Hello

I really need some help on installing a downsairs WC. i'm turning my existing kitchen in to a hall way and converting my garage into the kitchen. As the hallway will be spacious due to taking a studwall down by the stairs I thought that it would be a good idea to install a small downstairs WC. the only problem (as im a little OCD) is as you come out of the living room door there will be a visual kink in the corridor leading to the hallway due to the wall sticking out where the downstairs WC is.

My question is, from a design perspective does the attached plan look plane silly due to a wall sticking out or would the house still have a good flow leading to the hall? I ideally wanted the WC under the stairs but would mean installing a saniflow system due to the soil pipe being the other side of the room so I think that this would be too much mither.

your opinions are appreciated, thanks again.

what ground floor construction is it?

If concrete you could locate WC under the stairs and cut a channel in the floor for toilet waste leading to soil stack.



edited to add downstairs wc needs to comply with part m of the building regs. Off the top of my head that means a min width of 1m. Do you have that in present location?

Can you zoom out a bit to get the full context.

Have you considered just peeing in the sink?

I would prefer it under the stairs really and it will be 1.2 deep metres by 0.74 width would this pass regs? I thought that was only for wheelchair users as it would probably be the same size as it being under stairs?
floor is concrete. would this not damage DPM?

If the boiler is currently and is intended to stay on the outside wall as signed, if you're planning a basin in the cloakroom you'll fall down on wiring regs.

hello and thank you for the reply. The boiler will most probably be incased in a cupboard, then a stud wall and a seperate cloakroom. will this be compliant and also reading on Part M this only seems to relate to extensions, alterations after a house was built in '92. Is this correct?

IMO don't rob space from the kitchen - if you really need a downstairs WC rob space from the garage or go with the Saniflow under the stairs

well luckily the existing kitchen will be in the garage. where the kitchen is now it will be a hallway. as this was a kitchen then it is very square so a downstairs loo will take up a lot of this space.
I just dont want it to look out of place when looking from the living room and see a protruding wall I like things to flow but will be a case of when walking through the hallway I will have to manoevre slightly to pass through where the stairs are.
Only other alternative is a saniflow so that I can position the toilet where I want in that room but I know I would be warning people of the system everytime they used it smile

Fused spur and associated wiring would need to be contained in the compartment housing the boiler. Providing the clearances around the unit are greater than those given by manufacturer and clear access for servicing and in event of emergency, don't see a problem with this. If it's a fresh install, whoever does the work can advise on the absolute compliance. My personal recommendation would be to resite in to new kitchen taking over garage space, pipe work to boiler rerun and cold feed will presumably move for washing machine, dishwasher and sink anyway?

As for Part M query, I'd need to read the relevant sections as its been a while, hopefully someone else can come along with an answer.

Thank you for the response. I literally just had a new boiler put in so would cost further money and leave me with 2 patches where the flue has been drilled through the brickwork smile.

What are peoples general opinion on having a wall protruding in the hallway? ie having a bit of an angled route near the stairs

Then go with compartment in cloakroom, just ensure whoever does it goes by the appliance manufacturers instructions on clearances.

I'd recommend getting the person who fitted the new boiler back to do a further safety cert, updating gas safe on the appliance installation location too. Depending on your location, this might cost you anywhere from £40 to the moon (based on the other thread about Pimloco Plumbers!)

Are you having the front door where the kitchen was? I don't think it would bother me having the downstairs wc sticking out depending on how the hallway is furnished.

Well it is just having it sticking out that I cant fathom if it would look wrong or not. Front door will be where the old kitchen window is. The plan is either a downstairs loo or put a nice cupboard wound the boiler, then have a nice sideboard and then on the opposite side of the wall where the stairs are, have some nice cupboards running along the wall for storage, ie ironing board, coats etc. Plenty of storage vs convenience for needing the loo. The decisions smile

It is to allow wheelchair users access to the WC. If you are adding the toilet as part of a building control application (assuming you are as part of garage conversion) then it will need to conform to regs.

Re DPM, depends on how deep the channel in the slab would need to be. If right through the slab then you would need to lap a new dpm on to existing.

I thought that this only applied to commercial premises? there is a toilet upstairs so why would the new toilet need to comply with the disabled? if it does need to comply then storage space it is as i have applied to building regs. Guessing most houses that have toilet under stairs have done this without regs.

it is a pain. Re other toilets under the stairs, regs do change over time. This is just current requirements.

After having had a look at the part m document you can get away with a 900mm wide toilet is access directly or a 850mm wide toilet if accessed from the side.

Reg in this case is Section 10 of Part M1, page 72

dont give up just yet, always worth speaking to your local building control.

Approved Document M does not apply to alterations to dwellings (assuming the OP is in England).
