Product Description

The SunnyTent Round Pool Dome (Size L+) is an upgraded alternative to traditional pool covers and solar pool covers. Designed for both above ground pool covers and inground pool cover applications, this innovative pool dome captures the sun’s heat to naturally warm your swimming water without any energy costs. From spring through fall, enjoy a longer swimming season with warmer, cleaner water and minimal maintenance.

Why Choose the SunnyTent Pool Dome?

  • Solar Heating – Functions as a solar pool cover, raising water temperature naturally and reducing heating costs.
  • All-Season Versatility – Keeps your pool water clean and warm for months, and can be reinforced for winter with the optional cross pole set.
  • Cleaner Water, Less Effort – Protects against leaves, dirt, and debris, making it one of the most effective pool covers for above ground pools and inground pools.
  • Extra Layer of Protection – Covers your pool to help reduce unsupervised access by children or pets, providing peace of mind.
  • Durable European Quality – Made from eight-layer PE foil for superior sun (UV) resistance and long-lasting strength.
  • Lightweight Yet Strong – Flexible fiberglass poles provide a sturdy, easy-to-handle structure.

Perfect Fit for Extra-Large Pools
The SunnyTent Round Size L+ is designed to fit pools up to ø 16 ft, making it ideal for larger medium-sized swimming pools. It combines the natural warming benefits of a solar pool cover with the full protection of a pool dome, giving your backyard a stylish, functional, and long-lasting solution.

Winter-Ready Option
For year-round use, the SunnyTent can be reinforced with the optional cross pole set to withstand wind up to 5 Bft. Always follow the provided instructions for winter setup.

Installation & Use

The SunnyTent Pool Dome Round (Size L+ – ø 17.7 ft.) has a ground diameter of approximately 17.7 ft and a top height of around 102 inches, making it ideal for both above ground pool covers and inground pool cover applications. Two people can assemble the SunnyTent Round L+ in about one hour. For daily use, partially opening the dome takes just one adult a few seconds, while fully opening or closing it requires two adults and roughly a minute.

If installing on a hard surface, we recommend using our hard surface set for secure anchoring. The SunnyTent Round Size L+ fits larger pools — whether above ground or inground — and works with round, square, or rectangular pool shapes.

Its versatility extends beyond swimming pools: it can also be used to cover hot tubs, in-ground trampolines, sandpits, and vegetable gardens, providing year-round weather protection and helping reduce unsupervised access by children or pets.

Built to last, the SunnyTent comes with a 2-year full warranty on all parts. Unsure if your pool will fit under the SunnyTent Size L+? Use our online sizing calculator to check.

Save Hundreds of Dollars in Energy Costs

The SunnyTent works the same as a greenhouse. In a horticultural greenhouse, the inside temperature in the period mentioned above is usually much higher than the outside temperature. A number of factors determine how quickly the water heats up. The more the sun shines, the warmer it gets inside the SunnyTent and the faster the water heats up. The amount of water and its initial temperature is also important.

Frequently Asked Questions

What are the advantages of a SunnyTent pool dome?

By installing a SunnyTent pool dome around your pool, you can enjoy a range of benefits. Here's why it's a great addition to your pool:

  • Warm and Clean Water: The pool dome helps maintain warm and clean water. It harnesses the warmth of UV rays to keep the pool water at a comfortable temperature.

  • Energy Efficiency: With the pool dome in place, you can significantly reduce your energy costs. It minimizes heat loss and reduces the need for pool heaters, saving you money.

  • Reduced Water Usage: Since the pool water remains clean and free from debris, you won't need to change it as frequently. This not only saves water but also reduces the effort required for pool maintenance.

  • Enhanced Water Quality: You can keep your pool water exceptionally clean by using chlorine and regularly monitoring water quality, ensuring a safe and pleasant swimming experience.

In summary, a SunnyTent pool dome offers a cost-effective and eco-friendly solution to keep your pool water warm and clean, all while saving you money on energy and water expenses.

How do I set up the SunnyTent?

Setting up the pool dome varies slightly depending on the size of your SunnyTent. Larger sizes, such as the XL, have additional poles and specific instructions for double-pole placement. For detailed instructions tailored to your specific pool dome size, please refer to our instruction videos and manuals. In general, the following steps apply to all pool dome sizes:

  1. Place Locking Pegs: Arrange two locking pegs in a straight line, ensuring they are spaced at the correct distance from each other. This distance may vary based on your specific tent size.
  2. Replace Locking Pegs with Hinged Anchors: Replace the two locking pegs with hinged anchors, driving them straight into the ground until the pins make contact with the ground.
  3. Unfold the Tent Foil: Lay out the tent foil on the ground. Insert the poles into the connectors, ensuring they fit into the corresponding tunnels for each section of the foil.
  4. Position the SunnyTent: Place the SunnyTent between the two hinged anchors. Set the pole sets on the pins of the hinged anchor, making sure they are fully placed over the pins.
  5. Raise the SunnyTent: Lift the SunnyTent upward until it forms a complete circle. To evenly distribute the tent foil between the poles, gently shake the tent both horizontally and vertically.
  6. Secure with Twisting Pegs: Use twisting pegs to firmly secure the tent in place. Be cautious to avoid damaging the foil during this step.
  7. Attach the Guy Line: Attach the guy line and open the SunnyTent.

For detailed instructions tailored to your specific pool dome size, please consult our instruction videos and manuals to ensure a successful setup.
