Renovate the shower. Keep the tile underneath.
A seamless, spa-like shower — installed over your existing tile.
A seamless surface of granite and acrylic resin — an innovative trowel-applied system with the strength of stone, the flex of resin, and a body that seals out water. Installed over your existing tile in a remodel — no demolition, no waterproofing redo — or straight onto waterproofed board in new construction. One continuous, grout-free shell for shower walls, ceilings and floors. Get your complete material kit and price in under 60 seconds.

Step 1Enter your dimensions
Build the project surface by surface - start with the shower, add what the room needs.
Calculates three walls plus the ceiling and assumes one side is glass or a door.
Calculated from the shower footprint and finished with the Anti-Slip R-11 topcoat.
Carry the same surface across the vanity walls and the bathroom floor - one shell, no transitions, no grout.
Enter wet walls and floors separately so the calculator can include the correct wet-area and anti-slip products.
Enter the combined area you plan to finish. We apply the material allowance automatically.
Step 2Pick your finish
Every finish takes any movement - calm and modern to boldly artistic. The trowel writes the pattern; the finish sets the grain.
Microterrazzo blend
White base, tintable with any of our colors - lighter shades keep the quartz visible.
Step 3Pick your color

The full standard palette - over 50 colors in warm, cool and earth tones.
Step 4Pick your sheen
Choosing Matte? Every matte build starts with Armourcoat Satin as its base coat - the satin base is still in your kit, so you can keep a satin sheen if you change your mind.
Exterior and Micromosaic presets use a fixed matte finish. Monolith retains its natural stone finish without a sealer.
Step 5Pick your protection level
The level sets the thickness of the build: Maximum simply adds more material and sealer to your kit for harder-working surfaces. Nothing else changes.
The selected preset uses a fixed protection build.
In their words
“The anti-crack memory resin holds up every time — no hairline cracking, no callbacks, no touch-ups.”
“A seamless, jointless finish without concerns about underperformance or discoloration — durability and design, even in wet areas.”
“Our walls became one seamless, softly textured shell — the whole room reads as if carved from a single material.”
“On new builds it delivers a flawless, jointless finish that’s highly durable and crack-resistant — a reliable system that adds value across the board.”
“With over 10 years applying microtoppings, this is the strongest material I have used — a flawless, seamless finish every time.”
“Top-tier material with a true professional standard. Durable, seamless and built for long-term use.”
“A seamless, waterproof-ready surface with no grout lines — and the result has held up beautifully.”
A smarter way to renovate showers — without the waterproofing redo.
Traditional tile-replacement renovations carry hidden costs: demolition, waterproofing redo, tile removal, waste handling, permit delays, and weeks of downtime. Cement-based microcement systems can install over tile too, but introduce their own risks — shrinkage cracking, efflorescence, color shift during cure. TERRAZZO GraniTech avoids both paths.
Percentage savings hold across markets. Labor rates differ between South Florida, New York, Los Angeles and Chicago, but the relative advantage stays consistent — and the patented granite + resin chemistry is what makes the over-tile install possible at all. Building new or gutting to the studs? The same system installs over waterproofed cement board — one material, pan to ceiling. Request a wet sample to see the system installed in real shower conditions.
What you eliminate
The finishes
The hand writes the movement. The finish sets the grain.
Every TERRAZZO GraniTech finish arrives as a ready-to-use paste — and every one of them takes any movement. Troweled flat, it reads modern and mirror-calm. Moved loosely, it drifts like limewash. Worked boldly, it becomes artistic, sculptural texture. What you choose here is not the pattern — it’s the grain beneath it. The sealer sets the final note: matte, satin, or a subtle semi-gloss.
The surface
Depth built into the surface.
Color is the least of it. Beneath every movement your applicator writes, TERRAZZO GraniTech builds a dense, cement-free granite + resin body over your prepared tile — thin as a coin, sealed against water, engineered to keep the pattern exactly as the trowel left it. The pattern is yours. The permanence is built in.

Questions
Frequently asked questions
Is TERRAZZO GraniTech a microcement alternative?
Yes. It delivers a similar seamless aesthetic, with a granite-aggregate + resin matrix designed for durable continuous surfaces — more flexible than many cement-based microcement systems and inherently water-resistant prior to sealers.
Can it go over existing shower tile without demolition?
Yes. It’s applied in thin layers over properly prepared existing tile — no demolition, no waterproofing redo, no waste hauling. The surface you have becomes the base for the shower you want.
Can I use it in new construction or a full remodel?
Yes. In a remodel it installs over existing tile; in new construction or a full gut, it installs over waterproofed cement board or another code-compliant substrate, with the waterproofing membrane of your choice beneath. One system, pan to ceiling.
Is it waterproof even before sealers?
The cured surface is inherently water-resistant before sealing. The Armourcoat wet-area sealers complete the system for showers and steam.
Do I need waterproofing under it in showers and wet rooms?
Over existing tile, the sound waterproofing beneath keeps working — that’s the point of not demolishing. On new builds, use waterproofed cement board or another code-compliant substrate with the waterproofing membrane of your choice.
Are the floors slippery?
No — shower pans and bathroom floors finish with the Anti-Slip Matte PU topcoat, certified R-11 slip resistance.
What surfaces can it be applied to?
Existing tile, cement board, drywall and plaster — properly prepared and primed.
