Refinishing and replacement occupy completely different cost tiers. Refinishing is a surface treatment — a professional applies a bonding primer and polyurethane or epoxy coating that restores the appearance of the tub. Replacement means removing the old tub and installing a new one, which often involves some tile or surround work as well.
| Option | Cost Range | Lifespan | Time to Complete |
|---|---|---|---|
| Professional refinishing | $300–$600 | 3–5 years | 1 day (+ 24hr cure) |
| DIY refinishing kit | $30–$90 | 1–3 years | 1 day |
| Tub liner (acrylic overlay) | $800–$1,500 | 10–15 years | 1 day |
| Basic tub replacement (alcove) | $1,200–$3,000 | 20–30 years | 2–3 days |
| Mid-range replacement | $2,000–$5,000 | 20–30 years | 3–5 days |
| Freestanding/luxury tub | $3,000–$8,000+ | 20–30+ years | 3–5 days |
Refinishing is the right call when: the tub is structurally sound with only cosmetic damage (surface scratches, dulled finish, minor staining); you are not planning a full bathroom remodel in the next few years; you need a cost-effective solution for a rental property or a short-term fix; or the tub size and style works for the space and you simply want to refresh the appearance. A professionally refinished tub looks close to new and can extend the life of a functional fixture for several years at minimal cost — a genuine value in the right context.
Replace when: the tub has structural cracks, chips through to the substrate, or signs of rust (especially in cast iron tubs); you are planning a full bathroom remodel anyway and want the surround refreshed simultaneously; you want a different size, style, or material (freestanding, soaking tub, walk-in tub); or you have refinished the same tub twice already and the coating is failing again. Refinishing a cracked tub only masks the problem — water infiltration beneath the tub will continue and cause subfloor damage that costs far more to address than a tub replacement would have.
DIY refinishing kits ($30–$90) use isocyanate-based coatings that require serious ventilation and a proper respirator — not a paper dust mask. Inhalation of these fumes is a genuine health hazard recognized by OSHA. Application errors — brush marks, uneven coats, inadequate surface prep — result in a finish that peels within 6–18 months. Professional refinishers use spray equipment, commercial bonding agents, and topcoats rated for long-term wet exposure. The $250 premium over DIY is almost always worth it for safety and durability reasons alone.
A tub liner is a custom-molded acrylic or PVC shell that fits over your existing tub. Cost: $800–$1,500, lifespan 10–15 years — a middle path between refinishing and full replacement. The primary concern: some liners trap moisture between the old tub and new shell if the adhesive has any gaps, which creates mold that is invisible and difficult to remediate. Reputable companies with professional installation avoid this issue, but many contractors prefer to recommend either refinishing or outright replacement to eliminate the moisture trap risk entirely.

Refinishing is a legitimate short-term fix for a tub that's cosmetically rough but structurally fine, just don't treat it as permanent. Plan to actually replace it at your next full remodel, 5-7 years out.
