Does your shower floor creak or show cracks around the drain? We replace failing fixtures and rebuild structural subfloors right.
Does your fiberglass shower base creak and flex under your feet, have hairline cracks formed around your tub drain, or are water stains spreading across the ceiling below your bathroom? These issues indicate structural subfloor rot, failed pan liners, and cracked waste assemblies that caulk and cosmetic patches cannot resolve. DrainMaster provides complete, professional shower and tub installation and replacement services throughout Central Ohio to restore your plumbing system properly from the framing out.
The plumbing beneath a shower or tub carries significant weight and water volume. When a basin loses support or a drain assembly shifts, wastewater seeps directly into the building envelope. We pull out compromised basins, repair rotted joists and subflooring, and install modern fixtures that meet safety requirements and stand up to regular use.
A proper installation protects the structural integrity of your home. Many homeowners attempt to manage these failures with patches, but water continues to track along structural joists out of sight. Our team solves the root mechanical problems to help prevent leaks from spreading through your walls or subflooring.
The floor of your shower base or bathtub sags, gives way, or squeaks under your normal body weight. This movement means the mortar bed supporting the fixture has deteriorated, or leaks have completely rotted through the plywood subfloor beneath the unit. Ignoring this flex splits the drain shoe off the trap assembly and will cause the basin to fail.
Dark water rings, peeling paint, or wet patches appear on the drywall ceiling or walls in the room directly beneath your tub or shower. This symptom confirms that your shower pan liner has torn, the overflow gasket has rotted, or the drain connection has separated due to floor settlement. Leaving this untreated allows wastewater to saturate subfloor materials and rot out supporting structural joists.
Fine, spiderweb-like cracks spread outward across the gelcoat or acrylic surface surrounding the tub or shower drain. Heavy foot traffic and improper subfloor support flex the plastic until mechanical stress fractures tear through the surface. Water escapes through these structural fractures during use, completely bypassing the drain pipe and drenching the raw wood framing underneath.
Water begins pooling around baseboards outside the bathroom stall, or tile grout lines on the wet wall start crumbling and popping free. Behind the wallboard, the pressure-balanced shower valve body or aged supply lines have sprung pinhole leaks, or the waterproofing membrane behind the surround has deteriorated completely. This constant moisture saturates wall studs and surrounding insulation, weakening adjacent room walls.
A persistent musty or sewer gas odor rises around the fixture base even after you clean the surface and clear the visible drain. This happens when an improperly sloped or unvented waste line constantly pulls water out of the trap, or leaking water under the apron has created stagnant water in the subfloor. Surface cleaning chemicals cannot address moisture and sewer gases trapped deep within compromised wall and floor cavities.
Continuous ground movement shifts residential foundations and twists upper-floor joist framing out of level over time. The resulting torque stresses rigid drain connections, cracks tile assemblies, and pulls preformed acrylic units away from the wall studs. Correcting this requires stripping the bathroom down to the rough framing, sistering damaged joists, leveling the subfloor, and installing a heavy-duty unit designed to withstand ground movement.
Lightweight acrylic and fiberglass tubs are frequently installed directly onto bare subfloors without pouring a supportive structural mortar bed underneath the basin. Without a cement base to carry human body weight, the hollow floor of the tub continuously flexes, stretches, and rubs against the plywood subfloor every time you step inside. Over time, structural fatigue causes the thin basin bottom to crack open around the drain aperture and release water into the floor framing. A proper replacement involves setting the new fixture into a thick, hand-troweled mortar bed that cures to help prevent movement.
Older plumbing systems often retain original galvanized steel drain arms, cast-iron traps, or mismatched brass waste-and-overflow kits tied directly into newer plastic piping. Over time, electrolytic corrosion between dissimilar metals eats away at the threaded joints under the tub shoe, causing the metal to rust through from the inside out. These failures hide completely beneath the tub apron until extensive water damage damages the ceiling below. Technicians must cut back this decaying metal to the main stack, install modern solvent-welded PVC drain pipes, and run smooth, properly pitched lines for the new fixture.
Traditional site-built tile showers rely on lead, copper, or PVC pan liners installed beneath the finished mud bed to catch incidental moisture and route it to the weep holes. Over time, alkaline reactions from tile thinset break down vinyl pans, copper pans corrode, and normal house movement tears the seams at the corners. Once this pan liner fails, water saturates the mortar bed completely and migrates directly into the timber frame every time you turn on the water. Replacing a failed pan requires tearing out the entire tile surround, reconstructing the curb and subfloor, and installing an impervious, modern waterproofing enclosure.
When DrainMaster arrives at your property, we treat the project as a full structural and mechanical overhaul, not a cosmetic cover-up. Our technicians start by evaluating the existing enclosure, addressing moisture intrusion, and accessing the plumbing rough-in from access panels or the floor below. We take photos and video of the subfloor, trap assembly, and supply lines to show you exactly what is happening behind the walls before any demolition starts.
Before demolition begins, we protect your flooring, map out the water shutoffs, and isolate the supply lines to ensure clean, controlled work. Once the old fixture is extracted, we inspect the floor joists and wall framing for rot, making any necessary carpentry repairs to create a level, square base. We replace outdated piping, rebuild the drain and overflow with modern solvent-welded PVC, install a brand-new pressure-balanced shower valve, and set the new basin or tub directly into a solid base. Every phase is pressure-tested for watertight integrity before the final fixtures and finishes are set, ensuring long-term reliability for your Central Ohio home.
Our technicians walk you through every step of the completed installation, explaining how the new pressure-balanced valves work and how to access critical shutoffs. We clean the entire workspace, remove all scrap materials, and leave your bathroom ready for regular use. You receive detailed documentation and photographic proof of the sound plumbing installed behind your newly finished walls.
DrainMaster brings fully equipped plumbing service trucks and complete rough-in installation capabilities to homeowners and residential properties across the entire metro area.
Replacing an old tub or shower base provides the ideal opening to update other mechanical components behind the wall. We regularly coordinate fixture overhauls with whole-home repiping to address constricted pipes, balance water pressure, and ensure your new shower receives steady hot and cold volume. Our technicians also install high-output units through our water heater installation services so your new soaking tub receives ample hot water during use.
A cracked shower basin, spongy tub floor, or rough-in leak will quietly damage your floor joists and cause mold behind your walls every time someone turns on the tap. DrainMaster delivers honest assessments, complete tear-outs, and reliable plumbing solutions backed by extensive hands-on mechanical experience.
