Best Steam Shower Generator: Complete Guide

Spending more doesn’t mean you’ll get more in return. At least not all the time. But buy wisely, and you’ll get a handsome reward. Such is the case with steam shower generators. But then, what’s the trick? Well, below are key considerations before you take the plunge.

Power Rating

Steam shower generators are rated in kilowatts. A higher rating equals more steam and better coverage. For instance, a 10kw model generates more steam and heats more space than a 5kw version. But there’s a price to pay as larger models consume more power. Well, the reverse is true for a smaller unit. It generates less steam, heats a small area, but consumes less power.

Shower Room Size

A higher power rating accommodates a large bathroom. A smaller power rating, on the other hand, is ideal for a small bathroom. Though true, it’s pretty general.

Well, to get to the specifics, you need the correct sizing. Check the cubic feet coverage of the steam generator and divide it by two. Are you wondering why we divide by two? Well, manufacturers give the nominal volume that might not be as efficient. Hence, we divide it by two for peak performance.

Once you get the result, cross-check with the size of the enclosed space of your shower room. If it’s higher or equal to the shower room size, you’re good to go. However, more is always better.


The size of your shower system will also dictate how far or close you need to install the steam generator. For a bathroom with limited space, you might need to install it outside. Or maybe in another spot, such as the basement or attic.

How far or near also depends on the manufacturer’s specs. Some sit close while others can be 20 or more feet away.

Automatic Drainage

It’s not a must-have. Nevertheless, it’s a convenient feature to have a shower drain. It flushes out any water to avoid mineral build-up, hence providing more lifespan.

Built-in Timer

How long will the steam generator provide steam for your shower? Some offer an endless stream of steam. Other models only generate steam for shorter periods of time. So, to avoid any surprises, consider one with a built-in timer. That way, you’ll know when the steam is about to run out.

Wait Time

Time is precious, and each minute counts. Hence, you want a steam generator that kicks on and pushes steam into the shower without the long wait. 5-10 minutes of waiting doesn’t hurt. Anything more than that is frustrating. High-end generators, such as Kohler K-5529, produce steam in seconds.


Accessories will help you avoid extra expenses when setting up the generator. Hence, consider a model that comes complete with accessories, such as the control panel. Chroma therapy shower lights, though not a must, will improve your shower experience. Generally, the more the accessories, the better.


Fitting size dictates the size of the pipe and connections you’re going to use. Hence, consider the size of the steam head, inlet, and drain valve. Fitting size pipes tend to vary across different models. Among the most common sizes are 1/2-inch and 3/4-inch.


A warranty cushions you from possible defects. One that covers your generator for at least one year should be okay.

Mineral build-up in the boiler is the main culprit to a shorter lifespan. And hard water is the major contributor to mineral build-up. Hence, using soft water will prolong the lifespan of your generator.
