Can You Add a Hot Tub to Your Deck?

If it’s always been a dream of yours to install a luxurious hot tub to your deck, why put off that dream any longer? But you may wonder: is it even possible to put a hot tub on a deck? Well we are here to tell you that yes, it’s possible! However, first you will have to determine if your existing deck can handle the weight of a hot tub.  

You should always consult with a Boston deck contractor first before beginning such a project.

Call a Pro

It’s not a good idea to DIY your hot tub addition project. This type of project takes careful planning, attention to detail, and the help of qualified contractors like AD. A weak deck could actually collapse under the weight of a 1,000+ pound hot tub, so ask for a consult first. If your deck can’t sustain the weight of a hot tub as is, your contractor can build a new deck for you or add supports to the one you have.

Types of Hot Tubs: Decks 

You have two options for hot tubs and decks: one that will sit atop your deck or one that is set into your deck. If you have a beautiful view that you don’t want to obstruct, or you don’t want to climb into and out of an above-ground tub, you’re better off going with an in-ground tub.

That being said, the above-ground hot tub makes for an easier addition to an existing deck, but always verify your deck’s weight capacity first. 

Installation Requirements

Hot tubs need a solid, flat surface for installation. A concrete slab is a good example, as it’s flat and sturdy enough to provide a supporting base and it should be installed in accordance with your concrete deck footings. A four-inch slab is enough in most cases, unless you plan on installing a very large or heavy hot tub.

Calculate Deck Load Capacity 

To make sure your deck is structurally sound, you’ll have to make some calculations. Here are the general calculations used to determine deck support:

  • Weight of Empty Hot Tub
  • 1 Gallon of Water = 8.34 lbs
  • Average Weight of Human = 185 lbs
  • Square Footage of Hot Tub

Most decks can withstand 100 lbs of weight per square foot. Don’t guess, though. Always consult with a professional.

Selecting the Right Hot Tub

A hot tub is a big investment. You’ll likely be spending several thousand dollars or more, depending on the model, so don’t rush your decisions. You should choose the hot tub you want prior to making any structural changes to your deck or building a new one. Here are some tips for choosing the ideal hot tub:

  • Research manufacturers online.
  • Read reviews from other hot tub owners.
  • Test out hot tubs you are considering. Make sure you can sit in them comfortably.
  • Determine the cost of regular maintenance.
  • Take warranty coverage into consideration.
  • Ask about transportation and installation costs with the manufacturer.
