrives please follow this procedure:


  1. Count the total items and compare that to the bill of lading. Then verify item numbers against the packing slip. If there is a discrepancy, note it on the bill of lading before signing for the goods.
  2. Inspect all goods. Check the labels to be certain that they are correct.
  3. If a package is delivered damaged, do not refuse the freight. The package should be opened immediately with the driver present. On the freight bill, specify the exact nature of the damage to the items (scratched, broken, chipped, etc.) The driver should sign your copy of the freight bill.




You may cancel or change your order without penalty up to one business day after submission of the same, unless the order has already shipped after sending you an Order Confirmation and you expressly approve such shipment or we otherwise expedite shipment at your request. A 25% restocking fee plus (for orders already shipped) freight charges will apply to all orders cancelled after this grace period.



You have up to 30 days to return unused items with Clearlight Infrared’s approval for credit or refund. All refunds are subject to a 25% restocking charge. An Returned Material Authorization (RMA) number is required before returning your product. Please contact returns@thesaunasolution.com to receive an RMA number if your item is unopened and still listed on our store.

If you find that our own website has a lower price for the same item you have ordered within three months of your purchase date will refund the difference as well.

To request your partial refund simply e-mail us a link to the same product on our website, or on our competitors website within three months from the date of your order and we will process the credit accordingly. Please email info@thesaunasolution.com.
