LVT Flooring Thickness: 3mm to 8mm Complete Guide

LVT flooring thickness ranges from 3mm to 8mm and directly affects how durable, comfortable, and easy to install a Luxury Vinyl Tile floor is. 4mm and 5mm are the most popular LVT flooring thickness grades for homes across the United Kingdom, whilst 6mm and 8mm suit busy commercial spaces and high-traffic rooms.

Choosing the wrong LVT flooring thickness costs more in the long run. 3mm Luxury Vinyl Flooring wears out quickly in busy rooms, shows every bump in the floor underneath, and needs replacing within 3 to 5 years under heavy daily use. 6mm and 8mm Luxury Vinyl Tiles fitted over underfloor heating act like a blanket over the heating system, cutting efficiency by up to 15% and pushing energy bills up over time.

Thicker LVT flooring does not always mean better quality. A 4mm Luxury Vinyl Tile (LVT) flooring plank with a 20 mil wear layer outlasts a 6mm plank with a 6 mil wear layer in scratch resistance and daily surface wear. Wear layer thickness, core material quality, and backing layer stability matter more than total plank thickness when judging the quality of any Luxury Vinyl Flooring product.

What Is LVT Flooring Thickness?

Luxury Vinyl Tile (LVT) flooring thickness is the total depth of a plank or tile, measured in millimetres (mm) from the bottom backing layer to the top wear layer. UK Luxury Vinyl Flooring is classified into 4 standard thickness grades: 3mm, 4mm, 5mm, 6mm, and 8mm. 4mm and 6mm are the most widely installed thickness grades for residential Luxury Vinyl Tiles across the United Kingdom.

LVT flooring thickness directly determines 4 measurable properties.

• Durability: Thicker Luxury Vinyl Flooring planks resist denting and surface damage more effectively than thinner grades.
• Subfloor Tolerance: 6mm Luxury Vinyl Tiles tolerate up to 3mm of subfloor unevenness per 1.8 metres, compared to 1mm tolerance for 2mm grades.
• Underfoot Comfort: LVT flooring at 6mm and above provides measurably greater underfoot cushioning than 2mm or 4mm grades.
• Sound Insulation: 6mm–8mm Luxury Vinyl Tile (LVT) flooring reduces impact sound transmission by up to 19dB without a separate underlay.

What Are the Standard LVT Flooring Thickness Sizes in the UK?

 

The standard Luxury Vinyl Flooring thickness sizes in the UK are 2mm, 3mm, 4mm, 5mm, 6mm, and 8mm. 4mm and 5mm are the most popular LVT flooring thickness sizes for homes across the United Kingdom. The busier the room, the thicker the Luxury Vinyl Tile required.

The 6 standard LVT flooring thickness sizes and their best uses are:

• 2mm: Suits quiet rooms that do not get much foot traffic, like storage rooms and utility spaces. 2mm Luxury Vinyl Flooring needs a very smooth and flat floor underneath, as even the smallest bumps show through such a thin plank.
• 3mm: Suits rooms where the floor cannot be raised too high, such as doorways with very little space under the door frame. 3mm Luxury Vinyl Tile (LVT) flooring adds the least amount of height to a room, making it the top choice for renovations where doors and skirting boards stay fixed in place.
• 4mm: Suits everyday home rooms like bedrooms, living rooms, and hallways. 4mm Luxury Vinyl Flooring handles regular daily foot traffic well and does not need as much floor preparation underneath before fitting.
• 5mm: Suits busier home areas like kitchens and open-plan living spaces. 5mm Luxury Vinyl Tiles hide small bumps in the floor underneath and last longer than 2mm and 3mm grades in rooms with heavier daily use.
• 6mm: Suits high-traffic home rooms and light commercial spaces where the floor underneath is not perfectly flat. 6mm LVT flooring handles more unevenness underneath than thinner grades, saving time and money on floor preparation before fitting.
• 8mm: Suits busy commercial spaces where comfort underfoot, quietness, and handling an uneven floor underneath all matter. 8mm Luxury Vinyl Tile (LVT) flooring delivers the best performance of all standard UK thickness grades across every measurable property.

What Is the Best LVT Thickness for Every Room?

 

The best LVT flooring thickness for every room depends on how busy the room is, how flat the floor underneath is, and how much moisture the room gets. The 9 best Luxury Vinyl Tile thickness recommendations by room are:

• Living Room: 4mm LVT flooring suits living rooms that get a steady flow of people walking through every day. 4mm Luxury Vinyl Flooring handles regular family use well without needing a lot of floor preparation underneath before fitting.

• Bedroom: 3mm to 4mm Luxury Vinyl Flooring suits bedrooms that get the least amount of foot traffic of any room in a UK home. 4mm Luxury Vinyl Tiles provide enough protection and comfort underfoot for light daily use in a bedroom.
• Kitchen: 5mm Luxury Vinyl Tiles suit kitchens that get heavy daily use, frequent spills, and moisture exposure. 5mm LVT flooring also hides small bumps in the floor underneath that are common in older UK kitchens.
• Bathroom: 4mm to 5mm LVT flooring suits bathrooms that need a fully waterproof floor. 5mm Luxury Vinyl Flooring suits larger UK bathrooms where the floor underneath is uneven from old tiles being removed.

• Hallway: 5mm to 6mm Luxury Vinyl Tile (LVT) flooring suits hallways that get more foot traffic than any other room in a UK home. 6mm LVT flooring handles the heavy daily wear and uneven floors found in UK hallways better than thinner grades.
• Dining Room: 4mm to 5mm Luxury Vinyl Flooring suits dining rooms that get moderate foot traffic along with chairs and furniture being moved around daily. 5mm Luxury Vinyl Tiles resist dents from chair legs and furniture feet better than 3mm and 4mm grades.
• Kids Room: 5mm to 6mm Luxury Vinyl Tiles suit children’s rooms that get heavy and unpredictable use from playing, dropping toys, and frequent spills. 6mm LVT flooring handles knocks, impacts, and heavy use in an active play environment better than thinner grades.
• Home Office: 4mm to 5mm LVT flooring suits home offices that get moderate foot traffic combined with office chair castors rolling across the floor daily. 5mm Luxury Vinyl Flooring resists dents and surface wear from chair castors better than 3mm and 4mm grades.
• Commercial Space: 6mm to 8mm LVT flooring suits commercial spaces that get far more foot traffic than any residential room. 8mm Luxury Vinyl Tile (LVT) flooring delivers the best durability, quietness underfoot, and ability to handle uneven floors of all standard UK thickness grades.

How Does LVT Thickness Affect the Installation Method?

LVT flooring thickness determines which installation method suits a project best. The 3 main Luxury Vinyl Tile installation methods and their required thickness grades are:

• Click/Floating: 5mm and above LVT flooring suits the click floating method, where planks snap together and float freely over the subfloor without glue. Thicker Luxury Vinyl Tiles provide the rigidity needed to keep click joints from separating under daily foot traffic.
• Glue-Down: 2mm to 4mm Luxury Vinyl Flooring suits the glue-down method, where planks are bonded directly onto the subfloor using adhesive. Glue-down installation requires the smoothest and flattest subfloor of all 3 methods, as thin LVT flooring transfers every bump and dip beneath it directly to the surface.
• Loose Lay: 5mm and above Luxury Vinyl Tile (LVT) flooring suits the loose lay method, where planks sit in place using their own weight and a grippy backing, with no glue or click joints needed. Thicker Luxury Vinyl Tiles carry enough weight and stiffness to stay firmly in place without sliding or lifting at the edges.

How Does LVT Thickness Affect Durability?

Thicker LVT flooring lasts longer and handles more daily wear than thinner grades. Luxury Vinyl Tile (LVT) flooring thickness affects durability across 4 properties:

• Impact Resistance: 6mm and 8mm Luxury Vinyl Tiles resist dents and cracks from heavy knocks and dropped objects that visibly damage 2mm and 3mm grades.
• Indentation Resistance: 5mm and above LVT flooring resists permanent dents from heavy furniture and chair castors that leave visible marks on 2mm and 3mm Luxury Vinyl Flooring over time.
• Wear Layer Protection: A 20 mil wear layer on a 6mm Luxury Vinyl Tile lasts up to 5 times longer than a 6 mil wear layer on a 2mm grade in busy rooms.
• Subfloor Stress: Thicker LVT flooring spreads foot traffic weight more evenly across the subfloor, reducing the risk of surface cracking and plank joints coming apart over time.

Does LVT Flooring Need Underlay?

LVT flooring does not always need a separate underlay, as many Luxury Vinyl Tile products come with one already stuck to the bottom. Whether a separate underlay is needed depends on the LVT thickness grade and the installation method. 

• Pre-Attached Underlay: 5mm and above Luxury Vinyl Tiles commonly come with a foam or cork underlay already bonded to the bottom of the plank, adding 1mm to 2mm of extra cushioning for comfort and sound insulation without needing a separate layer underneath.
• Separate Underlay: 2mm, 3mm, and 4mm Luxury Vinyl Flooring without a pre-attached underlay needs a separate underlay of 1mm to 3mm thickness underneath. A 2mm underlay suits 4mm LVT flooring in home rooms, whilst a 3mm underlay suits 2mm and 3mm Luxury Vinyl Tiles where the floor underneath has small bumps and dips.
• Underlay Over Underfloor Heating: Luxury Vinyl Tile (LVT) flooring fitted over underfloor heating needs a combined total thickness of no more than 18mm, including both the LVT and the underlay together. A 1mm to 2mm underlay suits LVT flooring over underfloor heating, as a thicker underlay traps heat underneath and reduces heating efficiency by up to 15%.

How Does LVT Thickness Compare to Other Flooring Types?

LVT flooring ranges from 3mm to 8mm in thickness, making it thinner than engineered wood and real wood but comparable to laminate, vinyl sheet, and SPC flooring. The 9 most common flooring type comparisons with Luxury Vinyl Tile (LVT) flooring thickness are:

• LVT Flooring vs Laminate Flooring: Laminate flooring ranges from 6mm to 12mm in thickness, making it thicker than most Luxury Vinyl Flooring grades. Laminate soaks up water and swells when wet, whilst LVT flooring stays fully waterproof at every thickness grade.
• LVT Flooring vs Engineered Wood Flooring: Engineered wood flooring ranges from 10mm to 20mm in thickness, making it much thicker than all standard Luxury Vinyl Tile (LVT) flooring grades. LVT flooring at 6mm and 8mm looks just like engineered wood but handles moisture better and adds far less height to the floor.
• LVT Flooring vs Vinyl Sheet Flooring: Vinyl sheet flooring ranges from 1.5mm to 4mm in thickness, making it thinner than most standard Luxury Vinyl Flooring grades. LVT flooring at 4mm and above feels more comfortable underfoot, hides bumps in the floor better, and allows damaged sections to be replaced individually without lifting the entire floor.
• LVT Flooring vs Real Wood Flooring: Real wood flooring ranges from 18mm to 25mm in thickness, making it the thickest of all comparable flooring types. Luxury Vinyl Tile (LVT) flooring at 6mm and 8mm looks just like real wood but stays fully waterproof and adds less than one third of the floor height that real wood adds.
• LVT Flooring vs Plank Flooring: Plank flooring ranges from 10mm to 25mm in thickness, making it much thicker than Luxury Vinyl Flooring in wide plank format. LVT plank flooring at 4mm to 8mm delivers the same wide plank look at a lower thickness, lighter weight, and better moisture resistance than timber plank flooring.
• LVT Flooring vs Tile Flooring: Ceramic and porcelain tile flooring ranges from 6mm to 12mm in thickness and needs an extra 3mm to 6mm of adhesive underneath, making the total floor build-up much greater than LVT flooring. Luxury Vinyl Tiles deliver the same stone and tile look with a warmer, softer, and more slip-resistant surface than ceramic and porcelain tile flooring.
• LVT Flooring vs SPC Flooring: SPC flooring ranges from 4mm to 8mm in thickness, making it the closest comparison to standard Luxury Vinyl Tile (LVT) flooring grades. SPC flooring resists dents better than LVT flooring at the same thickness, whilst Luxury Vinyl Flooring feels softer and more comfortable underfoot than SPC at the same thickness grade.
• LVT Flooring vs Herringbone Flooring: Herringbone LVT flooring ranges from 4mm to 6mm in thickness, delivering the same eye-catching zigzag pattern as real wood and engineered wood herringbone flooring but at a much lower thickness and with full waterproof performance across all UK room types.
• LVT Flooring vs Parquet Flooring: Traditional real wood parquet flooring ranges from 18mm to 22mm in thickness, whilst Luxury Vinyl Tile (LVT) flooring in parquet formats ranges from 4mm to 6mm. LVT parquet flooring delivers the same decorative geometric look at less than one third of the total thickness, without the water damage risk and complex installation of real wood parquet flooring.

What Subfloor Requirements Does LVT Thickness Depend On?

LVT flooring thickness determines how flat, smooth, and dry the floor underneath needs to be before fitting. 

• Subfloor Flatness: 2mm and 3mm Luxury Vinyl Flooring needs the floor underneath to be no more than 3mm uneven per 1.8 metres, as thin LVT planks show every bump and dip beneath them. 5mm and 6mm Luxury Vinyl Tiles handle more unevenness underneath, saving time and money on floor levelling before fitting.
• Subfloor Smoothness: 2mm and 3mm LVT flooring needs a perfectly smooth floor underneath with no ridges, nail heads, or old adhesive lumps. 5mm and above Luxury Vinyl Flooring tolerates minor surface roughness that thinner grades transfer directly to the finished floor surface.
• Subfloor Moisture: All Luxury Vinyl Tile (LVT) flooring grades need the floor underneath to have a moisture level below 75% relative humidity before fitting. A damp floor underneath causes adhesive failure in glue-down LVT flooring and click joint separation in floating Luxury Vinyl Flooring regardless of thickness grade.
• Subfloor Strength: 6mm and 8mm LVT flooring adds more weight to the floor underneath than thinner grades, needing a solid subfloor that does not flex or bounce underfoot. A bouncy subfloor breaks apart the click joints in Luxury Vinyl Tile (LVT) flooring of all thickness grades over time.

How Does LVT Flooring Thickness Affect Cost?

Thicker LVT flooring costs more per square metre than thinner grades, as greater thickness requires more raw material. In the UK, Luxury Vinyl Tile (LVT) flooring price ranges from £8 per m² for 2mm grades to £45 per m² for 8mm grades.

• Material Cost: 2mm LVT flooring costs £8 to £15 per m², 4mm Luxury Vinyl Tiles cost £15 to £25 per m², and 6mm to 8mm Luxury Vinyl Flooring costs £25 to £45 per m² across the UK market.
• Subfloor Preparation Cost: 2mm and 3mm LVT flooring demands more subfloor levelling and smoothing before fitting, adding £5 to £15 per m² in preparation costs compared to thicker grades.
• Installation Cost: Thicker Luxury Vinyl Tile (LVT) flooring takes longer to fit due to greater plank weight and more precise click joint alignment, adding £2 to £5 per m² in labour costs compared to thinner grades.
• Long-Term Value: 6mm Luxury Vinyl Flooring with a 20 mil wear layer delivers greater long-term value than 2mm LVT flooring requiring replacement every 3 to 5 years in high-traffic rooms.

How Does LVT Flooring Thickness Affect Cost?

LVT flooring thickness directly affects cost because thicker Luxury Vinyl Tiles need more raw material, more complex manufacturing, and more floor preparation underneath before fitting. 

The price differences across standard LVT flooring thickness grades in the United Kingdom are:

• 2mm: Starts from £8 per m², best for low-traffic spaces with a perfectly flat floor underneath.
• 3mm: Averages £12 per m², best for renovation projects where the floor cannot be raised too high.
• 4mm: Averages £18 per m², best for everyday home rooms like bedrooms, living rooms, and hallways.
• 5mm: Averages £25 per m², best for busier home areas like kitchens and open-plan living spaces.
• 6mm: Averages £32 per m², best for high-traffic home rooms and light commercial spaces.
• 8mm: Averages £45 per m², best for busy commercial spaces needing the most durable and comfortable floor.

Luxury Vinyl Tile (LVT) flooring thickness adds 3 extra costs beyond the material price

• Subfloor Preparation: 2mm and 3mm LVT flooring needs more levelling and smoothing underneath before fitting, adding £5 to £15 per m² in preparation costs compared to thicker grades.
• Installation Labour: 6mm and 8mm Luxury Vinyl Flooring takes longer to fit because the planks are heavier and the click joints need more careful alignment, adding £2 to £5 per m² in labour costs.
• Door Trimming: Thicker LVT flooring raises the floor height more than thinner grades, meaning doors need trimming at an average cost of £50 to £100 per door in UK home installations.

What LVT Flooring Thickness Do You Need for Specific Applications?

LVT flooring thickness changes based on heat exposure, moisture levels, foot traffic, and the condition of the floor underneath. The 6 Luxury Vinyl Tile (LVT) flooring thickness recommendations by specific application are:

• Underfloor Heating: 4mm and 5mm LVT flooring suits underfloor heating installations. The total thickness of the Luxury Vinyl Tile and underlay together must not exceed 18mm, as thicker LVT flooring reduces underfloor heating efficiency by up to 15%.
• Wet Rooms: 5mm and 6mm Luxury Vinyl Flooring suits wet rooms needing a fully waterproof, slip-resistant floor. 5mm and 6mm Luxury Vinyl Tiles handle constant moisture and minor floor unevenness found in UK wet rooms better than 2mm and 3mm grades.
• Commercial Use: 6mm and 8mm Luxury Vinyl Tile (LVT) flooring suits busy commercial spaces like shops, hotels, and offices. 8mm Luxury Vinyl Flooring with a 20 mil wear layer delivers the best durability and subfloor tolerance of all standard UK thickness grades.
• New Build: 4mm and 5mm LVT flooring suits new build properties across the UK where the subfloor is freshly laid and level. New build subfloors need far less preparation than older floors, making 4mm and 5mm Luxury Vinyl Tiles the most cost-effective choice for new build projects.
• Heavy Furniture: 5mm and 6mm Luxury Vinyl Flooring suits rooms with heavy furniture like sofas, wardrobes, and kitchen units. 2mm and 3mm Luxury Vinyl Tile (LVT) flooring shows visible dent marks beneath heavy furniture legs within 6 to 12 months of fitting.
• Renovation Projects: 5mm and 6mm LVT flooring suits renovation projects in older UK properties where the floor underneath is uneven from old flooring removal. 6mm Luxury Vinyl Tiles handle more unevenness underneath than thinner grades, cutting preparation time and cost before fitting.

Does Luxury Vinyl Flooring Shape or Size Affect What Thickness You Should Choose?

Luxury Vinyl Flooring shape and size directly affect the thickness needed, as larger and longer planks need more thickness to stay rigid and avoid flexing underfoot. The 6 most common LVT flooring shapes and sizes and how they affect thickness choice are:

• Large Format Planks: LVT planks longer than 1200mm need at least 5mm thickness to stay rigid without bending or bowing underfoot. 4mm and below Luxury Vinyl Flooring in large plank sizes bends between click joints under daily foot traffic, causing gaps and joint separation over time.
• Small Format Tiles: Luxury Vinyl Tiles in small square sizes below 305mm x 305mm suit 2mm and 3mm thickness grades, as small tiles do not need as much rigidity as long planks to stay flat and stable. Small format LVT flooring in 2mm and 3mm grades suits glue-down fitting in low-traffic spaces with a perfectly flat floor underneath.
• Wide Plank Format: Luxury Vinyl Flooring planks wider than 200mm need at least 5mm thickness to stop the edges lifting and the plank bending sideways underfoot. 6mm wide plank LVT flooring suits rooms where the floor underneath is slightly uneven, as narrower planks show floor unevenness more visibly.
• Herringbone Planks: Luxury Vinyl Tile (LVT) flooring in herringbone format needs at least 4mm thickness to keep the angled joints between planks from pulling apart. 5mm and 6mm herringbone Luxury Vinyl Flooring suits busy rooms where the angled joints take more stress from foot traffic than straight lay formats.
• Parquet Format: Luxury Vinyl Flooring in parquet block format needs at least 4mm thickness to keep the small geometric blocks rigid and stable underfoot. 5mm LVT parquet flooring suits busy home rooms where foot traffic hits the floor from multiple directions at once.
• Large Square Tile Format: Luxury Vinyl Tiles in large square sizes above 600mm x 600mm need at least 5mm thickness to stop the corners lifting and the tile surface flexing underfoot. 6mm large square LVT flooring suits commercial spaces where a seamless, grout-free floor appearance is required.

Does Thicker LVT Always Mean Better Quality?

Thicker LVT flooring does not always mean better quality, as the right Luxury Vinyl Tile thickness depends on room type, foot traffic level, and subfloor condition. 4mm and 5mm deliver the best quality for standard UK residential installations, whilst 6mm and 8mm suit high-traffic and commercial spaces. Luxury Vinyl Flooring above 6mm in low-traffic residential rooms adds unnecessary cost, reduces underfloor heating efficiency by up to 15%, and raises floor height without delivering any measurable improvement in surface durability or wear layer performance.

How Is LVT Flooring Thickness Measured?

LVT flooring thickness is measured in millimetres (mm) from the bottom of the backing layer to the top of the wear layer using a digital calliper. Total Luxury Vinyl Tile (LVT) flooring thickness includes all 4 layers: the backing layer, the core layer, the print layer, and the wear layer. The wear layer is measured separately in mils, where 1 mil equals 0.0254mm.

The 4 layers that make up total LVT flooring thickness are:

• Backing Layer: The bottom layer that sits on the subfloor, providing moisture resistance and stability.
• Core Layer: The rigid middle layer that gives the Luxury Vinyl Flooring plank its strength and ability to handle an uneven floor underneath.
• Print Layer: The thin layer that carries the printed wood or stone look and the embossed surface texture.
• Wear Layer: The top protective layer of Luxury Vinyl Tile (LVT) flooring, measured in mils, that protects the floor from daily scratches, scuffs, and foot traffic wear.

What LVT Flooring Thickness Should Be Avoided?

2mm LVT flooring is the thickness most commonly avoided in UK homes, as 2mm Luxury Vinyl Tiles are too thin to handle everyday home use, hide uneven floors, or cope with moisture in wet areas.

• 2mm in High-Traffic Rooms: Wears out quickly in busy rooms like hallways and kitchens, needing a full floor replacement within 3 to 5 years under heavy daily foot traffic.
• 2mm and 3mm on Uneven Subfloors: Shows every bump and dip in the floor underneath on the finished surface, causing visible unevenness and faster surface wear over time.
• 2mm and 3mm in Wet Rooms and Bathrooms: Too thin to handle the constant moisture and temperature changes found in UK wet rooms and bathrooms, leading to dimensional instability and surface degradation over time.
• 6mm and 8mm Over Underfloor Heating: Acts like a blanket over underfloor heating systems, reducing heating efficiency by up to 15% and pushing energy bills up over time.
• Mismatched Thickness Grades Across Adjoining Rooms: Creates uneven height differences between room floors, needing extra threshold strips and door trimming that add unnecessary cost and break the visual flow across the floor.

8mm Luxury Vinyl Tile (LVT) flooring is avoided in quiet, low-traffic home rooms, as 8mm adds unnecessary floor height, reduces underfloor heating efficiency, and costs significantly more than 5mm and 6mm grades without delivering any better performance in everyday residential use.

How Do You Choose the Right LVT Flooring Thickness?

The right Luxury Vinyl Tile (LVT) flooring thickness is chosen based on 5 key factors: room foot traffic, subfloor condition, installation method, underfloor heating, and budget.

• Room Foot Traffic: Bedrooms and quiet rooms suit 3mm to 4mm LVT flooring. Kitchens and living rooms suit 5mm Luxury Vinyl Flooring. High-traffic rooms and commercial spaces suit 6mm to 8mm Luxury Vinyl Tiles.
• Subfloor Condition: Flat new build subfloors suit 3mm to 4mm LVT flooring. Older, uneven renovation subfloors suit 5mm to 6mm Luxury Vinyl Flooring to hide bumps and dips without extra levelling cost.
• Installation Method: Glue-down fitting suits 2mm to 4mm Luxury Vinyl Tile (LVT) flooring on a flat subfloor. Click floating and loose lay fitting suits 5mm to 8mm LVT flooring to maintain rigidity and prevent joint separation.
• Underfloor Heating: Rooms with underfloor heating suit 4mm and 5mm Luxury Vinyl Flooring. The total combined thickness of LVT and underlay must not exceed 18mm, as LVT flooring above 6mm reduces heating efficiency by up to 15%.
• Budget: 3mm to 4mm LVT flooring starts from £12 per m². 5mm to 6mm Luxury Vinyl Tile (LVT) flooring averages £25 to £32 per m². 8mm Luxury Vinyl Flooring averages £45 per m² for heavy commercial installations.

Conclusion

LVT flooring thickness directly affects durability, installation method, subfloor requirements, underfloor heating compatibility, and cost across every Luxury Vinyl Tile installation.

4mm and 5mm suit most UK homes. 6mm suits high-traffic rooms and light commercial spaces. 8mm suits heavy-use commercial installations. 2mm and 3mm are best avoided in busy rooms due to rapid wear and low subfloor tolerance.

The right LVT flooring thickness depends on room foot traffic, subfloor condition, installation method, underfloor heating, and budget.
