Bathroom Tiles and Sanitaryware: A UK Buyer's Guide

Last updated: 20 June 2026 · By Mossy Tariq, Founder — Property Blueprint Co.

Tiles and sanitaryware are the two halves of a bathroom you actually see. The tiles are the walls and floor; the sanitaryware is the suite — the WC, the basin, the bath, the shower. Everything else in the room exists to serve them. So when a bathroom looks expensive, it is usually because these two were chosen well, and when it looks cheap despite a real budget, it is usually because one of them was chosen badly.

They are also the two decisions that are hardest to undo. A tap can be swapped in an afternoon; a fully tiled wall and a back-to-wall WC cannot. These are fifteen-year choices made in an afternoon at a showroom, which is exactly the wrong amount of time, and getting them right is less about taste than about a short list of practical questions most buyers never get asked.

Tiles and sanitaryware are chosen to be lived with for fifteen years and on display every day — so durability decides them, not the showroom.

What follows is the buyer's guide to choosing bathroom tiles and sanitaryware in the UK — the materials, the safety rating that matters on a floor, the suite formats, and the approvals that decide what a plumber can legally fit.

Why tiles and sanitaryware set the whole bathroom

A bathroom is read as a set of surfaces and fittings, and tiles and sanitaryware are nearly all of both. The tiles define the colour, the light, and the sense of space; the sanitaryware defines the style and the function. A considered pairing — a calm tile and a clean suite — reads as designed at almost any budget, while a mismatch between an expensive suite and a busy, ill-chosen tile reads as unresolved no matter what was spent.

They also carry the durability of the room. Tiles take water, footfall, and cleaning for the life of the bathroom; sanitaryware is used every day and is the part most exposed to limescale and wear. Both are bought once and lived with for well over a decade, which is why the selection deserves far more than the showroom afternoon it usually gets. They are the largest single share of the visible bathroom renovation cost, and the place where money spent well shows most.

How do you choose bathroom tiles

Start with the material, because it sets both the price and the performance. Three dominate UK bathrooms, and each suits a different brief.

• Porcelain. Dense, hard-wearing, and low-porosity, which means it absorbs almost no water — the reason it is the default for both walls and floors in a bathroom. It costs more than ceramic and is harder to cut, but it is the most durable and the most forgiving of a wet room.
• Ceramic. Softer and more porous than porcelain, cheaper, and easier to cut. It is well suited to walls, where it takes no footfall, but a more limited choice on a floor that will be wet. For most wall tiling it is the value option.
• Natural stone. Marble, limestone, slate, and travertine bring a material no manufactured tile matches, at the highest price and the highest maintenance — most stone is porous and has to be sealed and resealed to survive a bathroom. It rewards the budget and the upkeep, and punishes the buyer who wants neither.

Then consider format and finish. Large-format tiles mean fewer grout lines, which reads as calmer and is easier to keep clean, but they demand a flatter wall and floor to lay well. Rectified tiles, cut to a precise edge, allow the narrow grout joints that make a modern bathroom look seamless. The finish matters too: a polished wall tile reflects light and opens a small room, while the floor needs a different consideration entirely — slip resistance.

Which floor tile is safe in a wet bathroom

The single most important property of a bathroom floor tile is one most buyers never ask about: how slippery it is when wet. A beautiful polished floor tile that is treacherous underfoot in a wet bathroom is the wrong tile regardless of how it looks, and it is the kind of mistake that is only discovered after it is laid.

Slip resistance is measured, not guessed. In the UK the meaningful figure is the Pendulum Test Value (PTV), the wet slip-resistance measure the Health and Safety Executive recognises, with a floor tile generally wanting a wet PTV that puts it in the low-slip-potential band. Manufacturers also quote an R-rating for barefoot and shod areas. The practical rule is simple: a floor tile for a bathroom is chosen for its wet slip rating first and its appearance second, and a wall tile and a floor tile are rarely the same tile for this reason. Guidance from The Tile Association on selection and the British Standards for tiling in wet areas is the reference a good tiler already works to.

How do you choose bathroom sanitaryware

Sanitaryware is the suite, and each piece carries a format decision that affects both the look and the plumbing behind it. The choices are best made together, because they share walls, services, and a style.

• The WC. A close-coupled toilet, with the cistern sitting on the pan, is the straightforward default. A back-to-wall or wall-hung WC hides the cistern in a frame or stud wall for a cleaner line and an easier floor to clean — but the concealed cistern and its frame have to be built into the wall during first fix, so it is an early decision, not a late one.
• The basin. A pedestal basin hides the pipework and needs no cabinet; a wall-hung or sit-on basin on a vanity unit adds storage and a worktop but needs the wall built to carry it. The basin and its tap are chosen together so the tap reaches and suits the bowl.
• The bath. Acrylic baths are lighter, warmer to the touch, and cheaper; steel-enamel baths are more rigid, more durable, and hold heat differently. A freestanding bath is a feature that needs floor-standing or floor-mounted plumbing planned in early; a fitted bath is the practical default.
• The shower. An enclosure over a tray, or a tiled wet-room area, changes everything behind it — a wet room needs the floor tanked and laid to a fall, which is a structural decision rather than a fitting.

The thread through all four is that the visible piece is the easy part; the wall and floor built to receive it is the part that has to be right first. A wall-hung WC chosen after first fix is a wall reopened. The way these decisions sit inside the build is the same logic that governs the kitchen, set out in the guide to kitchen units and worktops.

What WRAS approval and water efficiency mean for your choice

Two things constrain bathroom fittings in the UK beyond taste, and a buyer who knows them avoids an expensive surprise. The first is approval. Taps, valves, and fittings connected to the mains should carry WRAS approval or an equivalent, confirming they meet the Water Supply (Water Fittings) Regulations and can legally be connected — the reason a bargain tap of unknown origin can be one a plumber will not fit.

The second is water efficiency. The Building Regulations set a water-efficiency target for new dwellings, and modern sanitaryware is designed around it — dual-flush cisterns, flow-limited taps, and efficient showers all exist to meet it. For a renovation it is less a hard limit than a sensible default, and choosing water-efficient fittings cuts running cost without changing how the bathroom feels to use. Whether a particular project needs Building Regulations approval at all is set by the scope of the work, and the guidance on Building Regulations approval is the place to confirm it.

The decisions to lock before first fix and tiling

Tiles and sanitaryware feel like end-of-project choices because they are installed late, but the decisions behind them have to be made early. A concealed cistern, a wall-hung basin, a freestanding bath, and a wet-room floor all change the first-fix plumbing and the wall build — and once the walls are tanked, tiled, and the suite is plumbed, none of them can change without undoing finished work. The visible selection is late; the decision that drives the rough work is early.

The prepared homeowner chooses the suite format and the tiles before the build starts, confirms the first-fix requirements with the plumber, and orders anything with a lead time early so it is on site when the tiler and fitter need it. That is the difference between a bathroom where every fitting drops into a wall built for it and one retrofitted into a wall that was not. The full sequence is set out in the 12 phases of a renovation, and the selections that keep it on schedule are in the bathroom renovation checklist.

Frequently asked questions

Porcelain or ceramic tiles for a bathroom?

Porcelain for the floor and a wet room, ceramic for most walls if budget matters. Porcelain is denser and absorbs almost no water, which makes it the more durable choice anywhere it will get wet, and the default for floors. Ceramic is softer, cheaper, and easier to cut, and is well suited to walls that take no footfall. Many bathrooms use porcelain on the floor and ceramic on the walls for exactly this reason.

What slip rating do I need for a bathroom floor tile?

A bathroom floor tile should be chosen for its wet slip resistance, measured by the Pendulum Test Value (PTV) that the Health and Safety Executive recognises, with a floor wanting a value in the low-slip-potential band when wet. Manufacturers also quote an R-rating. The key point is that a wall tile and a floor tile are usually different products: a polished tile that looks superb on the wall can be unsafe on a wet floor, so the floor tile is selected on its slip rating first.

Should I choose a wall-hung or close-coupled toilet?

A close-coupled WC, with the cistern on the pan, is the simple default and the easiest to fit. A wall-hung or back-to-wall WC hides the cistern for a cleaner look and an easier floor to clean, but the concealed cistern and its supporting frame have to be built into the wall during first fix. That makes it an early decision — choosing it after the wall is built means opening the wall again, so it is settled before plumbing starts, not after.

Do bathroom taps need to be WRAS approved in the UK?

Taps and fittings connected to the mains water supply should carry WRAS approval or an equivalent, which confirms they meet the Water Supply (Water Fittings) Regulations and can legally be connected. It is the plumber's responsibility, but it matters to the buyer because a cheap unapproved fitting of unknown origin may be one a plumber will not install — so checking for approval before buying avoids a fitting that cannot legally go in.

Is natural stone a good idea in a bathroom?

It can be beautiful, but it is the highest-maintenance option. Most natural stone — marble, limestone, travertine — is porous and has to be sealed before use and resealed periodically to survive the water and products of a bathroom. It rewards a buyer willing to maintain it and frustrates one who is not. Porcelain now imitates stone convincingly at a fraction of the upkeep, which is why many homeowners who want the look choose a stone-effect porcelain instead.

When do I need to choose the tiles and sanitaryware?

Before the build starts, not at the end. A concealed cistern, a wall-hung basin, a freestanding bath, and a wet-room floor all change the first-fix plumbing and the wall build, and once the walls are tanked and tiled none of them can change without undoing finished work. The tiles and suite are installed late but specified early, which is why locking the formats before first fix is what keeps the project running without rework.
