Blanco Bathroom Remodeling: The Sherman Oaks Owner’s Guide
Blanco bathroom remodeling in Sherman Oaks typically runs $9,000-$28,000 for a full renovation, with fixture-specific updates starting lower depending on scope. We stock and install Blanco-compatible sinks, faucets, drains, and accessories across the popular Precis, Quatrus, and Vintera series, and we carry common replacement cartridges and mounting hardware on our trucks. Most homeowners discover a Blanco fixture is failing when the drain assembly starts seeping around the rubber gasket, the faucet develops a drip that won’t stop with a new washer, or the Silgranit sink shows hairline cracking near the drain hole from thermal shock in older Sherman Oaks homes with uneven water heater output.
Which Blanco Models This Applies To
Blanco’s bathroom lineup breaks into three families that use different mounting systems, and matching the right part means checking the label under the sink or inside the cabinet door before you order anything.
- Precis and Quatrus undermount sinks use a proprietary bracket-and-channel system with a 3/8-inch threaded rod spacing that differs from Kohler and American Standard by a quarter inch. The OEM mounting kit is part B440196; we’ve seen aftermarket kits that claim compatibility but lack the rubber isolation grommets that prevent Silgranit from stress-cracking against the stone countertop.
- Vintera farmhouse and apron-front sinks require a reinforced cabinet base and a specific drain assembly with an extended tailpiece, part B440299, because the thicker fireclay body sits lower in the cabinet than standard drains accommodate.
- Linus, Alta, and Culina faucet lines share a ceramic disc cartridge, part B440188, but the trim sleeve diameter varies between the compact Linus and the commercial-scale Alta. The cartridge itself is interchangeable; the trim is not.
We source OEM Blanco parts through the same distributors that supply the Galleria-area kitchen showrooms, and we keep aftermarket equivalents from Danco and BrassCraft on the truck for same-day resolution when the OEM part is back-ordered. For Silgranit sinks, we recommend OEM drain assemblies only; the thermal expansion coefficient of that composite material tolerates fewer shortcuts than cast iron or stainless.
Signs Your Blanco Bathroom Remodeling Is Failing

- Persistent drip from the faucet spout or base. The ceramic disc cartridge has developed a groove where the two polished discs meet, usually from sediment scoring the surface. Sherman Oaks water runs moderately hard, around 12-15 grains per gallon, which accelerates this wear compared to soft-water coastal zones.
- Water pooling under the Silgranit sink bowl. The drain flange gasket has hardened or the installer overtightened the locknut and compressed the rubber beyond recovery. In homes near the Ventura Boulevard corridor with original galvanized supply lines, pressure spikes from pipe scale dislodging can finish off an already aged gasket.
- Loose faucet handle with increasing play. The set screw in the handle hub has backed out, or the brass stem has worn where it engages the cartridge. Left unchecked, the handle will strip the stem splines and you’ll need both parts instead of just tightening a screw.
- Discoloration or rough texture on Silgranit surface. This is not a part failure but a material response to abrasive cleaners or prolonged exposure to hair dye, bleach, or certain essential oils. The surface layer has degraded; replacement is the only fix that restores the original finish.
- Slow drain that doesn’t respond to snaking. The Blanco pop-up assembly uses a horizontal rod with a specific bend radius; cheap aftermarket replacements often sit too low in the drain path and catch debris. We’ve pulled rod assemblies from big-box stores that reduced flow diameter by nearly half.

AfterReplacement Cost & What’s Included
A Blanco-focused bathroom remodel in Sherman Oaks falls within our standard $9,000-$28,000 range, with fixture-specific replacements starting lower depending on how much surrounding work is required.
| Scope | Price Range | What’s Included |
|---|---|---|
| Blanco faucet cartridge replacement | $180-$340 | OEM cartridge, labor, leak test, 365-Day Done Right Promise |
| Blanco drain assembly replacement | $220-$420 | OEM drain kit, reseal to countertop, disposal of old assembly |
| Blanco sink replacement (Silgranit) | $1,800-$3,400 | Sink, mounting hardware, cutout modification if needed, caulk/seal |
| Full bathroom remodel with Blanco fixtures | $9,000-$28,000 | Demolition, rough plumbing, tile, fixtures, trim, permits, final inspection |
What drives the range: access (pedestal sinks take longer than vanities), countertop material (quartz requires a different cutout approach than laminate), and whether we’re matching existing Blanco finishes that have been discontinued. Under Clause 1 of the Haven Standard, you get the written price before anyone picks up a tool. No change proceeds without a signed change order. We’ve finished 4,000-plus projects within a few percent of the agreed number by sticking to that discipline.
DIY or Call Us?

There’s a clear line between what you can check safely and where the job turns into something that risks your countertop, your cabinet, or your warranty coverage.
What you can do: confirm the model number from the label under the sink, photograph the existing assembly from multiple angles, and test whether the leak is from the supply line (tighten with a wrench, gently) or the drain (don’t overtighten; Silgranit cracks under excessive compression). Turn off the angle stops before you touch anything. If you don’t have angle stops, that’s your sign to stop and call.
Where DIY goes wrong: cutting a Silgranit sink opening without the correct template, using a standard drain assembly in a Vintera fireclay sink and ending up with a two-inch gap to the trap, or forcing a cartridge into a corroded valve body and splitting the brass. We’ve been called to three Sherman Oaks jobs in the past year where a homeowner cracked a $900 Precis sink trying to save $200 on installation. Measure twice, write it down, then build it. If you’re not certain of the measurement, call (213) 221-0788 and we’ll schedule a free estimate with a written quote you can screenshot and compare.
FAQs
Blanco ceramic disc cartridges last 10-15 years with normal use; Silgranit sinks often reach 20-plus years unless subjected to thermal shock from sudden temperature swings, which happens more in older Sherman Oaks homes with tankless retrofits that send uneven hot water. Hard water at 12-15 grains per gallon shortens cartridge life by roughly 20 percent compared to soft-water markets. Call (213) 221-0788 for an exact quote on replacement - estimates are free.
Usually, yes. A cartridge swap fixes 80 percent of Blanco faucet leaks; the body and spout rarely fail. Replacement makes sense only when the finish is worn through or the valve body has cracked from freeze damage, which we see occasionally in unheated garage bathrooms near the hills. Call (213) 221-0788 for an exact quote - estimates are free.
A faucet cartridge or drain assembly replacement takes 1-2 hours. A full sink replacement with countertop modification takes a half day. A complete bathroom remodel runs 2-4 weeks depending on tile selection and permit timing with the City of Los Angeles. We pull permits and schedule inspections as part of the written scope. Call (213) 221-0788 for an exact quote - estimates are free.
We carry cartridges, drain assemblies, and mounting hardware for the Precis, Quatrus, and Vintera lines. Silgranit sinks and fireclay farmhouse models are ordered to color and finish, typically 3-5 business days from our distributor in the San Fernando Valley. We don’t markup materials; the price on your written quote matches our distributor invoice plus labor at our standard rate. Call (213) 221-0788 for an exact quote - estimates are free.
