Quick Answer
This case study documents a 600 m² swimming pool renovation at a coastal resort, where existing faded ceramic mosaic was replaced with MosaicPeel glass mosaic for the waterline and porcelain mosaic for the pool floor and walls. The project required paper-faced mounting for full submerged coverage, epoxy grout throughout, and a phased 6-week installation during the resort’s off-season. Post-renovation results: water clarity perception improved by an estimated 40% due to glass’s light-reflecting properties, slip resistance confirmed at DCOF ≥ 0.60 for the pool floor, and the resort reported a 15% increase in pool-side booking inquiries within the first quarter after reopening.

The Original Pool Condition
The resort — a 120-room coastal property in the Mediterranean — had operated with its original ceramic mosaic interior for approximately 12 years. By the time of renovation, the pool showed:
- Visible glaze wear on the floor tiles, with several areas of faded color from prolonged chlorine exposure
- Water absorption concern: the original ceramic mosaic tested at approximately 4% water absorption (semi-vitreous), which contributed to mineral deposit staining that became increasingly difficult to clean
- Slip resistance below modern standards: the existing finish no longer met current wet DCOF expectations for commercial pool floors
The resort’s property management team decided on a full interior retile rather than a partial repair, given the extent of wear and the desire to reposition the pool as a premium guest amenity during the upcoming high season.
Material & Color Selection
| Zone | Material | Color | Finish | Reason |
|---|---|---|---|---|
| Pool floor (500 m²) | Porcelain mosaic | Soft sand beige | Matte | PEI-rated, DCOF ≥ 0.60, frost-proof |
| Pool walls (80 m²) | Glass mosaic | Mediterranean turquoise | Semi-gloss | 0% absorption, light reflection for water depth |
| Waterline band (20 m²) | Glass mosaic accent | White/cream | Gloss | Premium visual anchor at water surface |
| Total | — | — | — | 600 m² |
Why the hybrid approach: porcelain for the floor delivers the slip resistance and durability needed for continuous wet foot traffic. Glass for the walls and waterline delivers the light reflection that makes pool water read as vivid and inviting — a genuine visual difference that ceramic or matte porcelain cannot replicate at the same intensity.

Installation Process & Timeline
The renovation was executed during the resort’s 8-week off-season closure, with the following phased approach:
| Week | Activity |
|---|---|
| 1–2 | Drain pool, remove existing ceramic mosaic, prepare substrate |
| 3–4 | Install porcelain mosaic floor (500 m²) with epoxy grout |
| 5 | Install glass mosaic walls and waterline band |
| 6 | Epoxy grout cure period, water chemistry balancing, pool fill |
Key technical decisions:
- Paper-faced mounting was specified for all submerged glass mosaic sheets, since paper-faced mounting allows full mortar contact on the tile back after paper removal — critical for submerged applications where delamination risk is highest.
- Epoxy grout was used throughout the entire interior, not cement grout. In a saltwater-pool environment, cement grout degrades over years; epoxy grout is 100% waterproof and chemically resistant to chlorine and salt.
- Water chemistry was balanced over a 7-day period after filling before the pool was opened to guests, ensuring the new epoxy grout had fully cured before chemical exposure began.

Client Results
| Outcome Metric | Result |
|---|---|
| Water clarity perception improvement | Estimated 40% (guest feedback survey) |
| Slip resistance compliance | DCOF ≥ 0.60 confirmed for pool floor |
| Post-reopening pool-side booking inquiry increase | 15% in Q1 vs. prior year |
| Grout maintenance requirement | Zero resealing required after 12 months (vs. annual cement grout resealing previously) |
| Resort repeat booking | Yes — second resort property in the same group, 24 months later |
The resort’s general manager noted that the pool’s visual transformation was immediately apparent to guests, with several commenting specifically on how the water appeared “clearer and more vibrant” — an effect directly attributable to glass mosaic’s light-reflecting properties in the wall and waterline zones.

FAQ
Can glass mosaic be used on a pool floor?
Glass mosaic can be used on pool floors, but the finish must be slip-tested. Matte or textured glass finishes with confirmed DCOF ≥ 0.60 are suitable. Glossy glass finishes are better reserved for waterlines and vertical walls. Many professionally built pools use a hybrid approach: porcelain for the floor and steps, glass for walls and waterlines.
What grout is best for a swimming pool renovation?
Epoxy grout is the only appropriate choice for submerged pool interiors. It is 100% waterproof, chemically resistant to chlorine and salt, and does not require the annual resealing that cement grout demands in a pool environment.
How long does a pool mosaic renovation take?
For a full interior retile of a commercial resort pool (approximately 600 m²), the typical timeline is 6–8 weeks from drainage to reopening, including substrate preparation, installation, grout cure, and water chemistry balancing. This should be planned during the property’s off-season to minimize revenue impact.
Why did the resort choose to fully retile rather than patch repair?
The existing ceramic mosaic had reached a point where glaze wear, mineral staining, and slip resistance concerns were widespread across the full interior — not localized to a single zone. At that stage, patch repair costs approach full replacement costs without delivering the same visual or performance outcome.
