Project Overview & Homeowner Objectives in Mars, Seven Fields & Valencia

In luxury master suites throughout Treesdale, Adams Ridge, Seven Fields, and custom residences in Mars and Valencia, PA, the #1 bathroom layout complaint is the oversized 1990s carpeted deck jetted tub paired with a cramped 36×36-inch framed fiberglass shower stall. For this homeowner off Route 228, we demolished the dated corner platform tub and alcove insert to engineer a zero-threshold curbless walk-in porcelain tile shower, a sculpted freestanding soaking tub, and a heated tile floor.

Property Profile & Pre-Renovation Challenges

Upon demolishing the existing builder-grade shower, we uncovered moisture-damaged OSB subflooring, an undersized 1.5-inch cast-iron/PVC trap, and an exhaust fan that vented moist air directly into the cold attic soffit—causing frost buildup on the roof sheathing every winter.

Scope of Work & Turnkey Trade Coordination

• Subfloor structural recessing and reinforcement for a true zero-entry curbless shower pan.
• Complete custom shower remodeling with continuous Schluter-KERDI waterproofing and linear trench drainage.
• In-house licensed plumbing, electrical radiant floor wiring, and HVAC exterior ventilation.

Waterproofing Engineering, Subfloor Deflection & In-House Mechanical Trades

Zero-Threshold Structural Framing & Schluter-KERDI Membrane

Delivering a watertight bathroom remodel in Mars and Seven Fields starts beneath the tile. To achieve a flush curbless entry without raising the main bathroom floor, our carpenters sistered the floor joists and recessed the wet-area subfloor between the framing bays, exceeding the strict L/360 deflection standard required for large-format porcelain. We installed a pre-sloped Schluter-KERDI pan pitched at 1/4-inch per foot to a brushed stainless linear drain, wrapping all walls, the built-in floating bench, and a dual-tier recessed shampoo niche with continuous KERDI waterproof membrane sealed with KERDI-FIX and KERDI-BAND.

In-House Plumbing, Radiant Heat Electrical & Moisture Exhaust

Our licensed plumbers upgraded the shower drain to a code-compliant 2-inch PVC line and installed PEX-A supply lines feeding a thermostatic mixing valve with independent volume controls for an overhead rain head and handheld wand, plus a floor-mounted tub filler along an insulated interior wall. Simultaneously, our electricians ran a dedicated 20-amp GFCI circuit to power a Schluter-DITRA-HEAT uncoupling membrane across the main floor, alongside wet-rated recessed LED shower cans and backlit anti-fog vanity mirrors.

Master Tile Craftsmanship & Adams Township / Seven Fields Code Compliance

Large-Format Porcelain Slabs & Stain-Proof Epoxy Grout

Our master tile setters laser-leveled 24×48-inch rectified porcelain slabs with 1/16-inch leveling clips and Ardex X77 mortar, finishing all joints with non-porous spectralock epoxy grout that never requires sealing and resists mildew.

Municipal Code Compliance & Western PA Freeze-Thaw Ventilation

To protect the attic from winter condensation during sub-zero Butler County nights, our HVAC team installed a Panasonic WhisperGreen 110-CFM humidity-sensing fan piped through R-8 insulated rigid metal ducting to a dedicated roof cap. All plumbing, electrical, and tempered 3/8-inch frameless Starphire glass enclosures met Adams Township and Seven Fields Borough UCC inspection standards.
