Wash a duvet in Karlsruhe: the large washing machine of 18 kg
To wash a duvet in Karlsruhe, use the large washing machine of 18 kg at the laundromat Karlsruhe-Oststadt: €13.50, with the Discount card from €10.20. Afterwards you dry it in a 20 kg dryer (€1.50 per 10 minutes).

Why a home machine often gives up on duvets
Ordinary household machines usually hold 6 to 8 kg. A wet winter duvet gets heavy and no longer floats freely, the drum is loaded on one side and the water does not reach everywhere. The large washing machine of 18 kg at the laundromat Karlsruhe-Oststadt has enough space for the filling to be rinsed through loosely.
Which duvets fit
- Synthetic and microfibre: Easy to machine wash and quite quick to dry.
- All-season and winter duvets: These belong in the large machine.
- Pillows and summer duvets: Fine in the 8 kg machine too, as long as they are light.
- Down and feathers: Also possible, but they need more care, see our own guide.
The care label always has the last word: if it says “do not wash”, leave it.
How it works, step by step
- Fold the duvet loosely and put it into the XXL drum.
- Add detergent, from the machine (€0.70) or your own.
- Pay, press the start button, and about 35 minutes later the duvet is done.
- Move it straight into a 20 kg dryer and dry it patiently until nothing feels damp.
What does it cost?
A duvet at €13.50 in the XXL machine plus 30 minutes in the dryer (€4.50) comes to €18.00. With the Discount card it is €13.50 (€10.20 plus €3.30). Got two duvets? They go through the XXL machine one after the other, because we have one of them. Meanwhile you can wash pillows and bed linen in an 8 kg machine. In the dryer each duvet gets a dryer of its own.
Making use of the waiting time
You do not have to wait next to the machine: from Ludwig-Wilhelm-Straße it is a few minutes on foot to Karl-Wilhelm-Platz. Just be back as soon as the machine has finished, so the next person can use it.
