Bathrooms are the best argument for stained concrete that nobody makes. The room is small, so material cost barely registers; it is wet, so a sealed monolithic floor with no grout lines is genuinely better than tile; and it is the one room where a bold color is a decision rather than a commitment. Five customer bathrooms below, in five different products.
A bathroom floor before and after EverStain™ in Black and Seagrass.
Rebuilding after a flood, in Seagrass and Black
After Hurricane Ian flooded their home, these owners needed flooring that was cost-effective, durable and worth looking at. They considered wall-to-wall tile and chose stained concrete instead. The colors were deliberate — Seagrass and Black, as a tribute to the ocean water that had come through the property.
Their conclusion after learning the skill from scratch was that thorough prep work and patience are what decide the result. They sealed with AcquaSeal™. More of these colors in the Seagrass and Black galleries.
An overlay first, then Coffee Brown at four dilutions
This is the most technically interesting bathroom on the page. The slab was rough, so a concrete overlay went down first to smooth it — and then the color was built in layers using the same stain at four different strengths: Coffee Brown at 2:1, 5:1, 8:1 and 10:1, with Malayan Buff at 10:1 as a final overspray across the whole floor. Every coat went on while the floor was still wet.
Diluting one color rather than buying four is a technique worth understanding. It gives you a tonal range that reads as depth instead of as separate colors, and it costs one bottle. The owner reported the result was far better than they had imagined.
The finished floor — one color at four dilutions, plus a final buff overspray.
Azure Blue, in a bathroom
A bathroom floor acid stained in Azure Blue — the boldest colorant we make, in the room where you can get away with it. Acid stain reacts with the slab, so the blue is mottled rather than flat. More in the Azure Blue gallery.
Dye, on a damaged floor
Where a floor is damaged rather than merely plain, Vibrance™ Dye is the better tool — Light Slate, Stormy Gray and White layered over one another. Dye is more opaque than acid stain, so it evens out a floor with history in it. The full method is in how to apply concrete dye.
Charcoal colored sealer, for a sophisticated finish
The simplest route of the five: AcquaTint™ in Charcoal, which colors and seals in one step. Two coats plus wax. Step-by-step in how to apply colored concrete sealer.
A basement bathroom floor before and after Charcoal AcquaTint™, polished and waxed.
The same bathroom after the hard-troweled floor pre-treatment.
