my 2 bobs worth. as someone who works with the elderly-the en-suite for your MIL is still not right. if she ever needs walking assistance,especially with a frame, getting past that door into the en-suite will be a nightmare. swap the vanity position for the shower. ensure there is no step-down into the shower area, and ditch the shower screen for a curtain. will make access much easier. especially if she ever needs assistance showering..it will be virtually impossible, and dangerous, with your current design. thinking long term..MIL will not always be there with you, so presumably you and your hubby will at some point end up in the master bedroom? consider the long terms implications of this-no good building something that suits her now, but would need major modification to suit your needs later. I would actually do away with the WIR at this time. Plan to add it later, if you would want it for yourself, but i would just use free standing furniture for her-no doubt she probably has her own, so it would be nice to have some of her own furnishings when she moves in with you - to make it feel more like her home. it will free up some floor space, and make access to the ensuite easier, without having to turn corners. I would also do away with the extended passage into the master. Take that door back in line with the other bedroom. Currently, it adds nothing, and may well limit your furniture placement for your family room, as the walkway will need to go around it. i have issue with the 2 person shower and double vanity in the same room. s the kids get older, they /you probably wont be comfortable using the room when you are showering, so mornings will be slowed down. Have you considered a 3 way bathroom/toilet/vanity area? We had this in our house, and it was the best decision ever. The shower and bath were in one room, with a separate toilet, and then a double vanity which opened to the passage. Everyone could use everything at the same time, without encroaching on each others privacy. Not sure about your state -but here, the toilet door would have to open out-if someone collapses in the powder room, you would not be able to get in with the door opening in, as they would be blocking the door. I do empathize with your dilemmas. We have spent 7 years planning an extension and remodel, then 2 years (!!!) working on the design with an architect, going backwards and forwards, and then the last 12 months nearly, changing and fine-tuning along the way as things were being built. It is not easy, but worth it. Having said that, you are unlikely to ever get it perfect, as your needs will change, your likes/dislikes will vary, and you will see other peoples homes and go "why didn't we do that". (Now if only i could take that on board myself, LOL)

How's it going ? U in yet? You loving the country life? Great flower stalls on that road, or use to be! $2 bunches.. Can you look at my 'tiny house' the size of your powder room..lol https://www.houzz.com.au/discussions/6042198/those-with-an-eye-for-colour If you have any other ideas. I got some good ones already. But throw any more around that you think might work.

Small bathroom and a small budget - go with a framed screen. Fixed glass, frameless panels look great, but are high end products that are expensive to make and to install. Go and do some comparison shopping and you will be surprised at the difference. You can then decide if it is worth your while spending all that extra money for that look. You will also need to carefully consider your splash distance with your open shower. Think about how much water will splash outside the shower area, and how much you like mopping the floor after every shower. So many people have been caught trying to achieve the same modern and open look in a small bathroom and now wish they had a shower door whenever they have a shower. Make sure that you have an additional floor waste outside the shower area for any overflow before the run-off reaches your door threshold. So many things to consider when renovating a small bathroom, and oversights can be expensive. Best of luck, Dr Retro of Dr Retro House Calls.

check out any glass company that specialises in shower screens..phone around as it should be quite simple although be prepared for a good price and worthwhile to get a quote on a standard screen for the same space so that you have an idea of how much more you will need to pay for the arch
