Increase height of new toilet pan

[stefj]

I'm replacing my old toilet and cistern.

The flooring is P5 moisture resistant chipboard.

The new toilet pan is not as high as the old one and needs to be raised by about 25mm.

I'm proposing to screw a piece of P5 chipboard (22mm thick) to the floor and fix the pan on top of it.

As an alternative, I have some 12mm marine plywood that I could screw 2 pieces together to give 24mm thicknes.

Does anyone see any problems in doing this?

I would welcome any tips, suggestions.

Thank you.

Either would work, it's will stick out like a sore thumb a bit though. Floor covering dependent then Ply would be more resilient, especially if there are bad aimers in the house.

Don't see why it shouldn't work. Will the outlet still line up correctly?

The outlet spigot lining up is the important part.

I am presuming the pan needs to be raised by 25mm to allow the spigot to fit to the outlet and maintain the fall?

OP, as above. You can buy high pans but you'd have to google for them.
If you go the ply/chipboard packing route then you could pre-paint white (?) the edges of the packing pieces.

You can buy a plinth to raise the pan - cant remember where though.

Thanks to everyone for the replies.

The old pan spigot is at a downward angle (approx 20 degrees) and the soil pipe passing through the brick isat the same angle and so they are connected with a fixed straight pan connector.

However, the spigot on the new pan is horizontal, so I've bought a Mcalpine flexible pan connector to cater for the different angles. Hopefully, this will allow me to raise the pan 25mm above the floor and connect to the soil pipe that is at a different angle

I've just had another thought, maybe if I could buy a 25mm thick floor tile that could be drilled and screwed down, that might work.

Thanks again.

i did this a few months ago
with a lot of advice an help here https://www.diynot.com/diy/threads/cutting-oak-plinth.595359/
long thread - but a lot of good advice ,
in the end i used treated softwood - from wickes - made up as a frame and used a template/router to match in
i went up 46mm

Don't forget that a standard pan connector's spigot seal is designed the allow some flex as far as the outflow fall is concerned, as long as it isn't excessive, 20Deg may be ok.

Madrab- I tried connecting the new pan to the soil pipe with the existing pan connector and it leaked. So I bought the flexible connector.

ETAF- Just had a look at your interesting 'Cutting oak plinth' thread and it looks a good idea to put a frame together.

I think I've got a couple of lengths of teak from some old furniture that I could use for a frame.
