"Sani Building Corp installed large-format marble tile in our Brooklyn bathroom — the layout planning was meticulous and the cuts around the toilet and vanity are perfect. Grout lines are razor straight. Stunning result."
"Had them install heated floor tile in our Manhattan bathroom. They installed the Schluter heating mat, tiled over it perfectly, and the thermostat works flawlessly. Worth every penny — the warm floor in winter is amazing."
"They replaced old cracked tile in our Long Island City bathroom with beautiful hex mosaic floor tile. The pattern layout was perfect — they centered it exactly and the grout color they recommended looks gorgeous."
"Sani Building Corp tiled both our bathrooms in our Nassau County home — large format porcelain throughout. The diagonal layout in the master bath looks incredible. Clean work, no mess, and finished exactly on schedule."
"They found that our subfloor had some soft spots from an old leak before installing tile. Fixed everything properly first — new cement board, waterproof membrane, then perfect large-format tile. Exactly what you want from a contractor."
"We chose a complex Carrara marble pattern for our Brooklyn bathroom floor — book-matched tiles in a pinwheel pattern. Sani Building Corp's tile setter handled it perfectly. The precision on the pattern matching is extraordinary."
