Yes! All our marble tiles and mosaics are suitable with underfloor heating.

All marble products are suitable for bathroom and shower use. Please seal the product upon installation.

Yes, we highly recommend dry laying your marble tiles before fixing them in place. Marble is a natural stone, and each tile is unique in its veining, tone, and pattern. Unlike man-made tiles, marble pieces are not identical, which is part of their beauty.

Dry laying means arranging all the tiles on the floor before applying adhesive, so you can:

  • Visualise the overall layout
  • Balance colour and pattern variations
  • Ensure the best placement of each tile


Skipping this step can lead to an uneven appearance, as tiles placed at random may clash in tone or pattern. Taking the time to dry lay ensures a more harmonious and professional finish.

Yes. All natural stone products, including marble, limestone, and onyx, require sealing to maintain their appearance and durability.

We recommend sealing the tiles after installation, once the adhesive is fully dry. This protects the marble from grout staining. After grouting, allow the grout to cure, then clean the tiles thoroughly and apply a final coat of stone sealer to protect both the tile and grout.

To keep your surfaces in top condition, reseal every 1–3 years, depending on usage and wear.

We recommend using the grout we supply. These Mapei products are specifically formulated for marble and high-end materials, ensuring the best finish and long-term performance.
We recommend using the adhesive listed below, which we supply. It is specifically suitable for marble, compatible with underfloor heating, and features a rapid setting time, essential, as the adhesive must be fully dry before sealing or grouting.
We recommend using a wet saw with a premium diamond blade.
We strongly advise that you do not book a tiler, plumber or tradespeople before your order arrives and we recommend you receive and check items from us before making any arrangements.
