FOGATTI’s InstaShower 9 Pro is aimed at RV owners who want stronger, steadier hot water than a small tank heater usually provides.
If you are trying to support daily showers, kitchen use, and fewer temperature swings, this FOGATTI InstaShower 9 Pro RV Tankless Water Heater review is about fit, not hype.
InstaShower 9 Pro Review Summary
The FOGATTI InstaShower 9 Pro RV Tankless Water Heater makes sense for buyers who want a higher-output RV water heating setup with a built-in mixing tank, a remote controller, and a package that includes key install accessories.
It is best for RVers who care about comfort and consistency more than minimalism, especially if they want a system designed to support everyday use instead of occasional trips.
The main appeal is straightforward: this unit is built around high flow, temperature control, and RV-friendly convenience.
The listing claims 66,000 BTU output, up to 3.6 GPM, altitude operation up to 9,800 feet, a winter/summer burner mode, and a mixing tank intended to smooth temperature swings.
That combination points to a product designed for practical use in real travel conditions, not just headline specs.
It is not the most compact or simplest option, and buyers should check cutout and door compatibility carefully.
But for the right RV, this is a strong candidate if you want more usable hot water, fewer waiting issues, and an install bundle that reduces the number of extra parts you need to source separately.

Key Features and Specifications of InstaShower 9 Pro
The FOGATTI InstaShower 9 Pro is a 3rd-generation RV tankless water heater with a clear focus on higher output and more predictable hot water delivery.
The listed 66,000 BTU output and up to 3.6 GPM flow are the headline figures, but the more interesting part is how the unit tries to make that output feel usable in everyday RV life.
Here are the most useful details from the listing:
| Feature | What the listing says |
|---|---|
| Heat output | 66,000 BTU |
| Flow rate | Up to 3.6 GPM |
| Temperature control | Within +/- 1 degree F |
| Altitude capability | Up to 9,800 feet |
| Door size | 15×15 inches |
| Trim ring | 17.64×17.64 inches |
| Opening compatibility | 13×13 opening |
| Included accessories | 150 PSI pressure relief valve, remote controller, door, trim ring |
| Safety features | CSA certification, forced exhaust fan, automatic gas shutoff, anti-freeze protection |
The built-in mixing tank is the feature that separates this model from many generic tankless RV heaters.
In practice, that is meant to help blunt the hot-cold swings that can happen when demand changes quickly.
For families or couples who use the shower and sink in succession, that matters more than raw GPM alone.
The listing also says the burner adapts by season: two rows of flames in summer to reduce overheating and all five rows in winter to maintain warmth.
That is a practical detail, because RV users do not live in one climate.
A unit that can behave differently across weather conditions is easier to live with than one that only looks good on paper.
The package is fairly complete.
FOGATTI includes the pressure relief valve, door, trim ring, and remote controller, which lowers the number of separate purchases many buyers would otherwise need.
The included filter screen is another small but useful touch, especially for travel conditions where dust and sand are common.
Pros and Cons of InstaShower 9 Pro
Pros
- Strong listed output for an RV unit, with 66,000 BTU and up to 3.6 GPM.
- Built-in mixing tank should help smooth temperature changes.
- Temperature control is listed as precise, which is valuable for showers.
- Includes the relief valve, door, trim ring, and remote controller.
- CSA certification and multiple safety protections improve confidence.
- Altitude support to 9,800 feet broadens where it can be used.
Cons
- Retrofit size still needs careful checking before purchase.
- The feature set is more advanced than what casual weekend campers may need.
- Buyers focused on the smallest, simplest setup may find the package overbuilt.
- Performance claims are strong, but the article is based on listing evidence, not hands-on testing.
Who Should Buy InstaShower 9 Pro?
Buy the FOGATTI InstaShower 9 Pro RV Tankless Water Heater if you want a more serious hot water system for frequent RV use.
It looks especially relevant for people who shower daily on the road, travel with more than one person, or simply dislike the lag and recovery limitations of a small tank heater.
It also suits buyers who value a more complete package.
The included remote controller, trim ring, door, and pressure relief valve make this a more turnkey option than bare-bones alternatives, which can be helpful if you want fewer missing parts during installation.
This is also a sensible choice if you travel in variable conditions.
The altitude support, forced exhaust fan, anti-freeze protection, and seasonal burner behavior all point to a design that is supposed to hold up across a wider range of RV use cases.
Skip it if your RV use is light and you rarely push the water system hard.
If you only take short trips, have very modest hot water needs, or prefer the easiest possible retrofit, the extra capability here may not be worth the complexity.
Temperature Stability and RV Fit
Why the mixing tank matters
The built-in mixing tank is the most interesting part of the design.
On an RV tankless heater, the real problem is often not simply making hot water, but keeping it from swinging when flow changes.
FOGATTI appears to address that directly, which is why this model stands out for people who care about shower comfort.
How the seasonal burner design helps
The summer and winter flame configuration is a good sign that the unit is meant to handle changing ambient conditions.
You are not left hoping one static burner pattern works everywhere.
That kind of adaptability is useful in a product that may see very different climates over the course of a year.
What to check before ordering
The practical buying question is fit.
The listing says the unit fits a 13×13 opening and uses a 15×15 door, while some replacements may require an 18×18 retrofit for older 10-gallon setups.
That means the part can be attractive on paper and still be wrong for a specific RV cutout.
Measure first.
Why the remote controller is more useful than it sounds
The included remote is not just a convenience extra.
In an RV, not needing to stand at the heater or keep reopening access just to adjust operation is a genuine quality-of-life improvement.
It supports the product’s broader goal: making hot water feel less improvised.
Alternatives to InstaShower 9 Pro
If you want a different RV tankless path, compare it with Girard RV tankless water heaters for a common RV-focused alternative, Furrion tankless water heaters for another established RV line, and Suburban RV water heaters if you are considering a more traditional tank-based approach instead.
The right alternative depends on what you value most.
If you want a straightforward tankless RV setup, Girard and Furrion are the nearest comparison points.
If your priority is simplicity and you do not need the instant-hot-water behavior, Suburban remains relevant because it represents the conventional tank route.
Is InstaShower 9 Pro Worth It?
The FOGATTI InstaShower 9 Pro RV Tankless Water Heater is worth considering if you want a high-output RV hot water solution with real attention paid to stability, safety, and install convenience.
Its strongest case is for frequent RV users who care about comfort and who have verified the fit for their coach.
If your setup can accommodate it, this is a serious, well-featured RV water heater rather than a stripped-down replacement.
If you only need occasional hot water on lighter trips, you may be better off choosing a simpler or less specialized option.
