Online bathroom planning apps?

[WhereDoesThisToiletGo]

As per my username, I am about to embark on planning and installing a new bathroom.
Storage is important so I plan to use a vanity and some other furniture / wall cabinets.

Can anyone recommend a good (preferably free) planner?
I've done the cutting bits of paper out trick, so I have rough idea what will fit but I'd like to be able to see it in 3D.
I've tried B&Q planner and can't even get the door in the right place, and the toilet is currently 'placed' on top of the vanity unit!
The stuff I like is from Victoria Plum who don't do an online planner.

Many thanks

Watching with interest as we’re planning the same.

@Lunaballoon I should have put this question in AIBU!

Watching too!

I actually went in to B&Q and a helpful bloke did a 3D plan for me which gave me some really good (completely obvious which hadn't occurred to me) ideas. We used similar units in the exact size as the Victoria Plum stuff I like.
Well worth doing - I was convinced that I wanted a back to wall loo with concealed cistern, but seeing the 3D plan, I could see that a standard close coupled loo looked much better.

Yes the concealed cystern actually means ilose space (I think!)

I know cphart do 2d technical plans and a full design service with a fully qualified interior designer for £350 or £600 for 3d aswell. We used the manchester showroom and their expertise were incredible!
