Sunken hot tub decks are a great way to bring your hot tub into your backyard design. They can add value and style to the space, and they’re an excellent place to relax after a long day at work.

How to make a hot tub deck

  • Dig holes for the posts.
  • Set your posts in place and check for level, then attach them with concrete anchors and bolts or lag screws (depending on your decking material). If you’re using treated lumber, set it in concrete as well—this will prevent rot from setting in over time.
  • Attach beams to the sides of each post to support your joists and create a solid base for attaching deck boards later on down the line. You can use either galvanized carriage bolts or lag screws here again depending on what type of wood you’re using… those are usually what I use anyways because they hold better than nails do but it really doesn’t matter too much either way since everything will be covered up by decking boards anyway so just go with whatever works best for you!
  • Install joists on top of beams, spaced evenly apart so that they’re a comfortable enough distance between them so that people won’t bump their heads when walking around underneath them… also make sure there’s plenty of room left over between each one so that people aren’t stepping right onto another person’s toes when walking around underneath them which could cause bruises if someone wasn’t careful enough 🙂 Again though this doesn’t matter too much since everyone else who comes over won’t see these anyway because we’ll cover everything up with fancy-looking floorboards afterward!

Building your own hot tub deck is fairly simple, but it does require some planning.

Building your own hot tub deck is fairly simple, but it does require some planning. You need to gather the right tools and materials, as well as have a plan for the project. If you are unsure of what you need, hiring a professional may be in your best interest.

Here’s what you need to know about building your own sunken hot tub deck:

Before you begin, take some time to plan your design. This is the most important step in creating a hot tub deck because it will help you determine how much space you need and what materials and tools are required to complete the project. You must also decide whether or not you want a built-in bench around your hot tub, as well as any plantings or trees that might enhance the look of your sunken hot tub deck.

  • Determine how much space you have available within which to build a deck around your existing hot tub. You should leave at least three feet between the edge of the decking material and any walls surrounding your home so that no one gets injured when sitting on it or walking past it at night.
  • Create an outline for where all elements will go; this includes plantings, benches (if desired), seating areas for guests during parties/family gatherings etcetera…

Deciding on a location for your hot tub deck

Once you’ve decided on a location, it’s time to start building your deck. The first thing you should do is make sure the ground is level and flat so that the hot tub will be stable. Your hot tub should also be at least 6 feet away from any trees or structures to avoid damage or injury. You must also keep it at least 10 feet away from your house or pool in order to prevent heat loss from escaping through evaporation into other areas of your yard. Finally, while it may seem like common sense, it’s important not to place your newly constructed deck too close to another area that will be subjected to high levels of moisture such as patios or walkways where water might collect after heavy rains and cause damage over time if left untreated.

The most important part of building a hot tub deck is deciding where to put it.

The most important part of building a hot tub deck is deciding where to put it. You need to have space for the hot tub and walkways around it, as well as room for any plantings you want to include in your design. If you’re lucky enough to have a large yard, then there will be plenty of room for your deck’s foundation without encroaching on other areas of the property. However, if you live in an urban apartment or condo building with limited outdoor space, this may mean that putting in a new deck just isn’t feasible right now—and that’s okay! Hot tubs can still be a great addition even if they’re not placed outside; many people find success placing them indoors on their living room floors or near their fireplaces (this is especially nice if they spend winter months away from home).

The next step after deciding where exactly where on Earth–or Mars–your hot tub should go would be measuring out its dimensions! You’ll want enough space between each side that everyone can comfortably fit inside once everyone has gotten settled into their seats without bumping elbows all night long…or else it won’t feel like much fun at all!

Determine how much space you want around the hot tub and make sure you have room for walkways and any plantings you want to include in your design.

How much space do you want around your hot tub?

The majority of homeowners opt for an 8-foot wall or higher. It’s important to leave enough room for a comfortable walkway around the hot tub and any plantings you might want to include in your design. If you’re planning on adding a deck or patio, consider how much space it will take up as well.

Plan for the utilities

  • Plan for the utilities.
  • You need to know what you need before you start building.
  • This includes water, electricity, and gas.
  • Depending on the location of your deck and how it will be used, you may want to hire an electrician or plumber to do this part of the job.

Next, think about how you’re going to hook up the water, electricity, and gas.

Next, think about how you’re going to hook up the water, electricity, and gas. Hot tub decks are powered by 110-volt GFCI circuits that can be wired into an existing home’s electrical system or installed as a standalone unit. Once the power is connected to your deck’s circuit box or breaker box, you’ll need to run wires from there to each component on the deck like lights and jets—and also down into your yard where they’re connected to underground piping if you’re installing a self-contained spa (this means less maintenance). You may also have to hire a professional electrician for this part because wiring safety codes vary from one place to another—you’ll want someone who knows what local laws require before he or she starts working on your project!

The next step is hooking up water lines from inside your house through the hot tub deck walls down into its floor basin so that it can fill with warm tap water when needed (this will keep it from being exposed directly underneath ice during winter). It’s best if these pipes are located towards one end of your new deck so that they’re easier for people using them later on (you don’t want them tripping over them while walking around!).

Lastly: gas connections!

Consider hiring a professional electrician or plumber for this part of the project.

If you’re not comfortable with wiring or plumbing, it’s best to hire a professional for this part of the project. The same goes for electrical work if you don’t have access to an electrician who can help.

Professional plumbers and electricians will have the tools and knowledge necessary to do this type of work safely. They also have liability insurance in case something goes wrong while they’re working on your home that could cause damage or injury.

The supplies for building a hot tub deck

The supplies for building a hot tub deck include the following:

  • Post hole diggers and large shovels
  • Boards make forms that will hold the concrete in place while it cures and hardens. You’ll need enough of these boards to form a square around the perimeter of your hot tub, including an opening for access from outside your home. To calculate how many boards you need, measure the length and width of your hot tub and multiply them together. That will give you an approximate area for how much product is needed for each board; add about 20% extra so you can trim off any excess after laying down the first row or two but before pouring in any concrete – if there are any jagged edges or splinters left behind during this process then they will show through once poured into place!
  • Miter saws or circular saws (with appropriate blades)
  • Drills

You’ll also need some post-hole diggers and/or large shovels for digging out space for the frame and posts.

If you are using a miter saw, make sure it’s set up properly.

You may also want some boards to make forms to hold the concrete in place during pouring, especially when dealing with odd shapes or corners.

If you prefer, you can also buy forms (also known as molds) from a hardware store or online retailer. They’re often made from PVC pipe, which is lighter and easier to handle than wood. If you want to make your own, the process is simple: First, measure the space you need to fill with concrete and then sketch out the shape of your form on paper so you know how much material and how many pieces are needed. Once that’s done, cut pieces of 2x4s or similar lumber into appropriate sizes for each side of the form; then drill holes in all four sides so that they’ll be easier to hold together when pouring concrete over them. You’ll also need clamps (or rope) to hold everything tightly together once it’s in place—and don’t forget gloves!

Once everything is ready, start by laying down newspapers around where you’ll be pouring concrete. Next, pour dry cement into a wheelbarrow until it reaches one-third full; then start filling up one side at a time using shovels until all four sides have been completed (try not to fill too much at once). If necessary use something flat like plywood between each layer so they will stay straight while drying overnight before removing them completely later on down the road – this helps avoid warping due

If you’re not choosing pre-made spindles or railings, you’ll also need tools such as miter saws and drills to put together these pieces.

You will also need to purchase some tools to help you build your deck. These include a miter saw and drill, as well as a hammer, nails, a level, and a tape measure. A circular saw can also be useful if you are cutting lumber by hand.
