because the water could seep through the joints between the new tiles and sit between the two layers and affect the seal and also raise the height of the floor and affect the slope to the waste outlets..but, why do you want to retile if you're not using the bathroom??...for immediate resale consider bathroom wall to wall bathroom carpet, new wall paint, new vanity, taps and light fittings which should also be cheaper than tiling over the top and, if it's not allowed by the body corporate, it will be a risk to future sales as it should not satisfy a proper building inspection

Nup, a good tiling job requires a good substrate. The best tiler in the world can't make a bad substrate look clean and good.

When it comes to kitchen design for a ranch house renovation, you may want to consider the following factors: Space and layout: Ranch houses typically have an open floor plan, so you can create a kitchen that flows seamlessly with the surrounding living areas. Consider the space available and the placement of windows and doors when deciding on the layout of your kitchen. Style: Ranch houses often have a mid-century modern or rustic aesthetic, so incorporate these design elements into your kitchen renovation. For example, you could use warm wood tones, clean lines, and vintage-inspired fixtures to create a timeless and inviting space. Storage: Adequate storage is essential in any kitchen, but it's especially crucial in a ranch house where storage space may be limited. Consider incorporating cabinets, shelves, and other storage solutions that maximize the available space without overwhelming the room. Lighting: Good lighting is essential in any kitchen, but it's particularly important in a ranch house where natural light may be limited. Consider incorporating a mix of ambient, task, and accent lighting to create a warm and welcoming atmosphere. Ultimately, the best kitchen design option for your ranch house renovation will depend on your specific needs and preferences. Consider working with a professional designer or architect to help create a space that meets your functional and aesthetic goals. You can contact house tiling services Sydney.

Yes I have by Precious Tiling. For my home, we first did the concrete flooring then laid the vinyl tiles. For a quality job, the substrate must be clean, flat, and very smooth. To fit tile around pipes or obstacles, cut a pattern from cardboard and then use a contour gauge or compass to transfer the pattern onto a tile.
