There are a few pros of placing a fire-heated hot tub directly on grass, although it is generally not recommended. Some of these advantages include:

  1. Cost savings: Installing a hot tub on grass can be a more cost-effective option compared to other base materials, as it doesn’t require additional expenses for creating a concrete pad, wooden deck, or purchasing a hot tub pad or mat.
  2. Easy installation: Placing the hot tub directly on grass is relatively simple and can be done with minimal tools and equipment, making it a more accessible option for some individuals.
  3. Natural appearance: A hot tub placed on grass can blend more seamlessly into the surrounding landscape, creating a more organic, visually appealing setting.
  4. Temporary placement: If you plan on moving the hot tub to a different location or are considering a more permanent base in the future, placing it on grass can be a temporary solution.

However, it is essential to weigh these pros against the cons, which include ground instability, poor drainage, damage to the lawn, increased risk of pests, and insufficient insulation. In most cases, it is advisable to invest in a more suitable base material to ensure the long-term performance, safety, and enjoyment of your fire-heated hot tub.


Placing a fire-heated hot tub directly on grass may have several disadvantages:

  1. Ground instability: Grass and soil can shift and settle over time, leading to an uneven surface, which can cause your hot tub to become unlevel. This can put strain on the structure, potentially leading to leaks, cracks, or other damage.
  2. Poor drainage: Grass does not provide adequate drainage for the water around the hot tub. Excess water can lead to muddy or soggy areas, causing issues with accessing and maintaining the hot tub, as well as creating an unsanitary environment.
  3. Damage to the lawn: The weight of the hot tub, especially when filled with water, can cause damage to the grass and soil underneath. Over time, this can lead to dead patches, compaction, and poor grass growth.
  4. Increased risk of pests: Placing a hot tub directly on grass can attract insects and other pests that may be drawn to the warm, moist environment. This can cause discomfort to users and potential damage to the hot tub structure or its components.
  5. Insufficient insulation: Grass does not provide the same level of insulation and heat retention as other base materials like concrete or hot tub pads. This may result in increased heat loss and higher energy costs to maintain the desired water temperature.

To avoid these issues, it is generally recommended to use a more suitable base material like concrete, a hot tub pad, or a properly constructed wooden or composite deck when installing a fire-heated hot tub.

Better Options for Fire-Heated Hot Tub Placement

While placing a fire-heated hot tub directly on grass may have its allure, there are alternative options that provide better support, longevity, and overall ease of maintenance. Let’s explore some popular choices that can enhance your hot tub experience:

  1. Concrete Pad: A concrete pad is a durable, stable, and long-lasting base for your hot tub. With a professionally installed concrete pad, you’ll have a level surface that can handle the weight and heat of a fire-heated hot tub. This option also reduces the risk of pests and drainage issues, ensuring your hot tub remains in optimal condition.
  2. Hot Tub Pad or Mat: Hot tub pads or mats are designed specifically for supporting hot tubs. They are made of heavy-duty materials that provide a sturdy, level, and slip-resistant surface. These pads or mats can be easily installed, require minimal maintenance, and can be relocated if needed. Additionally, they offer better protection against pests and drainage issues than grass.
  3. Crushed Stone or Gravel: Crushed stone or gravel can be an excellent alternative to placing your hot tub directly on grass. By using these materials, you can create a level, stable, and well-draining base that will support the weight of the hot tub and improve its longevity. With proper installation and maintenance, a crushed stone or gravel base can minimize the risk of pests and drainage issues while offering a visually appealing aesthetic.
  4. Deck Installation: Installing a hot tub on a deck can provide a luxurious and elevated look to your backyard. A properly designed and reinforced deck can support the weight of a fire-heated hot tub while offering an aesthetically pleasing and functional space. Be sure to consult with a professional to ensure your deck can handle the additional load and heat generated by your hot tub.

In conclusion, while placing a fire-heated hot tub directly on grass may seem tempting, there are better options available that will offer improved stability, longevity, and overall satisfaction. By considering alternatives like concrete pads, hot tub pads or mats, crushed stone, or a reinforced deck, you can create the perfect foundation for your hot tub and enhance your backyard experience.


In summary, placing a fire-heated hot tub directly on grass has its pros and cons, with some benefits being cost-effectiveness and a natural aesthetic. However, the drawbacks include potential damage to the grass, instability, and drainage issues. For a better hot tub experience, consider alternative placement options such as concrete pads, hot tub pads or mats, crushed stone, or a reinforced deck. These options provide improved stability, longevity, and overall satisfaction, enhancing your backyard hot tub experience while mitigating the risks associated with grass placement.
