I'd turn the bath 90 degrees to along the right hand wall. Then I'd add a WC. You have plenty of space.

Personally, I think J’s suggestion of bath location is right. I would place toilet on outside wall which makes soil pipe run easier and vanity opposite windows so you can have mirror and extra storage above.

FWIW IF a WC is going in there the soil pipe is coming towards the door rather than the window side.

Its a big if - there is already a WC just across the corridor outside that door in a separate shower room.

I agree with angelavdavis, a toilet is a must in a bathroom. You have a great space for the bathroom and it would look strange not having one in there. J’s suggestion for putting the bath on the end wall ensures plenty of space for the toilet and vanity. I would also suggest having wall hung vanity and toilet if you want to make it feel even more spacious.

You say there's a shower room with toilet across the hall. But how many bedrooms does the house have? Is this the second bath? Is there a seperate toilet+basin in the house as well?

Some ideas.

My personal preference is the offset corner bath, as it leaves more space to move around, towel radiator could go behind the door, shaving mirror next to the window, two 90cm vanities side by side (one with sink, one with full depth drawers) under one top.

Hi, really appreciate responses - it always helps having another pair of eyes find options - Thank you.

Current facilities

3/4 bed house (4th is a study right now), 2 of us live here, but potentially still a 4 bed house.

1. Existing shower+WC room across the hall from this room

2. Master bed has ensuite+bath+WC in the eaves.

3. Outside WC (useful when gardening),

4. Utility room WC(which will eventually go).

...but no 'luxury, spend a while soaking' bathroom as such - hence the project, and hence the lack of urgency on another WC.

Imagine a farmhouse extended and messed with since the 1830s, include 1960s timber extension and you get an idea of what I'm working with - certainly not going to gut it and start again, more add more modern features as we go.

WC or not WC?

I do get it - if I can get a WC in there it will work better and be a more obvious room setup. Obv a WC will fit - its the logistics of a fat soil pipe vs. the relatively easy 22mm feeds and/or 50mm bath/basin wastes. (would rather not have one than add in black water pumps mindyou)

@rinked - your bottom right option is my fave - bath on the bottom wall - however - depending on the end you're either looking up at the neighbours or at a wall, and its a shame to waste the view! (I fully realise you coulnd't possibly know whats out the window :) )

My wife prefers bath under the window - head on left end which gives a view of a willow tree and sky.

Current thinking

Resorted to mk1 paper CAD and moving scraps of graph paper around! (its quicker than sketchup)

Not sure if this is legible - bath under the window, back to wall oval - loo next to the basin (obv. egonomic reasons) and a wider 1m basin vanity. Diagonal thing top left is a nominal chair.

Storage need not be built in and potentially behind the door/on that door wall.
