A blocked toilet in a holiday rental or hotel room is an emergency that cannot wait for a plumber to arrive. The video above demonstrates the core technique, and this guide walks you through each step so you can clear most standard blockages using items already in the kitchen or bathroom. Whether you manage a villa in Corfu, an apartment in Athens, or a boutique hotel anywhere in Greece, these methods will get the fixture working again fast.
Why These Methods Work
Most toilet blockages sit within the first bend of the pan and consist of paper and organic waste rather than solid foreign objects. Hot water raises the temperature of the blockage and softens it, while dish soap acts as a lubricant that helps the mass slide through the trap. Together, the two create conditions in which gravity and a gentle flush can do the rest of the work without any specialist equipment.
The wire-hanger method is a physical fallback for cases where the blockage sits slightly deeper or is more compacted. A coat hanger reshaped into a hook gives you roughly 60 cm of reach and enough flexibility to break up or dislodge material that liquid alone cannot shift.
When to Call a Plumber Instead
If water is already overflowing, or if repeated attempts over 20 minutes produce no improvement, stop and call a licensed plumber. The same applies if you suspect a solid foreign object — a toy, a bottle cap, or anything rigid — has been flushed. Forcing water past a hard obstruction can push it further into the soil pipe and turn a minor job into a costly excavation.
In Greece, older properties often have narrower-bore pipework and lower-flush cisterns, which means blockages can recur. If a toilet blocks more than once a month, a professional camera inspection is worth arranging before the high season begins.
How to Unblock a Toilet Without a Plunger
- 1
Add dish soap to the bowl
Squeeze three to four tablespoons of washing-up liquid directly into the toilet bowl, aiming for the drain opening at the bottom. The soap sinks through the water and begins coating the blockage. Let it sit for five minutes before moving to the next step — the resting time matters because the lubricant needs to penetrate the mass rather than simply floating on top.
- 2
Pour in hot (not boiling) water
Fill a large pot or bucket with the hottest tap water available, or heat water to roughly 70–80 °C — hot enough to steam but not at a rolling boil. Boiling water can crack a ceramic pan, especially in older Greek properties where the enamel has aged. Pour the water in steadily from waist height; the height adds pressure and helps drive the soap deeper into the trap. Wait another five minutes.
- 3
Attempt a gentle flush
If the water level in the bowl has visibly dropped, the blockage has likely shifted enough to flush. Press the flush handle slowly and watch the drain. A successful result will see the water spiral out quickly and the bowl refill to its normal level. If the level rises again without draining, do not flush a second time — you risk an overflow. Move to step four instead.

Use a wire coat hanger if the blockage remains
Unwind a metal coat hanger and straighten it as much as possible, then bend one end into a small hook or loop to avoid scratching the porcelain. Wearing rubber gloves, insert the hooked end into the drain opening and work it gently in a circular motion to break up or hook the obstruction. Avoid jabbing forcefully. Once you feel resistance loosen, withdraw the hanger, then repeat the hot-water pour from step two.
- 5
Flush and clean the area thoroughly
Once the drain clears, flush the toilet two or three times to confirm the pipe is fully open and water is draining at normal speed. Discard the wire hanger safely, clean the outside of the bowl and the floor around the toilet with a disinfectant spray, and wash your hands thoroughly. For rental properties, note the incident in your maintenance log so you can spot any pattern of recurring blockages before they affect guests.

FAQ
- Is it safe to use boiling water in a toilet bowl?
- No. Boiling water (100 °C) can crack the ceramic bowl or damage the wax seal at the base of the toilet, creating a leak that is far more costly to fix than the original blockage. Use very hot tap water or water heated to around 70–80 °C, which is effective at softening blockages without putting stress on the porcelain.
- What if I do not have dish soap — can I use shampoo or hand wash instead?
- Yes. Any liquid soap product will work because the effect is purely mechanical lubrication rather than a specific chemical reaction. Shampoo, shower gel, and hand soap all contain surfactants that reduce friction and help the blockage slide through the trap. Use a similar quantity — three to four tablespoons — and allow the same five-minute resting time before adding hot water.
- How can I prevent toilet blockages in a holiday rental?
- Place a clearly visible sign in every bathroom reminding guests that only toilet paper should be flushed — no wet wipes, cotton pads, or paper towels, even if labelled flushable. Keep a plunger in every bathroom so minor blockages can be handled immediately. Before each changeover, run a slow flush while watching the drain speed; a sluggish drain is the earliest warning sign of a partial blockage forming.
