Epoxy grout gains ground over cement grout in bathrooms and kitchens in 2026

In bathroom and kitchen construction and refurbishment projects, cement grout is steadily being replaced by epoxy grout. In 2026, architects, engineers and installers are increasingly recommending it for wet areas because it combines strength, waterproofing, colour stability and a more consistent finish across the joints, meeting growing demand for durable, low-maintenance solutions.

What is epoxy grout and why is it popular in 2026?

Epoxy grout is made from epoxy resin, hardener and specialised mineral fillers, creating a dense, highly waterproof material. This differs from cement grout, which is naturally porous and more vulnerable to water ingress. Under continual exposure to water, steam and cleaning products, epoxy performs more effectively, helping to prevent detachment and reducing staining of the tile finish over the years.

Colour stability is another benefit receiving attention in 2026. Traditional cement grout can darken, crumble or become stained in places such as shower enclosures and around cookers. When correctly applied, epoxy grout retains its original shade for longer, withstands regular washing when the manufacturer's guidance is followed, and helps create the impression of more continuous surfaces in contemporary bathroom and kitchen schemes.

Is epoxy grout more resistant to mould and moisture?

Protection against mould is one of the leading reasons for replacing cement grout in wet locations, including shower enclosures and bathroom skirting areas. Cement absorbs water and grease, producing conditions that encourage fungi and bacteria. Epoxy, by contrast, creates an almost non-porous layer where moisture does not build up as easily, helping to limit darkening in the joints.

In kitchens, joints near the sink and cooker are likely to remain visibly cleaner. Some manufacturers also add fungicidal additives to the formula to reinforce this characteristic. Despite this protection, regular cleaning with suitable products remains essential to maintain performance, appearance and hygiene over time.

Main advantages of epoxy grout over cement grout

When bathrooms and kitchens finished with epoxy grout are compared with those using cement grout, differences can be seen in joint durability, ease of cleaning and the finished appearance of the tiled surfaces. With large-format porcelain tiles and rectified tiles, choosing the right grout colour can produce an almost monolithic effect, which is widely sought after in contemporary, minimalist interiors.

Among the benefits most valued by those specifying or using epoxy grout are features that directly affect the lifespan of the finish and everyday maintenance:

• High waterproofing: helps to reduce water ingress and moisture staining between tiles.
• Greater chemical resistance: better withstands cleaning products recommended by the manufacturer.
• Reduced mould growth: low water absorption makes fungal growth more difficult.
• Longer-lasting joints: tends to crack and crumble less over the years.
• A more uniform finish: stable colours enhance tiled floors and walls.

How is epoxy grout applied, and what is its effect on cost and appearance?

Applying epoxy grout is more technical and generally requires experienced labour. The product comes in two components, which must be mixed in the correct proportion and used within a limited time. Joints must be clean and dry, the grout is pressed in with a rubber float, and surplus material needs to be removed promptly using a lightly dampened sponge to prevent an unwanted glossy film from forming over the tiles.

In 2026, the price per kilogram of epoxy grout and the labour cost remain higher than for cement grout. However, many projects consider the outlay worthwhile because of its greater durability and the reduction in future repairs. The extensive colour range makes it possible either to conceal joints in large-format tiled floors or to create striking contrasts, coordinating worktops, walls and floors within the same visual language while contributing to a more modern setting that is easier to maintain.
