The short answer
Before a hot tub arrives, pick a spot close to the back door with a clear delivery path, build a flat, level, well drained base that can carry the full weight of the filled tub (a concrete pad, pavers on a compacted base or a framed gravel pad), and have a licensed electrician run the circuit it needs. Most full size hot tubs need a dedicated 240 volt GFCI protected circuit, and electrical code calls for a disconnect within sight of the tub and at least 5 feet away from it.
Pick the spot
Close to the back door is used more in a Michigan winter than a spot across the yard. Check the path for the delivery: gates, steps and tight corners all matter, so measure the tub's width on its side against the path.
Build a base that will not move
A filled hot tub is heavy, often several thousand pounds with water and people. The base has to be flat, level and well drained. Common choices are a poured concrete pad, pavers on a compacted gravel base, or a framed and leveled gravel pad. Follow your hot tub maker's base requirements, because they can affect the warranty.
Plan the power early
Most full size hot tubs need a dedicated 240 volt circuit with GFCI protection, installed by a licensed electrician, and many townships require a permit. Code calls for an emergency disconnect within sight of the tub and at least 5 feet away. Smaller plug in models use a standard outlet but heat more slowly.
Privacy and shade
A privacy fence, lattice or plantings make the space feel like a retreat. A shade sail or pergola keeps the sun off during summer and leaves off the tub cover.
Make it easy to get in and out
A patio or pavers around the tub keep grass and dirt out of the water. Sturdy steps, from the door and up to the tub, matter more than people expect, especially on icy nights.
Drainage
Water will splash out and the tub will get drained a few times a year. Slope the area away from the house and know where the water will go.

Spa installation and backyard patios in Southwest MichiganCommon questions
Can a hot tub go on gravel?+
Yes, if the gravel is compacted, level and contained, such as in a framed timber border. Check your hot tub maker's base requirements.
Can a hot tub sit on a deck?+
Only if the deck is designed for the weight. A filled tub is far heavier than a normal deck load, so have the framing checked or built for it.
How far does the electrical disconnect need to be from a hot tub?+
Electrical code calls for it to be within sight of the tub and at least 5 feet away. A licensed electrician will place it correctly.
