Toto Bathroom Remodeling: The Woodland Hills Owner’s Guide
Most Toto bathroom remodels in Woodland Hills run between $9,000 and $28,000 installed, depending on whether we’re swapping fixtures in an existing layout or rebuilding the room down to the studs. We stock Toto-compatible parts on the truck and can usually start a fixture-level remodel the same week you call. The way most homeowners find us is simple: a Toto toilet starts running or rocking at the base, a Toto washlet seat stops heating, or a shower valve from a Toto suite starts dripping, and suddenly a small annoyance becomes a bigger question about the rest of the room.
Before we get into models and symptoms, one thing worth saying clearly: Mason Remodeling Co Woodland Hills is an independent service provider. We install and remodel around Toto products, and we’re glad to do it, but we’re not a Toto dealer or affiliate. What we are is a Woodland Hills remodeler that has worked with Toto’s residential lines long enough to know which parts match which models, which aftermarket pieces hold up, and which ones don’t.
Which Toto Models This Applies To
Toto’s residential lines share a lot of DNA, but not everything swaps cleanly. The three series we see most in Woodland Hills homes are the Drake, the Ultramax, and the Nexus, plus wall-hung units from the Aquia line in newer condos and ADUs along the Ventura Boulevard corridor. Here’s what matters for parts matching.
The big compatibility gotcha is the flush valve. Toto uses a 3-inch valve on most Drake and Ultramax models, but older Drakes from the mid-2000s can have a 2-inch tower-style valve that accepts a different flapper entirely. If you swap a 3-inch flapper onto a 2-inch tower canister, it closes too fast and you get a half-flush that leaves paper behind. We check the stamp inside the tank before ordering anything.
The other common mix-up is the washlet mounting pattern. Toto C100 and C200 washlet seats use a different bolt spread than the S550e or S7 series, and retrofit plates exist but they’re ugly if installed wrong. For OEM versus aftermarket: Toto OEM parts fit correct the first time and carry the longest service life, but a quality aftermarket fill valve from Korky (the same manufacturer Toto uses on several OEM valves) performs just as well for about half the price. We tell homeowners the straight version of this trade-off at the estimate, not after the invoice.
When we start a Woodland Hills Toto remodel, we always confirm the model number. On toilets, it’s stamped inside the tank, usually above the waterline on the left wall. On washlets, it’s on a label under the seat hinge. On shower valves, it’s behind the trim plate. Ten seconds of checking saves us from ordering the wrong rough-in valve.

Signs Your Toto Bathroom Remodeling Is Failing
- The toilet runs for a few seconds every 20 to 30 minutes. This is usually a failing flapper or a fill valve that isn’t seating fully. In Woodland Hills, our harder water means mineral buildup on the valve seat accelerates this, and a toilet that runs is also a toilet that’s quietly adding to your LADWP bill.
- The bowl rocks or the wax ring has failed. A rocking Toto is almost always a flange problem underneath, not a toilet problem. If you catch a faint sewer smell near the base or see a water stain on the ceiling below a second-floor bath, the wax ring is done and we should pull and reset the toilet before the subfloor rots.
- The washlet seat no longer heats or the wand doesn’t extend. In our experience, hard-water scale in the Sacramento Valley doesn’t hit Woodland Hills the same way, but the valves inside washlet wands still seize over time. This is one of the few Toto parts I’ll tell you is rarely worth rebuilding, replacement is usually the better spend.
- The shower valve drips or you can’t hold a consistent temperature. Toto’s pressure-balance cartridges wear out, and when they do, a small drip becomes a constant one. Worse, a failing cartridge can let a sudden flush elsewhere in the house spike your shower temperature, which is a real safety concern if you have young kids or older adults in the home.
- The finish on the faucet or trim is pitting or clouding. Toto finishes are good, but the hard water in parts of Woodland Hills can be brutal on brushed nickel and chrome. Once the finish breaks down, cleaning products find their way under the plating. Replacement trim is often cheaper than a whole new valve body.

AfterReplacement Cost & What’s Included
Here’s the cost picture for Toto-focused bathroom work in Woodland Hills, in real numbers.
| Scope of Work | Typical Installed Range |
|---|---|
| Toilet replacement (Toto Drake or similar) | $500 – $1,200 |
| Washlet seat installation (electrical included) | $700 – $2,000 |
| Shower valve replacement with new Toto trim | $800 – $2,500 |
| Full small bathroom remodel with Toto fixtures | $5,000 – $12,000 |
| Full bathroom remodel, Toto throughout | $9,000 – $28,000 |
Every one of these numbers includes the parts, the labor, and the cleanup. The spread comes down to three things: whether walls need to open, whether plumbing needs to move, and whether the existing tile or flooring needs to come out to reach what’s behind it. You get a written price before any work starts, on every project, every time. That’s not a promotion. It’s how we’ve worked since 2004. And everything we install is covered by our 365-Day Done Right Promise: if the work isn’t right within a year of completion, we come back and make it right at no cost to you.
DIY or Call Us?
Some Toto maintenance is genuinely doable for a careful homeowner. Swapping a fill valve, replacing a flapper, or installing a new washlet seat on an existing rough-in are all afternoon jobs with basic tools. If you can identify the model and the part, you can handle those.
Where DIY goes wrong is when the problem is behind the wall or under the floor. A leaking shower valve is not a faucet washer situation. If the valve body behind the tile is leaking, you’re opening the wall to fix it, and that means waterproofing, tile, and grout all have to go back correctly or you’ll be chasing mold and water damage in a year. Same with a toilet that’s rocking: pulling the toilet is fine, but if the flange is cracked or set too low, the fix involves real plumbing work that shouldn’t be someone’s first-time project.

FAQs
Plan on 10 to 15 years of reliable service from a Toto toilet or shower valve in Woodland Hills before you’re spending real money on repairs, though washlet seats tend to go 7 to 10 years before the electronics or wand start misbehaving.

Yes, fill valves, flappers, cartridges, and some washlet components can be rebuilt, and we’ll do that when it makes sense, but we won’t rebuild a part that’s at the end of its service life just to save you a bill today and give you a bigger one next year. For an exact recommendation on your specific model, call (831) 290-6866.
