Fitting a Macerator behind a CC Toilet

[LesW]

Hi Guys
I am at the design stage of having a En-Suite built and have an issue that I cannot seem to resolve.
For long and complex reasons I have to have a macerator and that needs to sit behind a close coupled toilet.
this will take the waste from a sink, shower and toilet.

Saniflow say I need 190 mm between the wall and the toilet spigot, difficult to achieve.

Grudfos do a unit called Sololift WC3 that has a recessed front that suggests it might fit behind better but as I cannot get to speak to anyone at Grundfos other than an automated messaging system, I cannot confirm this.

So my question is, have any plumbers on the forum had issues fitting either Saniflow or Grundfos units behind close coupled toilets (without having to pack out the toilets from the wall). If so how did you resolve it and what model macerators did you use?

Thanks in anticipation

may be that 190mm is so you can change it in future but if you push up against wall if you needed to change it you would have to remove wc maybe.

190mm sounds about the depth of the unit, so if you want it behind the toilet, you’ve got no option.

I guess you could cut into the wall and create a slight recess of maybe 30mm or so to gain a bit.

Or build a boxing and bring the toilet forward.

Or build frame work/boxing for a wall mounted toilet frame.

Or reposition the sani, it doesn’t have to have the toilet connected direct. Maybe put sani in basin vanity and pipe toilet to it.

Or put sani in adjacent room (bottom of wardrobe).

Just some ideas without knowing the layout.

Thanks for the response. I have flirted with all your suggestions (other than the wardrobe).
I am still perplexed that both Saniflow and Grundfos market macerators that are supposed to fit behind close coupled toilets (as shown in lots of their documentation) and haven't first researched the typical envelope the unit needs to fit in ???

Like for every toilet in the world you mean! What is your objection to a baton behind the cistern? If it is that strong then build a false wall, recess it in to a wall or find another way (there is usually a way 9/10 times), fit an all in one model or consider something like the Sanipack that sits to one side (if it takes water from the shower that is) but dont throw the toys out of the pram.

Dear RPM
In my professional life my maxim was don’t solve problems, avoid them in the first place. Imagine a car manufacturer placing the foot pedals too far away and suggest you could tie blocks of wood to them so you can reach. Packing out toilet with a piece of wood isn’t a solution it’s botch-up.
I hope my plumber is more creative.

Of course there are lots of more elegant solutions, I could place the macerator in a vanity unit and fit a back to wall unit and other helpful contributions from forum members have been appreciated.

It’s an irritation not a problem and will be solved, I just wondered if anyone in the forum had come across the issue.

Thanks for your comments and both the baby and bath water are safe, we are fitting a shower.
