Bathroom & Wet Room Colored Sand Floor Coating
The coloured sand build specified for a room that gets wet and dries out every day: twelve fixed factory-blended colours, an open aggregate profile that a film of water cannot make smooth, and the water-control work placed where it belongs — falls, drain detail and upstand, not the coating.

Why buyers specify it
- Open coloured-sand texture under a gloss wear coat — the wet grip comes from the grain rather than from a classification we have not measured
- Twelve factory-blended colours shared with our interior build, so a bathroom matches the hallway outside it and a repeat order matches the first one
- Seamless wet zone with no grout grid to hold water and soil, which is the part of a tiled bathroom that actually goes black
- Carried up the wall line as a coved junction instead of stopped at a perimeter gap — the corner is where a wet room is cleaned to
- Continuous film that resists spills, splashes and a damp mop with a neutral cleaner; it is not a waterproofing layer and is not sold as one
- Supplied as a 20 kg pack, trowel-worked and back-rolled in one operation
Our interior coloured sand build, specified for a room that is wet most days: twelve fixed factory-blended colours, an open-aggregate film that a sheet of water cannot make smooth, worked at about 1.4 kg per square metre — with the water control stated where it actually sits, in the falls, the drain detail and the upstand, not in the coating.
Product overview
The same coloured sand system we fit indoors — coloured aggregate bound in epoxy and worked open so the grain reads across the surface, then sealed — specified here against a bathroom rather than a hallway. The material is identical to our interior coloured sand. What changes is what the room asks of it: it is wet most days, it is cleaned with detergent, people stand on it barefoot, and there is a drain set into it.
Coverage, thickness, pack size and finish are on the Technical Specs tab, and so is the list of figures we do not hold. Where a cell is empty it is empty because nobody has measured it, not because the data is confidential.
What a floor coating does not do about water
This is the sentence that decides whether the job is the right one, so it is here rather than in a footnote: a decorative resin floor is not a waterproofing layer. It is a continuous film, so it will not let a spilled shower through the surface the way an open grout grid does. It cannot hold back water travelling underneath it, it is not a tanking system, and it will not rescue a slab that was never given falls.
In a bathroom the water is controlled by four things that are all below or beside the floor: the fall to the drain, the detail at the drain itself, the upstand where the floor meets the wall, and the waterproofing membrane under the tile bed where one is required. Get those right and a coated floor is a very good finish over them. Get them wrong and the coating is the thing that fails first, quietly, and shows up last — usually on the ceiling of the room below.
So when you send us a wet room we ask about the substrate and the drainage first and the colour second. If the falls are wrong we will say the floor is not the job.
Grip when the floor is wet
The reason this build is specified in showers and bathrooms rather than a smooth self-levelling gloss is the aggregate. Working the grain open leaves a mechanical profile, and a thin film of water cannot make that profile smooth the way it does a polished surface. That is a description of the texture, not a slip certificate: we do not quote an R class for it and we do not describe any floor as slip-proof.
Two things follow that are worth planning around. An open profile holds grit and hair, so it needs vacuuming rather than just mopping. And the wear coat that gives the depth is the surface that gets walked on wet, so which topcoat is in the price is a decision we make with you at quotation, not a default.
Where it goes
- Bathroom and en-suite floors — including the zone immediately around a bath or a shower screen, where a grout line is the thing that goes black.
- Wet rooms and level-access showers — over a substrate that already has correct falls and a proper drain detail. The coating is the finish, not the fall.
- Laundry rooms, plant rooms and utility spaces — a seamless field with no joints to collect a leak that nobody sees until it has travelled.
- Cloakrooms and ground-floor WCs — the same argument in a smaller room.
- Splash zones up the wall — carried up as a coved junction rather than stopped at a perimeter line, because the corner is where a wet room is cleaned to and where water collects.
It is not a shower tray, a tanking layer, or a swimming pool finish, and it is not an external floor. For a terrace or a balcony the build is different in one specific way — the wear coat is chosen for weathering: see outdoor coloured sand.
Over existing tiles
Most bathroom floors in existing buildings are tile, and the reason people ask for a coating is to avoid taking the tile up. That works where the tile is bonded, flat and hollow-free, and can be abraded to a mechanical key. It does not work where the tile has debonded, where there is movement under the bed, or where a leak is already in the make-up — those are demolished or repaired, because a decorative film laid over a failed floor records the failure and holds the water in.
The dedicated page for that route, including what we ask you to test before ordering, is renovation over existing tiles.
Twelve fixed colours
The palette is the twelve factory-blended colours listed on this page, shared with our interior build so a bathroom matches the hallway outside it. The aggregate is blended into the pack rather than tinted on site, so a repeat order matches the first one.
This product is not part of the custom matching programme. Where a project needs a specific RAL or Pantone reference, that is a different build from our colour-matched range.
One honest note on the swatches: the images on this page are indicative renders, not photographed projects. Pale colours in a small, bright bathroom read lighter than the chip suggests, and Peach Red in particular sits closer to pink than to red once it is laid over a large area under white light.
What we do not publish
Hardness, abrasion loss, adhesion, slip classification, VOC and every cure timing are absent from the technical table because we have not tested this build. None of them is carried over from a similar product, and a supplier listing is not a test report.
That includes the one a bathroom actually needs: when it can take a shower. We set that per project from the primer and topcoat specified, and we put it in writing before the order rather than reading it off a marketing sheet.
The material here is the same as our interior coloured sand: coloured aggregate bound in epoxy, worked open so the grain reads across the surface, then sealed under a gloss wear coat. What changes is the room. A bathroom floor is wet and then dry, repeatedly; it is cleaned with detergent; it is walked on barefoot; it has a drain set into it and a junction with the wall where the water goes. Those are all specification questions rather than colour questions, and they are why this build is listed separately.
The sentence that decides whether the job is ours: a decorative resin floor is not a waterproofing layer. It is a continuous film, so surface water sits on it instead of soaking into a grout grid, and that is a real advantage over a tiled wet zone. It is not a tanking system, it holds nothing back from below, and it will not rescue a slab that was never given falls. In a bathroom the water is controlled by four things that sit below or beside the floor — the fall to the drain, the detail at the drain, the upstand at the wall line, and the membrane under the tile bed where one is required. Get those right and a coated floor is a very good finish over them. Get them wrong and the coating fails quietly and shows up last, usually on the ceiling of the room below.
The reason this build goes in a shower room at all is the aggregate. Working the grain open leaves a mechanical profile, and a thin film of water cannot make that profile smooth the way it does a polished surface — which is exactly what it does to a plain gloss self-levelling floor. That is a description of the texture, not a slip certificate: we publish no classification for it. Two practical consequences follow, and both belong in the plan rather than in a footnote. An open profile holds grit and hair, so the room needs vacuuming and not only mopping. And the wear coat is the layer that gets walked on wet and cleaned with detergent, so which clear is in the price is a decision we make with you at quotation.

Installation & cure data
| Coverage | 1.4 kg/m²Partner factory figure for the coloured sand coat on a normal concrete bed, mixed. Their usage table gives one rate per substrate against a 2 mm reference — 1.3 dense new concrete, 1.4 normal concrete, 1.6–1.8 rough or aged, 1.5 tile or terrazzo — so a floor coated over existing tile takes the 1.5 figure, and that build is on colored-sand-floor-over-existing-tiles |

Application sequence
Settle the water question firstBefore order
Confirm the fall to the drain, the condition of the drain detail, and whether there is a membrane under the existing tile bed. Where a bathroom has no fall and the slab below is somebody else's ceiling, that is the job and the coating is the finish over it.
Test what is already thereDay 1
Existing tile has to be bonded, flat and hollow-free, and abradable to a mechanical key. Tap-test the whole floor. Loose or debonded tile is lifted, because a decorative film laid over a failed bed records the failure and holds the water in.
Abrade, repair, vacuumDay 1
Scarify the glaze or diamond-grind the slab, fill cracks and level. A gloss film shows every ridge left in the preparation and every tile joint under it, so this is the step that decides the appearance.
Set the primer for the roomDay 1
Porosity and residual damp decide the primer and its rate. We specify it from the site information rather than from a fixed number, because the wrong choice here fails the whole build.
Work the coloured sand coat and cove the wall lineDay 2
One 20 kg pack at a time, gauged to roughly 1.4 kg/m², back-rolled to open the aggregate evenly. Taken up the wall as a coved junction rather than stopped at a perimeter line. Batch the room so a colour change is not visible in it.
Gloss wear coat, then keep water off itDay 3 onward
Applied once the sand coat has set. No shower, no mop and no standing water until the timing for the specific primer and wear coat in your quote has been confirmed — we set that per project rather than reading it off a sheet.
Field tips
- The coating is not the fall. Water that ponds will stay there and will find the perimeter of the film, so the gradient is settled before this build is quoted.
- Do not treat the coating as a tanking layer. Where the room needs a waterproof membrane it goes under the floor build, not rolled over the finished surface.
- Do not bridge a movement joint or a change of plane. Cover it with a flexible detail, or it will re-open as a crack in the film and water will go under it from there.
- Below grade, or on a slab that has never been tested for moisture, test the slab before anything else. This build is vapour-tolerant only as far as the primer makes it.
- A gloss film in a bathroom shows every dried puddle. Squeegee after use, or accept the mineral marks as part of the finish.
- The open profile holds grit and hair, so vacuum the room rather than only mopping it, and keep entry mats at the door — grit is what scratches a gloss floor.

Where this system works
Wet rooms and level-access showers
Over a substrate that already has correct falls and a proper drain detail. The coating is the finish, not the fall, and we ask about both before quoting.
Laundry rooms, plant rooms and utility spaces
A seamless field with no joints to collect a leak that nobody sees until it has travelled along a pipe run.
Cloakrooms and ground-floor WCs
The same argument in a smaller room: wipeable, dust-free, and no perimeter gap to clean out.
Splash zones up the wall
Carried up as a coved junction so the corner can be wiped rather than cleaned out of a gap where a tiled build would leave it.

After handover
- Vacuum or sweep first, then damp mop with a neutral cleaner. Grit sitting in an open profile is what scratches the film, and on a gloss floor the scratches show.
- Wipe or squeegee the standing water after a shower. That is not protecting a membrane — it is keeping soap and dissolved minerals out of the texture, where they build up a dull film.
- Keep the junction at the drain in view. If that detail opens, it is a water-control repair and not a coating repair, and it is cheaper while it is small.
- Re-coat the wear layer when the sheen goes dull in the traffic lane; the coloured sand body underneath normally never needs touching.
- Avoid solvent-based and acidic cleaners, including limescale removers on a gloss film — they dull it in patches that cannot be blended.
Frequently asked questions
Does this floor waterproof my bathroom?
No, and a page that says otherwise is selling you the wrong product. This is a continuous decorative film: surface water sits on it rather than soaking into a grout grid, but it is not a tanking layer and it does not hold water back from below. What protects the room underneath is the fall to the drain, the detail at the drain, the upstand at the wall and the membrane under the tile bed. Fix those first and we will happily quote the finish over the top.
Can it go over existing bathroom tiles?
Where the tile is bonded, flat and hollow-free, and can be abraded to a mechanical key — yes, and avoiding demolition is the usual commercial argument for it. Where the bed has debonded, where there is movement under the tile, or where a leak is already in the make-up, the floor is lifted or repaired instead, because a decorative film over a failed floor records the failure and holds the water in. We ask for a tap test of the whole area before quoting this route.
Is it slippery when wet?
The grip comes from the open aggregate rather than from a finish we have tested, which is why a coloured sand build is specified in showers at all — a thin film of water cannot make an open profile smooth the way it does a polished one. We publish no slip classification for it because we have not run the ramp test that would justify one. Describe the room and the fall risk and we will tell you how coarse to work the grain.
When can it be used as a shower?
Not from a number printed on a page. The data sheet that came with this batch states a fast surface-dry; the sheet behind our interior page gives a slower one for what is the same material. Neither is our test and the two disagree, so this page publishes no cure timings at all. We set the first-shower timing per project from the primer and wear coat actually quoted, and confirm it in writing before the order.
Is it mould-resistant?
We make no biocidal claim about it, because there is no test behind one. What is actually true is plainer and is the reason people choose it: there is no grout grid in the wet zone to hold water and soil, and a continuous film wipes clean. Keep the room ventilated and vacuum rather than only mop, and the open profile will not hold the grit and hair that a tiled corner does.
Can you match a specific RAL or Pantone colour?
Not on this product. The aggregate is blended at the factory into the pack rather than tinted on site, so the twelve listed colours are what is available. They are the same twelve as our interior build, which is what lets a bathroom match the hallway outside it. Colour matching is a different build from our colour-matched range.
Why are the technical figures missing?
Because we have not tested this build. Hardness, abrasion, bond, slip, VOC, cleaning resistance and every cure timing are absent rather than carried over from a similar product, and a supplier listing is not a test report. What we do publish — coverage, pack size, finish and colour count — is marked as partner factory data so you can see which figures are ours and which are theirs.
