In situations like these, it depends what you normally use your laundry sink for. If you don't really need a 'laundry' tub as such, I usually recommend that my clients get a nice, comfortable and good-looking bathroom basin that they feel will suit their needs, and install a kitchen sink mixer, instead of a normal basin tap, so that the tap can be moved if you need to use the basin for larger items. Then add a hand towel ring and nice hand-soap dispenser and you have a dual purpose washing area. I always try to install washing machines and dryers in tower units, but not at the cost of benchspace - so it will really depend on the room layout (which I can't quite determine from your photos). Neat overhead storage is a must. Underbench pull-out clothes baskets and broom cabinets are always good, if you have the room. All the best!

In case it is of help to you - Our concealed laundry dimensions are 2406mm X 700m deep with two bifold doors concealing this span. The bifolds have this mechanism https://www.hettich.com/au_EN/products/folding-and-sliding-door-systems/folding-door-system.html and it is very smooth. The large sink, washer, dryer fit into/under a bench 1875mm long and the extra space is the broom space. The entire length has overhead shelves. Two things I like about ours are the location and proximity to the outside clothesline and the natural light and unrestricted space around the cupboard. I wouldn't find it as nice to use if I only had a narrow space to manoeuvre. You will also need to consider ventilation for the dryer (if you haven't already).

Hi there, I think that the skylight would definitely be the way to go, if your budget runs to it. It will really lift the whole stairwell and make it much lighter and brighter. Full height frosted doors may be OK on the laundry, but I wouldn't recommend it for the bathroom as when lights are on in the room, you may be able to see more than you bargained for, from the corridor. The occupants of the house may feel comfortable with it, but any guests or visitors may not. A frosted panel at the top of the door would be as far as I'd go. Bear in mind too, that glass lets more sound through than timber, and in a situation like yours, I'd recommend a solid core door, for that reason. I hope this helps!

Hi Paul In apartments, the killer for layout changes are always drains, then water supply, then load bearing walls. Before you consider doing any changes to the layout, I would advise you to locate the drains (pics would be good) as they will likely restrict you. The drains are important for obvious reasons but also important is the fall (ie downward slope) of any drain you wish to install in a separate location. It means you have to take into account more height the further away from the existing drain you go. It is likely that your existing laundry trough/basin has a drain going down to the floor, and this is going to interfere with the proposed ensuite entry location. Ditto if it is going into the wall. The big one is the new shower. It will need to have a 50mm waste (drain) in the centre of where your washing machine now is.... and the question is where is it going to go.... I would suggest swapping the vanity and shower over to access the existing trough waste if it is large enough. In a lot of these older apartment buildings, the waste sizes are down at 38mm, which is not going to drain fast enough for a shower. If your existing waste is that size, you will need to have a hob to the shower as it will fill up, and you will also need to check health regs to see if it is allowed in your state. To get the drain for the new ensuite vanity and new laundrette sorted, I would punch through the new kitchen wall and run drainage along the wall behind the new cupboards and around to the existing kitchen sink waste. This will give you plenty of fall and a place to hide the pipes. For the new basin to the existing, you will need to see if you can get it around to the existing basin waste in the bathroom adjacent by running it around and under the bath. Cheers
