Bathroom Sealant & Tile Grout

The right bathroom sealant and tile grout reduces the risk of water getting in places where it can cause damage and cause damp. Our range includes the tile grout, bathroom silicone sealants and bathroom sealant tools - including sealant guns - you need to get the best results. Looking for other trade supplies? Browse our full range of plumbing parts, including tap replacement parts, flow restrictors, bath resurfacing kits and more.

You can find a wide range of bathroom sealant depending on the job you need it for. We have white silicone sealant as well as a variety of colours to complement your bathroom. You can also prevent those ugly mould growth spots with anti-mould sealants for baths, showers and bathroom sinks.

Tiles alone will not keep out water and that's why they require grout in between them. Alongside plumbing sealant, find tile grout in an array of colours to help you create a unique and striking finish. Shop a range of tile adhesives to help fix your tiles to walls and floors.

BAL Micromax Grout-Effect Sealant

Review From Trustpilot

25th May 2026

Used this on tiled floor in bathroom, the floor has loose floor sheets. Tried several products for grouting without success all breaking up and looking terrible. This is easy to apply and looks like traditional grout.
