How to Level a Hot Tub on a Concrete Patio

If you’re looking to level a hot tub on your concrete patio, this guide is here to help. You’ll need the right tools and materials on hand as well as some patience for the job. After ensuring your hot tub is level, use additional leveling blocks to make sure it stays securely in place. With a few simple steps, you’ll be able to level the hot tub with ease. So grab your laser level and read on to find out exactly how to get it done.

Tools and Materials Required

When leveling a hot tub on a concrete patio, it is important to have the right tools and materials to ensure the job is done properly.

Before getting started with the project, you’ll need to make sure you have the following items at hand:

  • Measuring level with a laser level
  • Prop leveling blocks
  • Power drill
  • Drill bits
  • Screwdriver
  • Screws
  • Hex wrench
  • Leveling wedges

The laser level is important because it will allow you to ensure your hot tub is level on the concrete patio. The prop leveling blocks will be used to help level the hot tub. A power drill, drill bits and screws will be used to secure the blocks to the ground. A screwdriver, hex wrench and leveling wedges may be needed for adjusting the blocks for a perfectly level surface.

Having all the necessary tools and materials on hand before starting the project will make the job much easier and more successful in the end.

Measuring Level with a Laser Level

Using a laser level is an easy and accurate way to ensure the hot tub is level on the patio. Start by placing the laser level on one side of the hot tub and turn it on. Make sure the bubble level on the laser level is set to the zero mark and that the laser is projecting a level line of light across the entire hot tub. For best results, move the laser level around, moving it from side to side, to ensure the hot tub is level across the length. Once you are confident the hot tub is level, make a few marks along the laser level line, every few inches or so across the hot tub.

You can also measure the level of the hot tub with a 4-foot level. Place the level on the surface of the hot tub and check the bubble level indicator. If it reads level, then the tub is level. If not, adjust the blocks as needed.

Finally, if desired, you can triple check the accuracy of your work by setting an allowance line on the patio surface. An allowance line will help you ensure that the hot tub is level on even an uneven patio. To create an allowance line, mark two points a certain distance apart. Place the tip of the level at the first point and make a line perpendicular to the first. Then do the same for the second point, connecting the two with a line. This line should run across the length of the hot tub, showing you the actual level of the patio surface. If you find the hot tub still isn’t level, then adjust the blocks accordingly.

Prop Leveling Blocks

Prop leveling blocks help to level a hot tub on a concrete patio by creating an even surface for the hot tub to rest on. They can be placed under the hot tub’s legs in order to help level the tub when it is resting on an uneven patio surface. Leveling blocks should be chosen that fit securely under the legs of the hot tub and can also be adjusted to be raised or lowered to create the even surface needed for the hot tub to rest on. There are different types of prop leveling blocks available to accommodate different hot tub sizes and weights. It is imperative to ensure the blocks chosen are strong and durable enough to support the weight of the hot tub and its contents.

Adjust the Hot Tub on the Patio

Once the laser level, prop leveling blocks, and other tools have been prepared, it’s time to adjust the hot tub on the concrete patio. It’s important to move it slowly and evenly so that it doesn’t become unbalanced. The blocks should be placed under the hot tub and adjusted so that it is level and evenly distributed. Care must be taken not to lift the hot tub too high or too low during placement, as this could damage the patio or the hot tub itself. Once the hot tub is in the desired position and approximate level, it’s time to secure it in place. Placement should be checked and adjusted as necessary until the hot tub is secure.

Check the Level of the Hot Tub

Once the hot tub is adjusted and leveled, it is important to check that it is level by using both a four-foot level and an allowance line. This will ensure that the weight is distributed evenly and that it is safely placed on the patio. If adjusting one side of the hot tub affects the other, then additional leveling blocks or blocks with a higher clearance may be needed. By confirming the level of the hot tub before securing it with additional blocks, it will be possible to provide a safe and even foundation for the hot tub.

Add Additional Leveling Blocks as Needed

Adding additional leveling blocks is important for ensuring that the hot tub is properly leveled on the patio. To ensure the leveling blocks are secure, drill a few holes in each block and use screws to secure them to the patio. Always use the manufacturer’s recommended screws for best results.

The added blocks should be placed under the hot tub, at least four inches away from the edge, to prevent shifting and ensure proper placement. If the blocks are not in the exact center of where the hot tub will be located, adjust the spacing accordingly. Repeat this step to add additional blocks as needed, adjusting until the hot tub is completely level. Use a level or allowance line as a reference while making adjustments.

Finally, use a hex wrench to secure the hot tub in place, tightening the bolts so the hot tub is secure and won’t move. Check all the levels once again to make sure the hot tub is level before using it. Adding additional blocks and securing the hot tub helps guarantee that it is level and properly installed on the concrete patio.

Secure the Hot Tub in Place

Once the hot tub is level and all of the blocks are in place, it’s then time to secure it in place. To do this, you’ll need to use screws and other fasteners. Here is a list of items needed to secure the hot tub:

  • Power Drill and Bits
  • Screws
  • Hex Wrench
  • Leveling Wedges

Using the power drill and drill bits, create holes in the blocks and the patio surface that are the same size as the screws. Insert the screws into the holes and use the hex wrench to tighten them. This will secure the blocks and the hot tub in place. Additionally, add leveling wedges to shift the blocks and hot tub to further ensure they are level and secure.

Now the hot tub should be successfully leveled on the concrete patio and secured in place. Check levels frequently to ensure that the hot tub remains steady and secure. With a bit of prep work and some tools, leveling a hot tub on a concrete patio can become a breeze!

Frequently Asked Questions

What happens if a hot tub is not level?

If a hot tub is not level, it can cause problems with the spa pumps, motor and plumbing. The water may not circulate properly and the hot tub may not heat correctly. In extreme cases, the shells and acrylic lining may be damaged due to the increased force created by the weight of the water when the hot tub is unleveled. Therefore, it is very important to make sure your hot tub is always level.

Does hot tub base need to be perfectly level?

No, in most cases a hot tub base does not need to be perfectly level. Depending on the type of hot tub, most hot tubs can tolerate up to 3-4 inches of slope. It is important to confirm the specifications for the particular hot tub you have to ensure the base is properly prepared for it.

Can you put a hot tub on a slight slope?

Yes, you can put a hot tub on a slight slope, provided there is adequate drainage and the slope does not exceed 2.5%. Slopes of this degree are usually safe for hot tubs as long as you level the area with sand or pavers, and also make sure it’s stable enough to support the weight of the tub and its contents. Additionally, it’s important to note that the structure should be built up so that the tub is lower than the area surrounding it. This helps with draining and safety.

Can you put a hot tub on concrete?

Yes, you can put a hot tub on concrete, but you will need to prepare the surface first. Make sure the concrete surface is smooth and level, and weatherproof the concrete with a waterproof sealant so that the tub does not leak. You may also need to reinforce the concrete pad with extra layers of cement under the hot tub to ensure it can support the weight of the tub and water.


In conclusion, leveling a hot tub on a concrete patio is a straightforward project that requires attention to detail. By using a laser level and prop leveling blocks, you can create an even and secure surface for the hot tub. The key to success is regularly checking the levels and adjusting the blocks and screws as necessary. With a bit of patience and a few tools, you’re ready to tackle the project and learn how to level a hot tub on a concrete patio.
