First of all thanks workshop community for helping and guiding towards successful renovation of my bathroom.
I have an old house which has a laundry and toilet attached to main building and both have a separate door. The dimensions of toilet are 2400*1000mm and dimension for Laundry are 2400*1350mm.
I plan to remove the middle wall and keep only door. I also plan to add a shower area to the new space created(2400*2400 roughly) after removing the wall. The ceiling height is a concern and it seems cant install big exhaust fan in that so it will to go in wall. Is this enough space for bathroom, toilet and laundry combo or it should not install the shower area inside this one. Suggestions are welcome. I have uploaded the images.
I suggest closing off the toilet door and create a shower wet area in that corner in front of the toilet. Keep the toilet where it is so that you don't have to pay extra plumbing for moving the toilet waste pipe. Remove the traditional laundry tub and make sure to get a good deal on it on gumtree. Transfer the laundry tapware to the other side where the washing machine is. remove your current pantry and replace with a narrow unit. This gives the illusion that the room is bigger. a nice bright bench top will always give the room a bigger feel, same goes with the laundry cabinets. Give your bathroom a nice modern touch with an above counter basin along with a goose neck basin mixer. Let's not forget the towel rail and the exhaust fan. I've placed timber looking tiles for your flooring so that it does not look so harsh and gives it a nice organic feel that goes with the style of the house, we don't want it to look too modern. I suggest re-lining the entire bathroom with gib aqualine for maximum protection. As for your wet area full water proofing for the entire shower area. It is very important that you have adequate ventilation in your shower area, I suggest a whirly bird right on top of the roof and an intake grill on the ceiling. This will provide continuous air flow in the laundry area and prevent moisture buildup which leads to mold growth and infestation. Placing a timber louver vent at the bottom of your current bathroom door will also provide added ventilation. I suggest LED running lights in moisture proof casings to provide illumination in your new bathroom. Keep the hot and cold taps for your shower, curious you say? It is much easier to repair a traditional pair of hot and cold taps with new jumper valves than to call out a plumber and tear out half your tiling to repair a faulty integrated shower mixer. But in this matter the choice is yours. I've measured the shower at 900 x 900 and placed a standard glass panel at 1800 x 900. My final suggestion is to reverse the opening of your bathroom door from going in to coming out. This will allow you to place cabinets all the way up to the frame of the door without having to worry about door clearance. Enjoy the pictures, tell me what you think. Cheers!
