Porcelain tile quality

How to determine the quality of a porcelain tile.

How can I judge the quality of a porcelain tile?


There are several factors to consider when judging the quality of a porcelain tile:


Density: Porcelain tiles are made from a denser clay than other types of tile, which makes them more durable and resistant to moisture.


Water Absorption: Porcelain tiles have a water absorption rate of less than 0.5%, which makes them suitable for indoor and outdoor use.


PEI rating: PEI rating is a measure of a tile's resistance to wear and tear. Tiles with a higher PEI rating are more suitable for high traffic areas.


Surface finish: Porcelain tiles come in a variety of finishes, including polished, honed, and textured. The finish of a tile can affect its slip resistance and durability.


Quality Control: Quality control is important for ensuring that tiles are consistent in size and color, and that they meet industry standards for strength and durability.


Brand reputation: Look for a reputable brand with a history of producing high-quality tiles, and check customer reviews to see what other people have experienced with the product.


Warranty: Look for a tile that comes with a warranty that protects against defects in workmanship and materials.



It can be difficult to judge the quality of a porcelain tile just by looking at it. Some factors, such as surface finish and colour, can be visually assessed, but others, such as density and water absorption rate, are not visible. However, there are some things you can look for to get an idea of the tile's quality:


Look for uniformity in size and colour: Tiles that are consistent in size and colour are generally of higher quality.


Check for defects: Look for chips, cracks, or other defects in the tile.


Check the surface finish: A smooth, glossy finish is generally indicative of a high-quality tile.


Check the edges: Check the edges of the tile to make sure they are clean and straight, with no rough or jagged edges.


Brand reputation: Look for a reputable brand with a history of producing high-quality tiles, and check customer reviews to see what other people have experienced with the product.


It's important to remember that even if a tile looks good on the surface, it may not be of high quality. It is always recommended to check the technical specifications and certifications of the tile before purchasing.



Technical specifications and certifications are important indicators of a tile's quality and performance. Some of the most important technical specifications and certifications to look for when purchasing tiles include:


Water Absorption: The water absorption rate of a tile is a measure of how much water it can absorb before it begins to deteriorate. Tiles with a water absorption rate of less than 0.5% are considered porcelain tiles and are suitable for indoor and outdoor use.


PEI rating: The PEI rating is a measure of a tile's resistance to wear and tear. Tiles with a higher PEI rating are more suitable for high traffic areas.


Breaking strength: Breaking strength is a measure of a tile's strength and durability. Tiles with a higher breaking strength are more resistant to damage.


Slip resistance: Slip resistance is a measure of a tile's ability to prevent slips and falls. Tiles with a high slip resistance rating are more suitable for wet or high traffic areas.


Certifications: Tiles that have been certified by organizations such as the Porcelain Enamel Institute (PEI) and the Ceramic Tile Institute of America (CTIOA) have been tested and found to meet industry standards for quality and performance.


ASTM Standards: Tiles that meet ASTM Standards are considered to be of good quality and are suitable for use in residential and commercial settings.


ISO Standards: Tiles that meet ISO Standards are considered to be of good quality and are suitable for use in residential and commercial settings.


It is important to note that not all tile manufacturers or brands have the same certification and it can vary according to the region. It is always recommended to check the certifications and standards of the tile before purchasing.

By Maria Parker, on behalf of The Building Guidance Partnership After years spent supporting homeowners through renovations, refurbishments, and major house builds, I have come to recognise one of the most underestimated threats to a smooth project: decision fatigue . It is not something most people anticipate. They assume the hardest parts will be structural – digging foundations, handling planning permission, or getting the budget right. But time and again, I have seen confident, capable clients brought to a standstill by the weight of ongoing decisions. And when decision-making slows down, costs rise , timelines stretch, and tension builds – particularly between homeowners and their builders. Let me explain, and offer a few ways to avoid falling into the same trap. What is Decision Fatigue? In simple terms, decision fatigue is mental exhaustion caused by the sheer number of choices you must make. During a house build or renovation, these decisions start early and come thick and fast: • Where should the sockets go in the kitchen? • What colour grout do you want in the bathroom? • Should that internal wall be moved by 200mm? • Brass, black, chrome or stainless steel fittings? • Is that the final position for the staircase? Each choice might seem small. But taken together – over weeks or months – they can become overwhelming. At some point, the brain starts resisting further decisions. People become indecisive, irritable, or worse, disengaged. And that is where delays creep in. Case Study 1: A Delayed Kitchen Because of a Tap One client, mid-way through a large refurbishment in West London, stalled an entire kitchen installation for nearly three weeks over a decision about a boiling water tap. It was not just the tap. It was also the worktop cut-out size, the under-sink space, the filtered water compatibility, the colour matching, the brand reliability, and the energy usage. Each question led to another. Eventually, the builder had to move to another part of the house while they waited – which not only slowed things down but resulted in added costs due to subcontractor scheduling changes. This delay could have been avoided. How Builders and Project Coordinators Can Help As professionals, we need to recognise that clients are not builders. They are not used to making dozens of technical decisions a week. Support is essential. Here is how we approach it at The Building Guidance Partnership: 1. Structure the Decision-Making Process We break decisions into phases. For example: • Stage 1: Planning-Level Choices – room layout, extension sizes, stair positions. • Stage 2: Services & Infrastructure – lighting zones, socket locations, plumbing routes. • Stage 3: Finishes & Fixtures – tiles, taps, cabinetry, flooring. • Stage 4: Final Details – door handles, light switch styles, paint finishes. By spreading the load and giving clients clear deadlines, we help them feel more in control. 2. Provide Shortlists Rather Than Endless Options Builders and designers can present two or three suitable choices – not fifty. This is particularly valuable when a decision has cost or structural implications. We had a client in Harrow who was agonising over bi-fold doors for the rear extension. Instead of overwhelming him with catalogues, we presented a shortlist of three suppliers (each with known reliability and pricing), with a simple pros-and-cons table. Decision made that same week. 3. Create Mock-Ups or Use Visualisation Tools Many people struggle to picture what a change will look like. Builders can offer mock-ups, 3D renders, or even mark positions on-site with tape or chalk. I recall a project in Finchley where a couple could not agree on where the island unit should go. The builder measured and taped it out on the floor, then brought a few chairs in so they could test how it felt to move around. The decision was settled that same afternoon. Case Study 2: Stair Design Delaying the Whole Build A young family undertaking a loft conversion near Watford became paralysed by indecision over the design of their new staircase. Should it turn left or right at the landing? Should it have open treads or be fully closed? What about under-stair storage? These decisions affected the wall placements, the lighting layout, and the delivery time of key materials. Because no one pushed for resolution, the entire first fix was delayed. This is where an experienced builder or coordinator adds real value. By explaining dependencies and helping to visualise impact, they can gently push the process forward. Builders: Communicate the Consequences of Delay One of the biggest complaints I hear from builders is: “The client is taking too long to decide.” But from the client’s point of view, they often do not realise how serious a delay can be. That is why I encourage all builders to clearly explain the knock-on effects: • “If you do not confirm the lighting this week, the electrician will not return until next month.” • “We need the tile choice by Tuesday to finish the waterproofing on time.” • “Your delay in choosing the bath has now pushed back the floor tiling, which affects the joiner’s schedule.” Transparency builds trust. And it encourages clients to focus their attention where it is most needed. How Homeowners Can Protect Themselves If you are about to begin a building or renovation project, here is how you can reduce the risk of decision fatigue: • Prepare early: Visit showrooms, look through Pinterest or Houzz, and narrow down your preferences in advance. • Make a scrapbook or vision board: This helps professionals quickly understand your style and avoids repeating the same discussion. • Rely on professionals: Engage a project manager, designer, or an experienced builder who can guide you and reduce the burden. • Set time aside for decisions: Make sure you are not trying to squeeze key discussions in between meetings or while juggling childcare. Closing Thoughts Every successful building project relies not only on bricks, steel, and timber – but on thousands of decisions made at the right time. Decision fatigue can quietly erode the best-laid plans unless recognised and tackled early. At The Building Guidance Partnership, our role is not just to manage logistics. It is to protect clients from overwhelm , keep the project flowing, and help everyone – builders included – stay on track. If you are about to start a renovation or extension, speak to us. A little guidance at the right time can prevent weeks of delay and thousands in extra cost.

A 5 Amp socket circuit offers a refined and intelligent approach to lamp lighting within the home. Often favoured by competent interior designers, this system uses round-pin sockets, allowing multiple lamps within a room to be controlled from a single wall switch. The result is a more cohesive lighting scheme that is both practical and visually appealing. Key Benefits: • Convenience and Cohesion: Instead of switching each lamp on individually, a single switch can activate all lamps connected to the circuit. This is ideal for setting the mood instantly when entering a room, or for creating a comfortable, settled atmosphere in the evening. • Design-Led Lighting: Interior designers often specify 5 Amp circuits during the early planning stages, recognising their ability to streamline lamp lighting and eliminate unsightly trailing wires. This contributes to a neater, more curated space. • Discreet Floor-Level Sockets: These circuits are generally designed with sockets positioned at floor level, rather than on walls. This enables lamps to be placed away from wall corners - perhaps in the middle of a room near a sofa or armchair - without causing a trip hazard or cable clutter. • Safer and More Flexible Layouts: This arrangement offers greater freedom in furniture placement, supporting a layout that prioritises both aesthetics and function. It is particularly useful in living rooms, bedrooms, and snug areas where ambient lighting is a key feature. • Part of a Professional Lighting Plan: A 5 Amp circuit should ideally be considered during the early design phase of a build, extension, or refurbishment project. This allows it to be properly priced within the tender process and coordinated with other electrical work and furniture layouts. In summary, a 5 Amp socket circuit brings together elegance, functionality, and ease of use. Competent interior designers use this system to create lighting plans that feel seamless and intuitive. For homeowners embarking on a new build or renovation, it is worth exploring this option to achieve a warm, well-thought-out environment.
