The floor sets the tone for an entire room before a single piece of furniture goes in, which is why choosing the right indoor floor tiles is one of the highest-impact decisions in any renovation. At Tiles Deluxe, our floor tiles collection spans large-format marble-effect porcelain, warm parquet wood-effect designs and practical anti-slip options for hallways, kitchens and bathrooms all at some of the lowest online prices in the UK. This guide walks through everything you need to specify indoor flooring with confidence, from slip ratings to grout colour, and showcases the collections our customers are choosing most in 2026.
Porcelain has become the default choice for ambitious UK interiors because it delivers the visual drama of natural marble, limestone or timber without the ongoing maintenance headache. It resists scratches from pet claws, doesn’t stain from red wine or turmeric, and unlike engineered wood never needs refinishing. Large-format slabs at 60x120cm minimise grout lines across an open-plan kitchen-diner, creating the seamless, uninterrupted look currently dominating new-build and renovation projects across London, Leicester and beyond.
Matt vs Polished: Which Finish Suits Your Room?
Every marble-effect range in our collection is available in both matt and polished finishes, and the choice genuinely changes the character of a room. A polished finish reflects light beautifully, making it a favourite for darker hallways, north-facing kitchens or smaller flats where you want to maximise brightness though it will show footprints more readily and needs a slightly softer cleaning routine to avoid dulling the sheen. A matt finish hides everyday marks far better, offers a subtly grippier surface underfoot, and tends to feel warmer and more contemporary, which is why it’s become the default choice for large open-plan living spaces.
- Polished hallways, dark rooms, smaller spaces needing extra light bounce
- Matt living rooms, family kitchens, busy households with children or pets
- Anti-slip R10 bathrooms, utility rooms, conservatories

Grey remains the most popular colour family across the whole of our floor tiles range, and for good reason it’s endlessly versatile, works with warm or cool wall colours, and hides everyday scuffs exceptionally well.

For anyone drawn to timber flooring but wary of scratches, water damage or ongoing sanding and sealing, wood-effect porcelain is the practical middle ground. Our Alberta Chateau Grey parquet-style tile replicates traditional French chevron flooring in a hardwearing, pet-and-child-proof surface that also works beautifully with underfloor heating, unlike solid wood.

Practical Considerations: Underfloor Heating, Grout & Installation
Porcelain is one of the most efficient floor coverings for underfloor heating, conducting warmth evenly across the room far better than carpet or engineered wood. Most of our indoor ranges are rectified meaning the edges are precision-cut after firing which allows for a slim 2–3mm grout joint for that coveted seamless, large-format look. We recommend a flexible tile adhesive and a matching grout shade from our adhesive and grout range, including the popular Gel-Tec S1 Flexible Tile Adhesive, which is suitable for large-format porcelain over underfloor heating systems.
Choosing a Slip Rating for Wet Rooms
If your indoor floor extends into a wet room, utility room or connects directly to a garden via bifold doors, look for our R10-rated finishes such as Bellagio Beige and Bellagio Grey Anti-Slip, which offer extra grip without sacrificing the polished aesthetic of the wider room. For fully exposed patios, always step up to our R11-rated outdoor tiles collection.

Frequently Asked Questions
What’s the difference between matt and polished porcelain?
Polished porcelain has a reflective, glossy surface that bounces light around a room, while matt porcelain has a soft, non-reflective finish that hides everyday marks and offers slightly better grip underfoot.
Can indoor porcelain tiles be used with underfloor heating?
Yes porcelain is one of the best-performing floor coverings for underfloor heating, conducting and retaining heat efficiently. Always use a flexible adhesive rated for underfloor heating systems.
What size grout joint should I use with large-format tiles?
Because our large-format ranges are rectified, a joint of 2–3mm is typical, giving a clean, seamless finish. Your installer can confirm the exact spacing recommended for your specific tile and subfloor.
Do you offer free samples before ordering?
Yes, every tile in our indoor collection is available as a full-size, next-day delivery sample, with the sample cost refunded automatically when you place a full order.
Is porcelain flooring suitable for kitchens with pets?
Absolutely porcelain resists scratches from claws, doesn’t stain from spills, and is far more hardwearing than laminate or engineered wood, making it a popular choice among our customers with dogs and cats.
