Disma Onyx White Porcelain Tile starts at $8.99 per square foot installed in Fort Myers — a marble-look floor from Alon Floors’ Porcelain collection that pairs a white-and-cream field with the natural veining character of onyx stone. It’s available in glossy, matte, and polished finishes, so you can dial in the sheen level that suits your space. Large-format sizes give it a clean, open feel that works especially well in Southwest Florida’s bright, open-plan homes.
Porcelain is one of the most practical flooring choices for coastal Southwest Florida. It sheds humidity without swelling, sits flat on concrete slab foundations without any acclimation period, and holds up to the sandy grit that tracks in from the beach. Salt air doesn’t affect it. Whether the home runs air conditioning year-round or sits dark and warm for months at a stretch while owners are up north, the tile won’t warp or shift.
The Disma Onyx White works well in entryways, kitchens, main living areas, and bathrooms — anywhere foot traffic is real and moisture is a factor. Its glossy and polished finish options are especially popular in living rooms and primary baths where light reflection adds visual depth.

Flooring Queen installs Disma Onyx White Porcelain Tile at $8.99 per square foot, and that price covers the full scope of a standard job: delivery to your home, removal of the existing floor covering, routine subfloor preparation, the tile installation itself, new baseboards, transition strips between rooms, and cleanup and debris removal when the crew leaves.
Some scopes cost more. If the subfloor needs significant leveling beyond standard prep, if you’re adding stair nosing, or if the layout calls for diagonal runs, custom borders, or intricate patterns, those are quoted separately. Get started with a free in-home measurement — you’ll receive a written quote with exact square footage and a clear line-item breakdown before any work begins.
Luxury vinyl plank is the most common alternative shoppers consider when they’re deciding between a hard tile and a resilient floor. LVP wins on comfort — it’s warmer and softer underfoot and much quieter without underlayment. It also installs faster and costs less. If budget or a tight timeline is the priority, LVP is a legitimate choice.
Where porcelain pulls ahead: it’s genuinely harder, it won’t scratch or dent from furniture, it handles standing water with zero concern, and it doesn’t fade or soften in direct sun — something Florida south-facing rooms demand. Disma Onyx White’s marble look also reads more authentically in person than a printed vinyl plank surface. Neither product requires refinishing; both are low maintenance. The choice usually comes down to how much you care about underfoot feel versus long-term hardness.
| Disma Onyx White | Luxury Vinyl Plank | |
|---|---|---|
| Water resistance | Fully waterproof, zero absorption | Waterproof surface, seams can allow seepage |
| Scratch resistance / wear layer | Extremely hard ceramic surface | Wear layer varies; can scratch or dent |
| Comfort underfoot | Hard and cool; no give | Softer, warmer, quieter |
| Installed price | $8.99 / sq ft installed | From $3.99 / sq ft installed |
| Best room | Kitchens, baths, main living areas | Bedrooms, living rooms, light-traffic areas |
Sweep or dust-mop Disma Onyx White regularly to pick up the sand and grit that scratches glossy and polished surfaces over time. Damp-mop with a pH-neutral cleaner — avoid acidic products like vinegar-based solutions, which can dull the finish and degrade grout over repeated use. The grout joints should be sealed after installation and resealed every one to two years depending on traffic and exposure; a penetrating grout sealer (brands like Aqua Mix or Miracle Sealants work well) keeps staining in check. Avoid steam mops on polished finishes, as repeated high heat can affect the surface sheen. For technical guidance, see the Why Tile — Ceramic Tile Distributors Association consumer guide.
Yes, grout should be sealed after installation and resealed every one to two years in high-traffic or wet areas. Unsealed grout absorbs staining agents — coffee, cooking grease, mop water — and discolors quickly. A penetrating sealer like Aqua Mix or Miracle Sealants 511 is a straightforward DIY task that takes under an hour for most rooms.
Larger tiles like the 600×1200 plank format create fewer grout lines, which makes a room feel more open and continuous — a real advantage in Southwest Florida’s open-plan layouts. The 800×800 square format is more traditional and easier to lay without lippage concerns. Both sizes require a flat, well-prepared substrate; larger tiles are less forgiving of subfloor variation.
In Southwest Florida, porcelain’s thermal mass actually works in your favor — the tile stays at room temperature in an air-conditioned home and doesn’t feel dramatically cold the way it might in a northern climate with concrete slab floors in winter. Most Fort Myers homeowners find it comfortable year-round, especially barefoot in summer.
Day-to-day costs are minimal — a pH-neutral floor cleaner and a microfiber mop cover routine cleaning. Unlike hardwood, porcelain never needs refinishing. The one recurring cost is grout sealer, applied every one to two years; a bottle runs $15 to $30 and covers most standard rooms. No special equipment or professional service is required.
Porcelain tile handles seasonal vacancy better than almost any other flooring material. It doesn’t absorb humidity or off-gas in heat, it won’t warp when the air conditioning is turned up or off, and it won’t shift on a concrete slab during Florida’s summer humidity swings. Coming back to find the floor exactly as you left it is typical with porcelain.
Concrete slab is actually the ideal substrate for porcelain tile, and it’s the dominant foundation type across Southwest Florida. Porcelain bonds directly to slab with a proper thinset, doesn’t need a floating installation method, and has no acclimation requirements. As long as the slab is flat and free of significant moisture intrusion, this is a straightforward, stable installation.
Large-format tile is unforgiving — lippage, hollow spots, and crooked grout lines all show. Our crew runs SLC where it’s needed and lays tile to the manufacturer’s offset spec. Twenty years installing in Fort Myers. Call (239) 763-0770.
