Tips for Indoor Hot Tub Installations!

An outdoor hot tub is not ideal for everyone, with some preferring the added convenience, comfort, and privacy of an indoor hot tub.

An indoor hot tub can be a part of a new home build or a renovation. Can you picture it? An updated master suite with a cozy two-person hot tub. Or, maybe it’s adding that three-season room with a four-person hot tub the whole family can enjoy.

Installing an indoor hot tub, though, has its own considerations.

Planning for an Indoor Hot Tub

Can you put a hot tub inside? Absolutely! But before you schedule your delivery, here are eight factors to take into account.

Hot Tub Size

We offer a variety of hot tub sizes so that you can find the spa that fits your space and needs. While an eight-person hot tub is great for entertaining, it might not be the best choice for indoors. If you want to put your hot tub inside, consider a two- to three-person spa. Or consider, a hot tub with a lower profile that will be easier to get through a doorway.

Filtration System

Among the “cons” of putting a hot tub inside is that some complain of a chemical smell. Indeed, chemicals are required to keep your spa water balanced. But a hot tub with a quality filtration system can help you avoid a strong aroma. Our hot tubs feature an Ozone Cleaning system. Plan for water access when choosing to put a tub inside.

Water Access

Just as you would an outdoor hot tub, you need to be able to fill your indoor hot tub. A hose is the most efficient way of filling a hot tub, and it will need to be able to reach your spa.


Splashing on the floor or ground is inevitable when you own a hot tub. The water moves as you get in and out of the spa, as well as shift between the seats. Even a jet on full power can cause some spray. But you don’t want water to damage the flooring of your indoor space. 

When you install a hot tub inside, be sure to think about flooring material and drainage. If your indoor hot tub is part of a renovation or new build, have the contractors install a floor drain. It will protect the flooring, as well as make it easier to enjoy your spa. 

It’s also important to plan for routine water care. We recommend that your hot tub be drained every 3 - 6 months. When it comes time to empty your hot tub, where will the water go? You can attach a garden hose to the drain or use a sump pump to help remove the water.

Water-resistant flooring is a must if you have an indoor hot tub. If you want to put a spa inside, also consider drainage.

Power Access

To connect your hot tub to power, you can either plug it into a wall outlet or wire it directly to the connection through your home’s central circuit breaker box. This will vary on the specific hot tub you are purchasing. (Please ensure you know this prior to any work getting carried out.) If you don’t have a proper wall outlet, you’ll need to install one. To prevent moisture-related short circuits, you’ll also need to install a ground fault circuit interrupter (GFCI) between your hot tub and power source as well. A licensed electrician should perform this work.


Just like an outdoor hot tub, you need to have a flat, level surface that can support the weight of the hot tub. Even if you think the floor is supported, it’s a good idea to contact an experienced contractor to evaluate your space. Windows can bring in natural light but also offer ventilation for an indoor hot tub.


The higher temperature of a hot tub, along with the water in the spa, can cause the indoor space to be humid. The moisture in the air can cause damage to paint, drywall, and your home decor. An efficient ventilation system can help you avoid any dampness or odor in the space.

Installation Route

One of the biggest challenges of an indoor hot tub is getting it indoors. Before buying a hot tub to put inside, review its specifications and talk with a qualified salesperson about how it will be delivered. It’s always a good idea to measure any doorways, hallways, or spaces that will be on the delivery route. An indoor hot tub offers additional privacy and convenience.

Benefits of an Indoor Hot Tub


A homeowner can create a private outdoor oasis with thoughtful landscaping. But unless you live on a sprawling property, it can be hard to find a true sense of privacy. An indoor hot tub can help you avoid catching your neighbor’s eye or hearing the neighborhood kids play. 


An outdoor hot tub can be installed just steps from your backdoor. But you can enjoy soaking in an indoor hot tub without having to put on a robe or slippers. 

Weather Protection 

Close that weather app. With an indoor hot tub, you don’t need to worry about whether it’s going to rain or snow. You are also able to control the temperature of your indoor space that you can relax easier.
