Importance of Under Surface of Hot Tub
The importance of putting something under an inflatable hot tub for several reasons. First, the hot tub can be quite heavy, especially when it is filled with water and people. This weight can put stress on the surface it is placed on, causing damage and even permanent indentations. By placing a material under the hot tub, the weight can be distributed evenly, reducing the stress on the surface and preventing damage.
Second, a material under the hot tub can also provide insulation, which can help to keep the water warm for longer. Without insulation, the hot tub may lose heat quickly which will make it less enjoyable to use.
Third, a material under the hot tub can provide a level and stable base for the hot tub. If the surface is uneven, the hot tub may wobble. This will also make it unsafe and uncomfortable to use. A stable base can also help to prevent leaks and prolong the life of the hot tub.
That is why, placing a material under an inflatable hot tub can help to protect the surface it is placed on, provide insulation, and create a stable and level base for the hot tub.
6 Materials to Put Under Your Inflatable Hot Tub
When it comes to what to put under an inflatable hot tub, there are a variety of materials that can be used to create a stable and safe surface. Each material has its own advantages and disadvantages. So it’s important to choose the one that best fits your needs and situation. Here are some of the most common materials used to put under an inflatable hot tub, along with their pros and cons:
1. Sand
Using sand as a base for an inflatable hot tub can be a good option for a few reasons. Firstly, sand can provide a stable and level foundation for the hot tub, which can help prevent it from shifting or wobbling. Also, sand can help distribute the weight of the hot tub more evenly, which can reduce the risk of damage to the ground beneath it.
Pros:
- Relatively inexpensive and easy to obtain.
- Used to create a level surface, even on uneven terrain.
- Helps to distribute the weight of the hot tub, preventing damage to the surface it is placed on.
Cons:
- Shift over time, requiring frequent re-leveling.
- Messy and difficult to clean up if it gets into the hot tub.
- May not be suitable for all climates, as it can retain moisture and freeze in colder temperatures.
2. Gravel
Gravel is another common material used for creating a base for an inflatable hot tub. Using gravel as a base for an inflatable hot tub is another option that can provide a stable and level foundation. It can also help with drainage, which can be beneficial if you live in an area with heavy rainfall or if you plan to use the hot tub outdoors.
Pros:
- Easy to obtain and relatively inexpensive.
- Helps to distribute the weight of the hot tub, preventing damage to the surface it is placed on.
- Provides good drainage, which can be helpful if you live in an area with heavy rainfall.
Cons:
- Sharp or jagged gravel can puncture the bottom of the hot tub, so it’s important to choose a smooth variety.
- Shift over time and require frequent re-leveling.
- May be difficult to remove if you decide to move the hot tub.
3. Foam Mats
Foam mats are a popular choice for creating a cushioned and slip-resistant surface around an inflatable hot tub. Using foam mats as a base for an inflatable hot tub can be a good option if you are looking for a lightweight and easy-to-move solution. Foam mats can also provide some insulation, which can help keep the water in the hot tub warmer for longer.
Pros:
- Provide a cushioned surface that can be comfortable to walk on.
- Are easy to install and can be cut to fit the shape and size of your hot tub.
- Can help prevent slips and falls, which is especially important around wet surfaces.
Cons:
- May not provide enough stability on its own and should be used in conjunction with other materials, like sand or gravel.
- Expensive compared to other options.
- Retains moisture, which can be a problem in humid or wet climates.
4. Rubber Pavers
Rubber pavers are another popular option for creating a slip-resistant surface around an inflatable hot tub. Using rubber pavers as a base for an inflatable hot tub can be a good option if you’re looking for a durable and long-lasting solution. Rubber pavers are designed to withstand heavy weight and foot traffic, which makes them a good choice for supporting a hot tub.
Pros:
- Provide a slip-resistant surface that can help prevent falls.
- Easy to install and can be cut to fit the shape and size of your hot tub.
- Durable and can withstand heavy foot traffic.
Cons:
- Can be more expensive than other options.
- May not be suitable for all climates, as they can become brittle in extremely cold temperatures.
5. Wood Pallets
Wood pallets are a popular option for creating a stable and level surface for an inflatable hot tub. Using wood pallets as a base for an inflatable hot tub is not recommended. While it may seem like a cheap and easy solution.
Pros:
- Relatively inexpensive and easy to obtain.
- Create a level surface even on uneven terrain.
- Sturdy and can withstand heavy weight.
Cons:
- Difficult to move once they are in place.
- Becomes damaged over time and may need to be replaced.
6. CosySpa Hot Tub Flooring Protector
If you own a hot tub, you know how important it is to protect your investment. One key way to do this is by using a hot tub pad. The CosySpa Hot tub flooring protector is a foam ground sheet designed to go underneath your hot tub. Unlike some other options, which come in square or rectangular tiles, this one is cut into a circular shape. It’s also thicker than some other options, at ½” thickness. This means it provides a greater level of protection and insulation for your hot tub.
Pros:
- The foam material used in this hot tub pad feels good under your feet. This can be especially important if you spend a lot of time in your hot tub.
- The circular shape of this hot tub pad makes it easy to install. It’s also lightweight, so you can move it around as needed.
- As we mentioned earlier, hot tub pads are designed to protect the bottom of your tub from scratches, punctures, and other damage. The CosySpa Hot tub flooring protector does an excellent job of this.
Cons:
- As this hot tub pad is made of foam, it doesn’t allow for much airflow. This can lead to moisture buildup underneath your hot tub, which could potentially cause mold or other issues.
- While the CosySpa Hot tub flooring protector is reasonably priced, it is more expensive than some other hot tub pad options on the market.
DIY Hot Tub Base
There are a few steps you can follow to create a solid base for your hot tub. These steps can create a sturdy base for your hot tub that will provide a level and stable surface for years to come.
Step 1: Choose the location
The first step is to choose the location where you want to place the hot tub. Make sure the spot is level and has adequate drainage. Also, make sure the location is easily accessible for filling and draining the hot tub.
Step 2: Measure and mark the area
Measure the dimensions of your hot tub and mark the area where you want to build the base.
Step 3: Prepare the site
Remove any grass, rocks, or other debris from the area. Make sure the area is level and compacted. You can use a plate compactor to compact the soil.
Step 4: Build a frame
Use 4×4 pressure-treated lumber to build a frame that matches the dimensions of the hot tub. Secure the corners with screws and use stakes to anchor the frame to the ground.
Step 5: Install a weed barrier
Lay down a weed barrier over the compacted soil inside the frame. This will prevent weeds from growing up through the base.
Step 6: Pour a concrete slab
Pour a concrete slab inside the frame, making sure it’s level and smooth. You can use a concrete mixer or hire a concrete contractor to pour the slab for you.
Step 7: Allow the concrete to cure
Allow the concrete to cure for at least 48 hours before placing the hot tub on it.
Step 8: Install the hot tub
With the base complete and the concrete fully cured, you can now install the hot tub on top of the slab.
