I have a shower over bath combo' which its plastic resin something? It's a old bungalow and pitifully small. The amount of times I have nearly slipped over getting out, or lost my balance with soap in my eyes/ or after having a glass of wine. hate hate it. I did see a shower room with a additional hand held device and a over head shower. I thought that good for the odd squirt your feet down. The next owners will probably rip it all out and start again any way when design ideas change.

As I was using the same tiles, vanities etc and tradesmen at the same for both the bathrooms downstairs, it helped reduce the cost. I would say roughly $15,000 per bathroom and that also included getting the expensive Italian feature tiles and the scones/ wall lights weren't cheap either. If you design cleverly, you can purchase most items at a good price, then shell out a bit for the wow factor pieces!

I like what you have done i this bathroom, there is only one thing that could have been done better and that’s the position of the mixer tap for the shower. You should have access to it without getting wet , so it should have been positioned on the back wall closer to the towel hook. So you can turn it on and wait for correct water temperature before you get in.

I hope you don't mind... seeing the external pics I have a totally different idea! But don't worry I don't expect you to actually use it, and it's just a rough sketch. You don't need to extend the footprint at all in my opinion. based on the picture of the front of house your drawing is a bit out... the entry stair actually sits to the left of the front door I think. so there is a little more room there, but i'm not sure if its wide enough. So maybe there is enough room to put a hallway back in and create a master suite upstairs? The front deck becomes a private retreat and I put the bath out there! It's only accessible from the master and bed 4. If you don't need that many bedrooms maybe even leave the master and bed 4 combined and have a huuuuge master area. there's still the study downstairs that could also be a spare bedroom. I thought as the front deck is so private it could be really luxurious. The old kitchen becomes the walk-through robe and ensuite. The new kitchen goes straight under the old, and the kitchenette becomes the bathroom,accessible from the pool. the downstairs kitchen is connected to the dining and living, but the posts define the areas. The kitchen can have a halfwall with a servery-style opening between the posts, and will still have that connection. I didn't draw it in on the downstairs picture, but the entry needs to be pushed a little forward and then the stairs run up from the left corner and arrive where the original entry was upstairs. The downstairs living is accessed straight from the entry at front and opens onto the front patio, under the back deck becomes the back patio. I feel like you have less new to build and retain more of the original layout. in fact the upstairs bathroom is entirely intact.
