I am currently trying to make similar decisions about bathroom wall tiles heights and where to extend to. I have a couple of littlies and hate the mess on the painted surfaces in both this and our previous bathroom. Splashes on the wall near the hand towel and behind toilet. What level of tiling does the bathroom your sons currently use have? I quite like the idea of tiling behind the towel rails or hooks but it probably isn't essential if there is good ventilation (and heating in cooler weather).

Having helped my mother in law with her shower room (she has MS) and helping a friend who just broke her leg ... the bigger shower is a great decision, but I wouldn't build in a bench. down the track if she needs to sit to shower, she will probably need a shower chair with arms to lower herself up and down and to be able to move it around if someone is helping her shower. then anyone else showering can just take it out and enjoy the bigger shower!

While brass door hinges are commonplace at Bunnings, I think that Babajate is looking for specialised brass hinges for a glass shower door, possibly a frameless glass door? Normal brass hinges for timber doors and door frames aren't going to work. I don't know if brass glass door hinges are actually available in Australia, so as an alternative have you considered matt black hinges, which won't clash like polished chrome hinges?Best of luck on your hunt, Dr Retro of Dr Retro House Calls

I’d have the bolt locks powder coated. It’s not an onerous process once you find some to do them. The window supplier may have an industry contact. Or if you’re handy you can spray paint them yourself. I’m not a fan of black tapware but you don’t need to worry about it matching the window/door hardware a different metal will be fine if that’s the way you choose to go.
