Use This Easy Steam Shower Generator Sizing Calculator
Are you planning to install a steam shower in your home but need help choosing the right size steam generator for your needs?
A steam shower can offer numerous health and wellness benefits, such as improved circulation, relaxation, and stress relief. However, choosing the wrong size steam generator can lead to subpar performance, unnecessary energy usage, and even potential safety hazards.
To fully enjoy the benefits of a steam shower, it’s crucial to steam shower generator sizing right for your specific shower space and usage needs.
In this article, we’ll guide you through the steps to determine the right size steam generator for your steam shower, including how to calculate the BTUs and kW needed, factors to consider, and using a sizing calculator.
Use the steam generator sizing calculator
A steam generator sizing calculator takes into account the steam room dimensions, ceiling height, and other factors to provide an accurate calculation of the BTUs and kW rating needed for the steam generator based on the cubic footage of the enclosure. This information is essential in determining the size of the steam generator required to meet your specific needs.
Before doing anything, measure the ceiling height, length and width of the shower enclosure. The materials and exterior wall of the steam room enclosure also factor into the amount of steam you need, but the calculator will handle that. For instance, if you have a couple of exterior walls this will dramatically increase how much steam you need and will impact the steam generator sizing.
Rather than make the calculations yourself, use the calculator below. To use it, fill in the fields and use the dropdown menu for other factors, such as the external walls.
Once you have the total room volume, check that number against the steam shower generator sizing chart below it to see what the correct generator is for you.
Total Room Volume:
| Generator Size | Total Room Volume Range |
|---|---|
| 7KW Generator | 101-250 |
| 10KW Generator | 251-450 |
| 12KW Generator | 451-550 |
| 15KW Generator | 551-675 |
Here is a list of the shower enclosure materials that will impact how much steam your generator sizing:
- glass block walls
- porcelain tile
- natural stone slabs
- glass tile
- glass panels, ie doors
- formed plastic
- ceramic tile
- cast iron tub
In addition to exterior walls and ceiling height, these materials will either cool down the steam that fills the steam room, or not heat up quickly. Even some steam and sauna products will affect the amount of steam needed such as a bench. Make sure to account for the profound effect when using the calculator for steam generator sizing.
How to choose the right steam generator for a steam shower
When researching brands and models, consider the features and options available. Some generators come with additional features, such as programmable settings, remote control, and temperature sensors. These features can enhance your overall experience and make using the steam generator more convenient.
Additionally, pay attention to the warranty offered by the manufacturer. A good warranty can provide peace of mind and protect your investment. Look for warranties that offer coverage for the parts, labor, and electrical components.
The list below should help you decide on the right steam shower generator.
Residential steam shower generator vs commercial
There are two different types of steam shower generator to choose from. Without them being specifically labeled, one is for homes and another is for steam rooms in a commercial setting such as a gym or hotel. The way to know the difference is through the voltage.
A 240V system typically refers to a single-phase electrical system that delivers power using two “hot” wires and a neutral wire. The voltage between the two “hot” wires is 240V, which is commonly used for residential and light commercial applications in North America.
On the other hand, a 208V system refers to a three-phase electrical system that delivers power using three “hot” wires and a neutral wire. The voltage between any two “hot” wires is 208V, and this type of system is commonly used for larger commercial and industrial applications for enclosures with a high cubic footage.
While a 240V steam shower generator system can handle many residential and small commercial applications, a 208V system is often used for larger equipment and electrical loads due to its higher voltage and ability to distribute power across three phases.
However, it’s important to note that the specific voltage and phase requirements for a particular steam room will depend on the steam shower generator being used and the electrical code requirements in your area.
Must have features in a generator
- Power output: The steam generator’s power output, measured in watts or kilowatts, should match the size of your steam shower and the desired temperature and steam output.
- Control options: Look for steam generators that come with user-friendly controls, such as digital displays and programmable settings.
- Safety features: Safety features like automatic shut-off, low water sensors, and pressure relief valves are essential for safe and reliable operation.
- Water quality management: High-quality steam is essential for a good steam shower experience, so look for steam generators with features like automatic drain and flush systems, water filtration systems, and water level probes.
- Noise level: Some steam generators can be noisy, so look for models with low noise levels or soundproofing features such as anti-hammer, low voltage water Solenoid valves.
- Material quality: Look for steam generators made from high-quality, corrosion-resistant materials such as stainless steel that can withstand the humid environment of a steam shower.
- Warranty: A good warranty can provide peace of mind and protect your investment. Look for warranties that offer coverage for the parts, labor, and electrical components.
