Good advice BC. My comment is a little off topic but related to mixers generally. I'm doing all I can to utilise sustainable options for a lot of things in my new house and was surprised to read on a govt power info page that mixer taps use more power than just about anything else! When I thought about it I realise I turn the taps on and take what I need, before it heats up if it's in that position, rather than ensure it's always on cold to start. The stop start of the HWS gets a workout here I know and I don't think we're the only household guilty of that. The website didn't recommend them. I've now changed my mind about a mixers for the new house and going back to hot and cold taps. Who knew :-0

If you use this product it will take a long time to fill tub!! Yes looks nice as that was for me too but change. My home I built was total solar and worked great!!!! They installed ones like yours and takes for ever to fill a tub!! Looks great but no satisfaction to what you want!! Ken

you'll need a plumber to check the existing pipes but you may be able to access inside the wall from an adjoining room (easier and cheaper to replace plasterboard than tiles) and be able to add a new shower with a reachable shower rose as well as a handheld but i hope you have a few spare tiles or can steal some from a less obvious place ...best of luck with the plumber but research suitable new showers with handheld and adding the plumber's time and repairs expect at least $2-$3 thousand but well worth it for a more comfortable bathroom

Anna - your first photo of the terrazzo tile running up the bathroom wall is really striking, but I think it is the soaring ceiling with the natural light flooding in that makes it so appealing rather than the terrazzo tiles. All of the bathrooms are a similar size, so one way to avoid the stress of all those selections (in a short time) is to find the right tiles and follow it through consistently for all three bathrooms. I agree with you that the dramatic all charcoal tile may be a bit overpowering in a small space, unless you want to go for that nightclub/bachelor pad feel for your kids bathroom. Your kids may think it is cool now, but what about in five years time? You also need to think about how long you are going to live in the house, and how long until you renovate your bathrooms. I think that the vertical subway tile will date quickly, and in 2028 it will look very 2018. The terrazzo tile is classic, timeless, hardwearing and beautiful so I would probably be considering the terrazzo as a floor tile in all three bathrooms, matched with a large format white or soft grey wall tile that complements your terrazzo colours. This solution will give you practicality, longevity and make the spaces feel bigger. Go for understated and elegant when it comes to tile selections in bathrooms if you need them to look good for a long time. But if you are in a financial position to renovate your bathrooms in ten years time go with what is fashionable and on-trend now. Best of luck (and don't stress) Dr Retro of Dr Retro House Calls
