This kit gives you the core components you need to get started. It includes the SimpleSteam Generator, the Square Digital System Control, and the Square Steam Head. Everything is finished in a modern matte black.

You get a 10kW generator in this kit. That is a good size for many standard shower enclosures.

If you are planning a larger space, the same generator line also comes in 4, 6, 7.5, 12, and 15 kW options. This means you can match the power to your specific bathroom layout. The generator itself has a compact design. This is a practical feature. You can install it in a vanity cabinet, a nearby closet, or even an insulated attic or basement. It does not need to take up precious floor space in your bathroom.

The kit includes a 35-foot cable to connect the control to the generator.

The digital control is square and modern, so it will fit nicely into a tiled wall. The steam head is also square, matching the control for a clean look.

You should know about one extra item. Delta recomends a generator pan and auto drain, model 5GA-PAD-240, for this system. That part is not included in the kit.

Steam Shower Generator Buying Guide

A steam shower generator purchase depends on matching steam output capacity to your enclosure’s cubic footage. Get this wrong, and you’ll either wait forever for steam or waste energy. But that’s just the start. You also need to think about controls, water quality, and where you’ll install the unit. Let’s break it down so you don’t end up with a generator that fights your bathroom instead of helping it.

Steam Output Size

First, measure your shower’s length, width, and height. Multiply them together to get cubic feet. Most generators list the max cubic footage thay can handle. But here’s the catch—if you have tile, glass, or high ceilings, you might need a bigger unit. Tile and glass absorb heat, so your generator works harder. A good rule: pick a generator rated for 10-20% more space than you measured. That way, you get steam fast, not after a 15-minute wait.

Control Panel Type

Do you want a simple knob or a digital touchscreen? Basic controls let you turn steam on and off. That’s fine if you don’t mind guessing the temperature. Digital controls give you precision—set the exact temperature, timer, and even a pre-soak delay. Some even connect to your phone. Think about your daily routine. If you just want quick steam after a workout, keep it simple. If you like to set the mood with lighting and music, go digital.

Water Quality Considerations

Hard water is the enemy of steam generators. Mineral buildup clogs the heating element over time. If your area has hard water, look for a generator with a self-cleaning or descaling feature. Some models have a drain valve so you can flush it out monthly. Skip this step, and you’ll be replacing the unit in a few years. A small upfront investment in a better generator saves you from a headache later.

Installation Location

Where does the generator go? Most fit inside a cabinet or closet near the shower. But they need clearance for ventilation—don’t cram it in a tight spot. Some generators are rated for indoor or outdoor installation. If you’re tight on space, check the dimensions before buying. You don’t want to find out it won’t fit after it arrives. Also, make sure the steam line can reach your shower without too many bends. That keeps the steam flowing smooth.

Frequently Asked Questions About Steam Shower Generator

What size steam shower generator do I need?

You need teh right size for your steam shower. Generators are rated by cubic feet of space. Measure your shower’s length, width, and height. Multiply them. That gives you the volume. Most generators list their max cubic feet. Pick one that matches or slightly exceeds your number. Bigger is ok. Too small means weak steam.

What is the typical power requirement?

Steam generators run on electricity. Small ones need a 15-amp, 120-volt circuit. Larger ones need 240 volts. Check your home’s electrical panel first. You might need an electrician to run a new line. Always check the product specs for voltage and amperage.

Do I need special plumbing for the drain?

Yes. Steam generators produce condensation. They have a drain line that must go to a floor drain or a sink drain. The drain should be lower than the generator. This allows gravity to work. Use a p-trap to prevent odors. Some units have a self-cleaning feature. That helps reduce mineral buildup.

How long does it take to heat up?

It varies. A small 6kW generator heats a shower in about 10–15 minutes. Bigger units take a bit longer. The water in the boiler must reach the right temperature. You can set a timer on some models. That way, it’s ready when you step in. Expect a warm-up peroid of 10 to 20 minutes.

Can I install it myself?

Maybe. If you are handy with electricity and plumbing, yes. But it involves wiring a high-voltage circuit and connecting water lines. Most people hire a professional. It saves time and avoids mistakes. Always follow local building codes.

What about maintenance?

Minimal. Descale the unit every few months. Use a vinegar solution or a special descaling product. Check the drain for clogs. Replace the steam head if it gets blocked. Some generators have a flush feature. That makes it easier. Keep the area around the generator clean and dry.

Is a steam shower generator loud?

They make some noise. You hear water boiling and steam moving. But most modern units are well-insulated. The noise is low and steady. It should not be bothersome. Place the generator away from the shower if you want it quieter.

Our Final Words

Your home spa experience is just a quality steam generator purchase away. You don’t need a fancy bathroom remodel to enjoy teh benefits. A good unit gives you steady steam heat and reliable performance. Think about how much you’ll save by skipping the gym spa or day trips. Just set your preferred temperature and enjoy the soothing warmth after a long day. It’s really that simple. Take your time measuring your space and checking the power requirements. Most modern units are compact enough to fit in a closet or crawl space. You’ll wonder why you waited so long.

Remember to check the warranty and customer reviews before you buy. A reliable steam shower generator can last for years with minimal upkeep. It’s a smart choice for anyone who values comfort and convienence at home. So go ahead and make that upgrade. Your bathroom can become your favorite place to unwind. No complicated installation tricks are needed. Just follow the instructions and you’ll be set. You deserve a space that works for you every single day.
