Embarking on a bathroom renovation project in New Zealand? Tiling your shower is a rewarding task that can significantly enhance your space’s aesthetic appeal and functionality. This comprehensive guide walks you through the steps to tile a shower in NZ like a pro.
Before you dive in, remember that tiling a shower involves precision and patience. It’s crucial to have the right tools, quality materials, and a solid understanding of the process. This guide assumes you have basic DIY skills and are using ceramic or porcelain tiles, which are popular choices for NZ showers due to their durability and water resistance.
Preparation and Planning
ansible
Before you start, ensure your shower area is clean, dry, and free from any old tiles or debris. If you’re working with new construction or previously untiled walls, you’ll need to apply a cement-based backing board. In NZ, we often use Platon or similar fibre cement boards due to their durability and ease of installation.
Gather Your Tools and Materials
- Trowel (notched and straight-edged)
- Tile cutter or nippers
- Level
- Tape measure
- Thinset mortar (waterproof cement-based adhesive)
- Waterproof membrane (such as tanking membrane orgaflex)
- Tile spacers
- Tile nippers or wet saw
Design and Layout
Lay out your tiles on the floor to plan your design and determine the best starting point. Typically, it’s best to start from the centre of the wall and work outwards to minimise cuts. Consider using bullnose or pencil tiles for the bottom row to create a clean, finished look. In NZ, we often see showers tiled with a subway or pattern layout, but the possibilities are endless.
Pro tip: Ensure tiles are laid against the wall horizontally and not vertically to prevent water from being channelled upwards behind the tiles.
Waterproofing and Tiling
Applying a waterproof membrane is a critical step in tiling a shower in NZ to prevent water damage. New Zealand’s naturally damp conditions and frequent rainfall make this a crucial aspect of any shower installation.
Apply the Waterproof Membrane
Start from the bottom of the shower and apply the waterproof membrane (like tanking membrane orgaflex) horizontally, overlapping each strip by at least 100mm. Ensure the membrane extends up the walls and around any fixtures. Follow the manufacturer’s instructions for specific application guidelines.
While some membranes can be used as a tile adhesive, it’s recommended to apply a separate layer of thinset mortar for added protection and better adhesion.
Mix and Apply Thinset Mortar
Mix thinset mortar according to the manufacturer’s instructions. Apply the mortar to the wall using a straight-edged trowel, then use a notched trowel to create grooves for better tile adhesion. Work in small sections at a time to avoid the mortar drying out.
Lay the Tiles
Pick up your first tile and apply some thinset mortar to the back using the notched edge of your trowel. Press the tile firmly into place, using a level to ensure it’s properly aligned. Use tile spacers to maintain even grout lines as you work outwards.
For bullnose or pencil tiles, you may need to use tile nippers or a wet saw to create the perfect fit. Be sure to wear safety glasses and follow the tool manufacturer’s guidelines for safe and effective use.
Grouting and Sealing
Allow the thinset mortar to cure for the recommended time – usually 24-48 hours – before applying grout. Prepare your grout according to the manufacturer’s instructions, ensuring it’s mixed well and free of clumps.
Apply Grout
Spread the grout over the tiles using a rubber float, working it into the grooves with a diagonal motion. Let it sit for the recommended time (usually 10-15 minutes), then clean the tiles with a damp sponge, being careful not to remove the grout.
Seal the Tiles
Once the grout has cured (typically after 72 hours), apply a sealant to protect your newly tiled shower from moisture and stains. In NZ, we often use silicone-based sealants for showers, as they create a flexible, waterproof barrier.
Pro tip: Apply the sealant using a caulking gun, creating a smooth, even bead over the grout lines and anywhere the tile meets the shower base or walls.
Congratulations on successfully tiling your shower in NZ! Enjoy the sense of accomplishment that comes with completing a project like this. Regular cleaning and maintenance will help keep your new tiles looking stunning for years to come. Happy tiling!
