Why Torrance Homeowners Choose Toto Construction
Toto repair in Torrance is what homeowners call us for when a Drake toilet starts ghost flushing at 3 a.m. or an Ultramax II develops a hairline crack near the floor bolts. We’re Mason Remodeling Co Torrance, and we’ve installed, repaired, and remodeled around Toto fixtures in hundreds of Torrance homes, from 1950s Rancho Del Rey bungalows to newer South Bay builds. We are not affiliated with or authorized by Toto. That’s actually a good thing for you: we recommend the fix that makes sense for your bathroom and your budget, not the one that protects a manufacturer’s warranty margin. Call (424) 337-6939 for a free estimate on any Toto repair or full bathroom remodel.
Why Trust Mason Remodeling Co Torrance for Your Toto Construction?
Our crews work on Toto fixtures weekly, not occasionally. That repetition means we know which models hold up in Torrance’s hard water and which need early intervention before a small leak turns into a subfloor tear-out. Isaac Pruett, our owner, studied construction technology at Los Angeles Trade-Technical College and spent nearly two decades moving through every phase of residential remodeling before leading our Torrance team. He’s the kind of contractor who reads a job site fast and tells you the truth before he picks up a tool. When you book Toto work with us, you get a written price before any work begins, every crew member’s name and photo before they arrive, and our 365-Day Done Right Promise: if something isn’t right within a year, we return and fix it at no charge.
- OEM-first parts. We use genuine Toto fill valves, flappers, and gaskets on Drake and Ultramax models because aftermarket parts often don’t match the seal and flow specs. If a part is discontinued, we’ll tell you honestly and recommend a quality aftermarket option or a new fixture, whichever costs less in the long run.
- Hard water experience. Torrance water leaves mineral deposits in Washlet internal lines and causes fill valves to chatter. We descale rather than replace when it’s safe and cost-effective.
- Slab floor realities. Many Torrance homes built in the 1950s and 1960s have slightly uneven slab floors. Toto skirted bowls like the Ultramax II can hairline-crack at the mounting bolts if installed without proper shimming. We shim and level every bowl before tightening anything.
- Written guarantee on every job. You’ll get the terms in writing: what’s covered, what’s excluded, and for how long. No verbal promises, no “we’ll figure it out later.”

Common Toto Construction Problems We Fix in Torrance
Here are the Toto issues we see most often in Torrance bathrooms. If you’re dealing with one of these, it’s worth a call before water finds its way somewhere expensive.
- Toto Drake slow tank-to-bowl gasket leak. After 8 to 12 years, the gasket between tank and bowl on a Drake two-piece compresses into a hard, cracked ring. The toilet ghost flushes, water seeps down the back of the bowl, and in older Torrance bathrooms with original wood subfloors, that moisture sits against framing and slowly rots it. We replace the gasket and bolt kit with genuine OEM parts and level the bowl properly on your existing floor.
- Toto Ultramax II hairline cracks near the mounting bolts. The skirted bowl on an Ultramax II is beautiful, but it doesn’t forgive uneven floors. On the 1960s slab floors common in South Torrance, a slight rise under one side puts pressure on the bolt flange during installation. Over time, a hairline crack forms. If caught early, we can sometimes reinforce and reseal. More often, the bowl needs replacement, and we’ll shim and level the new one so it doesn’t happen again.
- Toto Washlet C2 or C5 losing heated seat or warm water. Torrance hard water deposits minerals inside the Washlet’s internal lines and heating chamber. Symptoms are a seat that won’t warm, or warm water that fades after a few seconds. We descale the internal lines and heating element. That fixes most units without removing the seat, let alone replacing it.
- Toto Promenade pedestal sinks pulling away from the wall. In older Torrance homes, these sinks were often lagged into plaster or even drywall without proper backing. Over decades, the weight of the pedestal works the bracket loose, and the sink starts to lean. We open the wall, add blocking behind the tile, and re-secure the bracket so the sink sits flush and solid.
- Toto fill valve chatter and slow refill. If your Toto toilet sounds like a foghorn when the tank refills, the fill valve is likely crusted with mineral scale from Torrance’s water. A new OEM fill valve is a quick fix, and we’ll check the flapper and flush valve while we’re in there, since they usually wear at the same rate.
Last month our crew pulled a leaking Toto Drake from a 1963 bathroom near Torrance High and found the tank-to-bowl gasket had compressed into a hard, cracked ring. We installed a new OEM gasket and bolt kit, leveled the bowl with shims on the original mosaic tile floor, and then replaced the owner’s worn Washlet C2 remote sensor at the same visit. The toilet stopped ghost flushing that day, and the subfloor dried out without any tile tear-out.
Toto Parts & Our Repair-vs-Replace Approach
We stock the Toto parts that fail most often in Torrance, including genuine OEM fill valves, flappers, tank-to-bowl gaskets, and bolt kits for Drake and Ultramax models locally. That means most toilet repairs happen in a single visit. For discontinued trim or cosmetic pieces, we recommend quality aftermarket brass or ceramic options, but we’ll be straight with you when chasing parts on a 20-year-old fixture costs more than replacing it with a new Toto. Our rule is simple: if a repair costs more than half the price of a new fixture and the old one’s already showing age, we tell you. No warranty pressure, no upsell. You decide, and we’ll do either job with the same care. Call (424) 337-6939 for an honest assessment, free of charge.
Our Toto Service Process – Step by Step
- 1
Diagnosis. We inspect the fixture, identify the specific Toto model and failure point, and check for hidden damage – especially water staining on the subfloor around a Drake or Ultramax II. You’ll know what we found and what it costs before we touch a tool.
- 2
Repair or installation. We use OEM Toto parts whenever available. For Skirted bowls, we shim and level on your specific floor before final tightening. For Washlets, we descale internal lines and test water temperature and seat heat before closing the unit.
- 3
Testing. We run multiple flush cycles, check for leaks at the tank bolts and supply line, and verify the bowl sits level with no rocking. For Washlets, we test every function: seat heat, water temp, pressure, and remote response.
- 4
Warranty and follow-up. You receive our written guarantee with clearly stated terms. We cover our work for 365 days from the completion date, and if anything we installed or repaired fails within that year, we return and fix it at no charge.

AfterToto Products We Service & Install in Torrance
As your General Contractor, we work on the complete Toto line that shows up in Torrance homes, including the Toto Drake two-piece toilet, Toto Ultramax II one-piece toilet, Toto Washlet C2 and C5 bidet seats, and the Toto Promenade pedestal sink. We also service older and discontinued Toto models still found in 1950s and 1960s bathrooms across Torrance. Beyond fixtures, we handle the larger construction work around them: full bathroom remodels, tub-to-shower conversions, and walk-in shower installations with Toto fixtures specified from day one. We stock common OEM replacement parts locally for fast turnaround on Drake and Ultramax models.
We Also Service These Brands
While Toto is a brand we know deeply, Mason Remodeling Co Torrance works across the full spectrum of quality kitchen and bath lines. We’re equally comfortable specifying KraftMaid cabinetry, Cambria or Silestone countertops, and Kohler fixtures in a full remodel. That multi-brand experience matters, because a bathroom remodel is never just one product – it’s a system, and we know how Toto works alongside every other component in the room.
FAQs – Toto Construction Service in Torrance
Why does my Toto Drake keep ghost flushing at night even though no one uses the bathroom?
Ghost flushing on a Toto Drake almost always means the tank-to-bowl gasket has failed, allowing water to seep from the tank into the bowl until the fill valve kicks on to refill it. In Torrance, we see this most often on Drakes that are 8 to 12 years old. The fix is a new OEM gasket and bolt kit, and we level the bowl at the same time so the new gasket seats evenly. Call (424) 337-6939 for an exact quote – estimates are free.
Can you install a Toto Washlet bidet seat on my existing toilet if there is no outlet nearby?
Yes. The most common solution we use in Torrance is running a new GFCI-protected outlet from an existing bathroom circuit, installed to current electrical code. We handle the electrical work as part of the installation, so you don’t need to coordinate a separate electrician. We also descale the Washlet’s internal lines during installation if you have hard water, which gets the seat starting clean. Call (424) 337-6939 to schedule an assessment at no cost.
My Toto Ultramax II has a hairline crack near the floor bolts. Is it safe to repair or do I need a new toilet?
A hairline crack near the mounting bolts on an Ultramax II is a structural issue, not a cosmetic one. Repairing it with adhesive or epoxy is unreliable because the crack sits at the point where the bowl’s weight bears down on the bolts. The crack will grow. The honest answer is replacement – and when we install the new bowl, we shim and level it carefully on your specific floor to keep the same failure from repeating. Call (424) 337-6939 for a replacement quote with genuine Toto parts.
What is the best Toto toilet for a small powder room in an old Torrance home with a rough-in that is not exactly 12 inches?
In older Torrance homes, we regularly find rough-ins that measure 10 or 14 inches instead of the standard 12. For tight powder rooms, we recommend a compact round-front Toto model that works with your specific rough-in dimension, and we’ll confirm the measurement before ordering anything. Guessing on rough-in is how you end up with a toilet that doesn’t fit or a tank that sits an inch off the wall. We measure, then recommend, then install. Call (424) 337-6939 and we’ll check your powder room.
During a bathroom remodel, should we keep our existing Toto toilet or replace it with a newer model?
That depends on the toilet’s age and condition. If it’s a Drake or Ultramax II less than 8 years old with no leaks, cracks, or mineral buildup, keeping it is reasonable and we’ll work around it. If it’s approaching 12 to 15 years old, we usually recommend replacing it during the remodel, because the labor cost of pulling and resetting a toilet mid-remodel is lower than doing it separately later, and new Toto models use less water. We’ll give you a straight recommendation either way, with prices for both paths.
How much does Toto construction cost in Torrance?
Toto service in Torrance typically runs between $450 and $950 for a full Drake toilet replacement with OEM parts and labor. A Washlet C2 or C5 bidet seat installation, including a hard water descale, falls between $350 and $700. A full bathroom remodel with Toto fixtures and tile ranges from $9,000 to $28,000 depending on scope. Here are the current market ranges:
| Service | Price Range (Torrance) |
|---|---|
| Toto Drake toilet replacement (OEM parts + labor) | $450 – $950 |
| Toto Washlet C2/C5 bidet seat installation (descale included) | $350 – $700 |
