Installing a new lavatory

[Dave Baker]

I'm looking at fitting a new bathroom suite soon and the only bit I'm not sure about is in fitting a new loo and what happens if that doesn't fit against the wall and the waste position needs changing. I guess that involves a major digging exercise down to the sewer and laying new pipes. From the wall to the centre of the current ceramic waste is 25cm. Is that some sort of standard dimension which means that any new loo will abut the wall properly?

Easiest thing is to get a loo with the outlet horizontal out of the back rather than using an S-trap and trying to line up the bottom outlet. Then use adapter to connect to loo to the waste pipe in the floor. A new close-coupled loo with the cistern behind the seat will usually end up futher from the wall. Simon.

Also doing a bathroom and also have a high level loo with bottom outlet that will be changed to a close coupled unit. I don't think there is any standard, I did have a look through "The Blue Book"

(be warned it's fussy about browsers...) at bottom outlet loos and they all appeared to have different wall to outlet distances and that's from the same maker!

I've went for a horizontal outlet and resigned myself to the work required to get soil plumbed. Then wandering around the builders merchants (as you do) I saw a Hunterplastics S234. Second connector down on

This should

*just* sort my problem out. In theory the solid pan base overlaps the pipe in the floor by 10mm, but the wall isn't tiled yet... It'll still be tight but within acceptable ranges I hope.

Not sure of your specific dimensions, but have a look at

- they (and I would think most plumbers merchants, TBH) stock any number of adaptors between clay and plastic pipes, including some with flexible couplings and/or offset centres. I'd be surprised if there wasn't something there to suit.

Does the existing soil pipe exit the loo horizontally through the back wall, or downwards into the floor (the latter is more problematical I'd have thought)
