Shower Pan Replacement
A Watertight Base Rebuilt Right
Shower pan confirmed leaking, base cracked or floor tiles loosening from constant moisture? Our plumbers replace failed shower pans and liners, rebuilding the base to keep water out of your home.
Shower Pan Replacement for Failed Liners and Cracked Bases
The shower pan is the waterproof layer under your shower floor. In a traditional tiled shower, it’s a flexible liner, often made of PVC or CPE, set over a sloped mortar base and covered by another mortar bed and tile. In prefabricated showers, the pan is the molded acrylic, fiberglass or composite base itself. Either way, its job is to catch every drop that passes through tile and grout and send it to the drain.
Pans fail for several reasons. Liners get punctured by nails or screws during construction, aren’t turned up high enough on the walls or are folded incorrectly at corners. Some were installed without a proper pre-slope, so water pools beneath the tile. Prefab bases can crack when they weren’t fully supported underneath. Once a pan leaks, water escapes into the subfloor, walls and ceilings below, and replacing the pan is the only lasting solution.

Why a Leaking Shower Pan Can't Simply Be Patched
When a shower pan leaks, it’s tempting to look for a quick sealant fix. Unfortunately, the problem is almost always below the tile, where sealers can’t reach. Grout sealers and caulk may slow surface water briefly, but they don’t repair a punctured liner, a missing pre-slope or a crack in the base. Water continues to find its way through grout lines and into the failed pan, and the damage below keeps spreading unseen.
A lasting repair means removing the shower floor tile, the mortar bed and the old liner or base, then inspecting the subfloor and framing for rot. Usually the lowest row or two of wall tile must also come off, so the new liner can be properly turned up the walls. It’s a bigger job than a surface fix, but it addresses the cause and protects the structure of your home.
Why Customers Trust Our Shower Pan Replacements
A shower pan only works if every detail is right, and we don’t skip steps. Our licensed and insured plumbers confirm the pan is the true source before demolition, inspect and repair damaged subfloor, build a proper pre-slope and turn liners up the walls to the correct height. Drain connections are matched to the pan system, and every new pan is flood tested before any tile or finishes go on.

Benefits of Professional Shower Pan Replacement
Replacing a failed shower pan stops the hidden leaks that rot subfloors, damage ceilings and grow mold behind walls. A correctly sloped base drains completely, keeping grout and tile dry and clean. Proper liner turn-ups and corners prevent water from escaping at the edges. Flood testing confirms the pan holds water before finishes are installed. And a rebuilt base restores a solid, stable floor that won’t crack tiles or flex underfoot.

Choosing a Replacement Shower Pan System
Replacing a shower pan gives you a chance to choose the waterproofing method that suits your shower design, budget and timeline best.
Traditional mortar beds with a flexible liner are proven and adaptable to any size or shape. Pre-sloped foam pan systems with bonded waterproof membranes install faster, are lighter and keep water at the surface of the assembly, so the mortar bed doesn’t stay saturated beneath tile.
Prefabricated bases in acrylic, solid surface or cast polymer offer the quickest installation and minimal maintenance, with no floor grout to seal. Each system needs a compatible drain. We’ll explain the trade-offs, coordinate with your tile installer and install the pan and drain correctly for the system you choose.
How Our Shower Pan Replacement Works
We confirm the pan is leaking through testing that isolates it from the valve, drain and walls before recommending replacement.
You’ll receive a plan covering demolition, subfloor repair, pan system, drain, tile coordination and cost. The shower floor and lower wall tile are removed, the old pan is taken out and the subfloor and framing are inspected. Damaged wood is repaired, and the drain is prepared or replaced.
The new pre-slope, liner or pan system is installed with proper turn-ups and drain connections. A flood test runs for a set period, commonly a full day, to confirm the pan holds water. Once it passes, tile or the base finish is completed, and the shower is tested again.

Shower Pan Replacement Questions Answered
Can a leaking shower pan be repaired?
Rarely. The damage is usually beneath the tile, so lasting repairs require removing the floor and replacing the liner or base.
Will the wall tile need to be removed?
Usually only the bottom row or two, so the new liner can be turned up the walls properly. Most wall tile stays in place.
How long does shower pan replacement take?
Typically several days, including demolition, subfloor repair, pan installation, a flood test and tile work, depending on the system chosen.
What causes shower pans to fail?
Punctured liners, poor turn-ups, missing pre-slope, unsupported bases and simple age are common causes of shower pan failure and leaks.
Is a foam pan system better than mortar?
Foam systems install faster and keep water near the surface. Mortar beds remain reliable and flexible. Both work well when installed correctly.
