First, look at your toilet (2 minutes)
Everything depends on one small tap. Look behind or under the toilet for a small valve on the wall with a thin pipe going up to the cistern. That is the Eckventil (angle valve).
- You can see the cistern and the Eckventil (old-style toilet with the tank on top or low on the wall): perfect. Option 1 or 2 works.
- Toilet hangs on the wall, cistern is hidden (only a flush plate on the wall): the valve is behind that plate. Adding a jet spray here is a job for a plumber. Go to option 3.
Also check if there is a normal tap (washbasin) close to the toilet — some kits connect there instead.
Option 1: Handheld jet spray with T-piece
This is the one most of us know from home. A small T-piece goes on the Eckventil. One side keeps filling the cistern, the other side goes to the spray hose.
- No drilling: the T-piece screws on by hand and a spanner. Hang the spray on an adhesive hook or a clamp holder.
- Check the thread size on your valve before buying. Most German toilets use 3/8 inch, but not all.
- Choose a kit with its own small shut-off tap on the T-piece. This matters — read the warning below.
Option 2: Bidet seat attachment
A thin plastic plate that sits under your toilet seat, with a nozzle and a small knob on the side. It also connects to the Eckventil. No electricity needed for the simple ones.
Good if you do not want a hose hanging on the wall, or if kids find the handheld one hard to aim. The seat has to fit your toilet shape, so measure first.
Option 3: No fitting at all
For a hidden cistern, a very short stay, or a landlord who says no:
- A lota or a simple jug — works everywhere and costs almost nothing.
- A portable bidet bottle (squeeze bottle with a long nozzle). Also great for travel, trains and offices.
How to fit option 1 in a rented flat
- Turn the Eckventil fully closed (clockwise). Flush once so the cistern is empty.
- Put a towel down. Unscrew the pipe from the valve, screw on the T-piece, then the pipe back on the top and the hose on the side.
- Use the rubber rings from the kit. Hand-tight plus a small turn with a spanner. Too tight can crack the thread.
- Open the valve slowly and check every joint with a dry tissue for five minutes.
- Keep the original parts in a bag. When you move out, put everything back. The landlord sees the bathroom exactly as it was.
The one rule: close the small tap after every use. If you leave it open, the hose stays under full water pressure all day and all night. Cheap hoses can burst — often at night or when you are on holiday. That can flood your flat and the neighbour below. Close it after use, and the hose is empty and safe.
If you are not sure about any of this, ask a friend who has done it once, or pay a plumber for thirty minutes. Much cheaper than water damage.
Water temperature
In most German flats the toilet only has cold water. In summer that is fine. In January it is a shock. Some kits have a mixer that connects to the washbasin's hot and cold — but that needs a sink right next to the toilet and more work. Most people just get used to it.

Quick answers
Do German toilets have a jet spray?
Almost never. You have to add one yourself or use a portable option.
Can I fit a jet spray in a rented flat?
Usually yes, if it needs no drilling and you can remove it when you move out. Keep the original parts and put everything back at the end.
My toilet cistern is hidden in the wall. What can I use?
The valve is behind the flush plate, so fitting a spray is a plumber job. A portable bidet bottle or a lota is the easy option.
Why should I close the tap after using the spray?
Otherwise the hose stays under full water pressure and can burst, which can cause serious water damage.
Thirty minutes of work, and your bathroom finally feels like home. Just remember that little tap — close it every time.
