Buying the best bathroom sealant is an important step to help you apply the finishing touches to your bathroom and to keep it looking its best.
As bath and shower rooms are subject to wet and humid conditions, you need to apply a suitable sealant around your sanitaryware, including sinks, baths and shower trays in order to prevent water damage and the growth of mould.
It is best to use silicone sealant in your bathroom. While caulk is a popular method of sealing for walls it is not the best option for bathrooms as it is not completely waterproof.
These are the best bathroom sealants for the job.
Which is the Best Bathroom Sealant?
1. UniBond Anti-Mould Sealant
Easy to use with long-lasting protection
Size: 300ml | Colours: White or Ivory | Waterproof: Yes
UniBond’s silicone sealant has been developed with an anti-mould formula that is designed for use in warm in humid environments. This UniBond sealant forms a permanently flexible (which reduces the chances of the seal breaking) and waterproof seal that is touch dry in just 20 minutes.
The attached sealant gun makes it easy to use, and an integrated resealable cap makes it an ideal for doing little bits at a time without worrying about the product drying out. It provides a long-lasting finish and is available in two different colour options.
2. Everflex 500 Bath & Sanitary Silicone
This sealant offers long-lasting protection against mould growth
Sizes: 295ml, 310ml | Colours:: White, Ivory, Translucent, Sandstone | Waterproof: Yes
The Everflex 500 sealant from Everbuild is another anti-mould sealant that is supremely efficient across all areas of bathroom sealing.
This is a permanently flexible sealant that incorporates a powerful fungicide into the formula, providing long-lasting protection against mould growth.
It also dries quickly: wait around an hour for it to be tack free, and roughly 24 hours for it to be completely dry.
Even better, this sealant will not discolour on ageing, even in humid or damp conditions.
3. Gorilla Glue Mould Resistant Sealant
An under-rated product that dries extremely quickly
Size: 80ml | Colours: Clear | Waterproof: Yes
Once applied, the versatile Gorilla Glue Mould Resistant Sealant is water-ready within 30 minutes.
Mould resistant, this sealant can be used on all surfaces, and comes with a lifetime guarantee that it will not lead to cracks or shrinks.
The cherry on top is that it comes with a reusable nozzle making it very easy to apply.
4. Forever Clear Anti-Mould Bathroom Sealant
The high-quality drying formula delivers touch-dry sealant within 15 minutes
Sizes: 80mm squeeze tube, or 295ml tube | Colours: White, Ivory, Grey or Clear | Waterproof: Yes

It can be touch dry within 15 minutes of application thanks to its high-quality drying formula. It also includes an anti-bacterial additive which helps to combat against new germs.
This may not be among the most well-known sealants, but it is effective in high humidity areas and more than justifies its place in this list.
5. Dowsil 785 Sanitary Sealant
This will keep your bathroom looking and smelling fresh
Size: 310ml | Colour: White | Waterproof: Yes
