90mm to 110mm toilet waste connection

[cwr]

For connecting up the toilet in the caravan that's just arrived, there's a 90mm dia pipe coming down through the floor. Is this a standard size that a straight toilet pan connector will fit? 

 

I can find some rubber adapters online, but at around £25 seem expensive for what they are.

 

Thanks.

somethign like this which I'd imagine Toolstation or Screwfix would do to? https://skyplastics.co.uk/110-122mm-x-80-95mm-flexible-adaptor.html?gclid=CjwKCAjwz_WGBhA1EiwAUAxIcY5OPpQ1hcbGKiiqFKlBFzuZz32FVvvHwXM0VNnVskqDOllOUt5ISRoC1EwQAvD_BwE

Personally I would strip out what you have there right back to the pan and start with a standard pan connector  and work from that.

The McAlpine fittings are much better quality than the Floplast stuff. Dimns of a couple of McAlpine connectors for instance:

Yes that would work, just wondering if there's a cheaper way to do it. £22.20 inc postage. Gotta save the pennies to pay for that kitchen...

Use a rubber joint as @Vijay has pointed out - about a tenner from most places.

Is the toilet pan already in and the 90mm pipe comes off of it and down through the floor?

 

If so how about this, £5.98 from Toolstation. Link just for better info:
