Blanco Bathroom Remodeling: The San Francisco Owner’s Guide
We remodel bathrooms around Blanco fixtures, vanities, and sinks on a regular basis, and the installed cost in San Francisco runs $10,620 to $33,040 depending on scope, substrate condition, and whether you’re keeping the existing rough-in plumbing. That price includes a written scope, permits pulled, and the 365-Day Done Right Promise backing every fixture swap, wall repair, and tile run. Most San Francisco homeowners call us after a Blanco sink or vanity has been in the house 8 to 15 years, and what looked like a simple faucet replacement has turned into a wall-open job because the substrate behind the vanity finally gave out.
Blanco makes good fixtures. What fails around them in San Francisco is usually the house, not the hardware: fog-driven moisture in older Outer Sunset and Richmond District walls, settling foundations in the Mission and Noe Valley, and framing that has shifted enough to pull a Blanco undermount sink’s silicone bead loose. If you own a Blanco and the bathroom is showing its age, this page tells you what to expect, what it should cost, and how we work.
Which Blanco Models This Applies To

Blanco bathroom product lines fall into a few families: the sinks themselves (undermount, drop-in, and vessel designs), the Silgranit and ceramic materials, and the vanities or vanity cabinets sold under the Blanco name in partnership with cabinet manufacturers. The compatibility gotcha most people hit: Blanco Silgranit sinks have a tighter radius at the bowl corner than standard stainless or fireclay , which changes the faucet reach you need and the cutout template for the countertop. If a contractor cuts a generic opening, the Blanco sink will never seat correctly, and you will fight leaks at the rim for the life of the job.
The second gotcha is the drain assembly. Blanco uses a European-standard 3.5-inch strainer opening on most Silgranit models, not the 4-inch basket opening common on commercial-grade stainless. If you buy a standard basket strainer off the shelf, it will not seal. We keep the correct Blanco-compatible drain hardware in stock or order it from a documented distributor before the job starts, so there is no surprise trip to a supply house mid-demo.
On OEM versus aftermarket: for a Blanco-specific part like a drain assembly, mounting clip, or overflow gasket, we recommend OEM or a documented equivalent that matches the exact hole pattern. Cheaper generic parts are a false economy here. A $75 generic drain that leaks in a year costs more to replace than the $140 OEM drain that would have lasted ten. For non-Blanco components around the fixture, such as supply lines, shutoff valves, and substrate board, we use contractor-grade materials with manufacturer specs we can hand you in writing.
Bradford Remodeling Co San Francisco is an independent remodeling contractor. We are not affiliated with Blanco, and we install Blanco-compatible products alongside KraftMaid and Wellborn cabinetry, Cambria and Silestone surfaces, and Kohler and Moen fixtures.
Styles & brands we work with







Signs Your Blanco Bathroom Remodeling Is Failing
- Dark staining or softness at the vanity base – Water has been wicking under the vanity for months, usually from a slow drain leak or a failed silicone bead at the Blanco sink rim. By the time you see it, the cabinet toe-kick and bottom panel are often rotten.
- A faucet that drips or runs weak even after new cartridges – Blanco faucets run on a ceramic disc cartridge, and hard water in San Francisco will score those discs over time. If you’ve already swapped the cartridge and it still drips, the faucet body is worn, and the fix is replacement, not another cartridge.
- Countertop pulling away from the Blanco sink rim – In San Francisco’s older wood-frame houses, especially balloon-framed homes in the Outer Sunset, seasonal movement will break the bond between a stone countertop and an undermount Blanco sink. The sink drops a few millimeters, the silicone bead tears, and you get water running down the cabinet face.
- Efflorescence or mineral crust on the Blanco sink surface – Blanco Silgranit and ceramic surfaces resist staining, but seven-plus years of hard San Francisco water will leave a calcium crust. It can be restored with the right non-abrasive cleaner, but if the surface is etched through, it is a replacement consideration.
- Vanity drawers that bind or drop out of their slides – Older Blanco vanity cabinets used side-mount slides that wear out after a decade of daily use. New drawer boxes with soft-close under-mount slides bring the vanity back to new without pulling the cabinet.
Replacement Cost & What’s Included

A full Blanco bathroom remodel in San Francisco runs $10,620 to $33,040. A smaller refresh, such as a vanity replacement, new Blanco sink, faucet, and a tub-to-shower conversion in a small bath, falls in the $5,900 to $14,160 range. A walk-in shower with new Blanco-compatible fixtures and full tile surround lands between $5,310 and $14,160.
What drives the range? Three things. First, the condition of the wall substrate and floor framing once the old vanity and tile come out. San Francisco pre-war homes hide surprises, and we price for what we can see before demo, then put any hidden conditions in a written change order before touching them. Second, the Blanco part itself: a simple drain assembly and faucet swap is one line item. Replacing a damaged Blanco vanity cabinet with a matching or upgraded cabinet is a different line item. Third, tile scope: a 3-by-5 shower surround is a one-day tile set plus waterproofing. A full floor-to-ceiling bathroom in a larger master bath is a different job.
Every Bradford remodel in San Francisco includes a written price before work starts, permits pulled and inspections passed, a documented scope you sign, and the 365-Day Done Right Promise in writing at close-out. If any part of our work fails inside a year, we come back and correct it at no charge.

Here is the honest split. You can safely check your Blanco sink’s drain assembly yourself: shut off the water, put a bucket under the trap, and look for a cracked rubber gasket or a loose compression nut. That’s a $12 part and thirty minutes for a careful homeowner. You can also remove and clean mineral build-up on a Silgranit sink with a non-abrasive pad and white vinegar. None of that requires opening a wall.
What you should not DIY is anything that involves a Blanco undermount sink that has dropped or a vanity that has been water-damaged. An undermount sink is supported entirely by the countertop and the bond to the stone. Once it drops, you do not know what is going on inside the cabinet until the countertop comes off. That is not a weekend job, and doing it wrong leaves you with a broken slab and a bigger bill. Same goes for any plumbing shutoff work in a San Francisco building with old galvanized supply lines: one wrong turn on a seized valve and you have a flood behind a wall.

FAQs
A Blanco Silgranit sink or faucet will normally last 15 to 20 years in San Francisco, but the silicone bond around an undermount sink typically needs re-sealing every 8 to 12 years because of seasonal humidity shifts. When that bond goes, the fix is a countertop reset, not a new sink. Call (831) 610-5598 for a straight assessment.
Usually not, because the rubber gasket or the strainer body itself is what fails, and neither is worth the labor to patch. We replace the drain assembly with the correct Blanco-compatible 3.5-inch hardware, which is the cheaper and longer-lasting fix. The new assembly matches the Blanco sink’s original hole pattern, and the work is covered by the 365-Day Done Right Promise.
A vanity-and-sink swap with the Blanco fixture staying in place is typically a two-to-three-day job. A full bathroom remodel with gut-and-rebuild, new tile, and new Blanco fixtures runs seven to fourteen working days depending on permit review and hidden framing conditions. We give you a written timeline alongside the written price, so you know the schedule before we start.
We keep the common wear items in stock: Blanco-compatible drain assemblies, faucet cartridges, supply lines, and mounting clips. Anything model-specific to a discontinued Blanco vanity or a custom Silgranit sink gets ordered through our documented distributor before demo starts, so there is no work stoppage waiting on parts. Call (831) 610-5598 and describe your Blanco model, and we will tell you exactly what is available before you commit to anything.
Only if we find hidden damage behind the walls that was not visible during the estimate, and if that happens, you will get a written change order with a new price before we touch it. We never add numbers at the door. That is the Garrison Standard, and it applies to every San Francisco job we run.
