Things to Know Before

Putting a Hot Tub on Your Deck

A large spa or hot tub can weigh more than 3 tons when it’s filled with water, which is heavier than most cars and trucks.

2. What size of hot tub is best for my deck?

Create a cardboard representation to test out where you might place the tub, or use painter’s tape to mark out a space on the deck.

It’s crucial to have a professional inspect the condition of the decking, joists, hangers, bolts, and screws.

A hot tub needs an electrical outlet to power its heating element and pump.

5. How much will it cost?

When most people begin researching the cost of putting a hot tub on their deck, they typically only look at the cost of the hot tub or spa itself.

Make sure there is enough room to allow access to your deck to perform the installation.

7. How do you prep  the deck surface?

It may be a good time to refinish the wood with a fresh coat of deck stain to protect it from water that splashes out of the spa.

With this type of installation, the hot tub surface sits nearly flush to the deck, giving it an in-ground look.
