Shower Installation in Greater Des Moines Area

Replacing Your Failing Shower Before It Destroys Your Bathroom

Are you feeling a sickening squish under your feet when you step in to wash up, fighting black mold that never stays gone, or staring at a growing brown water stain on the ceiling below? You cannot fix a cracked fiberglass pan, rotted subfloor, or failing wall plumbing with another tube of silicone caulk. True Comfort Heating, Cooling and Plumbing is ready to tear out the compromised materials and install a rock-solid, watertight shower in your home today.

Warning Signs Your Shower Needs a Complete Replacement

The Spongy, Flexing Shower Floor

When you shift your weight and the shower floor dips, groans, or feels noticeably soft, you are walking on borrowed time. This structural failure usually means the shower pan has cracked or the drain seal has failed, allowing water to slowly rot the wooden subfloor beneath your feet. If you ignore this flexing, the floor will eventually cave in entirely, turning a straightforward shower installation into a massive carpentry repair job.

Persistent Black Mold Behind the Caulk

If you are constantly battling aggressive black mold that returns just weeks after a heavy bleach scrubbing, your cleaning routine is not the problem. This rapid regrowth means moisture has breached the waterproof barrier and is actively trapped inside the wall cavity where air cannot reach it. Leaving this hidden moisture alone destroys your drywall, rots the wooden framing holding up the enclosure, and pumps dangerous mold spores directly into your indoor air.

Hairline Cracks in the Fiberglass or Acrylic

Small, spiderweb-like cracks in your tub or shower surround might look like minor cosmetic flaws, but they are actually active leak points. These fractures happen when the acrylic material becomes brittle with age or when the base was installed without a proper mortar bed for structural support. Once the surface cracks, water pushes through those tiny gaps every single time you shower, silently destroying the building materials behind the wall before you ever see a leak.

Water Stains on the Ceiling Below

A brown ring on the ceiling directly beneath a second-story bathroom is the classic red flag of a catastrophic shower failure. This happens when the drain assembly corrodes, the p-trap leaks, or the shower pan loses its watertight seal completely against the surrounding walls. Catching this early might save the ceiling drywall in the room below, but ignoring it will eventually result in water pouring through your living room ceiling during a morning shower.

Musty Odors Inside the Wall Cavity

Sometimes you smell the plumbing failure long before you ever see a single drop of water escaping the enclosure. A persistent, earthy odor that lingers in your bathroom even after a deep clean indicates standing water and active rot behind the shower walls. You cannot scrub away a smell that is literally baked into decaying wood and saturated drywall, meaning the entire assembly needs to be removed.

Common Causes of Shower Failure

The Void Under the Shower Pan

When we pull out a cracked fiberglass shower base, we almost often find empty space underneath the plastic pan. A proper installation requires setting the pan in a solid bed of mortar so the material does not flex when you stand on it. If the previous installer skipped this critical step, years of stepping into the shower causes the base to bend back and forth until the stress finally snaps the material.

Hard Water Degradation

Here in the midwest, our municipal and well water is notoriously hard on delicate plumbing fixtures and seals. Over a decade or two, high levels of calcium and magnesium eat away at rubber gaskets, drain seals, and the grout lines holding your shower together. This constant mineral scaling accelerates the breakdown of the waterproofing barriers, leading to stubborn leaks that require a full tear-out to fix properly.

Corroded Rough-In Plumbing

Sometimes the shower surround itself looks properly fine, but the hidden plumbing behind the wall is actively failing under pressure. Old galvanized steel pipes rust from the inside out, and ancient brass shower valves eventually seize up or start leaking behind the drywall. When the plumbing infrastructure hidden in the walls reaches the end of its lifespan, the only reliable solution is to open the wall and replace the rough-in plumbing alongside a new shower enclosure.

Improper Waterproofing Membranes

Many older showers were built using nothing more than green moisture-resistant drywall and standard tile grout to hold back the daily water flow. Grout is highly porous, meaning it absorbs water and relies entirely on the waterproof membrane hidden behind the wall to protect the house. If that membrane was installed incorrectly, or omitted entirely by a rushed contractor, water wicks straight into the wooden studs and destroys the structural integrity of the bathroom.

What to Expect During Your Shower Installation Visit

When our team arrives at your home, we do not just slap a new piece of plastic over an old, rotting problem. We start by assessing the extent of any hidden water damage, checking the stability of the subfloor, and inspecting the condition of your existing drain and supply lines. We will talk you through exactly what needs to be replaced, what can be salvaged, and how we plan to make the new system watertight.

The tear-out process can be messy, but we lay down drop cloths and contain the debris to protect the rest of your house. Once the old unit is out, we address the hidden mechanics by replacing old, corroded valves, ensuring the drain is properly aligned, and repairing any compromised subfloor. True Comfort Heating, Cooling and Plumbing ensures the structural foundation is sound before we ever bring the new shower pan into the room.

Finally, we install the new shower pan by setting it in a solid mortar base so it never flexes under your weight. We secure the walls, install the new fixtures, and run a rigorous leak test to verify every connection is completely sealed. We make sure that when our trucks leave your driveway, you have a solid, dependable, and completely watertight shower that will last for decades.
