Our IXL Tastic is still going after 10 years of daily use. The heat isn't super powerful but we have ducted heating so its neither here nor there. The fan however is quite good. Not saying the Tastic is the best but its still going with the original lamps......and it was cheap to buy and install.

I love no.1. The black wall and white floor draws my eye and it skims past all the soft white fittings. It creates a sense of space and flow. It has continuity. In no.2 my eye hits the dark floor then gets distracted by the white loo and two coloured vanity. That's where it stops. No. 3 is my least favourite. In no.3, the white wall is harsh and draws attention from the rest of the bathroom. It gives me a sense of harsh disjointedness.

Both our bathrooms have the same setup you have shown. Our electrician said the Bunnings heat/light/fan combos are pretty useless and he sourced a more powerful version for us. We kept the round fans as we weren't doing full renos and didn't want to spend more on plastering. Yes, the look is messy but having both is an effective way to manage the steam. Our electrician said to turn the heat and fan on at the start of the shower and keep it running for a few minutes after. We live in a similar climate to you and this works well - although not in the 40 degree summer haha!!

One important aspect to consider during your bathroom renovation is ventilation. Make sure you have a good exhaust fan to prevent moisture buildup and mold growth. Also, think about the layout of your bathroom. If possible, try to create separate areas for the shower and toilet to increase privacy. And don't forget about the little details! Upgrade your hardware, such as faucets and showerheads, for a more polished look. Best of luck with your project! Remember to always consult professionals and follow local building codes and regulations when undertaking any renovation project. Share your own experiences and ask more questions to keep the discussion going. Happy renovating, everyone!
