How to Set up a Hot Tub on Gravel

When setting up your hot tub, you'll need a solid and strong foundation to place it on. Gravel bases work well for hot tub setup -- they're durable, drain well and require little maintenance. Prior to beginning your hot tub installation, make sure that you have a proper electrical supply installed by a qualified electrician.

A hot tub can be a welcome addition to a home.
  1. Rake the gravel pad where you'll be installing the hot tub to ensure that the gravel is level and free of any debris.

  2. Place the hot tub in the desired location and make the necessary electrical connections. You may need to hire a qualified electrician to do this.

  3. Clean the hot tub of any debris or dirt with water and a mild cleaning solution. Check the manufacturer's recommendations for specific cleaning agents. Tighten all water pump fittings by hand and tighten the drain valve.

  4. Fill the hot tub from your hose to a level 2 inches above the filter intakes. Turn on the hot tub and then activate any jet nozzles on the tub. After they've run, shut off all the jets and set the tub temperature. Let the tub heat to the desired temperature. This may take up to 24 hours.
