Blanco Bathroom Remodeling: The South Florida Owner’s Guide
Blanco bathroom remodeling in South Florida typically runs $9,000-$28,000 for a full renovation, with smaller baths starting around $5,000. We stock and install Blanco-compatible fixtures, vanities, and hardware across their Silgranit, Subline, and Andano series, usually with same-week scheduling in Broward and Miami-Dade. Most homeowners realize something’s wrong when their Blanco sink starts staining, cracking, or the drain assembly seizes after years of hard water exposure.
Which Blanco Models This Applies To
Blanco’s bathroom lineup breaks into three main families you’ll see in South Florida homes: the ceramic Andano series, the Silgranit composite line in PuraDur II finish, and the steel Subline undermounts. The model number lives on a sticker under the basin rim or inside the cabinet on the original spec sheet. Silgranit sinks carry a 4-digit code starting with 5 (like 521-xxx for the Precis collection), while Andano ceramics use 5- or 6-digit SKUs.
Here’s where owners get tripped up: Silgranit drains aren’t interchangeable with standard 3.5-inch basket strainers. Blanco uses a proprietary 90mm opening with a tapered seal. Drop in a big-box replacement and you’ll get slow drainage, odor backflow, or a cracked flange from over-torquing. We carry both OEM Blanco drain kits and a German-made aftermarket equivalent that matches the taper exactly. For vanities and cabinets, Blanco doesn’t manufacture their own; they partner with regional cabinet makers. If your Blanco-labeled vanity is swelling at the toe kick or hinges are pulling out, the fix usually involves a KraftMaid or Wellborn-compatible cabinet box rather than chasing a “Blanco” part that doesn’t exist.
Signs Your Blanco Bathroom Remodeling Is Failing
- Silgranit surface whitening or chalking. The PuraDur II seal breaks down from chlorine and salt air, especially in coastal South Florida zip codes. What looks like soap scum is actually micro-pitting that’s trapping minerals. Left alone, it penetrates to the composite layer.
- Drain assembly stuck or spinning freely. The brass post in Blanco’s pop-up mechanism corrodes from our mineral-heavy water. Once the crossbar seizes, you’re either snapping the lift rod or stripping the threads trying to force it.
- Undermount sink sagging below the countertop. Silgranit is heavier than porcelain, around 18-22 lbs for a standard basin. If the original installer used generic clips instead of Blanco’s reinforced bracket kit, the epoxy fails and the rim drops. We’ve rescued three in Coral Gables this year alone.
- Vanity cabinet delamination at the sink cutout. Blanco’s tight reveal specs (1/8 inch overhang max) leave almost no margin for water migration. Steam from daily showers in unventilated South Florida baths swells MDF cores within two to three years.
- Faucet base wobble or supply line seepage. Blanco’s faucets use European 3/8-inch flex lines, not the standard 1/2-inch compression fittings common in U.S. hardware stores. Mix the two and you get thread damage and slow leaks that rot the cabinet floor.

|---|---|---|
| Small bathroom remodel | $5,000-$12,000 | Demolition, Blanco fixture swap, new vanity, paint, basic tile |
| Full bathroom remodel | $9,000-$28,000 | Gut to studs, Blanco Silgranit or Andano install, custom shower, flooring, electrical |

What drives the spread? Three things: whether we’re working with existing plumbing locations, if the wall behind the vanity needs mold remediation (common in older South Florida condos with original plaster), and your tile selection. Blanco’s Silgranit in anthracite or white costs the same; it’s the surround work that moves the needle. We quote parts and labor separately before we start. No surprises.

DIY or Call Us?
Here’s what you can safely check yourself: the model sticker location, whether the drain basket turns by hand (don’t force it), and whether the sag is in the sink or the cabinet box. A flashlight and a level tell you most of that in five minutes.
Where DIY goes wrong fast: Silgranit’s composite structure cracks if you over-torque the drain nut. The spec calls for 8-10 Nm, which most homeowners gauge by feel and overshoot by double. Worse, if you’re dealing with a glued undermount, heat-gun removal without supporting the basin sends it through the cabinet below. And anything involving shutoff valve replacement in South Florida’s original copper or polybutylene means you’re opening a wall. We’ve been called in after DIY attempts that turned a $1,200 sink swap into a $4,000 wall-rebuild job. Do it right the first time or you’ll do it twice - and the second time always costs more.

FAQs
With proper care, 15-20 years, though coastal salt air and chlorine-heavy municipal water can shorten that to 10-12 if the PuraDur seal isn’t maintained. We recommend annual resealing with Blanco’s own compound, not generic wax. Call (844) 665-0162 to add that to your install.
Surface scratches, yes. Structural cracks or chips deeper than 2mm, no. The composite layers delaminate once moisture penetrates, and repair epoxies don’t bond to the acrylic matrix long-term. We’ve never seen a “fixed” Silgranit crack hold past two South Florida summers. Replacement is the only permanent solution.
Two to four weeks for a standard 5×8 foot bath, assuming no plumbing relocation. Custom tile work, imported fixtures, or condo board approvals in buildings like those along Brickell or Fort Lauderdale beachfront add a week. We build a day-by-day schedule before demolition starts.
We carry Silgranit drain kits, bracket hardware, and the common faucet cartridges for Blanco’s current lines. Specialty colors or discontinued models we pull from our distributor in Miami Gardens, usually next-day. If you’re in a bind, call (844) 665-0162 with your model number and we’ll confirm what’s in the van.
