Toto Kitchen Remodeling: The Los Angeles Owner’s Guide
If you’ve got a Toto kitchen fixture that’s failing, here’s the straight answer: Mason Remodeling stocks and installs Toto-compatible kitchen components across Los Angeles, with full kitchen remodels running $16,520 – $53,100 depending on scope. Most Toto-specific part replacements (a pull-down faucet head, a soap dispenser cartridge, a sink basket, a pot filler valve) run between $145 and $610 installed. We can typically get a Toto-compatible part matched and swapped within 48 hours of your call, often faster if it’s a common item on our trucks.
Here’s how Los Angeles homeowners usually find us: a Toto touchless faucet stops responding to the sensor, a pull-down spray head starts leaking at the pivot joint, or a kitchen sink flange cracks and drips into the cabinet below. They pull up the Toto manual, realize the part number is buried in fine print, and start hunting. That’s the exact moment this page is for.
Which Toto Models This Applies To
The Toto kitchen line in the U.S. centers on the Kes, Aimes, and Maris faucet series, plus the BX and SX sink lines and the Waza drop-in sinks. The compatibility gotcha most owners hit: Toto uses a G1/2 thread on many faucet supply lines, which is not the same as the standard NPT thread on most American fixtures. If you buy a generic supply line from a big-box store, it threads on loose and leaks within a week. We keep Toto-pitch adapters on the trucks for exactly this reason.
Identifying your model is simple: look under the sink for a small white tag on the faucet body or the flex hose. The model number starts with a letter (K for Kes, A for Aimes, M for Maris) followed by four digits. If the tag is gone, measure the spray head diameter: Kes is 1.25 inches, Aimes is 1.5 inches. When it comes to replacing parts, OEM Toto parts fit perfectly every time, but they’re slower to source and pricier. Quality aftermarket equivalents from Delta-compatible manufacturers often work, but only if the thread pitch and cartridge match exactly. For Toto touchless faucets, we recommend OEM sensors and solenoids every time. The aftermarket versions are inconsistent, and a misaligned sensor is the most common reason a “repaired” touchless faucet quits again in six months.
Mason Remodeling is an independent service provider, not affiliated with Toto. We specify their fixtures because they hold up in Los Angeles hard water better than most, but we’re not a Toto warranty station.
Styles & brands we work with
Signs Your Toto Kitchen Remodeling Is Failing
- The faucet leaks from the base of the spout when you turn it on. That’s almost always a worn O-ring or cartridge seal inside the faucet body. Left alone, water works its way under the base plate and into the countertop edge, warping the particleboard under the laminate or stone.
- The pull-down spray head sags or won’t retract. The internal weight or spring inside the hose has failed, or the hose is snagged on the under-sink plumbing. In Los Angeles homes with rigid copper supply lines, we see this more often because the hose has less room to move.
- The touchless sensor works intermittently or only when your hand is within an inch of it. Mineral buildup from hard water coats the infrared eye. Descaling sometimes helps, but a sensor that’s been coated for more than a year usually has corrosion behind the lens and needs replacement.
- Water pressure at the sink drops, but the rest of the house is fine. The aerator is clogged, or the Toto cartridge screen is full of sediment. The San Fernando Valley supply mix tends to carry more silt after heavy rain, so we see this pattern in Encino, Van Nuys, and Northridge regularly.
- The sink basket strainer won’t seal, even after you tighten it. The rubber gasket underneath has dried out and cracked. Sun and heat in Los Angeles kitchens accelerate rubber breakdown, especially on south-facing setups where the sink cabinet gets afternoon sun.

AfterReplacement Cost & What’s Included
A full Toto kitchen remodel in Los Angeles runs $16,520 – $53,100. Most of that range comes down to scope: a $16,520 project is a cabinet reface, new Toto sink and faucet, and laminate counters. A $53,100 project is a full gut-out with KraftMaid cabinetry, Toto fixtures, and Cambria or Silestone surfaces.
For a standalone Toto parts replacement, here’s what the numbers look like in Los Angeles:
- Pull-down spray head replacement: $95 – $185 installed. We check the hose and weight at the same time. No extra charge if they’re fine.
- Cartridge replacement (Kes, Aimes, Maris): $165 – $310 installed. The cartridge itself is $60 – $120 depending on the series. Labor is the rest. We shut off the water, pull the handle, swap the cartridge, and test for drips before we leave.
- Touchless sensor replacement: $210 – $410 installed. OEM Toto sensors run higher, and we won’t install aftermarket on touchless units. It’s the one place we insist on the Toto part.
- Sink basket strainer and gasket: $85 – $155 installed. Includes removing the old plumber’s putty, cleaning the flange seat, and new putty. Half the Los Angeles sinks we open have the old putty rock-hard and cracked.
Every job gets a written price before we start. No verbal estimates that grow on the final bill. The work is covered for 365 days from completion, with a free return visit if something fails. That’s the Mason Remodeling standard, stated plainly.
DIY or Call Us?
The honest split: if your Toto sink basket is slow to drain, you can remove the strainer, clean the seat, and replace the putty yourself in about an hour. That’s a basic homeowner task. If your faucet leaks at the base, the cartridge swap involves shutting off the angle stops (which in older Los Angeles homes are often seized and break when forced), pulling a retaining clip without scratching the finish, and getting the new cartridge seated square without damaging the O-rings. If you strip a Toto retaining nut or crack the faucet body, you’re buying a full faucet, not a $165 cartridge.

FAQs
A Toto kitchen faucet should last 10 – 15 years in Los Angeles, but hard water minerals will typically shorten the cartridge life to 7 – 8 years before you notice stiffness or a drip at the base. Residential water in the LA basin averages 100 – 180 parts per million of dissolved minerals, enough to coat internal seals within a decade. Call (803) 680-2547 for a free assessment if yours is failing early.
Yes, in most cases. The three most common failures on Toto touchless faucets are the sensor, the solenoid valve, and the battery pack, and each of those is a replaceable part. We replace the failed component rather than the whole faucet about 80% of the time. The exception is when the faucet body itself has corroded around the sensor mount, which happens in older installations near the ocean in places like Santa Monica and Playa del Rey. Call (803) 680-2547 for an exact quote after we see the faucet.
Most Toto parts replacements take 45 minutes to 2 hours on site. A spray head swap is under an hour. A cartridge replacement runs 60 – 90 minutes. A touchless sensor replacement with a solenoid can hit 2 hours if we’re descaling the faucet body at the same time. We quote the time before we start, and the price doesn’t change.
We stock the most common Toto items on our Los Angeles trucks: Kes and Aimes spray heads, G1/2-to-NPT supply line adapters, cartridges for the Kes and Maris series, sink strainer assemblies, and Toto-specific aerators. Specialty items like touchless sensors and solenoids are typically at our supplier within one business day. We can usually quote you the exact part price while you’re on the phone.
