Have you noticed a musty smell in your bathroom, loose shower tiles, or a water stain appearing on the ceiling below your shower? You might think it is a minor plumbing issue, but sometimes the problem starts underneath the shower floor.
A leaking shower pan can allow water to escape beneath the tiles and reach surrounding floors, walls, or ceilings. The frustrating part is that your shower may look perfectly normal while moisture is slowly causing damage out of sight.
Great American Plumbing & Drain Cleaning, Inc. provides professional shower pan testing in Broward and Palm Beach counties to help homeowners, condo owners, landlords, and property managers investigate suspected shower leaks.
Before spending money on repeated grout repairs or considering an expensive bathroom renovation, it is worth finding out whether the shower pan is actually leaking.
Think of the shower pan as the waterproof base beneath your shower floor. Its job is to keep water contained and direct it toward the drain rather than allowing it to seep into the surrounding structure.
A shower pan test checks whether this assembly is holding water properly.
During a typical test, a plumber seals the shower drain, introduces water to an appropriate level, and monitors the water level over a set period. If the level drops unexpectedly, it may indicate that water is escaping from the tested assembly.
The results help determine whether the shower pan may be contributing to the leak. Depending on the bathroom’s construction and the symptoms, additional investigation may be needed to identify the exact source.
The goal is simple-: understand what is happening before recommending repairs.
Not every shower pan leak starts with an obvious puddle. Sometimes the first signs appear in another part of the bathroom or even in the room below.
Wet baseboards or swelling trim near the bathroom
Water leaking outside the shower or into adjacent rooms
Musty odors, mildew, or recurring mold around the shower
Loose tiles, cracked grout, or “spongy” floors
Water stains on the ceiling below the shower
A persistent leak that only happens when someone showers (not when the sink runs)
If you are thinking “that sounds like my house,” do not wait. Water damage gets pricey fast.
A shower is used almost every day, so even a small leak can become a concern when water repeatedly reaches areas that are not designed to stay wet.Depending on the location and severity of the leak, ongoing moisture may contribute to-:
Rotting subfloors and damaged framing
Mold growth behind tile and drywall
Ceiling collapse risk in multi-story homes and condos
Insurance headaches and long remediation timelines
A test is a small step that can prevent a giant mess.
Here is how your friendly neighborhood plumber handles it:
Visual inspection
We begin by examining accessible areas of the shower, including the tiles, grout, corners, curb, drain area, and visible plumbing connections. We also look for nearby signs of moisture, such as staining, dampness, or changes to surrounding surfaces.
Timed monitoring
The shower pan is prepared for testing, and the water level is monitored over an appropriate period. If the level drops unexpectedly, it may indicate that water is escaping from the tested assembly. The results need to be considered alongside the shower's construction and testing conditions.
Next-step diagnosis (if needed)
If the initial test suggests a possible leak, we consider where the problem may be coming from. This may involve looking more closely at the drain connection, waterproofing system, or other accessible parts of the shower assembly.
Drain seal and controlled fill
The shower drain is sealed, and the shower base is filled to an appropriate testing level. The water is then monitored according to the testing requirements. This controlled process helps evaluate whether the shower pan is holding water as expected.
Clear recommendations
Once testing is complete, we explain the findings in straightforward language. Depending on the results, the next step may involve a targeted repair, additional investigation, drain work, or shower pan replacement. We want you to understand the available options rather than feel pressured into unnecessary work.
Most homeowners want to know how long they will need to keep the bathroom available for testing. The initial onsite work typically takes around 60 to 90 minutes, although the water-monitoring period may require additional time. A slow leak or a shower with difficult access may require a longer testing window. We can explain the expected process when you schedule your appointment so you know what to plan for.
There is not always one obvious reason why a shower pan starts leaking. Several parts of the shower assembly can contribute to the problem.
Common possibilities include-:
Failed shower pan liner or waterproofing membrane
Cracked grout or loose tile allowing water into the substrate
Failed drain flange or drain connection
Improper slope or standing water at the curb
Movement or settling that breaks waterproofing seams
Poorly sealed corners, curb, or bench areas
A shower can look “fine” and still leak underneath. That is why testing matters.
When homeowners notice water around a shower, grout is often the first thing they suspect. It makes sense because cracked or missing grout is easy to see. However, grout and tile are not substitutes for a properly installed waterproofing system. A shower can have good-looking grout and still have a problem with its liner, waterproofing membrane, or drain connection. Simply replacing the grout may not resolve a leak coming from underneath the shower floor. Before spending money on repeated surface repairs, consider whether a shower pan test can help establish if the pan is holding water properly.

It is natural to want to know the price before scheduling a service. The cost of shower pan testing depends on several factors, including the type of shower, access to the drain and surrounding areas, the condition of the shower, and whether additional diagnostic work is needed. A straightforward test may involve less work than a situation where the shower has difficult access or signs of a more complicated leak. When contacting us, let us know your location, the type of shower you have, and what symptoms you have noticed. We can discuss the testing process and provide information about pricing before scheduling.

Water stains on the ceiling below the bathroom, damp flooring outside the shower, musty odors, loose tiles, and recurring moisture can all be warning signs. A shower pan test can help determine whether the pan assembly is holding water.
Yes. A leak can come from the shower pan liner, waterproofing membrane, drain connection, or another part of the shower assembly rather than the water supply pipes.
No. Grout fills the spaces between tiles, but it does not replace the waterproofing system behind the shower surface. Regrouting alone may not resolve a shower pan leak.
The initial onsite work typically takes around 60 to 90 minutes, although the water-monitoring period may require additional time. The exact duration depends on the shower and testing conditions.
You may need to avoid using the shower for a period before and during testing. Our team can explain any preparation requirements when scheduling your appointment.
An initial shower pan test is generally performed without removing tiles. If the results indicate a problem, additional investigation or repair work may be necessary, and that could involve opening part of the shower assembly.
A failed test suggests that the tested assembly may not be holding water properly. We explain the findings and discuss possible next steps, which may include additional diagnosis, a targeted repair, or shower pan replacement.
Yes. Shower pan testing can be useful for condo owners and property managers investigating suspected bathroom leaks or water complaints from neighboring units. Access and building requirements may need to be coordinated before testing.
