Choosing the perfect hot tub placement is a crucial decision. Your new hot tub adds that finishing look of luxury to your home, whether placed indoors or outdoors. Since preparing the chosen space for the hot tub costs money and time, you should devote some thought to the issue before making your final choice. After all, you don’t want to install a hot tub, look at it, and then decide you need to move the entire kit and kaboodle to a different location.
But how do you decide on the perfect a hot tub place? Most of the articles which provide guidance on this topic are not very helpful, if only because they are written in such technical language that you can barely understand the advice given. But we have reviewed and summarized the leading manufacturer guides, expert advice, and customer experience. From all these sources we’ve culled the most useful and clearest instructions for installation of a hot tub.
Most likely you already have a hot tub place to install. We will consider the full range of outdoor and indoor options for installation hot tub. Let’s anticipate how the hot tub might look in different places of settings.

The most popular hot tub placements are also the simplest: either in your backyard or anywhere close to your house. The advantages install a hot tub in your backyard:
You can choose almost any place (we will cover the details later), but the key is to have a firm foundation (max 10x10ft / 3x3m), that can bear the weight of your chosen model. A hot tub cannot just be dropped on your grass plot (or even pressed soil) without proper preparation. Given the weight and constant water use, it’s easy for your hot tub to shift, with the risk of injury or damage. Besides, the first step into your hot tub should start on a comfortable surface, since the whole purpose of a hot tub is relaxation.
These are the kinds of surfaces which help make your experience perfect.
This paving is perfect for hot tubs. The material is usually already at the required standard, so you need only to ensure that the surface is level and the paved area can accommodate the dimensions of the hot tub.
Placing hot tub close to the house means a shorter walk, shorter electrical cables (which helps prevent power overload) and your house itself provides cover from wind and sun.
Most houses have a deck around the entrance doors or along the wall. Consult with your contractor or any building specialist about how much weight your deck can handle. Even if a standard hot tub is too heavy, you still have the option of getting an inflatable 1- or 2-person model, whose weight most decks are built to take.
Alternatively, you can build a custom deck and create a great setting for your hot tub. We advise hiring a specialist for this project, though.
If none of the above options are suitable, you can prepare an appropriate hot tub placement from scratch.
Cheaper but longer option for hot tub placement
The most durable solution is a concrete slab, which you can pour at your chosen location. A smooth slab gives a finished look and a solid platform for your hot tub. The average cost is between $150 and $200.
Measure the dimensions that fit your hot tub. Remove the sod to a depth of three inches. Place 4-inch-tall limiter bars. Pour the concrete into the space in two to three layers, smooth with a long straight bar, and leave for at least 72 hours. Gravity aligns the slab.
Faster but more pricey hot tub placement
If you don’t want to do a lot of work, you can use Pre-fab Pads instead. It’s simple, but more expensive. You will need six pads for most models, which will cost between $450 to $500. Pads can be placed straight on your grass plot, but the surface MUST be level. It’s also best to use gravel for backing under the pads.

You don’t need one. Hot tubs are not subject to building regulations.
However, if you want to build a separate building for the hot tub, there are certain restrictions you must follow in order to avoid permit requirements:
1. Only single level building;
2. Not higher than three meters;
3. Structure must be closer to your house than to the road;
4. All additional buildings around the house should occupy less than 50% of the area compared to when the house was built
So you are almost entirely free to create a place to relax in the yard. However, if you want to build a gazebo or a fence, you will need a permit.
Some neighborhoods do have rules about building pools, but hot tubs are not usually included.
Whatever location you decide on, bear in mind that the hot tub has to be delivered on the place. The delivery truck can’t drop it off and then you see about moving it to the location. There are several possible hot tub delivery options: by trailer, flatbed truck, or by cart. And, depending on the accessibility of the location, you may also need a crane to put the hot tub in place.
Hot tubs are typically delivered on their sides resting on a wheeled base. For a standard delivery, you will need to have a clearance width of at least 42 inches and a clearance height of at least eight feet from the road to the place where the hot tub will be installed.
If your chosen location isn’t accessible for a standard cart or truck delivery, ask the seller about the possibility of using a crane. This is a special option, but some companies have it. This may be necessary if you want to put your hot tub on your balcony, roof or backyard.
Outdoor water connection is through a standard garden hose. This can be used for both filling and draining the hot tub.
It is very important to use a proper electrical connection for your hot tub. Never use extension cords – instead, connect the hot tub directly to an external power source. Read the hot tub guide on electrical requirements.
There are two main kinds of hot tub connections
This option is often called Plug and Play, because a hot tub can be just plugged into an outlet. This voltage is not too high and does not require additional outlets or safety features. However, the power must not be less than 15 amp GFCI.
240V models are more powerful and heat quickly, so most of them have to be wired directly to the power supply. You must have more than 15 amp GFCI (38-60, depending on a hot tub ). You will also have to connect an RCD (residual current device) six feet from the bath. For this type of work, you should have an electrician do the installation.
Except for inflatable models, hot tubs are built for winter weather. So don’t let that factor into your decision to put your hot tub indoors or outdoors. Every hot tub model has a “non-freeze” mode (or some other title with the same function) so the only real question is whether your hot tub capacity provides you with comfortable temperatures in any season.
Hard-wired 240V models maintain temperature efficiently in cold weather. If you live in a cold region like Saskatchewan with winter temperatures often falling below 10*F, and you still want to soak in your hot tub, you will need a powerful hot tub with 3kW-5kW heater, which are 240V. A good example of a winter-approved hot tub would be the AquaRest 300.
An excellent solution for relaxing is an inflatable hot tub. They are equivalent in most ways to a standard hot tub and have a number of advantages, such as:
An empty inflatable hot tub weighs about 65 to 100 pounds. That means you can carry the tub to any place you want by yourself. It’s good for use in cases of limited space, especially inside the house. When an inflatable hot tub is filled with water and has two persons inside, its typical weight is 2,500 lbs. Most floors can withstand this.
SaluSpa Miami, for example, can accommodate four people. This inflatable hot tub is big enough for a family with a couple of children, or very roomy for two adults. You can find out more about this and other inflatable models on the site
Inflatable hot tubs have specific advantages and disadvantages, but they almost always can give you the option to place a hot tub where standard models can’t be installed,
You can inflate it, drain it, and deflate it pretty quickly. It’s especially handy if you want to soak a couple of times a month when you throw parties.
This is a trickier issue because of the additional issues you need to consider. Regularly using a hot tub in a room that hasn’t been properly prepared can lead to long-term damage to your home, ruin your vacation, and even affect your health.
If you live in an apartment, don’t put in a hot tub without the permission of the landlord.
U.S. residential building codes specify a floor live load of 40 Lb/ft². For example we take SaluSpa Hawaii Hot Tub as the most lightweight (1,938 Lb when 80% filled) among the inflatable spas with bigger area (34.88 ft²). 2000 Lb / 34.88 ft² = 57.3 Lb/ft². It’s close to normal but more, than permitted,so it cannot be used in its entirety. Even 100 gallons in a hot tub, because of its small area (approximately 10 ft²) will be 83,45 Lb/ft².
In that situation, one solution may be to not completely fill the hot tub (this will not violate the permit). You may be able to find a compromise with the landlord.
Once your heart is set on it, there is nothing impossible, even something as simple as installing a hot tub. Let’s take a closer look at some additional options.
This is a popular place and may be a good option as it is separated from the main living area of the house. The basement floor can support a hot tub of any weight. (After all, it’s supporting the entire house.)
However, it’s very important to remember that a hot tub is a massive source of moisture. The heat from the bath reacts with the colder room temperature, and condensate forms on the walls, ceilings and windows. Together with steam, this can lead to mold and rot. Quality ventilation is therefore essential for indoor hot tub installation (believe me, you’ll regret it if you don’t have it). As a last resort, you can instead use an in-room exhaust fan.
To ensure that moisture does not appear, we also recommend using a fan heater to equalize the room temperature in order to prevent condensation. It’s also advisable to add a dehumidifier.
If you have a basement below your ground floor, call your contractor or consult with your Homeowners Association about how much weight your floor can handle. Bear in mind that wooden floors are a bad choice for hot tubs. Choose rooms where you have a concrete floor or a tiled surface.
The best place in your ground floor is the bathroom. Usually, a bathroom already has ventilation. Most other rooms in the house will be damaged by moisture. But if you can’t put the hot tub in the bathroom, a dehumidifier can help (check out our advice for the basement).
If you have enough money, you can create a custom room for all your hot tub needs. Here’s what you can do to make a perfect hot tub room:
Summary of what you’ll need to install a hot tub indoors:
Choosing the right place for your hot tub is a very important decision, but there is nothing complicated about it. You just need to consider the specific requirements for each option.
For outdoor locations. you can install any hot tub that you choose and you don’t need any special permits to put the hot tub outdoors or to build cover constructions. It’s not a problem to use hot tubs in winter (except inflatables, which won’t work in a cold winter).
When placing a hot tub indoor, it is important to evaluate the structural capacities of your floor as well as the ventilation system
If, for any reason, the size and weight of the hot tub are unsuitable, consider buying an inflatable hot tub.
It depends on your conditions and resources. The best possible variants are:
– A wide stone or concrete paving around the house
– Deck around the backdoor
– Any ground space (with some preparations – you can find them in the article)
Air jets work using a blower (which inflates the hot tub) that in turn pumps air through a series of tiny holes. When there is enough air to pass through the holes in the hot tub, a force is created which results in a gentle, tickling, and a pleasant massage effect. They are comparatively cheaper than hydro jets. You don’t need a building permit. Hot tubs are not subject to building regulations. However, if you want to build a separate building for the hot tub, there are some restrictions that you must be aware of (Learn more in our article).
It is important to have a firm foundation (max 10x10ft / 3x3m) that can bear the weight of your chosen model. You cannot just place your hot tub anywhere, like on the grass (or pressed soil). Given the weight and constant water use, it’s easy for your hot tub to move, increasing the risk of damage and injury. You have to prepare a proper place before you place your tub somewhere.
To use the jacuzzi outdoors in the winter, make sure that it has a “non-freeze” mode. Turn it on at the first cold snap. Inflatable hot tubs can be used outdoors provided the temperature is above 40°F.
You need to prepare a suitable surface for the hot tub. There are 2 ways that you can do this: a concrete slab (cheaper but long-lasting option) and Pre-fab Pads (faster but more pricey).
Only in some cases. According to U.S. residential building codes, permitted floor load on the balcony can be from 30 Lb/ft² or more. Before installation, ask technical specialists what kind of load the floors on your balcony can withstand, or you may be in for another surprise.
