Fast, Reliable Bathroom Remodeling Across Sausalito
A full bathroom remodel in Sausalito runs $9,000 to $28,000, and the work typically takes two to four weeks once permits are approved. The spread is real because hillside homes here often need subfloor repairs before any tile goes down. Flat-lot houses in Mill Valley or Corte Madera rarely see that first stage. If you’re planning a remodel on a Sausalito slope, you need a contractor who prices the structure first, not just the surface. Call Mason Remodeling at (803) 680-2547 for a written estimate that accounts for your foundation before we touch a single fixture.
We’ve worked on raised-foundation bathrooms in the Banana Belt and the hills above Caledonia Street. The job starts under the floor, not on top of it. That’s the difference between a quote that holds and one that grows after demolition.
Why Mason Remodeling Is Sausalito’s Preferred Bathroom Remodeling Company

Sausalito homeowners call us because we send a name and a photo before the crew arrives. Every technician is background-checked and identity-verified under The Threshold Standard, a process we’ve run since 2004 as part of the Threshold Group family. When the doorbell rings, the person standing there is the person you approved. Uniform, photo ID badge, no exceptions.
We also put the price in writing before any work starts. Not a rough verbal range. A written line-item scope. That matters in Sausalito, where a bathroom on a hillside often hides structural work that unscrupulous bidders leave out on purpose, then add back as change orders after the tile comes up. Our quotes account for subfloor, load-bearing joists, and drainage up front.
And our 365-Day Done Right Promise covers the finished work for a full year from completion. If something isn’t right, we return and fix it at no charge. That’s the whole promise. Call (803) 680-2547 and a live person answers, 24 hours a day, every day.
Styles & brands we work with







Bathroom Remodeling Contractor in Sausalito
A Bathroom Remodeling Contractor in Sausalito does more than swap a tub for tile. On a hillside lot, the job often begins with structural framing. Homes built in the 1950s and 1960s on Sausalito’s slopes, especially around Wolfback Ridge and the 94965 ZIP, typically sit on raised foundations with small crawlspaces. When we open the floor, we find what decades of moisture did. That’s where the real work starts. A licensed contractor handles the rough-in, the inspection, and the finishes in sequence, and the permit gets signed off before the walls close.
You need a Bathroom Remodeling Contractor here when the scope includes moving a toilet, opening a load-bearing wall, or replacing rotted subfloor. If it’s a cosmetic refresh with a new vanity and the plumbing stays put, the structural piece may be minimal. We’ll tell you which one you have before we quote.
Full Bathroom Remodeling
Gut to studs, new subfloor where needed, new plumbing rough-in, shower pan or tub, tile, vanity, fixtures, and finishes. In Sausalito, plan for $9,000 to $28,000 depending on square footage, hillside access, and whether joist repairs come into play.
Small Bathroom Remodel
A compact bath off a hallway or a guest bath under the eaves. $5,000 to $12,000 in Sausalito. Scope includes a new vanity, toilet, tile, and fixtures, with the plumbing routed through existing walls to keep costs down.
Walk In Shower in Sausalito

A Walk In Shower in Sausalito costs $4,500 to $12,000 installed, and it’s one of the smartest moves for a hillside bath with a small footprint. Curbless or low-curb showers open up the room, and they eliminate the step-over that older tubs force on knees and hips. We build them with a properly sloped mortar bed, a waterproofing membrane, and a Schluter strip – the metal trim that seals the edge where tile meets flooring.
In Sausalito, a walk-in shower often means pulling out a 60-inch tub that has sat on a soft subfloor for forty years. The old tub wasn’t leaking because it failed. The floor underneath gave way first. That’s the hillside reality. We repair the structure, set the drain, and slope the pan so water moves toward it. Then we tile. You get a shower that drains correctly from day one because the floor under it is solid.
Walk-In Shower Installation
For a standard 60×30 footprint with a recessed pan, tile walls, and a glass panel or door, Sausalito homeowners typically pay $4,500 to $8,500. Custom tile work, a linear drain, or a full glass enclosure pushes toward the top of the range.
Tub-to-Shower Conversion
$3,500 to $10,000 in Sausalito, depending on whether we’re reusing existing plumbing locations or moving the drain. The drain move is common on hillside floors where the old tub sat against a joist. We sister the joist, move the drain, and slope the new pan. Permit covers the rough-in; inspection verifies the slope before tile.
Trusted Brands We Service in Sausalito
We install Kohler, Moen, Toto, and Grohe fixtures, KraftMaid and Wellborn cabinetry, and Cambria, Silestone, and Caesarstone surfaces. For compact Sausalito baths, we also stay current on prefab systems from Abodu and Cover, which are useful references for off-site components that fit a tight hillside access. We coordinate delivery and staging with the homeowner, so materials don’t sit in the rain on a slope before install day.

AfterCommon Bathroom Remodeling Problems We See in Sausalito Homes
- Soft subfloor around the toilet flange. Slow leaks run under the tile for years, especially in 1950s raised-foundation homes where the crawlspace is too tight to spot the damage early. By the time the tile comes up, the subfloor needs replacement before any new fixture goes in.
- Rotted joists under the tub or shower pan. Sausalito homes on slopes drain downhill, which means any leak follows the joist line. A quote that ignores the joist will not hold once the framing is exposed.
- Hillside access constraints. Crews can’t park a debris trailer on a 45-degree street. We stage materials in smaller lots, carry panels and tile by hand in some spots, and plan for that time in the calendar, not as a surprise.
- Skipped permits coming back to bite at resale. A bathroom remodel without a rough-in inspection is a liability when the next buyer opens the wall. We pull the permit, schedule the inspection, and leave the sign-off for you.
Pricing for Bathroom Remodeling in Sausalito, CA
These are the real numbers we write into Sausalito contracts. The ranges reflect what we see on hillside jobs once the structure is exposed. A flat-lot bath might land at the low end. A sloped lot with a soft subfloor lands at the high end. Either way, the number is in writing before demolition starts.

What changes the price once work begins? A joist that’s rotted further than the initial inspection showed. A drain that has to move because the new shower pan doesn’t line up with the old rough-in. A wall that opens up to reveal plumbing that was never vented correctly. We explain all of this in the written scope before we start, and our estimate covers what we can see. The rest we price as a clean line-item change order, approved by you before we proceed. Call (803) 680-2547 for a free written estimate.

FAQs About Bathroom Remodeling in Sausalito
Yes, if you’re moving plumbing, opening walls, replacing subfloor, or changing the layout. Sausalito building codes apply to any structural or plumbing change, and skipping the permit skips the inspection that protects you at resale. We pull the permit and schedule the inspection as part of the contract.
A full bath remodel in Sausalito runs $9,000 to $28,000. A small bath runs $5,000 to $12,000. Hillside foundations drive the high end. Call (803) 680-2547 for a written line-item quote with the price set before any work begins.
Because the subfloor work is often structural. Homes on slopes sit on raised foundations with small crawlspaces, and damage under the tile has to be repaired before the new bathroom goes in. That framing, permit, and inspection time adds days to the calendar that a flat-lot job in Mill Valley wouldn’t need.
A change order is a written addendum that prices work discovered after demolition that wasn’t visible during the initial estimate. A Sausalito bathroom on a hillside might need one for a rotted joist, a drain move, or unvented plumbing. We put the change order in writing and get your approval before the work proceeds.
Kohler, Moen, Toto, and Grohe for fixtures. KraftMaid and Wellborn for vanities. Cambria, Silestone, and Caesarstone for surfaces. If you’re in the Hurricane Gulch or Wolfback Ridge areas, the same brands apply. The difference on a hillside job is the subfloor under them, and that’s what our written price covers before the first tile is set.
