Before we get started, let’s review why you should give your hot tub a base to begin with.
First and foremost, there’s your hot tub’s weight: Even if you purchase a relatively small hot tub, it will still weigh thousands of pounds.
After all, just one gallon of water weighs 8.34 pounds. In a standard 400-gallon hot tub, that comes out to 3,336 pounds of water weight, not including the hot tub itself.
Needless to say, a hot tub that weighs thousands of pounds will not sit evenly on a grass or dirt surface. Rather, it will sink significantly, ruining your yard in the process.
You also need to consider the damage your hot tub will incur if placed on a grass or dirt surface.
Even in dry climates, the lower layers of soil are moist, and over time that moisture will wreak havoc on your hot tub’s structural integrity.
Remember, even though hot tubs are designed to hold water, their exterior surfaces are not designed to withstand prolonged water exposure.
Now that you know why it’s so important to give your hot tub a base, let’s look at four of the best base and foundation ideas.
