Microcement Bathrooms
Waterproof, seamless, and grout-free. The end of bathroom tile as you know it.
The Bathroom Revolution
Why Microcement Is the Best Bathroom Surface
Bathrooms are the hardest-working rooms in any home. They face daily exposure to water, steam, humidity, temperature swings, soap, cosmetics, and heavy foot traffic. For decades, tile has been the default choice — not because it is ideal, but because nothing better existed. Microcement changes that equation entirely.
ATRIA's polyurethane-dolomite microcement system was engineered from the ground up for wet environments. Unlike acrylic-based alternatives that can soften in persistent humidity, ATRIA's modified polyurethane resin creates a closed-pore surface that is genuinely waterproof — not just water-resistant. Combined with our two-component Atriapol Antibacterial sealer, the system handles direct water contact in showers, around bathtubs, and on bathroom floors without any degradation.
The aesthetic transformation is equally dramatic. Where tile creates a grid of grout lines that visually shrink a space and create cleaning nightmares, microcement flows seamlessly across every surface — walls, floors, shower enclosures, vanity surrounds, and even ceilings. The result is a spa-like environment that feels larger, calmer, and infinitely more luxurious than any tiled bathroom.
And the best part? No demolition. Microcement overlays directly onto existing bathroom tile, meaning your renovation can be completed in days — not weeks — without the dust, noise, and disruption of a traditional gut renovation.
Microcement vs Tile
Why Microcement Beats Tile in Bathrooms
Zero Grout = Zero Mold
Grout is the #1 problem in bathrooms. It absorbs moisture, harbors mold, stains, and cracks. Microcement has no grout lines — the entire surface is sealed and impervious.
Faster Installation
A full bathroom microcement installation takes 4–5 working days. Tile demolition, setting, grouting, and curing can take 2–3 weeks. Less downtime, less mess, less disruption to your home.
No Demolition Required
Microcement overlays directly onto existing tile. No sledgehammers, no dumpsters, no dust clouds through your home. The old tile stays in place as a stable substrate.
Spa-Like Aesthetic
The seamless, monolithic surface creates a high-end spa atmosphere that tile simply cannot replicate. No visual interruptions, no busy patterns — just calm, continuous surfaces that feel luxurious.
Easier Maintenance
No scrubbing grout lines. No resealing grout annually. Wipe down with a damp cloth. The polyurethane topcoat repels water, stains, and soap scum.
Design Continuity
Run the same microcement from shower walls to bathroom floor to vanity surround. No transition strips, no material changes. One material, one color, one seamless experience.
Applications
Every Bathroom Surface, Seamless
Shower Walls & Floors
The ultimate shower surface. A code-compliant waterproofing membrane beneath the microcement, the ATRIA Atriafloor cycle above, and the two-component polyurethane antibacterial topcoat on top — a completely waterproof enclosure by design. No grout to clean, no tile to re-caulk, no mold hiding in corners. The shower becomes a seamless, spa-like cocoon. Anti-slip additives in the topcoat ensure safety on wet shower floors.
Bathroom Floors
Seamless bathroom floors that flow from the bedroom threshold into the shower — no curbs, no transitions, no level changes needed. Perfect for curbless shower designs and universal accessibility. The waterproof system handles standing water, splashes, and daily wet-area use without degradation.
Walls & Vanity Surrounds
Wrap your entire bathroom in one continuous finish — walls, vanity surrounds, built-in niches, and even tub surrounds. The monolithic surface creates a serene, clutter-free environment. Custom colors mean your bathroom can be warm and inviting or cool and contemporary — your choice.
Tub Surrounds & Wet Rooms
Freestanding tub surrounds, wet room enclosures, and half-wall partitions all benefit from microcement's seamless waterproofing. Create a complete wet room with continuous surfaces from floor to ceiling — the European bathroom standard, now achievable in Dallas homes.
Waterproofing System
Six Layers of Protection
Bathrooms demand the highest level of waterproofing. Our six-layer system leaves nothing to chance.
Substrate Preparation
Existing tile or concrete is cleaned, degreased, and any loose material removed. Cracks are repaired with flexible filler.
Waterproofing Membrane
In direct wet areas (shower stalls, wet rooms), a liquid waterproofing membrane is applied as an additional safety layer beneath the microcement system.
Bonding Primer
Primerquartz (for walls) or Atriafloor Primer (for floors) creates the adhesion foundation for the microcement layers.
Rasante Base (Floors Only)
Bathroom floors receive two coats of Atriafloor Rasante One for structural reinforcement under foot traffic.
Microcement Finish
Two coats of SuperTitanium BC — the bi-component polyurethane formula with 32 ± 2 MPa compressive strength (EN 1015-11) and the highest mechanical resistance in the PURO line, engineered for wet-area and high-traffic use.
Polyurethane Seal
Two coats of Atriapol Antibacterial two-component polyurethane topcoat. Waterproof, stain-proof, and UV-stable. Anti-slip additive included for wet floors.
Tier Pricing
Bathroom Tier Pricing
Most bathrooms fall into the Standard tier because tile removal and backer-board prep is standard. Full Build applies to MDF or plywood vanity fronts, radiant-heat floor substrates, and commercial wet-zone exposure.
| Bathroom Size | Standard Tier (all in) |
|---|---|
| Powder Room (≈35 sf) | Project minimum applies |
| Medium Bath (≈80 sf) | $2,500–$3,800 |
| Full Bath + Shower (≈150 sf) | $4,200–$6,500 |
Fast
Sound substrates in good condition — uncommon for bathrooms.
Standard
Tile removal, backer-board prep, gypsum self-leveler. The tier most bathrooms fall into.
Full Build
MDF or plywood vanity fronts, radiant-heat floor substrates, commercial wet zones. Includes Glass Mat 300 mesh, two Cementius Pasta build-up coats, and extended cure protocol.
Tier is determined by substrate and wet-area spec, not by client choice. Surface-level ranges: floors $19–$24/sf Standard, walls $23–$28/sf Standard. Full-project all-in pricing reflects the blended floor + wall + shower system.
Common Questions
Microcement Bathroom FAQ
Absolutely — built as a complete assembly. A code-compliant liquid waterproofing membrane (typically ARDEX 8+9 or equivalent, installed with reinforcing fiberglass mesh) goes beneath the microcement as the actual water barrier. On top, the ATRIA Atriafloor cycle — Atriafloor Primer, two coats of Atriafloor Rasante One, two coats of SuperTitanium BC, and two coats of the New Atriapol W antibacterial topcoat — delivers the sealed, closed-pore, decorative finish. The complete system exceeds the performance requirements for shower stalls and wet rooms, and matches the spec European architects write for boutique hotel wet rooms.
Yes — this is one of the biggest advantages. Microcement bonds directly to existing tile, eliminating the need for demolition. The tile stays in place as a stable, flat substrate. The total overlay thickness is only 2–3mm, so it rarely affects door clearances or fixtures. This saves thousands in demolition and disposal costs.
Simply wipe down with a damp cloth or soft sponge and a pH-neutral cleaner. No scrubbing grout lines, no special sealers needed annually. Avoid abrasive cleaners and acidic products. The polyurethane topcoat can be refreshed every 5–8 years with a maintenance coat — no demolition, just a fresh layer of sealer.
Microcement is a flexible material — it moves with the building. Unlike rigid tile and grout that crack when a building settles, microcement's polyurethane composition provides elasticity. Proper substrate preparation and crack treatment during installation prevent stress cracking. ATRIA microcement has been installed in thousands of bathrooms across Europe without structural issues.
