Rebecca Pountney Design - Richmond ensuiteIndustrial Bathroom, Melbourne

Here are large-format tiles in a stacked layout.

4. Location: Melbourne, VictoriaWhy we love it: Achingly simple lines, moody greys and plenty of breathing space combine to create a calm, meditative bathroom setting in this renovated Richmond terrace. Plus we love how the soft light filtering in through the window above adds a warm glow.

If mid-grey isn’t your thing, go for darker charcoals for a tinge of glamour and sophistication. The industrial-style light (with a yellow rather than white globe) and timber benchtop add welcome warmth and moodiness to this space.Browse more grey bathrooms

Porcelain is, however, weightier than other ceramic tiles, which can lead to issues if the walls are not particularly strong. Contact a professional to determine the strength of your walls before installation, or use tile backer board that will support the weight of the tiles.

Never assumeYou know the saying. When writing your specifications or drawing your plans, never assume someone else will know what you want unless you explicitly state it. Include every tiny detail, no matter how pedantic it may seem. As well as avoiding mistakes, it also prevents any disputes over what is and isn’t included in the quote. This bathroom just wouldn’t have looked the same if white grout had been used, for instance. You might think it would be absurd to even consider using white grout in this case, but if you haven’t asked for dark grey, you can’t expect it and you can’t assume you will be asked what colour you want. White is standard and a tiler may use it if nothing has been specified.

Porcelain/vitrified tiles Porcelain tiles are the easiest to clean. Sweep every couple of days with a soft broom or brush, and vacuum once a week with the brush attachment to remove most dust. Once a month, wash with a solution of water and dishwashing detergent. Use a soft mop and leave to air dry. Mop with warm water and a little vinegar for a great finish.Vitrified tiles are ceramic tiles. The clay is mixed quantities of silica, quartz and feldspar, and when they are fired these elements melt and form a glass-like texture throughout the tile. They are non-porous and stronger than regular ceramic tiles. They have a glossy finish and you can apply the same cleaning method as with porcelain tiles. WHAT TO AVOID: Clean up spills as they happen. Don’t leave them to dry on the surface of the tile as they may cause a stain.
