Toto Construction in Tiburon, CA | Toolbox Contractors
We’re Toolbox Contractors, and we provide independent Toto fixture installation, repair, and remodeling service across Tiburon. The thing that separates our Toto work here from a flat-lot job in Corte Madera is simple: we plan every bathroom project around hillside foundation movement, salt-air corrosion, and Town of Tiburon permitting. We are not authorized or affiliated with Toto, but we’ve fitted and serviced their fixtures on the Tiburon Peninsula long enough to know exactly how they hold up here. Call (855) 382-3257 for a free estimate.
Why Tiburon Residents Choose Us for Toto Service
Tiburon bathrooms aren’t like bathrooms in the flats. They sit on slopes. They breathe salt fog. They sit in homes where a second-story addition can trigger design review before a permit gets pulled. We know Toto fixtures, but we also know what those fixtures are up against on these hillsides. Our crew has re-plumbed Toto Drakes, reset one-pieces on shifting subfloors, and diagnosed washlet electronics that have been eating marine air for a decade.
Norm Castellano, who runs our crew, came up through the construction technology program at San Bernardino Valley College and spent twenty years as a General Contractor – Tiburon homes need, wrestling with exactly the kind of foundation and framing quirks that show up here. He’s the guy you call when a previous contractor left a mess that needs to be untangled before real work can start.
We stock genuine Toto OEM parts for the most common failures we see on the peninsula, which means we’re not waiting a week for a fill valve when your Drake has been running all night. And when a fixture needs full replacement, we handle the whole scope: the plumbing, the subfloor, the permit, the tile. One contractor. Every phase.

Common Toto Construction Problems We Solve in Tiburon
- Washlet seats and Neorest control boards corroding from salt fog. Marine air off Richardson Bay works its way through bathroom venting and exterior penetrations. We see intermittent seat-heat failures, bidet-pump faults, and boards that throw codes only when the fog sits thick for a week. These are salt-in-the-electronics problems, not user-error problems.
- Weak flushing and running tanks on Drake and Ultramax models after winter storms. When sediment gets churned into the supply lines during heavy rain, the 1.28 gpf flush towers and fill valves scale up and stick. The toilet still looks fine; it just flushes like it’s on its last leg.
- Rocking one-piece toilets and seeping wax rings on hillside slabs. Seasonal soil creep on Tiburon slopes tilts bathroom subfloors by fractions of an inch. That’s enough to break a wax ring seal. The first sign is usually a faint sewer smell or a toilet that shifts when you sit.
- Clogged Washlet inlet screens on older galvanized supply lines. Old Tiburon and the Belvedere-Tiburon flats still have plenty of pre-1970s galvanized plumbing. Mineral scale and rust flake off those pipes and pack the inlet screens, which drops spray pressure and triggers error codes on the Washlet.
- Electronic fixtures on circuits that were never meant for them. Neorest and high-end Washlet models pull real current. We routinely find them on shared circuits with no GFCI protection that should have been dedicated. On a hillside home that gets coastal moisture, that’s both a performance issue and a real safety concern.
Toto Service in Tiburon: What Local Conditions Mean for Your Equipment
Here’s the thing about Toto in Chinatown and Tiburon that a generic plumbing page will never tell you. On the steep streets off Lyford Drive and around Bel Aire, staging material for a bathroom remodel often means coordinating with neighbors and the Town of Tiburon. You can’t just park a truck full of tile and a crane on a 30% grade. And because so many of these homes sit on engineered foundations, we check subfloor level and framing before we ever set a Toto one-piece. Slope movement in Tiburon shows up first as a rocking toilet and a failed wax ring, long before it shows up as a crack in the drywall. That’s the check a flat-lot contractor skips. That’s the check that keeps your Drake from seeping sewer gas into a $4 million hillside house.
Toto Models & Products We Service in Tiburon
We service the full Toto residential line, with the most frequent calls tied to a few specific models. The Toto Drake is the workhorse of Tiburon bathrooms; we see more of those than anything else, usually with flush tower and fill valve issues. The Ultramax II comes in close behind, especially in remodeled hillside homes where the one-piece design was chosen to fit tighter rough-ins. Toto Neorest units are the luxury end; when those come in with error codes, it’s almost always a control board or a supply-line issue. And Toto Washlet seats, which go into nearly every remodeled Tiburon master bath and are the single most common electronic fixture we diagnose.
Our parts approach is straightforward: genuine Toto OEM fill valves, flush towers, wax rings, and electronic control boards for anything warranty-sensitive or electronic. We use high-quality aftermarket parts only for wear items where they meet or exceed OEM spec. Sound bowl and seat but a failed valve? We repair. Cracked porcelain or an obsolete electronic unit? We’ll tell you to replace it rather than chase parts that cost more than a new fixture. Tell me what you’ve got and I’ll tell you what it actually needs.

AfterToto Service Pricing in Tiburon
Home Remodeling – Tiburon costs run higher than the East Bay average, driven by permit fees, slope engineering, and the labor required to work on tight hillside sites. Here’s what Toto-related work typically runs in this market:
| Service | Price Range |
|---|---|
| Full Bathroom Remodeling | $9,000 – $28,000 |

| Walk-In Shower Installation | $4,500 – $12,000 |
| Bathroom Vanity Installation | $800 – $3,000 |
What drives the final number depends on scope: whether we’re resetting one fixture or gutting the room down to studs, whether the subfloor needs leveling, whether the supply lines are original galvanized. Every estimate includes a written line-item breakdown, and we’ll tell you before we start if we think a repair is smarter than a replacement. Call (855) 382-3257 for an exact quote.

FAQs – Toto Construction in Tiburon
Yes, and noticeably so. The constant salt-laden moisture off Richardson Bay and the San Francisco Bay shoreline corrodes control boards and connector terminals faster than the dry air in places like Novato or San Rafael. We see Washlet seats in Tiburon with intermittent faults that are directly traceable to salt corrosion on the board. Call (855) 382-3257 and we’ll diagnose the board before replacing the whole seat.
If the swap is like-for-like and you’re not opening walls or moving plumbing, a permit usually isn’t required. But if the remodel involves moving the drain line, altering the subfloor, or tying into new supply lines, the Town of Tiburon building department will want it permitted. We handle the permit ourselves on any job with a scope change, and inspections are coordinated by our crew, not by the homeowner. Call (855) 382-3257 and we’ll tell you straight what needs a permit and what doesn’t.
Winter storm runoff churns sediment into supply lines, and that sediment scales the flush tower and fill valve in a Drake’s 1.28 gpf system. The result is a weak flush and a tank that keeps running. It’s typically fixed the same visit with a genuine Toto OEM fill valve and a flush tower cleanout. Call (855) 382-3257 for an exact quote.
Depends on the age of the unit and which board is failing. If the control board is current and available as a Toto OEM part, repair usually makes sense. If the board is obsolete or the unit is more than a decade old and corrosion has spread, replacement is often cheaper than chasing parts. We’ll give you a straight answer before you spend anything. Call (855) 382-3257 and we’ll diagnose it.
Yes, but with a caveat. We always check the inlet screens and supply-line condition first. Galvanized lines shed rust and scale that clog Washlet inlet filters and drop spray pressure. If the lines are too far gone, we’ll quote re-piping the supply as part of the job rather than install a seat that’ll fail in six months. Call (855) 382-3257 for an evaluation.
