Toto Construction in Sun City, CA | San Mateo Construction
We provide independent Toto service across Sun City, CA — plus Toto in Quail Valley, Romoland, Good Hope, and Perris — covering installation, repair, re-setting, and full bathroom retrofits built around Toto fixtures. The thing that makes our Toto work here different is simple: we know how a Drake, Ultramax, or Neorest behaves on original Del Webb slab plumbing with hard inland water and decades of settlement. We’re not manufacturer-authorized, which means we’ll tell you straight when the flange is the real problem and the toilet itself is fine. Call (855) 901-7266 for a free estimate.
Why Sun City Residents Choose Us for Toto Service
We’ve pulled, re-set, and re-plumbed Toto fixtures in Sun City’s 1960s-80s ranch homes long enough to know the toilets aren’t usually the failure point. The slab is. The original wax seal is. The mineral-clogged fill valve is. That’s the difference between a contractor who sells toilets and one who understands how they sit on a 60-year-old concrete floor.
Noel Carrington, our owner, grew up learning construction the hands-on way – weekends pouring concrete footings with his father, then formal training in construction technology and three decades of residential work. He built San Mateo Construction around the idea that one contractor should know the whole house, from roofline to foundation. Tell me what you actually need, and we’ll figure out the right way to build it. That’s how we approach every Toto job in Sun City, and the same goes for our Romoland Toto service.
We stock genuine Toto OEM fill valves, flappers, wax seals, and Unifit adapters for fast turnaround on the models Sun City homeowners actually own. For Toto sales & service, we cover everything from a running Drake to a full Neorest retro-fit with HOA coordination.

Common Toto Construction Problems We Solve in Sun City
- Running Toto Drake toilets. Sun City’s water is hard – mineral scale builds up on fill valves and flappers faster than coastal cities. A Drake that “runs” or won’t seal is usually a mineral-fouled valve, not a bad toilet. We replace the OEM parts and the tank stops wasting water.
- Wax-seal failures and cracked closet flanges. The original Del Webb homes were built on slab foundations that have settled and baked in Riverside County heat for five or six decades. The wax ring gives out before the ceramic does. We see weeping seals, loose bowls, and cracked flanges constantly in ZIP codes 92585, 92586, and 92587.
- Washlet and Neorest control issues. Dry-season dust, heat cycling, and weak original bathroom exhaust fans are hard on electronic bidet boards and wands. If your Neorest controls are ghosting or the Washlet wand won’t extend, the bathroom environment matters as much as the circuit board.
- Skirted and Unifit-equipped Toto pulls that go sideways. Skirted one-piece toilets hide the floor bolts, and Unifit adapters need a level flange. On out-of-level Sun City slabs, a “simple swap” becomes a drain-alignment and subfloor job fast. We handle it without turning your hall bath into a construction zone.
- Tub-to-shower retrofits in narrow original hall baths. The single-story Del Webb floor plans squeezed bathrooms tight. Converting a tub to a low-threshold walk-in shower while keeping a Toto toilet in the same footprint is specialized work – and it’s one of the most common projects we do for 55-plus Sun City homeowners.
Toto Service in Sun City: What Local Conditions Mean for Your Equipment
Here’s what makes Sun City different from Menifee, Perris, or any neighboring city: Sun City was built out by Del Webb starting in 1962 and is now a 55-plus community under active HOA architectural review. That shapes every Toto bathroom project. A fixture move that changes an exterior vent penetration or a bathroom window requires HOA approval before we touch the outside wall. A tub-to-shower conversion that adds an exhaust fan vent needs the same review. Contractors who work Sun City regularly know this; contractors who drive up from Menifee often learn it the hard way. When you’re planning a Toto upgrade in Sun City, the HOA step is not optional – and we handle the application, the drawings, and the follow-up as part of the job. For the full scope of what we do in the area, see our Sun City service area page.
One example sticks with us. On a 1960s Del Webb ranch off Cherry Hills Boulevard in the 92586 ZIP, we converted a narrow hall bath from tub to low-threshold walk-in shower and re-set a Toto Drake on a badly out-of-level closet flange. The original wax ring had been weeping onto the slab for years. We chipped out and re-leveled around the flange, reset the Drake with a new OEM wax seal and supply, pulled an updated exhaust fan and GFCI for the client’s new Washlet, then walked the vent change through HOA architectural review before the exterior penetration went in. That’s what a Toto job in Sun City actually looks like.
Toto Models & Products We Service in Sun City
We regularly work on the Toto lines Sun City homes actually have installed:
- Toto Drake – both 1.28 gpf and dual-flush versions, the most common toilet in Del Webb-era bathrooms.
- Toto Ultramax II – one-piece, skirted, and unforgiving on out-of-level flanges. We pull and re-set these correctly.
- Toto Aquia – dual-flush, often paired with Washlet seats in updated Sun City bathrooms.
- Toto Washlet and Neorest – electronic bidet seats and integrated smart toilets, including control-board diagnosis, wand cleaning, and vent-ready installation.
Our parts approach is plain: genuine Toto OEM fill valves, flappers, and Unifit adapters on electronic and skirted models where fit is unforgiving, and quality aftermarket parts only where the spec allows. On older Sun City slabs we lean honest about repair versus replace. If the flange and drain are sound and the fixture is a good model, we repair it. If the flange is cracked or the pan is failing, a new Toto is cheaper than chasing leaks forever.

AfterToto Service Pricing in Sun City
Toto work in Sun City spans a wide range because a toilet re-set is one thing and a full tub-to-shower with a Neorest is another. Here are the line-item ranges we quote most often:
| Toto Service | Typical Price Range |
|---|---|
| Tub-to-Shower Conversion | $3,500 – $10,000 |
| Walk-In Shower Installation | $4,500 – $12,000 |
| Small Bathroom Remodel | $5,000 – $12,000 |
| Bathroom Vanity Installation | $800 – $3,000 |
What drives the cost: whether the flange needs re-leveling, whether the HOA review adds scope, whether the shower conversion requires moving a drain, and which Toto model you’re installing. A free estimate includes a look at the flange, the water supply, the venting, and the HOA-visible exterior changes. Call (855) 901-7266 for an exact quote – estimates are free.

FAQs – Toto Construction in Sun City
Yes, if any part of the Toto installation touches the exterior – a new exhaust vent, a changed window, a roof penetration – the Sun City HOA requires architectural review before work starts. We prepare the application, submit it, and schedule the work around the approval. A straight toilet swap with no exterior change typically does not require HOA review.
Hard inland water in Sun City leaves mineral scale on the fill valve and flapper, and eventually the tank can’t hold a seal. We replace the OEM fill valve and flapper, clean the mineral buildup, and the Drake runs like it did when it was new. If the flange is also failing, we’ll tell you before touching the fixture. Call (855) 901-7266 to schedule a look.
Yes – that’s one of the most common projects we do in Sun City. We reclaim the tub footprint for a low-threshold shower, keep or upgrade the Toto toilet in place, and handle the HOA review if the shower requires new venting or a window change. Narrow original hall baths are tight, but we’ve done enough of them in the 92585, 92586, and 92587 ZIPs to know the layouts.
A direct toilet swap usually doesn’t require a permit. Re-setting a toilet on a repaired flange, moving a drain, or adding electrical for a Washlet may – and we’ll tell you exactly which scope triggers it before we start. We pull permits when they’re required and get the inspections signed off.
For most Sun City homes, a standard Drake with a Washlet seat gives you 95% of the Neorest experience for significantly less money – and it’s easier to service if the electronics act up. We only recommend a full Neorest when the electrical, venting, and floor are ready for it. Call (855) 901-7266 and we’ll walk you through which route makes sense for your bathroom.
