Toilet help

[dba7108]

I want to put a hidden cistern toilet in but a plumber I've spoken to says I will need to dig the floor up as there isn't enough pipe coming put the ground for the waste. I'm quite confident in diy and not totally sure what he means. I also need to connect a 32mm sink waste so would need something like below to attach on. Any advice please! The toilet brown waste pipe comes out about 2 inches.

I just got the 5 in 1 Solido with the Grohe toilet pan for £280 on ebay, all good. It's just gone on offer in Costco at £249 ish at the mo if you're a member

Mine only comes out about that far and its fine, I did connect it with a normal elbow though (no waste)

I think the opposite is true !
You will need to be careful with the height to the soil pipe bend on the frame .
You’re intending installing that boss pipe then a 110 mm reducer to 90mm then the bend which clamps to the concealed frame

The blackbit looks like an inline connector, can you remove it? then use the item you showed and the height should be about right?

I had a mare with mine too, turns out I had a weird offset adapter on it, once I cut it off I just fitted an "old money" to new push fit and slid the toilet waste in. This was waste through the wall not floor though.

The problem i have speaking to the plumber again is that I can't put the sink waste in to that toilet waste as il need a flexible pipe to connect to the toilet.

So I'm thinking of using the old sink hole which is in the floor but will need to be dug out to hide it in the floor/wall. Can I just channel the floor out and remove the dpm and connect the pipe up. I'm assuming I shouldn't back fill the new pipe as this could create a bridge for damp to enter house?

If you have the space in the room you should be able to bring the WC frame forward and then change the outlet to a horizontal section before returning down to the soil pipe in the floor. I think Grohe even sell the kit to do this.

If you need to run a washbasin waste into this then a strap on boss should do the trick.
