Alex..your shower of 1300mm won't give you enough room to walk out if it's a walk in shower...the screen really need to be around 1100mm so it doesn't splash everywhere. Opening the external door outwards is okie if you've got some shelter from the elements..our entry door open out and is under a carport/deck. As per oklouise drawings with 2100mm 600mm washer dryer 900mm shower leaves 600mm for WC which leaves you 100mm either side of the WC. It's doable though your shower door will need to swing out thus not sure if you can fit the vanity across from the shower being only 1800mm wide. unless your internal access is a sliding door.. then you can fit it where the washer dryer is. you'd still need an external access opening outwards as doors are 800-900mm and if you open in you'd bump into your shower door opening out..

if you decide to have a wall hung toilet or towel rails on the toilet wall the cavity slider wall will need to be reinforced to support the weight and a wall hung toiler with inwall cistern will mean that the cavity slider would have to slide towards the vanity..Either hinged or cavity slider doors will be good in this situation although the hinged door has the useful option for hooks for clothes or an extra towel rail...btw consider moving the master bedroom entry door for a more generous entry into the bedroom

Thanks once again oklouise for your comments. I have already been told by the draughtsman that I cannot put in skylights. No idea if this is true but he seemed quite sure and it was he who 'designed' the layout of said ensuite with what I consider a too small window because of ease of plumbing and drainage. He says that can be changed...............Supposedly only put like that to get the oversize plan in fir consent. This department is only interested in the outside view and the effect on the neighbours, which I actually dont have any. The positioning of the ensuite and WiR has changed too from the first plan as I had to come 'out' of my bedroom into a corridor past the WiR door and then into the ensuite. Technically they were both in my bedroom as had not entered the hallway but did not seem like it. So the wall you have now suggested for the door is a small lobby to the bedroom and I had planned to put furniture on it and a full length mirror. I will now look again at the whole space with three zones to see what can be done. I used the word solar tube as I thought that was the generic name for the 'tube' installed which reflected light into a room. Do they cause draughts? Have had no experience of them but will probably want to install one in my scullery (or Butler's kitchen) but am going to work in it a few months before deciding that. I am really quite a novice about function of installations and of building code.

Hi Deonne If your bathroom requires the two doors, my suggestion is NOT to have a bath. Keep it very clean and neat Across the recess have either a walk-in shower with a 600mm opening OR a glass panel and door. You may consider a seat in the shower ( example on our website ) A recess ( niche ) for shower 300mm high max length Wall hung, all drawer vanity. In-wall cistern toilet suite. Mixer diverter, overhead and handheld shower. Quality tapware, with min 10-year warranty Porcelain floor tiles min 300 x 300. Tile to ceiling, ( unless home has high ceiling, if high, tile to an architrave height ) min tile size 600 x 300, Ceramic to rein in cost
