How To Level A Hot Tub On Concrete

How to Level a Hot Tub on Concrete: A Step-by-Step Guide

So, you've finally got your hot tub! Congratulations! Now comes the crucial step of ensuring it's perfectly level. A slightly uneven hot tub can lead to a variety of problems, from uneven water distribution and premature wear and tear on the pumps to, frankly, just an uncomfortable soaking experience. This guide will walk you through how to level a hot tub on a concrete base, ensuring a relaxing and enjoyable experience for years to come.

Assessing Your Concrete Base

Before you even think about shimming, you need to thoroughly assess your concrete slab. Is it truly level? Even minor imperfections can become magnified with the weight of a hot tub.

Tools You'll Need:

• Level: A long level (at least 4 feet) is ideal. A shorter level will give you less accurate readings.
• Measuring Tape: For accurate measurements.
• Shims: These are crucial. Wood shims (various thicknesses) are readily available at most home improvement stores. Consider using plastic shims for added longevity and resistance to moisture.
• Hammer: For tapping the shims into place.
• Optional: Concrete sealant/caulk: To further secure and seal any gaps left after levelling.
• Optional: Plumb Bob: For extra precision, especially on larger hot tubs.

Checking for Level:

1. Clean the surface: Remove any debris or loose material from the concrete.
2. Place the level: Place the level in multiple locations across the concrete slab, both lengthwise and widthwise. Check for variances in the level reading.
3. Note inconsistencies: Make a note of which areas are high and which are low. Even small discrepancies (more than 1/8 inch) need addressing.

Leveling Your Hot Tub

Once you've assessed the concrete's levelness, you can start the levelling process. This is where the shims come in.

The Shimming Process:

1. Start with the lowest point: Focus on the lowest point of your concrete slab first. Add shims underneath the hot tub feet in that area to bring it closer to level.
2. Work in increments: Don't try to level everything at once. Add shims in small increments, checking the level frequently. It's much easier to add shims than to remove them.
3. Check all directions: After adjusting one area, check the level in all directions to ensure you haven't created new inconsistencies.
4. Use multiple shims: Often, it's better to use multiple thinner shims rather than one thick shim to distribute the weight more evenly.
5. Fill gaps: Once leveled, you can use concrete sealant/caulk to fill any gaps between the shims and the concrete. This adds stability and helps prevent water from seeping beneath the hot tub.

Maintaining Level

Even after initial leveling, it's important to periodically check the levelness of your hot tub. Over time, the ground might shift slightly, requiring minor adjustments.

Troubleshooting

• Uneven concrete: If the concrete is extremely uneven, shimming may not be the ideal solution. Consider consulting a concrete professional to address the foundation issue.
• Hot tub feet: Ensure the hot tub feet are in good condition and adjusted properly. Damaged or malfunctioning feet will hinder the levelling process.
• Heavy items: Avoid placing heavy items near your hot tub. This could influence the levelling.

By following these steps, you can ensure your hot tub is perfectly level, creating a relaxing and enjoyable hot tubbing experience. Remember, patience and precision are key to success! Enjoy your soak!
