Most people choose bathroom tiles the same way they choose paint: stand in a showroom, fall in love with a colour, then hope it behaves itself once it’s in a steamy room with shampoo, limescale, and wet feet.
Tiles can absolutely look great — but if you want a bathroom that still feels nice (and safe) in five years, there are a few boring-sounding details that matter more than the pattern.
1) Slip resistance: don’t guess — check the rating
If you’ve ever stepped out of a shower onto a glossy tile and done that little panic shuffle, you already know why this is top of the list.
In the UK, slip resistance is often shown as an R rating (you’ll see things like R9, R10, R11). As a rough rule:
- R9: common indoors, can be fine in low-splash areas
- R10: a safer bet for bathrooms, especially family homes
- R11: grippier, often used where floors get properly wet (wetrooms, some shower zones)
A few real-world notes:
- Small kids + glossy tiles is a classic “looks nice, feels like an ice rink” combo.
- Textured tiles can be safer, but the wrong texture can turn into a dirt trap (more on that below).
- If you’re doing a wetroom, treat the whole floor like a “shower zone” — because it is.
If you’re unsure, ask the supplier for the slip rating and tell them exactly where it’s going (main floor, shower tray area, wetroom, etc.).
2) Cleaning: grout is the real maintenance job
Here’s the bit nobody wants to hear: tiles are easy to clean — grout is not.
If you want a bathroom that stays looking sharp without turning into a weekend hobby, think about:
Tile size (bigger tile = less grout)
- Large-format tiles mean fewer grout lines, which usually means easier cleaning.
- Tiny mosaics look great, but they’re basically “more grout than tile” — and grout is where soap scum and discolouration show up first.
Tile finish (matte vs glossy)
- Glossy tiles can wipe clean easily, but they show water marks and streaks.
- Matte tiles hide marks better, but some matte finishes can “grab” dirt if they’re very textured.
Colour choices (be honest about your lifestyle)
- White grout looks amazing… for about five minutes.
- Mid-tone grout colours (light grey, warm grey) are often the sweet spot for real homes.
If you’ve got hard water in Hertfordshire (and most homes do), plan for limescale and water marks. Choosing finishes and grout colours that don’t highlight every single splash will save you a lot of frustration.
3) Longevity: what fails isn’t usually the tile
Most tile “failures” we see aren’t because the tile was cheap. They happen because something underneath wasn’t done properly.
The three big longevity factors
- Preparation: flat, solid substrate; correct boards in wet areas; no movement.
- Waterproofing: especially in showers and wetrooms. If you’re doing a walk-in shower, don’t assume tiles alone are waterproof.
- Adhesive + grout choice: using the right products for the tile type and the room (and not mixing random brands because they were on offer).
If you want tiles that last, spend less time obsessing over the exact shade of beige and more time making sure the installer is treating the wet areas properly.
4) Safety and comfort: cold feet, sharp edges, and “toe-stub” corners
A few practical things that don’t come up in Pinterest boards:
- Underfloor heating changes what feels “nice” underfoot. Without it, some tiles can feel freezing most of the year.
- Rectified edges (very sharp, crisp edges) look modern, but they can be less forgiving if your walls/floors aren’t perfectly straight.
- Tile edges and trims matter. A good trim detail looks tidy and protects corners from chips.
5) Where to spend your money (and where not to)
If you’re trying to keep a budget under control, here’s a sensible way to think about it:
Worth spending on
- Floor tiles (because slip resistance and durability matter)
- Waterproofing system in wet areas (wetrooms / walk-in showers)
- Good grout (and a colour that won’t make you miserable)
You can often save on
- Wall tiles in low-splash areas (they don’t take the same abuse)
- Feature strips and trendy finishes (they date faster than you think)
6) Quick “tile choice” checklist (use this in the showroom)
- What’s the slip rating (R rating) for the floor tile?
- Is this tile going in a wetroom / shower zone or just the main bathroom floor?
- How many grout lines will I be living with (tile size)?
- Is the surface easy to wipe or very textured?
- What grout colour will still look decent after 12 months of real life?
- What’s the plan for waterproofing behind the tiles?
When to ask a pro (before you buy 25 boxes of the wrong thing)
If you’re planning a bathroom renovation in Harpenden, St Albans, Radlett, Welwyn Garden City, Borehamwood, Hemel Hempstead, Berkhamsted, or Leighton Buzzard, it’s worth getting quick advice before you commit to a tile that’s going to be slippery, high-maintenance, or awkward to install.
A good installer will help you match the tile to:
- The room layout (including falls/drainage for wetrooms)
- Your household (kids, older relatives, rental vs forever home)
- The right prep and waterproofing system
