Fast, Reliable Bathroom Remodeling Across Windsor
A full bathroom remodel in Windsor runs $9,000 to $28,000, and the price depends almost entirely on what’s behind the walls: the age of the drains, the condition of the subfloor, and whether the original 1960s plumbing needs to come out. We’re Sawyer Remodeling, led by Luca Romano, and we’ve worked inside enough Windsor homes to know the difference between a cosmetic refresh and a gut renovation. Most of what we do here starts with ripping out cast-iron drains and discovering what the last three owners left underneath the tile. Call (254) 272-5876 for a written estimate before any work starts, because the number you approve is the number you pay.
Why Sawyer Remodeling Is Windsor’s Preferred Bathroom Remodeling Company
Windsor homeowners call us because we run every project under The Relay Visibility Guarantee: a live arrival time, before-and-after photo updates, and a written price before a single tool gets picked up. That’s not a courtesy. It’s the standard. When we say our tech will be at a home off Old Redwood Highway at 8:30, they’re there at 8:30, uniformed and background-checked, and the person on the phone at (254) 272-5876 answers live no matter when you call. No voicemail loops.
We’ve remodeled bathrooms in the Windsor Landings neighborhood, in homes near Windsor High School, and in the Foothill Ranch subdivisions east of 101. What we’ve learned from that work is that Windsor’s housing stock rewards contractors who scope honestly. A 1968 hall bath with original cast-iron and a rotted subfloor is not the same job as a 2005 spec bath that just needs new tile. We price them differently, and we explain why in the scope of work. That’s why homeowners who compare quotes tend to call us back after talking to lower bidders who didn’t pull the subfloor.

Tub to Shower Conversion in Windsor
A tub-to-shower conversion in Windsor runs $3,500 to $10,000, and the spread comes down to what the crew finds when the old tub comes out. In Windsor’s 1950s through 1970s housing stock, a tub-to-shower conversion almost always means demolishing to the studs around the drain, checking for dry rot in the subfloor, re-framing the rough-in if the joists are compromised, and setting a new shower base. We handle demo, drain re-set, waterproofing, and finish work, and we pull the permit before we start. If the Town of Windsor’s building department flags the alteration because the home falls in a FEMA-mapped floodplain zone, the permit review takes longer and the timeline adjusts. We tell you that up front, not after demo day.
Waterproofing and Drain Replacement
The most important part of a tub-to-shower conversion in Windsor is what you never see: the waterproofing membrane, the slope of the drain pan, and the venting behind the wall. We use Schluter edge trim, the metal strip that waterproofs where tile meets the floor, and we set drains so water moves instead of pooling. If the original cast-iron drain is cracked or collapsed, we replace it before we set the new shower base. That’s the difference between a shower that lasts twenty years and one that leaks into the floor joists by year three.
What It Costs and What Changes the Price
A basic tub-to-shower conversion with a Kohler or Moen shower base, new valve, cement backer board, and standard tile starts around $3,500 in Windsor. If the subfloor around the old drain has dry rot, which we see often in 1960s homes off Arata Lane and in the area near Keiser Park, the repair adds $800 to $1,500 before any finish work. A frameless glass enclosure instead of a curtain adds $800 to $2,000 depending on size. We write every one of those numbers on the scope of work before we start, and if something changes once we open the wall, you sign a change order before we spend another dollar.
One Day Bath Remodel in Windsor
A one day bath remodel in Windsor is a defined scope: replace the tub or shower surround, swap the shower valve and trim, and install new waterproof wall panels in a single visit. We don’t call a full gut renovation a one-day job, because that would be a lie. What we offer is a same-day transformation for a shower that’s cosmetic-failed but structurally sound, with acrylic or composite wall panels from manufacturers like Dvele that install cleanly over prepped studs. The realistic cost for that scope in Windsor is $4,000 to $9,000, depending on the footprint and the condition of the rough-in.
What’s Included and What’s Not
A one day bath remodel includes demo of the old surround, prep of the wall cavity, installation of the new waterproof panels, new valve trim, caulking, and cleanout. It does not include moving plumbing, changing the footprint, replacing a rotted subfloor, or re-tiling a custom shower floor. If our Windsor crew finds rot or failed waterproofing, we stop and give you a change order before we proceed. We don’t bury that reality in fine print. We put it in the scope of work, with a line item.
When It Makes Sense in Windsor
If you’re in a Windsor home built in the last thirty years and the shower surround is cracked or stained but the pan is intact, a one day remodel gets you a clean, waterproof shower without weeks of dust. If the home is older and the drain is cast-iron, we recommend a full tub-to-shower conversion instead. Our estimator will tell you which one your house actually needs when they pull the access panel and look. That honesty is why Windsor homeowners call us for second opinions after getting quotes from companies that never looked under the pan.
Trusted Brands We Service in Windsor
We install Kohler, Moen, and Grohe fixtures, and we work with Cambria, Silestone, and Caesarstone for vanity tops, plus Mighty Buildings and Cover for prefabricated shower panels. For Windsor customers, that means you’re choosing from name-brand materials with manufacturer backing, not whatever the local supply house had on clearance. We keep a running inventory of the most common replacement parts for Windsor’s typical valve and trim styles, so a failed Moen cartridge or a cracked Kohler drain flange doesn’t mean a three-week wait. You pick the finish, we handle the sourcing and the install, and the price is in writing before the order goes through.

AfterCommon Bathroom Remodeling Problems We See in Windsor Homes
- Dry rot around the tub drain. Windsor’s 1960s and 70s homes frequently have plywood subfloors that rotted silently around the tub drain because the original installer never sealed the overflow properly. We find it in maybe one out of every three older baths we open up.
- Unpermitted unpermitted work from a previous flip. A homeowner buys a Windsor house, discovers the hall bath was remodeled without a permit, and now the shower plumbing isn’t vented. During resale, the Town of Windsor building department flags it, and the wall has to come open again.
- Cast-iron drains at the end of their life. Windsor’s older core, platted in the 1950s through 1970s, has cast-iron drain lines with a service life that expired years ago. We routinely find pipes so rusted you can put a screwdriver through them.
- Flat bids with no allowances. A contractor gives Windsor homeowners a low flat bid and then acts surprised when the Cambria counter they picked costs $2,500 more than the generic laminate in the quote. Without a written allowance schedule, that becomes a fight instead of a line item.

FAQs About Bathroom Remodeling in Windsor
Do I need a building permit to remodel a bathroom in Windsor, CA?
Yes, if your remodel involves plumbing, electrical, or structural changes, including moving drains, changing the shower valve, or re-framing around a rotted subfloor, the Town of Windsor building department requires a permit and inspection sign-off. We pull the permit, schedule the inspections, and don’t close the wall until the inspector approves the rough-in. Unpermitted work gets flagged during resale and has to be opened back up. Call (254) 272-5876 for a scope of work that includes the permit, because it should never be optional.
What does a tub-to-shower conversion actually cost in Windsor, and what drives the price?
A tub-to-shower conversion in Windsor runs $3,500 to $10,000. The base job includes demo, drain re-set, waterproofing, and a standard shower base. The price moves when we find dry rot around the old tub drain, which is common in Windsor’s 1960s and 70s homes and can add $800 to $1,500, or when you choose a frameless glass enclosure, which adds roughly $800 to $2,000. Every change is a signed change order before we proceed. Call (254) 272-5876 for an exact written quote.
Can you do a one-day bath remodel in Windsor, and what’s included?
Yes, when the scope fits: replacing a shower or tub surround, swapping the valve and trim, and installing new waterproof wall panels in a single day, without moving any plumbing or touching the subfloor. That scope typically runs $4,000 to $9,000 in Windsor, and it’s designed for showers with cosmetic damage but solid bones. If the pan or drain is compromised, we’ll recommend a full conversion instead. Call (254) 272-5876 and our estimator will look under the access panel before you commit to anything.
What’s included in a bathroom remodel quote, and why do estimates seem to vary so much?
Our Windsor quotes include a line-item breakdown for demo, plumbing rough-in, electrical, waterproofing, tile labor, fixtures, and material allowances. Estimates vary because some contractors leave out the permit, skip the subfloor inspection, or write material allowances so low that any real material choice becomes a “surprise” change order. We don’t do that. The number on our signed scope of work is the number you approve, and if we find hidden rot, you approve the change before we touch it. That’s The Relay Visibility Guarantee, and it’s written into every Windsor quote.
How long does a bathroom remodel take in Windsor from start to finish?
A typical tub-to-shower conversion in Windsor takes five to eight working days, which includes demolition, rough-in, permit inspection, waterproofing, tile, finish, and final inspection. A full bathroom remodel takes two to four weeks, depending on whether the home needs drain replacement or subfloor re-framing. If the home lies in a FEMA-mapped flood zone, plan for additional permitting review time, which we’ll flag during the estimate. You’ll get a week-by-week calendar in your scope of work, not a vague “it depends.” Call (254) 272-5876 to schedule your free written estimate.
