any drainage points

I'm not sure? Sorry - haven't much knowledge or experience! As far as I can tell, the only existing drainage point is for the laundry tub. Is there anything else I can look for?

It's a brick veneer house, on stumps, if that is relevant.

your floorplan looks good but i think the most economical version would be to leave the toilet as is, try to reduce the impact of the pocket door and use an acryliic shower base and walls with a curtain or adjustable width glass door(available diy on line) rather than attempting to create drainage and waterproofing for a walk in shower with tiled walls ...depending on the exact size of the pocket door it's possible to reduce the width of the opening by preventing the door sliding fully open from the laundry side (so you can add a narrow covering wall over part of the door opening to increase the depth of the shower from 720mm) and then have the cover plate to remove the door changed to the other side..(you can test this theory by putting a nail in the door to stop it sliding inside the wall further than you want) having said all that, we've successfully used a 60cm deep shower in an awkward space but avoiding tiles and structural alterations will be the biggest savings

Do you have a full floorplan that you can post to give us a better idea of what might work, what climate to you live in, could you have an outdoor shower

Thanks oklouise, some very helpful suggestions there. I put the walk in shower option in because I thought that might make the tight space more manageable, but agree that an acrylic base is the more economical option. Will have a look tonight to see what we can do about limiting the sliding door. I'd imagine if we can limit the opening to about 750mm for the door, it'd give us the extra 100-150mm or so for the shower which makes it quite decent.

Siriuskey - floor plan of the house is attached. We are in Melbourne, so outdoor shower is not an option in winter, especially for the kid!

certainly not, you could look at using a barn door which would free up space by making the doorway opening wider to wards the exterior wall. I did ask but it appears that there aren't any floor drains within the space. OK I had another look at those acrylic shower bases before, but you would still need a floor drain?.

If the doorway is reduced to 750 and using a Barn Door it could work as a euro style bath room, you would still need to sort a drain and if there's no slope on the floor you might need to add a brick height retainer across the end of the glass shower.

Barn door is a great idea too, thanks.

From what I understand, we have to add a drain wherever we put the shower. Hopefully it isn’t too much of a hassle or too costly to do.

Generally in terms of layout, it seems like shower in that corner is the way to go. We moved the direction of the washer/vanity combo so we can add a mirror or medicine cabinet to the wall, which wouldn’t be possible in the current position because of the window.

I did mean to run wall cabinets along the wall starting above the WC ending with mirrored shaving cabinets next to the washing machine and sink. more cost effective to keep things as they are, Are you doing a total on this room ie:: changing tiles etc

Not sure about the tiles etc - to be honest it just comes down to what we get quoted for the different jobs and whether we have the budget for it. I imagine there would be some degree of re-tiling required based on putting the shower in. We want to change the toilet, but i think that should be doable without changing floor tiles? And we want to swap the laundry tub for a proper bathroom vanity/ sink, with a bench top that continues over the washing machine to give us more usable space.

the problem with the drain for the shower is not the location of the shower and the hole in the floor it's the waterproofing and slope for drainage of a triled floor

we've seen this house before and probabaly suggested that any renovation include plans for the whole house rather than doing small changes without considering the rest eg do you want a proper 2nd bathroom or a laundry with a shower/toilet, do you want external access from this room or would you consider having external access from the family room or elsewhere..any renovation that has to be redone is too expensive and there will be better suggestions with more information including the correct dimensions of all the rooms

haven't checked dimensions, but we did a small ensuite like this, stole room for a nook for basin into adjacent room (laundry) and made the whole ensuite a wet area. still requires drainage, waterproofing and I did full height/floor tiles and you'd have to modify the WIR. just thinking outside the box...

I like Jo's idea. More expensive but better bang for your buck.

Thanks guys, a lot of really good suggestions there.

Make sure that your vanity "basin" will function properly (primarily) as a laundry sink/tub and isn't just suitable for hand washing/shaving, otherwise you'll be stuck should you need to hand wash clothing, soak or dye items, wash pets, or do any heavy duty cleaning (not necessarily of clothing) that requires a decent-size laundry tub.

Very good point Yvonne. We are thinking about using this one from Ikea, or anything similar if others have recommendations?

Ceramic is great. The trend for flat bottomed sinks with small radii is not very practical. They take a Lot more water to get any usable depth and are not easy to flush out when brushing teeth etc. if you go that way get a pull out tap to help flush sink.
