Bath and shower sealants, often called sanitary sealants, are essential for keeping wet areas properly sealed and protected from water ingress. Whether you’re working on a full bathroom refit or just resealing a shower or sink, these products help create a watertight finish that stands up to daily use. Typically used around baths, showers, sinks and toilets, sanitary sealants bond well to tiles, ceramics, glass and metal, helping prevent leaks and moisture getting into joints. Many are also mould-resistant, which helps keep areas in bathrooms and kitchens looking clean for longer.

The range includes a choice of colours such as white, clear and grey to match different fittings and finishes. You’ll also find fast-curing options for quicker turnaround on site, along with trusted anti-fungal formulas designed for long-term protection in damp environments. Available from well-known brands like Soudal, Mapei and Bostik.
