Can you tile over my existing 12x12 ceramic?

Sometimes, and it is worth asking because it saves the demolition cost and the dust entirely. It works when the existing tile is soundly bonded everywhere — we tap across it listening for hollow areas — and when the added height does not cause problems. In these houses height is usually the deciding factor: dishwasher clearance, exterior door swing, and the transition to adjoining rooms all have to work with a floor that is a bit higher than it was.

Why does adding floor height matter so much in a 1990s tract house?

Because the clearances were tight to begin with. Raise the kitchen floor and the dishwasher may no longer slide out from under the countertop, which turns a future repair into a countertop job. Exterior doors that cleared by a quarter inch start dragging. And a transition to the next room that was flush becomes a step, which is both a trip point and something you notice daily. All manageable if planned for, all expensive as surprises.

What tile & stone involves in Spring

Almost all the tile work here starts as removal. The 1980s and 1990s subdivisions that dominate this area were built with 12x12 ceramic as the standard hard surface — entries, kitchens, breakfast rooms, baths — and that tile is now at end of life aesthetically even where it is still sound. Taking it out is the bulk of a Spring tile job.

The question that decides the cost is whether it comes out or gets covered. Where the existing tile is well bonded across the whole area with no hollow spots, tiling over it is legitimate: it saves the demolition, the dust, and the days. What rules it out in these houses is usually height. Adding a layer raises the finished floor, and in a 1990s tract house that frequently means the dishwasher no longer clears the countertop when you try to remove it, exterior doors bind, and the transition to adjacent flooring becomes a step rather than a threshold. Those are not small problems and they are much cheaper to discover before the work than during it.

So we sound the existing tile for hollow areas and check every appliance clearance and door swing before recommending either path. Where the tile is releasing in places, going over it just relocates the failure. We would rather do the demolition and the grinding properly and hand over a floor that is not sitting on somebody else's mortar.

The job we run most here

Removing 12x12 ceramic from an entry, kitchen and breakfast area in a 1990s two-story, grinding the residual thinset, and setting large-format porcelain.

What it costs in Spring

Tile runs $10–$20 installed. Demolition and thinset grinding is the substantial extra here. Where tiling over the existing floor is genuinely viable it saves real money — but appliance clearances and door swings have to be checked first, not afterwards.
