How Long Do Bathtub Refinishing Fumes Last?

As opposed to replacing it totally, refinishing your bathtub might save you a significant amount of money. However, a common question that emerges among homeowners is this: how long do the fumes from refinishing a bathtub remain in the home?

The answer to this issue can have far-reaching implications, from the timeline for when you can safely use your bathroom after the refinishing is complete to the measures you should take and even the effects on your home’s surroundings. To keep your house secure and odor-free, this manual delves deeply into this important topic.

How Long Do Bathtub Refinishing Fumes Last?

Bathtub refinishing fumes are typically strongest for the first few hours post-application. However, you may continue to notice a lessened odor for up to 24 hours as the finish fully dries. However, several factors influence this timeline, including:

  1. The Type of Coating Used
  2. Ventilation in the Bathroom
  3. Temperature and Humidity

Let’s examine these points further.

The Type of Coating Used

In general, there are three main types of coatings used in bathtub refinishing: Epoxy, Acrylic, and Polyurethane. Each has a distinct smell and drying time, which directly impact how long the fumes last.

Type of CoatingDrying TimeSmell Duration
Epoxy1-2 days24-48 hours
Acrylic3-4 hours24 hours
Polyurethane6-8 hours48-72 hours

The coating material used plays a crucial role in determining the smell duration, so always consult your refinishing professional about this aspect.

Ventilation in the Bathroom

Ventilation is a significant factor in determining how quickly the bathtub refinishing fumes dissipate. Better-ventilated bathrooms will have quicker evaporation rates, leading to a reduction in the smell.

Well-Ventilated Bathrooms: Essential for Clean Air

Well-ventilated bathrooms provide a clean, fresh environment. They effectively eliminate unwanted fumes generated by activities like bathtub refinishing. Ideally, this process should last between 24 to 48 hours, ensuring that the air remains pure and invigorating.

Poorly-Ventilated Bathrooms: Risks of Stagnant Air

On the other hand, bathrooms with poor ventilation can create a stagnant and burdensome atmosphere. The fumes generated during refinishing tasks do not dissipate easily and can linger for up to 72 hours. This heavy air waits for the fumes to naturally decrease, restoring freshness at a much slower pace.

Temperature and Humidity

Like most chemical reactions, temperature and humidity can influence the drying time of the refinishing coating, and consequently, how long the fumes last. Higher temperatures and lower humidity tend to speed up drying, thereby reducing fume duration.

Dealing with Bathtub Refinishing Fumes

Understanding how long bathtub refinishing fumes last is essential, but knowing how to deal with these fumes is just as crucial. Here are a few tips to make the process less intrusive on your everyday life: Read this post; Difference Between Reglazing And Refinishing A Bathtub

Proper Ventilation for Bathtub Refinishing

During the bathtub refinishing process, it’s crucial to ensure adequate ventilation to disperse harmful fumes. This can be achieved by opening windows and doors to create a path for the fumes to exit your living space. Using fans can further enhance the effectiveness of ventilation, speeding up the removal of strong odors.

Using Air Purifiers

To help maintain indoor air quality during bathtub refinishing, consider using air purifiers. These devices work to cleanse the air, reducing the concentration of particles and odors that might cause discomfort. While air purifiers won’t eliminate the strong smell immediately, they significantly minimize it, making your home environment more bearable during the refinishing process.

Scheduling Bathtub Refinishing

Timing is a crucial factor when planning for bathtub refinishing due to the strong odors it can produce. It’s advisable to schedule the refinishing at a time when you can leave your home, avoiding direct exposure to the fumes. By carefully planning, you can mitigate the impact of these odors on your comfort and health.

Are Bathtub Refinishing Fumes Dangerous?

Yes, bathtub refinishing fumes, particularly those containing methylene chloride, are indeed dangerous. These fumes can lead to unpleasant symptoms like ear irritation, excessive drooling, and mucous membrane irritation. It’s crucial that anyone involved in the refinishing process wear protective gear, including face masks and respirators, to safeguard their health.

Here are three main reasons why these fumes can be harmful:

  1. Health Hazards: Prolonged or frequent exposure to these fumes can lead to several health problems, such as headaches, dizziness, nausea, and even damage to the nervous system, liver, and kidneys. In severe cases, exposure can result in unconsciousness or death.
  2. Air Quality Decline: These fumes can significantly reduce indoor air quality, leading to uncomfortable living conditions and potentially exacerbating pre-existing respiratory conditions like asthma.
  3. Environmental Concerns: VOCs contribute to air pollution and climate change. Therefore, their use poses not only an immediate threat to individual health but also a longer-term danger to our environment.

Components of Bathtub Refinishing Fumes

The table below lists some of the most commonly used chemicals in bathtub refinishing products and their associated risks.

Methylene ChlorideAcute exposure can cause headaches, dizziness, confusion, and in high concentrations, can lead to unconsciousness or death. Long-term exposure may cause cancer.
TolueneProlonged exposure can lead to tiredness, confusion, weakness, memory loss, nausea, and loss of appetite. It can also damage the liver and kidneys.
XyleneHigh levels can lead to headaches, lack of coordination, dizziness, confusion, and changes in one’s sense of balance. Long-term exposure may affect the liver, kidneys, and lungs.


How long does tub reglazing smell last?

Tub reglazing odor can linger for about 24-48 hours, depending on ventilation in your bathroom.

How long do you have to stay out of the house after a bathtub is refinished?

Post-refinishing, you should stay out of your home for at least 24 hours to allow the new surface to dry and fumes to dissipate.

Is it safe to take a bath in a refinished bathtub?

Yes! Once a bathtub is properly refinished and completely dried, it’s safe for you to take a bath in it.

How do you get rid of the smell of resurfacing in a bathtub?

Getting rid of the smell after resurfacing a bathtub requires good ventilation. Open windows, use fans, and consider an air purifier. The smell should dissipate in about 1-2 days.
