Condition of the substrate
The backing board or wall behind the surround needs to be dry and solid. Soft or damp areas usually have to be fixed before any new finish.
Shower walls
Shower walls carry the look of the whole bathroom. When panels crack or tile loosens, the concern is what may sit behind them as much as how they look.
Short answer
A worn or damaged shower surround can usually be replaced with tile, solid panels or a fitted liner system. Before choosing, the wall behind it needs checking, because loose tile or cracked panels may have let water reach the substrate. Sound walls give more options, while damaged backing must be addressed first. A provider assesses this in person and explains each choice.

Considerations
The backing board or wall behind the surround needs to be dry and solid. Soft or damp areas usually have to be fixed before any new finish.
Tile offers many looks but has grout lines. Panels have fewer seams. Each has different cleaning and installation needs.
The surround meets the tub or shower base at a seam that must stay watertight. A mismatched pairing can cause trouble.
In a humid climate like South Florida's, good ventilation helps any surround stay in better condition.
Safe observations
A replacement project fits when the surround is cracked, tiles are loose in several places, or the walls behind may have absorbed water. It also fits when you want a different look and the base or tub is staying.
Shower surround replacement focuses on the walls, while shower liner installation fits a new shell over a sound structure.
Options
| Option | When it may fit | Limitations |
|---|---|---|
| New tile surround | Sound walls and a homeowner who wants a custom look. | More seams and grout lines to keep clean, and substrate repair may be needed first. |
| Solid wall panels | A homeowner who wants fewer seams and simpler cleaning. | Fewer pattern choices than tile, and walls still need to be sound. |
| Fitted shower liner | A structurally sound surround that is worn on the surface. | Not a fix for wet or damaged walls behind the existing surface. |

Shower surround replacement removes the existing wall surround in a shower or tub-shower area and installs a new one, usually tile or panels.

Shower liner installation means fitting wall liners or surround panels in a shower or tub-shower area, either over sound existing walls or onto prepared walls after old material is removed.

Shower replacement removes an existing shower's base or pan, wall surround, valve and door or glass, then installs new components in the same footprint.
Guides
It means looking at the wall material behind the tile or panels to see whether it is dry and firm. A provider does this as part of the assessment, since a new surround over damaged backing can fail early.
Sometimes, if the tile and the wall behind it are sound and flat. If tiles are loose or the backing is damp, going over them may trap a problem. A provider will look first.
Panels usually have fewer seams, which can make cleaning simpler. Tile gives more design choice but adds grout lines to look after. Good ventilation and a squeegee after showers help either way in a humid climate.
Not necessarily. A surround can often be replaced around a sound tub or base. The seam where they meet needs careful sealing, and a provider will check the tub edge too.
A hollow sound can mean a tile has lost its bond with the wall. That may let water in behind it. It is worth noting for a provider rather than prying the tile off yourself.
