Bathroom remodeling is a specialized service designed to transform one of your home's most critical spaces into something functional, durable, and built to last: Mosier Reisom Construction & Engineering goes beyond surface-level updates. We bring an engineering-led approach to every bathroom project, ensuring that waterproofing systems, structural integrity, and code compliance are never afterthoughts. Our process handles everything from design and material selection to sequenced installation and final inspection, delivering bathrooms that perform as well as they look.
With extensive experience across Lawrenceville, Gwinnett County, and the greater Atlanta area, our team understands the local building codes, climate considerations, and common challenges homeowners face during bathroom renovations. We've seen what happens when shortcuts are taken: premature tile failure, concealed water damage, and expensive rework: and we've built our standards to prevent those outcomes. Every bathroom remodel we complete is backed by detailed planning, documented waterproofing procedures, and a commitment to transparent communication from start to finish.
What a Bathroom Remodel Costs (Real Budget Ranges)
Bathroom remodeling costs in the Lawrenceville area vary based on project scope, material selections, and the complexity of plumbing or layout changes. Unlike vague estimates, we provide clear starting ranges so you can plan accordingly:
Guest Bathroom Refresh (Cosmetic Updates): Starting at $15,000–$25,000
This includes new fixtures, vanity replacement, updated tile or flooring, lighting upgrades, and paint. Plumbing and electrical remain in existing locations, minimizing structural work while delivering a refreshed, modern appearance.
Full Bathroom Remodel (Mid-Range): Starting at $30,000–$50,000
A complete renovation with layout modifications, upgraded shower or tub systems, enhanced waterproofing, new tile throughout, upgraded vanity and countertops, modern lighting, and updated ventilation. This range accounts for relocating plumbing lines, addressing framing or subfloor repairs, and meeting current code requirements.
Primary Bathroom Build (Premium Finishes & Custom Features): Starting at $50,000–$75,000+
This includes custom tile work, curbless showers with linear drains, built-in niches and benches, high-end fixtures, specialty lighting, upgraded ventilation systems, and premium materials like natural stone or large-format porcelain. Projects in this range often involve significant layout changes, structural modifications, or adding square footage.
Cost drivers that affect your final investment include tile selection (standard ceramic vs. natural stone or large-format porcelain), fixture quality, shower complexity (curb vs. curbless, niche count, bench installation), waterproofing system requirements, plumbing relocation distance, and finish-level choices. Labor typically accounts for 40% to 60% of your total budget: this reflects the skilled trades required for proper waterproofing, tile installation, and finish carpentry.
Timeline: What to Expect from Start to Finish
A properly executed bathroom remodel in Gwinnett County follows a sequenced timeline that prioritizes structural integrity and quality at every phase. Rushing this process invites problems that surface months or years later.
Design & Material Selection: 2–3 weeks
This phase locks in your layout, fixture specifications, tile and finish selections, lighting plan, and plumbing/electrical requirements. Decisions made here directly impact your construction timeline, so we work with you to finalize choices before demolition begins.
Permitting (If Required): 1–2 weeks
Projects involving plumbing relocation, layout changes, or structural modifications require permits in Gwinnett County. We handle permit applications, submissions, and coordination with local inspectors to keep your project compliant and on schedule. Learn more about permits in Gwinnett County.
Demolition & Framing Corrections: 3–5 days
Controlled demolition, debris removal, and addressing hidden issues discovered during demo: subfloor damage, outdated plumbing, inadequate framing, or previous water damage. This phase includes any necessary repairs or modifications to ensure a solid foundation for waterproofing and tile work.
Rough-In Work (Plumbing, Electrical, HVAC): 3–5 days
Installation of new plumbing lines, drain relocations, electrical circuits for lighting and outlets, exhaust fan ductwork, and any structural blocking required for grab bars or wall-mounted fixtures. Rough-in inspections follow this phase.
Waterproofing & Prep: 2–3 days
This is where engineering-led quality separates lasting bathrooms from future problems. We install manufacturer-specified waterproofing membranes, pan systems for showers, vapor barriers, and backer board: all documented and tested before tile installation begins.
Tile Installation & Grouting: 5–7 days
Shower walls, floors, tub surrounds, and floor tile are installed with proper substrate prep, thinset application, and grout curing time. Large-format tiles, intricate patterns, or natural stone require additional time for precision placement and curing.
Fixture Installation & Trim-Out: 3–5 days
Vanity installation, countertop templating and installation, plumbing fixture rough-in and trim, lighting installation, mirror and hardware mounting, and final paint touchups. This phase includes final inspections and testing of all fixtures.
Final Walkthrough & Punch List: 1–2 days
Detailed review of completed work, addressing any final adjustments, cleaning, and homeowner orientation on fixture operation and maintenance.
Total Timeline Range: Most bathroom remodels in Lawrenceville take 4 to 8 weeks from demolition to completion, depending on project complexity, material lead times, and inspection schedules. Custom tile work, specialty orders, or structural modifications extend timelines: we provide a detailed schedule during the design phase so you know exactly what to expect.
Waterproofing Standards: The System That Prevents Failures
Waterproofing is not a single product: it's an integrated system that requires proper sequencing, material compatibility, and installation precision. Poor waterproofing is the leading cause of bathroom failures, resulting in concealed leaks, mold growth, structural damage, and costly tear-outs years after completion.
Our Waterproofing Process Includes:
Manufacturer-Specified Systems: We use complete waterproofing systems from manufacturers like Schluter, Wedi, or Laticrete: not mix-and-match components. This ensures compatibility, warranty coverage, and proven performance.
Pan Testing & Flood Testing: Before tile installation, shower pans are flood-tested for 24–48 hours to verify no leaks exist in the waterproof membrane. This step catches problems when they're fixable, not after tile is installed.
Proper Substrate Prep: All backer board, waterproof membranes, and shower systems are installed per manufacturer specifications with appropriate fastener spacing, seam treatment, and corner detailing.
Drainage Slope Verification: Shower floors are built with proper slope to drain (minimum 1/4" per foot) to prevent standing water and ensure complete drainage.
Expansion Joint Planning: Large-format tiles and floor-to-wall transitions require expansion joints to prevent tile cracking from building movement or thermal expansion.
Vapor Management: Moisture barriers are installed to prevent vapor transmission through walls and ceilings in steam-prone areas.
Documentation: We photograph each phase of waterproofing installation, providing you with records that demonstrate system integrity and compliance with manufacturer requirements.
Tile is not waterproof. Grout is not waterproof. The waterproofing system beneath them is what protects your investment: we build that system correctly the first time.
