Bathroom drain unblocking in Belgium
The basin empties slowly, water stands in the shower tray, and the toilet struggles to flush away: when several fittings in the same bathroom fail together, it is almost never a coincidence. The problem rarely lies in each point separately, it sits in the waste pipe they share. We treat the bathroom as one system: we locate the shared cause and restore the flow on all your fittings.

Our method
A whole-room diagnosis before any clearing
Before acting, we work out where the blockage really is: in one particular trap or on the shared waste pipe. That diagnosis determines the right technique, not the other way round.
- 01
Listening and cross-testing
We run each fitting and watch how they react to one another. Those cross-reactions reveal whether the blockage is local or shared.
- 02
Locating the blockage
We establish whether the obstruction sits in one isolated trap or further along, on the shared collector that takes the basin, the shower and the toilet.
- 03
Targeted clearing
Depending on the cause: professional auger, pressurised water jetting or freeing the trap. We clear at the right place, without damaging tiling or fittings.
- 04
Testing every point
We check each fitting separately after the job, basin, shower and toilet, and tell you straight whether a follow-up check of the network would prevent a repeat.
Why treat the whole room
Treating the cause all the fittings share
When a bathroom backs up everywhere, the temptation is to go after the most visible point: the shower where water stands, or the toilet overflowing. But if the real cause sits on the shared waste pipe, clearing one fitting only moves the problem for a moment. The shared blockage stays put, and the backflow reappears at the next point. That vicious circle is exactly what our whole-room diagnosis sets out to break.
By pinpointing the obstruction on the collector, we restore the flow of the basin, the shower and the toilet in a single move. That is often quicker and cheaper than stringing together point-by-point visits, and above all far more durable. We also take the time to check the individual traps, because a shared blockage sometimes coexists with local fouling that is better dealt with at the same time.
That thoroughness changes nothing about our transparency on price. The cost depends on how deep the blockage sits and how many fittings are affected. Call us for a straight answer, evenings and weekends included.
The bathroom as one connected network
When several fittings fail, the cause is shared
In a bathroom, all the fittings are connected to each other. The basin, the shower or bath and the toilet each have their own trap, but their waste pipes eventually meet in a shared collector before heading off to the sewer. That shared architecture is why a problem at one point can quickly be felt at the others. Understanding that network is already half the diagnosis.
As long as only one fitting drains badly, the cause is usually local and harmless: hair and soap built up in the shower trap, limescale narrowing the basin's pipe. But when the basin empties slowly, water rises in the shower just as you flush, and the toilet hesitates to clear, the meaning changes entirely. That is the sign the obstruction sits downstream, on the stretch all the fittings use together.
Treating each point one after another then amounts to easing symptoms without touching the cause: you relieve one trap for a moment, but the shared blockage stays put and everything backs up again a few days later. The right approach is to establish first whether the blockage is local or shared, then clear the network at the right place so the whole room drains normally again.
Warning signs
The signs of a cause affecting the whole bathroom
Any one of these symptoms may be local, but several at once point to a shared blockage downstream. Better to have the whole room diagnosed.
- The basin and the shower drain slowly, or not at all, at the same time.
- Water rises in the shower or the tray when you flush the toilet.
- The basin gurgles or bubbles while the shower is running.
- A drain smell comes from several points in the room at once.
- The bathroom floor gets covered in water after every use.
- The level takes longer and longer to go down in every fitting.
Until we arrive
What to do while you wait for us
A few simple steps limit the damage and make the diagnosis easier. Most important: do not make an already shared blockage worse.
- 01
Stop using the room
Stop using the affected basin, shower and toilet: every extra use pushes more water into a network that is already blocked.
- 02
No chemical drain cleaner
Poured into a network that no longer drains, the product just sits there, damages the pipework and complicates our job without dissolving the blockage.
- 03
Mop up the standing water
Remove the water left in the shower tray or on the floor to avoid any overflow while you wait.
- 04
Clear access to the traps
Free the space around the basin, the shower and the toilet so the technician can test and reach each point quickly.
What the jobs actually look like
Every bathroom has its own story
A family bathroom mostly accumulates hair, soap and limescale residue that settles slowly in the traps, then migrates towards the shared pipe. In an older property, the fall of the waste pipes or the diameter of the runs can encourage deposits to catch and make shared blockages more frequent. We adapt our approach to the room's actual configuration rather than applying a single recipe.
Our priority stays the same in every case: restore reliable drainage across all the fittings and leave you a fully usable bathroom. If we find that a more thorough check of the network would help prevent repeats, we say so clearly and you then decide with the facts in hand, under no pressure at all.
Transparent pricing
What determines the price
Our call-outs start from €63.60 incl. VAT (6 % for homes over 10 years old, otherwise 21 %).
The price of unblocking a bathroom drain depends on the fixture involved (basin, bath or shower), where the blockage sits and the method needed to clear it.
Benefits
- Whole-room diagnosis before any clearing
- Shared cause treated, not each symptom
- One visit for basin, shower and toilet
- Fittings and tiling protected
- Every point tested before we leave
- Camera diagnosis if the cause stays unclear

+32 2 000 00 00How much does bathroom drain unblocking cost?
Our call-outs start from €63.60 incl. VAT (6 % for homes over 10 years old, otherwise 21 %). The price of unblocking a bathroom drain depends on the fixture involved (basin, bath or shower), where the blockage sits and the method needed to clear it.
My basin, shower and toilet are all backing up at once, what is happening?
When several fittings in the same bathroom block simultaneously, the problem rarely lies in each of them. It has to be looked for lower down, in the shared collector that takes the water from the basin, the shower and the toilet before sending it to the sewer. A blockage there backs up to every point at the same time. So we diagnose the whole room rather than one isolated fitting, to clear the real cause.
How do you tell a local trap from a shared cause?
By cross-testing: we run each fitting separately, then together, and watch the reactions. If running the shower makes the basin gurgle, or flushing brings water up in the tray, the obstruction is downstream. If only one point reacts, its trap is enough. Where needed, a camera inspection settles it definitively.
Can I unblock it myself when the whole bathroom is affected?
This is precisely the case where it is better not to. A plunger or a short auger does not reach the shared collector, and a chemical cleaner poured into a network that no longer drains just sits there, damages the pipework and makes the job more dangerous. Pulling out reachable hair around the wastes is still useful; beyond that, the diagnosis comes first.
How quickly can you come out to a blocked bathroom?
We treat these as a priority, because an unusable bathroom brings a whole home to a standstill. From the call we give you a realistic estimate of the arrival time.
Could the clearing damage my tiling or fittings?
No, as long as the tool is matched to the job. We choose the auger to fit the real diameter of each waste pipe, protect the trays, the wastes and the tiling, and set the pressure for small bores. We also avoid pointless dismantling: in most cases the network clears through the existing wastes.
When should you call a drain technician straight away?
Some signs mean the blockage is no longer local: waste water backing up into a shower, sink or toilet, several fixtures draining slowly at the same time, water rising from a yard gully, or a sewer smell that lingers despite ventilation. In those cases, avoid reaching for chemical drain cleaners again and again: they attack seals and pipework without reaching a blockage further down the run.
