Can You Put Your Hot Tub Inside A Greenhouse?

Have you ever wondered if you could put your hot tub inside your greenhouse. How would the hot tub benefit by being placed in a greenhouse? What would happen with the plants inside the greenhouse? I have a cool article talking about the pros and cons of having your hot tub in a greenhouse. You can read it here.


Condensation is likely to happen especially on your windows and walls around the tub. This is because of the varying temperatures inside and outside the tub. Obviously, the hot tub will be hot while the room temperature will likely be colder.

This will probably not be an issue with your hot tub if it has an insulated cover. When not using the tub, you’ll likely cover it thus preventing condensation from happening. If you don’t have a cover, then condensation will most likely be an issue.

If you’re installing your hot inside a pool hall, then condensation will also not be an issue because of an air handling unit.

To combat all the aforementioned issues, it is prudent to consider installing a high-tech kind of ventilation. This goes miles to balance the temperatures inside the room hence preventing any form of damage. Ceiling fans are effective at providing great circulation indoors.

Installing a vapor barrier is also necessary to ensure your wall studs do not dry rot. Because of the steam environment inside, it would be wise to be cautious with the kind of walls you install. Water-resistant types of drywall such as green board or rot-resistant wood such as cedar are excellent choices.

Drainage and Flooring

Another important aspect that you need to consider when installing an indoor hot tub is drainage and flooring. When climbing from your hot tub, some water will get to the floor. For this reason, avoid slippery flooring.

The kind of flooring you choose should not only maintain excellent drainage but must also have great traction when wet.

Because of their proneness to rot, you shouldn’t even consider wood and carpet surfaces. Another terrible option would be Astroturf because water seeps beneath it.

The best flooring option is non-slip, matte-finish tiles. For effortless clean-up and drainage, ensure you put up a floor drain.

Water Access

Most hot tubs do not require any external plumbing. However, while that might be the case, effortless access to water to fill the hot tub is still necessary. When planning the indoor space to slide your tub into, consider having a water spigot close by.

Access to Getting Hot Tub in and Out

Well, this might not seem like big of a deal to many people but actually is. You should consider how to get your hot tub in and how to get it out.

Quite often, I’ve seen people that have installed a hot tub during the build of a house. This is great as all they need to do is lift it right into place and build around it. It is superb when the hot tub is working but not so great when you need it out.

Of course, the last thing you want is to cut your hot tub into pieces just to get it out. You also don’t want to remove a wall or window to get it out.

Therefore, I’d suggest that you not only consider how to get it in but also out when installing your indoor hot tub. The best way to do it is to have a door that fully opens. You can install a garage door or patio door that opens fully.

A glass bi-fold door can also be handy in such a case. Simply put, you just need a door or something that folds or opens completely for purposes of getting your indoor hot tub out when need be.

Chlorine Alternative

Within an enclosed area, the smell will be compounded. This is especially true if you use chlorine in your hot tub. So how do you run yours with chlorine?

One of the alternatives you can consider is bromine. In addition to boasting less smell, it is also friendly to the hair and skin.

You could also consider odorless solutions such as Silk Balance.

Why You Should Consider an Indoor Hot Tub

Having established that it is okay to install a hot tub indoors, I think it is prudent to learn what are some of the advantages of having your hot tub indoors over outdoors.

Well, indoor hot tubs are better than outdoor ones because of:

  • Privacy
  • Convenience
  • Protection


Privacy is the major advantage of owning an indoor hot tub. Regardless of your neighborhood, it is important to be private in some of your affairs. This is particularly true if other properties overlook your garden or outdoors.


Convenience is another strong attribute of indoor hot tubs. With one, you don’t have to leave the house to access relaxing and warm water.


Unlike with outdoor hot tubs that you have to be constantly worried about the weather, with the indoor ones, that’s the last thing you’ll do. It will never be too sunny or hot to wear sunscreen or even too wet or cold to freeze in water.

Your cabinet and cover will always remain undamaged by harsh elements. On top of that, you’ll also not have to worry about airborne allergens.

Final Words

Is it ok to put a hot tub indoors? Yes, it is.

The only thing you need to be careful about are the factors I highlighted above. When you take care of everything laid out on this primer, you can rest assured that you’ll enjoy an incredible hot tub experience indoors.
