Tiling and grouting in Dubai: slip resistance, wet areas, joints and prices

Updated 17 October 2026. Every rule in this guide links to its official source at the end of the page.

Key facts

• Wet floors: smooth, hard, non-absorbent, non-slip; 100 mm non-absorbent base up the walls (DBC B.8.1.2).
• Wet walls: within 600 mm of fixtures, non-absorbent to 1,200 mm; showers and baths to 1,800 mm above the drain.
• Slip resistance: PTV 15 to 35 indoor dry, 35 to 45 outdoor and wet, 45+ for pools, showers and pavements (Table C.19).
• Proof: suppliers must give PTV data, or the tile is laboratory tested before acceptance.
• Accessible routes: avoid rounded-edge tiles and excessive joints; level changes over 13 mm ramped.
• Prices: tiling from AED 100/m², large format from AED 140/m², grouting from AED 35/m² (rate card, excluding VAT).

Why tiling has rules

Tiles are the standard finish for Dubai's bathrooms, kitchens, balconies, entrances, pool decks and many living areas, because they are hard, cleanable and suit the climate. But a tile floor is also a slip surface, a wet room's first line of defence against water, and in some buildings part of the food hygiene or accessibility rules. The Dubai Building Code therefore sets rules for sanitary finishes, slip resistance, accessible floor surfaces and food premises, and tiling done without them can lead to slips, leaks into the flat below, and failed inspections.

Bathrooms and wet areas: finish heights

Section B.8.1.2 of the Dubai Building Code sets requirements for walls, floors and partitions in sanitary facilities:

As guidance, tiles are a common way to meet these rules, but only if grout and joints are also sound: a tiled wall with cracked grout is no longer moisture-proof. Full-height tiling in showers, and tiling behind basins and WCs to at least the code heights, protects the gypsum or blockwork behind.

Slip resistance: the pendulum test

Section C.7.2.1.2 sets slip resistance for floor surfaces, measured by the pendulum test value (PTV) under BS EN 13036-4:

Inclined surfaces have their own, higher values in the same table. The code requires wet areas such as toilets and swimming pools to have non-slippery floors, PTVs to account for both shod and barefoot users, and product providers to supply slip resistance data in PTV units; if the data are not provided, the material should be tested in a laboratory before it is accepted. As guidance, glossy tiles that look good in a showroom may fall well below wet-area values, so asking for the PTV figure before buying avoids replacing a floor later.

Choosing tiles for each area

As guidance, porcelain tiles absorb very little water and suit most Dubai floors, while some natural stones are porous and need sealing in wet areas. Large-format tiles look seamless but need very flat substrates and full adhesive coverage.

Waterproofing before tiling

As guidance, tiles and grout are not waterproof on their own: water passes through grout joints and cracks into the screed below, and in apartments it then shows up in the ceiling of the flat underneath. Bathrooms, showers, balconies, kitchens around sinks and any floor that gets wet need a waterproofing membrane under the tiles, turned up the walls and sealed around drains and pipes, and tested before tiling. The Dubai Building Code requires horizontal surfaces in the envelope, such as balconies and terraces, to be jointless and impermeable, to have sealed joints, or to have overlapping joints that shed water. Power Zone's waterproofing guide covers membranes, flood tests and wet areas in detail.

Falls to drains

As guidance, wet floors must fall towards drains so water does not pool, and pools of standing water become slip hazards and leak paths. Falls are set in the screed before tiling, not by thick adhesive, and shower floors need falls steep enough to clear water quickly while keeping slip resistance. The code's accessibility rules limit changes in level: up to 13 mm with a maximum 25% bevel, and changes greater than 13 mm ramped, which matters at shower thresholds in accessible bathrooms. Drain grates with long openings must be laid with openings perpendicular to the direction of travel.

Substrate, adhesive and full bedding

As guidance, a common cause of hollow-sounding and cracked tiles is poor bedding: dabs of adhesive or incomplete coverage leave voids that crack under load. Tiles should be fixed with the right adhesive for the tile and substrate, with full coverage, especially for large tiles, floors with heavy traffic, and wet areas. Substrates must be sound, flat, clean and cured. The Dubai Building Code requires adhesives and sealants to stay within Dubai Central Laboratory VOC limits with certified materials, which applies to tile adhesives and sealants used indoors.

Movement joints and heat

As guidance, tiles, screeds and structures expand and contract with Dubai's heat, especially on balconies, terraces, roofs and near large glass areas. Without movement joints at perimeters, changes of plane and at intervals across large areas, tiles can tent, lift or crack. Joints are filled with flexible sealant rather than grout, and should line up with joints in the structure. The code requires the envelope to accommodate movement from service temperatures, and the same principle applies to tiling on exposed surfaces.

Grout and silicone

As guidance, grout fills joints and supports tile edges, but cement grout is porous and in showers and kitchens it stains, cracks and grows mould over time, while silicone at corners, edges, around baths, trays and basins allows movement and must be renewed when it peels or blackens. Epoxy grouts resist stains and water better in wet and food areas. Dubai Municipality's mould guideline identifies moisture as the root cause of mould, so dark, mouldy grout can point to a ventilation or leak problem as well as a cleaning one, and Power Zone's mold removal guide covers that.

Kitchens and food businesses

For food establishments, the code requires kitchen floors, walls and ceilings to be smooth, non-absorbent, non-combustible, non-toxic, crack-free and easily cleaned; floors to be hard-surfaced, non-absorbent and drained, built with waterproof, non-absorbent washable materials without fissures or crevices; and wall finishes to be smooth, waterproof, resistant to fracture, light-coloured and readily cleanable, in line with Dubai Municipality's General Conditions for Licensing of Food Establishments. As guidance, this points to fully bedded, non-slip, non-absorbent tiles with epoxy grout, coved skirting at wall junctions and floor drains with correct falls. Power Zone's kitchen exhaust and grease trap guide covers the other kitchen rules.

Balconies, terraces and outdoor paving

As guidance, outdoor tiling in Dubai faces sun, heat and occasional heavy rain, so it needs outdoor-rated, slip-resistant tiles, waterproofing beneath on balconies and roofs, falls away from doors, and movement joints. The code requires at least half of a development's hardscape to have a solar reflectance index of at least 33, use open-grid paving, or be shaded, which affects the choice of colour and finish for outdoor paving. In jointly owned buildings, balcony waterproofing and drainage can involve common parts, so check before major works. Power Zone's landscaping guide covers paving and drainage outdoors.

Pool surrounds

The code requires swimming pool areas to have non-slippery floors, with a PTV of 45 or more, accounting for barefoot users. As guidance, pool surround tiles also need resistance to pool chemicals, falls away from the pool to deck drains, and movement joints at the coping. Power Zone's pool maintenance guide covers pool safety and water treatment.

Accessible routes and level changes

Section C.7.2.1 requires floor surfaces on accessible routes to be firm, smooth and stable, and says tiles with rounded edges and excessive joints should not be used on accessible routes, to prevent wheel vibration, tripping and noise. Changes in level up to 13 mm need a maximum 25% bevel, and larger changes need a ramp. As guidance, this matters at shower entries, balcony thresholds and shop entrances, where flush, level-access tiling helps wheelchair users, older people and anyone carrying loads.

Cutting and grinding safely

Dubai Municipality's construction safety guide warns that dust containing silica particles can cause severe health effects (silicosis) and requires suitable respiratory protection for exposed workers, with eye and hearing protection for grinding machines and permissible noise exposure starting at 85 dBA for 8 hours a day. As guidance, tile cutting and grinding in occupied homes should use wet cutting or dust extraction, be done away from living areas where possible, with AC returns sealed so dust does not enter the ducts, as Power Zone's duct cleaning guide explains.

The tiling process step by step

1. Survey the area: substrate, levels, moisture, existing leaks and services under the floor.
2. Select tiles for each area by slip resistance (PTV data), absorption, size and use.
3. Prepare the substrate: remove old finishes where needed, repair, level and form falls to drains.
4. Waterproof wet areas, turning the membrane up walls and sealing drains and pipes, then flood-test.
5. Set out the tile layout and movement joint positions.
6. Fix tiles with the right adhesive and full coverage.
7. Grout joints and fill movement joints and junctions with flexible sealant.
8. Clean, inspect and hand over with tile data, PTV values and care instructions.

Natural stone and marble

As guidance, marble and other natural stones are popular in Dubai villas and lobbies but behave differently from porcelain: many are porous and need sealing, marble is etched by acids such as lemon juice and some cleaners, and polished stone can be slippery when wet. In wet areas and entrances, the code's slip resistance values still apply, so polished marble may need a honed or treated finish there. Power Zone's floor polishing guide covers grinding, polishing and slip resistance for stone.

Large-format tiles

As guidance, large-format tiles give few joints and a modern look but need a very flat substrate, full adhesive coverage, careful handling, and levelling systems to avoid lippage between tiles. They also show substrate movement more readily, so movement joints and a sound screed matter even more. Power Zone's rate card prices large-format tile installation separately from standard tiles for this reason.

Tiling over existing tiles

As guidance, tiling over old tiles can save removal time where the old tiles are sound, firmly bonded and flat, and where the extra height does not create trip hazards, block doors or break the code's 13 mm level-change limit at thresholds. It is not suitable over hollow or cracked tiles, failed waterproofing, or in wet areas where the membrane must be renewed. Removal is priced on Power Zone's rate card from AED 40 per m².

Car parks, garages and service areas

For car parks, the code requires floor surfaces to be non-absorbent, non-combustible, graded and equipped with drainage in line with the fire code. As guidance, garages and service areas therefore need hard-wearing, non-absorbent finishes with falls to drains, and oil-resistant grout and sealants where vehicles park.

Services under tiled floors

As guidance, water and drainage pipes often run under bathroom and kitchen screeds, so a leak there can show first as damp grout, loose tiles or stains below. Before retiling, it pays to pressure-test hidden pipes and check drains, and to record pipe routes so future works avoid drilling into them. Power Zone's plumbing guide covers leak detection.

Cleaning and caring for tiles

As guidance, tiles need little care if grout and sealant are kept sound: regular cleaning with neutral cleaners, prompt wiping of spills on stone, ventilation in bathrooms so grout dries, and resealing of porous stone and cement grout as the manufacturer recommends. Dubai Municipality's indoor air quality guideline lists cleansers, polishes and waxes among sources of volatile organic compounds, so cleaning products should be used as directed, with ventilation, and not mixed. Power Zone's deep cleaning guide covers safe cleaning in homes.

Rentals, move-out and who pays

Under Law No. 26 of 2007, the landlord is responsible for maintenance and repairing defects under Article 16 unless the lease says otherwise, and the tenant returns the property in the condition received except for ordinary wear and tear under Article 21; Article 19 bars tenants from making changes without permission and licences. As guidance, worn grout and aged silicone are normally maintenance items, while cracked tiles from impact are damage; dated photos at move-in and move-out help settle the difference.

Villas and holiday homes

As guidance, villas combine indoor tiling, bathrooms, kitchens, balconies, roof terraces and pool decks, each with different slip resistance and waterproofing needs, and roof and balcony tiling over living spaces is where leaks show first. Holiday homes see heavy use of bathrooms and pools, so annual checks of grout, silicone and drains, and quick replacement of cracked tiles, protect both guests and the property. Power Zone's villa maintenance guide sets out a yearly plan.

Inspection checklist

Common mistakes

Records to keep

• Tile product names, batches and PTV data for each area.
• Waterproofing product data and flood test records for wet areas.
• Adhesive, grout and sealant products used.
• Spare tiles from the same batch for future repairs.
• Photos of pipes and drains before screeding and tiling.

Signs of good tiling

• No hollow sound when tiles are tapped.
• Straight, even joints with no lippage between tiles.
• Water runs to the drain with no pooling.
• Clean, continuous silicone at corners, fixtures and edges.
• Movement joints where floors meet walls and across larger areas.
• No stains in the ceiling below after a year of use.

Walk-in showers and linear drains

As guidance, walk-in and level-access showers help accessibility, but they combine several rules: the floor must reach PTV 45 or more, walls around the shower must be finished non-absorbent to at least 1,800 mm above the drain outlet, level changes at the entry must stay within the code's 13 mm and 25% bevel limit or be ramped, and drain grates with long openings must run perpendicular to the direction of travel. Waterproofing must continue under the whole wet zone and beyond the shower area where water splashes.

Kitchen splashbacks and worktop junctions

As guidance, kitchen walls behind sinks and hobs take splashes, grease and heat, so splashbacks should be non-absorbent and easy to clean, with silicone at the junction with worktops rather than grout, which cracks as worktops move. In food businesses, the code's requirements for smooth, waterproof, light-coloured, readily cleanable walls apply to the whole kitchen, not just splashbacks.

Repair or retile?

Hotels, clinics and schools

As guidance, public and commercial buildings add higher traffic and stricter hygiene: entrances and corridors need durable, slip-resistant tiles to the code's values, accessible routes should avoid rounded-edge tiles and wide joints, toilets need the code's wall and floor finish heights, and food areas need non-absorbent, crack-free surfaces. Phasing work out of hours and keeping wet floors cordoned off until dry reduces slip risk for occupants.

Curing time before use

As guidance, adhesives and grouts need curing time before foot traffic, wetting or heavy loads, as set by the manufacturer, and Dubai's heat can speed surface drying while the bed beneath is still curing. Wet areas should not be used until grout and sealant have cured, and large-format floors may need longer before furniture is moved back. Agreeing a handover date that respects curing times avoids cracked joints in the first weeks.

Mosaics, feature walls and stone cladding

As guidance, mosaics and feature walls add detail but multiply grout joints, which need careful sealing in wet areas. Heavy stone or large tiles on walls need adhesives and fixings rated for their weight, and exterior wall cladding is part of the building envelope, which the code requires to be securely fixed, durable and not to detach. Power Zone's glass and aluminium guide explains the envelope's structural rules.

Leaks to the apartment below

As guidance, a stain in the ceiling under a bathroom or balcony is often the first sign that grout, silicone or waterproofing above has failed. The fix starts upstairs: find whether water comes from the shower, the floor drain, a pipe or the balcony, then repair the waterproofing rather than only regrouting. In jointly owned buildings, leaks involving common pipes or the building envelope may fall to the owners association under Law No. 6 of 2019, while leaks from a unit's own bathroom are usually that unit's responsibility, so documenting the source with photos and tests helps settle who repairs what. Power Zone's gypsum ceiling guide covers repairing the damaged ceiling.

Grout colour, joint width and appearance

As guidance, joint width depends on tile type and size: rectified tiles allow narrow joints, while handmade or calibrated tiles need wider joints to absorb size differences. Light grout shows dirt in kitchens and showers, darker or epoxy grout hides it better, and grout should be the same batch across a floor to avoid patchy colour. On accessible routes, the code's caution against excessive joints favours narrow, flush joints.

Before buying tiles: quick checks

• PTV value for each wet, outdoor or sloped area, from the supplier's data.
• Water absorption and suitability for floors, walls, indoor or outdoor use.
• Size tolerance and whether tiles are rectified.
• Stain and chemical resistance for kitchens and pool areas.
• Extra stock from the same batch for cuts and future repairs, agreed with the installer for the layout.

As guidance, complex layouts, diagonal patterns and large tiles produce more offcuts, so the installer should estimate the extra quantity from the actual layout.

Outdoor heat and paving colour

The code requires at least half of a development's hardscape to have a solar reflectance index of at least 33, use open-grid paving, or be shaded by vegetation, high-reflectance shading or solar panels. As guidance, light-coloured outdoor tiles stay cooler underfoot around pools and terraces, which also matters for barefoot users, while dark tiles in full sun can become uncomfortably hot.

Tiling in occupied homes

As guidance, retiling a bathroom or kitchen while people live at home works best when planned: one bathroom at a time so another stays usable, dust controlled with wet cutting and extraction, AC returns sealed in the work area, and noisy removal agreed with building management. Dubai Municipality's indoor air quality guideline asks for renovated areas to be isolated from occupied zones, which applies to tiling as much as to painting. Waste tiles and bags should leave the building daily through the agreed route.

Tiling and accessibility at home

As guidance, families planning for older relatives or wheelchair users can use tiling to make homes safer: slip-resistant floors in bathrooms and kitchens, level shower entries within the code's 13 mm limit, contrasting colours at steps and edges, and firm, stable surfaces without wide joints along walking routes, as the code recommends for accessible routes. Grab rails need solid fixing behind tiles, which is easiest to plan before tiling.

Pools and water features

As guidance, tiles inside pools and fountains are permanently wet and exposed to treated water, so they need pool-rated tiles, adhesives and grout, careful jointing around fittings, and regular checks for loose or sharp tiles that can injure swimmers. Pool decks and surrounds follow the code's PTV of 45 or more. Loose or missing pool tiles should be repaired promptly, often with the pool partly drained, as Power Zone's pool maintenance guide explains.

Frequently asked questions

What slip resistance do bathroom floors need in Dubai?

Wet areas need a pendulum test value of 35 to 45 for level floors and 45 or more in showers, under Table C.19 of the Dubai Building Code.

What is PTV?

The pendulum test value under BS EN 13036-4, which the Dubai Building Code uses to set slip resistance for floors.

How high must bathroom wall tiles go?

Walls within 600 mm of fixtures need a non-absorbent finish to at least 1,200 mm, and showers and baths to at least 1,800 mm above the drain outlet.

Do bathroom floors need a skirting?

Yes. Suppliers must give PTV data; if not provided, the material should be laboratory tested before it is accepted.

What PTV do pool surrounds need?

45 or more, accounting for barefoot users, under Table C.19.

Are tiles waterproof?

As guidance, no; tiles and grout let water through, so wet areas need a waterproofing membrane underneath.

Why are my tiles hollow?

As guidance, often incomplete adhesive coverage; hollow tiles that crack or move should be removed and refixed with full bedding.

Why are my tiles lifting?

As guidance, often heat expansion without movement joints, or poor adhesion; reset with joints where needed.

How much does tiling cost per m² in Dubai?

Power Zone's rate card lists floor tiling from AED 100 per m², wall tiling from AED 110 and large format from AED 140, excluding VAT.

How much does bathroom regrouting cost in Dubai?

From AED 250 per bathroom, with grouting from AED 35 per m² and silicone from AED 30 per metre, excluding VAT.

What floors do food businesses need?

Can tiles with rounded edges be used on accessible routes?

The code says tiles with rounded edges and excessive joints should not be used on accessible routes.

Is tile cutting dust dangerous?

Dubai Municipality warns that silica dust can cause silicosis and requires suitable respiratory protection for exposed workers.

Can I regrout instead of retiling?

As guidance, often yes if the tiles are sound and well bonded; regrouting and resealing restore the joints.

Can new tiles be laid over old tiles?

As guidance, sometimes, if the old tiles are sound and flat and the extra height respects thresholds; not over hollow tiles or failed waterproofing.

Is polished marble allowed in wet areas?

The code's wet-area slip resistance still applies, so polished stone may need a honed or treated finish there.

What floors do car parks need?

Non-absorbent, non-combustible, graded floors with drainage, under the Dubai Building Code.

Who pays to regrout a rented bathroom?

As guidance, worn grout is normally maintenance, the landlord's under Article 16 of Law No. 26 of 2007 unless the lease differs; impact damage is the tenant's.

Should I keep spare tiles?

As guidance, yes, from the same batch, so repairs match in colour and size.

Can cleaning products affect indoor air?

Yes. Dubai Municipality lists cleansers, polishes and waxes among VOC sources; use them as directed with ventilation.
