Wear versus damage
Dullness and roughness are wear. Cracks, flexing or water getting through are damage, and they change the conversation.
Aging tub surfaces
Decades of baths can wear a tub's surface down evenly, leaving it dull, rough or thin where feet and water land most. The question is whether the tub underneath is still worth keeping.
Short answer
General surface wear on an older tub can sometimes be refreshed by refinishing, if the tub is solid and the shape still suits you. When the tub is cracked, moves underfoot, or no longer fits how the household bathes, replacement or conversion may be the better long-term step. A provider can look at the tub and explain which direction seems realistic.

Considerations
Dullness and roughness are wear. Cracks, flexing or water getting through are damage, and they change the conversation.
Some older tubs are heavy and solid under a tired surface. Others are thinner and may not suit another coat.
A tub that still suits the household is a good candidate to keep. One that is hard to enter or rarely used may not be.
If the walls are also worn, a tub-only refresh may leave the area looking mismatched.
Safe observations
A larger project may make sense when wear comes with damage, or when the tub no longer suits the household. Bathtub replacement brings a new fixture, while a conversion may change how the space is used.
When the tub is sound and only the surface is tired, bathtub refinishing is the path to explore in more detail. For a side-by-side look, see bathtub refinishing vs replacement.
Options
| Option | When it may fit | Limitations |
|---|---|---|
| Refinish the existing tub | Fits when the tub is solid, the shape still works and wear is surface-level. | Does not fix cracks, flex, entry height or an awkward layout. |
| Replace the tub | Fits when the tub is damaged, thin or a poor fit for the household. | Involves removal, plumbing connections and nearby wall work. |
| Convert to a shower | Fits when the household rarely soaks and would rather have a shower. | Removes the tub, which may matter for families or resale plans. |

Bathtub refinishing means cleaning, repairing and recoating the surface of a tub that stays in place.

Bathtub replacement removes your current tub and installs a new alcove, drop-in or freestanding model, usually in the same general location.

A tub-to-shower conversion takes out an existing bathtub, prepares the opening and installs a shower in its place.
Guides
Wear shows as dullness, roughness or faded color across the surface. Damage includes cracks, chips through the surface, flexing underfoot or water getting through. Damage usually narrows the options, so photos and notes help a provider assess it.
Many older tubs are solid under a worn surface and may be candidates for refinishing. Whether keeping one makes sense also depends on how it fits your household and the walls around it. A provider can weigh those points with you.
It depends on the tub material and the condition of earlier coatings. Some tubs take a second finish, while others are better replaced. A provider or refinishing specialist would need to look at the surface.
Over the years, the glossy layer can wear away, leaving a texture that holds residue. Cleaning products cannot rebuild that layer. Refinishing or replacement are the usual ways to change it.
Often the walls around a tub are disturbed during removal, so many homeowners update them at the same time. It is not always required. A provider can explain how the tub and walls connect in your bathroom.
