Like many sealants on this list, it has anti-mould and mildew properties, but what made it stand out to us was its versatility.
This product from Dowsil, formerly known as Dow Corning, has been around for many years, and it remains of the most popular sealants on the market. In addition to the standard white and clear, it comes in grey, ivory and sandstone, meaning you can match it perfectly to your tiles and general bathroom colour scheme. For many silicone sealants, this can take up to 24-hours, even several days when applying a heavier coat.The attached sealant gun makes it easy to use, and an integrated resealable cap is handy so you can do little bits at a time without worrying about the product drying out. The formula includes a fungicide that provides excellent protection against mould and mildew, making it ideal for showers and baths that see heavy use. While not as durable as others, it's affordable and easy to apply without a gun, thanks to a screw-on nozzle. Its high adhesion formula helps to create a durable result that will stay consistent, and once applied, it forms a permanently flexible and waterproof seal, which reduces the chances of the seal breaking.

Given the wet and humid conditions prevalent in bath and shower rooms, the application of a suitable bathroom sealant – particularly around sinks, baths, and shower trays – is essential. A close second-place, Everbuild's Everflex 500 anti-mould sealant is a great model, and efficient across several fronts. A skin will form within 10 minutes after application, then you'll need to wait around an hour for it to be tack free, and roughly 24 hours for it to be completely dry. We’ve put together a list of the top-notch shower sealants, including those beloved by plumbers, the best anti-mould sealants and a great quick-dry option, ideal for those who want to get their bathroom looking refreshed in record time.
It's mould-resistant, suitable for all surfaces, and offers a lifetime guarantee against cracking and shrinking. However, a poor initial application will almost certainly lead to it needing to be replaced after only a year or so, maybe even less. It’s easy to get the hang of relatively quickly and mistakes can be rectified if cleaned up quickly.
A plentiful supply of rags is also a must, as mistakes should be corrected as quickly as possible before the sealant hardens. Silicone sealant is an adhesive sealant that is highly versatile, extremely weather resistant, and long-lasting, making it the most widely used sealant in the world. Sealing a bath or shower is never going to be a super speedy task, but this sealant from UniBond can get your shower back up and running only an hour after applying. Drying within 15 minutes, it contains an anti-bacterial additive and is effective even in high humidity areas.Setting in a speedy 30 minutes, this sealant provides durable waterproof protection – as well as being crack-, shrinkage- and discolouration-proof.
