Can You Sink a Hot Tub into the Ground?

Deciding on where to place your hot tub and how to integrate it into the surrounding area will play a long lasting role in the look and feel of your new installation. One installation style that’s become more popular of late is sinking the hot tub to reduce the prominence of its profile. So, how can you sink a hot tub into the ground? The fact is that there’s a lot more involved than simply digging a hole in which to place your hot tub. To help ensure you do this job properly and prevent the need for future excavations, we’ve put together a list of considerations for sinking your hot tub into the ground.


The first thing you’ll need to do to prepare for sinking your hot tub into the ground is to compare the hot tub’s measurements with the area you’re working with. Not only will the hole need to fit the hot tub, but you’ll need extra space all around to allow for future service, running the electrical supply and to permit problem-free drainage. Give yourself at least a couple of feet on each side of the hot tub to allow access to its components.

Power and Drainage

You’ll need to account for the locations of your hot tub’s power and drain points when working on your excavation. Having enough room for the electrical cable to run from the hot tub to its connection point is something that’s not always properly thought out when digging. Same with the drain on your hot tub. Knowing where it’s located and coordinating that with your excavation will prevent having to go back and do it again before the hot tub is lowered into place. Beyond draining the hot tub, itself, the site must also have proper drainage for rain and other precipitation. The accumulation of rainwater or meltwater can cause significant problems.

Access for Service and Maintenance

As mentioned, you’ll need to leave some space around all sides of the hot tub for the possibility of future service and maintenance. You’ll need enough space to be able to remove the cabinet panels and allow a person to get down in there and access the hot tub’s inner workings. Similarly, you can’t completely seal off the lower sections of the hot tub cabinet. The last thing you want to do if you run into problems is to have to pull the entire hot tub out of the ground.

Hot Tub Cover Considerations

A hot tub cover is one of the most important accessories associated with a hot tub. Not only does it provide safety by keeping our children and animals, but it will also play a major role in retaining heat and preventing the accumulation of airborne contaminants. Hot tub covers usually latch onto the edges of the hot tub, so you want to make sure those latches are still accessible to allow the cover to be properly secured. Also, if you’re planning on using a cover lifter, you want to make sure there’s enough space for it to function properly.

Stereo Speakers

Some models of hot tubs feature speakers on the outer edges of the hot tub cabinet. This might not be completely compatible with a sunken hot tub. If you choose a hot tub with built in speakers, you’ll need to consider their positioning when planning your excavation. Speakers located several feet below ground may not be entirely functional.

Lifting Straps

Lifting straps will help you lower the hot tub into position. It’s probably a good idea to leave them there in case there’s an eventual need to lift the hot tub out again. Speak to your hot tub dealer about the use of lifting straps and the appropriate type for your model.
