Bathroom remodeling in Colton typically runs $9,000 – $28,000 for a full remodel, with tub-to-shower conversions starting around $3,500. Those numbers move based on what’s behind your walls, and in Colton, that usually means something unexpected. Our crews work throughout the city weekly, from older homes near Colton Crossing to the 1980s tract developments off La Cadena Drive, and we answer the phone at (936) 259-2607 when you’re ready to talk numbers.
Key Takeaways:
- Full bathroom remodels in Colton run $9,000 – $28,000; small baths run $5,000 – $12,000
- Colton’s expansive adobe and clay soils cause slab movement that shows up as cracked shower pans and failed waterproofing
- Pre-1960s homes here routinely hide cloth wiring and undersized framing behind bathroom walls
- Every project gets a written price before work starts and a 365-Day Done Right Promise in writing
Why Penhallow Remodeling Is Colton’s Preferred Bathroom Remodeling Company
Colton homeowners call us because we write the number down before we pick up a tool. Trevor Nash leads our Bathroom Remodeling team with one rule: the price on day one is the price on the final invoice, unless you approve a change in writing first. That matters in a city with as much housing age diversity as Colton, where a 1950s wood-frame home off Valley Boulevard and a 1990s stucco tract house near Grand Terrace need completely different approaches.
Our background-checked, uniformed crews know what a Colton permit inspection will flag, because we’ve sat through enough of them. We know that San Bernardino County permitting for a residential bathroom moves through the same pipeline as the city’s industrial tilt-up projects, so we schedule inspections with that reality in mind. When you call (936) 259-2607, a real person answers, 24/7. Not a voicemail maze.
Tub to Shower Conversion in Colton
A tub to shower conversion in Colton runs $3,500 – $10,000 and replaces your existing bathtub with a walk-in shower built on a properly sloped, waterproofed base. Colton homeowners choose this when a tub no longer fits their needs, whether that’s mobility, cleaning, or simply wanting more usable floor space in a compact bathroom.
What We Do Before Demo
Before we open anything, we check the slab. Colton’s older residential grid sits on expansive adobe and clay-rich soils that heave and crack far worse than the sandier ground in Rialto or Fontana, so a bathroom remodel here often begins with foundation and footing review before the first tile is set, not just a cosmetic tear-out. If the slab has moved under the existing tub, we need to know that before we build a new shower base on top of it.
What the Conversion Includes
We install a cement board substrate (the moisture-resistant layer behind your tile), a properly sloped shower pan, new valve and trim from Kohler or Moen, and either a curtain rod or frameless glass enclosure depending on your layout. The permit gets pulled, the inspection gets scheduled, and the price stays what we wrote down unless we find something structural you approve in writing before we proceed.
One Day Bath Remodel in Colton
A one day bath remodel in Colton typically lands between $5,000 – $12,000 and focuses on replacing the existing tub or shower surround with a custom-fit acrylic or composite system installed over a reinforced substrate. It’s the right fit when the bathroom is functionally sound but cosmetically worn, and the homeowner wants the job done without living through a two-week construction zone.
When a One Day Install Works
This works best in Colton bathrooms where the subfloor and framing are solid and the existing plumbing is already up to current code. If we find rot, failed waterproofing, or undersized framing, we stop, show you what we found, and give you a written change order before any additional work happens.
What We Don’t Rush
We don’t rush waterproofing, and we don’t cover up problems to hit a clock. Bathtub replacements and shower surrounds on the one day path still get the same inspection and the same 365-Day Done Right Promise as a full remodel. If it’s not done right, we come back and fix it at no charge, covered in writing.
Trusted Brands We Service in Colton
We install products from trade brands that stand behind their work, including Cambria quartz for vanity tops, Kohler and Moen fixtures, and Wellborn cabinetry. If you’re considering a prefabricated or panelized approach for a larger remodel, we’ve worked with systems from Cover and Abodu where the project scope benefits from off-site fabrication. For Colton customers, that means we can order replacement parts locally or through our supplier network without weeks of delay, and we stand behind the installation with the same written guarantee regardless of which brand you choose.
Common Bathroom Remodeling Problems We See in Colton Homes
- Slab movement from expansive clay soils. Colton’s adobe and clay-rich ground heaves seasonally, which cracks shower pans and breaks waterproofing membranes. The leak goes undetected until water reaches the subfloor and rot sets in.
- Cloth-wrapped or aluminum wiring in pre-1960s homes. Opening a bathroom wall in an older Colton house often reveals wiring that no longer meets code. Once the permit is pulled, the electrical upgrade becomes mandatory, which affects scope and schedule.
- Failed waterproofing behind old tile. Original bathrooms from the 1940s through 1970s frequently lack proper moisture barriers. By the time you see cracked grout or peeling paint, the studs behind the tile may already be compromised.
- Undersized framing around original tubs. Older Colton homes were built with different load assumptions. When we replace a cast iron tub with a heavier soaker or add a tiled shower wall, the floor framing may need reinforcement to pass inspection.
On a pre-1960s wood-frame home near the Cooley Ranch area, our crew opened a bathroom wall and found cloth-wrapped wiring, undersized framing around the old tub, and a shower pan that had been leaking into the subfloor for years, all of which the permit inspection would have flagged anyway. We pulled the permits, wrote allowances for the wiring and framing into the scope of work, and priced the extra work as a signed change order before we touched a single stud, then scheduled the rough-in for early morning to beat the 110°F Inland Empire heat.

FAQs About Bathroom Remodeling in Colton
Colton’s expansive adobe and clay soils move more than the sandier ground in Rialto or Fontana, which means slab and footing review is often required before tile work begins. That inspection, plus the likelihood of code upgrades on pre-1960s homes, adds legitimate cost. We write allowances into every Colton contract so you know the potential ceiling before we start. Call (936) 259-2607 for an exact quote on your home.
You usually find cloth-wrapped wiring, undersized framing, or hidden water damage, and once the permit is pulled, the code upgrades become mandatory. That’s why we build inspection-first pricing into every older-home remodel in Colton, with written allowances for the most common surprises and signed change orders before any additional work. The number on day one stays the number on the invoice unless you approve a change.
Yes, if we’re moving the drain, altering the valve, or changing anything structural, a San Bernardino County permit is required. We pull the permits, schedule the inspections, and make sure the work passes before we call it done. No permit, no final sign-off, and no warranty, that’s our rule.
We write a line-item allowance for the most common surprises, like rotted subfloor or outdated wiring, into every contract before we start. If we find something outside that allowance, we stop, show you the problem, and get a signed change order with a written price before we do another dollar of work. You never get a bill you didn’t approve in writing first.
Yes, if the subfloor, framing, and plumbing check out in the initial inspection. If we find structural issues, we’ll recommend a different scope and give you a written price for that before proceeding. Either way, the work gets the same inspection and the same 365-Day Done Right Promise. Call (936) 259-2607 to schedule a free estimate for your bathroom.
