I agree with bigreader. A powder room should be discreet, but still easy for guests to find. Make sure that you don't have any sightlines, so if somebody does leave the door open you can't see the toilet pan from a a living area. Make sure you use a hinged door with a privacy lock, and never a cavity sliding door for a powder room.

A careful selection of sanitaryware, tapware and finishes, coupled with good lighting design is important to lift this tiny room above the average.

Best of luck,

design is always about balancing and a series of compromises - a floor plan reflects priorities one way or the other. IMO Powder rooms are best positioned with some degree of privacy - and certainly if possible not configured directly of a main hallway

You could have double thickness (2 sheets) of drywall on the wall shared with hallway. This will provide some degree of sound barrier.

I'd recommend you set-up with an airlock incorporated - positioning this off a hallway adjacent living area is certainly not ideal

no matter what you do to insulate the walls, use noise stop board, acoustic batts etc, the door and sealing of it will remain the weak point.....we recently achieved the positioning of this with a small airlock that had the basin in that - works well to protect/buffer the toilet from the main living

Do you have any original floor plan you can post, will this toilet be the only one. If there's enough space where the toilet comes off the hallway you could have a door opening off the hall and a hand basin for a powder room setup and then another into the WC for a good sound barrier. What space are you you considering

Two possible layouts for you

Hi - Thanks Siriuskey, yes the top one is what I would do if I go down this path.Still thinking... The powder room would be in the extension rather than the original part of the house, and there will also be a toilet in the family bathroom and in the ensuite.
