Toto Construction in Mentone, CA | Stallion Contractors
We provide independent Toto installation and repair across Mentone, and the work here carries an extra layer most valley-floor contractors never touch: wildfire hardening. When we install or service a Toto fixture in a Mentone home, we’re accounting for ember-resistant venting, ash intrusion into fill valves, and water quality that shortens flapper life. Call (855) 600-3192 for a free estimate on Toto service, bathroom remodels, or tub-to-shower conversions.

Why Mentone Residents Choose Us for Toto Service
Ruben Montoya, owner of Stallion Contractors, grew up in Colton and trained through San Bernardino Valley College’s construction program, where the hands-on coursework put him on job sites before he carried a business card. Two-plus decades later, his crew still treats the final ten percent of a job like the first ninety. That matters in Mentone, where a bathroom remodel isn’t just about picking a toilet and roughing it in. The hillside drainage, the wildland edge, the dry air that wrecks rubber seals. We service Toto fixtures with full-scope contracting behind us: Toto sales & service, full bathroom remodels, walk-in shower installation, and tub-to-shower conversions all under one contract. One contractor. Every trade. For a Mentone homeowner replacing a failing Drake or adding a Washlet, that means no juggling a plumber, an electrician, and a general contractor.

Common Toto Construction Problems We Solve in Mentone
- Fill valve failure from mineral-rich water and ash debris. Mentone sits below the Crafton Hills, and after Santa Ana wind events, fine ash settles on roofs and sometimes finds its way into water supplies. Toto Eco UltraMax and Drake fill valves clog faster here than in Redlands or Loma Linda. We install OEM Toto fill valves and screen the supply line, which extends valve life measurably.
- Flapper seal deterioration from dry heat and temperature swings. A Toto flapper baking in an uninsulated Mentone bathroom sees 40-degree daily temperature swings in late summer. The rubber hardens, the toilet runs silently, and the water bill climbs. We replace with OEM Toto flappers, not the generic blister-pack ones that fail in a season.
- Washlet electronics failing from power surges. Santa Ana wind events knock out power lines across the 92359 corridor. A Toto S350e or S550e without surge protection can lose its control board in one event. We hard-wire Washlets through a surge-rated circuit and check manufacturer grounding specs before the seat ever lands.
- Tank bolt corrosion from wildfire ash exposure. Ash mixed with moisture creates a mild acid that pits tank-to-bowl hardware. In one mid-century home off Crafton Avenue, we pulled tank bolts so corroded they snapped during removal. We spec stainless hardware and check the tank gasket while we’re in there.
- Age-related bowl and trap wear. Mentone has a lot of older detached homes where the original Toto is 15-plus years old. A cracked bowl or worn trap isn’t worth fixing. We assess honestly: if replacement out-prices repair, we tell you before any invoice is written.
Toto Service in Mentone: What Local Conditions Mean for Your Equipment
Mentone sits in a wildland-urban interface zone where Chapter 7A-style ignition-resistant building requirements are the norm, not the exception. For a bathroom remodel with Toto fixtures, that shapes real decisions. Exhaust venting through eaves or gable ends must use ember-resistant vent covers. Wall assemblies behind a new walk-in shower may need noncombustible exterior details where the bathroom sits on a hillside wall facing chaparral. Valley-floor contractors a few miles west in Colton or Bloomington don’t routinely price this in. We do, because we run the Mentone service area often enough to know what the county inspector will flag on final. A Toto Vespin II installed with standard venting on a slope lot off the 38 corridor can fail inspection for ember protection, and then the homeowner pays twice. We spec it right the first time.
Toto Models & Products We Service in Mentone
We install and repair the Toto Eco UltraMax (MS854114E), the Drake line (CST743E/CST744E), the Vespin II (CST474CEFG), and the Washlet S350e and S550e bidet seats. For critical components like fill valves, flappers, and flush tower seals, we use OEM Toto parts exclusively. For less critical hardware like supply lines and angle stops, we use trade-grade aftermarket parts that meet our standard. That mix keeps turnaround fast in Mentone and keeps the Toto repair in Redlands honest. We stock common Toto fill valves and flappers on our trucks, so most repair calls don’t wait on a parts order.

AfterToto Service Pricing in Mentone
What a Toto in Yucaipa or Mentone repair or remodel costs depends on scope, access, and whether wildfire-hardening details apply. A fill valve replacement is a short service call. A full bathroom remodel with a Toto fixture lands in a different range entirely. Here’s the line-item breakdown:
| Service | Price Range |
|---|---|
| Bathroom Remodel | $9,000 – $28,000 |
| Walk-In Shower Installation | $4,500 – $12,000 |
| Tub-to-Shower Conversion | $3,500 – $10,000 |
A free estimate means we look at the rough-in, the venting, and the existing drain line before we quote a number. No square-footage guesses. Call (855) 600-3192 and we’ll schedule a walkthrough.

FAQs – Toto Construction in Mentone
Yes. We stock OEM Toto fill valves on our trucks for the Eco UltraMax, Drake, and Vespin II, so most fill valve replacements in Mentone are done in a single visit. Call (855) 600-3192 to schedule, and we’ll confirm the model before we arrive.
Not special in the code sense, but we hard-wire Washlets through a dedicated GFCI circuit with surge protection. Santa Ana wind-driven outages and voltage spikes will fry a Washlet control board quickly without it. For an exact quote on your bathroom’s electrical setup, call (855) 600-3192.
It affects venting and exterior wall assemblies. Bathroom exhaust vents in Mentone must use ember-resistant covers, and exterior walls on slope lots facing chaparral may need noncombustible details before tile or fixtures go in. We price these into the estimate upfront rather than discovering them at inspection, and we offer Toto service in Highland with the same upfront approach.
A small bathroom remodel starts around $9,000 and runs up to $28,000 depending on shower type, tile, venting, and whether plumbing needs to move. Walk-in shower installation ranges $4,500 to $12,000, and tub-to-shower conversion runs $3,500 to $10,000. Call (855) 600-3192 for a free line-item estimate on your Mentone home.
Yes. Tub-to-shower conversion is one of the most common projects we complete in Mentone’s older single-family homes, where the original tub has outlived its use.
