I like the timber doors. Stick with them! No, They're not popular at the moment but I'd say thats more due to the cost when compared to a mass produced coloured/laminated/painted door which would be milled MDF or melamine and the like. Solid timber is just that, solid timber not some manufactured timber of an unknown quality. I'd go for tiles every time on a floor in a wet area. Genuine marble as a splash back would be awesome in a laundry, get a price as you may be surprised as it's not a huge area. Tiling does add up quite quickly.....

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!

Your renovations are well underway, so after seeing the small floor plan and that the vanity is on an internal wall and you apparently still want the Shaving Cabinet. Having cavity brick walls I would get your brickie to remove a section of the brick wall so that the shaving cabinet can be recessed back into the cavity, this will overcome any concerns you have about bumping your head, this opening can then be patched along with other walls. I would take all of your photos and measurements to someone like Reece to pick a hand basin to fit,, I would also keep in mind that if say the width of the vanity is around 900 the shaving cabinet would match that width and you would end up with say 2 x 450 mirrored doors, which puts the mirror join in the middle and in your face when using the vanity. cheers

Hi I have a large bathroom with a closet for washer and dryer. I love it. Off my bedroom. But also have you thought about making study into bedroom with an en-suite and the laundry tucked in there behind doors. If your selling a bedroom downstairs for an older person its very attractive and nice to be separate from the others. Then the two bedrooms upstairs have there own bathroom. Also you are having toilet tucked under staircase for visitors. If you had heaps of space then yes have a separate laundry but it’s a waste of space when you haven’t. I have my laundry essentials in a cupboard under my bathroom vanity which is 1800 cm long and still have two 1m drawers next to cupboard.
