Hi grieve-ann, know how you feel with the stressoutness, too many decisions to make all at once??! Agree with OnePlan, planning is key, depending on how long you plan to stay in this home, how much you spend doing that and getting it right for you. The better and clearer your plans, the easier your kitchen will be to install, too. If you are using a kitchen designer surely they should know what to do to solve this dilemma for you? You can also go online to magnet or ikea and do your own 3d plan with correct measurements and doors, pipeworks etc in correct places, then change the units and appliances around to play with how you want things...it's really fun! From personal experience we have boxed in pipework in a corner of our kitchen which we are used to now and never notice! But definitely central/ symmetrical is the way to go as far as possible. Also put your dishwasher as near your sink as possible...it's so much easier to rinse plates, tip the last bit of the coke you haven't finished away, etc etc! If you're not planning on a breakfast bar could you extend the sink run a bit to be level with the tall cabinets the other side? (these look great btw and are very useful!) Ie because you wouldn't need the overhang of worktop shown in the 3d pics. Sorry for the looonng post!! Hope it helps!

Painting them both black or white would definitely help make them look a bit more streamlined. I wouldn't combine the soil stack and downpipes as it could create venting issues and increase risk of blockage

Are the curtains and blinds hung so as to maximise light i.e. Wide poles and blinds hung outside of the recess if possible? Plants are meant to be good for everybody so you could add some if you don't already. I don't know what colours are in the room but a bright colour for accessories including cushions such as yellow may also work. I know you have a window but people with windowless rooms also like a window style mirror just to give that feeling. Not light related but perhaps some "sunnier" art i.e. Vintage travel posters or a coastal scene. I'd definitely paint the beams though as they can be a bit oppressive. And Nadolig Llawen to you too :)

It's already tight, it would look silly moving the toilet and basin toward the shower and putting the bath central. Even if you could squeeze it in the lip of the bath looks like it would almost be touching the basin edge creating a corner of the room you can't reach. I don't think you need to worry about putting it central even if you did it wouldn't line up with the window so something has to be off. I've literally just had my bathroom done and my bath is in the corner like yours on the same wall as the toilet. It's off centre from the wall and the window but looks fine. All you need to do is fill the corner, I like the plant idea but you could also use some sort of storage unit One other thing is that you could perhaps move the freestanding? taps to the corner edge of the bath. I did this and think it looks good. That way nothing is central but your taps might not be high enough
