Tadelakt is the polished Moroccan lime plaster people fall for after seeing a seamless, waterproof bathroom with no tile grout in sight. It is also one of the few finishes where the price per square metre says almost nothing on its own, because labour, substrate and room size swing the total enormously. Here is an honest breakdown of what it costs, what drives the number, and where homeowners in and around Radlett usually get caught out.
For supply and fit, most genuine tadelakt work in this area lands somewhere between £180 and £350 per square metre, with wet areas such as shower enclosures typically sitting at the upper end. That figure normally covers the lime plaster itself, the multiple coats, the compression and polishing with a river stone, and the olive soap treatment that cures the surface into a water repellent finish.
Those ranges assume a sound, prepared background. If we need to hack off failed plaster, install a cement or lime render base coat, or make good around a newly moved shower tray, that preparation is priced separately and can add £40 to £90 per square metre. Very small areas often carry a minimum charge, because a 2m2 splashback still needs the same setting up, drying time and return visits as a much larger wall.
Tadelakt is sold by the square metre but bought with time. A skilled plasterer covers far less ground per day than with standard skimming, because the material is applied thin, allowed to firm up, then compressed and burnished by hand at exactly the right moment. Miss that window and the polish will not take, so the work cannot be rushed to fit a cheaper day rate.
Material origin matters too. Authentic Moroccan lime from Marrakech behaves differently from a European hydrated lime blend or a synthetic lookalike marketed as tadelakt. Pigments are another variable: earthy ochres and warm whites are inexpensive, while deep charcoals, blues and strong greens need far more pigment and push the material cost up noticeably.
Finally, shape drives price. Flat, square walls are quick. Curved niches, arched reveals, window returns, seamless internal corners and a fitted basin or bench all take disproportionate time, and a bathroom full of those details can cost nearly double one with plain walls of the same area.
Be wary of a price given over the phone from a photo. Any plasterer working with lime needs to see the background, because tadelakt fails when it is applied over gypsum skim, plasterboard without a suitable base, or a damp wall that has not been diagnosed. Older properties around Radlett, Shenley and Aldenham often have solid walls where lime is a genuinely good match, but they need checking rather than assuming.
A clear quote should name the material and its origin, state the number of coats, confirm the base coat build up, and set out drying and curing time between stages. Expect a bathroom to take roughly five to ten working days from first coat to usable, and longer in winter when drying slows. It should also say what happens with the shower tray junction and any pipework penetrations, since those are the points where poorly executed tadelakt leaks.
Tiling a bathroom to a good standard in Hertfordshire is often £120 to £200 per square metre fitted, plus tiles, so tadelakt is genuinely more expensive up front. What you buy is a joint free surface with no grout to discolour, a soft depth of colour that changes with the light, and a finish that can be repaired and re-waxed rather than ripped out.
It suits people who want the look and will maintain it. Tadelakt needs a pH neutral soap rather than bleach or limescale remover, and a shower area benefits from re-soaping every year or two. If a household will not do that, honest advice is that a good large format tile or a quality microcement may serve better. We would rather say so at the quoting stage than hand over a finish that gets scrubbed with the wrong product in month three.
Not directly. It needs a suitable base, usually a cement or lime based render coat over a waterproofed and reinforced board, which is why any sensible quote follows a site visit rather than a photo.
A well applied and properly soaped shower can look good for fifteen years or more, provided it is cleaned with pH neutral soap and re-treated every year or two. Damage is usually repairable in place rather than needing full replacement.
Yes, proportionally. A 3m2 splashback costs far more per square metre than a full bathroom, because the preparation, curing time and repeat visits are almost identical regardless of size.
