Shop Gemma by colour
Prices are per sq ft and tile is sold by the box.
Gloss and veining, like cut stone
The finish is gloss, so the glass picks up light and throws reflections around the pool. Each mosaic has its own veining, so no two squares are quite alike.
Celestite, Hematite, Moonstone, Kyanite and Tanzanite are the blues. Peridot, Lace and Olivine are green. Gibeon, Zircon, Magnet and Galena cover grey, silver and charcoal. Quartz is white and Topaz is brown.

How to order Gemma tile
Four steps from measuring to a complete order.
1. Measure
Add up walls, floor, steps and benches in square feet, or let the Pool Tile Calculator do it.
2. Choose your colour
Open a colour and choose Get Sample ($5, credited toward your order), or order boxes if you already know the one.
3. Order whole boxes
Tile is sold by the box (13 sheets, 21.5 sq ft). Prices on the cards are per sq ft, so round up to whole boxes.
4. Add grout and adhesive
Plan one 2.5 kg container of Starlike Pro epoxy grout for every box of 25 mm tile. Set it with PowerGel S1+ on concrete.

What to buy with your Gemma tile
Adhesive
On concrete, set glass mosaic with PowerGel S1+ ($130, 20 kg), a white flexible adhesive rated for freeze-thaw. For a waterproof epoxy bond use PowerGel Pro Max ($160, 5 kg), and waterproof the shell first with SafetyGel ($320, 10 kg).
Epoxy grout
Plan one 2.5 kg container of Starlike Pro epoxy grout for every box of 25 mm tile. Starlike Pro is $160 per 2.5 kg in 19 colours. Why epoxy grout for pools.
Tools
You will need a 6 mm trowel for the adhesive and an epoxy grout float for the joints. Step by step: how to install glass mosaic tiles.
