What is a bathroom floor leak and why it matters
A bathroom floor leak is water that seeps away, whether visible or hidden, through the bathroom floor and damages building components. It often occurs under tiles in the cement screed or at pipe penetrations around the shower drain and drain. Due to capillary action and vapor diffusion, moisture seeps into the joints and underlying layers, which can lead to mold, peeling plaster, and even short circuits. At Ultrices Leak Detection, we track down every leak in the bathroom floor using professional detection equipment, without any demolition or breaking work, with a success rate of ninety-nine percent and a comprehensive expert report that you will receive within three days.
Signs and causes of damage in your bathroom floor
When a bathroom floor leak is occurring, you can see it through subtle and obvious signs. We link symptoms to the most common causes in materials such as PVC and PE drains, copper and PEX water pipes from brands like Wavin, Viega, Uponor, and Rehau, and finishing products such as sealing tape and waterproof membranes from, for example, Schluter Kerdi. Failures against NEN 1006 drinking water installations or NEN 3215 drains can also play a role.
- Wet joints or dark edges: persistent moisture around the shower drain or drain often indicates failing sealant joints or leaking connections
- Damp patches on the ceiling below: dripping or rings below indicates a leak in the bathroom floor or penetrations through the floor slab
- Loose tiles and hollow sound: due to osmosis and softened adhesive, tiling comes loose and the screed sounds different when tapped
- Moldy smell and white salt efflorescence: hygroscopic salts migrate and leave traces along skirting boards and edges
How we professionally locate your bathroom floor leak without any demolition work
We work in accordance with Kiwa-recognized protocols and use thermography with a FLIR infrared camera, acoustic microphones, endoscopy, smoke test, fluorescein dye test, and hydrogen- and nitrogen-based tracer gas. We combine this with data logging and pressure testing to isolate sources and rule out collateral damage. Our team is VCA VOL and NEN 3140 certified, operates nationwide—including emergency calls—for private and business clients, and liaises with insurers and repair shops.

Types of leaks in the bathroom floor with practical examples
The source varies depending on the situation. Through years of case studies, we recognize patterns and test them against measurement data.
- Sealant joint and edge sealing: missing or outdated silicone and incorrectly applied sealing tape cause track-in damage around the shower corner
- Drain and siphon: hairline crack in PVC pipe or leaking sleeves under the shower tray causes drip leakage that migrates via the screed
- Shower drain or sump: incorrect slope or leak in the gutter connection under the tile layer leads to seeping water
- Underfloor heating: micro-leak in a PEX or multilayer pipe circuit causes pressure loss and warm moisture patterns visible with thermography
We always test these types against installation requirements from, for example, NEN 1006 and NEN 3215, and check for KOMO-certified connection details where applicable.

Frequently asked questions
What are the causes of leaks in your bathroom floor and which signs should you take seriously?
Common causes include porous or cracked grout, worn silicone sealant along the shower tray or bath, a leaking collar at the shower drain or shower trap connection, a damaged waterproof membrane or sealing tape, defective drain pipes, leaking hot and cold water piping, and a leaking underfloor heating circuit. Incorrect slope can also push water under tiles. Signs include loose or hollow-sounding tiles, wet edges, mold, a musty odor, white efflorescence, warm spots, and damp patches on the ceiling below.
Stop showering, dry the surface, and turn off the main valve if water continues to run. Take photos for your insurance and call Ultrices Leak Detection.

How do you locate a leak in the bathroom floor without demolition?
We combine non-destructive testing with thermography to detect heat leaks and moisture patterns, ultrasound and acoustics to track micro-noises in pipes, fluorescein dye tests for drains, smoke tests for vents, and endoscopy through existing openings. Moisture measurements and pressure tests refine the diagnosis. Our VCA VOL and NEN 3140 certified specialists work with professional detection equipment for maximum accuracy.
You will receive a clear diagnosis with a photo report and measurement report, including repair advice in line with NEN 3215 for drains. The full expert report will be ready within 3 days.

I have damp patches on the ceiling under the bathroom; do I need to take immediate action?
Yes, do not wait. Water seeps further into your home via the screed and seams, posing a risk of mold, damage to wooden parts, loose plasterwork, and potential short circuits in recessed spotlights. Hot water accelerates damage and can permanently damage your floor finish or underlying spaces. If you also see scorching or discoloration around light fixtures, switch them off immediately.
Limit the use of the shower and bath, lay down towels, and leave windows slightly ajar. Call our emergency line; we are available 24 hours a day, 7 days a week, and in emergencies, we are often at your doorstep within 1 hour. Ultrices Leak Detection locates the leak without demolition and provides substantiated repair advice with a guarantee of coverage, indicative of which depends on the policy.
