Warm water without electricity or gas
Warm shower water without the long wait: reaches the perfect temperature in just 5 minutes.
Outdoor shower with wood-fired instantaneous water heater
Functional design meets solid construction, for year-round outdoor use.
High-quality
stainless steel
Crafted from 2 mm V2A stainless steel, the outdoor shower is designed for permanent outdoor use. The weather-resistant material ensures long-term value retention without compromising aesthetics or functionality.
Fresh water
instead of a water tank
The outdoor shower operates without a stagnant storage tank: About 7 liters of water are in constant flow and are heated directly during the heating process. This prevents the buildup of germs and ensures absolutely fresh shower water with every use.
Winter-proof
through draining
The shower remains outdoors all year round. The red lever drains all internal pipes in an instant. This saves you the tedious task of dismantling it in autumn and enables operation even in cold winter months.
Austrian
craftsmanship
Every outdoor shower is created as a unique piece in our Austrian workshop. We manufacture exclusively using sustainable hydropower and, through our regional roots, preserve an honest craft that blends harmoniously into your garden.
Wood-fired outdoor shower
Patented
heating system
Completely without electricity or gas. Efficient combustion provides warm shower water in just 5 minutes, a well-thought-out solution that works at any time, even on cold days, simply by lighting a fire with dry wood.
Quadruple
heat exchanger
Maximum energy efficiency thanks to the water-jacketed firebox. The heat from the fire is transferred directly to the system water; this achieves high efficiency and is technically implemented with precision down to the smallest detail.
Dual
system safety
Two independent mechanisms protect the system: A thermal relief valve prevents overheating, while the integrated pressure relief valve protects against excessively high line pressure. This ensures reliable and safe operation.
Integrated
heat shield
A custom-fit heat shield made of aluminum completely encloses the flue pipe. It prevents direct contact with hot surfaces and creates the conditions for safe use of the shower anywhere in the garden.
Setup & Use
Precise
mixing valve
The water temperature can be regulated just like an indoor shower. The heated water is mixed directly with cold water, allowing you to precisely and easily set your preferred temperature for outdoor showering.
Uncomplicated
water supply
The shower only requires a constant water pressure of 2-4 bar. The connection via a standard click system and a conventional garden hose simplifies handling and speeds up the initial setup for outdoor use.
Stable floor
mounting
As standard, the outdoor shower is delivered with a base for fixed installation on a solid surface. Alternatively, the optional slab stand allows for tool-free setup. This is weighed down with paving slabs (40cm x 40cm) and allows for variable placement anywhere.
Compact
delivery
A solid wooden crate reliably protects the outdoor shower during transport. Assembly is achieved by simply screwing three modules together: base, instantaneous water heater, and flue pipe. The entire system is fully ready for use in no time at all.
Always included
All necessary parts for assembly are included in the delivery. The shower is ready for use immediately after assembly.

Questions about the Feuerwasser Outdoor Shower
How much wood is needed per shower with the outdoor shower?
The outdoor shower works as a highly efficient wood-fired instantaneous water heater. A single filling of the firebox is enough for a warm shower lasting about 5 to 10 minutes. For this, you need approximately 1-2 large logs, chopped into small pieces.
Important: Use thin wood (approx. 1–3 cm in diameter). Since the water is heated by the flames, a lively fire is essential, rather than glowing embers.
Duration: Depending on the initial water temperature, flow rate, and desired heat, you can shower with a single filling without needing to add more wood. For longer showers or multiple people, simply add small amounts of wood to the fire continuously.
How quickly can I take a warm shower?
After just 5 minutes. A strong fire with high flames is important. Since the outdoor shower works as a wood-fired instantaneous water heater, the water is heated directly by the flames and is ready to use immediately after this short heat-up time.
How long can I shower with the outdoor shower?
Cold water: Once the water connection is set up, you can shower for an unlimited time.
Warm water: After a short heat-up time of about 5 minutes, the outdoor shower provides continuous warm water, as long as you regularly add small pieces of wood. The continuous flow system allows multiple people to take a warm shower one after the other without interruption.
Can the Feuerwasser outdoor shower overheat?
No. Our patented instantaneous water heater is equipped with multiple safety features and protected against thermal overheating. Should the water inside the firebox jacket reach 99 °C, a thermal relief valve opens. The hot water is then discharged downwards through the base in a controlled manner, while cold water is automatically fed in from the water supply.
How does the wood-fired outdoor shower work?
The outdoor shower is simply supplied with water via a garden hose connected to the base. First, the shower is completely filled with water by opening the showerhead until no more air escapes. Next, a strong fire is built in the firebox, which heats the water surrounding it. After a few minutes, the desired temperature can be set using the mixing valve, and you can enjoy a warm shower for as long as the fire is burning. After showering, the garden hose is disconnected and the drain valve is opened so that the water can drain completely from the shower.
Can I use the outdoor shower in winter? And if so, how?
Yes, you can use the Feuerwasser outdoor shower in winter just as usual.
It is important that you follow these 3 steps after using the shower in freezing temperatures:
Open the red drain valve as usual after showering.
Remove the hand shower and hose from the valve and ensure that the valve is open.
Turn the mixing valve once to cold and once to hot so that any remaining drops of water can escape.
This ensures all parts of the shower are completely drained of water and winter-proof.
How do I maintain the outdoor shower with the wood-fired water heater?
The Feuerwasser outdoor shower is very low-maintenance and easy to care for. Regularly remove the ashes from the stove. If a valve or seal ever needs to be replaced, we are happy to help.
How is the outdoor shower secured to the ground?
Every Feuerwasser outdoor shower comes with a mounting base for concrete surfaces. This base is anchored to the ground using three screws; the foot of the shower is then placed over it and secured from the side with screws.
Alternatively, you can purchase the slab stand in our shop, which allows you to set up the outdoor shower flexibly anywhere. Four standard paving slabs (40x40x4 cm) are sufficient to ensure a secure hold.
Does the surface of the firebox get hot?
During regular operation, the surface of the firebox remains safe to touch, as it is continuously cooled by the flowing water. Only in exceptional cases – when a fire is burning while no water is flowing or the water supply has been turned off – can the surface temperature reach up to 99 °C.
What should I keep in mind regarding the sequence of turning on the water and lighting the fire?
Only light the fire once the water supply is established, and leave the water in the system as long as there is residual heat to prevent “dry heating”.
