How to Choose Bathroom Tiles A London Renovator's Guide

Choosing the right tile for your bathroom is one of the biggest decisions you'll make in a renovation. It's a delicate dance between three things: the look you've fallen in love with, the realities of your budget, and the practical demands of the room itself. Get that balance right, and you'll have a space that not only looks fantastic but also works for you, day in and day out.

Your Essential First Steps in Choosing Bathroom Tiles

It’s easy to get swept up in the excitement of a bathroom project and head straight for the beautiful, eye-catching tiles. But before you let your heart rule your head, we need to talk about the practicalities. The biggest mistake I see homeowners make is choosing a tile that just isn't right for their space, leading to problems down the line.

Think about it. A busy family bathroom floor takes a serious beating and needs a tough, water-resistant tile. That's a world away from the creative freedom you have with a splashback in a rarely-used guest loo. A tiny, cramped London bathroom has different needs entirely from a sprawling, open-plan wet room where nearly every surface is a splash zone.

Key Considerations to Start With

So, where do you begin? The first step is always to look at your room with a critical eye. A tile that’s perfect for a feature wall could be a slippery, hazardous disaster on a shower floor.

Ask yourself these fundamental questions:

• Where is it going? Is it for the floor, the walls, or inside the shower enclosure? Floor tiles have to be tough and slip-resistant. Wall tiles can be more delicate and decorative.
• How wet will it get? There's a big difference between a powder room and a full wet room. The wetter the area, the more you need a tile with very low water absorption, like porcelain.
• Who uses the space? A family bathroom needs tiles that are practically bomb-proof – easy to clean and able to withstand a lot of wear and tear.

After guiding hundreds of London bathroom renovations, I can tell you this: the projects that stand the test of time are always the ones where function was considered first. People who nail the practical side are always the happiest in the long run.

An Introduction to Tile Materials

Once you've got a handle on your room's non-negotiables, you can start exploring the fun stuff: the materials. For most bathrooms, you'll be looking at three main players: porcelain, ceramic, and natural stone. Each has its own distinct personality and purpose.

Porcelain is the workhorse of the bathroom world. It's incredibly dense, tough, and almost completely waterproof, making it the undisputed champion for floors and wet areas. Ceramic, its close cousin, is a bit softer and more porous. This makes it a fantastic and often more budget-friendly option for walls or floors in low-traffic areas.

Then you have natural stone—materials like marble, slate, and travertine. Nothing beats stone for pure, one-of-a-kind luxury. The catch? It demands more care, including regular sealing to protect its natural beauty from stains and water.

To help you get a feel for the options, let’s break down the basics of these common materials.

Bathroom Tile Material Quick Comparison

This table gives a quick overview to help steer your initial thinking.

Material Type	Best For	Durability	Maintenance	Typical Cost
Porcelain	Floors, Wet Rooms, Showers	Very High	Low	Medium-High
Ceramic	Walls, Low-Traffic Floors	Medium	Low	Low-Medium
Natural Stone	Feature Walls, Luxury Floors	Varies	High	High

Remember, this is just a starting point. The best choice always comes back to your specific room and how you live in it.

Getting the Foundations Right: Your Bathroom's Practical Needs

It’s easy to get swept away by a beautiful tile pattern, but before you fall in love with a look, we need to talk about the practical side of things. I’ve seen it countless times: a stunning tile choice that fails within a year because it simply wasn't right for the job.

The secret to a bathroom that looks great for decades is matching the tile to the specific demands of the space. Think about it. A tiny guest loo in a London flat has completely different needs than a busy family bathroom that’s been converted into a full wet room. One gets occasional use, while the other faces a daily deluge of water and foot traffic. Getting this first step right is everything.

Water, Wear, and Why They Matter

Before you even think about colour, there are two technical details that should be at the top of your list: the tile's water absorption rate and its durability rating. These aren't just numbers on a spec sheet; they are your best insurance against cracked tiles and damp issues down the line.

Water absorption is exactly what it sounds like – how much moisture a tile will soak up. For any part of your bathroom that gets wet, especially shower walls and wet room floors, you need a tile that’s practically waterproof. This is where porcelain is the undisputed champion, with a water absorption rate of less than 0.5%. This makes it 'impervious' to water and, frankly, the only sensible choice for these high-moisture zones. Proper tanking is also crucial for a watertight finish; our guide on damp proof membranes explained covers this in more detail.

Next up is durability. For glazed tiles, this is measured using the PEI rating (from the Porcelain Enamel Institute), which grades a tile’s resistance to wear and tear on a scale from 1 to 5.

• PEI 1: Wall use only. Don't even think about walking on it.
• PEI 2: Fine for walls in light-use areas, like a guest bathroom.
• PEI 3: The go-to for most residential bathroom floors. It can handle normal, everyday foot traffic.
• PEI 4 & 5: Overkill for homes. This is for commercial spaces like shops and airports.

For your main family bathroom floor, a PEI 3 rating hits the sweet spot. You get all the durability you need without paying a premium for a commercial-grade tile you don’t.

Planning for Underfloor Heating

Nothing beats the feeling of a warm floor on a cold British morning, which is why underfloor heating (UFH) is no longer a luxury but a common feature in bathroom renovations. But if you want that cosy-toes experience, you have to choose a tile that plays well with the heating system.

The magic word here is thermal conductivity. You need a tile that allows heat to pass through it easily and efficiently.

The best performers for underfloor heating are dense and relatively thin materials. Both porcelain and ceramic tiles are fantastic conductors. They warm up fast, hold the heat well, and give you that wonderful warmth without needing to crank the system up to full blast.

Natural stones like marble and slate are also brilliant with UFH, thanks to their inherent density. On the flip side, materials like vinyl or thick carpet act as insulators, trapping the heat and preventing it from warming the room. While you might be focused on looks, considering how your tile works with your heating is a practical decision you’ll be thankful for every winter. Of course, tile isn't the only source of warmth; you can find beautiful and effective modern bathroom radiators that complement any design.

Putting these practical considerations first doesn't take the fun out of choosing tiles. It just ensures your beautiful new bathroom is also functional, safe, and built to last, protecting your investment for years to come.

Choosing the Right Tile Material and Finish

You’ve mapped out the practical side of your bathroom. Now for the fun bit – picking the actual tiles. This is where your bathroom's personality really comes to life, but it's also a decision that affects how long it will last and how much work it'll be to look after.

Let's cut through the jargon and look at the main players: porcelain, ceramic, and natural stone. Each has its place, and knowing the difference is key to getting it right.

Porcelain vs. Ceramic: What’s the Real Difference?

People often use these terms interchangeably, but in my experience, knowing the distinction is crucial. Think of them as close relatives with very different strengths.

Ceramic tiles are your go-to for walls. Made from a softer clay, they’re easier for your tiler to cut and shape, which can save a bit on labour costs. The glaze on the surface makes them perfectly water-resistant for splashbacks and general wall areas. Just don't put them on a high-traffic floor.

That’s where porcelain comes in. Fired at much higher temperatures from a denser clay, it's the tough one of the family. It's incredibly durable and almost completely waterproof, with a water absorption rate of less than 0.5%. This is why it’s the only real contender for busy bathroom floors, shower enclosures, and the entirety of a wet room.

A Quick Tip from Experience: For a family bathroom floor, I always steer clients towards porcelain. It stands up to everything life throws at it – from dropped toiletries to constant puddles – in a way that other materials simply can't.

The Unmistakable Charm of Natural Stone

If you’re after a truly luxurious or unique finish, nothing quite compares to the character of natural stone. Every single tile is different, bringing a depth and variation that man-made tiles can only aspire to imitate.

• Marble: The classic choice for a high-end, elegant bathroom. But be warned, it's a softer, porous stone that will scratch and stain if you don't seal it properly and look after it.
• Travertine: Perfect for a warmer, more rustic aesthetic, thanks to its signature pitted surface. Those pits, however, need to be filled and the tile sealed regularly to stop water from getting in.
• Slate: I love using slate for its deep, rich colours and naturally textured surface, which gives it fantastic grip. It's tough, but like all stone, it still needs sealing to protect against stains and moisture.

Opting for natural stone is as much a lifestyle choice as a design one. The look is second to none, but you have to be ready for the upkeep it demands.

Why the Finish is a Safety-Critical Decision

Beyond the material, the finish on your tile is a decision you can't afford to get wrong, especially on the floor. It affects how the room looks, how easy it is to clean, and, most importantly, how safe it is.

A gloss finish is brilliant for walls. It bounces light around, making a small bathroom feel bigger and brighter, and is an absolute dream to wipe clean. Put that same tile on a floor, though, and it becomes a slippery nightmare the second it gets wet.

This is where matte and textured finishes are your best friends for flooring. A matte finish gives a more modern, subtle look and offers far more grip. Textured tiles go even further, providing a surface designed for slip resistance, making them a non-negotiable for wet room floors.

In the UK, we take slip resistance very seriously. A tile’s grip is measured using a Pendulum Test Value (PTV), and for any wet area where you'll be barefoot, you should be looking for a rating of 36 or higher. The UK Health and Safety Executive reports that slips in the bathroom are behind more than 25% of accidents at home each year. This isn't just about following rules; it's about keeping your family safe. You can discover more insights about choosing slip-resistant tiles and why it's a top priority for any bathroom project.

Using Size and Pattern to Define Your Style

This is where the real fun begins. Once you’ve nailed the practical side of materials and finishes, you get to play with the size, colour, and pattern of your tiles. These are your most powerful tools for shaping the entire mood of your bathroom—it’s about more than just picking a tile you like, it’s about using them to create character and even the illusion of space.

Having renovated countless London bathrooms, we’ve seen first-hand how the right tile can completely redefine a room. A clever choice can make a cramped ensuite feel airy and open, while a bold pattern can turn a featureless wall into a genuine centrepiece.

Large Format Tiles for an Expansive Feel

One of the best tricks in the book for making a small bathroom feel bigger is to use large format tiles. We’re talking about tiles that are 60x60cm or even larger. It might sound wrong, but the secret is all in the grout lines.

Fewer grout lines mean a less "busy" surface, which tricks the eye into seeing a single, seamless expanse. In many London properties, where bathrooms can be notoriously compact, this technique is an absolute game-changer. An uninterrupted flow just makes everything feel bigger and calmer.

Small Tiles for Character and Focus

While large tiles are great for creating a sense of space, small tiles are where you can really inject personality and create stunning focal points. Think of shimmering mosaics behind a basin, classic metro tiles in a shower, or a detailed pattern across the floor.

• Mosaic Tiles: These tiny tiles are brilliant for adding texture and a touch of luxury. We often use them to create a feature wall, line a shower niche for a pop of colour, or add a decorative border.

• Metro (or Subway) Tiles: A timeless classic for a reason. You can keep it traditional or put a modern spin on it by laying them in a herringbone or vertical stack pattern.

• Patterned Tiles: These are perfect for making a statement, especially on the floor. A bold geometric or encaustic-style tile can easily become the main design feature of the whole room.

For more inspiration on using tiles to make a big impact in a smaller space, have a look at our guide to bathroom tile ideas for a small bathroom.

Our Pro Tip: If you've fallen for a bold pattern but worry it might overwhelm a small room, use it on the floor. A pattern on the floor feels grounded and intentional rather than chaotic, as it exists on a single, uninterrupted plane.

Working with Period Properties

So many London homes come with beautiful Victorian or Edwardian bones, and your tile choice is a great opportunity to honour that heritage. This doesn’t mean your bathroom has to look like a museum piece—it’s about blending classic style with modern functionality.

For a Victorian bathroom, we often recommend geometric floor patterns in black and white or rich heritage colours. On the walls, classic square or metro tiles help maintain that authentic feel. For Edwardian properties, which tend to have a lighter, airier aesthetic, you might opt for metro tiles with a softer, contrasting grout or even delicate floral-inspired patterns. The key is to find shapes and patterns that give a nod to the building's original character.

The Decisive Role of Grout

Never, ever underestimate the power of grout. It’s a small detail that can completely transform the final look of your tiling. The choice is really quite simple: do you want it to blend in or stand out?

A matching grout colour creates a subtle, uniform look. It helps the tiles merge, which is perfect if you’re using large format tiles to make a room feel bigger or if you want the tile pattern itself to be the main focus.

On the other hand, a contrasting grout makes each individual tile pop. Think of the classic, graphic look of white metro tiles with a dark grey or black grout—it instantly adds definition and visual interest without needing to introduce a whole new colour or material into your design scheme.

Budgeting, Sourcing, and Working With Your Installer

Getting the tiles you love is one thing; getting them on the wall beautifully is another. This is where the practical side of things kicks in – the money, the logistics, and the people you hire. Let’s get real about what it actually costs, how to find your tiles, and, most importantly, how to communicate with your fitter to get the flawless finish you're paying for.

Think of this as your project management briefing. We'll cover everything from breaking down a quote and ordering the right amount of tiles (with the crucial extra for cuts!) to giving your tiler a spec sheet that leaves no room for error.

Understanding the Full Cost of Tiling

When you're budgeting, looking at the price per square metre for a tile is just the tip of the iceberg. I've seen too many budgets blow up because of the 'hidden' costs. To get a realistic figure, you need to account for everything that goes into the job.

A good, professional quote should always break these things down for you. Your total investment will really include:

• The Tiles: This is the obvious one, your primary material.
• Labour: The tiler’s day rate or a fixed price for the entire job.
• Adhesives & Grout: Don’t skimp here; these are specialist materials that ensure longevity.
• Waterproofing: This is non-negotiable. It involves tanking membranes and sealants, especially in showers and wet areas.
• Trims: Those metal or plastic strips that give edges a sharp, professional finish.
• Preparation: Your walls or floor might need work first, like screed to level a floor or backer boards for walls.

Remember, tile prices can swing wildly. You can find perfectly good ceramics for under £20 per square metre, but designer porcelain or natural stone can easily top £100. A word of advice: don't let a pricey tile eat your entire budget. Good installation is just as important as the tile itself.

If the budget is tight, you might not even need to rip everything out. Before you commit, look into some clever bathroom tile cover up ideas that can deliver a fresh look for less.

Sourcing Your Tiles and Planning for Wastage

Finding the perfect tile is a hands-on job. Whatever you do, never order tiles based on a picture you saw online. I can't stress this enough. The way a colour appears on a screen can be miles away from how it looks in your home.

Always order physical samples. Get a few, place them in your bathroom, and live with them for a couple of days. See how they look in the morning light, under your artificial lights at night, and next to your vanity and taps. It’s the only way to be 100% sure.

Once you’ve found ‘the one’, it's time to do the maths. Measure the area you need to tile, then add a contingency for wastage. We always tell our clients to order an extra 10-15%.

This isn't about upselling; it's a practical necessity. That extra amount covers tiles that might get broken in transit, mis-cuts during installation (especially with complex patterns), and all the fiddly cuts around pipes and windows. It also leaves you with a few spares for any future repairs, which is a lifesaver because tile batches vary slightly in colour and finish over time.

Working With Your Installer for a Flawless Finish

The final look of your project really comes down to the communication between you and your installer. A great tiler is a craftsperson, but they aren't a mind reader. Giving them a detailed brief isn't being 'difficult' – it’s being a good client and ensuring you get what you want.

Your instructions should be written down, clear, and agreed upon before a single tile is laid. This simple document prevents costly and frustrating misunderstandings.

Key Details to Specify to Your Tiler:

• Layout Pattern: Don’t just say "brick bond." A quick sketch showing if you want a 50/50 split, a one-third running bond, herringbone, or a stacked layout is invaluable.
• Grout Lines: Specify the width. Do you want thin 2mm lines for a modern look or a more standard 3mm? It makes a huge difference.
• Grout Colour: Be precise. Don't say "grey"—specify the brand and exact name, like "Mapei 111 Silver Grey."
• Trim Details: What colour, material, and profile do you want for the edges? Chrome, matte black, square edge, rounded edge? Put it in writing.
• Start Point: This is a pro tip. Discuss where the tiler will start from. You want to make sure any cut tiles end up in the least noticeable spot, like behind a door or under a vanity, not right in the doorway.

This little bit of prep work makes all the difference between a good job and a great one. And if you're undertaking a bigger renovation, knowing how to find the right trades is crucial. Getting some background on choosing the right bathroom fitter in London can set your project up for success from the very beginning.

Common Tiling Mistakes and How to Avoid Them

After fitting hundreds of bathrooms across London, you start to see the same tripwires. It’s easy to get swept up in the excitement of choosing tiles, but a few simple oversights can lead to costly headaches and a finish you’re less than thrilled with.

Think of this as your final check before committing – a little bit of insider knowledge to make sure your project goes off without a hitch.

Under-Ordering and Batch Variations

We've seen it happen more times than I can count. You're a few tiles short of finishing, you order another box, and… the shade is just slightly off. It’s a subtle difference, but once you see it, you can’t un-see it. This comes down to batch variations during manufacturing.

The rule is simple: calculate your total square meterage, then add an extra 10-15% on top for cuts, wastage, and potential breakages. This isn't just a 'nice-to-have'; it's your insurance policy for a uniform finish. It also leaves you with a few spares for any future repairs, which is a lifesaver.

When the delivery van leaves, don't just stack the boxes in the corner. Open them up and do a quick two-minute check:

• Look for the batch number on each box. Do they all match? If not, you have a problem.
• Quickly inspect the top layer of tiles for damage. Couriers aren’t always gentle.

Report any issues to your supplier immediately, before a single tile has been laid. This tiny step can save you a world of frustration.

Material and Maintenance Missteps

Another classic mistake is choosing a tile purely on aesthetics, without thinking about the practicalities. That gorgeous, porous natural stone you’ve fallen for? If it’s unsealed travertine on a shower floor, it's going to soak up water, soap, and grime, leading to stains and damage.

Always check that the tile’s technical specs are a match for its intended use. Looks are only half the story.

A very bold, on-trend tile can look fantastic now, but might make your bathroom feel dated in five years. If you’re set on a statement pattern, why not use it as a feature on a smaller splashback or a contained floor area? It adds personality without becoming a huge commitment you might regret later.

Be brutally honest with yourself about maintenance, too. A stunning polished marble looks incredible, but it demands regular sealing and careful cleaning. If you have a busy family and just want something you can quickly wipe down, a high-maintenance tile will become a burden, not a joy.

The Final Pre-Purchase Checklist

Right, before you click 'buy' or tap your card, just run through this one last time. This is the final barrier between you and a potential mistake.

1. Have you held a real sample in your hand? And have you looked at it in your own bathroom, under your own lights, at different times of day?
2. Is the material genuinely right for the space? Check its water absorption rating for wet areas and its durability (PEI rating) for floors.
3. Is the floor tile safe? For a wet room or shower area, you're looking for a PTV slip rating of 36+. No compromises.
4. Have you ordered that 10-15% extra? Seriously, don't skip this.
5. Does this choice fit your real life? Are you honestly prepared for the cleaning and upkeep it requires?

Taking a moment to tick these boxes isn't about slowing down the process. It's about making sure you get it right the first time, so you can enjoy the result for years to come.

Your Bathroom Tile Questions, Answered

When it comes to choosing bathroom tiles, it’s natural to have questions. After years of renovating homes across London, from Fulham to Kensington, we’ve heard just about all of them. Here are our straightforward answers to the queries that pop up time and time again.

What Is the Best Tile for Underfloor Heating?

If you’re installing underfloor heating, you need a tile that’s a good thermal conductor. In simple terms, it needs to get the heat from the pipes or wires under the floor to your feet efficiently, without wasting energy.

Both porcelain and ceramic tiles are fantastic for this. They’re dense materials that heat up quickly and hold that warmth really well, giving you that lovely cosy feeling underfoot. Natural stones like marble, slate, and travertine are also excellent heat conductors and work brilliantly with these systems.

Can You Tile Over Existing Tiles?

Technically, yes, this is possible. But in our professional experience, it’s a shortcut we almost always advise against.

Tiling over an existing layer adds significant weight to the floor or wall and creates a noticeable step-up at doorways, which can be a real pain. The biggest risk, though, is what might be lurking underneath. You have to be 100% certain that the original tiles are perfectly level, solid, and free from any damp issues. If not, you’re just wallpapering over cracks, and it will lead to a catastrophic failure down the line.

We always advise our clients to strip everything back to the substrate. It's the only way to guarantee a high-quality, long-lasting finish and ensure you're not building on top of a hidden problem. It’s a non-negotiable part of how we work.

How Can I Make My Small Bathroom Feel Bigger?

This is a classic London design challenge! The best trick in the book is to use large-format tiles and pair them with a matching grout colour.

Having fewer grout lines creates a less cluttered, more unified surface. This simple visual trick makes the brain perceive the space as larger and more serene. Light colours—think soft whites, pale greys, or warm neutrals—are your best friend here, as they reflect light and make the room feel brighter and more expansive. For an extra boost, consider a gloss finish on the walls to bounce even more light around.

What Is the Most Timeless Tile Choice?

If you want a look that will stand the test of time, stick with classic shapes and neutral palettes. You simply can't go wrong with a white or off-white tile in a traditional format.

A 3x6 inch metro tile or a simple 12x12 inch square tile has remained popular for over a century for good reason. They create a clean, versatile canvas that complements any style of fittings or décor you might choose to add years from now.
