Non standard toilet spigot help

[soulman63]

We just bought an older property and the installed toilet has a 180mm spigot height with a lash up waste pipe going to a 200mm high egress to the soil stack. Anyone know of a 200mm high pan? Spent hours on Google to no avail.

Alternatively any advice on a hardwood plinth perhaps to raise the height? Hate the ready made plinths shaped to the toilet I’ve seen. Or some better connector that may help?

Thanks

Jim

OP,
How come the previous owners presumably used the old WC?
Why not post a pic showing the WC spigot - the connector - and the soil pipe inlet?
Where are you taking your measurements from - to?

Ref. a packing piece - they are cut to the WC footprint, and have the edges painted with say three coats of white paint.

Sounds like the usual issue with a Horizontal outlet pan replacing a P trap pan.

The best solution is to try and lower the soil pipe to suit, presume though it's cast iron? Photo of what you have will help, see if there is enough available to cut back and get the fall you need from pan to wall.

Yep it’s the old cast iron soil stack so I’d prefer not to have to change it. The toilet does flush but needs three flushes to clear the pan and the water rises quite high. I’ll take a couple of pics of the set up and post here shortly

OP,
Remove the WC out of the way. Hire a 9" angle grinder with a metal cutting disc. Cut the projecting CI soil pipe at the wall. Doing this will lower the 200mm, & maybe, with luck, you will lose 20mm?
Whatever, you would only have a little to make up.
If you tile your bathroom floor with backer board & tiles under the WC pan then you will easily make up the height - but its still best to remove the CI stub.
Can the strange rounded bulge below the CI stub also be removed?
