Toto Construction in Los Gatos, CA | Rowan Construction Group Campbell
We provide independent Toto service across Los Gatos, from Washlet bidet seats in hillside homes to full Bathroom Remodeling in Los Gatos with Neorest integrated toilets in the historic downtown core. The one thing that makes our Toto work here different is that we build around Los Gatos’ dual permitting reality - CAL FIRE ignition-resistant standards on the slopes, Historic Preservation Committee review on the flatlands - so your fixture installation doesn’t stall because a contractor missed a required geotechnical report or design review. Call (831) 704-1211 to schedule your free estimate.
Why Los Gatos Residents Choose Us for Toto Service
We’ve installed and serviced Toto fixtures in Los Gatos since before the Washlet S550e was the flagship model. Our crews know the difference between a Drake II flush valve and a Neorest dual-cyclone system, and we stock genuine Toto OEM parts - fill valves, flappers, wax rings, control boards - so we’re not ordering overnight while your bathroom sits torn apart.
Grant Rowan, our owner, trained at Santa Monica College’s Construction Technology program and learned to read blueprints, calculate load paths, and pull permits correctly the first time. That discipline matters in Los Gatos more than most places. He’s run gut-renovations near Campbell’s Pruneyard Shopping Center that required careful inspector coordination, and he brought that same rigor to Los Gatos, where a missed Hillside Development Permit can add months to a bathroom remodel. We don’t guess at paperwork. We document it.
We’re an independent Toto service provider, not manufacturer-authorized. That means we work on what’s actually in your home - discontinued Eco Ultramax units, imported Neorest models, custom configurations - without corporate restrictions on which parts we can use. Under Clause 1 of the Haven Standard, you get a written price before any work starts. Under the 365-Day Done Right Promise, if it’s not done right, we make it right. Measure twice, document once, build it right.
Common Toto Construction Problems We Solve in Los Gatos

- Washlet control board failure from power instability. Los Gatos hillside homes, especially west-facing properties off Highway 9 and Black Road, see frequent PG&E outages and voltage fluctuation. Older wiring in 1950s ranch homes can’t handle the surge when power returns, frying the sensitive electronics in Toto Washlet S550e and C5 units. We install dedicated GFCI circuits and surge-protected outlets as part of repair.
- Mineral scaling in fill valves from hard water. Los Gatos municipal water runs notably hard, with calcium and magnesium deposits that clog Toto’s precision fill mechanisms in Drake and Ultramax toilets. We see this weekly in homes near the flatlands and the hills alike. Our stock includes genuine Toto fill valves, and we’ll show you the scale buildup on the old part before we replace it.
- Wax ring failure from seismic slab movement. The Loma Prieta epicenter sits in the Santa Cruz Mountains just southwest of town. Cripple-wall foundations and unreinforced slabs in pre-1989 homes shift microscopically with every minor tremor. That movement cracks wax rings under Toto Drake and Ultramax toilets, creating hidden leaks that rot subfloors. We use extra-thick reinforced wax rings and inspect the flange for level before seating any toilet.
- Bidet pump corrosion in seasonal or fog-exposed homes. West- and north-facing hillside properties in Los Gatos sit in persistent marine fog off the Santa Cruz Mountains. Toto Washlet internal pumps and ceramic heaters corrode when moisture intrudes during extended non-use, common in vacation homes or guest baths. We test pump draw and heating element resistance, and we’ll tell you honestly if the repair exceeds replacement value.
- Neorest installation complications in historic downtown properties. The Town of Los Gatos Historic Preservation Committee requires design review for any exterior alteration to pre-1940s structures, and interior work often triggers electrical and plumbing inspections that flatland contractors don’t anticipate. We recently completed a master bath remodel in the historic downtown area where the homeowner wanted a Toto Neorest integrated toilet and a Toto Washlet in the guest bath. During demolition, we found the original 1920s cast iron drain lines were misaligned with the new fixture layout, so we re-routed the drain and installed new Toto OEM wax rings and supply lines. The Neorest’s electronic bidet required a dedicated GFCI circuit, which we added after discovering the existing wiring was ungrounded - a common issue in pre-1940s Los Gatos homes.

AfterToto Service in Los Gatos: What Local Conditions Mean for Your Equipment
Los Gatos occupies a rare regulatory position in Santa Clara County. On the same street in some neighborhoods, you can cross from a Wildland-Urban Interface zone requiring CAL FIRE-mandated ignition-resistant construction - Type A roofing, ember-resistant venting, non-combustible siding - into the historic downtown district where the Town’s Historic Preservation Committee controls even paint color and window proportion. For Toto owners, this dual burden surfaces most painfully in Kitchen Remodeling - Los Gatos and bathroom projects on hillside lots above roughly 500 feet elevation. Any building permit on those properties automatically triggers the Town’s Hillside Development Standards, requiring a geotechnical report, a visual impact study, and often a separate Hillside Development Permit. We’ve seen contractors arrive from San Jose flatland jobs, pull a standard building permit, and discover two months later that their Toto fixture delivery date means nothing because the hillside review hasn’t even started. That 2-4 month delay is specific to Los Gatos. We build it into our project timelines from the first site visit, so your Neorest or Washlet installation isn’t sitting in a warehouse while paperwork moves.
Toto Models & Products We Service in Los Gatos

We work across the full Toto residential line: Toto sales & service includes Washlet bidet seats (S550e, C5, and earlier generations), Drake and Ultramax gravity-flush toilets, the Neorest integrated toilet-bidet systems with dual-flush actuation, and the EcoPower and Eco Ultramax water-saving models. Our Campbell warehouse stocks OEM fill valves, flappers, wax rings, and Washlet control boards for same-day or next-day Los Gatos turnaround. For discontinued models, we source high-quality aftermarket parts or advise honest replacement when repair economics don’t work. Toto vitreous china outlasts most electronics - if the bowl and tank are sound, we’ll fix it rather than sell you a whole new unit.

FAQs - Toto Construction in Los Gatos
Yes. We install and repair Toto Washlet S550e, C5, and earlier models, plus Neorest integrated toilet-bidet systems across Los Gatos. We stock OEM control boards, heating elements, and spray wands for fast repair. Call (831) 704-1211 to schedule - estimates are free.
Hard water mineral buildup is the most common cause in Los Gatos. Calcium and magnesium deposits prevent Toto fill valves from seating fully, letting water leak continuously into the bowl. We replace with genuine Toto fill valves and can show you the scale damage on the removed part. Call (831) 704-1211 for an exact quote - estimates are free.
Yes, we coordinate with the Town of Los Gatos Historic Preservation Committee for any required design review on pre-1940s structures, and we handle permit applications that include both standard building and hillside development requirements where applicable. Your Toto fixture selection stays flexible - we document the install spec in writing before demolition starts. Call (831) 704-1211 to review your property’s specific requirements.
We prioritize urgent calls for active leaks, complete stoppages, and backed-up drains that risk water damage.

For non-emergency service, we typically schedule within 48 hours. Call (831) 704-1211 - we’ll assess urgency and slot you accordingly.
Toto vitreous china bowls and tanks last decades; the failure points are almost always replaceable components - fill valves, flappers, wax rings, or on Washlet models, electronic boards. We repair when the ceramic is sound and replacement when the unit is cracked, obsolete, or repair costs exceed 60% of replacement. We give you both numbers in writing. Call (831) 704-1211 for an exact quote - estimates are free.
