How Do Contractors Tile a Bathroom Floor?

Most bathroom or toilet renovation involves re-tiling the floor. Broken and cracked tiles are an eyesore to anyone walking in. So what do you do? Most of us would start searching the web (or the yellow pages if you’re old school) for a list of renovation contractors in Malaysia who could do the job. You call them, get a quote, and then shake on it.

However, most homeowners have a vague idea of how floor tiling works and what to expect. It’s always beneficial to go into a situation like this with a little bit of background knowledge.

This is how a common tiling job is done by a professional contractor:

1. Start with a Plan

To get started, your contractor would want to discuss what you want to get done with your bathroom floor. Share all your thoughts and ideas on types of tile materials, layout, design etc, and ask him for his opinion. He should be able to provide advice on how best to match your demands, feasibility, alternatives and others.

2. Prepare the Subfloor

The first thing your contractor does is to properly prepare the subfloor. Otherwise, the tile will crack and come loose very quickly. The subfloor works to provide a flat surface with minimal deflection (bounciness). These deflections can be reduced by adding extra layers underneath with materials such as plywood.

Professional flooring contractors and tilers are able to judge a floor’s deflection by feel alone. Otherwise, there is a standard formula contractors use to measure the level of deflection.

Once that is done, the contractor will find a suitable point to center your layout by either using a tile or a grout line.

3. Clean the Surface

Cleaning is done easily with a sponge. This wets the plywood, giving it a good bond when tiling.


4. Mark Guide Lines

Next, he will trace the outline of the drainage hole in the floor, and measure a spread line off the exterior wall.


5. Mix & Spread Thinset

A thinset will then be mixed until it is the right consistency for spreading.


The thinset will be spread right up to the spread line (but not covering it) with a tool like a notched trowel.


6. Lay the Tiles

Experienced contractors are usually able to lay the tiles down by look and feel.

Otherwise, do not fret as there are tools they can use. Normally (or if they prefer to be extra cautious), they would use ‘spacers’ to ensure the tiles are well joint.


7. Pack in the grout


Grouting is done after the tiles have set.

There are 2 types of grout – sanded and unsanded. Sanded grout is preferred for floors because it shrinks less due to higher sand content, suitable for wider grout joints.

A grout trowel would be used to packed the grout in tightly. Any excess is scraped away as much as possible.

8. Clean Up

When the grouting is all done, the tiles will be cleaned often with a damp sponge. Caulk would be applied in the corners of your bathroom floor.

You should be able to use your bathroom again after 48 hours (ideally). Check with your contractor to be sure.
