Shower Tile and Grout Restoration

Shower restoration treats the whole enclosure rather than one surface: tile, grout lines, shower floor, glass, and the caulked joints where planes meet. It removes soap scum, mineral deposits and biological growth, renews the caulked joints, and seals what should be sealed. Everstone restores showers throughout Southwest Washington and the Portland metropolitan area.

Before and after

Travertine shower enclosure and hard water glass
Before and after: a shower corner with rust-colored staining across the tile and grout, cleaned back to even tile and pale grout
Mosaic shower floor with darkened grout
Before and after: a shower wall with a rust trail running below the valve, cleaned away to leave clean tile and grout
Red tiled shower floor with mineral deposits
Before and after: a shower wall hazed with soap film and a darkened corner joint, cleaned back to clear tile and a clean white joint
Glass block shower window with stained joints
Before and after: a brown tile shower bench and wall dulled by buildup, cleaned and sealed to an even finish

Why showers are the hardest surface in the house

A shower is a wet room that never fully dries. In this climate, ambient humidity means the walls stay damp between uses for most of the year, and grout is porous enough to hold that moisture for days. Three things happen as a result.

Grout turns black

What looks like dirt is usually biological growth in the pore structure of the grout, feeding on soap residue and body oils in a permanently damp material. Surface cleaners reach the top of it and leave the rest, which is why it returns within weeks.

Glass clouds over

Hard water leaves mineral deposits that bond to the glass surface. Soap scum builds on top. Past a certain point, household glass cleaner does nothing because the deposit is no longer sitting on the glass, it has etched into it.

Caulk and grout fail at the joints

Corners and the tub or pan line move. Where those joints were grouted rather than caulked, they crack, and water gets behind the tile.

What full shower restoration covers

Tile and grout deep cleaning

With high-temperature vapor, up to 330°F at the equipment

Glass restoration

Removing hard water film and soap scum

Re-caulking

Of change-of-plane joints: corners, wall-to-floor, and the tub or pan line

Waterproofing attention

At the joints where water gets behind tile

Sealing

Of grout and stone once the surfaces are clean and cured

Needing only part of this is common. We will scope what your shower actually requires and price accordingly.

Our process

1. Evaluation

Identify the tile and stone material, find where grout or caulk has failed, and check whether water has been getting behind the tile. Chemistry that is safe on porcelain will etch marble or travertine, so this step is not a formality.

2. Cleaning

Proprietary commercial-grade cleaners with high-temperature vapor, up to 330°F at the equipment. Heat and moisture lift soil out of grout without the scrubbing that erodes it.

3. Glass

Mineral deposit and soap scum removal from shower glass and doors.

4. Re-caulk

Movement joints get caulk, not grout. This is the step most commonly skipped, and it is the one that keeps water out from behind the tile.

5. Sealing and care

Clean, cured grout and stone are sealed. The first seven days matter most, so clean up spills immediately while the treatment cures.

We look at the tile, grout, glass and joints, tell you what it actually needs, and quote it. Free, and no obligation.

What the warranty covers here, stated plainly

Shower restoration involves several different kinds of work, and our five-year warranty does not cover all of them. Here is exactly where the line sits.

Covered

The sealer we apply to grout and stone carries a five-year limited warranty to the original purchaser against sealer failure: peeling, flaking, or excessively rapid wear.

Not covered

Labor. Caulking. Etching. Staining. Quartz. The sealing of glass.

On caulk specifically

Re-caulking is part of this service and caulk is excluded from the warranty. Caulk in a wet area is a consumable. It needs periodic replacement regardless of who applies it or how carefully, and no honest warranty covers it for five years. We are telling you this on the service page rather than in the exclusions list, because you should know it before you buy, not after.

Common questions

My grout turns black again a few weeks after I clean it. Why?

Because surface cleaning removes what is on top and leaves what is inside the grout. The growth continues in the pore structure and resurfaces. Deep cleaning followed by sealing addresses both parts of that.

Can cloudy shower glass actually be fixed?

In most cases, yes. Hard water deposits and soap scum come off with the right chemistry. Where the mineral has etched into the glass itself over years, there is a limit to what restoration reaches, and we will tell you which one you have before you book.

Do I need to regrout, or will cleaning do it?

Press the grout. If it is solid, cleaning will do it, and in almost all cases that is what we find. If it crumbles under light pressure, cleaning will not fix it and the grout needs replacing, which is not work we take on. We check this during the estimate and tell you which one you are looking at.

How long does the shower need to stay dry afterward?

24 hours before the shower is used again.

Is this cheaper than retiling the shower?

Substantially, in most cases. Retiling replaces tile that is usually still sound. Restoration starts at $549 and rises with the size of the shower, its condition and the material.

Do you work on natural stone showers?

Yes, including travertine and marble. Stone needs different chemistry than porcelain, which is why material identification comes first.
