we also like the look of the back to wall shower grate and have not been able to find cheaper and longer sizes are much more expensive but we have one shower with the grate against the wall and another shower with a shorter shower grate across a doorway and despite preferring the look of the grate along the wall the smaller one at the outside of the shower is more efficient, cheaper and much easier to clean

Hi Hu, In terms of shower placement - not necessarily. It can be where ever you wanted it and common sense will prevail. A consideration with the smart tile grates (dependent on which you use) sometimes they dont allow the water to escape fast enough. They have a tendency to sit low in the cradle and inhibit the water drainage. If the water is sitting around your feet the drainage point would seem to be in the right place. It could be a partially blocked drain and that can be myriad of reasons. There are silicon seals that clip on the door that will stop water (nearly always a problem with frame-less screens) escaping. But please talk to your Builder and get him/her to examine the problem. Ask your Builder to get the plumber back to check it out for you. I hope this is helpful. Cheers Trevor

Go back to the builder first it should be still under warranty and see what he says. It shouldn’t be coming up but depends on how you treat it when cleaning, The rubber is silicon and should be a mould resistant type, but I am surpised it is around grate, Post a picture

Unfortunately a cavity sliding door on the toilet won't work due to structural considerations. It would be a massive task to modify the existing wall to create a cavity. Anyway, I don't like them. Every house I've been in that had a cavity slider it sagged, and they are so hard to adjust when that happens. They are a great idea in theory, but I've not seen one work well in practice. I did consider a barn slider along the toilet side. Not sure what you mean by an 'inbuilt basin', Shirley. If you mean the type that sit over the toilet cistern, I looked at them and rejected because they are awkward to get at and use. In UK, they make units with an integrated basin next to the cistern and some are very stylish. Nothing like that available in Aus, sadly. I also wanted to ensure there was at least a small amount of cabinet space for toilet cleaner and cloth and spare toilet paper and a few personal conveniences. Where are you located, Julia Lesley? We are on the Sunshine Coast and finding it well nigh impossible to get building tradespeople to do anything at present. The renovator I mentioned above is booked up for 5 months!
