Why Choose Us

Bathroom Stone Floor
Restoration Specialists -
London

Bathroom and wet room environments present unique challenges for natural stone floors. Constant moisture, cleaning chemicals, humidity and barefoot traffic accelerate etching, mould growth, grout deterioration and surface wear. Restoring stone in a bathroom requires not just polishing expertise but specific knowledge of anti-slip treatment, wet-area sealing and silicone joint maintenance.

Anti-Slip Treatment (PTV 0.40+)
We apply a micro-etching anti-slip treatment that creates micro-texture on the stone surface — invisible to the eye but raising the Pendulum Test Value (PTV) to above 0.40, meeting UK wet-floor safety standards.
Wet-Room Grade Sealing
Standard sealers are not sufficient for bathrooms and wet rooms. We apply a high-strength impregnating sealer designed for constant moisture exposure, preventing water ingress, mould and mineral staining.
Grout & Silicone Joint Replacement
Deteriorated, cracked or mouldy grout and silicone joints are a primary source of water ingress behind bathroom stone. We re-grout and replace silicone at floor/wall junctions as part of the restoration.
Mould & Limescale Removal
Hard water limescale, soap scum and biological mould growth are removed using pH-safe stone cleaners — alkaline for biological matter, specialist limescale remover that will not etch calcium carbonate.
Diamond Honing for Bathroom Finish
We recommend a honed (matt) or satin finish for bathroom floors — not high-gloss, which becomes dangerously slippery when wet. Diamond honing to 200–400 grit provides a safe, easy-clean surface.

How It Works

Our 8-Step Bathroom Stone Restoration Process

Bathroom stone restoration is more comprehensive than standard floor restoration — it must address moisture management, safety, grout condition and long-term wet-environment sealing.

01

Survey & Assessment

Assess stone type, etch severity, mould presence, grout/silicone condition, and anti-slip requirements. Free site visit.

02

Mould & Limescale Treatment

Specialist alkaline cleaner removes mould, soap scum and biological growth. Limescale removed with stone-safe acid-free specialist product.

03

Grout Removal & Replacement

Deteriorated or mouldy grout is removed and replaced with colour-matched waterproof grout. Joints raked clean before re-grouting.

04

Silicone Joint Replacement

Old silicone at floor/wall junctions removed fully and replaced with anti-mould bathroom-grade silicone — a primary route of water ingress if neglected.

05

Diamond Honing

Progressive diamond pads remove etch marks, scratches and surface damage. We work to 200–400 grit for a bathroom-appropriate honed finish.

06

Polishing to Agreed Finish

Fine diamond pads or crystallisation bring surface to honed or satin finish — we advise against mirror polish for wet floor safety reasons.

07

Anti-Slip Treatment

Micro-etching anti-slip treatment applied to raise PTV above 0.40 (wet floor safety standard). Invisible, does not alter appearance.

08

Wet-Area Impregnating Sealer

2-coat high-strength impregnating sealer applied and cured. Designed for continuous moisture exposure in bathroom and wet room environments.

The Full Picture

Bathroom Stone Floor Restoration London - Expert Guide

Natural stone bathroom floors — marble, travertine and limestone — are beautiful but require specific maintenance and periodic professional restoration. The wet environment, combined with cleaning products that are often acidic or bleach-based, accelerates surface damage faster than in dry-area stone floors. Most bathroom stone floors need professional attention every 3–7 years.

Most Common Bathroom Stone Problems

Etch marks and dull patches — bleach-based bathroom cleaners, acidic limescale removers and even natural shampoos and conditioners etch calcium carbonate stone. Marble is particularly vulnerable.
Black mould in grout lines — grout is porous and in a constant-moisture environment accumulates mould that cannot be removed by surface cleaning. Re-grouting with waterproof grout is the permanent solution.
Silicone joint failure — the silicone bead at the junction of floor and wall tiles is a primary water ingress point. When it fails, water tracks behind tiles and can cause significant structural damage over time.
Slippery polished surface — a high-gloss polished stone floor is potentially dangerous when wet. Anti-slip treatment raises safety without visible change to the surface.
Limescale and hard water staining — heavy limescale deposits on stone require specialist treatment. Standard limescale removers contain hydrochloric acid which will immediately etch marble and limestone.

Anti-Slip Treatment — What Is PTV?
The Pendulum Test Value (PTV) is the UK's standard measure of slip resistance for wet floors. A PTV above 0.36 is required for public spaces; we target above 0.40 for residential bathroom floors. Our anti-slip treatment creates micro-texture on the stone surface through a controlled chemical micro-etching process — it does not change the appearance, colour or feel of the stone, but makes it significantly safer underfoot in wet conditions. We can test the PTV before and after treatment at your request.

Bathroom Stone Care Between Restorations
Use pH-neutral stone cleaners only. Avoid all bleach-based, acidic or abrasive bathroom cleaners — they will etch and scratch the stone surface progressively. Dry the floor after each use where possible (particularly for marble) to slow sealer wear. Inspect silicone joints annually and replace if cracking or discolouring. Re-seal every 2–4 years in active bathrooms.

Stone Types

Marble, Travertine & Limestone Bathroom Floors

Each stone type has distinct characteristics that affect how we approach bathroom restoration — particularly around etch sensitivity, sealing and anti-slip treatment.

Marble Bathroom Floors

Marble is one of the most popular bathroom floor choices in London properties but is also one of the most etch-prone stones. Calcite reacts immediately with acid. We restore marble bathroom floors to honed or satin finish with anti-slip and wet-area sealing.

  • Etch mark removal by diamond honing
  • Crystallisation or satin finish
  • Mould and limescale treatment
  • Anti-slip treatment + impregnating seal

Anti-slip treatment + impregnating seal

Travertine’s natural pits are a particular concern in bathrooms — they trap mould and moisture. We clean and treat the pits, fill if required, hone, apply anti-slip and seal with a wet-strength impregnating sealer designed for bathrooms.

  • Pit cleaning and mould treatment
  • Epoxy hole filling if required
  • Diamond honing to bathroom finish
  • Anti-slip + wet-area impregnating seal

Limestone Bathroom Floors

Limestone in bathrooms is softer than marble and more porous, making proper sealing absolutely critical. We deep-clean, hone, apply anti-slip treatment and use a high-build impregnating sealer to protect the porous calcium carbonate structure.

  • Deep cleaning and stain extraction
  • Diamond honing — 120 to 400 grit
  • Anti-slip micro-etching treatment
  • High-build impregnating wet-area sealer

Common Questions

Bathroom Stone Restoration FAQ

Is anti-slip treatment safe on marble and travertine?

Yes — anti-slip micro-etching treatment is specifically formulated for natural stone bathroom floors. It creates an invisible micro-texture on the stone surface that significantly increases grip without altering the visual appearance, colour or reflectivity of the stone. The PTV (slip resistance value) is tested before and after application. It is compatible with marble, travertine and limestone.

Can you restore stone bathroom floors without removing the tiles?

Yes — in almost all cases. Our diamond honing, polishing and sealing process is done in situ, with the tiles on the floor. We only need to access the stone surface from above. Grout replacement is also done in situ — we rout out the old grout and regrout without lifting tiles. The only situation requiring tile removal is if there is significant water damage or substrate movement, which we would identify at the free site survey.

How do I remove black mould from marble bathroom grout?

Surface mould in grout can be reduced with alkaline cleaners (never bleach on stone), but once mould has penetrated into the grout body, surface treatment will not eliminate it permanently. The only long-term solution is grout removal and replacement with a waterproof grout — typically an epoxy grout for bathroom applications. We include grout assessment and replacement as part of our bathroom stone restoration service.

Why is my marble bathroom floor etching so quickly?

Bathroom environments are very aggressive for calcium carbonate stones. The most common causes are: (1) acidic bathroom cleaners and limescale removers — always use pH-neutral stone-specific cleaners; (2) shampoo and conditioner runoff, which can be acidic; (3) cleaning products containing citric acid or vinegar; (4) the absence of a sealer, which leaves the stone unprotected. We will restore the etch damage and provide you with a stone-safe maintenance programme after restoration.

How long does bathroom stone restoration take?

A full bathroom stone restoration (8-step process including grout replacement, silicone, honing, anti-slip, sealing) for a typical en-suite (8–15m²) takes 1–2 days. The sealer and silicone require 24 hours to cure before the bathroom can be used. We recommend booking a weekend or planning for 2 nights without the bathroom being in use.

Should I use polished or honed stone in a bathroom?

We recommend honed or satin finish for bathroom floors. Polished (high-gloss) stone is more visually striking but becomes very slippery when wet and shows etch marks more readily. Honed marble or travertine is easier to maintain, significantly safer in a wet environment, and can be brought to a satin sheen that still looks luxurious. For bathroom walls, polished stone is fine as safety is not an issue.
