Silicone Sealants for Bathrooms, Kitchens, Tiles & Wet Areas
Create a cleaner, more professional finish with the right silicone sealant for your project.
Silicone is used around showers, baths, basins, vanities, kitchen splashbacks, benchtops and tiled corners where flexibility and water resistance are required. Unlike grout, silicone is designed to accommodate small amounts of movement, helping reduce cracking around changes of direction and adjoining surfaces.
At Joshua Tiles, you can shop silicone sealants for residential renovations, new builds and commercial tiling projects. Choose from popular colours designed to coordinate with tile grout, porcelain tiles, ceramic tiles and modern bathroom finishes.

Choose the Right Silicone for Your Project
The best silicone depends on where it will be used, the surfaces being sealed and the product specifications.
Bathroom and Shower Silicone
Bathrooms and showers require a sanitary silicone suitable for wet areas. It is commonly used around:
- - Shower screens
- - Internal tiled corners
- - Baths
- - Basins
- - Vanities
- - Toilets
- - Floor and wall junctions
Select a product specifically recommended for the intended wet-area application and follow the manufacturer’s preparation and curing instructions.
Kitchen Silicone
Kitchen silicone is commonly used around:
- - Splashbacks
- - Benchtops
- - Sinks
- - Wall junctions
- - Cabinet edges
Choose a sealant suitable for the surfaces involved and for areas exposed to moisture and regular cleaning.
Tile and Grout Colour-Matched Silicone
Colour-matched silicone creates a more consistent finish where tiled surfaces meet. Popular choices include:
- - White
- - Off-white
- - Light grey
- - Mid grey
- - Dark grey
- - Charcoal
- - Black
- - Beige
- - Sand
- - Ivory
- - Warm grey
For a subtle finish, choose a silicone colour close to the grout. For a stronger design detail, use a contrasting colour. Screen colours can vary, so a physical colour sample is recommended whenever possible.
Outdoor Silicone
Outdoor joints may be exposed to rain, sunlight and temperature changes. Always choose a product specifically approved for exterior use and compatible with the surfaces being sealed.
Natural Stone Silicone
Some sealants may stain or discolour natural stone. For marble, travertine and other porous stone, select a product specifically identified as suitable for natural stone.
Do not assume that a general-purpose silicone is appropriate.
Silicone or Grout: Which One Should You Use?
Grout and silicone perform different jobs. Grout is generally used between tiles across the main tiled surface. Silicone is normally used where flexibility is required, including:
- - Internal corners
- - Wall-to-floor junctions
- - Around baths and shower bases
- - Around shower screens
- - Around basins and benchtops
- - Changes between different materials
- - Selected movement joints
Using grout in areas that require movement accommodation may lead to cracking. Always follow the product manufacturer’s instructions and the installer’s recommendations.
How to Choose a Silicone Colour？
Match the Grout
Choosing a similar silicone and grout colour gives the tiled area a clean, continuous appearance. This is popular in modern bathrooms and large-format tile installations.
Match the Tile
Matching the silicone to the tile can make perimeter joints less noticeable, particularly with stone-look or concrete-look tiles.
Use White for a Clean Finish
White silicone is commonly used around white baths, basins, shower trays and sanitary fixtures. However, it may create a stronger contrast against darker grout or tiles.
Use Darker Colours for Practicality
Grey, charcoal and black silicone may coordinate better with darker tiles and can make everyday marks less noticeable than bright white.

FAQ
Q1. What is silicone sealant used for?
Silicone sealant is used to seal joints and gaps where flexibility and moisture resistance are required. In tiled areas, it is commonly applied around showers, baths, basins, benchtops, internal corners and wall-to-floor junctions.
Q2. Is silicone waterproof?
Many silicone sealants are designed to create a water-resistant or waterproof seal once fully cured. Suitability varies between products, so always check whether the specific sealant is approved for showers, wet areas, exterior use or continuous water exposure.
Q3. What is the best silicone for a shower?
Choose a sanitary silicone specifically recommended for bathrooms, showers and wet areas. Check that it is compatible with the tile, shower screen, bath, shower base or other adjoining surfaces.
Q4. Can I use grout instead of silicone?
Grout and silicone are not interchangeable. Grout is rigid, while silicone remains flexible. Silicone is generally used in corners, perimeter joints and areas where movement may occur.
Q5. Should silicone match the tile?
Matching silicone to the tile can help joints appear less noticeable. This is often effective with large-format, stone-look and concrete-look tiles.
Q6. What colour silicone should I choose?
Choose a colour close to the grout for a seamless look, close to the tile for a more discreet joint, or a contrasting colour for stronger definition. Physical colour samples are more reliable than screen images.
Q7. Can silicone be used around a bathtub?
Yes, provided the product is suitable for bathrooms and compatible with the bath material and surrounding surfaces. Follow the preparation and curing instructions carefully.
Q8. Can silicone be used outdoors?
Only use silicone outdoors when the product is specifically recommended for exterior applications. Outdoor sealants may need resistance to weathering, UV exposure and temperature changes.
Q9. Why does bathroom silicone turn black?
Black staining is often associated with mould growth caused by persistent moisture, poor ventilation, soap residue or ageing sealant. Cleaning may help in mild cases, but badly affected silicone may need replacement.
Q10. How long before I can use the shower after applying silicone?
Wait until the silicone has fully cured according to the product instructions. Do not rely only on the surface feeling dry, as the material underneath may still be curing.
Q11. Why is my silicone peeling away?
Peeling may be caused by moisture, dirt, soap residue, poor surface preparation, incompatible materials or movement beyond the sealant’s capability. The underlying cause should be corrected before resealing.
