Sunnyvale Bathtub Reglazing Projects & Case Studies

How to read these case studies

Eight Sunnyvale jobs, told straight

Written by Islam Makchachev, Lead Refinisher at Sunnyvale Bathtub Resurfacing — spraying tubs across Sunnyvale and the Santa Clara Valley since 2014. Last updated: June 2026.

I have read and sprayed enough Sunnyvale bathrooms by now that the calls sort themselves into a handful of patterns. The fiberglass unit in a Ponderosa rental fails the same way every time. The cast-iron tub in a Cherry Chase ranch house rusts at the drain on the same schedule. So instead of fabricating named customers and invented dates, the eight write-ups below are honest, representative versions of the projects I run most — each tied to a real Sunnyvale neighborhood and the housing stock that sits there. When I say "a typical Heritage District clawfoot job," that is exactly the work, the prep, the time and the cost I have logged across that area, not a one-off story dressed up to sell.

Each case study names the neighborhood, the fixture and what it was made of, the starting condition, the prep and repair I did, how many coats went on, the outcome, the turnaround time and a cost range. The photos that go with this kind of work are on the before-and-after gallery — this page is where I explain what actually happened between the two shots. Read it the way you'd ask a refinisher to walk you through his last week of jobs. If one of these is close to the tub you're looking at, the number and the timeline will be close to yours too.

Project 01 · Cherry Chase (94087)

1950s porcelain-over-cast-iron tub, Cherry Chase ranch home

The fixture and the problem. Cherry Chase is mostly single-family ranch and Eichler-era homes from the 1950s and 60s, and the original bathrooms still carry their heavy porcelain-over-cast-iron tubs. This one was a standard 5-foot alcove tub: the enamel had gone matte and chalky from decades of cleaning, there were two chips down to the iron at the rim, and a ring of surface rust had bloomed around the drain where the glaze wore through. The owner wanted it white and smooth again without ripping out a tub that still rang solid when you tapped it.

What I did. Cast iron is the easiest material to bond to once it's clean. I masked the room and set up containment and forced ventilation, then deep-cleaned to strip soap film and body oils. I cut the rust back to sound metal so it couldn't bleed through, filled the two rim chips and faired them flat, and acid-etched the porcelain so the bonding primer would grip. Then three thin sprayed coats of acrylic-urethane — thin coats instead of one heavy run that sags — and fresh re-caulk before I left.

Outcome, time and cost. Glossy bright white, the rust gone, the chips invisible. On-site work was about four hours; the tub cured overnight and was back in use the next afternoon. A clean cast-iron Cherry Chase job like this lands at the low end of the tub range, roughly $735–$790, because the material etches cleanly and the only repair is cosmetic. This is the most predictable tub I price in Sunnyvale.

Project 02 · Ponderosa (94086)

1980s fiberglass tub-and-shower unit, Ponderosa rental turnover

The fixture and the problem. Ponderosa is wall-to-wall 1970s and 80s apartments and condos, and the everyday call here is a one-piece molded gelcoat fiberglass tub-and-shower unit between tenants. This one had gone the classic route: chalky and yellowed across the floor, a web of crazing — fine spider-cracks — through the high-wear zone, and a soft, stained spot near the drain. A property manager needed it bright white and rentable before the next lease started.

What I did. Fiberglass is more prep, not less. You can't acid-etch gelcoat the way you etch porcelain, so it gets a thorough scuff-sand to give the primer a mechanical key. I filled the crazing and faired it smooth, reinforced the soft floor spot, then wiped the whole unit down with a solvent to pull any remaining mold-release and chalk. Bonding primer, then three sprayed acrylic-urethane coats. On a turnover I'm always working to a hard deadline, so the containment and ventilation go up fast and the unit is masked tight to keep overspray off the new tile.

Outcome, time and cost. Even, bright, factory-white — the yellowing and crazing gone, the floor solid underfoot. Roughly four to five hours on site, cured and tenant-ready inside two days. A chalky, crazed fiberglass unit runs a touch higher than clean cast iron because of the added prep, about $775–$845. Property managers around Ponderosa and Ortega Park book these constantly, often a tub and a sink in the same trip to drop the per-fixture cost.

Project 03 · Heritage District (94086)

Antique clawfoot tub, Heritage District bungalow

The fixture and the problem. The bungalows around the Heritage District keep their period bathrooms, and a freestanding cast-iron clawfoot tub is the one fixture nobody wants to lose. A typical one here has a worn, discolored interior, an exterior that's been painted and chipped over the decades, and feet that have gone dull. The owners want the antique look kept and the wear gone — replacing it with a modern reproduction would cost far more and lose the character.

What I did. A clawfoot is more work than an alcove tub because there's no wall hiding three sides — the inside, the outside roll, and often the feet all get finished. I masked the floor, deep-cleaned, sanded the old exterior paint back to a sound base and etched the porcelain interior. Chips filled and faired, then I sprayed the interior in a bright restoration white and finished the exterior in the color the owner chose. Clawfoots reward patience: thin coats, extra cure time between them, and careful masking around the rolled rim.

Outcome, time and cost. A clean, smooth interior and a crisp exterior that keeps the tub's vintage shape — a restored original, not a replacement. Because all sides are finished, a Heritage District clawfoot runs at the upper end, roughly $850–$1,050 depending on whether the feet and exterior are included. On-site time runs longer than a standard tub, but it's still typically a one-day job with an overnight cure. More on this work is on the clawfoot & antique tub refinishing page.

Project 04 · Lakewood (94089)

Failed DIY refinish stripped and redone, Lakewood condo

The fixture and the problem. Lakewood's north-city apartment communities run the same 1980s gelcoat stalls as Ponderosa, and every so often a tenant or owner tries a hardware-store kit first. This kind of job is what's left after that: a roll-on DIY coat peeling in sheets along the tub floor, lifting at the drain, with the original surface exposed in patches. The kit skipped the etch and the spray, so it never bonded, and now there are two problems to solve instead of one.

What I did. The failed coat has to come off before anything new goes on. I stripped the loose DIY film back to a sound surface, which is the labor that makes this job different — there's no shortcut to it. Once it was back to clean, stable gelcoat, the work is the standard fiberglass routine: scuff-sand, fill and fair any damage the strip revealed, solvent wipe, bonding primer, three sprayed acrylic-urethane coats. The reward for doing the stripping properly is that the new finish bonds the way the kit never could.

Outcome, time and cost. A uniform, glossy white surface that holds the same 10–15 years as any fresh tub — the peeling gone for good. Because of the stripping, this lands at the top of the range, about $850–$890. The lesson I give every Lakewood caller who's eyeing a $40 kit: a failed DIY job becomes the kit price plus a stripping surcharge plus the full reglaze, more than just paying once. See why on the cost page.

Project 05 · Birdland (94087)

Porcelain sink and tub-surround tile, Birdland home

The fixture and the problem. Birdland's mid-century homes often have a dated bathroom that's structurally fine but reads old — in this representative job, a worn porcelain sink with a front chip and rust at the overflow, paired with an almond tub-surround tile wall with stained grout. Replacing both means demolition and a new vanity and re-tiling. The owner wanted it all matched to a clean white in a weekend, not a remodel.

What I did. This is a multi-surface job, which is where booking together pays off — I mask, contain and ventilate the room once and finish two surfaces in it. The sink got an etch, a chip-fill at the front, rust cut back at the overflow, then two sprayed coats. The tile wall, grout lines and all, got a deep clean, an etch, and a recolor to bright white, so the almond and the stained grout both disappear under an even finish. No demolition, no new tile, no plumber.

Outcome, time and cost. A flawless white sink and a clean white surround that make the whole bathroom look updated. A sink runs $420–$495 and tile surrounds start at $530, and done together in one visit the pair costs less than two separate trips. On-site time was most of a day across both surfaces. See the sink reglazing and tile reglazing pages for the details on each.

Project 06 · Ortega Park (94086)

One-piece fiberglass shower stall, Ortega Park rental

The fixture and the problem. Around Ortega Park the rentals lean heavily on fiberglass, and a one-piece gelcoat shower stall is a common turnover call. The representative version: chalky and yellowed walls, crazing through the lower panels, and a floor that had lost its non-slip texture and gone slick. A property manager wanted it bright and safe before re-leasing, and asked for slip resistance added back to the floor.

What I did. A shower stall is more square footage than a tub, so it's more masking and an extra coat. Scuff-sand the gelcoat, fill the crazing, solvent wipe, bonding primer, then three sprayed acrylic-urethane coats up the walls. For the floor I sprayed in a slip-resistant texture rather than leaving it glass-smooth — the safety add-on a lot of rental and family bathrooms ask for. Fresh re-caulk at the joints before I left.

Outcome, time and cost. An even bright-white stall with a grippy floor, ready for the next tenant. A shower stall runs $935–$1,040 because of the size, with the slip-resistant floor a small add-on. On-site time was about five hours, cured and back in service inside two days. The slip-resistant texture is its own topic on the non-slip coating page, and shower work lives on shower refinishing.

Project 07 · Washington Park / Raynor (94086)

Chip and hairline-crack repair, Washington Park ranch home

The fixture and the problem. Not every project is a full reglaze. The central neighborhoods around Washington Park and Raynor mix ranch homes and rentals, and a common call is a single failure on an otherwise sound tub — a deep chip where something heavy was dropped, plus a hairline crack starting to spread from it. Left alone, water gets behind the enamel and the chip turns into rust and spreading damage. The owner wanted it fixed before it grew, not the whole tub redone.

What I did. A targeted repair is about matching, not coverage. I cleaned and cut out the loose material around the chip, stop-drilled and filled the hairline crack so it couldn't keep traveling, then built the chip back up in layers and faired it flush. The repaired area got a color-matched topcoat blended into the surrounding finish so it disappears. When the surrounding glaze is in good shape, this is a spot fix; when it's worn overall, I'll recommend a full reglaze instead so the whole surface matches.

Outcome, time and cost. The chip and crack gone, the spread stopped, the repair invisible against the original surface. A spot chip-and-crack repair is the quickest project I do — a couple of hours on site — and the cheapest, well below a full tub reglaze. Details and the honest "repair vs. full reglaze" call are on the tub chip & crack repair page.

Project 08 · Sunnyvale West / Murphy Avenue (94087 / 94085)

Oversized soaking tub recolored, Sunnyvale West condo

The fixture and the problem. The newer condos out toward Sunnyvale West and downtown Murphy Avenue sometimes hide a bigger fixture than you'd expect — a 6-foot drop-in soaking tub in a dated color that clashes with an otherwise modern bathroom. The tub was structurally sound but the wrong shade, with light surface wear. The owner didn't want to lose a heavy soaking tub they'd otherwise keep; they wanted it modern white.

What I did. An oversized tub is the same process with more of everything — more surface to mask, more square footage to etch, an extra coat to cover the larger area evenly. I etched the porcelain, addressed the light wear, and sprayed it in a clean bright white, confirming the color against the surround before any coats went on. On a recolor I'm careful with the cut lines at the rim and deck so the new shade reads crisp against the tile.

Outcome, time and cost. A large soaking tub in modern white that fits the room — the dated color gone, the tub kept. Because of the size and the extra coat, an oversized recolor lands toward the top of the tub range, about $830–$875. On-site time runs a bit longer than a standard alcove tub. Color options, including off-whites and neutrals, are a common request across these newer condos — ask when you book.

Straight about these examples

Why these are representative, not invented testimonials

I want to be plain about what you're reading. These eight write-ups are honest, representative versions of the work I run in each named Sunnyvale neighborhood, built from the patterns I see again and again — the Cherry Chase cast-iron tub, the Ponderosa fiberglass turnover, the Heritage District clawfoot. They are not invented stories with fake customer names, made-up quotes, fabricated dates or a pretend review count attached. When I tell you a clean Cherry Chase cast-iron job runs $735–$790 in about four hours, that's the real number and the real timeline from that kind of fixture, every time.

The matched before-and-after photos for this kind of work are on the before-and-after gallery — same fixtures, shot from the same angle before and after. What you won't find anywhere on this site is a coat sprayed without the prep behind it. The prep is the part the after photos hide and the part that decides whether a finish lasts a decade, and you can read the full step-by-step on our process page. Honest examples, real prices, real prep. That's the whole pitch.
