⚡ TL;DR — Quick Summary
- Preparation decides the result. A clean, dry, level and structurally sound surface matters more than how neatly you lay the first tile.
- Buy 10% extra tiles to cover cuts and breakages. This is the single most common thing DIYers get caught out on.
- Work in small sections. Roughly one square metre of adhesive at a time, trowel held at 45 degrees, so nothing dries before the tiles go on.
- Check as you go with a spirit level and spacers rather than at the end, when fixing it means lifting tiles.
- Respect the drying times. About 24 hours before grouting, and 24 to 48 hours of grout curing before sealing.
- Waterproof wet areas first, mind slip resistance on floors, and ask before you buy if anything is unclear. Free advice is cheaper than a redo.
Tiling your own bathroom is one of those jobs that looks straightforward until you are standing in the room with a trowel in your hand, wondering whether you are about to waste a weekend and a few thousand dollars. That hesitation is normal, and it is a good sign. It means you want to get it right.
Tiling your bathroom might seem like a big ask, but with the right preparation and technique, it is an exciting DIY project that can transform your space.

Prepare Your Bathroom Surface
A clean, level surface is essential for proper tile adhesion. Work through these in order and do not move on until each one is genuinely done.
Phase 1: Strip it back and repair
Phase 2: Check before you commit

Step-by-Step Tiling Process
Seven steps, in order. Nothing here is complicated on its own. The skill is simply doing each one properly before moving to the next.
1. Plan Your Layout
Start by determining the focal point of your bathroom and plan your tile layout from there. This helps avoid awkward cuts and creates a balanced appearance.
Mark reference lines on your walls or floor using a spirit level to ensure your tiles will be straight. For bathroom walls, start from the bottom row and work upward.
2. Apply Adhesive
Mix your adhesive according to the manufacturer’s instructions. Using your notched trowel:
- Apply adhesive to a small area, about 1 square metre, at a time
- Hold the trowel at a 45 degree angle to create ridges in the adhesive
- Work in manageable sections so the adhesive does not dry before you place tiles
3. Set Your Tiles
Starting from your reference lines:
- Press each tile firmly into the adhesive with a slight twisting motion
- Insert tile spacers at each corner to maintain even gaps
- Use your spirit level frequently to check that the tiles remain straight
- Wipe away any excess adhesive immediately with a damp cloth
4. Cut Tiles as Needed
For edges and around fixtures:
- Measure the space where a cut tile is needed
- Mark your cutting line on the tile
- Use a tile cutter for straight cuts or a wet saw for more complex cuts
- Smooth any rough edges with a tile file
5. Allow Proper Drying Time
Let the adhesive dry completely before grouting. This typically takes 24 hours, but check your adhesive packaging for specific instructions.
6. Apply Grout
Once the adhesive is dry:
- Remove all tile spacers
- Mix grout according to package instructions
- Using your rubber float, press grout into the joints at a 45 degree angle
- Work in small sections, wiping excess grout from tile surfaces with a damp sponge before it dries
- Allow grout to set slightly before final cleaning with a clean, damp cloth
7. Seal and Finish
After the grout has cured, usually 24 to 48 hours:
- Apply grout sealer to protect against moisture and staining
- Reinstall fixtures and fittings
- Apply silicone sealant around edges, fixtures, and where walls meet floors
Warning: do not spread more adhesive than you can tile before it dries, and do not grout until the adhesive has fully dried. Both shortcuts feel like they are saving time on the day, and both are difficult to undo once the tiles are down.
The numbers that catch DIY tilers out
Ordering exactly what the room measures
Cuts and breakages are part of every tiling job. Running short mid project can mean a different batch, or a wait.
Order 10% extraSpreading too much adhesive at once
Adhesive that skins over before the tile goes on will not bond properly, and you will not see the problem until much later.
1 square metre at a time Trowel at 45 degreesGetting impatient with drying and curing
Grouting over adhesive that has not dried, or sealing grout that has not cured, undoes the work you have already done.
24 hours before grouting 24 to 48 hours to cureThese are typical timeframes. Always check the specific instructions on your adhesive and grout packaging, as products and conditions vary.
Checking your work as you go, and what each result means
Level reads true and spacer gaps are even
You are on track. Keep checking with the spirit level frequently rather than only at the end of a row.
A tile sits proud, low, or off the reference line
Fix it now, while the adhesive is still workable. Once it dries, correcting it means lifting the tile.
Gaps look slightly uneven near a wall or fixture
This is often the wall or floor rather than your tiling. It is why the surface check in the preparation stage matters so much.
Wipe away excess adhesive immediately with a damp cloth as you go. Cleaning up at the end is far harder than cleaning up along the way.

Pro Tips from Our Experts
These four details separate a job that looks good on day one from a job that is still sound in five years.
Waterproofing
For wet areas like shower recesses, apply a waterproofing membrane before tiling.
Expansion joints
Leave a small gap between tiles and walls to allow for natural expansion.
Tile selection
Consider slip resistance for floor tiles and water resistance for wall tiles.
Underfloor heating
If installing underfloor heating, ensure your tiles are compatible.
Important: waterproofing goes in before the tiles, not after. If your project includes a shower recess or any other wet area, this is the one step you cannot come back and add later.
