What is bathroom leak detection and why it matters
Bathroom leak detection involves the targeted and non-invasive tracing of hidden water loss in your bathroom shower, bath, sink, toilet, and pipes. At Ultrices Leak Detection, we find the source without any demolition or breaking, using professional detection equipment and proven protocols in accordance with practical guidelines such as NEN 1006 for drinking water installations and ISSO knowledge dossiers. You prevent consequential damage to tiling, plaster blocks, concrete, and parquet, and you reduce the risk of mold and deterioration of grout and sealant joints. We work nationwide for private and business clients, with a success rate of 99 percent, a no-cure-no-pay policy, and an expert report that you can submit to your buildings or contents insurance. Our reviews score 5 out of 5, and you can reach us day and night at 085 2505 217 or info@Ultriceslekdetectie.nl
How we perform leak detection in the bathroom without demolition or breaking.
Our specialists combine sensors, geometry, and building physics to visualize water flows and moisture patterns. We utilize thermography with FLIR, moisture measurements with Tramex and Protimeter, smoke and dye tests, endoscopy with Ridgid, and hydrogen and nitrogen-based tracer gases with Trotec and Drager. This allows us to locate a leaking shower drain, defective sealant joint, cracked grout, a leaking concealed cistern such as the Geberit Duofix, or a press fitting from Wavin Tigris, Viega, Uponor, or Henco.

Signs of a bathroom leak that you must not ignore
- Moisture spots: yellow or brown edges on ceiling or wall, often next to the shower or under the bath
- Peeling mortar: hollow-sounding tiles, open joints and white efflorescence
- Moldy smell: musty smell in cabinets or near the concealed cistern and blackish-grey spots on sealant joints
- Unexplained water loss: your water meter keeps running or the water pressure drops without you drawing water
- Warm zones in floor: thermal pattern indicating a leak in underfloor heating or hot water pipes

Causes in the shower, bath, and sink that we often encounter
- Sealant joint and sealing tape: outdated silicone or damaged base sealant allows water to run under the tiling
- Drain and siphon: a leaking siphon or poorly glued PVC coupling in a shower drain or bath drain
- Concealed cistern and toilet: leakage at filling, flush bend or passage in the push plate compartment
- Hot and cold water pipes: hairline crack in PEX or copper, leaking compression fitting or failing press fitting
- Underfloor heating: point leak in a pipe or a defective manifold allowing moisture to migrate to the subfloor
A practical example from Rotterdam where we found an invisible leak at the shower drain in a walk-in shower with large tiles. Using dye in the grout and thermography, we detected flow under the tile, and repair costs were lower because no demolition work was necessary.
Technology and methods that make a difference
- Thermography: infrared images with FLIR show temperature gradients caused by flowing hot or cold water
- Humidity measurement and hygrometry: capacitive and resistance measurement with Tramex or Protimeter plus data logging
- Trace gas: hydrogen-nitrogen mixture migrating through micro-leaks followed with a sniffing probe
- Smoke and water proof: controlled simulation of splash and splash pressure at showers and sealant joints in accordance with test protocol
- Endoscopy: camera inspection of hollow spaces in shafts, under the bath and in false walls

Frequently asked questions
What is bathroom leak detection and what signs betray a hidden leak in your bathroom?
Typical signs include persistent damp patches on the wall or ceiling below the bathroom, mold edges, peeling grout or silicone sealant, a musty odor near the shower drain, and limescale deposits near the siphon, faucet, or toilet. A warm spot in the tiled floor may indicate a leaking hot water pipe or underfloor heating. A ticking or hissing sound after showering is also suspicious. We detect this non-destructively for both private individuals and businesses.
First, check your water meter yourself while all taps are closed. If you see the meter running, there is often a pipe leak. Also check the shower drain collar, cracks in tile grout, and the connection of your built-in shower faucet or thermostatic faucet. If it remains unexplained, we will provide targeted assistance with measuring equipment and a clear plan of action.
How does professional leak detection in the bathroom work without demolition?
We combine thermography with FLIR thermal cameras, an endoscopy camera behind the bath or shower wall, acoustic microphones on pipes, a smoke test on the drain, UV dye tests, and pressure tests with tracer gas on cold and hot water pipes. With accurate Trotec moisture measurements, we determine the leak path in tile floors, waterproofing tape, joints, or sealant. No demolition work required, but a 99 percent success rate and no cure no pay, completely risk-free.
Our team has over 15 years of experience, is VCA VOL and NEN 3140 certified, and works with insurers. After the detection, you will receive a detailed expert report including photos and a measurement report.

Emergency bathroom leak: what should you do now and how quickly can we be on site?
Immediately turn off the main valve, or close the hot and cold water shut-off valves in the bathroom. Turn off the power if there is moisture in the ceiling or on the power outlets, catch any drips, dry any visible water, and take photos of any damage. If you smell a sewer odor at the drain, do not use the shower for a while until we have taken measurements.
