Why Mason Remodeling Is Fairfax’s Preferred Bathroom Remodeling Company
Fairfax homeowners don’t want a sales pitch. They want to know who’s walking through the door, what the job costs, and what happens if something isn’t right. We’ve built our reputation here on those three answers.
Every Mason Remodeling crew member arrives in a clean uniform with a photo ID badge, and you’ll receive their name and photo before the visit. That’s The Threshold Standard, and it’s been our practice since Isaac Pruett founded the company in 2004 as part of the Threshold Group. It matters in Fairfax, where many of our clients are home alone during the day or have young kids in the house.
We deliver a written price before any work begins. Not a ballpark. Not a verbal estimate that grows on the final bill. A line-item price you can review, question, and approve before we unpack a single tool.

When you call (803) 680-2547, a live person answers. No call trees. No voicemail loops. That’s the same number Fairfax customers use to reach us during a project, and it’s answered 24 hours a day, every day.
Styles & brands we work with
Small Bathroom Remodel in Fairfax
A Small Bathroom Remodel in Fairfax is often a full gut-and-rebuild of a compact 5-by-8 or 6-by-9 bath, and it’s the most common project we take on in the older homes around downtown Fairfax and the hills above Sir Francis Drake Boulevard. These bathrooms usually have original cast-iron tubs, dated tile, and vanities that have seen better decades. The goal is the same as a large remodel: a waterproof, well-ventilated space that works. The scale is smaller, which means the budget can be too.
Typical cost for a small bathroom remodel in Fairfax runs $5,000 to $12,000. A full bathroom remodel in Fairfax, with higher-end tile, a new tub or shower system, and custom vanity work, lands between $9,000 and $28,000.
What We Typically Replace
In a small Fairfax bathroom, we usually replace everything down to the studs: floor tile, wall tile, the tub or shower base, the vanity, the toilet, lighting, and the exhaust fan. Older Fairfax homes frequently have galvanized supply lines and cast-iron drain pipes. If those are present, we’ll bring them up to current code during the rough-in so your new bathroom doesn’t hide a plumbing problem behind a fresh tile wall.
Ventilation Matters in Fairfax’s Microclimates
Fairfax sits in a canyon that gets real fog from the coast and real heat in summer, and older homes here were built before modern ventilation standards. A small bathroom with a weak exhaust fan traps moisture, which is why we specify a properly sized fan and a timer switch on nearly every small remodel we do. It’s a small line item that prevents big problems later.
Shower Remodel in Fairfax
A Shower Remodel in Fairfax usually means one of two things: replacing a tired shower surround and pan in an existing footprint, or converting a rarely used tub into a walk-in shower. Both are popular in Fairfax because so many homes were built with a single full bath, and a better shower often makes more sense than adding square footage.
Shower replacement in Fairfax typically costs $3,000 to $8,500. A tub-to-shower conversion runs $3,500 to $10,000. If you’re building or expanding a walk-in shower with a frameless glass enclosure, plan for $4,500 to $12,000.
Walk-In Shower Installation
Walk-in showers are the most requested shower upgrade we handle in Fairfax, and for good reason: they open up a small bathroom visually and work better for older homeowners who want to avoid stepping over a tub wall. We install the waterproof pan, tile or solid-surface walls, and the glass enclosure with a Schluter strip – that’s the metal trim that seals the edge where tile meets flooring, and it’s standard on our shower work.
Frameless Glass Shower Enclosures
Frameless glass enclosures are the finish that makes a custom shower feel done. In Fairfax bathrooms with limited natural light, they’re worth the extra cost because they don’t create a visual barrier the way a framed enclosure does. We measure after tile is set so the glass fits exactly, and we handle the install with the same written-price guarantee as the rest of the project.
Trusted Brands We Service in Fairfax
We stock and install Kohler, Moen, and Toto fixtures, KraftMaid and Wellborn vanities, and Cambria, Silestone, and Caesarstone surfaces for Fairfax projects. We also work with specification-grade building partners like Abodu and Cover when a bathroom remodel is part of a larger home addition. Because we install these brands regularly in Fairfax, our crews know the installation requirements ahead of time. That means fewer surprises during rough-in and a faster path from demo day to final inspection.

AfterCommon Bathroom Remodeling Problems We See in Fairfax Homes
- Unpermitted additions and converted spaces. Many Fairfax homes have a bathroom or extra bedroom that was added without permits decades ago. Before we can remodel that space, we often have to document the as-built condition and file for retroactive permits, which adds time and paperwork but protects you at resale.
- Moisture damage hidden behind tile. Fairfax’s canyon climate pushes moisture into wall cavities, and older homes here often have tile set directly over drywall. We’ve opened walls to find mold and rotted subfloor that no one suspected until the tile came off. We’re not surprised by it, and we know how to fix it correctly.
- Galvanized supply lines and undersized venting. Homes built before the 1970s in Fairfax frequently have plumbing that won’t pass today’s rough-in inspection. If we find galvanized piping or a vent that doesn’t meet current code, we’ll flag it before the inspection so you don’t get hit with a surprise rework bill later.
- Scope creep without change orders. Fairfax homeowners sometimes request added tile patterns or a different vanity mid-project, and without a written change order that turns into a payment dispute at the end. We put every change in writing, with a price, before anyone makes it.

FAQs About Bathroom Remodeling in Fairfax
A typical full bathroom remodel in Fairfax takes 4 to 8 weeks from the day we start demo to the final walkthrough, and as-built review or retroactive permitting can add 1 to 3 weeks up front before construction begins. Small bathroom remodels and shower replacements usually run 2 to 4 weeks. Your written contract will include a schedule with the permit timeline, inspection dates, and a punch list date spelled out in plain language. Call (803) 680-2547 to get an exact timeline for your project.
Yes, you need a Marin County building permit for any bathroom remodel in Fairfax that moves plumbing, changes electrical, or alters the footprint of the room. The process involves a plan review, a rough-in inspection for plumbing and electrical after the walls are open, and a final inspection once finishes are complete. If you’re replacing fixtures without moving them, a permit may not be required, but we’ll confirm your specific scope with the Marin County Building Department before we start.
The three biggest cost drivers in Fairfax are the age of your rough plumbing, whether the space has unpermitted additions that need retroactive permitting, and the material allowances you select for tile, fixtures, and countertops. Galvanized supply lines and old cast-iron drains push a $9,000 project toward $14,000. Cambria or Silestone slabs above a written allowance add real money. We cover all of this in your written estimate, so you won’t discover it later. Call (803) 680-2547 for a free, itemized quote.
Yes, tub-to-shower conversion is one of the most common projects we complete in Fairfax, and it typically costs $3,500 to $10,000 depending on the size of the footprint, the condition of the drain and supply lines, and the finish level of the tile and glass. Fairfax homes often have a 5-foot tub alcove, which converts cleanly to a 5-foot walk-in shower with a 42- to 48-inch glass panel. We handle the plumbing relocation, waterproofing, and glass installation as one contract with one written price.
A Fairfax bathroom remodeling contract should list the exact scope, the written material allowances with brand and product names, the permit and inspection schedule, the payment schedule tied to completed milestones, and a written change-order process that requires your signature before any new work is priced or started. Our contracts include all of that, plus the terms of the 365-Day Done Right Promise in writing. If a contractor won’t put that on paper before you pay a deposit, you already have your answer.
Call (803) 680-2547 today to schedule your free bathroom remodeling estimate in Fairfax. We’ll come out, measure the space, talk through your options, and put a written price in front of you before you decide anything.
