The microcement shower embodies the contemporary bathroom: a continuous surface, with no tiles or grout, for a streamlined and high-end space. The floor, walls and shower tray are clad in the same mineral material, ideal for a walk-in shower. Clavel Rénovation creates waterproof and durable microcement showers.
Are you starting from scratch and want to create the shower itself — shower tray, waterproofing, drainage? It's this way.
Technical specifications: continuous joint-free mineral surface • essential structural waterproofing of the substrate BENEATH the polished concrete • treatment of junctions and singular points • surface water-repellent protection • application in compliance with the system.
A seamless shower, from floor to ceiling
Without tiles, the polished concrete shower eliminates grout lines, those hard-to-clean areas prone to mould. The result is a seamless, open and easy-to-maintain shower. The colour and finish can be chosen freely to create a zen, mineral or more sophisticated ambience.
Waterproofing: the golden rule for a successful shower
Key point: sealed waxed concrete resists water, but it does not replace the waterproofing of the substrate. A reliable shower first requires structural waterproofing applied beneath the waxed concrete, careful treatment of junctions (corners, shower tray, drainage), and then water-repellent surface protection. Carried out according to professional standards, these steps guarantee a healthy and durable shower, free from leaks.
A specific wet-room expertise
Polished concrete in a wet room cannot be improvised: preparation, waterproofing, application and protection must be mastered. Clavel Rénovation puts its experience at the service of your shower and bathroom projects, in the Var and throughout the PACA region.
Our polished concrete showers in the Var
Poured concrete is applied in thin layers directly onto the substrate once waterproofing has been carried out underneath: no demolition, no tiles to lift, and above all, no joints across the entire surface. Floor, walls, bench and shower tray form a single, continuous skin. This is what makes all the difference in use: nothing left for water to seep into, nothing left for limescale and mould to take hold of. The colour is chosen before application — from white to taupe grey, via sand tones — and continues seamlessly from one wall to the next.
Frequently asked questions about microcement showers
Is a polished concrete shower really waterproof?
Yes, provided it relies on a structural waterproofing system installed beneath the waxed concrete, rather than on the waxed concrete alone. The waxed concrete provides the decorative finish, while the waterproofing is ensured by the technical layer underneath. This is a crucial point highlighted in particular by the’Agence Qualité Construction in its information sheets dedicated to walk-in showers.
How to maintain a microcement shower?
Routine cleaning with soapy water is sufficient, without abrasive or acidic products which could damage the protective varnish. Periodic re-impregnation, depending on use, helps maintain the appearance and waterproofing of the finish over time.
Can you install a polished concrete shower in an existing bathroom?
Yes. After removing the old tiling or covering in the shower area to restore reliable waterproofing, the waxed concrete is applied to the prepared screed or shower tray, in continuity with the rest of the bathroom.
Is the polished concrete shower tray slippery?
The finish can be adapted with a slightly more textured feel or an anti-slip treatment in the shower tray area, combining a mineral aesthetic with everyday safety. This option is particularly recommended in households with children or elderly people.
What is the lifespan of a polished concrete shower?
Well crafted and maintained, a polished concrete shower retains its appearance and waterproofing for many years. Longevity depends above all on the quality of the waterproofing applied beforehand and on following maintenance instructions, far more than on the polished concrete itself. This is why Clavel Rénovation attaches as much importance to substrate preparation and the installation of waterproofing as to the polished concrete finish itself, ensuring a reliable shower for the long term.
