You see circles in your ceiling under the bath. We at Ultrices Leak Detection focus on detecting ceiling leaks caused by baths without demolition.
We test drains, overflows, siphons, sealant edges, joints, pipes, and tile floors using thermography, smoke testing, dye, and acoustics. This allows us to limit water damage and mold and locate the source.
You receive a clear report for insurance, repair tips, and a fixed price. If you want proof and to know where the water comes from, read our 5/5 Google reviews via reviews about tracing ceiling leaks caused by bathtubs.

Detecting a ceiling leak caused by a bathtub in the house
Ceiling leakage caused by a bathtub is treacherous. You see wet spots or rings on your ceiling, but the source is often located higher up in the bathroom. At Ultrices Leak Detection, we track down ceiling leaks caused by bathtubs using professional detection equipment and smart methods, without any demolition or breaking work. We combine FLIR-quality thermography, acoustic detection, tracer gas, and dye analysis with structural insight into drainage systems, capillary action, hydrostatic pressure, and vapor diffusion. Our team is VCA VOL and NEN 3140 certified, works nationwide for private individuals and businesses, delivers an expert report within three days, and liaises quickly with insurers to ensure your claim is settled smoothly.

Causes of ceiling leakage due to bathtub
- Defective drain or siphon: loose compression fitting, hairline crack in PVC or PE bend, leaking siphon or overflow leaking below water level during bathing.
- Sealant joints and joints: outdated silicone sealant or cracks in tile joints allowing splashing water and capillary moisture to penetrate the floor.
- Overflow and bathtub rim: leaking overflow gasket, incorrect connection of drain plug, leaking bathtub rim due to sagging frame or incorrect installation.
- Pipes in the floor: leakage in hot and cold water pipes or couplings in the floor above the ceiling, often visible as hot or cold spots.
How we detect ceiling leaks caused by a bathtub
We use a phased protocol that uncovers the root cause and prevents unnecessary repairs.
- Intake and pattern recognition: we analyze damage patterns, moisture measurements, and usage moments such as filling and emptying the bath.
- Pressure and discharge testsWe isolate water pipes for pressure loss measurements and test the drain and overflow with a controlled water column and dye.
- Thermography and acoustics: using infrared images and a microphone, we detect heat profiles and flow noise from leaking water or pipe vibrations.
- Endoscopy and tracerWe inspect hollow spaces with a camera and track tracer gas through micro-leaks in the structure.
- Validation and reportWe verify the source and provide a clear expert report with photos, findings, and repair advice that insurers accept.
Leak detection process request
Diagnostic techniques without hacking or breaking
- Thermography: Infrared scans temperature fluctuations caused by warm bath water or cold infiltration in the event of a leak, ideal for pipes and wet areas.
- Trace gas: an inert gas mixture escapes through the smallest leak and is picked up by a detector, safely and with extreme precision.
- Dye inspection: fluorescent dye in bath and overflow shows whether the drain or sealant transitions are permeable.
- Acoustic correlationMicro-leaks produce a characteristic sound that we locate with sensitive sensors around the drain and floor.
- Hygrometry and salt testMoisture meters and chloride measurements distinguish fresh tap water from grey wastewater, useful for source determination.
Signs and risks associated with ceiling leakage caused by a bathtub
- Circles and discoloration: Yellow or brown edges indicate prolonged penetration through sealant joints or the overflow, often around ceiling fixtures.
- Bulging plasterwork: plasterboards lose strength due to repeated swelling and drying, with a risk of sagging and mold growth.
- Mold and odor: Black deposits and a musty odor indicate chronic moisture exposure and insufficient drying within the structure.
- Electrical riskWater in light fixtures and junction boxes can cause malfunctions; therefore, we work safely and in a controlled manner in accordance with NEN 3140.
Practical examples
- Overflow that only leaks when filling up: during a test with dye, we immediately saw leakage around the overflow gasket, resolved with a new seal and inspection of the fastening.
- Drain bend with hairline crackThermography showed a warm track under the bath during draining, followed by tracer gas that indicated the exact crack position in the PVC bend.
- Sealant edge failure: splashing water ran through an open sealant joint behind the tile strip into the concrete floor, visible as a cold spot with IR and as an elevated moisture level in the ceiling.
- Pipe connection in upper floor: pressure loss on the hot water unit and acoustic peak around the bath thermostat, repaired by replacing a compression fitting.

Frequently asked questions
How do you recognize that your ceiling leak is really caused by the bathtub and not by rain or another pipe?
Pay attention to signs that coincide with the use of your bath. If you see droplets or brown rings on the ceiling shortly after filling or draining the bath, hear dripping noises at the drain, or smell a sewer odor, this often indicates a problem with the siphon, overflow, or drain. If the ceiling remains dry during rain showers, a roof problem is less likely.
Typical causes include a leaking siphon or PVC drain pipe, a loose overflow, water running along worn silicone sealant at the rim of the bath, porous grouting, or failing waterproofing membrane. Immediately take the bath out of use, turn off the water if necessary, and document the damage with photos to ensure your claim proceeds smoothly.
How do you trace a ceiling leak caused by the bathtub without hacking and breaking?
We combine non-destructive testing with a smart sequence. We start with a structural inspection and moisture measurements using Trotec equipment, take a thermal image with a FLIR camera to visualize cold moisture traces, and perform dye tests with UV visible contrast to trace leaks along the tub rim and overflow. Where necessary, we use endoscopy to inspect under the tub or through an existing access hatch.
If a drain issue is suspected, we perform a controlled water column and pressure test on the siphon and drain line to quickly locate micro-leaks in PP or PVC connections. Everything is done cleanly and precisely, certified according to VCA VOL and NEN 3140. To learn more about inspections without demolition work, view our approach without heels.
How much does it cost to locate a ceiling leak caused by the bathtub, and is leak detection covered by your buildings insurance?
After a brief intake, we provide a fixed price, and you will receive a free quote within 24 hours. The investigation itself is compact and targeted, without unnecessary work. Within three working days, you will receive a comprehensive expert report including photos, measurements, and clear repair recommendations that a contractor can start working on immediately.
Leak detection for water damage to ceilings is often covered by buildings insurance, sometimes with an excess. We work with insurers daily, provide a report that meets acceptance requirements, and help you with a smooth claims settlement. Read how it works and what is included in the report via bathroom leak report for insurance.
What should you do immediately in case of a wet ceiling under the bathroom, and how quickly will you be on site?
Immediately take the bath out of use and shut off the water supply if you see an active leak. Place a bucket near drips, mark new damp spots with a pencil, and take photos or video for your insurance. If there is water around spotlights or electrical wiring, switch off that circuit in the fuse box and wait for a safe inspection.
