Looking for a bit of advice here. I've smashed up the en-suite and have re-tiled etc, etc. Now, I'm in two minds whether to bother putting the toilet back I, due to the size of the room...it's tin. Then I thought I could get a smaller toilet, you know one of them new eco-friendly ones that seem to be a lot sleeker...well, smaller really.
Would the waste pipe be a) the same size and b)the same height off the floor? I'm without transport today so can't pop out anywhere to measure.

All help would be appreciated.

Cheers.

The outlet should be the same.I just did a search for slim toilets and came up with this page Here then did a search for the manufacturers which came up with This page. If you then click on the Technical illustration it gives the dimensions, etc of what you need to know.

I took out an old style toilet and replaced it with a built-in cistern (hidden in units under worktop) and new bog. The only tricky thing was connecting the soil pipe as none of the flexible pan connectors could fit in properly because the soil pipe came out of the wall quite a long way and the waste outlet of the toilet wasn't lining up but was quite close, meaning the flexi connector was in a very tight s-shape and I wasn't confident it would seat properly.

I took an angle grinder to the soil pipe, removing a few cms of it leaving it sticking out of the wall just far enough to get the flexi connector on.

Not sure that answers your question tbh!

I also had to re-arrange the cold water pipe to connect it to the new cistern, was all pretty easy.

depends how old your old loo and whether it was vertical or more common modern horizontal outlet. BUt dont bank on the connectors lining up, flexy connectors as menitoned are your friend!

I always tell the missus, a sink with a fast flowing tap and a pointy stick is a full ensuite! laugh

maybe, maybe not!

the one i fitted in the shower room was a perfect match for what was already there.

in the main bathroom i fitted a more modern looking one with concealed fittings. this was a complete pain in the arse to fit. it was quite compact so sat about 150mm back from the old one, meaning the soil pipe had to be extended back as well.

only problem with that was the floor joist in the way, so i had to investigate its load bearing and cut out a section of the joist. then i had to cut a section of porcelain out of the toilet base so that the flexi connector would seat properly. took all day just to fit a bloody toilet!

All day? Feck me, that would have taken me a week, before I kicked it to pieces and got someone in.

Modern pans are almost always 170mm centre horizontal outlets. There are, however, some which are more like 160mm so be careful and, of course, there are some 'S'-traps about which discharge into a concealed drain connector in the floor.
When connecting soil outlets avoid flexible connectors of any sort. I've removed too many to re-do the job properly to want to see many more of the bloody things. They tend to promote blockage and that's never a good thing.

Surely that's a bit of a generalisation - although you sound like you do it for a living in which case I'll bow to your superior knowledge as I'm just a diy'er that used one on our new loo 3 years ago! Ours has been fine, the water doesn't back up when flushing so I'm confident it's nice and free flowing. I'm sure some people bodge them on in less-than-ideal ways or weird angles though.

Every toilet I have ever fitted has been 180mm centre of the waste outlet.

One thing to bear in mind though is, if you had a high or low level cistern and pan before. The toilet pan may have been quite a distance away from the wall. Meaning your soil pipe may come through the wall at a lower distance.

Most new close coupled toilets allow the pan to be quite close to the wall. So your old waste pipe may not line up. If you have this trouble you can be plenty of waste connectors to overcome it. An off-set pan connector will be your best bet if you have trouble, as a flexible pan connector can't be used in a tight space.

Good Luck

I find most are a touch lower than that now, Ricky. More like 170mm although I did a site a couple of years ago where they were 160mm.

To be truthfully honest I've never actually measured one, I just always mark out 180 mm centre for the soil pipe and most of the time they fit without any hassle.

Thanks for pointing that out though, will have to remember to check!

Thanks mate. This is my main problem, the distance from the wall issue. The waste pipe is currently boxed in, and if I can help it I don't want to touch it!

Cheers.
