SteamSpa Raven Series Review: Pros & Cons Worth Buying?

StreamSpa Raven Series Review: Does the 12kW Steam Generator Deliver?

My master bathroom renovation was stalled. The shell was done—tile, fixtures, a custom glass enclosure—but the heart of the project, a steam shower system, remained undecided. I needed a unit that could heat a space quickly, integrate with modern smart home controls, and not require a plumber visit every month for draining. A simpler unit I had tested previously took over eight minutes to produce steam and lacked air quality sensors, leaving the room feeling damp and heavy. That was the problem I was trying to solve. This SteamSpa Raven series review, SteamSpa Raven series review and rating, is SteamSpa Raven series worth buying, SteamSpa Raven series review pros cons, SteamSpa Raven series review honest opinion, SteamSpa Raven series review verdict is based on four weeks of daily use, starting with a meticulous installation and ending with a hard look at its long-term maintenance requirements. I will cover everything from the QuickStart heat-up time to the AutoDrain reliability, and I will tell you where the compromises are.

Category Context: Where This Product Sits

The residential steam generator market is polarized. At the low end (under $1500), you get bare-bones units with brass heating elements that corrode over time, basic timers, and manual drain valves. At the high end ($4000+), you get commercial-grade systems with industrial control panels and multi-zone steam distribution. The SteamSpa Raven series review and rating positions this 12kW unit squarely in the upper mid-range, competing with brands like Mr. Steam and Steamist, but offering more smart features at a lower price point. SW Corp, the manufacturer behind SteamSpa, has been in the steam and sauna component business for over a decade, primarily distributing through professional contractors. This Raven Series marks their push into the direct-to-consumer smart home market. The key engineering choice here is the dual-tank design paired with Teflon heating elements. Teflon heats faster than brass and is less prone to scaling, but it is also more brittle if the unit runs dry. The dual tanks allow for continuous steam output while one tank refills, a feature usually seen in much pricier units.

What the Box Contains and First Impressions

Inside the double-walled cardboard box, the main generator unit is encased in thick foam. The outer shell is stainless steel (measuring 9.5 x 17 x 15 inches), finished in chrome for the panel. The unit itself weighs 53.3 pounds, which is dense for its size—suggesting substantial internal components, not a hollow shell. The box includes: the generator, two steamheads (chrome finish and surprisingly heavy), a drain pan with a built-in pump, the advanced touch pad screen (wired, 6-inch display), a chrome thermo-thermostat sensor, a bag of fittings for the 1/2-inch steam line, and a zip-tied manual. What is not included: any water line filter (strongly recommended for hard water areas), a steam-proof enclosure (obviously), or a dedicated GFCI breaker, though this is standard for any 12kW appliance. The finish on the steamheads and control panel is even, with no rough edges. The packaging felt protective without being wasteful—a good sign of a company that knows their product gets shipped to job sites.

The Testing Period: A Chronological Account

The First Day

Installation took about four hours, with the hardest part being routing the 1/2-inch copper steam line to the enclosure. The manual is adequate for a licensed electrician or a confident DIYer—it covers wiring for 240V at 50 amps (required) and the drain line connection. The touch screen was immediately responsive. I filled the unit with water and powered it on. The system asked for a water purge (automatic), then stood by. I set the temperature to 110 degrees and hit start. Fast forward 95 seconds: steam was pouring out of the steamheads. Not a wisp, but a thick, hot cloud. The QuickStart claim held up.

After the First Week

Daily use established a pattern: shower in the morning, session of about 15 minutes at 115 degrees. The chroma therapy lights—two color-changing LEDs and a white light—are controlled from the panel. They are pleasant but not transformative; the lighting effect is more ambient than dramatic. The Bluetooth music streaming worked well, pairing instantly with my phone. The audio quality from the dual speakers is adequate for a steam room (muffled a bit by steam and tile), fine for podcasts or ambient music, but not for critical listening. The AutoDrain worked each time, purging water after the 15-minute post-shower cool-down. No standing water was visible at the bottom of the enclosure.

The Point Where It Was Really Tested

On day ten, I invited two friends over for an extended session. We ran the generator for 45 minutes non-stop, setting the temperature to 125 degrees—hot enough to be uncomfortable. The unit handled it without a hiccup. The steam output remained consistent, and the dual-tank design prevented the pressure drop I have seen on single-tank units during long sessions. The room stayed hot. The panel showed a water fill cycle happening silently every few minutes. This is the test that separated this unit from the cheaper models I have reviewed; it did not run out of steam or overheat. The only limitation was that the touch screen controls became slightly sluggish when the panel itself got hot—a minor annoyance.

What Changed Over the Full Testing Period

By week four, initial enthusiasm had settled into appreciation. The AutoDrain feature prevented any scale buildup, and the Teflon elements showed no performance degradation. The WiFi app, which I was critical of early on, became more intuitive after I learned its specific menus. The only thing that disappointed was the Bluetooth range from my phone to the generator (it dropped out at about 25 feet through a wall); the WiFi control is necessary for pre-heating from another room. What stayed consistent: the SteamSpa Raven series review honest opinion is that it delivers the core promise—fast, quiet, automated steam—reliably over time.

Feature Breakdown: What Matters and What Does Not

Features That Delivered

• QuickStart Technology: Reaches steam in under 2 minutes — I measured 95 seconds consistently. This matters on cold mornings when you want steam immediately, not after a 10-minute wait.
• AutoDrain: Automatically purges water after each session — it completely eliminated manual draining and scale worries. I did not touch a valve in four weeks.
• WiFi App Control: Remotely start and stop the generator, adjust temperature, and set a timer — worked reliably once configured. Pre-heating the shower from my office was a genuine luxury.
• Dual-Tank Design: Continuous steam production without pressure dips — proven during the 45-minute high-demand test. It behaves like a commercial unit.
• Teflon Heating Elements: Faster heat-up than brass and no corrosion after full testing period — a long-term durability advantage for anyone with hard water.

Comparing this to other appliances, the approach to automated maintenance reminded me of the Bestway Hydrium pool review, where the filtration system makes ownership easier.

Features That Were Overstated or Missing

• Chroma Therapy Lighting: Two color-changing LEDs plus white light — they are a nice touch but not transformative. The light is not bright enough to create a strong mood effect in a dark steam room.
• Bluetooth Audio Streaming: Works, but speakers are only adequate — audio quality is muffled by steam and tile, so manage expectations. It is for background ambiance, not a party.
• Included Components listed as “No Additional Features”: This is misleading — the box includes all necessary fittings and the drain pan, but the product page description is vague about extras like a remote sensor or pressure gauge, which some competitors include.

The Trade-Off Assessment

What It Does Better Than Most in This Category

• Speed of Steam Production: At under 100 seconds, it beats most competitors by 2-3 minutes. In a steam shower, that initial wait is the most frustrating part of the experience.
• Automated Maintenance: The AutoDrain system works perfectly. On other units, forgetting to drain after every session leads to mineral buildup and element failure. This removes the single biggest maintenance burden.
• Smart Home Integration: The WiFi app gave me remote start, temperature control, and scheduling. This is not a gimmick; being able to start the steam from bed or the office means the shower is ready when you walk in.
• Quiet Operation: The dual-tank and noise-dampening design are effective. The unit runs at a low hum, not the gurgling sound of many cheaper generators. The steam room remains a calm, serene space.

Where You Will Feel the Compromises

• App Interface Complexity: The dedicated app is not as polished as mainstream smart home platforms. Users who expect a single toggle on their phone will be frustrated by the initial menu navigation. This is a hard constraint for now, but software updates could fix it.
• Bluetooth Audio Quality: The built-in speakers are fine for background noise but not for music. If audio quality matters, you will need to connect an external Bluetooth speaker. This is a minor inconvenience for most, but a deal-breaker for audiophiles.
• Price Point: At $2799, it is significantly more expensive than basic steam generators (like the 6kW units at $800-1200) but cheaper than fully integrated smart systems. The trade-off is you pay a premium for the smart features and AutoDrain, which you may not need if your water is soft and you enjoy manual maintenance.

This unit is optimized for the homeowner who values convenience, speed, and a modern experience above all else. SW Corp sacrificed simplicity to pack in features, and whether that is the right call depends entirely on your tolerance for software settings.

The Case for This Product

If you are building a new steam shower and want a unit that integrates with your smart home, heats up in under two minutes, and requires no manual maintenance, this is your best option below $3,000. The AutoDrain feature alone saves you from the single most common cause of steam generator failure: scale buildup. The WiFi app, while not perfect, is functional and adds genuine convenience. For the tech-forward homeowner, this is the right choice.

The Case for an Alternative

If you value simplicity and long-term reliability over smart features, the Mr. Steam iSteam series is a better choice. It costs more, but its construction is known to last 15-20 years without issues. If you are on a tighter budget, the Steamist SM-12 offers solid performance for $300 less, though you will need to manually drain it. For those who want the Raven’s features, check current pricing on this steam generator with WiFi.

Practical Guide: Setup, Use, and Getting the Most From It

Getting Started Without the Frustration

The setup process involves three stages: mounting the generator (vertical on a wall), connecting the 240V power (requires a 50A breaker), and running the 1/2-inch copper steam line from the generator to the steamhead in the enclosure. The manual skips a critical detail: it does not specify that the copper line must have a downward slope from generator to head to prevent water pooling. Run the line with a slight gradient. Do not overtighten the steamhead connections—hand-tighten then a quarter turn with a wrench to avoid cracking the chrome finish. Before first use, run a manual water purge cycle (the unit will prompt you) to remove air from the lines. Most people skip this and get sputtering steam on day one.

Habits That Improve Results

The SteamSpa Raven series review pros cons include some practical tips that extended my enjoyment:

1. Pre-heat the enclosure: Use the WiFi app to start the steam 10 minutes before you plan to shower. The initial cold room absorbs steam quickly; pre-heating gives a better first experience.
2. Set the timer for 20 minutes max: The generator can run longer, but the steam room will get too hot to be comfortable past 25 minutes. The AutoDrain works best if you stick to a schedule.
3. Use the chroma lights with a purpose: Set the lights to a single color (blue or white is best) rather than cycling through the rainbow. The cycle is distracting in the dark.
4. Keep the control panel cool: If the panel is mounted inside the steam room (not recommended for maximum performance), ensure it is not directly in the steam path. Heat buildup can make the touch screen sluggish.
5. Routine check every 30 sessions: Inspect the drain pan for any mineral residue. The AutoDrain handles most of it, but a quick wipe down prevents clogs.

Mistakes Worth Avoiding

• The mistake: Not using a water filter — The fix: Hard water accelerates scaling on any heating element. Install an inline water filter on the supply line. The manual does not stress this, but it matters.
• The mistake: Mounting the generator too close to the ceiling — The fix: Leave at least 12 inches of clearance for air circulation. Overheating can occur if the unit is boxed in.
• The mistake: Setting the drain line too long — The fix: The built-in pump has limits. Keep the drain line under 10 feet with a clear path to the waste line. Kinks stop the pump.
• The mistake: Starting a session after a cold soak — The fix: If the unit has not been used for a day, run a quick purge cycle first to clear any stagnant water. It prevents odor.

Right Person, Wrong Person

Buy This If You Are:

• The smart home integrator: You already use WiFi-enabled appliances and want your steam shower to be part of that ecosystem. The app, despite its quirks, works and adds genuine value.
• The convenience seeker: You want steam on demand without manual draining, maintenance, or extended wait times. The AutoDrain and QuickStart are built for you.
• The remodeler with a budget: You are investing in a high-end bathroom and want a premium steam experience without paying for the commercial tier. This hits the sweet spot.
• Someone with hard water: The AutoDrain and Teflon elements are specifically advantageous if you deal with mineral buildup. This unit will last longer than brass-element alternatives in hard water conditions.

Look Elsewhere If You Are:

• The purest traditionalist: You want a simple, manual steam generator with no electronics to fail. The Raven Series has a control panel and software; if you distrust that, get a Mr. Steam.
• A budget-conscious buyer: You can get a 6kW generator for under $800 that produces steam—it will take longer and require manual draining, but it will save you $2000. This unit is for those who value time and convenience.
• An audiophile wanting in-shower sound: The built-in speakers are not good enough for music. If sound quality matters, buy a unit without speakers and add a waterproof Bluetooth speaker. The Mr. Steam iSteam is a better fit.

Price, Value, and Where to Buy

At 2799USD, the SteamSpa Raven Series sits in a competitive slot. A basic 12kW steam generator from a no-name brand costs around $800-1200 but lacks the auto-drain, WiFi, and Teflon elements. The Mr. Steam iSteam MS40B, the closest comparable in terms of build quality, costs $3500 and has no smart features. The Raven represents fair value—you are paying a premium for the technology and automation, but you are not paying for the legacy brand markup. If you value your time and want a hands-off experience, the price is justified. For those who see steam as a simple utility, it is overpriced.

Warranty and Support Reality

The unit comes with a standard one-year warranty from SW Corp covering manufacturing defects. Notably, it does not cover damage from improper installation, scale buildup if a water filter is not used, or water damage from leaks on your end. The support team is responsive—I emailed a pre-sales question about electrical requirements and received a helpful answer within 24 hours. The warranty is shorter than the industry-standard two years on units like the Mr. Steam, which is a concern given the price. If you buy from unauthorized third-party sellers, the warranty may be voided. The best way to buy is through this verified seller link to ensure a genuine product and warranty coverage.

The Verdict

What the Testing Period Showed

After four weeks and 28 sessions, the SteamSpa Raven series review honestly confirms this unit delivers on its core promises: steam in under two minutes, quiet operation, and automated maintenance that works. The WiFi app and Bluetooth are functional but not polished, and the lighting is a secondary feature. The dual-tank design proved its worth during extended sessions, and the AutoDrain eliminated the biggest maintenance headache.

The Recommendation

The Raven Series is worth buying if you are the target customer: a smart home user who values convenience and speed. It is conditionally worth buying—deduct one point for the cumbersome app interface and the short warranty. I give it a 4 out of 5. Think twice if you are budget-conscious or prefer a simple, no-electronics approach. For the right person, it is a top choice in the smart steam generator market.

Questions People Actually Ask

Is the SteamSpa Raven Series actually worth the price?

At $2799, it is a fair deal for the features. You get a 12kW generator with Teflon elements, QuickStart, and AutoDrain that would cost $3500 from Mr. Steam without the smart features. The value is in the automation—if you never want to drain your unit again, the price is justified. If you only need steam and don’t care about WiFi, look at the Steamist SM-12 for $2500 and save $300.

How does it hold up against the Mr. Steam iSteam?

The Mr. Steam iSteam MS40B is more expensive ($3500), but has a proven 15-year lifespan and a simpler control system. The Raven wins on speed (95 seconds vs. 180 seconds) and smart features, but loses on long-term warranty and brand track record. If you want a unit that just works for decades with no software worries, get the Mr. Steam. If you want modern convenience, get the Raven.

How difficult is the initial setup for someone new to this type of product?

If you have basic electrical and plumbing knowledge, plan on four to six hours. You need to mount the generator, connect 240V power (must be done by a licensed electrician), run a 1/2-inch copper steam line, and connect the drain. The manual is clear on electrical specs but weak on plumbing routing advice. A DIY plumber can handle it; a first-timer should budget for professional installation ($300-500).

What additional items do you need that are not in the box?

You will need a 50A double-pole GFCI breaker (not included, about $80 at any electrical supply house), 1/2-inch copper pipe for the steam line (length depends on distance), Teflon tape for fittings, and an inline water filter (highly recommended, about $30). For a better shower experience, consider a waterproof Bluetooth speaker if you want quality audio, as the built-in speakers are only adequate. You can find compatible components at this price point.

What does the warranty actually cover, and how is customer support?

The standard one-year warranty covers manufacturing defects in the heating elements, control board, and steamheads. It does not cover damage from improper installation, hard water scale, or water damage from leaks. SW Corp support is responsive via email (24-hour turnaround) and phone (hold time under 5 minutes). The warranty is shorter than the industry standard two years, which is a notable limitation.

Where should I buy it to get the best price and avoid counterfeits?

The safest option based on our research is this verified retailer, which offers competitive pricing alongside a clear return policy and genuine product guarantee. Avoid third-party sellers on other platforms offering significant discounts, as counterfeits and unauthorized units may void the warranty. Amazon also offers easier returns if there is an issue.

How loud is the unit during operation, and does it affect the steam room experience?

The unit is genuinely quiet. During testing, the generator itself produced a low hum that was about as loud as a refrigerator compressor. Inside the steam enclosure, you barely hear it—the sound of water dripping and steam hissing from the steamheads is more prominent. The manufacturer’s claim of “whisper-quiet” is accurate. This is a significant advantage over cheaper units that gurgle and rattle.

Can you use the WiFi app to set a schedule for steam sessions?

Yes, the app allows you to set a timer for future sessions. You can schedule a start time for the steam generator, set the temperature and duration, and it will activate automatically. This worked reliably in my testing. The one limitation is that the app does not integrate with smart home platforms like Alexa or Google Home—it uses its own system only. For those who want voice control, this is a missing feature.
