The Undertile Bath Seal is a durable PVC bath sealing trim designed to create a long-lasting, watertight seal between a bath and a tiled wall. Installed beneath the bottom row of tiles, it provides a discreet, professional solution for preventing water penetration, helping to reduce the risk of leaks, damp, and mould growth in bathrooms and wet rooms.

Manufactured from high-quality rigid PVC, the seal features flexible sealing lips that form an effective waterproof barrier while accommodating slight movement between the bath and wall. By being fitted beneath the tiles, it creates a concealed finish that enhances both the appearance and performance of the installation.

Suitable for both new bathroom installations and refurbishment projects, the Undertile Bath Seal is easy to install during the tiling process and offers a durable, low-maintenance solution for protecting walls, floors, and surrounding structures from water damage. Ideal for domestic and commercial bathrooms, it helps create a hygienic, leak-resistant finish that stands up to everyday use.
