You searched for floor tile prices in Kenya to budget for your project. That price, however, typically accounts for only 30-40% of the total job cost.
The long-term success of your bathroom tiling depends on the materials used beneath the tiles, specifically the waterproofing, adhesive, and sealant.
Understanding the Full Cost of Tiling a Bathroom
The total cost of a tiling project is a combination of the tiles themselves and the installation materials and labour.
Focusing only on the per-metre tile price can lead to budget shortfalls and poor results.
Average Tile Prices in Nairobi (Per Square Metre)
Tile prices vary based on type, size, and finish. The following table provides a general market overview for January 2026.
| Tile Type & Size | Average Price Range (KES per m²) |
|---|---|
| Ceramic (30×30 cm) | 850 – 1,100 |
| Ceramic (40×40 cm) | 950 – 1,300 |
| Porcelain (60×60 cm) | 1,400 – 2,200 |
| Vitrified (60×60 cm) | 1,600 – 2,500 |
The Hidden Costs: Labour, Adhesives, and Prep Work
The final project cost is significantly influenced by factors beyond the tiles. Using a cheap tile with substandard installation materials often costs more over time due to repairs. A proper budget must account for:
- Labour costs (fundi charges).
- Cost of tile adhesive and grout.
- Waterproofing materials.
- Screeding material for levelling.
- Silicone sealant for corners and fixtures.
Your Complete Bathroom Tiling Materials Checklist
Assembling all the necessary materials before starting work prevents delays. A professional tiling job requires more than just tiles and cement.
The Tiles: Choosing Between Ceramic and Porcelain
The primary difference between ceramic and porcelain tiles is the water absorption rate.
Porcelain tiles absorb less than 0.5% water, making them denser and more suitable for wet areas like shower floors. Ceramic tiles are more porous but are a cost-effective choice for bathroom walls.
The Bonding Agents: Adhesive, Grout, and Sealant
Contractors often misuse these three distinct products. Each serves a specific function.
- Tile Adhesive: A cementitious or polymer-modified product designed to fix tiles to the substrate. Its only job is to bond.
- Grout: A material specifically for filling the gaps or joints *between* tiles. Grout is not an adhesive.
- Silicone Sealant: A flexible, waterproof sealant for corners and joints where fixtures meet tiles. Silicone sealant accommodates movement where grout would crack.
Waterproofing Compounds and Membranes
Waterproofing is a non-negotiable step for any bathroom in Kenya.
These materials come as a liquid-applied membrane or a cementitious slurry that creates an impermeable barrier beneath the tiles.
Spacers, Trims, and Other Essentials
Small items ensure a professional finish. This list includes tile spacers for uniform grout lines, tile cutters, notched trowels for applying adhesive, and edge trims for clean corners.
Step 1: Preparing the Walls and Floor Correctly
Proper surface preparation is the foundation of a tile job that does not fail. Tiles fixed to an unprepared or uneven surface will eventually crack or delaminate.
Removing Old Tiles and Fixtures Safely
The demolition phase requires care to avoid damaging underlying plumbing or electrical lines. Shut off the main water supply before removing any fixtures like the toilet or sink.
Creating a Level and Stable Surface (Screeding)
The substrate must be perfectly flat, especially for large-format tiles. A floor screed (a sand and cement mixture) is applied to create a smooth, level base for the tile adhesive.
Step 2: Waterproofing the Shower Area and Floor
Water damage is the most common cause of tiling failure. This step prevents moisture from penetrating the structure of the building.
Why Standard Cement is Not Waterproof
A common mistake is assuming that standard sand and cement plaster or screed is waterproof. It is not.
Cement is porous and will absorb water, leading to dampness in adjacent rooms and the eventual failure of the tile adhesive.
Applying a Waterproofing Membrane or Slurry
A modern waterproofing compound should be applied over the cured screed, especially in the shower area and across the entire floor. The compound is typically applied in two coats with a brush or roller, creating a seamless barrier.
Step 3: Laying, Grouting, and Sealing the Tiles
This is the final installation phase. Using the correct products and techniques here ensures a durable and aesthetically pleasing finish.
Choosing the Right Tile Adhesive
You should use a polymer-modified tile adhesive in wet areas. These adhesives contain polymers that improve bond strength and water resistance, preventing tiles from detaching in damp conditions.
Applying Grout to the Tile Joints
Grout is mixed to a paste-like consistency and forced into the joints between tiles using a grout float. After a short drying period, the excess is wiped from the tile surface with a damp sponge.
Sealing Corners and Fixtures with Silicone
Grout should never be used in corners where a wall meets a floor or another wall. These are movement joints.
Grout is rigid and will crack. A flexible, anti-fungal Silicone Sealant is the only correct product for these areas, as well as for sealing around the base of a toilet and the edges of a sink or shower tray.
The Dingli A6015 Silicone Sealant provides a waterproof seal that accommodates this movement.
Expert Take: Tiling is More Than Just the Tile
A successful bathroom tiling project depends on a systematic approach. Budgeting for the correct waterproofing, adhesive, and sealing materials is more important than the price of the tiles themselves.
A job done right with quality materials will last for decades, while a job done cheaply will require expensive repairs.
Frequently Asked Questions
How much does it cost to tile a small bathroom in Kenya?
For a standard 2m x 2m bathroom, the total cost including labour, tiles, and all materials typically ranges from KES 40,000 to KES 70,000, depending on the quality of the tiles and fixtures.
Do I need to waterproof my entire bathroom?
You must waterproof the entire floor and the walls of the shower area up to a height of at least 6 feet. Waterproofing all walls is recommended for maximum protection.
Can I use normal cement to fix tiles?
You should not. Normal sand and cement mixtures do not have the bond strength or water resistance of a proper tile adhesive. Using them will likely lead to tile failure.
What is the best sealant for shower corners?
The best and only correct product for shower corners is a 100% waterproof, anti-fungal silicone sealant. Silicone sealant remains flexible to prevent cracking.
