Will Joist Hangers Support A Hot Tub?

Joint hangers and hot tubs are almost the same things: floating around in the water at a higher temperature than you would find indoors.

Joint hangers and hot tubs offer an undeniable sense of relaxation, a rare meeting spot for young people in the summer and older people throughout the year.

No. Joist hangers can’t support a hot tub since they are “graded” beams. They’re not strong enough to support a load like a hot tub, especially when you factor in the amount of moisture that a hot tub creates. A joist hanger would allow the tub’s weight to align with the structure.

Your hot tub’s support must first have a support that can hold up its weight like an existing beam or joist.

A gusset plate, which is the most common type of support, has holes drilled into it in different spots and which you can join with screws to create firm and secure supports.

Another type of support is a ledger board, which has been the most popular. A ledger board is a wide piece of wood that can join joist hangers.

You would need an extra joist hanger at each end to join your hot tub to the ledger board.

One other type of support is usually for wall units and the like, but you can also add it underneath your hot tub.

You can use large bags of rocks and sand, which will provide enough support for the weight of your hot tub.

Many people think it’s okay to use joist hangers as they don’t realize they are not strong enough.

The most popular system for supporting a hot tub is the ledger board. Ledger boards often retain walls, but Quality Hot Tub is the only place I know of that uses it for hot tubs.

This system works so well because you can use larger pieces of wood to support the weight of your hot tub, which results in much more robust support than what you would get with joist hangers.

What Size Joist Does One Need To Support A Hot Tub?

You need a 2*4 size joist to support a hot tub. After you buy the joists, you’ll need to install them on the floor of your house.

You’ll also need to construct a support beam between two of them to prevent an unstable feeling.

You’ll want to check the installation instructions for your specific hot tub before installing either of these parts.

Once installed, I recommend keeping weight off of it for at least three days, as it will take some time for everything to settle and be comfortable.

To help put everything in place, I recommend installing them on a level floor before installing the support beam.

You can start with a smaller joist and add extra ones as needed later.

I suggest selecting an inexpensive joist that will allow you to install more in the future if that becomes necessary. They are usually more affordable and on sale when it’s time to replace them.

Usually, the maximum weight load is 250 pounds per joist. This is enough to support a big hot tub with lots of weight, but it may not be enough to support a small one.

You’ll probably want to check the manufacturer’s instructions on how heavy the tub is and how much weight it can sustain before buying.

You don’t need a new joist for every hot tub you install. You can expect to have about 4-6 joists in each bathroom and possibly even more if multiple bathrooms are close together.

The support beam you install in the middle of the joists will get attached to both ends, so it doesn’t move.

You can also install it through a joist, but you’ll need to put a structural I-beam system for extra support and stability.

How Do I Build A Deck Strong Enough To Hold A Hot Tub?

You can build a deck strong enough to hold a hot tub by following a few easy steps.

Step one: Plan where and how you want the hot tub. Consider the deck’s size if you want an overhead shelf for a railing at all four sides of the hot tub and how many stairs the deck will need.

Step two: Choose materials for your deck. You can use pressure-treated wood or cedar lumber and polyurethane sealant or paint to protect it from water damage.

Look at your deck plans and determine how many boards you need to build the deck.

Ensure the wood is pressure treated by using a sealant or painting it before construction.

Step three: Mark the area of your deck on the ground using garden hose spray-painted white and line it up with a wooden fence post or some other heavy object to make sure it is square and straight.

Next, dig holes for your posts. If you are using pre-made deck posts, follow the instructions for placement on the box.

Ensure your holes are deep enough to bury the post at least 4 feet. Check with your local building codes to be sure you are digging your holes deep enough.

Step four: Place the posts into their holes; tamp the surrounding dirt, and add a little sand on top so that the post does not float in your concrete.

Step five: Mix concrete and pour it around each of the posts, ensuring to get it all full, deep, and well mixed.

Step six: Wait at least 24 hours for the concrete to set.

Step seven: Drive screws into each deck board about 2 feet from the top or bottom of each post.

Use three or four screws on each board, and make sure you have every board evenly centered between two posts.

Step eight: Set your deck on top of the posts, making sure it’s level and square with a spirit level.

Step nine: Take a level and nail 3″ galvanized nails into the edge of the wood along the entire outside of each board. Do this at every post as well.

Step ten: Take your boards, paint them, or seal them with a sealant to protect them from water damage.

Step eleven: Attach your shelf pieces on your hot tub’s left and right side using 3″ galvanized nails, varying their length from 2″ to 4″.

Step twelve: Add your railing if you want one; you can attach it to the corners of your hot tub with 3″ nails or attach it to the side with brackets.

Next, build a fire pit or add patio furniture to complete your backyard oasis.

Can My Floor Support A Hot Tub?

Yes. For your floor to support a hot tub, you must adequately reinforce it to handle the weight.

As for heat, the floor has a specific heat capacity and can dissipate a certain amount of heat before it becomes too much and causes problems with either the hot tub or your house.

The floor also needs sufficient insulation from beneath to keep the temperature from reaching into your house and causing issues.

The best way to handle this is by installing an outdoor concrete slab that sits on top of insulation boards. This keeps the floor from heat effects.

The concrete should be two inches thick and have proper reinforcement to handle the weight.

This slab is usually on top of a layer of insulation boards. The insulation boards contain closed-cell polyurethane that extends 2-3 inches above the floor surface for extra heat protection.

These boards are resistant to water and insulate well, keeping heat out of your floors below. One can even use them underneath a stone or wood deck as an insulator.

Can You Put A Hot Tub On Pavers?

Yes. You can put a hot tub on pavers. This can prove to be quite a challenge, but it’s one that you should take on if you have an acre of free space.

All you need for the hot tub is a waterproof liner, which you can get from companies like?. The biggest issue with the installation is determining where to place the pump.

You’ll want to place it in an area that doesn’t fill with water when a hose gets attached or near your electrical meter.

You can also mount the pump at an angle to ensure that it doesn’t block water flow.

The materials for a hot tub on pavers are about the same price as a hot tub in your backyard.

The major difference is that a hot tub on pavers usually takes up more space than a traditional one.

The liner will take up room, and the pumps you need will take up more space, but with all the benefits you get from having your Spa, it’s well worth it.

You must insulate your hot tub as expected, and it’s even more critical when you place the hot tub on pavers.

Because of its installation method, you are taking away moisture from the ground, and if there isn’t a good way to return it, the ground beneath your home will dry up.

The hot water in the tub probably won’t be able to heat because there isn’t enough moisture or heat in the ground.

It will be a colossal waste of money, and the pavers probably won’t even last as long.

Can A Trex Deck Support A Hot Tub?

Yes. A Trex deck can support a hot tub. If you consider adding a hot tub to your outdoor living space and want the maximum amount of protection for your investment, a Trex deck could be an attractive option.

Trex decks are usually laid over pressure-treated wood joists with fiberglass insulation that can protect people from falling through the deck if appropriately built.

If you work with a Trex authorized installer, they can help you determine the best foundation for your hot tub.

They will be able to talk to you about all your options and help pick out suitable materials and accessories to ensure safety and functionality.

If the budget is a concern, keep in mind that there are ways to work around costs.

The thicker the deck board, the better it can support weight–but thicker boards also cost more.

If you use your hot tub occasionally, you might use a less expensive deck board and add an optional hot tub pad to the bottom.

As for hot tubs, there is no single, straightforward answer for ensuring that your deck can handle the weight of a hot tub.

It is best to speak with a contractor who can help you make the right decision for your situation with any home improvement project.

Does A Hot Tub Have To Be Perfectly Level?

Yes. A hot tub or jacuzzi needs to be perfectly level for its jets to function well and for the water in the tub to remain at a constant level.

A common misconception is all that’s required for a hot tub’s jets to work is some space between the bottom of the Spa and the ground.

However, this space must allow air to flow around under and over the tub to circulate properly, which means at least 3-4 inches of clearance space beneath your Spa.

Also, a hot tub must be level to cushion the water well. Each square inch of foam significantly affects the overall comfort level of your spa and the way it feels on your back or bottom.

Suppose a fine layer of water is evenly distributed throughout all parts of the water-filled sphere in your hot tub when you move around in the tub.

In that case, you feel like you are sitting on that same layer of pure water instead of on a cushion of air or water sparsely distributed throughout your Spa.

If the water layer gets unevenly distributed, you may feel pressure points against your skin, and your back or buttocks may not enjoy a comfortable feeling.

Do Hot Tubs Have Leveling Feet?

Yes. Hot tubs boast leveling feet placed on level ground, usually around the outside of the tub.

These feet ensure that a hot tub is stable and people can’t rock it, even when they are sitting or standing right next to it.

That’s because hot tubs can weigh as much as 3 tons, and sitting or standing too close — or even jumping in — could put undue pressure on the sides of the unit, causing damage over time.

Hot Tub Leveling Feet: Types and Technologies

The most common type of hot tub leveling foot is the T-shaped design.

One leg gets attached to one side of the tub, and another leg gets attached to a central support bar, usually near where you will place the tub in your home.

Attaching the legs to the support bar means easily setting up the hot tub at the desired level.

Some T-shaped feet get permanently attached to the tub, while others you can remove and place in different locations during setup or taken off when not in use.

The latter type has become very popular as it eliminates storage concerns.

Another type of foot is a j-shaped one. This design is not so common but is gaining popularity as manufacturers release new models, including this foot as standard equipment.

J-shaped feet are usually to the bottom of the tub, underneath where it would usually rest on a deck.

This means that you can place the hot tub closer to the ground, and you don’t have to elevate it as much to reach an appropriate height.

The third type of foot is a self-leveling one. One raises them by hand and sets them at the desired elevation level before locking them. You mostly find them on Spa models with built-in pumps.

These are also popular in smaller Spas where the weight of the hot tub doesn’t need a lot of extra height.

Lastly, some manufacturers don’t use afoot and instead raise the side of the tub through a hydraulic pump or other devices.

You don’t have to manually operate the pump since one can permanently install it and connect it to your hot tub.

Can You Use Porcelain Tile As Pool Coping?

Yes. You can use porcelain tile as pool coping, and it’s an excellent material for this purpose.

You can install it for swimming pools in both above-ground and in-ground pools. Sometimes, tile can also provide a line at the bottom of the pool that is safe for entry.

This type of tile is usually cut to size and requires no grouting or tiling adhesive. This type of tile is often used in hard water areas, where tile can easily fall off of pool walls.

How to install tile for swimming pools

Decide what type of tiles you would like to use for your pool coping and prepare your pool base to remove any dirt and debris which could prevent adhesion.

Some swimming pools have the tiles set onto a layer of mortar or epoxy, while others will have only the tiles themselves holding them in place.

If your pool has a mortar base, you may need to drill holes in the tile to allow water to drain.

You should set the tiles onto mortar or epoxy by placing them where they need to go and tapping them gently (with a rubber mallet if necessary).

Ensure that they are flush with the tops of the pool wall and that there are no gaps between them.

Use a tile saw or grinder if you have to make any cuts on the tiles, but be careful. They may crack relatively easily.

If you plan to use the tile for both above-ground and in-ground pools, you must amend the tiles every few years to ensure that they are as durable as possible.

You can achieve this by using a grout sealer or mud. This will extend the life of the tiles by preventing water penetration.


Hot tubs and pools are both excellent sources of relaxation and recreation, so they are popular choices for many people.

The benefits of owning a hot tub are endless, and it’s not uncommon to find people who wind up owning two or more spas to enjoy them during the weekends.


Hi! I' am Tom. I was a manager in one of the biggest stores for over 10 Years, am also an SEO by night. I don't like to call myself a blogger; they are very analytical, do email marketing, and know all SEO stuff. I faced many questions from customers about different products, and there was hardly any help on the internet. After learning all the things about these products as a manager the hard way, I decided to start a blog and help other people.
