Who it fits
Good fit for
This unit suits RV owners who want endless hot water without waiting for a tank to reheat. It is ideal for travelers who camp at high altitudes, as the staged combustion mode prevents overheating and saves propane. The compact 15-inch square design fits standard 6-gallon tank openings, making installation straightforward. You also benefit from the included remote controller and pressure relief valve, which simplify setup and enhance safety during your trips.
Who should skip it
Skip this model if you need a gas-fired heater for a stationary home. It is designed specifically for 12V DC RV electrical systems. If your RV uses a 10-gallon tank, you will need to retrofit an 18 x 18 inch door, as this unit fits only 13 x 13 inch openings. It also requires propane fuel, so it is not suitable for electric-only setups or those without a propane supply.
Verdict: The Fogatti InstaShower 8 Plus offers continuous hot water and high-altitude performance in a compact form. It is a solid choice for RVers replacing standard 6-gallon tank heaters.
FOGATTI InstaShower 8 Plus Key Specs
55,000 BTU
This heating capacity determines how quickly the unit raises water temperature. A 55,000 BTU input allows for robust performance in cold conditions. You get consistent heat output even when inlet water is chilly. This power level supports the stated flow rate without significant temperature drops. It ensures reliable hot water delivery during longer showers in your RV.
2.9 GPM
Gallons per minute measures the maximum volume of hot water the heater can produce. A 2.9 GPM flow rate is sufficient for a single shower or sink use. It prevents the sudden cold shock that occurs when tank heaters run dry. You enjoy continuous hot water for one person. This rate is ideal for RVs where water conservation and steady supply matter.
12V DC
This voltage rating indicates the electrical power source required for the unit's operation. A 12V DC connection allows the heater to run directly from your RV battery. You do not need a standard household outlet or inverter to power the controls and fan. This makes it compatible with standard RV electrical systems for easy installation and mobility.
Propane
Propane is the fuel source used to generate heat. This fuel type is common in RVs and off-grid setups. You can refuel at most gas stations or propane exchange locations. It provides high energy density for efficient heating. Using propane means you are not dependent on shore power or generators for hot water generation during travel.
15 x 15 x 15 inches
These dimensions describe the physical footprint of the unit. A cubic 15-inch size is compact and fits into standard RV water heater compartments. It replaces many 6-gallon tank models without major modifications. You save space in your RV's utility area. The small profile ensures it does not obstruct other storage or equipment in tight quarters.
Design and Build Overview
The unit measures 15 x 15 x 15 inches according to the listing. This cubic footprint allows it to replace standard 6-gallon tank water heaters in most RVs. The opening size is 13 x 13 inches, while the included door is 15 x 15 inches. You can swap it out for Suburban, Atwood, Girard, or Furrion models without major structural changes. If your previous heater was a 10-gallon tank, you will need to retrofit an 18 x 18-inch door. The compact design saves valuable storage space in tight camper compartments.
The device features a black finish and includes a built-in pressure relief valve. You do not need to purchase or install this safety component separately. A forced exhaust fan sits on top to ensure stable combustion. This layout helps prevent overheating and improves safety during operation. The unit also includes an intelligent remote controller with a 2-meter cable. You can adjust settings from a distance, which is useful in small bathrooms. The 12V DC power requirement means it runs directly off your RV’s battery system. This setup ensures you get hot water even when disconnected from shore power. The CSA certification indicates it meets specific safety standards for propane appliances. You get continuous hot water without waiting for a tank to refill. The design prioritizes reliability and ease of installation for mobile living.
Setup And Everyday Use Details
Installation involves replacing your existing tank unit. The listing states the opening size is 13 by 13 inches. The included door measures 15 by 15 inches. This fits standard 6-gallon tank spaces from brands like Suburban and Atwood. If you previously used a 10-gallon tank, you may need an 18 by 18-inch door. The unit includes a pressure relief valve, so you do not need to buy one separately. You also receive a remote controller. The cable is 2 meters long. This allows you to adjust settings without reaching the unit.
Daily use relies on propane fuel. The system runs on 12V DC power. You get up to 2.9 gallons per minute of hot water. This flow rate supports continuous showering. You will not run out of hot water after a few minutes. The unit lasts over 40 minutes of supply, compared to 5 to 8 minutes for small tanks. A high-altitude mode is available.

Before You Buy This Heater
Before you install this unit, verify your RV’s electrical system supports 12V DC power. The listing notes it replaces standard 6-gallon tanks from brands like Suburban and Atwood. Check your existing opening size, which is typically 13 by 13 inches. If you previously used a 10-gallon tank, you will need to retrofit an 18 by 18-inch door. The package includes a 15 by 15-inch door and a remote controller up to two meters long. You do not need to buy a separate pressure relief valve, as it is built into the unit. This propane heater offers continuous hot water, unlike tank models that run out after a few minutes. It is suitable for high altitudes up to 9,800 feet. Consider whether your RV’s propane supply can sustain 55,000 BTUs during extended use. This unit fits well if you prioritize endless hot water over stored reserves.
Check before you buy

- Measure your existing water heater opening size.
