You can tell by a high water bill caused by a bathroom leak and a water meter that keeps running. You might spot damp spots or mold near the shower, toilet, or sealant. We can help.
We find hidden leaks in pipes and drains using thermography, acoustic tracer gas, and camera inspection. You will receive a clear leak detection report for repairs and your insurer.
This way you save water and prevent ceiling stains and extra costs. Read our Google reviews 5 out of 5 via experiences with high water bills due to bathroom leakage and call Ultrices leak detection.

High water bill explained by bathroom leak
A high water bill due to a bathroom leak is often caused by a hidden pipe leak or a silent flush in the toilet that keeps the water meter running continuously. In many homes compliant with NEN 1006, the drinking water installation is concealed behind tiling and the cement screed, meaning a micro-leak can remain invisible for weeks. Due to capillary action, water seeps into the grout and under the tile bed, while evaporation conceals traces on the surface. In hot water pipes, hydrostatic pressure accelerates loss, and a pinhole in copper or a crack in multilayer pipe can cost thousands of liters per month. We at Ultrices Leak Detection link this consumption to measurement data and pinpoint the source before the damage escalates.
Causes in the bathroom that drive up your bill
- Running toiletThe concealed cistern from, for example, Geberit or a similar brand can leak slowly due to a defective membrane or dirt under the float, causing liters per hour to disappear silently.
- Defective sealant and jointsDried-out silicone sealant or hollow joints allow spray runoff and splashing water to penetrate onto the cement screed, causing the water meter to sometimes run inexplicably longer after showering.
- Leaking mixer tap or shower tapA worn cartridge or a leaking compression fitting behind a finishing plate causes drip loss that leaks invisibly into the wall.
- Crack in water pipe: Copper pipe with pitting corrosion or a damaged PEX or multilayer pipe causes pressure loss and continuous consumption even when all taps are closed.
- Drain and siphon problems: A cracked shower tray drain or a poor seal around the siphon allows shower water to seep into the structure and accelerates moisture transport.
This is how we trace the bathroom leak without hacking or breaking.
We combine multiple techniques according to a fixed protocol so that you have clarity quickly and repair costs remain limited. Using professional detection equipment from FLIR and Trotec, among others, we locate the source with a 99 percent success rate.
- Data and meter analysisWe read the water meter with volume flow at rest and during pressure build-up, and determine whether there is structural night consumption or peak loss.
- Thermography and moisture mappingInfrared images show hot water pipes and thermal bridges, while a capacitive moisture meter makes the moisture gradient in walls and floor visible.
- Acoustic correlationUsing an electroacoustic microphone and correlator, we listen for leakage sounds in pipes in walls and floors and triangulate the exact location.
- Tracer gas or dyeIf necessary, we pump a safe hydrogen-nitrogen mixture through the pipeline or use fluorescein to visualize micro-leaks.
- Proof and final reportWe isolate subcircuits and perform a pressure test, after which you will receive our comprehensive expert report within three days, including photos and repair advice.

Signals and examples from practice
- Water meter keeps running: With all taps closed, the small red pointer of the dial gauge continues to turn, indicating hidden consumption in the water pipes.
- Heat glow in floorA warm streak in the tiled floor without underfloor heating often indicates a leaking hot water pipe behind the floor.
- Dark grout and mold: Local discoloration or soft grout around the shower corner indicates prolonged moisture exposure due to leakage.
- Lower water pressure: Pressure loss during simultaneous use is an indication of volume loss in a piping circuit.
- Suddenly high billA doubling of m³ consumption outside of holidays or renovations is almost always linked to a leak or a continuous flow.
This is how you limit costs and arrange reimbursement
We assist you with substantiated documentation for your building insurance and drinking water company. In the Netherlands, Vitens, Waternet, Dunea, Evides Waterbedrijf, Brabant Water, PWN, and WML, among others, handle reports of excessive consumption. Based on our measurement report, including a timeline of night consumption and leakage volume, a goodwill gesture for water loss is often applied, and the insurer reimburses consequential damage in accordance with policy conditions.
- Report the leak immediatelyRecord the meter reading at rest and after an overnight stay, and keep photos as evidence for the insurer and water company.
- Shut off subcircuits: Temporarily close the shut-off valves of the toilet or bathroom to minimize loss until our specialist arrives.
- Engage a professional investigatorOur VCA VOL and NEN 3140 certified leak detectors perform non-destructive testing with a guarantee of coverage.
- Submit claim completelyUse our expert report with measurement data, photos, and repair plan as the basis for billing and repair.

Frequently asked questions
Why is my water bill suddenly so high due to a bathroom leak, and which signs should you check for?
A suddenly high water bill often indicates a hidden pipe leak or a leaking shower connection. Look out for subtle signs such as a continuous soft flowing sound when stationary, damp spots on the ceiling or wall below the bathroom, a musty smell, warm tile surfaces in the case of hot water leaks, and mold growth around grout, sealant joints, and the shower drain collar. Even tiny drips along the siphon or toilet supply can cost hundreds of liters in a month.
In practice, we see that hairline cracks in tiles, porous grout, peeling waterproofing tape, and worn silicone sealant are common culprits. With professional detection, we measure abnormal moisture levels, trace heat patterns in hot water pipes, and check drains for micro-leaks without any demolition work, so that your consumption normalizes again.
How do you check for a hidden leak in the bathroom using the water meter?
Close all taps, turn off the dishwasher and washing machine, and note the water meter reading. Check if the counter or the trickle wheel continues to move. If it keeps turning while everything is closed, there is likely flow. Also check the main shut-off valve. Turn it off. If the counter stops then, the leak is behind your installation, often in or around the bathroom.
If in doubt, we perform a pressure test and flow measurement, and pinpoint the leak using thermography, acoustic measurement, and camera inspection of the shower drain and drain. If you want to see how that works, check out our page. Bathroom leak detection with camera or discover heat traces on Bathroom leak detection with thermography.
Are extra water costs and leak detection covered by insurance for a bathroom leak in the Netherlands?
Building insurance usually covers the costs of locating the leak and consequential damage resulting from an unexpected leak. Excess water consumption is not always reimbursed as standard; this depends on your policy and sometimes on the goodwill of the water company. Therefore, immediately record when you discovered the leak, take photos of the damage, and report it to your insurer quickly.
We help you with a clear expert report in accordance with insurance guidelines, including a measurement report and photos, within three days. Thanks to our collaboration with insurers and VCA VOL and NEN 3140 certification, you accelerate claims processing.
