At Fix My Hot Tub, we truly understand the joy of relaxing in a hot tub after a long day. But we also know that maintaining a hot tub can come with its fair share of questions and uncertainties. One common question we hear is, “Can I shim my hot tub?”

It’s an important question to consider because the stability and levelness of your hot tub are crucial for both its performance and your safety.

In this blog post, we will provide you with all the information you need to make an informed decision about shimming your hot tub. So, if you’re curious about whether or not shimming is the right solution for your hot tub, keep reading. We have you covered.

Importance of a Stable and Level Hot Tub Foundation

When it comes to enjoying your hot tub, having a stable and level foundation is of utmost importance. Not only does it ensure optimal performance, but it also ensures the safety of everyone who uses it. Without a stable hot tub foundation, you run the risk of damaging your hot tub and potentially causing harm to yourself or others.

Here are a few reasons why a stable and level hot tub foundation is so essential:

Preventing Structural Damage

A hot tub that isn’t sitting on a stable and level surface can lead to structural damage over time. Uneven weight distribution can cause stress on certain areas of the tub (to the frame and shell), leading to:

  • cabinet warping/not sitting correctly
  • frame cracks/twists/lean
  • cracks in the acrylic
  • soft spots in the acrylic

Some of these can’t be repaired, and the hot tub needs to be replaced. Damage caused by an unlevel or uneven surface is never covered under warranty by any hot tub manufacturer.

Optimal Performance

A level foundation ensures that your hot tub operates as intended. When the base is uneven, water may pool in certain areas, making it difficult for jets and filters to function properly. This can result in:

  • poor circulation,
  • reduced heating efficiency,
  • a need to top off your water more regularly (as the “zone” for correct water level shrinks),
  • hot tub drain (when jets splash during filter cycles or heating, the water hits the cover and drips out the side),
  • annoying hot tub use (jets can cause splashing at the surface, which then hits/disturbs bathers), and overall subpar hot tub performance.
  • and overall subpar hot tub performance.

Personal Safety

We can’t stress this enough – a stable and level hot tub foundation is essential for your safety. An unstable base can increase the risk of slips and falls, especially when getting in or out of the tub. Additionally, if the hot tub were to shift due to an uneven foundation, it could cause injury to anyone inside at the time.

As a responsible hot tub owner, it’s your duty to ensure the integrity of the support system of your hot tub at all times. Let’s explore whether shimming is a viable solution if your hot tub is not sitting flat on its foundation.

Can I Shim My Hot Tub? Risks & Drawbacks

If you have noticed that your hot tub is not sitting level on its foundation, you may be wondering if shimming is a viable solution. Shimming involves inserting thin, tapered pieces of material underneath the hot tub to level it out.

While shimming can potentially provide a quick fix, it’s important to consider the possible risks and drawbacks before proceeding.

Risks and Drawbacks

Before deciding to shim your hot tub, it’s essential to understand the potential risks and drawbacks associated with this method. Here are some factors to consider:

  1. Stability Concerns: Shimming may temporarily level your hot tub, but it doesn’t address underlying stability issues. If your hot tub isn’t sitting flat on its foundation due to structural problems or an uneven base, shimming may not provide a long-term solution. It can even exacerbate existing instability, leading to further damage down the line.
  2. Warranty Implications: Most hot tub manufacturers have specific guidelines for the installation and maintenance of their products. Altering the hot tub’s original position by shimming it may void the warranty. It’s advisable to consult the manufacturer’s documentation or talk to a sales expert to understand the implications before proceeding.
  3. Uneven Weight Distribution: Shimming may help level the hot tub, but it can affect weight distribution. Placing additional pressure on certain points of the tub can strain the shell and frame. This can cause leaks or damage compromising both the performance and longevity of your hot tub.

Explore The Alternative Solutions

Before resorting to shimming, it’s worthwhile to consider alternative solutions. Exploring these options allows you to find a more reliable and suitable foundation for your hot tub. Here are some popular alternatives to consider:

  • Adjust the Base: Start by ensuring that the foundation itself is level. This may involve repositioning the hot tub or adjusting the base it sits on. If the base isn’t sturdy, replacing or reinforcing it can help achieve a stable and level surface.
  • Landscape Adjustment: Evaluate the area where your hot tub is installed. If it’s on uneven ground, consider landscaping to create a leveled and stable platform. This can involve removing or adding soil, using pavers or concrete slabs, or creating a raised deck to support the hot tub.
  • Professional Installation: If you’re considering a new hot tub or relocating an existing one, opt for professional installation. This ensures the proper placement and foundation support while adhering to manufacturer recommendations and warranty guidelines.

Ultimately, the best course of action will depend on the specific circumstances of your hot tub and its foundation. Consult with a sales expert or contractor who specializes in hot tub installations to explore the most suitable solution for your needs.

Remember, maintaining a stable and level foundation for your hot tub is essential not only for its optimal performance but also for your safety. Consider the potential risks and drawbacks of shimming, explore alternative options, and consult professionals to make an informed decision.

Considerations for Shimming a Hot Tub

When it comes to shimming your hot tub, there are several important considerations to keep in mind. While shimming can be a temporary fix for a hot tub that is not sitting flat on its foundation, it’s essential to weigh the potential risks and drawbacks before proceeding. Here are some key factors to consider:

1. Stability and Longevity: Shimming may provide a temporary solution for leveling your hot tub, but it is not an ideal long-term fix. Over time, the shims may shift or deteriorate, impacting the stability of your hot tub. This instability can lead to uneven weight distribution and potentially cause damage to the tub and its components.

2. Warranty Implications: Many hot tub manufacturers have specific guidelines regarding the use of shims. Jacuzzi, for example, has a “no shim” policy.

Altering the original foundation or using improper shimming materials may void the warranty. It’s important to consult the manufacturer’s documentation and seek professional guidance before proceeding with any modifications.

3. Consult with Experts: Before deciding to shim your hot tub, it is highly recommended to consult with a sales expert or contractor. They can assess your specific situation and provide valuable insight into the best course of action. Their expertise ensures that proper adjustment is made to protect the structural integrity of your hot tub.

Considering these points before deciding to shim your hot tub will help you make an informed choice. However, remember that shimming should only be considered as a temporary measure and alternative solutions exist which might better suit your needs for a stable and level hot tub foundation.

Best Hot Tub Foundations – 3 Top Options

When it comes to installing a hot tub, choosing the right hot tub foundation is essential for its longevity and performance. There are several options to consider, each with their own advantages and considerations. Here are some of the best foundation options for a hot tub:

1. Synthetic Spa Pads (Good Option)

Synthetic spa pads have gained popularity in recent years due to their convenience and durability. These pads are made from high-density foam or plastic, providing a stable and level surface for your hot tub. These pads can be placed on a smooth, flat, and level surface. Ideally, they will be placed on 6″ of pea gravel.

Some key benefits of using synthetic spa pads include:

  • Easy installation: No need for extensive excavation or construction.
  • Lightweight yet strong: Synthetic spa pads can support the weight of a hot tub while still being easy to maneuver.
  • Excellent drainage: The design of these pads allows for efficient water drainage, helping to protect the base of your hot tub from moisture-related issues.

A drawback is that a base can shift over time or become uneven when the pads are placed on an unprepared site, considering the fact that filled hot tub weighs over 2000 kilograms. Also, the ground may heave during frost, as the site is unprepared.

Pros: quick, easy, cheap
Cons: may shift and require attention

2. Wood Decking with a Concrete Foundation (Better Option)

If you’re looking for a more aesthetically pleasing option, consider installing your hot tub on a wooden deck with a concrete foundation. This combination provides both stability and visual appeal. Key features of this foundation option include:

  • Customizable design: A wood deck can be built in various shapes, sizes, and finishes to match your outdoor space.
  • Enhanced insulation: The addition of a layer of concrete underneath the deck can help insulate the hot tub, preserving heat and energy efficiency.
  • Long-lasting: Properly constructed wooden decks can stand the test of time, adding value to your property.

3. Poured Reinforced Concrete Pads (Recommended/Best Option)

For those seeking the utmost durability and stability, a poured reinforced concrete pad is an excellent choice. Poured reinforced concrete pad with a minimum thickness of 4 inches (10 cm) would work the best!

Here are a few reasons why many hot tub owners opt for this foundation option:

  • Maximum strength: Reinforced concrete pads provide excellent load-bearing capacity and can withstand heavyweights without cracking or sagging.
  • Long-term stability: Concrete pads offer superior durability, ensuring your hot tub remains level and secure over time.
  • Minimal maintenance: Once properly poured and cured, a concrete pad requires minimal upkeep and can last for decades.

When deciding on the best foundation option for your hot tub, consider factors such as your budget, intended usage, and the layout of your outdoor space. It is always recommended to consult with a professional sales expert or contractors who specialize in hot tub installations before making a final decision. They can provide tailored advice based on your specific project requirements and local building codes.

Remember, choosing the right foundation is crucial in providing a stable, level, and enjoyable hot tub experience for years to come.

Take local weather conditions into account when choosing a foundation, and opt for options that can withstand the elements in your area.

3. Assess available space

The size and shape of your available space will determine which foundation options are feasible. Measure the area where you plan to install the hot tub and consider any landscaping or patio features that may impact the layout.

  • Synthetic spa pads (good)
  • Wood decking with a concrete foundation (better)
  • Poured reinforced concrete pads (best)

4. Weigh the pros and cons

Take time to evaluate and compare the advantages and disadvantages of each foundation option based on your specific needs. Consider factors such as cost, durability, maintenance requirements, and aesthetic appeal. It may be helpful to create a list of pros and cons for each option to assist in making an informed decision.

5. Seek professional guidance

Consulting with a sales expert or contractor specializing in hot tub installations is highly recommended. They have the knowledge and experience to assess your needs, evaluate the feasibility of different options, and provide valuable insights that align with local regulations and industry best practices.

Remember, selecting the right foundation for your hot tub is vital for ensuring its stability, longevity, and overall enjoyment.
