nomadicmel - I would not consider removing the window at all - ventilation is so important, or you will give yourself even more problems, especially if you are having a dryer in there. Have you given consideration to where that will be vented anyway. If you are planning ahead for teenagers (and good luck with that) having a bath in one room and a shower in the other will be a very good investment, teenagers are anal about their privacy, but do be very mindful of storage - a vanity in the laundry will really be important - just somewhere to put a hair dryer for example.

looked fab, you must be thrilled with all your hard work to achieve a great result, Congratulations.

Walk-in-showers are great for large bathrooms, but are problematic for small bathrooms. Even more so with a timber floor which does not comply with the regulations for waterproofness for wet areas. There are regulations in place that your waterproofing will need to comply with, as set out by the Building Code of Australia and Australian Standards (AS 3740-1994). You will need to do some research and speak to a professional as you are heading for disaster with the combination of a timber bathroom floor, a small bathroom, a walk-in shower, no waterproof membrane to protect the floor and no understanding of the legal requirements. Houses of the 1920's traditionally had tiled floors so I would be looking at one of my suppliers such as the Olde English Tile Company to help you source somethiing that is period appropriate and legal instead of timber floors.

You are going to have to spend some money to make it look seamless. Doing it cheap will always make it look like a crappy addition. There is no easy, cheap solution to your problem, and you will regret it as soon as it is finished. Best of luck, Dr Retro of Dr Retro House Calls
