correct measurements are the only answer...for your new floorplan you need a room (without any restrictions that would measure at least 2400mm x 2000...it's always possible to squeeze in some minor variations but only if it's worth the cost in convenience, improved value of the property and actual cash outlay.... the front door entry foyer would be lost, the new bathroom doorway wastes more space, the linen cupboards would be too narrow for anything except a few towels and sheets (that can easily be stored in a suitable vanity or bedroom cupboard) the bathtub is gone and you would have spent about $20,000 for a bathroom that is not better than what's already there?? ...the computer programs that we use are called 3D Home Architect and my version 4 is no longer available to buy but i believe siriuskey may have purchased her version recently? these programs do make the plans much easier to see but you must start with accurate measurements and an understanding of spaces needed ...start with a space about 800 x 800 mm for a toilet, 900 x 900mm for a basic shower, 500 x 900 for a single handbasin 1500 x 500 for a double handbasin then add in at least 900 x 900 for a doorway (including space for the frame and space to walk through...same for cavity sliders!) and then you'll need space to walk around in front of the toilet and shower and handbasins ......unfortunately with the plumbing and space restrictions i don't believe it's possible to do more than widen the existing shower space by rearranging the entry wall.(NB you'll still need to spend $5000 to $10,000 for demolition, carpentry, new waterproofing, tiles, shower, vanities wall cabinet, taps, plumbing etc..forget the linen cabinet and store linen in a new vanity and toiletries in a wall hung mirror doored cabinet and keep some width in the entry foyer (minimu 1200 wide) ...removing some of the non structural wall in the kitchen should be the cheapest improvement for the kitchen and add space for a small breakfast bar but removing the end counter would lose valuable counter space that could also be used for a pantry ...before making any decision you need to think about the reason for the changes...are the bathroom, laundry and kitchen in need of immediate repair, is the unit for your own use of needing improvements for rental or resale...?? always happy to draw up your plans but have to nag again about the accurate measurements...try measuring each separate room (ie shower, toilet and vanity, laundry and storage from wall to opposite wall in several places in both directions, ignoring all the fittings but include separate measurement of the diameter of the hot water heater.

subject to confirmation by a plumber your new layout should be ideal with just enough space for a stacked washer and dryer and skinny tub and wall shelf for the laundry (i'm assuming the old shower position also has taps and floor waste) and a 1500 wide vanity with storage for linen and mirror doored medicine cabinet but what is the triangular space?? there could be wall thickeness to use for stacked doors for the laundry instaed of the bifolds btw a floating (wall hung) vanity is usually more expensive, creates problems hiding the pipes and will lose valuable storage space for towels and lineni would expect a full reno with modest quality fixtures and tiles and no surprises to cost at least $20,000 but suggest that a bathroom company that could take responsibility for organising demolition, plumbing, carpentry, waterproofing, tiling electrical, painting and sourcing the tiles, taps, screens, lightfittings, tubs, doors etc may be worthwhile and save you trying to juggle the trades who are less likely to be dependable for a single customer although with available time you may be able to save some money by removing old tiles and carting away rubble and finding the tiles. taps, vanity etcs and having them ready on site but coordinating all the trades can be a problem especially if you don't have an alternative bathroom although it's always good to be on site to supervise the work and answer any last minute questions

Before falling in love with some beautiful bathroom photography you really need to take a step back and think about the day-to-day practicalities and your budget. Is this the only bathroom in the house, or is there an ensuite? Is there a separate toilet, or do you need a toilet in the bathroom? Do you have young kids who need to be bathed? Do you need a bath in this room, or is there another one in the house? As an adult do you like to have a long soak in a big bath, or do you always have showers? Do you need bathroom storage for make-up, towels or toilet rolls? The answers to these questions will help you decide on the right fittings for your new bathroom. Many people would prefer to have a larger shower and a smaller bath, but it depends on your household and preferences. The shower over bath is not a good option if you are a regular shower user, but not a regular bath user. It is also quite difficult to bath a toddler safely with a fixed screen in the shower over bath situation. Many people who love the look of the walk in shower with no door, such as in your first photo, end up hating them when they start using them. If not carefully designed and built they can swamp the bathroom everytime the shower is used, so do your research. Your bathroom is also too small to have a freestanding bath (as in the first photo) as you won't have enough room around the back and sides to clean the floor properly. You are better off with a bath built into a bath hob which is in the second photo. Best of luck with your considerations, Dr Retro of Dr Retro House Calls

Yes, siriuskey. You are right again. It would be smart to invest in having a professional draftsman draw it up. But on face value, I really think oklouise's plan works. I have sort of drawn it out on the floor. I love that she is using standard size vanities with only a custom made top, and the towel shelves are now 450 instead of 250 wide, which is much better. The little odd-shaped infill at the end of the bath provides a spot for the lovely jug and bowl set my mother made for me. (I used to use the jug to pour water over the grandchildren's heads when I washed their hair, and now it's just a lovely decorative item with deep sentimental value) and there is space beside the bath for the urn filled with decorative soaps that was a gift from a son-in-law on his first visit to our home. I really think the bath needs to come back to 1500 long, but that's not an issue at all. I found a really nice shaped oval tub at 1500 x 760 that I like and is quite inexpensive. I don't need to worry about towel rails because I have a lovely timber free-standing towel rack that will fit nicely at the end of the shower if the shower door is placed on the side. It looks like the vanity drain can run under the drawers and into the bath outlet and the WC vanity will run under the wall into the shower drain, and all other plumbing stays the same except I'll ask the plumber to chase the shower tap and rose into the exterior wall rather than have it on the side, OR there is room for a false wall in front of the exterior wall to hide the plumbing if that works out better. The niche can go in the new wall behind the WC vanity. I'll be really surprised if this isn't a feasible plan, but I will take your advice, siriuskey, and get a pro to draw it up so I can be totally confident it works. Can't thank you enough, oklouise - and you, siriuskey, for all your efforts which, I think, contributed by generating new ideas and flushing out the important issues.
