Bathtub refinishing typically runs $350–$600 for a standard tub. That’s the honest number for a professional job in most parts of the country. But prices vary, and the range matters — because a $150 quote and a $600 quote are not the same service, not even close.
I’ve been refinishing tubs professionally for over 20 years. Here’s exactly what drives cost, what questions to ask before you hire anyone, and what the DIY option actually costs.
What a Standard Refinish Costs
For a typical 5-foot cast iron or fiberglass tub in decent condition, expect to pay:
- $350–$450 in most mid-cost markets
- $500–$600 in high-cost metros (New York, LA, Seattle, etc.)
- $600–$900+ for jetted tubs, large soaking tubs, or tubs needing significant repair
That price includes labor, materials, and masking. It does not include replacing your caulk lines permanently (most refinishers will caulk the tub after, but some charge extra for a full silicone-removal-and-re-caulk service).
What Makes It Cost More
Not every tub is a straightforward $400 job. Here’s what adds to the price:
Heavy rust or pitting. Surface rust you can sand through is normal. But if rust has eaten into the porcelain and left pitting deeper than 1/8 inch, the refinisher needs to fill and sand those spots multiple times. Add $50–$150 depending on severity.
Fiberglass cracks. A fiberglass tub with stress cracks needs to be stop-drilled, patched, and faired before any coating goes on. Budget $100–$200 more for a cracked fiberglass tub.
Large repairs. Missing chunks of porcelain, deep gouges, or cracks that go through the shell — these require more time and materials. Honest refinishers will quote you for this upfront.
Jetted tubs. More surface area, awkward geometry around the jets, and often more tape-out time. Expect $600–$1,000.
Existing refinish removal. If someone already refinished the tub badly and it’s peeling, the old coating has to come off before a new one goes on. Stripping a tub adds time and cost.
The Red Flag: Suspiciously Cheap Quotes
If someone is quoting you $150–$200 to refinish a tub, walk away.
I know that sounds harsh. But at that price, they are either:
- Using hardware-store-level products with terrible adhesion
- Skipping proper prep (no acid etch, no silicone removal, no real cleaning)
- Rushing — fitting 3–4 jobs in a day instead of 1–2
Any of these means your finish is peeling in 6 months. I’ve seen it hundreds of times. Customers call me to re-refinish a tub that was “just done” by someone who charged $180 and was out the door in 45 minutes.
A proper refinishing job takes 3–4 hours minimum for one tub. If someone’s doing it in an hour, they’re cutting corners on the prep that makes the finish actually stick.
Questions to Ask Before You Hire Anyone
Before you book a refinisher, ask these:
What products do you use? Professional-grade products matter. Hawk Research Laboratories makes coatings that most serious refinishers use. If they can’t name their product line, that’s a problem.
How many jobs do you do in a day? One to two jobs per day is normal. Two is on the high end but workable if they’re efficient. Three or more jobs in a day means they’re rushing — and prep is always what gets rushed.
Do you remove the drain? Yes is the right answer. You cannot properly tape around a drain and get clean edges. Removing it takes 10 minutes and makes a real difference.
Do you acid etch the surface? On porcelain, acid etching creates microscopic tooth for the coating to bond to. This is a required step on porcelain tubs. If they don’t do it, adhesion will fail.
Do you remove all silicone caulk before refinishing? Silicone contamination is the number one cause of peeling. Any silicone left on the surface — even invisible residue — will cause the coating to lift. Ask if they use a silicone digester or just a razor blade.
DIY Cost: The Real Number
If you want to do it yourself, you’re looking at $30–$80 for a consumer refinishing kit — versus $350–$600 for professional work.
That’s a real difference. The tradeoff is that consumer kits don’t match professional products for adhesion and longevity. A DIY job done well can last 5–10 years. A poorly done DIY job (skipped prep, wrong products) lasts months.
If you go DIY, the prep is 80% of the job. Don’t skip it.

Refinishing vs. Full Replacement
Refinishing at $350–$600 compares very favorably to a full tub replacement. A standard fiberglass tub swap runs $1,646–$2,781 in 2026 once you factor in labor, materials, and disposal. If your tub is structurally sound and you just want it to look new again, refinishing is the clear value play.

Bottom Line
A fair price for professional bathtub refinishing is $350–$600. Anything under $200 should raise serious questions. Anything over $700 for a standard tub should also raise questions unless there’s significant repair work involved.
Ask about products and prep before you book. A refinisher who can answer those questions clearly is a refinisher who takes the work seriously.
