Shower Stone
Restoration

Professional cleaning, honing, polishing, and sealing for natural stone shower walls, floors, and surrounds throughout North Idaho.

Restore Your Shower
Without Replacing It

Natural stone showers are among the most demanding environments for stone — constant moisture, soap, and mineral-rich water create conditions that accelerate deterioration. What looks like permanent damage is usually a combination of problems that each require a specific approach.

Soap scum and mineral deposits are surface contaminants — they sit on and within the stone's pores and require professional deep cleaning with appropriate stone-safe chemistry to remove. This is not something household cleaners can fully address, and the wrong products can accelerate damage.

Etching — the dull, rough marks left when acids react with calcium-based stone — is a different problem entirely. It requires mechanical restoration through honing to remove the damaged layer and restore a consistent finish. Cleaning alone cannot remove etching.

Grout discoloration, failing silicone, and worn sealer compound the problem over time. We address each element of the shower as a system — cleaning, restoring the stone surface, and sealing properly — so the result lasts.

How We Do It

Our Restoration Process

01 — Evaluate
Surface Assessment
We identify the stone type, the nature of the buildup, any etching or scratching, the condition of the grout and silicone, and the state of the sealer. Showers require assessing multiple elements as a system before any work begins.
02 — Clean
Deep Cleaning
We use pH-neutral, stone-safe cleaners to remove soap scum, mineral deposits, biological growth, and contaminants from the stone surface and grout lines. This step must come before honing — you cannot polish over buildup.
Cleaning removes surface and subsurface contaminants. It does not remove etching or scratches.
03 — Hone & Polish
Honing & Polishing
Where the stone surface has been etched, scratched, or worn, we use diamond abrasive pads to remove the damaged layer and restore the correct finish — whether matte, honed, or polished. Shower stone is typically maintained at a honed finish for safety and aesthetics.
Honing and polishing restore the stone surface. This is how etching and scratches are corrected.
04 — Seal
Professional Sealing
We apply a penetrating impregnating sealer formulated for wet environments — protecting the stone from moisture penetration and reducing future mineral and soap buildup. Proper sealing in a shower is critical given the constant exposure to water. Sealing protects against staining, not acid etching.
In a shower environment, re-sealing more frequently than other stone surfaces is recommended.
Stone Types

Materials We Work With

Stone showers require material-specific care. Each stone behaves differently in a wet environment — here is what you need to know about yours.

Marble
Calcium-based · Soft
Beautiful but highly reactive to acids. Soap, shampoo, and body wash residue etches marble over time. Requires careful honing to restore, and diligent sealing and pH-neutral cleaning to maintain.
Travertine
Calcium-based · Soft–Med
Porous and prone to filling its natural voids with mineral deposits and soap. Requires void filling, deep cleaning, and sealing. Very common in shower floors and wall surrounds.
Limestone
Calcium-based · Soft
Similar to marble in vulnerability. Etches easily in wet environments. Requires the same careful honing, polishing, and sealing protocol with attention to product chemistry.
Slate
Silica-based · Medium
More resistant to etching than calcium-based stones. Its naturally cleft texture traps soap and mineral deposits. Deep cleaning and sealing restore its rich, dark appearance.
Granite
Silica-based · Hard
Durable and acid-resistant. In showers, granite primarily suffers from mineral buildup and sealer failure over time. Deep cleaning and re-sealing typically restores it fully.

Signs Your Shower Stone
Needs Attention

White or Grey Film That Won't Clean Off

A persistent hazy film is typically a combination of soap scum and hard water mineral deposits — calcium and magnesium from your water supply bonded to the stone surface. Standard cleaning products cannot fully remove this. Professional deep cleaning with appropriate stone chemistry is required.

Dull or Rough Stone Surface

Stone that was once smooth or polished but now feels rough or looks uneven has been etched — particularly common on marble, travertine, and limestone shower walls. This is physical damage to the stone surface caused by acidic products and requires honing to correct.

Dark or Discolored Grout

Grout discoloration in showers is caused by moisture, soap, and biological growth penetrating unsealed or deteriorating grout. Professional cleaning addresses biological growth and buildup; resealing grout lines prevents recurrence.

Water Soaking into the Stone

When water is absorbed by the stone rather than beading on the surface, the sealer has failed. In a shower environment this is particularly problematic — water penetration leads to staining, biological growth behind the surface, and potential substrate damage over time.

Failing or Discolored Silicone

Silicone at the base of the shower, corners, and transitions deteriorates over time — discoloring, cracking, and eventually allowing water behind the stone. Failing silicone is a maintenance item we address as part of shower restoration.

Considering Replacement

Stone shower replacement is a major renovation — typically $5,000 to $20,000 or more. Before committing to that, call us. The majority of stone showers that appear beyond repair can be fully restored for a fraction of that cost.

Questions

Frequently Asked

The white or grey film is a combination of soap scum — residue from soap, shampoo, and conditioner — and hard water mineral deposits, primarily calcium and magnesium. These bond strongly to the stone surface and cannot be removed with household cleaners. Professional deep cleaning with stone-safe chemistry removes this buildup without damaging the stone. In most cases the film can be fully removed, restoring the stone's natural appearance.
Yes. Etching on marble, travertine, and limestone shower surfaces is removed through honing — a mechanical process using diamond abrasive pads that removes the damaged surface layer and restores a consistent finish. The extent of the damage determines how aggressive the honing needs to be, but in most cases etching is fully correctable. We assess the surface first and give you an honest expectation before any work begins.
A typical shower restoration takes between 3 and 6 hours depending on the size of the shower, the extent of the damage, and whether grout cleaning and silicone work are included. We'll give you an accurate estimate during assessment. The shower needs to remain dry for 24 hours after sealing for the sealer to cure fully.
Three things make the biggest difference: use a pH-neutral stone-safe cleaner rather than general bathroom cleaners, squeegee the walls after each shower to reduce mineral deposit formation, and avoid acidic products entirely on calcium-based stone. We'll give you specific care instructions for your stone type at the end of every job. A maintenance plan with annual re-sealing significantly extends the time between full restorations.
No. This is an important distinction. Sealers are penetrating impregnators that protect against liquid absorption and staining — they do not create a surface coating and do not prevent acid etching. Acidic products will still etch calcium-based stone whether it is sealed or not. Sealing is essential for protecting against staining and moisture penetration in a shower environment, but it is not a substitute for using appropriate products and avoiding acids on the stone.
Shower stone requires more frequent re-sealing than other stone surfaces due to the constant exposure to water. As a general guideline, most shower stone benefits from re-sealing every 1 to 2 years. The simple water test tells you when it's time — if water soaks in rather than beading on the surface, re-sealing is needed. Our maintenance plans include periodic re-sealing visits to keep your shower stone protected year-round.
Because every stone surface is different, pricing depends on the stone type, current condition, access, square footage, and the level of restoration needed. In many cases, professional restoration is significantly less than replacement — often roughly one-third to one-half the cost of replacing the stone, depending on the project. We provide an honest written quote after the free in-home assessment so you know exactly what to expect before any work begins.
Yes. The restoration process — deep cleaning, grout treatment, sealing, and where needed regrouting or caulk replacement — applies to porcelain and ceramic tile showers just as it does to natural stone. We work with every shower material and treat each based on what it needs.

Common Questions

Questions About
Stone & Tile Showers

That dull filmy look is almost always soap scum buildup combined with hard water mineral deposits, and on calcium-based stones like travertine or marble it can also be light etching from acidic shower cleaners. North Idaho's water is mineral-rich, so calcium deposits accumulate fast on shower surfaces. Regular cleaners can't dissolve mineral buildup — and acidic cleaners actually make stone worse by etching the surface. Professional restoration removes the buildup, restores the original finish, and reseals everything correctly.
If the silicone is discolored, cracked, peeling, or moldy, yes — and replacing it is part of every professional shower restoration we do. Old silicone harbors mold spores that can't be cleaned out. We remove all old caulking, clean the substrate completely, and reapply premium silicone that's rated for wet environments. Replacing silicone every 5 to 8 years is normal even with good maintenance.
Three things solve almost all shower mold issues. First — squeegee the walls and glass after every shower. Most mold problems start with water sitting on surfaces. Second — make sure the bathroom has good ventilation. Run the fan during and for 20 minutes after every shower. Third — keep the stone properly sealed. A well-sealed stone surface gives mold far less to hold onto. For showers with existing mold, professional deep cleaning removes it completely before sealing.
In almost every case it can be restored. Natural stone is a permanent material — the surface gets damaged but the stone itself is fine. We hone away the damaged surface layer and polish to restore the original finish. Even severely worn stone showers come back beautifully. Replacement is rarely necessary unless there's a structural problem with the substrate behind the tile.
Yes — and this matters more than most people realize. Never use anything acidic on natural stone. That means no vinegar, no CLR, no Lime-A-Way, no Tilex, no Lysol bathroom cleaner, no citrus-based products, and no magic erasers on polished marble or travertine. These will etch the stone surface permanently. Use only pH-neutral stone-safe cleaners. We provide a care guide after every restoration with specific brands that are safe for your particular stone.
Most residential stone showers are completed in a single day, often in 4 to 6 hours. Larger or more damaged showers may take a day and a half. We work efficiently and clean up completely. You'll typically be able to use the shower again 24 hours after we finish, once the sealer has fully cured. We give you an accurate time estimate during the free in-home assessment.
