As OnePlan says, layout works & not being greeted by a wc is a bonus! Get the lighting right & it won't be a problem not having a window. I would recommend having lighting switched separately as well as extractor fan,with secondary lighting for when you may need to use the wc in the night etc & don't want to be blinded by the main lights - wall lights or LEDs at low level under vanity unit, left wall & right wall from end of bath to wc for example. Invest in a mirrored cabinet with integrated lighting & shaver socket & would recommend a large mirror on the left wall to make the room feel more spacious. We have fitted a mirror from ikea several times on previous projects, 2m x 80cm for £80. Regarding tile choice I wouldn't be to concerned about the finish of the tile if your lighting is right. I have gone with the same tile for both walls & floor in ensuite & small bathrooms which helps the room feel bigger. Whites & neutral tones are always a winner in smaller spaces. Hope the above helps & good luck with your project, put up some photos once you have completed it! Regards Karl

Thanks active builders, I thought 1.8m depth for the wet area - assuming bath is 80cm wide that leaves 1m depth for the showering area, but then that only leaves 1.2m to fit basin and toilet, which I thought might be a bit tight? We don’t really want a small basin as this is the main bathroom. My other option is to have toilet and washbasin opposite each other in the 1.2m run, but then this leaves a 80cm gap between toilet and washbasin and not sure if this would look a bit cramped?

Options then would be:- putting them on the shorter wall opposite the sink: 800 wide shower (or 700) but 1m length coming out into the room as the entry door is offset. That gives a good sized shower. Then you have 1m tub space to play with for a deep tub. Then I would put the WC and sink on the other short wall so entry into the tub isn’t hindered. 1200 or 1300 tub on the 2m back wall with an 800 or 700 wide corner shower. Actually you could potentially have it so the wc is far left back wall with 1500 bath opposite the door and then a corner shower far right side. It’s all a bit cramped though with a standard or even small sized tub so do consider a shower over bath. You can get short rise baths if it’s an issue with getting in/out that’s the issue. Also shower baths with 800 shower area if it’s shower experience

I'm just about to buy a hour with EXACTLY the same issue (and exactly the same floor plan!!!) I have looked online at turning the bath around to go under the window & moving the toilet but it seems like quite a big job so I'm wondering if I could move the bath to immediately inside the door and the sink up near the toilet?!
