Durability: The chosen stones must be able to withstand the weight of the spa and any people who will be using it. It is recommended that you use flat stones with a smooth surface that can distribute the weight evenly.

Porosity: You want to avoid porous stones as they may absorb water and cause damage over time. Non-porous or low porosity stones such as granite or basalt are ideal for this purpose.

Safety: Slip-resistant qualities in your chosen stone should also be considered when placing a hot tub on top of it. Stepping onto wet, slippery rocks could lead to an accident causing permanent injury – so make sure you choose non-slippery ones!

Certain types of stone have their own unique properties that offer added benefits such as natural insulation or heat retention capabilities.

Aesthetics: Finally, consideration should be given to how well these stones blend with outdoor surroundings and decor – especially if placed where visiting individuals are expected!

Consider investing in one if you intend having several hot tubs within suitable sections distributed evenly showing off different designs under each basin.

Size and Shape

The best size for these types of stones is usually around 6-8 inches in diameter. This size provides plenty of stability for most home spas while still being easy enough to work with during installation.

In terms of shape, round or slightly oval-shaped rocks work well because they can help distribute the weight of the spa evenly over a larger area. Additionally, flat-bottomed stones can also be used as long as they are thick enough to provide sufficient support.

It’s important to note that when selecting stones for this purpose, it’s crucial to choose ones that aren’t susceptible to cracking or crumbling due to weather exposure or other external factors.

One good option might be natural river rocks which tend to hold up well over time.

In addition, adding sand or gravel underneath your spa also provides an additional layer of insulation and cushioning from the ground’s natural movement. The added insulation helps retain heat within your hot tub while keeping energy costs low.

Positioning the Stones

Selecting the right stones to use under a spa is crucial as they need to be durable and able to withstand the weight of the spa. The two primary types of stones used are concrete pavers and natural stone, both having their advantages.

Concrete Pavers:

Concrete pavers are an affordable option that offers durability and versatility in terms of design options. They come in different sizes, shapes, colors, and textures, allowing you to customize your look. Be sure to choose a thickness that matches or exceeds that recommended for your specific hot tub model.

Natural Stone:

A popular choice for outdoor spas is natural stone such as granite or flagstone because it provides a timeless look with unique character. Natural stone can support heavier loads than pavers but may require more maintenance due to its porous nature.

“It’s important not just to consider what type of stones you want under your spa but also how you position them. Placing them on level ground will ensure proper balance and prevent any cracks or damage from occurring. “

No matter which type of material you select, it must be installed correctly using polymeric sand or mortar. Another way to add stability is by placing a layer of crushed rock underneath the stone bed; this will help distribute the weight evenly across all surfaces while preventing sinkage over time.

Ultimately, selecting suitable stones will provide essential support for your home spa while adding aesthetic value to your backyard oasis. Take careful consideration when choosing your materials so that they meet not only functionally but also visually enhancing elements within your landscape design goals.

Securing the Stones in Place

When it comes to installing a spa, choosing the right stones to use underneath is crucial. The stones used will help with proper drainage and ensure that your spa stays level.

One type of stone commonly used under a spa is crushed gravel or pea gravel. This type of stone provides good drainage to prevent water buildup and promotes stability for the spa above. However, be cautious not to use sharp-edged rocks as they may puncture or damage your spa’s base.

If you’re looking for an eco-friendly option, consider using recycled rubber pavers instead of natural stone. These pavers are lightweight but still sturdy enough to support the weight of most hot tubs. Plus, they offer excellent slip-resistant properties so you can step safely onto them even when they’re wet.

“Remember to always create a stable foundation when laying stones beneath your spa. “

No matter what kind of stone you choose, make sure it is leveled properly before placing the spa on top. Otherwise, pressure points could cause problems down the line like uneven heating or early wear-and-tear on components. In conclusion, selecting appropriate types of stones for places under a Spa is important due to its durability and safety concerns. Always opt for ones that promote good drainage systems and provide a secure base both above ground and underground.
