Microcement or Tiles for Your Bathroom?

Microcement gives you a seamless, grout-free bathroom that tiles cannot match for that particular minimal, poured look. Tiles give you a more forgiving, lower-maintenance surface that is far easier to repair and, in a wet shower, simply safer over the long run. Neither is the right answer for every room. The deciding factors are where the water is, how much maintenance you are willing to do, and, above all, whether the waterproofing underneath is done properly. That last point is where most of the failures I get called to fix actually come from.

Key takeaways

• Microcement is a decorative coating, not a waterproofing layer. It still needs tanking underneath.
• The seamless look is real and genuinely modern, but it comes with a re-sealing commitment.
• Tiles win for wet shower zones, local repairability, and long-term low maintenance.
• Most microcement failures trace back to skipped tanking or a moving substrate, not the product itself.

What is microcement, really?

Microcement is a thin, cement-based coating troweled over walls and floors to give a continuous, jointless surface. It is typically only a couple of millimetres thick, applied in layers over a primed and reinforced substrate, then sealed. The appeal is obvious: no grout lines, a soft mineral texture, and a calm, modern finish that reads as one piece rather than a grid.

That is the honest selling point, and I will not talk you out of the look. It suits a certain kind of pared-back bathroom, and on the right surfaces it does something tiles cannot. The trouble starts when people assume that because it is cement-based and arrives as a solid skin, it must be waterproof. It is not.

Is microcement waterproof?

No. Microcement is a finish, not a tanking system. In a wet area it needs exactly the same waterproofing behind it that a tiled wall does: a proper membrane such as Mapei Mapelastic, BAL Tank-it, or a Schluter Kerdi system, fully sealed at the corners and the floor joint. The microcement goes on top of that, and a sealer goes on top of the microcement.

If a fitter tells you microcement removes the need to tank a shower, walk away. The continuous surface looks reassuring, but water migrates through any micro-crack or worn sealer the same way it migrates through grout, and once it is into the wall behind, you see nothing until the plasterboard is soft. For why this single step decides the whole job, see what is tanking.

Where microcement works, and where it fails

Microcement is at its best away from constant, direct water:

• Vanity walls and feature walls. Out of the splash zone, it looks superb and lasts well.
• Bathroom floors with good drainage and decoupling. Workable, provided the substrate is sound and the sealer is maintained.
• Cloakrooms and powder rooms. Low water exposure, high visual payoff.

Where I would steer you to tiles instead:

• The shower enclosure and wet floor. This is where sealer wear and any hairline cracking hurt you most. A properly tanked and tiled wet room is the more reliable answer here.
• Suspended timber floors. Microcement needs a stable base. On the moving timber floors common in older Bromley and Beckenham homes, the substrate must be decoupled and rock solid first, or the coating will crack.

Microcement vs tiles on maintenance and repair

This is the part that gets glossed over. A tiled surface is largely fit-and-forget. Keep the grout sound and the silicone joints fresh and it will sit there for decades. If a single tile chips, you swap that tile.

Microcement is different on both counts. The sealer wears, particularly on floors and in the shower, and it has to be renewed on a schedule to keep the surface watertight and stain-resistant. And because the finish is continuous, you cannot repair a worn patch or a crack in isolation. The whole area usually has to be re-coated to blend, which is a far bigger job than lifting one tile. If you like the idea of the look but not the upkeep, a large format porcelain in a stone or concrete effect gives you most of the seamless feel with the repairability of tile. See large format tiles, what to know.

Does the seamless look need real concrete, or can tiles fake it?

Quite well, actually. Modern large format porcelain tiles come in convincing concrete and microcement effects, and with narrow grout joints and a colour-matched grout, the grid recedes to the point where most people do not read it as tiled. You get the calm, mineral appearance, plus a surface that is fully waterproof once tanked, easy to clean, and repairable tile by tile. If your real goal is the look rather than the specific troweled texture, this is the route I most often recommend.

So which should you choose?

Choose microcement if the seamless, grout-free finish is the whole point for you, the area is not a constant wet zone, and you are genuinely willing to re-seal on a schedule. Choose tiles if you want the lower-maintenance, more forgiving, more repairable surface, and especially for the shower itself. Either way, the non-negotiable is the waterproofing underneath. I have lifted plenty of failed microcement off walls that were never tanked, and the wall behind was always worse than the owner feared.
