Toto Construction in San Martin, CA | Workshop Contractors
We provide independent Toto service across San Martin, CA, handling everything from a single Drake fill-valve rebuild to a full bathroom remodel where the Toto fixtures go in with the tile. For homeowners nearby, we also offer Morgan Hill Toto service. The thing that makes our Toto work here different is simple: we know that most San Martin homes run on private wells, and we scope every fixture swap against the existing pressure, mineral content, and drain setup before we touch a single bolt. If you’re planning a bathroom remodel in the 95046, call (844) 384-3361 and we’ll walk you through what your Toto fixtures actually need.
Workshop Contractors is a General Contractor – San Martin led by Noel Figueroa. We work on Toto fixtures every week in Santa Clara County’s rural southern valley, from original 1980s Drakes and Guinevere toilets in ranch homes to current Nexus and Aquia towers. We are an independent contractor, not authorized by Toto, and we say so plainly, because you should know exactly who’s working on your bathroom before the first valve comes apart.
Why San Martin Residents Choose Us for Toto Service
Toto builds a genuinely good fixture. The problem we see in San Martin is that most advice online was written for city homes on municipal water, and it falls apart on a well system with hard water mineral scale. We know the fill valves, flappers, and gaskets each Toto generation actually uses, and more importantly, we know which ones fail first in a San Martin ranch house with 30-year-old plumbing. That’s the difference between a repair that lasts and one that gives out in 14 months.
Noel Figueroa has been working around trades since he was a teenager in the Inland Empire. He learned framing, tile, and finish work the slow way, on job sites where a second look at the trim joint would tell you whether the contractor cared. Around our shop, the standard is the same one his grandfather set when he built the family’s house with his own hands: build it right the first time. The second time costs twice as much and nobody’s happy about it.
We source OEM-compatible Toto parts where it matters and vetted aftermarket parts where they perform identically. We tell you which is which, up front, before any work starts. That’s how we operate across San Martin service area, and it’s why homeowners with older Drakes and Washlets keep our number in their phones.

Common Toto Construction Problems We Solve in San Martin
- Fill and flush tower wear on Drake and Aquia toilets. San Martin’s hard well water leaves mineral scale that stiffens the Aquia’s dual-flush cartridge and shortens fill-valve life. We rebuild these with genuine Toto components and set the flush tower to work with your actual water chemistry, not the factory default.
- Wax-ring and flange failures in older ranch bathrooms. Slab movement and septic-side backflow quietly rot the subfloor before the toilet ever rocks. By the time you feel movement, there’s often hidden moisture damage underneath. We replace the flange, repair the damaged subfloor section, and reset the Toto fixture on a new ring before the floor ever gets a chance to fail further.
- Washlet and Neorest electronics in hot inland-valley summers. San Martin gets genuinely hot and dry, and the pump and control-board failures we see in Washlet seats often trace back to long dry-season heat plus scale-clogged nozzles from well-supplied bathrooms. If the seat blinks and won’t stop, don’t keep resetting it; the board may be cooking itself.
- Tank-to-bowl gasket seepage on one-piece Guinevere and Soirée units. These will weep when tank bolts loosen on a tilted floor. It happens a lot during a remodel tear-out, when the bathroom floor gets stripped and the old fixture gets bumped around. If you see water staining at the tank seam, that gasket is failing.
- Low flow at the Toto fill valve on well systems. The existing pressure tank and household pressure regulator will sometimes starve a modern Toto fixture. This is a San Martin well-house issue, not a Toto defect, but it looks like one. We test pressure at the fixture before replacing parts that don’t need replacing.
Toto Service in San Martin: What Local Conditions Mean for Your Equipment
Here’s what most contractor pages won’t tell you about San Martin: because this is unincorporated Santa Clara County, a bathroom or kitchen overhaul that touches framing, plumbing runs, or the septic connection needs county planning approval, not a city permit from Morgan Hill or Gilroy Toto service. On the many large lots along Llagas Road and the surrounding horse properties, we scope the Toto fixture swap against the existing well pressure and septic drain setup before any tile comes up. Skip that step and you end up with a beautiful new Toto toilet that runs slow because your pressure tank was sized for a 1980s ranch footprint, or worse, a new Walk-In shower that drains into a septic lateral that was never meant to handle it. We’ve been through this enough times to check the well pressure gauge and the septic cleanout location on the first visit.
We saw it on a mid-century ranch property off Llagas Road on a private well. Our crew tore out a green-tinted 1990s Drake whose fill valve had scaled solid and whose wax ring had seeped into the subfloor. We replaced the flange, rebuilt the water closet with a genuine Toto fill valve and flapper, and reset it on a new ring before the walk-in shower tile went down. In the same job we swapped an aging tub for a curbless shower and plumbed it for the homeowner’s existing Washlet, checking well pressure so the bidet seat would run correctly. That’s the kind of thing you learn working in San Martin long enough: the water and the permit path shape the fixture choices as much as the floor plan does.
Toto Models & Products We Service in San Martin
We service the fixture lines San Martin homes actually have. That includes the Toto Drake (CST743 series two-piece close-coupled toilet), the Aquia dual-flush (CST412/CST414), one-piece Guinevere and Soirée models, and Washlet bidet seats from the S300e and S550e up through the Neorest line. We fit genuine Toto fill valves, flappers, and flush-tower cartridges where the model calls for them, and we use vetted aftermarket gaskets, wax rings, and supply lines where they perform identically.
On a 20-year-old Drake, a rebuild is the right call. On a scale-battered Aquia with a cracked tank, we tell you straight that a replacement fixture makes more sense than chasing parts. We also handle full Toto installs as part of Toto sales & service work, including bathroom remodels and shower conversions where the fixture choice should be made early enough to affect the plumbing rough-in, not after the tile is set. Our relationship with Toto fixtures sits inside a broader material practice: we source and install, so the decision about a Toto versus a Kohler or Grohe fixture happens with the labor in mind, not in a showroom vacuum.

|---|---|
| Bathroom Remodel | $9,000 – $28,000 |
| Walk-In Shower Installation | $4,500 – $12,000 |

FAQs – Toto Construction in San Martin
Most of the time we can rebuild it with genuine Toto parts, and that’s usually the right call on a Drake that’s less than 20 years old and isn’t cracked or leaking at the tank seam. If the bowl is scarred, the tank has hairline cracking, or the flush tower housing is warped from heat and scale, a replacement fixture is the honest recommendation. Call (844) 384-3361 and we’ll tell you which one yours falls into.
Yes. San Martin is unincorporated Santa Clara County, so projects that touch framing, plumbing drain lines, or the septic connection go through county planning and the fire district, not a city hall. We pull those permits as part of the remodel scope so the Toto fixture and the shower pan both get signed off on the same inspection.
Usually yes, but the seat’s inlet pressure and mineral exposure matter more than on a municipal system. We check the pressure tank output and add a scale filter or regulator where the well chemistry would shorten the seat’s pump life. The seat itself isn’t the weak point; the water feeding it is.
That’s usually a failed wax ring leaking into the subfloor over time, which is common in older San Martin ranch bathrooms where the slab has shifted and the flange is low. The rocking toilet is the symptom, not the problem. We pull the fixture, replace the flange, repair or sister the damaged subfloor section, and reset the Guinevere on a new ring. Call (844) 384-3361 for an exact quote; estimates are free.
We do, and the Toto fixture choice should happen early in the remodel, because it affects the rough-in height, the water supply stub-out, and the floor flange location. We install Toto toilets, Washlet seats, and bidet-compatible lavs as part of full bathroom remodels, walk-in shower builds, and tub-to-shower conversions across San Martin.
