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. It's not as long-lasting as others on this list. But It's affordable, easy to apply, and includes a screw-on applicator nozzle so you don't need a gun for application. It's also available in two different colour options to suit a variety of bathroom deigns. While all good shower sealants boast mould resistance, this sealant includes UniBond’s “triple protection” formula that repels, kills and prevents mould from forming along the side of the bath or shower. Flexible and durable, it’s also easy to apply and touch-dry in only 20 minutes. While it’s somewhat dependent on the level of use your bathroom gets and how easy it is to ventilate, you shouldn’t need to replace sealant more frequently than every few years. However, a poor initial application will almost certainly lead to it needing to be replaced after only a year or so, maybe even less. What other equipment is required to use shower sealant? The Forever Clear’s patented Mould Shield is this sealant's main highlight, which actively prevents the growth of bacteria, mould and mildew.

Not only is the Everflex sealant a favourite among plumbers and DIY enthusiasts, but it also wins big points from us for coming in a great range of colours. 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.

While it’s crucial to use a good-quality shower sealant, there’s no need to break the bank doing so. This sealant from the No Nonsense range is perfect for anyone watching their pennies, or with a lot of sealing to do. There's a lot to consider when selecting the best sealants for your bathroom. Thankfully, the Homebuilding & Renovating team is getting hands-on experience with the products in this buying guide to help you feel confident in choosing the right product for you. Like many sealants on this list, it has anti-mould and mildew properties, but what made it stand out to us was its versatility. Any spare sealant left over from the shower can be used on a range of surfaces around the house, with the product stated as also being suitable for metal, vinyl, laminate, stone, ceramic, stainless steel, granite, wood and glass. So if you always have obb jobs on the go around the house, it will pay to keep some of this handy. Even the best sealant won’t last forever – bathrooms are always going to be fairly humid, and this creates the perfect environment for mould and mildew. To keep your sealant looking new for as long as possible, make sure you keep your bathroom well ventilated and clean any excess water, shampoo and soap from the edge of your shower or bath. Our team is passionate about DIY and home improvement (which probably won’t be a surprise) so we already have detailed knowledge about the brands that make these products.

What is silicone sealant?

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. Silicone sealants are the preferred choice for bathrooms, as traditional caulk, while popular, isn't entirely waterproof. But where do you start when it comes to selecting the right one? This Dowsil sealant is favoured among plumbers, as it resists mould, combats bacteria including MRSA and E. Coli, and dries within an hour. The 785 Sanitary Sealant is a leading product which is particularly popular among plumbers. It utilises a fungicide formula that resists mould to keep your bathroom looking and smelling fresh, and it protects against bacteria growth, MRSA, E. Coli and salmonella. Like most other sealants, it’s mould- and mildew-resistant, but it also contains a fungicide that will resist salmonella, E.coli and MRSA. Helpfully, it also comes in a couple of other colours – clear and grey – making it perfect for adding a really professional finish to any bathroom. It can be touch dry within 15 minutes of application thanks to its high-quality drying formula, plus it includes an anti-bacterial additive which helps to combat against new germs.It's also effective in high humidity areas.
