Toto Bathroom Remodeling: The San Jose Owner’s Guide
Toto bathroom remodeling in San Jose typically runs $10,620 – $33,040, and we stock Toto-compatible replacement parts on our trucks for most common failures. If your Toto toilet, bidet seat, or faucet has stopped working the way it should, we can usually identify the part, confirm it matches your model, and install it in a single visit. Most San Jose homeowners call us after weeks of ignoring a slow leak, a bidet seat that drips cold water, or a flush that needs two or three tries. The part has already failed, but the fix is usually more straightforward than the frustration leading up to it.
Which Toto Models This Applies To
We work on the full Toto line you’ll find in San Jose homes: Drake, Drake II, Ultramax, Promenade, Carlyle, Entrada, and Eco versions of each. Toto’s model numbers are stamped inside the tank, just below the waterline, and printed on the bowl under the rim. Write that down before you call anyone. It saves a second visit.
The compatibility gotcha with Toto is the flush valve and fill valve pairing. Toto uses a 3-inch flush valve on Drake and Ultramax, while some older Promenade and Carlyle models use a 2.5-inch opening. Aftermarket universal valves rarely seal tight on a 3-inch Toto opening unless they’re built specifically for it, and that’s where DIY repairs go sideways. We stock the OEM Toto parts plus quality aftermarket equivalents from Fluidmaster’s Toto-specific line. The OEM part carries the manufacturer warranty. The aftermarket equivalent often costs 20 – 30% less and performs identically when fitted correctly. We’ll give you both prices and let you choose.
For bidet seats, the Washlet series (C100 through S550e) has its own parts ecosystem: filter cartridges, inlet hoses, remote modules, and seat hinges that are not interchangeable across series generations. The C200 and C100 share some components, but the S500 and S550 use entirely different control units. Another San Jose specific: our hard water shortens Washlet filter life. The filter Toto rates for 12 months usually clogs in 8 – 10 months in neighborhoods like Almaden Valley and Evergreen, where mineral content runs high. We keep those filters on the truck.
A note: Penhallow Remodeling is an independent remodeling and service provider, not a Toto factory outlet. We install and service Toto products using genuine Toto parts or quality equivalents, but we are not affiliated with the manufacturer.

Signs Your Toto Bathroom Remodeling Is Failing
- Weak or incomplete flush, especially on the first try. The flapper or flush valve seal has worn or warped, and water is slipping past before the flush completes. On Toto’s G-Max and E-Max systems, this often shows up as a “ghost flush” where the tank refills on its own at night.
- Water pooling around the base of the toilet. This is almost always a failed wax ring or a cracked Toto bolt flange. In San Jose’s older slab homes around Willow Glen and Campbell, we see the flange rust through after decades of ground moisture. Ignoring this one rots your subfloor.
- Washlet seat runs cold or the remote won’t sync. The inlet filter has clogged with mineral deposits, or the seat’s control board has failed. Hard water in San Jose accelerates both. A cold Washlet mid-shower is the number one complaint we hear from homeowners in December and January.
- Constant hissing or trickling from the tank. The fill valve isn’t shutting off completely, which means the diaphragm or float seal has degraded. It’s a $20 part, but that slow trickle adds roughly $8 – $12 a month to a San Jose water bill.
- Rust stains or pitting around the faucet base and handles. Toto’s contemporary faucet lines, particularly the Lloyd and Soiree series, use ceramic disc cartridges that hold up well, but the mounting hardware can corrode in bathrooms with poor ventilation. Once the finish starts pitting, replacement is the only real fix.

AfterReplacement Cost & What’s Included
Here’s what we actually charge in San Jose for the most common Toto repairs and replacements:
| Service | Installed Price Range |
|---|---|
| Full bathroom remodel (Toto fixtures included) | $10,620 – $33,040 |
| Small bathroom remodel / powder room | $5,900 – $14,160 |
| Toto toilet replacement (parts + labor) | $710 – $1,890 |
| Washlet bidet seat installation | $530 – $1,420 |
| Flush valve + fill valve replacement | $235 – $530 |
| Bathroom vanity installation (with plumbing) | $945 – $3,540 |
The range depends on what we find when we open the wall or floor. A toilet swap in a bathroom with a compromised flange costs more because we repair the flange and replace the wax ring rather than layering a new toilet on a failing base. A full remodel price depends on tile footage, whether we’re moving plumbing, and whether the shower pan is pre-fabricated or we’re building a custom mortar bed. Every line item is written down before work starts. The number you sign is the number you pay.
DIY or Call Us?
You can safely check a few things before you call. Lift the tank lid and note the model number. Watch whether the flapper seats cleanly or wobbles. If your Washlet remote won’t pair, try a fresh set of batteries and unplug the seat for thirty seconds. Those are all safe diagnostics.
Where DIY goes wrong in San Jose is usually the water shutoff valve. Homes built before 1990 often have angle stops that have been frozen open for decades. When a homeowner cranks one to swap a fill valve, the valve can snap behind the wall and flood the bathroom. If your shutoff valve looks corroded or won’t turn easily, stop and call us. The same goes for any toilet with movement at the base. That’s not a loose bolt, it’s a failing flange or subfloor, and tightening it without fixing the substrate just cracks the porcelain. Give me the real problem and I’ll give you the real number. Call (669) 274-2362 and we’ll schedule a time to look.
FAQs
A properly maintained Toto toilet lasts 20 – 30 years, but the internal components, flapper, fill valve, flush seal, typically need replacement every 4 – 6 years, sooner in San Jose’s hard water areas. Washlet seats average 7 – 10 years before the control board or heating element fails. If yours is over 8 years old and needs a major component, replacement often makes more financial sense than repair.
Sometimes, but it depends on the part. A fill valve with a bad diaphragm can be rebuilt with a $12 seal kit. A Washlet control board cannot be economically repaired, and neither can a cracked toilet bowl. We’ll tell you straight which side of the line your part falls on before we order anything, and we’ll show you the repair price versus the replacement price side by side.
Most single-part replacements, a fill valve, a flapper, a Washlet filter, a faucet cartridge, take 45 – 90 minutes once we’re in the door. A full toilet swap with flange repair typically takes 2 – 3 hours. A complete Toto bathroom remodel runs 3 – 6 weeks depending on scope. We’ll give you a written timeline before work starts, and we’ll tell you if that timeline shifts and why.
We keep common Toto flappers, fill valves, flush seals, Washlet filters, inlet hoses, and seat hinges on the truck when we service San Jose. Special-order items, a specific color-matched tank lid, a discontinued Washlet remote, typically arrive within 5 – 10 business days. You’ll know before we leave whether your part is in hand or on order, and we won’t charge a second trip fee if we have to return. That’s covered in the written guarantee.
If your Toto fixture is failing, don’t wait for the slow leak to become a subfloor replacement. Call (669) 274-2362 and we’ll put a real person on the line, day or night. We’ll schedule a visit, diagnose the part, and give you a written price before any work starts. Penhallow Remodeling San Jose is part of the Kingswell family of companies, and every job carries the 365-Day Done Right Promise: if it’s not right, we make it right, in writing, for a full year.
